Waterladder Pump
A waterladder pump, water ladder, dragon spine, dragon wheel or rahad is a low lift pump which is composed of sprockets that move a chain with paddles over a trough. Water is pumped as the paddles push the water up the trough. Application The water ladder, as many low lift pumps, is commonly used for irrigation purposes and for drainage of lands. It is currently still used by farmers in south-east Asia. Advantages The water ladder was built as an alternative to the paddle wheel to get around the problem that to lift water to a greater height, a bigger wheel is needed. Despite the emergence of new pumps that operate on other principles, the water ladder remains an important tool as some of its other benefits are that they can be built and repaired easily at a very low cost. This is possible as all the components can be built from local resources, such as wood; which can be obtained and shaped into the desired form easily. Disadvantages As mentioned before, the pump only allows th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watering Trough
A watering trough (or artificial watering point) is a man-made or natural receptacle intended to provide drinking water to animals, livestock on farms or ranches or wild animals. History In Australia, the watering trough is established so that sheep, cattle and other domesticated animals can drink, but native species such as kangaroos may be attracted. To reduce this, some water troughs are designed to reduce their use of the trough or exclude them from that use. One design is the "Finlayson Trough", which uses a low-lying electrified wire that sheep usually step over but kangaroos cannot. Watering troughs were very common in many towns and cities as a means for horses to drink while they were tethered to a post. In 1927 animal lovers, Annis and George Bills, funded the building of up to 500 watering troughs in Australia, Ireland, England and the United States. Many can still be seen today inscribed with ''Donated by Annis and George Bills Australia''. Nowadays, manufactu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddle Wheel
A paddle is a handheld tool with an elongated handle and a flat, widened end (the ''blade'') used as a lever to apply force onto the bladed end. It most commonly describes a completely handheld tool used to propel a human-powered watercraft by pushing water in a direction opposite to the direction of travel (i.e. paddling). A paddle is different from an oar (which can be similar in shape and perform the same function via rowing) – an oar is attached to the watercraft via a fulcrum. The term "paddle" can also be used to describe objects of similar shapes or functions: *A rotating set of paddle boards known as a paddle wheel is used to propel a steamboat or paddle steamer. *In a number of racquet sports (e.g. ping-pong and paddle ball (sport), paddle ball), a "paddle" or "bat" is a short, solid racket (sports equipment), racket used to strike a ball. *A mixing paddle is a device used to stir or mix separate ingredients within a mixture. *A spanking paddle is used in corporal puni ...

Rope Pump
A rope pump is a type of pump that uses a loose-hanging rope, which is lowered into a well and drawn up through a long pipe, with its bottom end submerged in water. Round disks or knots, matching the diameter of the pipe, are attached to the rope, allowing water to be pulled to the surface. The rope pump is commonly used in developing countries for both community water supply and self-supply. It can be installed on boreholes or hand-dug wells, providing an affordable and efficient water-lifting solution. Description A rope pump is a type of pump of which the main or most visible component is a continuous piece of rope, in which the rope is integral in raising water from a well. Rope pumps are often used in developing areas, the most common design of which uses PVC pipe and a rope with flexible or rigid valves. Rope pumps are cheap to build and easy to maintain. One design of rope pump using a solar-powered rope pump can pump 3,000 litres to 15 meters per day using an 80 watt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparison Of Pumps
This article lists different types of pump A pump is a device that moves fluids (liquids or gases), or sometimes Slurry, slurries, by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy. Mechanical pumps serve in a wide range of application ... and provides a comparison of certain key design features. Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping from wells). Direct lift devices Displacement pumps Velocity pumps Buoyancy pumps Impulse Pumps Note: reciprocating pumps are cyclic, rotary pumps are typically continuous.

Chain Pump
The chain pump is type of a water pump in which several circular discs are positioned on an endless chain. One part of the chain dips into the water, and the chain runs through a tube, slightly bigger than the diameter of the discs. As the chain is drawn up the tube, water becomes trapped between the discs and is lifted to and discharged at the top. Chain pumps were used for centuries in the ancient Middle East, Europe, and China. In the Near East and Europe The earliest evidence for this device is in a Babylonian text from about 700 B.C. They were commonly powered by humans or animals. The device then appeared in ancient Egypt from about 200 B.C., featuring a pair of gear-wheels. A version of the chain pump was used in ancient Greece and Rome, sometimes with pots, or scoops fixed to the chain, which, as they passed over the top pulley, tipped the water out; a 2nd-century example is preserved in London. Philo of Byzantium wrote of such a device in the 2nd century B.C.; the historia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumps
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy. Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis. When a pump contains two or more pump mechanisms with fluid being directed to flow through them in series, it is called a ''multi-stage pump''. Terms such as ''two-stage'' or ''double-stage'' may be used to specifically describ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
