Daily inspection and maintenance of the mine hoist motor? 1. Check: During daily inspections, check the operating condition of the pneumatic hoist motor, the magnitude and variation of the current, and see if there is any water leakage or dripping, as this can lead to insulation failure and burning of the mine hoist motor. It also depends on whether there are any objects around the hoist motor that affect its ventilation and heat dissipation environment. Check if the fan cover, fan blades, and the exterior of the mine hoist motor are dirty and need cleaning. Ensure its heat dissipation effectiveness; whoever discovers the problem should address it promptly.

1. Look: During daily inspections, check the working condition of the pneumatic winch motor, the size and variation of the current, and see if there is any water leakage or dripping, which can lead to insulation failure and burning of the winch motor. It also depends on whether there are any objects around the winch motor affecting its ventilation and heat dissipation environment. Check if the fan cover, fan blades, and the exterior of the winch motor are dirty and need cleaning. Ensure its heat dissipation effect; whoever discovers the problem should address it promptly.
2. Listen: Listen carefully to see if the operating sound of the winch motor is abnormal and if the surrounding noise is loud. You can use tools like a screwdriver or hearing aid to listen to both ends of the pneumatic winch motor.WinchIf you listen frequently, you can not only locate the winch motor but also determine the amount of oil in the internal bearings and assess any bad vibrations from its drive equipment, allowing for timely measures such as adding bearing oil or replacing new bearings to avoid oil shortages and dry grinding of the winch motor bearings. Cross the circle, sweep the hole, and burn out.
Considering the difficulty of disassembling and replacing large mining bearings, most manufacturers will use open bearings. When lubricating with a grease gun, be careful to use bearing oil (-35℃ to 140℃) and remove the cabin wall screws on the other side. To prevent the engine oil from being pressed into the pneumatic winch motor due to high pressure during lubrication and splashing onto the stator and rotor during operation, which affects the heat dissipation function of the mine winch motor.
3. Touch: Use the back of your hand to detect the temperature around the motor. When the bearings are in good condition, the temperature at both ends is usually lower than that of the middle winding section. If the temperature at both ends of the bearings is high, check the bearings based on the measured bearing sound. If the overall temperature of the winch motor is too high, check the load, equipment, and ventilation conditions of the winch motor in conjunction with the working current, and take appropriate measures.Winch
3.摸:用手背探测Winch电动机周围的温度,当轴承处于良好状态时,两端的温度通常会低于中间绕组段的温度。如果轴承两端的温度较高,请根据测得的轴承声音检查轴承。如果矿用绞车电动机的总体温度过高,则要结合工作电流检查矿用绞车电动机的负载,设备和通风状况,并进行相应处理。
