1. Break the main power supply, hang the signboard, and review whether the motor ground wire is good.
2. First of all, we adjust the tightness of the belt of the fire foam fan, and use the hand disk to use the wind wheel to see if the change is stable.
3. Add skid oil to the transition site to quasilate the sensitivity of the joint bearing and rolling bearings.
4. The case of the housing paint should be replenished.
5. View whether the opening and closing movements of the 3C fire valve are reliable and sensitive.
6. View the pads and sealing fillers between the joint surfaces and the conversion.
7. Manually turn on the indicator light, current, voltage meter operation, check whether they are normal, and check whether the various components of the fan have different sounds, and whether the three -phase current value is balanced.
