Operation precautions and troubleshooting methods of pressure testing machine
Compression testing machine, also known as electronic pressure testing machine, is mainly used to test various physical and mechanical properties of rubber, plastic plates, pipes, profiles, plastic films, wires and cables, waterproof coils, metal wires, cartons and other materials. How much do you know about the pressure tester? The following will introduce in detail the operation precautions and troubleshooting methods of the pressure tester. Let's take a look.
1. Precautions for the use of test press
1. Frequently check whether the upper and lower limit nuts of the micro switch are loose. If they are loose, they should be adjusted in time.
2. In daily use, do not damage the parts of the back door of the control box.
3. In the process of pressure test with the test press, first confirm the direction of tension and compression, and confirm whether the indicating pressure and the pull switch or signal light are correct.
4. The testing machine should be installed in a clean, dry, non-vibrating, and non-corrosive gas room. It should not be placed in a place with high humidity to avoid damage to accuracy.
5. Check the tightness of the chain every six months.
6. In the daily use of the testing machine, be careful not to overload or subject the load components to heavy blows to ensure the accuracy of the testing machine.
7. The testing machine should be operated or supervised by a dedicated person to ensure safety.
2. Troubleshooting method of pressure testing machine
1. The transmitter wiring is incorrect, the power supply voltage is too high or too low, indicating that the connection between the indicator and the meter terminal is bad.
2. The primary components (orifice plate, telemetry connector, etc.) are blocked or installed improperly, and the pressure point is unreasonable.
3. The installation does not strictly follow the technical requirements, and the installation method and site environment do not meet the technical requirements.
4. Leakage or blockage of the pulse tube, residual gas in the filling tube or residual liquid in the filling tube, deposited in the flange during the transmitter process, forming a measurement dead zone.
5. After careful inspection, use and install in strict accordance with the technical requirements, and take effective measures in time.
6. For faults that cannot be handled, the transmitter should be sent to the laboratory or the manufacturer for further inspection.
The above is an introduction to the operation precautions and troubleshooting methods of the test press. In short, you should always pay attention to the problems found when using the test machine and eliminate them in time to avoid errors in your test results. In order to ensure the normal use of the testing machine, the testing machine must be checked and calibrated regularly. Hope to help you.
