    With the rapid development of Asian economy, Asia becomes the largest economic organization in the world,and it contributes the world economy, propels it forward.

    Booming Asian demand and a weaker euro are propelling Germany’s export-driven economy, driving up quarterly profits at some of the country’s biggest companies—from engineering giant Siemens AG to auto maker Volkswagen AG—but those factors may provide less of an earnings boost later this year.

     Siemens, whose broad product range and global reach makes it a bellwether for global manufacturing and the German economy, said Thursday its profit for the quarter ended June 30 rose 9% to €1.44 billion ($1.87 billion) as sales rose 4% to €19.2 billion.

    Chef Executive Peter Löscher cited growth in all businesses, which range from wind turbines to light bulbs to medical equipment. The across-the-board improvement prompted Siemens to raise its full-year operating profit forecast to “clearly” higher than last year’s €7.5 billion; it earlier expected €6 billion to €6.5 billion.

    Volkswagen, whose brands include Audi, Skoda and Bentley, reported its largest quarterly profit since 2008 as profit quadrupled to €1.25 billion from €283 million a year earlier and revenue climbed 22% to €33.2 billion. Much of the profit and sales growth at Europe’s largest auto maker by sales came from China, where car deliveries soared 46% in the first half of the year.

    At BASF SE, the world’s largest chemical maker by revenue, second-quarter profit tripled to €1.18 billion from €343 million on a 30% increase in sales to €16.21 billion.

     The better-than-expected results, which followed a sharply higher profit forecast by Daimler AG this week, underscored the growing strength of Germany’s economic recovery and how much it owes to China and the weaker euro.

     Germany Regains Jobs Lost in Recession BASF’s sales in the Asian-Pacific region rose 55% in local-currency terms and 60% when translated into euros, the company said. Siemens reported a 35% increase in new orders from China and a 51% jump orders from the U.S.

    ”Such order growth last occurred in 2008,” Siemens’s Mr. Löscher said of the company’s total order intake.

    Economists pointed to a further decline in German unemployment as another sign of business confidence in a sustainable economic upswing. The government reported Thursday that Germany’s jobless rate fell to a seasonally adjusted 7.6% in July from 7.7% in June.

    Still, analysts warn that German economic growth is likely to slow in the second half of the year, and that German exporters may find their dependence on China and the U.S. beginning to work against them if growth in those regions slows as well, as some analysts predict. The euro’s nearly 8% rise against the U.S. dollar in July, after hitting four-year lows in recent months, also is likely to make German and other euro-zone products costlier abroad than they were in the second quarter.

    As euro-zone governments grapple with debt problems, further budget cuts across Europe also could crimp still-modest demand closer to home.

    “It’s not good news if a slowdown in exports occurs just as tighter fiscal policies starting to bite,” said Howard Archer, chief European economist at IHS Global Insight.

     Volkswagen, Europe’s largest car maker by sales, has plans to build two additional factories in China to help double its annual production capacity there to three million cars. It said Thursday that it expects full-year sales and operating profit to be “significantly higher” than in 2009. But it added that the robust growth it experienced in the first six months “will not continue undiminished in the second half of the year.

      BASF Chief Executive Jürgen Hambrecht said his company still expects a “considerable” improvement in full-year pretax earnings, and that the global economic recovery will continue at a moderate pace. But he added that demand in the second half will likely be tempered as governments seek to cut budget deficits and wind down stimulus programs. Volatile raw-material markets and excess capacities also could affect demand, he cautioned.
    

Since there are a lot of factors which influence the demand, choose the one suits best.

      Pump is used widely in our daily life, but not everything is perfect, sometimes we will run into some problems. These days some agencies are investigating the performance of pump. such as sustainability, reliability, stability and working efficiency.

  Investigators plan further examination of the fuel pump on a small plane that crashed near Portland International Jetport in Maine, killing two people.

