一台抽水机是由两部分组成的:一部分是用来把水提升上来的机器,叫水泵;另一部分是用来拖动水泵的机器,叫动力机。它们一般是用皮带连接起来的。(见图1)农村里用来车水的动力机有以下几种:1.烧煤、木炭、泥炭、木柴、稻壳……等固体燃料的煤气机,是目前农村中最常用的。把燃料放在一种特制的炉子里燃烧,就会产生一种可以燃烧的气体,叫煤气。再把煤气送到发动机的气缸里燃烧爆炸,就会使曲轴旋转,来替我们工作。如果本地或附近地区出产煤、炭、稻壳、泥 A pump is composed of two parts: one is the machine used to lift the water, called the pump; the other part is used to drag the pump machine, called the power machine. They are usually connected by a belt. (See Figure 1) There are several power machines used in rural areas for car water: 1. Gas engines such as coal, charcoal, peat, firewood, rice hulls, and other solid fuels are the most commonly used in rural areas. Putting the fuel in a special stove and burning it produces a gas that can burn, called gas. Then the gas sent to the engine cylinder combustion explosion, it will make the crankshaft rotation, to work for us. If the local or nearby areas produce coal, charcoal, rice husk, mud
