Mining motor The manufacturer explained the daily maintenance of mining motor vehicles and simple self-rescue measures after motor water ingress.
Mining motor manufacturer: Daily maintenance and upkeep of mining motor vehicles
The daily maintenance methods for mining motor vehicles are as follows:
(1) Check the chassis springs for cracks and faults, clean the dirt on the springs, and inject oil between the hinge points and the balance beam.
(2) Check the wheels for cracks, whether the tires are loose, and the degree of wear on the wheel tread.
(3) Check the wear of the brake pads, replace brake pads exceeding the wear limit; check the gap between the brake pads and the wheel tread, adjust the gap in time if it exceeds the specified range; clean the dirt on the brake shoe bolts and brake shoes.
(4) Check whether the levers and pins of the braking system are intact, whether the operation is flexible, and add oil.
(5) Check whether the pins and cotter pins of the body and various bolts are complete, whether the bolts are tightened, and whether the connection between the pins and cotter pins is good, especially the device for hanging the traction motor should be carefully checked.
Mining motor Manufacturer: Installation precautions for explosion-proof motors
Explosion-proof motors are motors that can be used in flammable and explosive factories. They are mainly used in coal, petroleum, natural gas, and other chemical industries because they do not produce electric sparks during operation. In addition, explosion-proof motors are also widely used in textiles, transportation, papermaking, and pharmaceuticals.
With the development of society and technological progress, there is still a risk of explosion. Therefore, explosion-proof motors are widely used, but some people still do not attach importance to explosion. When installing, please use explosion-proof motors. Today, we will remind you of the precautions during use. I hope all friends will pay attention to it.
Before installing the explosion-proof motor, it is necessary to strictly check the basic application of the motor according to the motor regulations. The selection of the motor and related electrical equipment must strictly comply with the design requirements, and check whether there is an explosion-proof certificate and explosion-proof mark.
Mining motor manufacturer: Simple rescue measures after motor water ingress
A user consulted, when using the motor, water accidentally entered the water, what should I do? Today, the medium-sized motor tells you simple measures.
First, remove the motor fan cover. If a pulley is installed, remove the impeller after removing it (if no pulley is installed, remove it from the rear cover), tighten the 6 or 8 bolts on the top cover, remove the motor bearing end cover and terminal cover, and pull out the rotor; then erect the stator, and bake it with a 200-watt bulb in the stator hole for 2 hours. Remember to cover the top of the stator appropriately during baking to prevent the stator from dissipating heat too quickly, keeping it at 80~100. The insulation resistance measured by the megohmmeter is 5mΩ.
Try not to damage the enamelled wire during disassembly. If the insulation layer of the enamelled wire is damaged, you can go to a store selling enamelled wire to bake it dry. There is also the problem of bearings. If you clean bearings without dust covers with kerosene or diesel oil, add appropriate calcium-based grease. If bearings with dust covers can be baked at 80~100°C for two hours, you can also place the bulb underneath when baking the stator, gently press the bearing on the bulb together, and then clean the debris inside the motor housing and end cover, and gradually reinstall it. After completion, conduct a no-load test, and only use it after confirming that there are no abnormalities.
Mining motor The manufacturer's explanation ends here today. Thank you for watching.
