The air compressor is an elevated gas pressure machinery. There are many structural type of air compressor, screw air compressor is of the most popular type of structure. Compared with the traditional piston air compressor, screw air compressor is the most prominent advantage is high reliability, in addition to no vibration, easy to eliminate noise, exhaust pure. 
 Mountains the characteristics of the screw: 
 The running costs of the economy 
 0-100% of the displacement steplessly. When the gas consumption is reduced, the displacement decreases, followed by motor current is also reduced; without gas, air compressor, empty running, empty for a long time automatically shut down. Gas consumption increases, the recovery of heavy vehicles. Energy-saving effect is optimal. 
 Good environmental adaptability 
 Extraordinary cooling system design, especially for the Asian high-temperature, high humidity environment. Excellent vibration isolation and noise reduction measures, so that the installation of the mountains brand screw compressor without a dedicated basis, only to set aside a minimum ventilation and maintenance of space, you can settle your air compressor. Efficient and reliable imported host 
 With SKK fuel injection twin-screw air air compressor head. 
 SKK series screw rotor profile design features: 
 The use of the latest generation of SKK series based on the UK patented screw rotor line, the structure of bilateral asymmetric male rotor, the negative sub-lines curve all the arc and its envelope, the gear ratio to determine the full consider the different power requirements, low-power (≤ 45KW) model is 4:5, high-power (≥ 55KW) is 5:6. The patented rotor compared with the existing other rotor, there are two outstanding advantages: 
 First, the full realization of the curved face of the Surface meshing, thus helping to form a lubricating film of fluid power, reduce the contact zone of the lateral leakage, improve the efficiency of air compressors; and to improve the processing of the rotor, inspection and performance. 
 Two, using the design ideas of the greater trochanter bearing, low-speed ", speed 30 ~ 50% lower than other brands, can reduce noise and vibration, reducing the exhaust temperature and improve the rigid rotor and prolong life, reduce the impurity and the sensitivity of the oil carbide. 
 Third, the power range of 4 ~ 355KW, of which 18.5 ~ 250KW are Direct more 200KW and 250KW 4 pole motor Direct gear box, speed as low as 1480 r / min. 
 Four, fully meet or exceed the national standard GB19153-2003 "volume air compressor energy efficiency limit value. 
 SKK screw extruder design features: 
 , SKK screw extruder host designed using the large rotor, large bearings, the idea of ??low-speed, high-power models are used without gear boxes directly connected at low speed at the same time, reducing the sources of failure, to improve the host force status. 
 Integral chassis, after the bearing and the compression chamber integrated processing, to ensure that the shape and position tolerances of concentricity, parallelism and verticality then to ensure a reasonable gap of the deputy campaign. 
 Third, the rotor axial and radial forces to bear by the different bearings, and the overloading of the world's top SKF bearings.
