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.

If your oil pump has the following situation, may be you should chang it.

Low Oil Pressure

* The most obvious sign of a bad oil pump is a low engine oil pressure reading. A bad oil pump loses its ability to pump and pressurize motor oil throughout a car’s engine, a condition that can read as a low oil pressure reading on an oil pressure gauge.

Engine Overheating

* Adequate engine oil flow is critical for maintaining proper engine operating temperature. A bad oil pump diminishes both oil flow and pressure, both of which impedes engine oil flow and can increase an engine’s operating temperature.

Engine Lifter Noise

* Engine hydraulic lifters require adequate oil lubrication in order to function properly. A bad oil pump can cause hydraulic lifter noise by reducing the amount of oil lubrication that flows to these critical engine valve-train components.

Engine Valve Noise

* Just as hydraulic lifters require adequate oil lubrication to function properly, engine valves require adequate engine oil flow in order to work properly and quietly. A bad oil pump can lead to noisy valves by limiting the amount of oil flow to an engine’s valve-train.

Excessive Engine Wear

* One of the main jobs of circulating engine oil is to reduce friction within a car’s engine. A bad oil pump reduces engine oil flow and pressure throughout an engine, a condition that leads to increased engine friction and increased engine wear.

Pump Room is one of the most popular restautants in Bath, British. It is right next door to the Roman Baths and Bath Abbey, above Kings Bath.

1738–Start of the construction of The Royal Mineral Water Hospital reflected a new period of faith in the healing properties of the waters. It is also notable as the only building on which the three men most responsible for the construction of Georgian Bath–John Wood the Elder, Beau Nash and Ralph Allen–collaborated. While the beneficial and healing properties of the water have always been acknowledged, modesty and decency have not always been inherent in Bath’s “spa culture.” John Wood the Elder writes at this time: “The Baths were like so many Bear Gardens, and modesty was entirely shut out of them; people of both sexes bathing by day and night naked.”

1777–Hot Bath rebuilt to the design of John Wood the Younger.

1783-98–Cross Bath rebuilt and then enlarged.

1788–New Private baths (now demolished) built between King’s Bath and Stall Street.

1790s–Great Pump Room built. While excavating the foundations for the new Great Pump Room, many of the first finds relating to the Roman Temple were made.

1798–The publication of “The Comforts of Bath,”a satirical view of life in Bath, reflects the infamous lifestyle of elements of Georgian society. The Pump Rooms and the baths were the center of much revelry throughout this period when Bath became known as the “premier resort of frivolity and Fashion”.

The Grand Pump Room was officially opened by the Duchess of York on December 28, 1795. The elegant hall still looks much the same as when it was first built, aside from the addition of tables and chairs.

The Grand Pump Room was originally left empty of furnishings, leaving visitors to mingle about in spacious elegance. The room was heated by two large fireplaces and musicians entertained guests from the west apse (as they still do). Hot mineral water from the springs was pumped to a fountain where an attendant filled glasses for those who wished to drink it.

“I’m afraid it will be very objectionable,” I overheard a lady saying as she entered the Grand Pump Room, obviously for the first time in her life, intent on drinking some of the water.

“Not at all, madam,” the uniformed attendant reassured her. “It is a little warm and has a slight taste; that is all.”

– H.M. Bateman, Bath, Past and Present, 1939

In Victorian times, it was customary to drink a prescribed number of glasses of the curative mineral waters before breakfast, so the doors opened at 6am in summer and the room was fully packed by 8am. The Grand Pump Room was the place to see and be seen; where Jane Austen’s Northanger Abbey ladies “walked together, noticing every new face and almost every new bonnet in the room.”

Tea in the Pump Room doesn’t come cheap (£23 for two), but as a one-time splurge it is really worth it. I highly recommend the Traditional Pump Room Tea pictured at right. The clotted cream is divinely rich (just a step away from butter), the scones are moist and fresh, and the tiny sandwiches are perfection. Then there are the sweets, which are very rich and very good.

And of course, no visit to Bath is complete without a taste of the warm mineral water from the sacred springs (50 pence for a small glass) - the taste is indeed “objectionable” but has long been believed to cure all your ills.

The atmosphere of the Pump Room is elegant and historic without being intimidating (casually-dressed tourists are welcome) and the service is prompt and unobtrusive.

Interesting items of antique furniture line the walls of the room. The clock was given to Bath in 1709 by Thomas Tompion, England’s best known clockmaker.

The Pump Room Trio entertains diners and water-drinkers with classical music Monday to Saturday mornings and Sunday afternoons. A solo pianist plays every lunchtime and afternoons in the winter.

Tip: Your indulgence in the Pump Room is probably best left until after your sightseeing, as it is so rich that you may not feel too energetic afterwards (at least we didn’t)!

Tip #2: You don’t have to dine at the Pump Room to try the mineral water.

In today’s upstream and midstream oil and gas environment, screw pumps are playing a larger role in what has traditionally been a centrifugal and reciprocating pump market. This is due in large part to technological innovation by screw pump manufacturers and the industry’s need to pump heavier crude oils. Both twin screw and three screw pumps are successfully operating in multiphase, heavy crude oil and crude oil/water emulsion applications.

The oil and gas industry is producing, transporting and refining more unconventional, heavier grades of crude oil from places such as Canada, California, Mexico and South America. Crude oil from these areas is highly viscous, often requiring diluent, steam or other stimulation just to flow the oil from the reservoirs to the pipelines. These nontraditional grades of crude oil are ideally suited for pumping with a screw pump.

