【Product Advantages】

The system joints and pipelines are made of ultra-high pressure stainless steel joints and high-pressure seamless stainless steel pipes to ensure the security of the system, and the whole system pipeline is non welded;
System pressurization rate control and display: Agree on pressurization rate and upper limit of test piece pressure, record and draw pressure-time curve during loading, resolution accuracy: pressure 0.001MPa/index, time 1s/index; The rate resolution at the intersection point of horizontal and vertical is less than 0.001MPa/s;
For the selection of gas driven pump, the system adopts low-friction high-flow rate gas driven booster pump, which reduces the dead zone when the gas driven pump starts, the rapid reversal of the pump realizes continuous pressurization;
The automatic collection and processing function of test data can automatically establish the test database, which can be queried at any time, the data can be stored for a long time. It can display test curves and parameters in real time, store and record test results, such as burst peak value, test pressure, etc., and export the stored data in Office document format. It has the function of printing the test report and test pressure curve after the test is completed, and the test report can be edited freely;

【Control System】

Mainly including gas-liquid proportional control system, sensing control system, electrical control system and control software system, etc.

Gas-liquid proportional control system: The gas-liquid proportional control system can run for a long time, continuously, securely and stably, which can fully meet the requirements of test.
Sensing control system: The test system adopts pressure sensor and controller. Collect the pressure of the test and the medium, and control the actuator based on the collected information.
Electrical control system: The electrical control system consists of strong electricity control system and weak electricity control system.
