The invention belongs to the technical field of testing equipment for hydraulic elements and discloses a contamination-wearing and contamination-clamping test bed for a hydraulic directional valve, which comprises an oil tank, a contamination-particle injecting device, a dosing pump, a driving device and a tested-valve system, wherein the oil tank is connected with the contamination-particle injecting device and the dosing pump, the dosing pump is connected with the driving device, is also sequentially connected with a tested-valve front flow sensor, a tested-valve front pressure sensor, a tested-valve front sampling valve and a temperature sensor, is then connected with the tested-valve system, is then sequentially connected with a tested-valve rear pressure sensor, a tested-valve rear flow sensor and a tested-valve rear sampling valve and is finally connected to the oil tank through a loop, and the whole test bed is monitored and controlled through a console. The test bed can be used for measuring the contamination-wearing leakage and the contamination-clamping force of the hydraulic directional valves with different valve cores under different working conditions, and automation is realized, so that the defects of difficult disassembly, inconvenient measurement, low precision, requirements of manual operation and the like of an existing hydraulic-valve test bed are overcome.
Description
technical field [0001] The invention relates to a hydraulic component pollution test bench, in particular to a hydraulic reversing valve pollution wear and pollution clamping test bench, which belongs to the technical field of hydraulic component test equipment. Background technique [0002] As an important component of the hydraulic system, the hydraulic reversing valve has a great influence on the performance of the entire hydraulic system. Due to the pollution in the oil in the actual hydraulic system, the performance of the hydraulic reversing valve is reduced or even fails. Contamination failure of hydraulic reversing valve can be divided into two types: wear failure and clamping failure. Wearing failure can usually be characterized by leakage and surface morphology, while clamping failure can usually be characterized by clamping force. Due to the complicated steps, long cycle and many testing items of the hydraulic reversing valve pollution test, the traditional pollu...
