柱塞偶件磨损对喷油泵供油特性的影响

Effects of Wear of Plunger Pair on Delivery Fuel Characteristic of Fuel Injection Pump

通过实验得出了柱塞偶件磨损对喷油泵供油特性的影响规律。柱塞磨损使循环供油量减少，并且由于柱塞头部的节流作用，随着转速的降低，柱塞磨损的影响愈严重。

The effects of the wear of plunger pair on delivery fuel characteristic of fuel injection pump is investigated. The quantity of fuel delivering reduces with the wear of plunger pair and this tendeucy is more serious with reducing of pump speed due to the choking effect of plunger head restricting.