Depending on the actual application, either twin screw or three screw pumps are used in crude oil pipeline services. Three screw pumps are typically found boosting pressure from laterals to the main pipeline, while twin screw pumps are predominantly utilized in the main pipeline boosting stations. The primary advantages of screw pumps include the ability to handle a wide range of viscosities; centrifugals can vapor lock while pumping diluent blended crude oils and become extremely inefficient when pumping crude oils heavier than 250 cSt. Screw pumps have extremely low pulsation, eliminating the need for pulsation dampeners or complicated pipeline support systems required by reciprocating pumps.

Three Screw Pumps

Three screw pump designs are generally capable of flow rates exceeding 1100 gpm and differential pressures up to 1700 psi. The pump consists of three rotors, one power and two driven; one externally lubricated bearing capable of handling thrust loads induced by high inlet pressure; one balanced mechanical seal; a liner; a casing and a bearing/seal housing. The power rotor (coupled to driver) performs the pumping work, while the idlers act to seal off the pumping chambers. The torque is transmitted to the driven rotors by a rolling contact. The pumped fluid creates a barrier between the rotating elements, preventing metal-to-metal contact of the rotating elements. The liquid film also supports the rotors in the liner, eliminating contact between the rotors and the liners.

As crude oil enters a three screw pump, it fills the suction pumping chamber of the screw set; as the screws turn, crude oil is conveyed from suction to discharge. This positive displacement action simply moves a volume from suction to discharge, as if it were an infinite stroke piston without the need for complicated internal porting and valving.

In most cases, three screw pumps are used in applications where sand and particulate have been removed from the crude oil (i.e. pipeline grade crude oil).  However, since some particulate may have survived the crude oil settling process, most pumps are available with alternative liner coatings to prevent premature wear, and the rotors are normally hardened.

Three screw pumps usually boost pipeline lateral pressures to the main pipeline that flows to a refinery or terminal. The main pipelines usually require higher flow rates and pressures, which is best accommodated by large twin screw pumps. Today, twin screw pumps have flow capabilities exceeding 11,500-gpm and differential pressures to 1,400-psi.

Twin Screw Pumps

Twin screw pumps are hydraulically balanced, pulsation free and deliver a given volume from suction to discharge, meeting whatever back pressure the system puts on the pump. The pump has two rotors, one drive and one driven, and relies on the pumped fluid to fill the clearances between the rotors and rotors and liner. The pumped fluid seals the individual pumping chambers of the screw profiles, allowing the pump to maintain prime. In a rigid rotor design, the liquid acts as a sealing mechanism only and does not act as a bearing support for the rotors.

The rotors are supported on both ends by bearings, and torque is transmitted from drive to driven rotor via timing gears. By eliminating rolling contact between rotors, as is the case with three screw pumps, twin screw pumps can handle everything from water to heavy crude oils.

In most designs, the timing gears and bearings are external to the pumped fluid. The timing gears are oil lubricated, while the bearings are lubricated by grease or oil. Depending on differential pressure requirements, the bearing and timing gears may require a forced lube oil system to properly dissipate heat and improve overall component reliability.

Since there are at least four bearings in a twin screw pump, there are four shaft penetrations and four mechanical seals. Seals are available in both single and double seal configurations, depending on the actual service. Single seals are typically used for crude services, while double mechanical seals with a barrier fluid system are also available.

Twin screw pumps are increasingly popular in the midstream market, where their ability to handle high viscosities allows operators to pump colder or use less diluent. This is especially evident in ongoing pipeline projects bringing heavy Canadian crude oil to the American Market.

Multiphase Applications

The evolution of twin screw pumps has led to their implementation in multiphase applications. Twin screw style pumps dominate the upstream market in multiphase applications due to their operational flexibility and economical installation. Multiphase pumps boost the untreated flow stream produced from oil wells to downstream process or gathering facilities. This means the pumps handle 100 percent liquid to 100 percent gas (with recirculation) and every combination in between. These pumps are packaged for land-based, offshore and subsea applications.

Multiphase pumps are typically found in the following services:

• Lower well head pressure-As reservoirs mature, their natural pressure declines and production decreases. Multiphase pumps are able to boost the flow line pressure, allowing increased production flow rates, while bucking downstream line pressure.  By drawing down well head pressure, additional production will occur as the inflow to the production tubing increases.
• Reduced facilities-Rather than separating the gas from the liquids, treating the phases and then compressing and pumping the individual phases, multiphase pumps handle untreated well flow with one piece of equipment. By utilizing one piece of equipment, economic justification is significantly higher for remote single well production and well cluster development with centralized process facilities.
• Flow assurance-Multiphase pumps deliver a constant flow at a given speed regardless of system pressure. By changing the pump speed, operators can optimize the flow rate and inlet pressure, thus boosting total reservoir recovery, improving end of life production and reducing paraffin or hydrate buildup.

Current multiphase pump designs deliver up to 330,000-bpd (total flow) at differential pressures up to 1,200-psi. Given the current trend toward deepwater development, the oil and gas industry has recently identified the need for multiphase pumps capable of flows up to 600,000-bpd (total flow) and differential pressures exceeding 2,400-psi.

The operational flexibility, higher efficiency and robustness of screw pumps make them ideal candidates for an increasing array of applications within the oil and gas industry. Ongoing development of screw pump technology will only broaden their use in multiphase, crude oil, emulsion and produced water services.

Barbecue is a very delicious food, people in different countries around the world have their own different ways of barbecue. However, it is difficult to avoid scorch in the babecue. Some people think it is more delicious when the meat scorched a little, but the study shows that it is harmful to health because the scorched meat contains cancer-causing substances.

So a company has developed this water-cooled barbecue. It’s principle is very simple that the traditional barbecue stick is made into hollow metal pipes, and then use circulation pump and condenser to make the cold water circulating in the barbecue, to reduce its temperature, thus avoiding the scorched.
