Screw Driven Air Compressor

The screw-driven air compressor GA series is equipped with a high-efficiency permanent magnet motor, which has excellent energy-saving performance, smooth operation and low noise, allowing it to be installed close to the point of air consumption.

The permanent magnet synchronous variable frequency air compressor is a new type of air compressor with excellent quality, high efficiency and energy saving. Currently, only a few advanced countries and regions in the world have this technology. It is a high-end trend in the future development of the air compressor field. Its design The concepts and technical means have broken through the traditional technical concepts and integrated the current advanced technical elements.

The permanent magnet synchronous variable frequency air compressor always operates under load and has no unloading operation, so there is no waste of power. The efficiency of the permanent magnet synchronous motor is very high. Compared with the efficiency of ordinary motors, it is at least 2% higher. It uses less energy to produce greater torque. The energy saving effect is significant, and the energy consumption is maintained at an economical level.

The permanent magnet synchronous variable frequency air compressor is equipped with a high-efficiency permanent magnet synchronous motor (PM motor). Compared with ordinary motors, it is smaller and more energy-saving. When installed with a dedicated inverter, it will achieve energy saving that ordinary induction motors cannot match. Effectively, it uses high-performance rubidium iron boron permanent magnets that do not lose magnetism at a temperature of 120°C and have a service life of up to 15 years. Its stator coil uses corona enameled wire specially designed for frequency converters, with excellent insulation performance. Due to the strong magnetic permeability of the rotor , the magnetic flux rate is extremely high, so the diameter is very small, and it can be directly installed on the extended shaft of the male rotor, eliminating the need to use a shaft.
 

Efficient, reliable and durable, the new GA series compressors are based on the above design principles and can provide customers with high-quality compressed air no matter how harsh the operating environment is. At the same time, due to its rich knowledge and experience and pioneering innovative spirit, the series of compressors continue to reduce costs for customers throughout the entire production process and ensure safe, stable and continuous operation.

The rotary compressor is a new type of compressor. Its motor does not need to convert the rotary motion of the rotor into the reciprocating motion of the piston. Instead, it directly drives the rotating piston to rotate to complete the compression of the refrigerant vapor.

This kind of air compressor is more suitable for small air conditioners, especially for household air conditioners. For example, the rotary air compressors produced by American General Electric Company and Wopu Company are designed with better overheating prevention and lubrication devices. It uses a cooling method that leads part of the refrigerant liquid from the condenser to the compression chamber through piping and sprays it in the cylinder, which improves the cooling effect.

A screw air compressor is a type of air compression equipment commonly used in industrial and commercial applications. Their main purpose is to compress a large amount of air into a smaller volume and provide high pressure and high flow rate of compressed air.

 

The purpose of using a screw air compressor is as follows

 

1. Providing power: Screw air compressors are the power source for many industrial equipment and tools, such as pneumatic tools, spray painting equipment, refrigeration equipment, etc. They compress air to high pressure and then pipe it to equipment that requires compressed air for power.

 

2. Store energy: An air compressor can store compressed air in an air tank for emergency use. This method of storing energy can cope with peak gas consumption and sudden gas consumption, providing a stable and continuous supply of compressed air.

 

3. Processing and production: Screw air compressors play a key role in many production processes. They are used in gas separation, pipeline transportation, material transportation and other processes to provide stable compressed gas and play a vital role in many industrial fields.

 

Screw air compressors can also be integrated with other equipment and systems, such as cooling systems, air conditioning systems, pumping stations, etc., to achieve wider applications and benefits.

 

To sum up, different applicable scenarios also determine the market positioning, advantages and disadvantages of the two types of compressors.
