Maintenance techniques and performance characteristics of manhole cover pressure fatigue testing machine

The manhole cover pressure fatigue testing machine is a testing device used to measure the fatigue characteristics, fatigue life, prefabricated cracks and crack propagation tests of tensile, compression or tension-pressure alternating loads of the manhole cover at room temperature. The manhole cover pressure fatigue testing machine is a special equipment specially designed for testing manhole covers. It can check whether the manhole cover is qualified and plays an important role in ensuring traffic safety. Below, the editor will tell you about the maintenance techniques and performance characteristics of the manhole cover pressure fatigue testing machine, so that you can further understand the equipment.

1. Maintenance skills of manhole cover pressure fatigue testing machine

First of all, before I use the manhole cover pressure fatigue testing machine, I need to check whether there is anti-rust oil on the fixture. This is very important. Because our equipment is used to experiment with any material, it is inevitable that some materials will rust after contact, which will affect our next use. So we must check whether there is oil on the fixture before using it. If there is no oil, it must be added in time. If rust occurs, it must be handled in time to avoid unnecessary trouble for future work.

Second, check whether the screws of the manhole cover pressure fatigue test machine are loose. If there is looseness, it must be handled in time, otherwise it will affect the normal operation of the equipment. There is a high possibility that there will be certain safety hazards, but the data is inaccurate, let alone. So we must pay attention to checking the loose screws regularly!

Third. When we use the manhole cover fatigue testing machine, in order to avoid some abnormalities, we use a constant voltage to ensure that its power supply is normal. Otherwise, insufficient power supply will cause the equipment to automatically turn off frequently, which will affect the life of the equipment. After turning off the equipment, we also need to turn off the system controller and computer to ensure that the data in the computer is not leaked or lost.

Fourth, after using the manhole cover pressure fatigue test machine, you must remember to clean it. After my equipment works, there will definitely be some dust stains on the surface, and you just need to use a dry rag to wipe it clean. If there are stubborn stains, you can use a detergent. The dosage should not be too high, otherwise it will easily corrode the surface of the equipment.
