Before the frequency converter technology became popular, air compressor speed regulation mainly relied on the following methods: 1.Pole-changing speed regulation: Speed regulation is achieved by changing the number of pole pairs of the motor. Although this method has a limited speed regulation range, it can achieve greater torque and stable operation. For example, the speed of a four-pole motor i...

The troubleshooting of motors in common compressors involves many aspects. Here are some troubleshooting methods: 1.Winding break inspection: Use a megohmmeter, multimeter or check lamp in series to check the end point and neutral line of the running winding. If the meter is not conducting or the lamp is not bright, it indicates that the winding is broken. 2.Winding short circuit check: Use a mego...

The energy-saving transformation of air compressor is due to the following reasons: 1. High energy consumption: Only 10% of the electric energy consumed by air compressors in industrial production is converted into compressed air, and the remaining 90% is converted into heat energy. This means that the cost of compressed air is much higher than the electricity bill, so energy-saving renovatio...

The air compressor waste heat recovery system is an efficient and energy-saving technology that can make full use of the large amount of waste heat generated during the operation of the air compressor. The following are several key points of the air compressor waste heat recovery system: 1.Energy-saving principle: The air compressor consumes electricity and generates heat during operation, most of...

The daily maintenance of the air compressor cooling system should follow the following steps: 1.Clean the cooler regularly: The air compressor needs to remove dust from the heat dissipation surface every 2,000 hours of operation. You can use a dust gun to blow the cooler until the dust is completely removed. If the dirt is serious, you can remove the cooler and rinse it with water, and finally blo...

When summer comes, the problem of high temperature of air compressor can be solved by the following measures: 1.Keep the air compressor room well ventilated: Make sure the air compressor room has a good ventilation system. You can install exhaust fans in the room to exhaust the hot air and lower the ambient temperature. 2.Clean the cooling system regularly: clean the dust and dirt on the surface o...

Air compressor leakage may cause the following problems: 1.Energy waste: Air leakage will cause the air compressor to require more energy to replenish the leaked air, increasing energy costs. 2.Equipment performance declines: air leakage affects the output pressure and flow of the air compressor, reducing production efficiency. 3.Environmental pollution: Leakage from oil-free air compressors may p...

There are mainly the following methods to deal with water ingress in the lubricating oil of permanent magnet variable frequency air compressor: 1.Use automatic sewage solenoid valve: install an automatic sewage solenoid valve at the drain port at the bottom of the oil-water separator, set the automatic sewage interval to 2 minutes, and the sewage discharge time to 5 seconds. In this way, the opera...
