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)

Screw air compressor pumping slow how to deal with, screw air compressor pumping slow power generally have the following reasons: screw air compressor pumping slow how to deal with? 1, the host problem. Check the air supply power of the equipment host, and close the valve behind the air tank
Shanghai granklin group has many cases in the food industry. food factories that need oil-free screw air compressor can contact us for inquiry. In recent years, the food industry has developed rapidly, and the automation level of food factory equipment has also been continuously improved. Machine, electricity, gas and other integrated technology is increasingly applied to the food industry, oil-free screw air compressor
View detailsAt present, many screw air compressors in the traditional sense of society are single-stage compression screw air compressors, and their energy consumption and electricity consumption greatly consume a lot of electric energy and functional conversion rate, which is constantly guiding the continuous innovation and progress of the air compressor industry, making me
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.
View detailsThe variable frequency non-oil-water lubricated air compressor sold by Shanghai Granklin Group has a large gas production, stable operation and low temperature. It is a very ideal gas source for medical treatment, food and various special gases.
View detailsIt is recommended that you consider these comprehensive factors when buying air compressors: price, use, gas production, and after-sales service. Imported brands are more expensive than domestic air compressors, but the cost performance of domestic brands and
Screw air compressor adopts pre-set configuration screw air compressor, only single power connection and compressed air connection, built-in cooling system, greatly simplifying the installation work. Screw air compressor has high efficiency, dimension-free
The comparison between oil-free air compressor and oil-free air compressor can be expanded from the following dimensions: 1. Working principle Oil-based models During the compression process, the lubricating oil participates in the air compression and plays the role of heat dissipation and lubrication. The compressed oil-gas mixture is treated by the separator, and the oil content is passed through.
The main features of the water lubricated screw air compressor are: reasonable structure, ideal force balance; no radial and axial force during operation, only rotational force. Single-stage compression ratio is high, the shape of the structure size is small: high speed light load, easy to establish hydrodynamic lubrication.
When purchasing water lubricated air compressors, the factory often asks about 75kW air compressors. After the sales manager Shen of Shanghai granklin group air compressor company learned about it, it turned out that this enterprise was used to produce food. because food safety was very important, our sales manager chose the new water for our customers.
