Abstract

The invention discloses a performance detection test stand for a main valve of a hydraulic excavator, belonging to a hydraulic system detection device. The performance detection test stand comprises an excavator hydraulic simulation unit, an electrical control unit, a leakage detection unit and a circulating cooling unit. The performance detection test stand has the advantages that the performance of the main valve of the hydraulic excavator can be detected all around through controlling actions of various units in an oil path through a control device; centralized processing of data can be realized through the control device, which is convenient for outputting a detection result; the manual control and the program automatic control of the main valve to be detected are realized through switching a control lever and an electromagnetic proportional valve; and the main valve to be detected and the detection test stand can be quickly and conveniently connected through a quick coupling.

Description

technical field [0001] The invention relates to a hydraulic system detection device, in particular to a hydraulic excavator main valve performance detection test bench. Background technique [0002] With the development of infrastructure, excavators and other construction machinery have been widely used in construction, water conservancy and other engineering fields. The main purpose of an excavator is to extract material from the earth's surface and transfer it to the discharge point, then transfer it back to the excavation site, and repeat. Most of the excavators currently used are hydraulic excavators, which have the advantages of flexible construction and high efficiency, so they are widely used in housing construction, water conservancy and other occasions. The hydraulic system of the excavator is mainly composed of the main pump, the main valve, the actuator, hydraulic oil and auxiliary components. The main valve is the core control component of the hydraulic system o...
