Embodiment Construction

[0015] exist Figure 1~5 Among them, No. 1 tested hydraulic pump 1, No. 1 torque tachometer 2, motor 3, and No. 6 tested hydraulic motor 4 are coaxially connected through couplings to form power and power recovery system module A; No. 1 flowmeter 5, No. 2 flowmeter 6 and No. 3 flowmeter 7 respectively measure the leakage flow rate of No. 1 tested hydraulic pump 1 and the oil return flow rate and leakage flow rate of No. 6 tested hydraulic motor 4 . When the test device is started, the motor 3 drives the No. 1 tested hydraulic pump 1 to rotate, and the No. 1 tested hydraulic pump 1 drives the No. 2 tested hydraulic motor 10 to rotate. The pipeline between the two is connected with the No. 1 pressure sensor 8, 1 No. temperature sensor 9 is used to test the working pressure and oil temperature between No. 1 tested hydraulic pump 1 and No. 2 tested hydraulic motor 10 respectively. No. 2 tested hydraulic motor 10, No. 2 torque tachometer 11, and No. 3 tested hydraulic pump 12 are ...

Abstract

The invention discloses a modularly-parallel, multi-machine and energy-saving reliability testing device for hydraulic pumps and hydraulic motors. The device is of a modular structure, and comprises a dynamic and power recovery system module A, at least one sample module, a loading system module C and a real-time monitoring system module D, wherein an oil inlet of a to-be-tested hydraulic pump of the dynamic and power recovery system module A is connected with an oil tank; an oil outlet of the to-be-tested hydraulic pump of the dynamic and power recovery system module A is connected with an oil inlet of a to-be-tested hydraulic motor in the first parallel sample module; an oil outlet of a to-be-tested hydraulic motor of the dynamic and power recovery system module A is connected with the oil tank; an oil inlet of the to-be-tested hydraulic motor of the dynamic and power recovery system module A is connected with a to-be-tested hydraulic pump in the last parallel sample module and the loading system module C; the to-be-tested hydraulic motor is driven by the to-be-tested hydraulic pump in the last parallel sample module. All component parts of the device are designed to be of a modular type, so that a system structure is simplified, and the device is convenient and flexible to install, and lower in space occupation; by repeatedly connecting the parallel sample modules in series, samples can be added for the reliability test of a hydraulic product with minimum cost.

Description

technical field [0001] The invention relates to a test device for reliability parameter testing of hydraulic pumps and hydraulic motors, in particular to a reliability test device for hydraulic pumps and hydraulic motors based on energy-saving power recovery technology and increased parallel sample structure. Background technique [0002] Hydraulic pumps and hydraulic motors are the core power components of the hydraulic system, and their reliability level is directly related to the reliability and safety of the entire hydraulic system. Therefore, it is very necessary to conduct reliability tests on hydraulic pumps and hydraulic motors. It is of great significance to improve the reliability level and market competitiveness of domestic hydraulic pumps to obtain their reliability parameters through reliability tests and analyze the failure mechanism. [0003] The traditional hydraulic product reliability test has the disadvantages of few samples, high energy consumption, and l...
