Selection and installation precautions for permanent magnet submersible motors?

Permanent magnet submersible motor is a special type of motor widely used in equipment such as submersible pumps, submersible compressors, and submersible winches. It has significant advantages in underwater operations due to its stable performance, long lifespan, and high power density. The following will introduce the selection and installation precautions of permanent magnet submersible motors.

1、 Selection of Permanent Magnet Submarine Motors

Power selection: Select the appropriate power size based on the working requirements and power supply conditions of the diving equipment. Generally speaking, excessive power can waste energy, while insufficient power may not meet work requirements.

Speed selection: Choose the appropriate speed according to the working needs of the diving equipment. Excessive rotational speed can cause equipment vibration and noise, while low rotational speed may cause the equipment to malfunction.

Insulation level selection: Select the appropriate insulation level based on the working environment of the diving equipment, ensuring that the motor can operate normally in humid environments and underwater operations.

Sealing level selection: Select the appropriate sealing level based on the working depth and water pressure requirements of the diving equipment. The higher the sealing level, the better the reliability and durability of the motor underwater.

2、 Installation precautions for permanent magnet submersible motors

Installation location selection: Choose a location closer to the workplace for installation, which is convenient for equipment maintenance and repair. The installation location should avoid exposure to humid environments, and should also avoid being subjected to gravity loads and external impacts.

Smooth installation: During the installation process, ensure a smooth installation between the motor and the diving equipment to avoid the impact of vibration and impact on the motor.

Sealing requirements: During installation, it is necessary to ensure good sealing between the motor and diving equipment to prevent corrosion and damage to the motor caused by water and moisture.

Cable selection: Choose waterproof cables suitable for use in underwater environments, and ensure that the cable connections are firm and reliable to prevent water leakage and short circuits.

Grounding protection: Ensure proper grounding protection for the motor to prevent leakage accidents during diving.

Operation monitoring: After installation, it is necessary to conduct operation monitoring to ensure the performance and stability of the motor in working condition. If any abnormalities are found, they need to be dealt with in a timely manner.
