Abstract

The invention provides a hydraulic pump comprehensive test system. The hydraulic pump comprehensive test system comprises a main oil tank; the main oil tank communicates with a cooling circulation loop, and further communicates with a series pump set; the series pump set communicates with an oil drainage loop, a first test loop, a second test loop and a third test loop; the second test loop communicates with an oil supplementing loop and a control loop; and the oil supplementing loop and the control loop both communicate with the main oil tank. The hydraulic pump comprehensive test system meets the performance test of a high-flow pump, can realize the automatic loading, meets the load simulation condition test of a high-displacement pump, can further realize the series pump test, meets theperformance test of a triple pump at most, and meets the automatic loading and load simulation condition test of s series pump at the same time.

Description

technical field [0001] The invention relates to the technical field of hydraulic pump performance testing, in particular to a hydraulic pump comprehensive testing system. Background technique [0002] The hydraulic pump is the core component of the hydraulic system, which is mainly driven by a motor or an engine. The conventional hydraulic pump test bench adopts a single test system. A single test system. An open hydraulic pump test system is disclosed in the patent application number "201410809156.45" and the patent name "Open Hydraulic Pump Comprehensive Test System". The patent application number is "201410808879.2", the patent name is A performance test of a closed hydraulic pump is disclosed in the "Closed Hydraulic Pump Performance Test System". None of the above comparison documents can perform performance tests of multiple connection modes of serial pumps, and the domestic R&D technology of large displacement hydraulic pumps is backward. , resulting in a blank test ...
