在1993年第一期“油泵油嘴技术”杂志上发表的“高速强化Ⅰ号泵的改进设计”中提到将柱塞套的定位槽由上部改为下部,这样使承受工作压力的上部刚度提高,减小了工作时的变形量,从而减少了磨损,提高了可靠性。现采用另一种方法,将普通的柱塞套上的两个进油孔改为一个进油孔,通过理论分析,各项试验以及实际使用都证实:只要设计正确,单孔柱塞偶件不仅不会影响发动机性能,而且可使可靠性等性能有明显的提高。现分下述几个方面进行论述:
In 1993, the first issue of “pump nozzle technology” magazine published “high-speed enhanced pump No. Ⅰ improved design” referred to the positioning of the plunger sleeve from the upper to the lower, so that the upper part of the work under pressure to increase the stiffness , Reducing the amount of deformation at work, thereby reducing wear and improving reliability. Now using another method, the two ordinary oil into the hole into a hole into the oil through theoretical analysis, the test and the actual use of both confirmed: as long as the design is correct, single-hole plunger coupling Not only does not affect the engine performance, but also can significantly improve the reliability of performance. Now divided into the following aspects to be discussed:
