2.1 技术简介

技术定义:

A treadle pump is a foot operated water lifting device that can be used by smallholder farmers to irrigate their land in places where the water table is high.

2.2 技术的详细说明

说明:

A treadle pump is a simple, cheap, and effective device for lifting water. In this technology, bamboo levers are pushed repeatedly by foot to provide the driving power to lift water. This simple device is relatively easy to install and maintain and is environmentally friendly. Three types of treadle pumps are in common use; all three use the cylinder and paddle concept, but the model which uses a cylinder 8.9 cm in diameter and has bamboo paddles is the one most commonly favoured by farmers in the region. It is cheaper and can lift more water than a comparable hand pump. On average, a treadle pump can be used to lift water from about 6 m underground and one such pump can irrigate as much as 0.34 ha of land (depending on the soil type and other conditions). In addition to lifting water for irrigation, the treadle pump can also be used for a variety of domestic purposes. In the Terai areas of Nepal, it is also widely used as a means of generating income.
When farmers consider installing a treadle pump, they first need to verify whether there is sufficient groundwater to merit the expense. Treadle pumps should be installed by trained technicians and properly maintained throughout their lifetime. If possible, an extra set of spare parts should always be kept on hand and a trained technician should be consulted for major repairs.

编制者或其他关键资源人员认为的弱点/缺点/风险	如何克服它们？
Requires manpower. It irrigates only a limited area.	Continue research and development to make it even simpler to use, possibly even by those who are not so physically fit.
Requires continuous inspection and maintenance and a supply of spare parts (washer, check valve, bamboo poles)	Continue research and development to make it even more robust without the need for vigilant maintenance.
Over time, the pumps pump less water, there is frothing, and sand is also lifted	The joints and sockets need tightening. The right place should be selected for boring and, after installation; the area needs to be packed with gravel.
At times the pump has trouble lifting water, it is not working properly	Check the treadle frame installation. Check that the size of the washer is appropriate.