   A preliminary report by the National Transportation Safety Board noted this week that tests of the crash-damaged Yak-52 pointed toward problems with the fuel pump.

   The report says there appeared to be corrosion inside the fuel pump bypass valve and fuel inlet line. A stuck bypass valve could cause the engine to become starved for fuel.

   Pilot Mark Haskell of Brunswick was undergoing biannual certification and had a flight instructor with him when the Soviet training aircraft crashed shortly after takeoff on June 17. The propeller was not turning on impact, indicating that the engine had failed.
  
   So we should fortify our examination of fuel pump when it is produced. You know, these pumps are used in heavy industry, so it should be produced perfectly.

    We will run into a lot of emergencies everyday, some people will die of this, some will survive. What we should do now is preventing these things from happening.
     Emergency crews scrambled Monday in Stephenville after a motorist apparently knocked a gasoline pump out of alignment at a local convenience store, causing about 100 to 150 gallons of gas to spill.

     An area of about the size of a city block was evacuated, including a beauty shop across the street, because of the potential of ignition, fire officials said.

     Fire Chief Jimmy Chew said 12 crew members, three trucks and an ambulance responded to the scene shortly after noon at Lilly’s/NuWay at 1165 Washington St. Chew called for a city dump truck loaded with sand and cut off power to the scene.

    Chew said the sand was used to create a berm on the east side of the building to keep the gasoline from spreading.

    The attendant at the store was unaware of the spill until notified by a customer that the pump was leaking. The attendant then turned the pump off, Chew said.

   “At first it was thought the emergency shut-off did not work,” Chew said. “We think it just took a few seconds for the fuel to stop running, but we shut off power to ensure it was stopped.”

   Chew said someone apparently bumped the gas pump and drove off, either not knowing or not caring about their actions. The pump was not knocked over.

  “I would think someone would know if they hit the gas pump, but maybe not if the vehicle was big enough,” Chew said.

    Andrea Morrow, spokeswoman for the Texas Commission on Environmental Quality, said that the property owner contacted DSC Environmental, a hazardous materials crew in Ranger, and that she was pleased with the rapid response.

    The crew arrived on the scene at about 4 p.m. to begin cleaning up, Chew said.

    Police continue to investigate the incident.

  “We don’t have a lot to go on right now,” Police Chief Roy Halsell said, adding that he was not aware of any witnesses to the accident.

    Halsell said his officers will begin reviewing video footage from the store as soon as power is restored. He said the motorist may be charged with failure to leave identification.

    Soon we are gonna know the result of this emergency.

     Nowadays we will always run into all kinds of emergencies, and these emergencies cause so many damage to our daily life, but sometime it is not that there is something wrong with device, on the contrary, it is the notification which we should inform immediately, because these damage can be recovered when we are informed immediately.

     A lift station failure in St. Louis potentially caused millions of gallons of untreated sewage to flow into the Mississippi River. It’s been fixed, but state regulators want to know why it took four days for them to find out about it.

     The lift station failed last Thursday at a Metropolitan St. Louis Sewer District facility near Jefferson Barracks, with sewage overflowing through a manhole that was covered by the flooding river. It was repaired Tuesday afternoon.

     The failure allowed for up to 4.6 million gallons of untreated sewage to be pumped into the river each day — or potentially more than 18 million gallons over the four-day period, though MSD spokesman Lance LeComb said there was no way to know exactly how much sewage made it into the river.

     LeComb said a combination of factors — both related to persistent flooding — were the culprits. A couple of months ago, a barge making its way downriver during a period of high water drifted into the area around the lift station. The current flood — the Mississippi on Wednesday was about 5 feet above flood stage in St. Louis — made things worse.

     “We think a barge hit one of the structures, created a void or breach, and debris from the river got into the system,” LeComb said. “That combined with the high water — they (the lifts) just blew out.”

