Abstract

The invention discloses a device for testing the performance of a hydraulic multiway valve. The device comprises a plurality of three-way valves. With different combinations of the three-way valves, a plurality of working modes of each functional valve can be realized; and a sensor is utilized to test, so that the device is complete in testing function. In addition, a pressure signal subtracter is provided, so that pressure signals of two corresponding sensors can be received. As the number of signal channels can be reduced effectively, the effects of cost reduction, installation convenience, heating uneasiness and the like are achieved.

Description

technical field [0001] The invention relates to the field of hydraulic multi-way valves of excavators, in particular to a device for testing the performance of hydraulic multi-way valves of excavators. Background technique [0002] As an efficient earth-rock construction machine, hydraulic excavators occupy an important position in the construction machinery industry. [0003] The multi-way valve is the core component in the hydraulic system of the excavator, which is used to operate and control the movement of various parts of the excavator. The performance of the multi-way main valve is related to various operations and controls of the excavator, and directly affects the technical performance and quality of the excavator. [0004] In the prior art, the multi-way valve test is usually performed statically on a hydraulic component test bench. The applicant conducted in-depth research on this and found that a defect of the existing test method is that this method cannot tes...
