Problems solved by technology

[0002] At present, when the durability test of the hydraulic oil tank is carried out, the method of inflation simulation is used to increase the pressure in the oil tank, but because the gas is filled, it cannot reflect the change of the hydraulic oil volume in the oil tank when the hydraulic oil tank is actually working; and In this method, after the hydraulic oil tank is deflated, the minimum pressure in the oil tank is the normal atmospheric pressure, and it cannot simulate the actual working conditions, when the oil pump absorbs oil, the negative pressure in the oil tank is generated; nor can it simulate the pressure generated by the weight change of the hydraulic oil itself on the hydraulic oil tank influences

Abstract

The invention discloses a hydraulic oil tank actual working condition simulating device and a hydraulic oil tank durability test method. The hydraulic oil tank actual working condition simulating device comprises a bidirectional variable pump, a reversing valve and an oil tank; the bidirectional variable pump is correspondingly connected to an oil suction opening and an oil return opening of a hydraulic oil tank to be tested through the reversing valve; when the reversing valve is at the first position, the oil suction opening of the hydraulic oil tank to be tested communicates with the bidirectional variable pump, and the bidirectional variable pump sucks hydraulic oil from the hydraulic oil tank to be tested and is pumped into the oil tank through an oil suction pipeline; when the reversing valve is at the second position, the oil return opening of the hydraulic oil tank to be tested communicates with the bidirectional variable pump, and the bidirectional variable pump sucks the hydraulic oil from the oil tank and is pumped into the hydraulic oil tank to be tested through an oil return pipeline. Through the suction and return of the hydraulic oil, the volume change of the hydraulic oil in the hydraulic oil tank is simulated, meanwhile, the influence of the weight of the hydraulic oil on the oil tank is considered, the negative pressure condition in the oil tank is further simulated, the negative pressure condition is closer to the actual condition of the hydraulic oil tank, and the testing accuracy is ensured. The system is simple, and the testing cost is reduced.
