摘要

摘要本文介绍了调节和非调节液压泵在实验室条件下的试验。对由两个独立液压回路组成的液压装置(用于测试非调节液压泵和调节液压泵)进行了实验室试验。使用节流阀或比例节流阀进行加载。在室内试验中，转速n = 1,500 rpm(公称转速)时，非调节液压泵的流量效率η pp = 98.91% (0 MPa)和η pp = 94.97% (20 MPa)，调节液压泵的流量效率η pp = 97.57% (0 MPa)和η pp = 94.54% (20 MPa)。液压泵流量效率的测定值决定了实验液压实验室设备的正确运行。

Testing of Regulating and Non-Regulating Hydraulic Pumps

Abstract This article deals with the testing of regulating and non-regulating hydraulic pumps in laboratory conditions. The laboratory test was carried out on the hydraulic device consisting of two separate hydraulic circuits (for testing the non-regulating hydraulic pump and regulating hydraulic pump). A throttle valve or proportional throttle valve is used for loading. During the laboratory tests, the flow efficiency of the non-regulating hydraulic pump at rotation speed n = 1,500 rpm (nominal speed) was η pp = 98.91% (0 MPa) and η pp = 94.97% (20 MPa), and for the regulating hydraulic pump, the values were η pp = 97.57% (0 MPa) and η pp = 94.54% (20 MPa). The determined values of flow efficiency of hydraulic pumps determine the correct operation of the experimental hydraulic laboratory equipment.
