工程机械柴油机喷油泵柱塞弹簧断裂现象时有发生,很多维修人员在维修中会将喷油泵从发动机拆卸下来进行更换。这样更换柱塞弹簧后要校对喷油泵各柱塞的喷油量,安装喷油泵时要校对喷油时间,即费时又费力。现介绍1种在柴油机上更换柱塞弹簧的方法,该方法适用于国产Ⅰ、Ⅱ、Ⅲ号系列喷油泵,及无锡威孚4Ⅰ44-75型喷油泵,这些喷油泵均为上、下分体式喷油泵。首先,将喷油泵高压管从接头上拆卸下来,并将喷油泵侧盖拆掉;其次,
Construction machinery Diesel fuel pump plunger spring breakage occurs from time to time, many maintenance personnel in the maintenance of the fuel pump will be removed from the engine to be replaced. This replacement plunger spring to proofing the fuel injection pump plunger, injection pump installed to proofing injection time, that is time-consuming and laborious. Now introduced a method of replacing the plunger spring on a diesel engine, the method is suitable for domestic series Ⅰ, Ⅱ, Ⅲ injection pump, and Wuxi Weifu 4 Ⅰ 44-75 injection pump, these injection pumps are up and down split Fuel injection pump. First, the fuel injection pump high pressure pipe removed from the connector, and the fuel pump side cover removed; Second,
