Direct Driven Air Screw Compressor 7.5Kw/10Hp TUV,CE,ISO certificates in cheaper price!
Advantages of LGCD Direct Driven Screw Compressor:
1. Coupling driving system
2. Highly competitive price
3. Economic running costs
4. ISO, CE,TUV, SGS certificates
LGCD Direct-driven Air Screw Compressor features:
First, the curved face of the rotors engaged fully, thus contributing to the formation of a hydrodynamic lubrication film, reducing the contact zone of the lateral leakage, improve compressor efficiency; as well as to improve the processing, test performance of the rotor.
Second, using the design ideas of bigger rotor, bigger bearing, low-speed ", speed lower than other brands up to 30 ~ 50%, this could reduce noise and vibration, reducing the compressed air temperature and improve the rigidity of rotor and prolong its life, reduce sensitivity to the impurity and the oil carbide.
Third, fully meet or exceed the national standard GB19153-2003 "air compressors energy efficiency limit !
1 Drives and electrics
The almost loss-free power transmission guarantees reliable, high-performance compressor operation. The regular maintenance requirement is reduced to lubrication of the motor. All the electronic components are brand products of leading
manufacturers. rives and electrics.
2 Air end block – reliable centrepiece – Design in Germany
The centrepiece of Direct-driven Screw compressor is the air end, which is constructed and manufactured with the most modern production methods in China. The optimal air end for your compressor can be used on a modulating basis. In frequency-controlled units, where the operating pressure changes, adjustments can also be made on the frequency controller to optimally adjust the speed of the compressor to the compressor performance.
3 Electric motor
Only electric motors from well-known manufacturers of protection class IP54/IP23 are used in our Direct-driven Screw compressor. As a standard, the drive motors are monitored both thermally (via the thermistor of the motor) as well as electronically(overload protection via the frequency inverter).