     Both MSD and the Missouri Department of Natural Resources downplayed health concerns. DNR spokesman Judd Slivka said the river is at such a high volume and running so fast that it dilutes the raw sewage. No boil orders or other precautions are necessary for those downriver, he said.

     But Slivka said DNR will cite MSD for violating the state Clean Water Act by failing to notify DNR within 24 hours of the lift station failure.

     “Our biggest concern is the notification,” Slivka said. “The pumps failed last Thursday and we didn’t find out about it until Tuesday.”

     LeComb said MSD officials are also puzzled about the communication error. He said MSD has already issued a written report required within five days, “but for some reason that phone call to DNR was not made Thursday.

     “That’s something we take very seriously,” LeComb said. “We’re going to look into it, find out what happened, and take corrective action.”

    Since we can ensure everything happens like what we design, but trouble can be fixed  when we are informed at a short time.

     Gasoline is used everyday to make cars work, nowadays we can’t inmagine our life without gasoline. It plays an important part in our daily life,so there is a great demand of gasoline all over the world. As is known to all, when there is a shortage of gasoline, the price will raise up so fast.
     Drivers across the country woke up to higher prices at the gas pump on Monday, as retail gasoline rose overnight.

    The average price of a gallon of unleaded regular gained half a cent from Sunday at $2.742, according to AAA, Wright Express and Oil Price Information Service.

    In its weekly survey of gas pump prices released Monday afternoon, the Energy Department’s Energy Information Administration said the average price for a gallon of regular rose 2.7 cents from a week ago, to $2.749. California drivers paid the most at $3.13 a gallon, while motorists in Gulf Coast states paid an average of $2.59.

    Wholesale gasoline prices have risen steadily since the beginning of July. Analysts see pump prices rising by a few more cents a gallon before leveling off.

    Oil prices were unchanged on Monday after drifting above $79 a barrel earlier in the session. Benchmark crude settled at $78.98 on the New York Mercantile Exchange. Oil prices held their ground despite the retreat of Tropical Storm Bonnie as a threat to production and supply in the Gulf of Mexico. Oil prices are near the 11-week high of $79.60 reached on Friday, which has left some analysts scratching their heads.

   “Traders and investors continue to like buying oil, for reasons that are not immediately or readily apparent to those steeped in fundamental knowledge,” Cameron Hanover said in a note to investors. The energy consultants said some support for oil prices also comes from positive earnings reports.

   Stocks rose, with the Dow Jones Industrial Average up about 70 points in late-morning trading. The NASDAQ and the S&P 500 also rose. Oil traders often look to equities for signs of overall investor sentiment. On Monday stocks took their cue from better-than-expected new home sales and a stronger profit outlook from FedEx Corp.

   In other Nymex trading, heating oil lost 0.79 cent to settle at $2.0426 a gallon, gasoline gave up 1.64 cents to settle at $2.1058 a gallon and natural gas rose 3.2 cents to settle at $4.612 per 1,000 cubic feet.

   In London, Brent crude added 5 cents to settle at $77.50 a barrel on the ICE Futures exchange.
   As is seen from this article, the price of gasoline is increasing rapidly and steadily. So choose the right time to buy gasoline, do not waste any penny on it.

     Nowadays more and more cars enter our daily life, they cause so much convenient life for people to live, but meanwhile, they cause environment pollution and traffic jam, because of the breakdown of cars. as is concerned, few months ago, blue bird group suffered terrible car breakdown problem.
     Blue Bird has been joined by another taxi company as well as an auto distributor in complaining about broken fuel pumps in their cars causing breakdowns, while state oil company PT Pertamina continued to stand behind its Premium gasoline, saying it was not the problem.

     Express Group president director Daniel Podiman said on Sunday that about 40 of the company’s taxis were suffering broken fuel pumps each day. All of the affected cars were Toyota Limos, the same model used by the Blue Bird Group.

   “This has been happening for the last few weeks. However, we can’t conclude whether the problem is caused by poor-quality Premium fuel supplied by Pertamina or by Toyota’s fuel pumps,” Daniel said.

