Welcome to my pump blog! Here is the professional blog about all kind of pump technical articles, such as water pump, centrifugal pump, pressure pump, gas pump and so on.What's more, we supply you funny pump products and uses.

1. Temperature. First of all, you must come to terms with what you can expect from your heat pump. What is the climate in your region? Does weather remain pretty temperate, or do temperatures swing violently in either direction during a year? A heat pump will not suffice in freezing and the most extremely cold weather. For much of the year, the heat pump will work like a charm for you, but when the temperatures drop into the deep freezing dead of winter, you really need a backup heating source. If you can afford both heat pump and gas furnace, this setup makes the most sense; the gas furnace will be most efficient below 30 degrees Fahrenheit, while above that temperature (until around 70 degrees) the heat pump will work best.

2. Air-source. We’re all fairly familiar with the function of air conditioners. An air-to-air heat pump works basically the same way, except that it can switch from providing cold to providing heat (these heat pumps each have a valve that determines the direction that the refrigerant flows within the device).

Air-source heat pumps won’t require the contractors to dig into your yard and bury anything, as will the ground-source heat pumps. (Who knows what they might dig up?) However, you’ll have to deal with the fact that the heat pump extends out into the cold, where frost can build up. Because the frost hampers the ability of the heat pump to provide heat, the heat pump has to occasionally divert its attention to thawing itself out! This disrupts the flow of heat into your house until the heat pump has satisfactorily thawed itself.

3. Ground-source. Ground-source heat pumps serve the same purpose, but instead of moving heat from the outside air into your home, they move heat from the ground (earth) into your home in cold months, and transfer heat from your house back into the ground in the summer. Since earth temperature is pretty steady, and warmer in winter months than the outside air, performance can remain closer to the same level year-round.

Though digging (vertically or horizontally, depending upon available space) will be required to install the piping of the heat pump underground, these heat pumps will not suffer the frost frustration that air-source heat pumps have to endure; the whole heat pump unit, minus the underground piping, is actually indoors.

4. SEER and HSPF Ratings. Consider these ratings when choosing a heat pump. SEER (Seasonal Energy Efficiency Rating) refers to the efficiency of the heat pump acting as an air conditioner, while HSPF (Heating Seasonal Performance Factor) tells you how efficient the heat pump works as a heating unit. If you can, choose the heat pump that is most efficient.

5. Size. You could probably get away with heating and cooling exclusively on a heat pump, but you’d be better off relieving your heat pump with a different heat source in the coldest parts of the year; heat pumps aren’t as efficient in extreme cold.

Now a days, mobile is not only used for talking to somebody. People are coming up with new innovative ideas to use mobile phones. You can Turn your Windows Mobile Phone Into Wi-Fi Router, you can make 10 Ways to Make Payments via Mobile In India, you can Convert your cell phone into BlackBerry etc.

One company in Pune has come up with a nice idea to operate motor pumps using mobile phones. Remote Data Exchange, Pune have come up with a solution called Jai Kisan. Jai Kisan is a Hi-tech, Ultra low cost device which is India´s only device for use of controlling Motor Pumps from any location.

The way it works is, Motor Pump is connected to an auto start, autostart is connected to Jai Kisan Device. One mobile is kept near Jai Kisan device which can trigger the motoro pump to start and stop. A person has to just call to Mobile kept near Motor pump and press his code to Start or Stop the Motor. He can also know weather power is present or not.

The question here is, who would charge the mobile that is kept near the Jai Kisan Device? In the country where there are millions of stolen mobile phone cases, how can it be protected?

The treadle pump is based on a design developed in the 1970s by Norwegian engineer Gunnar Barnes. It can be made locally. A group based in the United States, IDE, International Development Enterprises, has created programs in different countries.

The program in India won an Ashden Award in 2006 for using local sources of energy to improve quality of life. Last year the Bill and Melinda Gates Foundation awarded IDE 27 million dollars. The money is to be used to expand small irrigation projects to the other half of India’s 28 states.

