PERMANENT MAGNET SCREW COMPRESSOR

The connecting parts of permanent magnet compressors are much less than that of other equivalent compressors, is directly driven by permanent magnet compressors, when air compressor is running, it doesnt need to consider the gear, pulley, belt, even the shaft or shaft seal wearing of moving parts

Permanent magnet compressor can keep high efficiency even in low speed, ensuring its obvious advantage in energy saving when the gas is little. The variable frequency ranges from 5% to 100%, and the ordinary variable frequency can only be from 50% to 100%. The common variable frequency air compressor saves energy only when unloading the system (Variable frequency energy saving): There will be an unloading time for the stationary air compressor during its air consumption fluctuates, even when running idly it will still need to consume 45% of its electricity, but VENUS series of variable frequency control can ha ve no unloading, there is no waste existing. If the more sets of the systems used, the more of energy saving it will be.

The permanent magnet struct ure of permanent magnet compressors revolutionary unique uses less electricity to provide more compressed air and bigger air volume adjustment range.Comparing with ordinary air compressor, it can save energy by 15%-38%,comparing with common variable frequency compressor, it can save energy by 5%- 10%.The bigger of the system gas fluctuation, the more obvious of the energy savingeffect appears.

Stationary air compressor startup current is about 3to 6 times of the rated working current, if frequently star ted, it will waste a lot of energy, VENUS series start with no current shock, and startup as soft start, the maximum current shall not exceed its rated working current, there will be no waste of energy. At the sametime,it also greatly reduces the impact on power grid equipment, and won't cause harm to electrical equipment.

Permanent magnet motor adopts the embedded integrated with compressor shaft directly connected structure, thestructure is morecompact, no need to use belt, gear coupling and so on of transmission components, completely without transmission loss,and the transmission efficiency is of appr oximate 100%.

VENUS series double screw host is the combination of science and ideal, accurate and exquisite combination, make the perfect efficient core host, the host on the research and development,developed jointly by college and enterprise, dominated byscientific leading scientists doc toral tutor, national professional laboratory testing, key parts are finite element strength analysis. In order to ensure the quality of each part can be maximum.optimization, provide strong technical support for the product stability,high efficiency and long running. Comprehnsive optimization of the tooth surface precision of the rotor and rotor meshing sex, optimize the end surface precision of the screw and the rotor position precision, optimization of the exhaust pressure,displacement and the best combination of vent, with advanced manufacturing equipment and superb manufacturing process,create high efficiency, high reliability, high precision screw host.VENUS series doubles crew compressor with its continuous optimization of rotor type line and internal structure, provides industry leading level specific power.The host energy efficiency is above the first level of energy efficiency of national standard.

Equipped with high efficiency permanent magnet compressor (PMcompressor),compared with ordinary high-frequencycompressor,energy-saving per formance is more outstanding. Especially in low speed, it can still keep high efficiency of compressor.At rated speedor different speed conditions, the efficiency of permanent magnet compressor is higher than that of the ordinary variable frequency motor, energy saving effect is more remarkable.

Permanent magnet compressor adopts high per formance bonded ndfeb permanent magnets, without losing magnetism even at 120 deg rees, the service life is more than 15 years. Stator coil adopts inverter dedicated corona resistant enabled wire. Insulation performance is outstanding, and the service life is much longer. It can achieve soft start, the motor currentwon't exceed full load current at the running time. Itgreatly reduces the impact to power grid equipment at the same time, and it will not cause damage to electrical equipment No motor bearing:rotor with permanent magnet is installed directly on the outer part of the male rotor shaft, such structure doesn't need to use bearing, therefore it can eliminate the fault point from the motor bearing.