     Also speaking on Sunday, PT Hyundai Motor Indonesia president director Jongkie Sugiarto said the distributor had seen a sudden rise in requests for fuel pumps over the past few weeks. “Yes, there is a surge in fuel pump demand based on reports from our dealers, but we don’t know what’s causing it,” he said.

    He said Hyundai was investigating what type of cars were experiencing the problem, where they were filling up and the damage to their pumps.

    Last week, Blue Bird, the country’s largest taxi company, announced that 1,200 of its Toyota Limo taxis had experienced pump failures since early June. It blamed substandard Premium fuel for a build-up of sediment in the pumps and said Pertamina may be liable for repair costs, which it estimated at Rp 20 billion ($2.2 million).

    Both Blue Bird and Express purchase subsidized Premium gasoline exclusively from Pertamina at discounted rates. Blue Bird buys around 5.7 million liters of fuel per month for its 11,000 taxis nationwide, according to Pertamina.

    The oil company, meanwhile, has strenuously denied allegations that its Premium fuel is to blame for the fuel pump problems.

    Speaking on Friday, Pertamina president director Karen Agustiawan challenged Blue Bird to prove that Pertamina had downgraded the quality of its Premium fuel.

   “Whoever thinks that our Premium fuel is bad can go ahead and prove it. But if it turns out that Pertamina is right and they are wrong, I will sue them,” she said.

    Karen said recent spot tests of fuel had proven that the quality of Premium fuel was well within the range the government deems acceptable.

    Last week, Pertamina undertook checks on Premium gas sold at 16 stations in Greater Jakarta to monitor for possible quality problems with the fuel. On Friday, it announced that levels in all of the tested samples met state requirements for octane and sulphur content. Low octane in fuel can clog fuel pumps as can high levels of sulphur, eventually leading to breakdowns.

    Johny Darmawan, president director of PT Toyota Astra Mobil, said on Friday that he was aware that Pertamina had carried out quality tests on its fuel. “However, we are still wondering why there are so many cars experiencing breakdowns, and not just Toyotas,” he said.

    Johny said the company planned to sit down with Pertamina next week in an attempt to find a solution to the problem. In the meantime, the car distributor was focusing on fulfilling the increased demand for fuel pumps, he said.

    Commenting on the fuel pump debate, Danang Parikesit, chairman of the Indonesian Transportation Community, blamed the ongoing problems on insufficient government oversight and called for independent testing of the fuel as soon as possible.

    This terrible car breakdown problem is still in investigation,hopefully, we can get a solution as soon as possible.furthermore, cars are used everyday, and if there is something wrong with them, we should solve them A.S.A.P, or many people will die for this unsolved problem.

The water pump is a simple devices, water pump is the heart of the cooling system and continuously keeps the antifreeze/water mixture flowing through the engine, radiator and heater core.

The water pump which is connected to the fan in your car is installed on the front of the engine. In any case, it runs off a drive belt connected to the crank pulley, so there is something wrong with water pump, check the following ones:

l        Identify the belt and check it for proper tension and cracks.

1) Tighten the belts by adjusting either the alternator or the idler pulley if it is too loose.  

2) Inspect the front of the water pump for leaks of coolant, which is green, or engine oil.

3) Grab the fan and wobble it. If there is play from front to back in the fan, the water pump bearing may be going out.

As is known to all, there is a shaft on which the fan mounts. It drives an impeller, which is inside the coolant passages of the engine. There is an oil passage to the bearing which lubricates it. When the bearing goes bad, the coolant will leak out through the worn out bearing and will drip down the front of the engine. In some cases the impeller will slip on the shaft and the water pump will no longer pump. When this happens the engine will overheat, overheating can be caused by many things but don’t rule out the water pump. In this case the fins may be too worn and not allowing enough circulation throughout the system to keep it cool or the water pump is just leaking past the seal and you have lost too much coolant.