The treadle pump is easy to build from bamboo or other wood and two metal cylinders with pistons. The pistons go up and down as a person stands on lever devices — treadles — and uses a natural walking motion.

How many hours a day the pump needs to be operated depends on the season and how much water is needed for crops. It could be two hours a day. It could be seven hours a day.

Small children sometimes stand with their parents on the treadles. Everyone in the family can take turns operating the pump.

The Acumen Fund is a nonprofit group that invests in business projects to fight poverty. It studied the effects of treadle pumps in the Indian state of Uttar Pradesh. Uttar Pradesh has three treadle pump manufacturers and more than 73 thousand pumps.

Acumen reported that families using them ate more vegetables, because they were able to grow more to eat and to sell. Many of these families also drank more milk, because they bought a cow with their added earnings. Men with treadle pumps often no longer have to leave the farm to seek extra work in cities.

The pumps can also improve education. Farmers often use their extra earnings to buy books for their children or to pay for schooling.

A farmer in Zambia said he hoped to have enough money in three years to buy a diesel powered pump. Then he could grow more crops over a larger area.

But the world economic crisis has had an effect on some farmers. IDE executive director Zenia Tata says some who were able to buy diesel pumps now do not enough money to buy fuel. So they are using their treadle pumps again.

Like most things in life, the rope pump is not a package of unmitigated joy and happiness. There are a few drawbacks. These include depth limitations and possible water contamination.

While the rope pump is effective for shallow wells, it is less effective for deeper wells. Unfortunately, it is not easy to predict how deep a well can be in which a rope pump will work.

The unpredictability arises from the use of local materials with no universal standards. Both the diameter and thickness of the valves, for example, affect how deep a well may be (on which to put a rope pump). Because inner tubes and leather come in several thicknesses, and because the valves are cut by hand by local artisans, they are not uniform. If the valve is too thin and flexible, it bends and releases water down to the valve below it on the rope.

As wells are more deep, the water weighing on the bottom valve may be so heavy that it all leaks down before it can be brought to the top of the well. Similarly, even if it is not too flexible, it may not be cut to precisely the diameter of the inside of the pipe, and water will again leak to the valve below. This problem, too, increases with the depth of the well. If the valve is cut to fit too tightly against the inside of the pipe, in contrast, it might more effectively bring the water up the pipe, but that might also add to the difficulty of cranking the wheel at the top. At some point the wheel will be too difficult to turn by hand. This problem, too, increases with the depth of the well.

Since these are unpredictable variables, it is not yet possible to state what is the maximum depth of well on which a rope pump will be effective. Perhaps it is 35-45 metres.

Another drawback is a potential for well contamination. The rope pump described above does not indicate that the well should be covered. There is a tendency for local people to omit covering the well, because that takes time, money, effort and desire (based on hygiene knowledge). If the well is uncovered, little animals can get into it and defecate or die or both. Human wastes and parasites can even find their way into the well if hands are not clean when the wheel is cranked.

A good well cover will allow the pipe to come up above it, before diverting the water pulled up by the upcoming rope to a container. A simple hole in the cover for the down going rope may be satisfactory. It will certainly be improved by installing a short piece of pipe, a little wider than the main pipe, above the cover, so that the valves can easily go into it, along with the rope, back down into the well.

When the residents of the community are not so concerned about hygiene (the norm, unfortunately, rather than the exception), and short on resources, they may be more tempted to omit the cover, thus allowing an increased potential for well contamination.

Appropriate training and effective hygiene public awareness may decrease the effects of these drawbacks.

While these are recognized drawbacks to using a rope pump, they are not major problems. Experts with vested interests in using hand pumps, however, will exaggerate them, and omit telling you that the costs of dealing with such minor drawbacks are far lower than the costs of using hand pumps.

The rope pump, now popular in Central America, is quite simple. It consists of a continuous loop of rope. It is wrapped around a bicycle wheel at the top of the well.

