农用柴油机以及拖拉机变型运输机在农业生产资料的运输、农副产品的产后运输,以及农村集镇的交通运输等方面起着越来越大的作用。柴油机喷油泵工作的好坏直接影响拖拉机变型运输机的动力性、经济性及环境保护性能。因此,介绍一些喷油泵的原理及常见故障的分析排除显得非常重要。 1.常用柴油机喷油泵简介目前常见的农用柴油机和变型运输机喷油泵有柱塞泵和分配泵两种。柱塞泵有国产系列泵和德国博世(BOSCH)系列泵之分。按柱塞直径及凸轮升程大小
Agricultural diesel engines and tractor variant conveyors play an increasingly important role in the transport of agricultural means of production, the post-production transport of agricultural and sideline products, and the transport of rural markets. Diesel fuel pump work directly affect the performance of tractor variant transporter, economy and environmental protection performance. Therefore, it is very important to introduce the principle of some fuel injection pumps and analyze and eliminate common faults. 1. Common Diesel Fuel Injection Pump Introduction Commonly used agricultural diesel engine and variant transport pump plunger pump and dispensing pump two. Piston pump has a series of domestic pumps and Germany Bosch (BOSCH) series of pump points. By plunger diameter and the size of the cam lift
