Engineering machinery multi-way valve performance test bench and test method
The invention discloses an engineering machinery multi-way valve performance test bench and a test method, and the test bench comprises a pilot oil supply unit comprising a first electromagnetic overflow valve and an electromagnetic reversing valve, a plurality of main power units comprising a second variable frequency motor and a high-pressure overflow valve, and a plurality of analog loading units comprising a one-way valve and a second electromagnetic overflow valve. The control end can control the electromagnetic relief valve I, the high-pressure relief valve, the electromagnetic relief valve II, the electromagnetic reversing valve and the variable frequency motor II; the tested multi-way valve comprises a plurality of ports, Pi is communicated with the main power unit, and T is communicated with the oil tank; the port Aj and the port Bj are working oil ports of the tested multi-way valve, and the port Aj and the port Bj are respectively communicated with a hydraulic bridge circuit of the analog loading unit; the XDA and the XDB are communicated with the electromagnetic reversing valve, and the moving direction of a valve element of the tested multi-way valve is controlled through reversing. The multi-way valve single-linkage working performance test and the multi-linkage composite working condition working performance test can be realized, and meanwhile, the actual working condition of the excavator can be truly simulated.
本发明公开了一种工程机械多路阀性能试验台架及试验方法，包括：包含电磁溢流阀一、电磁换向阀的先导供油单元，包含变频电机二、高压溢流阀的若干个主动力单元，包含单向阀和电磁溢流阀二的若干个模拟加载单元，能控制电磁溢流阀一、高压溢流阀、电磁溢流阀二、电磁换向阀、变频电机二的控制端；被试多路阀包括多个端口，Pi与主动力单元连通，T与油箱连通；Aj和Bj为被试多路阀的工作油口，Aj端口和Bj端口分别与模拟加载单元的液压桥路连通；XDA和XDB与电磁换向阀连通，通过换向控制被试多路阀的阀芯移动方向。本发明能实现对多路阀单联工作性能的测试和对多联复合工况工作性能的测试，同时能真实地模拟挖掘机的实际工况。
