Key points for troubleshooting and maintenance of permanent magnet submersible motors?

Permanent magnet submersible motor is an important equipment widely used in fields such as petroleum, chemical, metallurgy, and water conservancy. Regular troubleshooting and maintenance are essential to ensure its normal operation and extend its service life. This article will focus on the key points of troubleshooting and maintenance for permanent magnet submersible motors.

1、 Troubleshooting

Inspect the appearance of the motor and insulation components. Check the appearance of the permanent magnet submersible motor to see if there is any obvious deformation or damage. At the same time, insulation components such as insulation pads, insulation boards, insulation sleeves, etc. should also be inspected to ensure that they are intact and undamaged.

Check the bearings and seals. Secondly, check the bearings of the motor to see if there are any abnormal sounds, overheating, or other phenomena. At the same time, it is necessary to check the sealing components, such as sealing rings, gaskets, etc., to ensure good sealing effect.

Checking the cooling system of the permanent magnet submersible motor is an important component to ensure its normal operation. Therefore, during the maintenance process, it is necessary to carefully inspect the cooling water pipes, cooling pumps, coolers, etc. to ensure the normal operation of the cooling system.

Checking the motor winding and the winding of the contact permanent magnet submersible motor is a crucial part of its current conduction. Therefore, during the maintenance process, it is necessary to check whether there are any abnormal situations such as broken strands or wires in the winding. At the same time, it is necessary to check the contact condition of the contacts to ensure good contact.

Check the connection between the motor control box and cables. Check for aging, broken strands, and other conditions in the cable. At the same time, check the operation of electrical components such as fuses and circuit breakers inside the motor control box.

2、 Maintaining Key Points

Regular replacement of lubricating oil is required for the bearing operation part of the permanent magnet submersible motor, which requires protection with lubricating oil. Therefore, it is necessary to regularly replace the lubricating oil and ensure that the injected lubricating oil meets the standard requirements.

Proper anti-corrosion work is necessary as permanent magnet submersible motors often operate in damp and corrosive environments. Regular cleaning and painting are necessary to protect the motor casing and internal components.

Maintaining the cooling system of the cooling system is crucial for the normal operation of permanent magnet submersible motors. Therefore, it is necessary to regularly clean the impurities in the cooling water pipeline and check the operation of the cooling pump and cooler.

Regular inspection of motor windings is the core part of permanent magnet submersible motors, and it is necessary to conduct regular inspections. Check for aging, broken strands, and other phenomena in the winding, and repair and replace them in a timely manner.

Pay attention to the motor load. When using a permanent magnet submersible motor, it is important to control the motor load. Excessive load can cause the motor to overheat, affecting its normal operation. Therefore, it is necessary to adjust the load reasonably during use to ensure the normal operation of the motor.
