国产丰收—4型分配式喷油泵的分配转子与分配套筒容易卡死,本文从分配泵的结构、制造和维修等方面,运用摩擦学原理,对其卡死进行分析。一、分配泵卡死的基本情况我厂1979年~1980年共修油泵11461台,其中卡死泵为1116台,卡死率为9.8%,具体情况如下: 1.卡死部位由表1可见分配转子的卡死以带内螺纹的前端1处最为严重,绝大多数在密封面前端4毫米的同一范围内,尤其是端头1毫米处,呈现有规
The distribution of the domestic bumper harvest pump-4 distribution of the rotor and the distribution sleeve is easy to die, this article from the pump structure, manufacture and maintenance, the use of tribology principles, the stuck analysis. First, the basic situation of the distribution pump stuck I plant from 1979 to 1980, a total of 11,461 sets of pumps, of which 1116 death pump card, card-killing rate of 9.8%, the specific circumstances are as follows: 1 stuck parts can be seen from Table 1 The distribution of the rotor stuck to the front end with a thread at the most serious 1, the vast majority of the sealing surface in front of 4 mm in the same range, especially at the tip of 1 mm, there are rules
