评定油泵、油马达寿命的方法虽然还没有能标准化,但可以从以下三个主要方面去考虑。1.容积效率的下降率例如把容积效率降低10％所需的运转时间作为寿命判定的依据。这对于叶片泵,可以说是很容易理解的,也是合理的。2.零部件的磨损量也有把零部件磨损到某种程度的运转时间作为油泵、油马达判定寿命的方法。可是,这个方法对于在实际运转中的元件来说,可以说并不是很好的办法,最终还是要把磨损量换算成容积效率。
Although the methods used to assess the life of oil pumps and oil motors have not been standardized, they can be considered in the following three main areas. 1. Rate of decline in volumetric efficiency For example, the operating time required to reduce the volumetric efficiency by 10% is used as the basis for life determination. This is a vane pump, it can be said is very easy to understand, but also reasonable. 2. Parts wear There are parts wear and tear to some extent running time as a pump, oil motor to determine the life expectancy. However, this method can not be said to be a very good solution to the actual running components, and eventually the wear volume is converted into the volumetric efficiency.
