手扶配套的7FS-0.75型水粪车,利用发动机进气将水粪吸入粪罐,吸粪快。但由于发动机工作时缺氧,燃烧不完全,积碳多;燃烧室压力低,有烧机油现象;再就是安全阀一旦失效,粪水有吸入气缸引起炸裂的危险。因此,我们对它进行了改革,改进气吸粪为排气吸粪(见图1、2),受蓟用户欢迎。具体改进如下:1.选用195柴油机水泵机组实现水泵无底阀抽水用的引射器(实为气体射流泵,我省江津县农机一厂生产),作为对粪罐的抽气装置。2.将
Hand-supported 7FS-0.75-type water truck, the use of engine intake into the manure into water manure, suction dung fast. However, due to lack of oxygen during the engine work, incomplete combustion, more carbon deposition; combustion chamber pressure is low, the phenomenon of burning oil; then the safety valve once failure, manure suction cylinder risk of burst. Therefore, we have carried out reforms on it to improve the suction of manure to exhaust manure (see Figure 1, 2), welcomed by thistle users. Specific improvements are as follows: 1. The use of 195 diesel engine pump units to achieve the pump without bottom valve ejector (actually gas jet pump, Jiangjin County, a farm machinery factory production), as the manure tank exhaust device. 2 will be
