Product description:
The latest generation of screw rotor profile by British patent technology, the structure of the male rotor, bilateral asymmetric female rotor, its type line curve for all circle-arc and its envelope. In order to optimize the ratio of power, gear ratio is 5:6.
The rotor to the other existing rotor compared, there are two prominent advantages: one is to fully realize the "surface" tooth, so as to contribute to the formation of the hydrodynamic lubrication film, reduce the transverse leakage through the contact zone, improve the efficiency of the compressor; processing, performance test and improvement of rotor. Two is the use of "design of large rotor, bearing, low speed", speed was 30-50% lower than that of other brands, can reduce noise and vibration, increased rigidity of rotor, prolong the service life, reduce the sensitivity of impurities and carbide.
Efficient screw rotor design featuresA, screw host design uses a large rotor, bearing, the low speed of the train of thought, main models of high power are used without gear box directly connected, in the low speed at the same time, reduce the fault source, improve the stress condition of the host.Two, using the integral frame, a rear bearing integrated processing base and the compression chamber, to ensure that the same bearing, parallelism and perpendicularity tolerance and etc. ensure reasonable clearance between moving parts.Three, the bearing and seal the world advanced.Four, host intake, exhaust open close time, nozzle, the oil return port, location, according to the latest research results of design, internal pressure ratio is reasonable, full of oil and gas heat exchange.Five, not only low noise, and the noise frequency is lower than other brands of 30-50%, reduce the human ear stimulation.Axial force of six, rotor and the force from the different bearing, and the axial force balancing device, ensure that the host a moving parts in a reasonable interval operation.Seven, the bearing by the circulating oil flow flushing, cooling, lubrication, and effectively improve the bearing working conditions, reduce the operating temperature.Eight, the host is simple and reasonable in structure, reliable, low failure rate, easy assembly and maintenance.Nine, by the National Laboratory, the main performance indexes such as the ratio of power, noise, reliability has been ranked in the world top level.
