Problems solved by technology

[0003] At present, test benches for hydraulic components such as oil pumps and servo valves with high automation and intelligence have been developed at home and abroad, but most of them have single functions.
At the same time, there is no high-precision, automated, and fully-functional test equipment specially designed for proportional valve performance testing in China. Therefore, designing a comprehensive performance test bench for proportional valves with high practicability, reliable performance, complete functions, and high cost performance will help improve the proportion. The level of valve performance matters

Abstract

The invention provides a comprehensive property test board for an electrical modulation flow control valve, including an energy pumping station, a test board body and a test system. The energy pumping station is internally provided with three groups of oil pumps of different specifications for supplying oil to the system, and the flows of two of the three groups of oil pimps are adjusted by the rotation speed of a servo motor to meet test requirements of tested proportioning valves of different specifications. The test board body comprises a dynamic test loop and a static test loop, wherein the dynamic test loop obtains dynamic performance of the tested proportioning valves, and the static test loop obtains static performance of the tested proportioning valves. The test system is used for processing data transmitted by the tested proportioning valves to obtain parameter curves of the tested proportioning valves.

Description

technical field [0001] The invention relates to a testing technology for hydraulic components, in particular to a comprehensive performance testing platform for electric modulation flow control valves. Background technique [0002] The electric modulation flow control valve is the key hydraulic component in the electro-hydraulic proportional control. It is a hydraulic control valve that can control the pressure, flow and direction of the working oil in proportion according to the input electrical signal. Compared with on-off valves, electric modulation flow control valves can carry out long-distance, high-precision continuous control, and have compound functions, which can simplify the hydraulic system by using one valve for multiple purposes. While obtaining high-performance control capability, the electronically modulated flow control valve also has the advantages of simple structure, low processing accuracy requirements, low cost, reliable operation, and good pollution re...