Almost every failed water pump will be the result of a bad bearing. You can hear the bearing squeal when the engine is running, usually. If the belt is tight it is probably a bearing. Listen around to determine that it is not an alternator, power steering pump, or AC bearing that has gone bad. If you see anything leaking out of the water pump housing, it will have to be changed.

Water pumps don’t break as often as they used to, but keeping an eye on your coolant level and changing the antifreeze at the proper intervals will help you eliminate problems to the minimum. A broken water pump will quickly leave you stranded and may cause severe damage to the engine if you try to drive too far without the flow of coolant created by the pump. As always if you are worried about the water pump take it to a reputable garage where they can at least pressure test the coolant system and see if there is weakness in system anywhere.

Although problem-free pump operation is the primary goal of all pump operators, achieving that goal is not a simple matter. The key components of a pump — mechanical seals, impellers, couplings, roller bearings and housings — are all subject to wear. Keeping a pump in good working condition is essential for cost-effective and reliable operation of plants and systems. Unplanned downtime can ruin production schedules and adversely affect a facility’s bottom line.

“Any system can only be as functional as the lifespan of its weakest component” — this statement applies to many types of products — but is especially true of mechanical seals. While mechanical seals are one of the key components of a pump, they also have one of the shortest average service lives. Mechanical seals are recognized to be responsible for most pump failures and consequently represent the highest cost for pump repairs. Therefore, reducing the MTBF (mean time between failure) or the MTBR (mean time between repair) can significantly improve pump operations and save money.

When working properly, mechanical seals are generally safe and reliable components that operate virtually wear-free. Problems occur when the sliding faces of a mechanical seal are not adequately lubricated, resulting in a dry-running condition that ultimately causes the destruction and breakdown of the seal. Industry surveys have shown that dry running or inadequate lubrication are responsible for more than 50% of all mechanical seal damages; consequently, it is safe to state that approximately 20% of all pump failures are due to poor lubrication or dry running of the mechanical seal faces.

In an analysis of the service life of pump components, it was found that mechanical seals, with an average service life of only 1.2 years, are the weakest link in terms of pump components, compared to the next weakest component, bearings, with an average service life of three years. To minimize pump repairs and downtime, it would be advantageous to pump operators if the average service life of the mechanical seals increased to match the service life of the bearings.

By using mechanical seals coated with DiamondFaces, the average service life of mechanical seals substantially increases. This allows pump operators to schedule preventive inspections of mechanical seals and eliminate or reduce the costs of unplanned process interruptions. By increasing the service life of mechanical seals, approximately every second pump repair, along with associated downtime and production disruption, can be avoided.

These diamond crystals grow together to form a closed layer. The separation process is stimulated with tungsten filaments stretched horizontally or vertically across the reactor and heated to approximately 2,000 C. This arrangement of the tungsten filaments is one of the key factors for ensuring that the coated seal faces are perfectly flat and uniformly coated. DiamondFaces guarantees the evenness of the sealing faces, which is essential for the functional reliability of mechanical seals.

Mechanical seals coated with DiamondFaces offer many advantages for users such as:

·        Virtually no wearing of the diamond coating

·        Reduced sliding-face friction

·        Extension of MTBF and MTBR values

·        Significant energy savings

·        Increased application range

·        Shortened ROI (return-on-investment

These advantages can make the pump have long life and can serve people for a long time.

A heat pump is a device that uses a small amount of energy to move heat from one location to another. Heat pumps are usually used to pull heat out of the air or ground to heat a home or office building, or they can be switched into reverse to cool a building. If you know how an air conditioner works, you already know a lot about how a heat pump works, because heat pumps and air conditioners operate in very similar ways. And that’s the reason why it is becoming popular. Heat pump are all around you, reverse cycle air conditioners are heat pump, as are dehumidifiers, many heat recovery/water heating units and process dryers.

