Handpump
Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities. There are many different types of hand pump available, mainly operating on a piston, diaphragm or rotary vane principle with a check valve on the entry and exit ports to the chamber operating in opposing directions. Most hand pumps are either piston pumps or plunger pumps, and are Pump#Positive-displacement pump, positive displacement. Hand pumps are commonly used in developing countries for both community supply and Self-supply of water and sanitation, self-supply of water and can be installed on boreholes or hand-dug Water well, wells.

Village Level Operation And Maintenance
Village Level Operation and Maintenance (VLOM) is an unofficial classification given to handpumps used in developing countries that require minimal maintenance or that can be done "at the village level." Not all maintenance and repair needs to be done by the villagers for a pump to be classed as a VLOM pump. VLOMM, or Village Level Operation and Management of Maintenance is often used synonymously. This addition emphasizes the role of users as the managers of maintenance able choose to use someone from outside the village to assist with more complicated repairs. History During the International Drinking Water Decade, 1981-1990, first UN decade on water boreholes, hand-dug wells and tubewells were constructed and water pumps were provided to developing countries by various NGOs. Unfortunately this top down approach led to the installation of pumps, notable the India Mark II, that were difficult to maintain. VLOM pumps were designed to allow remote villages to maintain pumps thems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Well
A well is an excavation or structure created in the ground by digging, driving, or drilling to access liquid resources, usually water. The oldest and most common kind of well is a water well, to access groundwater in underground aquifers. The well water is drawn up by a pump, or using containers, such as buckets or large water bags that are raised mechanically or by hand. Water can also be injected back into the aquifer through the well. Wells were first constructed at least eight thousand years ago and historically vary in construction from a simple scoop in the sediment of a dry watercourse to the qanats of Iran, and the stepwells and sakiehs of India. Placing a lining in the well shaft helps create stability, and linings of wood or wickerwork date back at least as far as the Iron Age. Wells have traditionally been sunk by hand digging, as is still the case in rural areas of the developing world. These wells are inexpensive and low-tech as they use mostly manual labour, ...

Hand Pump-en
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the koala (which has two opposable thumbs on each "hand" and fingerprints extremely similar to human fingerprints) are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking. Some evolutionary anatomists use the term ''hand'' to refer to the appendage of digits on the forelimb more generally—for example, in the context of whether the three digits of the bird hand involved the same homologous loss of two digits as in the dinosaur hand. The human hand usually has five digits: four fingers plus one thumb; these are often referred to collectively as five fingers, however, whereby the thumb is included as one of the fingers. It has 27 bones, not including the sesamoid bone, the number of whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
