Influence of frequency conversion transformation of air compressor on air compressor accessories

The frequency conversion transformation of air compressor is one of the ways of energy-saving transformation of air compressor. It is not only as simple as saving electricity, but also can prolong the service life of the machine and protect the accessories of air compressor.

Effects on the main motor

1. The use of Class F insulation and above will not affect the insulation life of the motor at all;

2. The minimum speed is not lower than the setting requirements, and the cooling of the main motor is not affected;

3. The average speed is reduced, which can increase the service life of the main motor bearing.

Effects on the nose

1. The service life of the machine head bearing is inversely proportional to the speed;

2. The speed is reduced and there is no dead time, so the lubrication of the machine head is more sufficient;

3. Eliminate the impact of star-delta starting on the machine head and main motor bearings, prolonging the service life;

4. Extend the service life of the belt or elastic coupling by more than 3 times.

Influence on the service life of cooling oil

1. The transformation itself does not change any oil circuit system;

2. Reduce the average load rate and reduce the cooling system load;

3. Effectively reduce the exhaust temperature, and the probability of high exhaust temperature is greatly reduced;

4. Reduce the rotation speed, reduce the cycle times of cooling oil and prolong the service life.

Influence on the service life of other accessories

1. Eliminate the impact of the loading and unloading state on the intake valve, minimum pressure valve, pipeline and cooler, etc., and prolong the service life;

2. It will not have any effect on air filter, oil filter, oil separator core, etc.

Impact on the grid

1. The energy-saving control system is equipped with an isolated power supply control system, a complete filter circuit and a special reactor for protecting the power grid and frequency converter, so the interference to the power grid can be eliminated or minimized;

2. It has no effect on the grid voltage, and the minimum starting current is 25% of the standard model;

Influence on the self-protection function of the unit

Except the protection of the main motor is protected by the control system, the others are controlled and protected by the compressor itself.
