plunger sleeve meaning in Chinese

柱塞套

Based on the former electronically controlled pump of our group , a new type pump has been designed and manufactured , which can implement pilot injection . the plunger , plunger sleeve and spring , as the key parts of the electronic pump , have been designed especially . and the problems in design are discussed in detail
设计、研制出实现预喷的电控喷油泵，重点是对电控泵中的关键部位一柱塞偶件，柱塞弹簧的设计，并对设计中应该注意的问题进行了较为详细的分析。
The result indicates that the method is effective on the control of initial injection rate . some different size plungers and plunger sleeves have been designed for the second time . from the test result , some conclusions have been summarized , which is used to optimize the pilot injection for matching the diesel engine
为进一步考察预喷的情况，对柱塞进行了第二轮设计，通过对多种不同预喷规格的柱塞进行试验对比，得出影响预喷效果的主要结构参数和工作参数，为以后上柴油机匹配作试验依据。
