What should be paid attention to in the daily maintenance and maintenance of the ring stiffness testing machine?



The ring stiffness testing machine is widely used in the testing of the ring stiffness of thermoplastic pipes and FRP pipes with circular cross-sections. It meets the standards of PE double-wall corrugated pipes, winding pipes and various pipe standards, and can achieve pipe ring stiffness and ring stiffness. Tests for flexibility, flatness, bending, and weld tension.


With function keys to adjust the speed, test force displacement digital display, with peak value guarantee, damage automatic shutdown, overcurrent, overload automatic protection functions.


Next, our technical staff will introduce us the daily maintenance and working environment standards of the ring stiffness testing machine.







1. Daily maintenance of ring stiffness testing machine








1. Frequently ensure that the ring stiffness testing machine equipment and computer are clean and hygienic.








2. Prevent high temperature, excessive humidity, dust, corrosive media, water, etc. from immersing inside the machine or computer.








3. Regular maintenance and inspection to ensure the integrity of parts and components.








4. Pay special attention to the rust-prone parts or accessories that are not used for a long time, such as jigs, bolts, etc., to coat rust inhibitors.








5. The ring stiffness testing machine should ensure that the jaws of the fixture or the relative sliding surface of the fixture are clean to prevent bumps.


After making a batch of samples, the debris remaining in the jaws should be cleaned up in time. If the teeth of the jaws are blocked, please use a steel brush dipped in gasoline to clean. Avoid using hard tools for cleaning.








6. Pay special attention to applying anti-rust agent to the surface of the light bar every 3 months.








2. Working environment standard of ring stiffness testing machine








1. When the room temperature is within the range of 10 ~35 ℃, the temperature fluctuation should not exceed 2 ℃/h;








2. The relative humidity is less than 80%;








3. The change of power supply voltage should not exceed Hefei Rheumatism Hospital
±10% of rated voltage.


Power frequency 50 Hz;








4. Ring stiffness testing machine in an environment without obvious electromagnetic field interference;








5. In a level environment without shock and vibration;








6. There is no corrosive medium around;








7. There should be a space not less than 0.7m around the testing machine (with an environmental box, the space should be enlarged accordingly), and the working environment should be clean and dust-free;








8. The level of the main frame and the rack does not exceed 0.2 ‰








The operator of the instrument should carefully read and understand the maintenance of the instrument, and maintain the instrument so that the instrument is always kept clean, the parts and accessories are complete and safe, to ensure the normal operation of the instrument. In summary, the daily routine of the ring stiffness testing machine The detailed introduction of maintenance and working environment standards, I hope to help you.
