When the new permanent magnet variable frequency air compressor is started or stopped for many days and restarted, please do not start it directly. Before starting, you should refuel from the air inlet, crank a few laps manually, and jog at least three times before starting (each time approximately 8s, about 30s time interval), this can effectively avoid failures such as burns or jams of the machine head caused by insufficient oil supply when starting up. This operation must be followed especially in the low temperature season.

Inching method:

1. Turn on the emergency stop button, press the "start" button, run for about 6-8 seconds, press the "emergency stop" button to stop, wait for about 30s, and repeat the above steps.

2. When inching, please press the "emergency stop" button to stop, do not press the "stop" button to stop, otherwise because the running time is too long, because the oil supply is not timely, it is easy to burn or burn to death.

3. If the coaxial asynchronous motor and permanent magnet motor cannot be driven manually, it is necessary to jog the machine several times before starting the machine to avoid burns or burns due to lack of oil!

Precautions if not used for a long time:

1. Check whether the machine is flooded;

2. Check whether the machine circuit is normal;

3. Check whether the oil level is within the normal range;

4. Add pollution-free lubricating oil of the same brand from the air inlet;

5. Send the power supply and check whether the three-phase power supply is normal;

6. If there is a dryer, you should start the dryer first.

The above are the issues that the air compressor manufacturers should pay attention to when restarting the permanent magnet variable frequency air compressor after a long shutdown. When the permanent magnet variable frequency air compressor is not used for a long time, the unit is shut down for a long time, and all the lubricating oil in the system is stored in oil and gas barrels. At this time, the lubricating oil has poor fluidity and may cause malfunctions such as high temperature alarms. Therefore, it is recommended that you pay more attention to jog several times when you start the machine for the first time.
