我国对英国产DPA型分配泵的使用与维修已经做了许多卓有成效的工作,但对德国产VE型分配泵的使用与维修尚未见系统的总结。本文简述在实践中发生的一些情况,供喷油泵维修人员参考。泄油环是VE泵上的一个关键性零件,它控制喷入气缸油量的多少,与DPA型分配泵的油量控制阀(计量器)作用相似,但计量器是控制进入柱塞腔油量的多少,
China has done a lot of fruitful work on the use and maintenance of DPA-type distribution pumps made in Britain. However, there is no systematic summary on the use and maintenance of VE-type distribution pumps in Germany. This article outlines some of the conditions that occur in practice for reference by injection pump service personnel. The drain ring is a key part of the VE pump that controls how much fuel is injected into the cylinder, similar to the DPA-type dispense pump’s fuel control valve (meter), but the gauge controls the amount of oil entering the plunger cavity How much,
