Embodiment Construction

[0024] Such as figure 1 As shown, the forward and reverse impact performance test system of the closed hydraulic pump of the present invention includes a main oil tank 100, a first test oil circuit 300, a second test oil circuit 400, a bridge circuit 500, a drain circuit 600 and a control oil circuit 700.

[0025] The bridge circuit 500 is composed of four first one-way valves F1, second one-way valve F2, third one-way valve F3, and fourth one-way valve F4 connected in sequence to form a closed circuit structure, wherein the adjacent one-way valves The first node J1, the second node J2, the third node J3, and the fourth node J4 are sequentially formed between them.

[0026] The first test oil circuit 300 includes a first flow meter L1, a first stop valve K1, a first temperature sensor W1, and a first pressure sensor P1. Wherein, one end of the first flow meter L1 is connected to the first main oil port of the product pump under test, and the other end is connected to the fir...

Abstract

The invention discloses a closed hydraulic pump forward and reverse impact performance test system, which includes a main oil tank, a first test oil circuit, a second test oil circuit, a bridge circuit, an oil drain circuit, a control oil circuit, a pressure oil supply circuit and The first X port control oil circuit; the control oil circuit includes a second relief valve, an electromagnetic reversing valve and a third relief valve; the electromagnetic reversing valve and the third relief valve are connected in series to form a shock test control oil After the impact test control sub-oil circuit and the second overflow valve are connected in parallel, one end is connected to the second node of the bridge circuit, and the other end is connected to the main oil tank. The forward and reverse impact performance test system of the closed hydraulic pump of the present invention can realize the test of the forward and reverse impact performance of the closed hydraulic pump, and can even simulate the performance test of hydraulic products under the control of the X port, and has a wide range of testing applications , Easy operation and so on.

Description

technical field [0001] The invention belongs to the technical field of hydraulic product detection, and relates to a positive and negative impact performance test system of a closed hydraulic pump. 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. The closed hydraulic pump adopts the pressure oil supply method when it is working. After the closed hydraulic pump is manufactured, it is necessary to test the forward and reverse impact performance of the pump, such as testing the pressure, temperature and flow of the oil circuit. 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 [000...
