PM VSD Screw Air Compressor

Product Description

1.Intelligent Control System Direct display of discharge temperature and pressure, operating frequency,current,power,operating state.Real time monitoring of discharge temperature and pressure, current, frequency fluctuations. 2.The Latest Generation High Efficiency Permanent Motor Insulation grade F, protective grade IP55, suitable for the bad working conditions.No gearbox design, motor and main rotor through the coupling directly connected, high transmission efficiency.Wide range of speed regulation, high precision, wide range of air flow regulation.The efficiency of the permanent magnet motor is higher 3%-5% than regular motor, efficiency is constant, when the speed drops, still remain the high efficiency. 3.The Latest Generation Super Stable Inverter Constant pressure air supply, air supply pressure is accurately controlled within 0.01Mpa.Constant temperature air supply, general constant temperature set at 85C, make the best oil lubrication effect and avoid high temperature to stop.No empty load,reduce energy consumption by 45%, eliminate excess pressure.For each 0.1mpa increase of air compressor pressure, energy consumption increases by 7%.Vector air supply ,accurate calculation, to ensure that the air compressor production and customer system air demand at all times to maintain the same. 4.Wide Working Frequency Range To Save Energy Frequency conversion ranges from 5% to 100%.When the user s gas fluctuation is large, the more obvious energy saving effect and the lower the low-frequency running noise, applicable to any place. 5.Small Start-up Impact Use frequency conversion permanent magnet motor, start smooth and soft.When the motor starts, the current does not exceed the rated current, which does not affect the power grid and the mechanical wear of the main engine, greatly reduces the power failure and prolongs the service life of the main screw machine. 6.Low Noise The inverter is a soft start device, the start-up impact very small, noise will be very low when start-up.At the same time, PM VSD compressor running frequency is less than the fixed speed compressor during stable operation, mechanical noise decreases very much.
