Technical features of three-valve automation test bench

FZT-2Z type three-valve automatic test bench is a high-tech product integrating mechanical, hydraulic, electronic and computer technologies. It has the characteristics of reasonable structure, perfect function, easy operation and high degree of automation. It is widely used in high and low pressure sealing tests of single hydraulic prop three-way valves, working pressure setting of safety valves, determination of opening pressure and closing pressure. In addition, pressurization tests can also be performed on pillars, manometers, fittings, and the like.

The test stand consists of a loading and unloading system, a pressure regulating system, an oil pressure system, an emulsion system, and a computer measurement and control system. The loading and unloading system can be used for automatic loading and unloading of the three-way valve; the pressure regulating system can automatically adjust the safety valve pressure under the control of the computer; the hydraulic system drives the pressurized cylinder to pressurize the emulsion to the pressure required for the three-way valve test; emulsification Liquid system according to different test steps to the three-use valve filling, pressure relief or three-way valve pressure; computer measurement and control system will be the sensor pressure data collected for processing and analysis, and then control the movement of the movement mechanism according to the program, To achieve the purpose of automatic control of three-valve test.

Technical features:

1. Test procedures, test items and holding pressures are controlled by computers and tested according to industry standards.

2, automatically determine and display the test results, greatly improving the accuracy and reliability of the test results.

3, test parameters can be set and stored by the user as needed.

4, using hydraulic and electrical control technology, so that the three-way valve handling automation, greatly reducing the labor intensity of the staff.

5, the comprehensive use of computer control, electrical and hydraulic technology, so that the three-valve test during the process of high and low pressure switching, pressure adjustment and rapid injection and other actions can be completed automatically.

6. Closed-loop control technology is used to automatically and accurately adjust the pressure of the safety valve.

7, operating software written in Windows, friendly interface, easy to operate.

8, the test results are automatically saved, automatically generate reports, the operator can use a variety of ways to query, sort and print data.

9. Booster cylinder has automatic commutation function, no manual commutation, and the operation is more simple.

10. Automatically diagnose the fault of the triple-use valve and give a repair plan; the test result is stored for a long time, and a test file is created for the three-use valve, which is convenient for querying and printing.
