What is the problem of the lack of phase of the main engine of the screw air compressor? —Shared by Sollant

The lack of phase of the main engine of the screw air compressor refers to the loss of power supply of one phase of the three-phase wires in the main power supply, resulting in the failure of the main engine to operate normally. This condition is usually caused by one of the following reasons:

Power failure:

This can be caused by an interruption in the power supply, a faulty power line, a blown fuse, or a tripped circuit breaker. If the power supply of one of the phases is disturbed, interrupted or damaged, the main engine of the screw air compressor will not be able to operate normally.

Motor failure:

The motor of the screw air compressor base unit may suffer a failure, causing one of the phases to not work properly. This can be caused by things like broken coils inside the motor, damaged insulation, or faulty motor components.

The lack of phase of the screw air compressor host may cause the following effects:

Reduced output capacity:

The lack of phase will reduce the output capacity of the screw air compressor host, unable to provide normal compressed air flow and pressure.

Unbalanced operation:

The lack of phase may cause the host motor to run unbalanced, causing vibration and noise, and may even cause additional load and damage to mechanical parts.

System fault protection:

Screw air compressors are usually equipped with protection devices, such as current protection devices and phase sequence protection devices. When the host detects a phase loss, these protection devices may trigger, stopping the host to prevent further damage.

If you suspect that there is a lack of phase in the main unit of the screw air compressor, you should take the following measures immediately:

Shutdown:

Immediately stop the operation of the screw air compressor. This is to prevent further damage caused by phase loss and to ensure the safety of the operator.

Check the power supply:

Check the power supply is normal, make sure all phase wires are connected and powered properly. Check electrical equipment such as power switches, circuit breakers, and fuses for proper operation.

Check the motor wiring:

Check the wiring of the main motor of the screw air compressor. Make sure that the three-phase wiring of the motor is connected correctly. Check the motor coils and insulation for damage.

Use test equipment:

Use suitable electrical test equipment (such as a multimeter or a phase loss detector) to test the power supply and the phase wire of the motor. This will help confirm if there is a phase loss problem.

Seek professional help:

If you’re unsure how to fix a problem or need to make electrical repairs, it’s best to contact an experienced electrical engineer or repairer. They can perform detailed electrical inspections and repair work to ensure problems are properly addressed.

Please note that before performing any electrical work, always disconnect the power source and follow proper safety procedures and practices. Electrical work involves high voltages and potential hazards, so care must be taken to ensure personal safety and equipment integrity.
