1. Configuration of Denair dry-type oil-free air compressor
, host
d= =r d_
Oil-free means that the gas does not come into contact with oil at all during the compression process, that is, there is no oil lubrication between the compression chamber or the rotor of the compressor
In the compressor The bearings, gears and other parts are still lubricated by ordinary lubrication methods, but effective isolation shaft seals are adopted between these lubricated parts and the compression chamber.
Only the air in the compression chamber is dry. The picture above shows a dry oil-free twin-screw compressor.
Denair dry oil-free air compressor host features:
.Sealing
The air compression chamber and oil chamber of the dry oil-free screw are completely sealed once the lubricating oil in the oil chamber enters The compressed air in the compression chamber will contain lubricant, so in order to extend and provide reliable sealing, Denair's oil-free screw compressor uses a wear-free sealing system with a stainless steel spring-loaded metal ring on the air side and a copper labyrinth on the lubricant side. Sealed, wear-free sealing system.

.Rotor
Denair Company has absorbed the problems exposed in the long-term operation of other companies' oil-free screw air compressors and considered the compression after the first stage compression through the cooler. There is water vapor in the air that cannot be separated. In order to prevent water vapor from corroding the surface of the rotor of the second stage of the compressor and causing failure, stainless steel is used to make the second stage rotor.
d= =r d_ .Coating
Usually the inner surfaces of the main engine and casing of oil-free screw air compressors are coated with Teflon or polytetrafluoroethylene material to prevent corrosion and reduce meshing The role of gaps. However, due to the soft material of polytetrafluoroethylene, it cannot withstand the long-term erosion of high-temperature and high-pressure gases and easily peels off, resulting in an increase in the gap between the teeth, resulting in a significant decrease in the air supply volume after 20 years. Therefore, Denair has achieved this result after long-term and unremitting research. A breakthrough is that a strong super coating (r) is coated on the inner wall of the main engine's rotor and compression chamber to prevent corrosion and coating peeling.

. Host heat dissipation
The heat generated during the compression process of the oil-free screw compressor must be dissipated outward through the host casing. The usual method is to cast a However, due to the influence of water quality and high temperature, the inside of the water jacket is easy to scale and the user cannot clean it. Therefore, after the water compartment is scaled, it often cannot operate normally due to the high temperature. Therefore, Denair directly installs the water jacket on the casing of the first-level host. Wind is used for cooling, and filtered lubricating oil is used for cooling in the casing compartment of the second-stage main engine. This avoids the generation of scale, which affects the heat exchange efficiency, and improves the reliability of operation.

.Bearing
Conventional oil-free screw compressors are equipped with a balance piston in order to offset the axial thrust, but the balance piston is easily contaminated by dust and other materials and gets stuck. To eliminate this hidden danger, Denair's dry oil-free compressor uses a pair of independent thrust bearings to replace the balanced piston and use the thrust bearings to bear the radial force.

. Gears and Bearings
In order to ensure the reliable operation of the unit, the transmission gear accuracy has reached the first level and the design life is more than 1 hour. The main engine adopts vacuum demagnetization bearings with a design life of more than 1 hour.
