Tai'an City (www.tahnjd.com) is a professional "roof dynamic instrument, mining intrinsically safe pressure detector, under the pressure of the hydraulic support shrinking self-recording instrument" of the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to participate in healthy competition in the market, so that "Tai Warner electromechanical" brand has a good reputation. We adhere to the "service first, customers first" principle, so Warner electromechanical won the trust of customers in the public security apparatus, establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! Computer valve test bench with three brief SF-3 computers spool automatic test bench is an advantage of Tai'an City Mechanical and Electrical Equipment Co., Warner other domestic manufacturers of similar comprehensive test bed 2.5 m split column machine, based on the original SF-II series on improvement, innovation 3.5 m split column machine, the development of a more suitable new products three valves manufacturers and three valves maintenance organization use. The test rig using piece valve, fast, efficient, able to complete a number of tests with three valves must do. The device selected strain gauge pressure sensor stability, high accuracy. Split column by computer control unit, can be digitally set pressure and pressure displays a histogram graph showing changes in real-time display; test results are automatically stored suspension strut demolition column machine, the query function under many conditions, the maintenance records or report printing. Advanced Computer spool automatic test bench performance, according to user requirements, testing three valves are controlled by microcomputer automatic timing detection and management judgment. The device can simultaneously test four with three valves, improve maintenance productivity with three valves, extending the life of the test rig. So using this equipment can reduce maintenance costs with three valves, increase economic efficiency; improving the quality of underground prop, mine production safety will be guaranteed special equipment.
