3.48m³/min high efficiency silent screw air compressor 22kw 30hp 0.8 Mpa 220v

Working Principle

The 22kW 8bar variable frequency air screw compressor is a positive displacement rotary compressor with a twin-screw structure design. The core component is a pair of intermeshing spiral yin and yang rotors (the male rotor is convex teeth and the female rotor is concave teeth). The motor drives the male rotor to rotate through a coupling or synchronous gear, and the female rotor realizes reverse synchronous operation through high-precision synchronous gears to ensure that the rotors always maintain a precise meshing gap.

During the suction process, the tooth groove space of the rotor is the largest when it turns to the opening of the intake end wall, and the outside air is sucked into the tooth groove under the action of atmospheric pressure. When the intake side end face of the rotor turns away from the intake port, the air in the tooth groove is closed and the suction process ends.

As the rotor continues to rotate, the air in the tooth groove is brought to the exhaust end, the volume between the tooth grooves gradually decreases, the air is compressed, and the pressure continues to rise. This is the compression process. During the compression process, the oil injection system sprays lubricating oil into the compression chamber. The lubricating oil plays a role in sealing, cooling and lubricating, which helps to improve the efficiency and reliability of the compressor.

When the meshing end face of the rotor turns to communicate with the exhaust port of the casing, the compressed air begins to be discharged until the meshing surface of the tooth tip and the tooth groove moves to the exhaust end face, the tooth groove space is zero, and the exhaust process is completed. At this point, a complete working cycle ends, the rotor continues to rotate, repeats the above process, and continuously provides compressed air for industrial production.

Product Features

1. High efficiency and energy saving

Frequency conversion technology is a core advantage of the 22kw8bar variable frequency air screw compressor. When the traditional fixed frequency compressor is running, the motor always runs at a constant speed, regardless of the actual gas consumption, it maintains the same output power, which will cause a lot of energy waste under low load conditions. The variable frequency compressor is equipped with an advanced variable frequency controller, which can automatically adjust the motor speed according to the actual gas consumption. When the gas consumption decreases, the motor speed decreases, and the compressor output power decreases accordingly; when the gas consumption increases, the motor speed increases to meet production needs in a timely manner. This precise adjustment method effectively avoids the "big horse pulling a small cart" phenomenon. Compared with traditional fixed-frequency compressors, it can save up to 30%-50% of electricity, greatly reducing the company's operating costs.

In addition, the compressor main engine adopts efficient screw tooth profile and optimized rotor design to ensure that while efficiently compressing air, internal leakage and friction loss are minimized, further improving the energy utilization of the whole machine.

2. Stable and reliable

The screw rotor, the core component of the compressor, is made of high-quality alloy steel and undergoes precision machining and strict dynamic balancing tests to ensure stability and reliability at high speeds. Advanced manufacturing technology and high-precision processing equipment ensure the rotor's tooth profile accuracy and meshing clearance, effectively reducing wear and vibration and extending the service life of the compressor.

At the same time, the machine is equipped with a complete lubrication system and cooling system. The lubrication system uses high-quality lubricating oil and fine filtering devices to provide good lubrication and protection for key components such as rotors and bearings, reducing the risk of wear; the cooling system uses efficient coolers and reasonable air duct design to ensure that the compressor always maintains a suitable temperature during operation to avoid performance degradation and failures caused by overheating.

3. Low-noise operation

In industrial production environments, noise pollution not only affects the work efficiency and physical and mental health of employees, but may also cause environmental problems. The 22kw8bar variable frequency air screw compressor is designed with full consideration of noise control. By optimizing the structure and operating parameters of the rotor, the mechanical vibration and air flow pulsation during the operation of the compressor are reduced. At the same time, noise reduction measures such as soundproof covers and sound-absorbing materials are adopted to effectively reduce noise transmission. Compared with traditional air compressors, its operating noise can be reduced to 60-75dB (A), creating a quieter and more comfortable working environment for enterprises. The advantages of energy saving and consumption reduction are significant.

In the context of global advocacy of energy conservation and emission reduction, enterprises have become an inevitable choice for sustainable development by reducing energy consumption and improving energy utilization efficiency. The outstanding performance of 22kw8bar variable frequency air screw compressor in energy saving and consumption reduction makes it a powerful tool for enterprises to achieve green production.

Through variable frequency speed regulation technology, the compressor can adjust the motor speed and output power in real time according to the actual gas consumption, avoiding the energy waste of traditional fixed frequency compressors under low load conditions.

In addition, the synergy of the compressor's efficient host design, optimized lubrication and cooling system, and intelligent control system further improves the energy utilization rate of the whole machine, reduces energy consumption and operating costs. In the long run, the use of variable frequency air screw compressors can not only save a lot of electricity expenses for enterprises, but also reduce the carbon emissions of enterprises, and enhance the social image and market competitiveness of enterprises.

The 22kw8bar variable frequency air screw compressor plays an important role in many industrial fields with its outstanding features such as high efficiency and energy saving, stable and reliable, intelligent control and low noise. With the continuous advancement and innovation of technology, it is believed that this compressor will bring efficient, energy-saving and environmentally friendly compressed air solutions to more enterprises, helping enterprises achieve the goal of sustainable development. When choosing a compressor, companies should consider their actual needs and working conditions, comprehensively consider factors such as equipment performance, quality, and energy-saving effects, and choose the product that best suits them.
