Oil-free screw compressor

I. definition of oil-free screw air compressor
The rotor of the oil-free screw compressor is not directly contacted, there is a certain gap between them. The rotor rotates through the synchronous gear, while the synchronous gear ensures the rotor clearance while transmitting power. The so-called "oil free" means that the gas does not contact with the oil in the compression process. However, the bearings and synchronous gears of the compressor still need to be lubricated by lubricating oil. Only the effective shaft seals are used to isolate the lubricating parts and the compression chambers.

Two. Part of the oil-free screw air compressor.
The oil-free screw air compressor can be clearly divided into three parts: electronic control and driving parts, compression parts and cooling parts.

Three, the characteristics of oil-free screw air compressor
The biggest advantage of oil-free screw compressor is to provide pure and oil-free compressed air. The oil-free screw air compressor also has the advantages of simple structure, high speed, small volume, small vibration, stable gas supply, high gas supply quality, small flow pulsation, less wearing parts, low noise and high automation. It also has the characteristics of installation, operation, operation and maintenance.

Four. Classification of oil-free screw air compressors
The oil-free screw air compressor can be divided into air-cooled oil free screw air compressor, water-cooled oil free screw air compressor, power frequency oil free screw air compressor, and frequency conversion oil-free screw compressor.

Five. Application area of oil-free screw air compressor.
The oil-free screw compressor has no lubricating oil in the compression chamber, so it can provide pure and oil-free compressed air for textile, metallurgy, food, chemical industry, medicine, petroleum and air separation.

 Variable frequency oil-free rotary compressor FRV-220 in rock field
The FRV-220 features of the variable frequency oil-free rotary compressor in rock field 1, the constant control of the pressure of the oil-free air compressor in the field, so that the target pressure is controlled within the range of + 0.01MPa. Compared with the standard model (load and unloading), it achieves 8.5% energy saving. 2. Compared with the standard model (load and unloading), the oil free rotary air compressor in the rock field is still 19% energy saving when the load is 50%.
