我厂目前使用的齿轮油泵,大部份都是旧型号——HY01型(01型),其结构见附图。这种齿轮油泵存在一个共同的质量问题,就是轴颈部份漏油。我们对这种油泵进行了分析,发现这种漏油不是元件质量造成,也不是加工或装配质量问题,而是设计结构造成的。这种油泵在解决漏油问题时,仅注意了防堵,忽视了疏通。因而不管新出厂 Gear pumps currently used in our plant, most of them are the old model - HY01 type (01 type), the structure shown in the drawings. There is a common quality problem with this kind of gear pump, that is, part of the journal oil leakage. We analyzed this pump and found that this oil spill is not caused by the quality of the component, nor the quality of the process or assembly, but the result of the design of the structure. This pump to solve the problem of oil spills, only pay attention to prevent blocking, neglected to clear. So regardless of the new factory
