Wiring is as follows:
1. The three live wires of the air switch are respectively connected to the three input ends of the AC contactor of the air compressor, and the three output ends are respectively connected to the motor.
2. Any live wire is connected to the coil of a 380V AC contactor, the other end of the coil is connected to the normally closed contact of the thermal relay, the other end of the normally closed contact is connected to the normally closed contact of the air pressure switch, and the other end of the normally closed contact is connected to another live wire (if the coil of the AC contactor is powered by 220V, this wire is not connected to the live wire, but directly to the neutral wire)

Many enterprises in the purchase of permanent magnet variable frequency air compressor, often because of the permanent magnet variable frequency air compressor industry is not familiar with, do not know what kind of permanent magnet variable frequency air compressor brand. Generally speaking, in the domestic permanent magnet variable frequency air compressor market, there are several commonly used
If it is moisture-proof maintenance, you can refer to the following methods: 1. Check whether there is water around the air compressor. Find out the foundation, geological structure, flood control facilities and emergency rescue facilities around the air compressor room in detail, and find out the hidden dangers and weak links.
The specific application of screw air compressor in food and pharmaceutical fields, the application of air compressor in various industries is very extensive, but the requirements of different industries for screw air compressor are also different. The application and light of screw air compressor in food and pharmaceutical fields are introduced in detail below.
The water lubricated air compressor produced by Shanghai granklin group includes power frequency air compressor, variable frequency air compressor and permanent magnet air compressor. the air compressor is made of stainless steel, and the compressed gas is 100% free of oil.
View detailsHigh-end air compressors are basically monopolized by foreign brands, mainly: the price of the whole machine of major international brands is relatively expensive. Domestic products such as: granklin is not bad, the price of the whole machine is relatively cheap
There are so many domestic air compressor manufacturers, and the number is large. Before purchasing, it is best to look at the factory scale, production capacity, and various certifications and user cases of the product, and evaluate whether the air compressor manufacturer can meet its own needs.
