Permanent Magnet Screw Compressor


Energy saving efficiency

Under full load condition, permanent magnet compressors can supply the maximum air output under the minimum energy consumption, and when the load rate is lower by 20%, can still guarantee the efficiency. permanent magnetcompressors always stays as much as 95% of running efficiency within the scope of the whole gas regulating speed. Save bandwidth control pressure waste of electricity (Variablefrequency energy saving): In order to avoid the frequent starts that result in the cause to the unit, the impact on the grid,stationery compressor must set up a minimum of 1bar pressure range (The minimum and maximum pressure of the air compressor), the control of machine needsto have a pressure gradient when some units are used together, the pressure of the system will be wider VENUS series are of variable frequency control, can start and stop with unlimited times, so no need to set the pressure range, it only needs to set a pressure point, every saving of 0.14 bar pressure range, it will save the energy consumption by 5-7% for the whole system. VENUS series double screw host 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 the nationalstandard

The incomparable reliability

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

Working condition of energy saving

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 remarkable technology

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.

One shaft structure

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%.

Drive charac teristics of VENUS series double screw host with efficient permanent magnet compressor

Permanent magnet compressor adopts high performance bonded ndfeb permanent magnets, without losing magnetism even at 120 deg rees, the service life is more than 15 years. Stater 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 current won't exceed full load current at the running time. It greatly 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.

Saving energy when it starts up(Variable frequencyenergy saving)

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.

High efficiency permanent magnet motor

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.

Benefits of Permanent Magnetic Motor

The benefits of PERMANENTMAGNET field-excited motors over electromagnetically-excited motors include:

Higher efficiency since no electrical energy is used or losses incurred for developing or maintaining the motors magnetic field. Higher torque and power density.Linear torque speed characteristics that are more predictabl Better dynamic performance due to higher magnetic flux density in air gap Simplified construction and essentially maintenance-free More compact size Less bearing current due to large air gap Low temperature due to less rotor losses Ramp up time- shorter, constant power up to maximum speed.
