2.The energy consumption is 10%~15% lower than normal.

3.Air compressor design with several types of technology patent, real bigger air flow.

4.State-of-the-art screw element, original air end, ladvanced SAP profile design, superior Sweden SKF element bearings.

Centrifugal little air compressor, also known as turbo compressor, is mainly used to compress gas. It is mainly composed of a rotor and a stator. The rotor includes an impeller and a shaft. The impeller has blades, a balance disc and a part of the shaft seal; the main body of the stator is a cylinder , There are also devices such as diffuser, curve, reflux, vent pipe, exhaust pipe and so on.

The function of the main shaft is to support the rotating parts (impeller, balance plate, etc.) mounted on it and transmit torque. When determining the size of the designed shaft, not only the strength of the shaft must be considered, but also the critical speed of the shaft must be carefully calculated. The so-called critical speed is the speed when the shaft speed is equal to the natural frequency of the shaft.

In a multi-stage centrifugal little air compressor, because the gas force on both sides of the impeller of each stage is inconsistent, the rotor will receive a resultant force directed to the low pressure end, which we call the axial force. The axial force is not conducive to the normal operation of the compressor. It makes the rotor move to one end, and even makes the rotor and the shell collide, causing an accident. Therefore, efforts should be made to balance it. The balance plate is a part that balances the axial force by using the pressure difference between the gas on both sides of it. In the main shaft of the thermal sleeve, the balance disk usually balances only a part of the axial force, and the remaining axial force is borne by the thrust bearing.

The main function of the diffuser is to slow down the flow of high kinetic energy from the impeller, and effectively convert the kinetic energy of the gas into pressure energy. Diffusers are generally divided into vaneless diffusers, vane diffusers and straight wall diffusers.

Its main function is to collect the gas behind the diffuser or behind the impeller and lead them out of the little air compressor to flow to the conveying pipe or gas cooler. In addition, in the process of gathering gas, in most cases, due to the outer diameter of the volute The gradual increase and the gradual increase of the circulation area also played a role in reducing speed and expanding pressure.

Advantage

1. The centrifugal compressor has large air volume, simple and compact structure, light weight, small unit size and small floor space.

2. Balanced operation, reliable operation, high operation rate, few friction parts, because of the small amount of spare parts required, maintenance costs and personnel.

3. In the chemical process, the centrifugal compressor can achieve an absolutely oil-free compression process for the chemical medium.

4. The centrifugal compressor is a rotary motion machine, which is suitable for direct drive of industrial steam turbines or gas turbines. For general large-scale chemical plants, by-product steam is often used to drive industrial steam turbines, which provides the possibility for comprehensive utilization of thermal energy.
