Rotating equipment inspection
Thread Content
After the equipment arrives at the factory, is there any way to check the material inside the rotating parts of the equipment?
Do you mean the overcurrent component? Manufacturers generally don’t dare to use materials carelessly; the working conditions on site don’t allow the use of just any material, and they would still have to bear the costs if something goes wrong during the warranty period. If you’re really worried, the only option is to take it apart and check what materials are used:lol
Generally, the material of the components subject to overcurrent is not tested; corrosion and wear are checked during use
To actually conduct a test, the device has to be disassembled. If problems arise after it’s taken apart and then reassembled, it will be difficult to determine who is responsible.
Negotiate with the supplier; it’s possible to conduct a random inspection of one unit, and PMI can check the materials, which is very convenient
Ask the supplier to come on site and guide the disassembly and inspection. Witness the test results at the same time.
It can be simply verified by testing the hardness of the material surface (end face)
