DRY OIL-FREE SCREW AIR COMPRESSOR
01 Dry double stage air end
█ The air compression chamber is separated from the oil chamber. The air side adopts a wear-free sealing system with stainless steel spring-loaded metal ring, and the lubricating oil side adopts a wear-free sealing system with a copper labyrinth seal, and the two do not contact;
█ The secondary rotor is made of stainless steel with strong corrosion resistance;
█ The rotor of the air end and the inner wall of the compression chamber are coated with a strong super coating to prevent corrosion and coating peeling, so that the air end has a longer life;
█ The first-stage casing of the air end is directly cooled by air, and the casing of the second-stage air end is cooled by filtered lubricating oil to avoid the generation of scale and ensure reliable operation.
02 Special motor for air compressor
█ Special motor for air compressor, imported bearing, protection grade IP54, insulation grade F, suitable for harsh environments such as large dust and high temperature;
█ IE3 high-efficiency motor, consumes less electricity and saves costs;
█ The motor is designed with a large margin, and the starting torque is large, which can meet the use of various working conditions.
03 Coupling
█ Torsion elastic coupling, with failure protection function, can effectively damp and reduce vibration and shock generated during operation;
█ The elastic body is only under pressure and can bear a larger load, and the drum-shaped teeth of the elastic body can avoid stress concentration.
04 Intelligent Control
█ Intelligent control system with good man-machine communication interface;
█ Special program, with multiple pressure sensors and temperature sensors, can automatically detect the running state of the machine, without the need for special personnel to take care of it;
█ emergency stop;
█ The Internet of Things can be configured, and the operating status of the unit can be checked on the mobile phone;
05 Quiet centrifugal fan system
█ Using centrifugal fan and cooler, the cooling effect is good;
█ Compared with the axial flow fan, the centrifugal fan has higher wind pressure, lower noise and more energy saving;
█ Due to the high wind pressure, the cooler and filter are not easy to be blocked.
06 Three filters
█ Air filter: large filter area, low intake pressure loss and high energy efficiency;
█ Oil filter: large margin design, high filtering precision and good durability;
█ Oil separator: high filtration precision.
07 Valves
█ Intake valve: Hydraulic normally closed butterfly valve is selected for reliable control;
█ Temperature control valve: The unit is equipped with a temperature control valve to ensure that it is more convenient to start the unit and run more smoothly in a low temperature environment.
Process and Principle
There is a pair of precision-machined male and female rotors in the compressor housing (the male and female rotors do not touch);
The motor drives the male rotor through the transmission device, and then the female rotor synchronous gear is driven by the synchronous gear at the other end of the male rotor, so that the female rotor rotates, so that the air entering the compression chamber is compressed between the tooth slots, and the compressed air is also driven by one end at the same time. to the other end.
The gears and bearings of the compressor are lubricated with special lubricating oil. The oil seal in the main engine prevents the lubricating oil in the bearing cavity from entering the compression cavity, ensuring that the output air is absolutely oil-free, while the air seal prevents the air in the compression cavity from leaking to the outside.
