A.2 Functions and features
The control components use servo motors and imported torque sensors to control the opening and closing of the valve, with small inertial impact and stable control;
Microcomputer is used to control the test process, and the pressure-time curve, test pressure and other values are displayed in real time. The test results can be automatically saved or printed out, and the test results can be automatically saved after power failure;
Computer data acquisition and processing, printing out environment/medium temperature, cycle number and cycle pressure waveform;
The opening and closing torque stroke of the cylinder valve can be set;
You can freely set the requirements for the number of operating cycles during the test, and the test can be automatically stopped when the requirements are met;
It has a power-down protection function. After a power outage, the system automatically relieves pressure and terminates the test to maximize the safety of operators and equipment;
The leakage of the specimen can be a set alarm point. When the leakage reaches a certain level, the system will automatically alarm and stop working, and the computer will still maintain power supply.
