Permanent magnet variable frequency air compressor is a new generation of energy-saving products that will be applied and promoted in the context of encouraging energy saving and emission reduction. Permanent magnet variable frequency air compressor is the choice of our customers, with large displacement and equipped with permanent magnet motor, which has more outstanding energy-saving performance compared with ordinary FM motor. Especially at low speed, it can still maintain high motor efficiency. The motor is small in size, generally about 1/3 of an ordinary FM motor, and easy to disassemble and install.

With the rapid development of China's economy, more and more attention is paid to the technology of low consumption, and this technology has attracted attention. The possibility of applying the frequency conversion speed control technology in the field of air compressor supply, which can save power and improve the performance and quality of air compressor supply at the same time, has become a topic of our concern.

How to carry out basic maintenance of permanent magnet variable frequency air compressor? In order to ensure the normal and reliable operation of permanent magnet variable frequency air compressor and the service life of the unit, it is necessary to make a detailed maintenance plan, implement dedicated operation, regular maintenance, regular inspection and maintenance, and keep the air compressor set clean and free of oil and dirt.

1. When repairing and replacing each part according to the above table, you need to make sure that the pressure in the permanent magnet inverter air compressor system has been released, isolated from other pressure sources, the switch on the main circuit has been closed, and the safety sign of not allowed to close the gate has been made.

2. The replacement time of compressor cooling lubricant depends on the use environment, humidity, dust and the presence of acid and alkali gas in the air. Newly purchased air compressor needs to be replaced with new oil after 500 hours of operation, and then every 4000 hours according to the normal oil change interval. If the annual running time is less than 4000 hours, the oil should be replaced once a year.

3. The oil filter needs to be replaced after 300-500 hours of start-up operation of permanent magnet inverter air compressor, after the second use of 2000 hours, and then every 2000 hours according to the normal time.

4. When repairing and replacing the air filter or air inlet valve, remember not to let any debris fall into the main chamber of the compressor, and close the main engine inlet when operating. After the operation, turn the main engine several times in the rotating direction by hand to make sure there is no obstacle before turning on the machine.

5. When the permanent magnet inverter air compressor is running, check the belt tightness about once every 2000 hours. If the belt is slack, you need to adjust the belt until it is tightened; in order to protect the belt, you need to prevent the belt from being scrapped due to oil contamination throughout the process.

6. Every time you change the oil, you need to change the oil filter at the same time.

How to clean the cooler of permanent magnet inverter air compressor? Let's take a brief look at the following.

For every 2000 hours of operation, in order to remove the dust on the cooling surface, open the cooler blowing hole cover on the fan bracket and use the dust blowing air gun to blow the cooler until the dust on the cooling surface is completely cleaned. If the cooling surface of Shangruo is heavily soiled and hard to clean, remove the cooler, pour out the oil in the cooler and seal the four inlets and outlets to prevent dust from entering, then blow off the dust on both sides of the permanent magnet inverter air compressor with compressed air or rinse it with water, then blow dry the water stains on the surface and put it back to its original position.