It hangs loose down into the well, and then is brought up through the inside of a plastic pipe to the top again. On the rope are attached valves, made from used inner tubes (or any suitable flexible material such as used shoe leather), every 20 to 30 cm. The bicycle wheel can be cranked by hand so that the rope moves down the outside of the pipe and then up again inside the pipe. A bicycle frame can be modified by a welder and with a hacksaw to hold the bicycle wheel, and the foot pedals modified to become a hand crank. As the rope comes up the inside of the pipe, the valves push water from the bottom of the well to the top. A junction is made into the pipe near the top so the rope continues up to the wheel while the water spills out of the pipe to a waiting container.

Students Make Rope Pump at Science Fair

All the components of the rope pump are usually available in any medium sized town: rope, used inner tubes, used bicycle frame and wheel, and plastic pipe. None is very expensive.

The rope pump has been around for years, perhaps decades, but in the past few years it has become popular and widely used in Nicaragua.

A Commerce utility department employee was taken to an Athens hospital Monday morning after suffering burns to his face and arms while working on water system pump station near Banks Crossing.

It appears an electrical fire started when equipment at the city’s Beck Road pump station malfunctioned at about 8 a.m., according to Steve Nichols, director of Jackson County Emergency Services.

The worker received first-degree burns to his face and arms.

Paramedics treated the man at the scene and took him to Athens Regional Medical Center, where he is in stable condition, according to a news release issued by Nichols.

Beck Road runs off U.S. Highway 441 on the north side of Commerce, near Banks Crossing and Interstate 85.

Maybe you will think it is impossible, How can a skirt can be used as a seat? But I will tell you it is true. According to the inventor’ s introduction, this oddity skirt is for making the tedious walking more interesting.

This skirt is very strange. It consists of  a pair of shoes with a pump and a skirt made of seven plastic bags. when walking, it use the pressure of your feet to pump the air into the back plastic bags. When a certain air filled into the back of the bag, the user can seat on it for rest. Because of the gravity, the air inside the bags will gradually be released. At this time, the user will need to walk again to repeat the front process.

This is Britain’s finest Victorian Water Works and the only one in the Midlands to be preserved as a complete working water pumping station. Papplewick Pumping Station was built between 1882 - 1884 to supplement the water supply for the growing city of Nottingham.
In the main building there are two massive beam pumping engines, thought to be the last built by the famous firm of James Watt & Co. of Soho Works, Birmingham and London.
These two 140hp. Engines lifted water from the 200 foot deep well, dug into the sandstone subground and pumped the water into the reservoir that supplied Nottingham.
These beams engines worked for 85 years and ceased regular operation in 1969, when electric pumps were fitted in the pilot well near the main gate. These automatic electric pumps saved the manpower required to stoke three of the 6 Lancashire boilers that feed steam to the two beam engines.
After the preservation group took over the upkeep of the station in 1974 and by 1975 Papplewick was opened to allow the public to view this fine water works, along with a growing number of other steam powered engines that have come from other local sites. These include the Linby Colliery Winding Engine and the Stanton Triple Expansion Engine.
Other Waterworks in the Nottinghamshire area only survive as preserved buildings without any of the original steam powered pumping equipment.

The Army Corps of Engineers has broken ground on a serious construction project: a 150,000-gallon-per-second, $500m pumping station charged with keeping the city of New Orleans a little, uh, dryer than it has been in the last few years.

The pump is just a small part of a larger $14bn plan to seal up New Orleans’ levees and bolster the city’s disaster preparedness, but it’s without a doubt the most visually impressive. PopSci’s thrown together a couple of diagrams to give us a sense of scale, and trust me, they’re necessary—see that little white thing next to the diesel engine? That’s a full-sized human being. There aren’t a whole lot of companies that make combustion engines that cartoonishly huge, so my money’s on something from a company like Wartsila-Sulzer, which makes engines like this to spin the props on ultramassive cargo ships, and conceivably, pumps:

At any rate, the pump is expected to be operational—and NOLA slightly safer—by 2011.
