迅速发展农业是当前我国經济建設中的首要任务,而提高农业劳动生产率,加速农业机械化,又是我国农业发展中的一个极其重要的問題。我国农业机械的生产,虽然已經有了很快的增长,但还远不能滿足我国广大农村的需要。一般說来,农业机械中以动力机械最为重要,而排灌机械又在其中占有很大的比重。我国农村当前迫切需要的是結构簡单、制造容易、运行及維护方便的动力排灌机械。从原理上分析,并从实际試驗的情况来看,內燃水泵是有条件成为这样的一种排灌机械的。內燃水泵的基本原理是:用一个往复摆动的管中水柱来代替內燃机中的活塞、連杆、曲軸和飞輪,使燃烧气体的压力直接作用在水面上,将水压到高处。水柱前行的慣性,造成气缸和进水閥处的低压,使可燃气体或 The rapid development of agriculture is the primary task of our country’s economic construction. Improving agricultural labor productivity and accelerating agricultural mechanization are yet another extremely important issue in the agricultural development of our country. Although the production of agricultural machinery in our country has been growing rapidly, it still can not meet the needs of vast rural areas in our country. In general, the most important agricultural machinery to power machinery, irrigation and drainage machinery in which they account for a large proportion. What we urgently need in the countryside of our country are the power drainage and irrigation machinery with simple structure, easy manufacture, convenient operation and maintenance. From the principle analysis, and from the actual test situation, the internal combustion pump is a condition to become such a drainage and irrigation machinery. The basic principle of the internal combustion pump is: replace the piston, connecting rod, crankshaft and flywheel in the internal combustion engine with a reciprocating water tube, so that the pressure of the combustion gas directly on the water, the water pressure to a high place. The inertia of the water column moves forward, causing low pressure at the cylinder and inlet valves to make it combustible
