YB_1-50定量叶片泵的寿命试验是在本厂寿命试验台上进行的,试验台的液压系统简图如图1所示。该泵的寿命试验在继续中,现累计试验12000小时(额定压力为63kgf/cm~2,公称排量为50l/min,转速为960rpm)。寿命试验连续运行时间长、负载大,对试验台的耐久性和可靠性有更高的要求,试验中要注意的问题比较多,例如压力的控制、油温的控制、联轴器及其安装、电机的选择和冷却、冷却水的回收等。现就
YB_1-50 quantitative vane pump life test is carried out in the factory life test bench, hydraulic system diagram of the test bench shown in Figure 1. The pump life test continues, the cumulative test is now 12,000 hours (rated pressure of 63kgf / cm ~ 2, the nominal displacement of 50l / min, speed of 960rpm). Long service life test, long running time and heavy load, have higher requirements on the durability and reliability of the test bench. There are more problems to be noticed in the test, such as pressure control, oil temperature control, coupling and its installation , Motor selection and cooling, cooling water recovery and so on. Now
