Embodiment Construction

[0020] Such as figure 1 As shown, the open hydraulic pump comprehensive test system of the present invention includes a main oil tank 100 , a self-priming oil circuit 200 , a first test oil circuit 400 , an oil drain circuit 600 and a control oil circuit 700 .

[0021] The self-priming oil circuit 200 includes an electric ball valve D3, a first cut-off valve K4, a first temperature sensor W4, and a first pressure sensor P4. The main oil tank 100 is connected to the electric ball valve D3, and the electric ball valve D3 is connected to the first stop valve K4, and the first stop valve K4 is connected to the first main oil port of the product pump under test. The first temperature sensor W and the first pressure sensor P4 are installed on the self-priming oil passage 200 between the first cut-off valve K4 and the main oil tank 100 .

[0022] The first test oil circuit 400 includes an oil return filter G1, a first flow meter L2, a second stop valve K2, a second temperature senso...

Abstract

The invention discloses an open type hydraulic pump comprehensive testing system which comprises a main oil tank, a self-absorption oil way, a first test oil way, a drainage oil way, a control oil way and a first X-port control oil way. The self-absorption oil way comprises an electric ball valve, a first stop valve, a first temperature sensor and a first pressure sensor. The main oil tank is connected with the electric ball valve, the electric ball valve is then connected with the first stop valve, the first stop valve is then connected to a first main oil port of a tested product pump, and the first temperature sensor and the first pressure sensor are installed at the position, between the first stop valve and the main oil tank, on the self-absorption oil way. By means of the open type hydraulic pump comprehensive testing system, the flow, the pressure and the temperature of an open type hydraulic pump in the operation process can be tested, impact, forward rotating and reverse rotating tests can also be conducted on the hydraulic product pump, and even performance tests of hydraulic products under the situation of X-port control can be simulated. Thus, the open type hydraulic pump comprehensive testing system has the advantages of being wide in test application, convenient to operate and the like.

Description

technical field [0001] The invention belongs to the technical field of hydraulic product testing, and relates to an open hydraulic pump comprehensive testing system. Background technique [0002] The hydraulic pump is the power component of the hydraulic system. It is driven by an engine or an electric motor. It sucks oil from the hydraulic oil tank, forms pressure oil and discharges it, and sends it to the actuator. After the hydraulic pump is manufactured, it is necessary to test the working performance of the pump, such as testing the pressure, temperature, flow rate and performance of the oil circuit under impact and square rotation. For the swash plate type plunger variable pump, it is also necessary to test the change of the flow rate of the pump through the X port. However, the current test system is difficult to meet the above requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an open hydraul...
