Inspection of electrical control cabinet

You can use a vacuum cleaner or dry compressed air for cleaning.

Excessive accumulation of dust can affect the heat dissipation of electrical components, leading to overheating and damage to the components.

Check if the wire connections inside the electrical control cabinet are secure, free from looseness, damage, or aging.

Special attention should be paid to checking the wire connections in areas with frequent vibrations.

If any problems are found with the wires, they should be repaired or replaced in a timely manner.

Motor maintenance

Use a thermometer to check the temperature of the motor casing. Under normal circumstances, the temperature of the motor casing should not exceed 40-50 ℃ of the ambient temperature.

Regularly (such as every six months) inspect the insulation resistance of the motor using an insulation resistance meter to ensure good insulation performance.

The general insulation resistance should not be lower than the specified value (such as 0.5 megohms). If the insulation resistance is too low, it may cause motor leakage and require maintenance or replacement of the motor.
