What are the forms of oil free air compressor?

At present, the oil-free machine is widely used. What are the forms of oil-free air compressor?

First: water lubrication screw

water lubricated oil-free air compressor is the use of pure water, therefore, its equipment in the operation process with sealing, cooling and lubrication effect. In addition, due to the different designs of various manufacturers, the main engine rotor has double rotor and single rotor, and some materials are made of stainless steel, copper alloy and ceramic rotor, so its power rotating bearing system is completely oil-free. Because the injection of water can reduce the temperature and the speed is low, the volumetric efficiency of the water-lubricated oil-free air compressor is relatively high, and the product is energy-saving. The domestic Granklin Group uses a single screw rotor made of stainless steel. The oil-free air compressor will elevate technology to a new height.

Second: dry screw

the dry type oil-free screw air compressor generates compressed air through high-speed rotation of double rotors. Since the air in its compression chamber does not contact any oil mist, the gas discharged is oil-free, and its screw rotor expands at high speed during operation to generate gas compression. The screw of the dry type oil-free air compressor will be sprayed with resin objects to protect the screw from damage in high-speed friction. After 4 years of high-speed operation, a new rotor should be considered.

Third: Reciprocating

today, the oil-free micro reciprocating air compressor is a motor-driven symmetrical crankshaft connecting rod mechanical structure, and the reciprocating oil-free air compressor has a single-cylinder or multi-cylinder structural arrangement. Because the reciprocating compressor will generate vibration and a lot of compression heat, Frequent replacement of vulnerable parts such as pistons, rings, and cylinders is required, which is noisy, has a shorter life and lower cost.

Oil-free compressed air is also widely used in various industries, but an oil-free compressed air acquisition method is also recommended here, and the oil pollution in the gas is removed by oil removal. Using catalytic oxidation degreasing equipment, it can be directly connected to the back end of oil-containing or oil-free machine to obtain stable 0-level oil-free compressed air.
