Computer valve test bench with three brief SF-3 computers spool automatic test bench is an advantage Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City Comprehensive other domestic manufacturers of similar test rig, the improvement on the original SF-II series, based on the innovation, development A more suitable for a new product with three valves manufacturers and three valves maintenance organization use. The test rig using piece valve operation 3.5 m split column machine, high speed, high efficiency, and can complete a number of tests with three valves must do. The device selected strain gauge pressure sensor stability, high accuracy. Through computer control, can be digitally set pressure display histograms and pressure changes instantly displays graphs; test results are automatically stored, query functions under many conditions, the maintenance records or report printing. Advanced Computer spool automatic test bench performance, suspension strut according to user requirements demolition column machine for 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 three valves split column machine, increase economic efficiency; improving the quality of underground prop, mine production safety will be guaranteed special equipment.
