分配泵由于柱塞压油行程短(不到1毫米),为保证每循环一定的进油充量,泵上装有二级输油泵,该泵的作用是,把从发动机输油泵送来的燃油增压,再送往分配转子的油道中。二级输油泵由输油泵盖、偏心环、滑片转子、滑片、油封圈等零件组成(图1)。工作时,碳素滑片紧帖偏心环内表面刮动,同时在滑片转子字槽内往复滑动,极易磨损(我厂 Dispensing pump Because the plunger pressure stroke is short (less than 1 mm), in order to ensure a certain amount of charge per cycle charge, the pump is equipped with two oil pump, the role of the pump, the pump from the engine oil pump Pressurized, then sent to the distribution of rotor in the oil. Two oil pump from the pump cover, eccentric ring, vane rotor, vane, seal ring and other parts (Figure 1). At work, the carbon vane tight scraping eccentrically ring inner surface scraping, while reciprocating slide in the rotor vane slot, easy to wear (I plant
