High-flow rate hydraulic control check valve performance testing system

Abstract

The invention discloses a high-flow rate hydraulic control check valve performance testing system. The system comprises a signal acquiring unit, a signal processing unit and a data storing and displaying unit, wherein the signal acquiring unit is used for acquiring a pressure signal and a flow rate signal in the testing system and outputting the acquired information to the signal processing unit; the signal processing unit is connected with the signal acquiring unit and is used for receiving and processing the acquired information and outputting the processed information to the data storing and displaying unit; the data storing and displaying unit is connected with the signal processing unit and is used for receiving, storing and displaying the processed information output by the signal processing unit. The system has the following characteristics of suitability for measuring performance of a high-flow rate hydraulic control check valve, high automation degree due to the fact that a mechanical, electric and hydraulic integrated design is adopted, high measuring precision, high sensitivity, stable and reliable testing performance, stable testing process and long service life of the system.

Description

technical field [0001] The invention belongs to the technical field of measurement and testing, and relates to a testing system, in particular to a performance testing system of a large-flow hydraulic control check valve. Background technique [0002] Comprehensive mechanized coal mining technology is an efficient and safe coal mining method. Since the birth of the first fully-mechanized mining face in the UK in 1954, fully-mechanized mining technology has been continuously developed and improved, and has been widely used in the world, becoming the direction of coal industry technology development. The components of a complete set of fully mechanized mining equipment can be roughly divided into support equipment, coal mining equipment and transportation equipment. Hydraulic support is one of the key equipment of supporting equipment, accounting for about 70% of the investment in fully mechanized mining face. During coal mining, many hydraulic supports are arranged in a row...

Problems solved by technology

In order to improve and optimize the dynamic performance of hydraulically controlled check valves for hydraulic supports, researchers have made various improvements to hydraulically controlled check valves for hydraulic supports. The commonly used common hydraulic control check valve test system cannot simulate the environment when the hydraulic support is in motion, which affects the test results of dynamic performance.
