制造柴油机油泵柱塞付元件的材料,通常用经过热处理的合金钢,被采用最多的有ХВГ和ШХ15。但是经验证明,这些钢种存在着一系列的缺点,它们往往不能保证柱塞付可靠的和经久的工作,货源缺少,而且加工困难。特别是ХВГ的冲压和锻造工艺过程非常复杂,以致一些单件生产甚至成批生产的企业宁愿采用棒材,根据产品的最大尺寸来选择制造柱塞付的棒材直径。这样,在加工过程中将会被切削去大
Materials used to make diesel pump plungers, usually heat treated alloy steels, are most commonly used as ХВГ and ШХ15. However, experience has shown that these steels have a number of shortcomings that often do not guarantee reliable and long-lasting work on plungers, lack of supply and processing difficulties. In particular, the ХВГ stamping and forging process is so complex that some single-piece or even batch-producing companies prefer to use bars for the diameter of the bar to make the plunger, based on the maximum size of the product. In this way, in the processing process will be cut to big