Heat pumps are a unique kind of heating system, because they can do the work of both a furnace and an air conditioner. Thus, there’s no need to install separate systems to heat and cool your home. Heat pumps can also work extremely efficiently, because they simply transfer heat, rather than burn fuel to create it. Now with the rapid development of technology, heat pump technology is available today, heat pumps offer levels of efficiency unattainable by boilers or electric heating, heat pumps reduce CO2 emission and are recommended by the government sponsored carbon trust as a renewable technology.

Heat pumps work best in moderate climates. If you live in a moderate climate, using a heat pump instead of a furnace and air conditioner may help you save money on your utility bill. Most heat pumps are somewhat limited by the cold, however, so it is important that you learn which kind of heat pump is best for your area before installing one in your home or office building. If you install the wrong kind of heat pump, you may end up paying even more in energy costs than you do already

Heating and cooling uses the relatively constant temperature of the earth to heat and cool homes and businesses with 40% to 70% less energy than conventional systems. While conventional furnaces and boilers burn a fuel to generate heat, heat pumps use electricity to simply move heat from the earth into buildings, allowing much higher efficiencies. The most efficient fuel-burning heater can reach efficiencies around 95%, but a heat pump can move up to 4 units of heat for every unit of electricity needed to power the system, resulting in a practical equivalence of over 400% efficiency.

A pump is a device used to move fluids, such as liquids or slurries. A pump displaces a volume by physical or mechanical action. Pumps fall into five major groups: direct lift, displacement, velocity, buoyancy and gravity pumps. Their names describe the method for moving a fluid. Pump can be simply divided into several catalogs, such as, positive displacement pumps, buoyancy pump, impulse pumps, velocity pumps, gravity pumps, steam pumps and so on.

Pumps are used throughout society for a variety of purposes. Early applications include the use of the windmill or watermill to pump water. Today, the pump is used for irrigation, water supply, gasoline supply, air conditioning systems, refrigeration (usually called a compressor), chemical movement, sewage movement, flood control, marine services, etc. Because of the wide variety of applications, pumps have a plethora of shapes and sizes: from very large to very small, from handling gas to handling liquid, from high pressure to low pressure, and from high volume to low volume.

One sort of pump once common worldwide was a hand-powered water pump over a water well where people could work it to extract water, before most houses had individual water supplies.

From this came the expression “parish pump” for “the sort of matter chattered about by people when they meet when they go to get water”, “matter of only local interest”. However water from pitcher pumps are more prone to contamination since it is drawn directly from the soil and does not undergo filtration, this might cause gastrointestinal related diseases.

Today, hand operated village pumps are considered the most sustainable low cost option for safe water supply in resource poor settings, often in rural areas in developing countries. A hand pump opens access to deeper groundwater that is often not polluted and also improves the safety of a well by protecting the water source from contaminated buckets. Pumps like the Afridev pump are designed to be cheap to build and install, and easy to maintain with simple parts. However, scarcity of spare parts for these type of pumps in some regions of Africa has diminished their utility for these areas.

Finally, let’s talk about pump efficiency. Pump efficiency is defined as the ratio of the power imparted on the fluid by the pump in relation to the power supplied to drive the pump. Its value is not fixed for a given pump, efficiency is a function of the discharge and therefore also operating head. For centrifugal pumps, the efficiency tends to increase with flow rate up to a point midway through the operating range (peak efficiency) and then declines as flow rates rise further. Pump performance data such as this is usually supplied by the manufacturer before pump selection. Pump efficiencies tend to decline over time due to wear (e.g. increasing clearances as impellers reduce in size).

One important part of system design involves matching the pipeline headloss-flow characteristic with the appropriate pump or pumps which will operate at or close to the point of maximum efficiency. There are free tools that help calculate head needed and show pump curves including their Best Efficiency Points (BEP).

Pump efficiency is an important aspect and pumps should be regularly tested. Thermodynamic pump testing is one method.
