Double screw compressor - Variable Speed series

Low consumption and high efficiency motor which is special designed
It has the following features:
1 large starting torque
2 high configuration SKF spindle ,
making it lower noise and longer life.
3 used insulation class F , protection class IP54.

A specially new generation of low efficiency motors
Independent research and development and production of a new generation of energy-saving motors , the motor by adjusting the relevant dimensions to optimize the parameters of the motor windings , Using of imported efficiently materials, improved the control system, so that the average full loading efficiency is improved by 1.9%. Uninstall current drops more than 10% , the indicators have reached the national levels two energy efficiency standards .

Imported air capacity control system
Full set of imported gas control system
Positive and inverse proportion valve make the pressure signal 100% feedback to the servo cylinder and intake control valve . Displacement intake control valve on the implementation of 0-100 % stepless adjustment, consistent with the gas volume and gas consumption , energy-saving effect is optimal .
Temperature control valve setting cards, closing temperature , automatically adjust the temperature of lubricating oil , the viscosity of the lubricant to maintain the best condition to ensure the exhaust gas temperature above the dew point temperature of the pressure to extend the oil change intervals .
Maintaining minimum pressure valve ensures that the injection pressure necessary for lubricating the body , reducing the air flow rate of the oil separator , the oil separation is best and have the check valve function .

Imported filtration system
Efficient oil separator, oil content is less than the exhaust 3PPM.
Efficient oil filter, filter out the impurities in the lubricating oil,
provide the head rotor and bearings for clean lubricant.
Efficiency air filters, filter out impurities in the air of dust inhalation ,
to protect the head rotor, bearings and others from damage.
Equipped with a pressure sensor, when the filter is blocked, the differential pressure exceeds the set value, the automatic alarm to alert you to maintain or replace.

Imported advanced microcomputer controller Which is powerful at troubles diagnosing and protection

1 LCD display in English
2 Remote / machine next to the selection control
3 Linkage / run independently selected
4 The motor has a start and stop control
5 Air compressor for anti-reverse protection
6 Inspection and control of the temperature protection
7 Detection and protection against voltage
8 RS-485 communication function, support MOOBUS RTU protocol
9 The motor with phase, overload, unbalanced, high voltage, low voltage protection function
10 Highly integrated, high-reliability, high cost
