Design features of screw rotary:
I. Fully engaging "curved interfaces", it enables fluid film lubrication to form, lowering cross leakage of the contact belts, while improving the efficiency of the air compressor. Meanwhile, it also improves the operating and testing performance of rotors.
II. The design features "big rotors and bearings at a low speed". The rotational speed is lower than products of other brands, which may reduce noise levels and vibration, lower the temperature of displacement, and improve the rigidity of the rotors. As a result, the service life is extended, and the sensitivity to impurity as well as oil and carbide substances is reduced.
III. The power range falls between 4 kW and 355 kW. Amongst which, 18.5 kW to 250 kW is for direct drive without the gearbox; 200 kW and 250 kW are for direct drive of four-stage engines with a rotational speed as low as 1,480 RPM.
