Embodiment Construction

[0021] Such as figure 1 As shown, the hydraulic product 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 300, a second test oil circuit 400, a bridge circuit 500, a drain circuit 600 and a control oil circuit 700.

[0022] 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.

[0023] 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 fi...

Abstract

The invention discloses a comprehensive testing system for a hydraulic product pump. The comprehensive testing system comprises a main oil tank, a self-priming oil circuit, a first testing oil circuit, a second testing oil circuit, a bridge oil circuit, an oil release circuit, an oil control circuit and a pressure oil supply circuit. The bridge oil circuit is a closed circuit structure and formed by sequentially connecting a first one-way valve, a second one-way valve, a third one-way valve and a fourth one-way valve. A first joint, a second joint, a third joint and a fourth joint are sequentially formed between the adjacent one-way valves. The comprehensive testing system for the hydraulic product pump tests the flow, the pressure and the temperature of a hydraulic product pump in operation, can also test impact and forward / backward rotation of the hydraulic product pump, and has the advantages of being wide in testing application, convenient to operate and the like.

Description

technical field [0001] The invention belongs to the technical field of hydraulic product detection, and relates to a hydraulic product pump comprehensive test 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. 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 a comprehensive test system for hydraulic product pumps, so that various performances of hydraulic products can be tested through one test system, and o...
