In the daily use of permanent magnet frequency conversion air compressor, frequency screw air compressor air pressure is insufficient to the normal operation of the air compressor will have a great impact, then cause the air compressor air pressure is insufficient for a variety of reasons, the following small make up and we will talk about it briefly, in general, the permanent magnet frequency conversion screw air compressor to the storage tank filling, the barometer shows that the air pressure does not reach the starting pressure value. When this happens, we need to patiently investigate one by one. 　

1. Whether the intake valve is faulty, the solenoid valve and the permanent magnet frequency conversion air compressor are faulty. 　

2. It is because the air consumption is too large, and the air consumption of the guide permanent magnet frequency conversion air compressor exceeds the exhaust volume.

3. If the screw air compressor does not fill the air tank, then check whether the oil-water separator, air filter and management system will be clogged due to excessive dirt? If clogged, remove the scale.

4. The pressure shown by the barometer does not reach the value of the permanent magnet frequency conversion air compressor of the starting pressure, or the barometer may be malfunctioning. 　　 

5. Whether the air compressor valve plate is leaking, whether the spring is too soft or whether the permanent magnet frequency conversion air compressor is broken, whether the cylinder head has carbon deposits, sand holes, whether the gaskets are damaged, whether the cylinder block and piston ring are excessively worn; according to the searched for faults, in the repair of replacement or damaged parts.

In view of the above permanent magnet frequency conversion air compressor air pressure is not enough, we recommend that users do a good job of regular inspection and maintenance of the screw machine, to avoid small problems into big problems.
