Embodiment Construction

[0018] The present invention will be further described below in conjunction with drawings and embodiments.

[0019] Such as figure 1 , The test bench test circuit adopts a new type of plunger motor pump unit 1, which is small in size, small in pressure pulsation and low in noise. Cooperating with the supercharger 12, it can meet the pressure and flow requirements of most tests. When a large test flow rate is required, the existing high-flow emulsion pump source is externally connected. Equipped with a suction pump l0, the emulsion in the water tank 4 of this station is sent to the large flow pump source water tank. The liquid suction pump can also be used as the circulating pump of the water tank for cooling and filtering.

[0020] The test bench provides four liquid ports A, B, T, and X, which are respectively connected to the liquid inlet, liquid outlet and control port of the test piece. The electro-hydraulic reversing valve 9 cooperates with the hydraulic control check...

Abstract

A valve testing stand for a hydraulic support is provided, the system hardware employs the modularization design. The whole system comprises five modules consisting of a testing stand support, an emulsion station, an oil pressure station, a supercharger set and a computer table. Each module can be integrally hoisted, is compact in structure and facilitates transportation and installation. On the basis of the prior art, the loops are properly reduced, and the configuration is changed to satisfy the requirement of different users on the testing stand functions and levels. The valve testing stand for the hydraulic support has a high promotional value and is wide in the market prospect.

Description

technical field [0001] The invention relates to a valve test bench for a hydraulic support, which is suitable for the mechanical field. Background technique [0002] Hydraulic test benches have been widely used at home and abroad for a long time. There are many types of hydraulic test benches used for performance testing of emulsion valves. Generally, the maximum working pressure of the test does not exceed 40MPa. Moreover, most The test object is a single test with a single valve, usually with an emulsion pump plus a pressure regulating valve. Now with the development of technology, the requirements for the working pressure and safety performance of the emulsion valve are getting higher and higher. Now the highest can reach about 63Mpa, but the comprehensive test bench of the emulsion pump plus the pressure regulating valve can no longer realize the test of high pressure and large flow. The reason is that the maximum working pressure of the current emulsion pump is only abo...
