油泵的有效寿命是与安装状况、使用材料、工作油以及运转条件直接相关。油泵在指定条件下,以排出流量达不到规定值时作为油泵的寿命。这是由于机械干扰或材料应力过大而引起损伤,或者也由于磨损过程的积累影响而造成的。油泵内部磨损的速度与油泵的工作油污染浓度成正比。这情况随着使用工作油的种类以及混入油中的污染物的量和质不同而有差异。另一方面,由于油泵的狭小间隙(泄漏油路)表面的磨损,而导致排出量减少。油泵的
The effective life of a pump is directly related to the installation conditions, materials used, working oil and operating conditions. Pump under specified conditions, to discharge the flow rate of less than the specified value as the life of the pump. This is due to mechanical interference or material stress caused by damage, or also due to the accumulation of wear and tear caused by the process. The internal pump wear speed and oil pump oil concentration is proportional to pollution. This situation varies depending on the type of working oil used and the amount and quality of the contaminants mixed into the oil. On the other hand, the discharge amount is reduced due to the wear of the surface of the oil pump on the small clearance (leakage oil passage). Oil pump
