Process gas screw compressor

Messages
  • Main features of Guanruida process gas screw compressor series

    1. Direct drive, no gears, higher reliability

    1). Avoid the possibility of failure caused by gear wear and increase reliability;

    2). Reduce vibration and noise;

    3). Higher transmission efficiency;

    4). Reduce the power consumption generated by the gear part;

    5). Reduce the lubricating oil consumed on the gears, and at the same time increase the life of the lubricating oil.

    2. The bearing is arranged in a special way and the force is better

    1). Roller bearings are used to bear radial loads;

    2). Tapered roller bearings bear axial and radial forces;

    3). No start-up pre-lubrication requirements.

    3. Balance piston (reduce bearing stress)

    The balance piston is installed on the two rotors. Under the action of pressure, oil enters the piston to produce a force that partially offsets the thrust load. This will reduce the thrust acting on the thrust bearing, and the bearing life will be longer.

    4. Long service life of screw main engine

    U.S. Sullair process gas special screw main engine has been deeply cultivated in the field of special compressors for decades. After continuous improvement and innovation, the performance is far better than similar screw main engines of other brands. Practice has proved that the Sullair screw main engine has superior performance and good reliability, and the service life of the main engine is more than 80,000 hours.

    5. The screw host adopts a mechanical seal with zero leakage

    The Sullair screw main engine of the United States is optimized for high-pressure working conditions. The John Crane mechanical seal with reliable performance and two-stage seal structure is selected to ensure that the shaft seal of the screw main engine has zero leakage and no oil and natural gas overflow the compressor.

    1) The first stage is a labyrinth seal structure with reverse thread. If oil enters the shaft seal, this reverse thread will pump the oil back into the compressor;

    2) The second level is a high temperature resistant and hardened graphite sealing structure, and it has a good sealing effect with tungsten surface and fluorine rubber elastomer.

    6. High exhaust pressure 

    Guanruida's natural gas screw compressor has a maximum discharge pressure of 507psig (3.5Mpag), which is currently the world's highest technology for screw compressors.

    7. Environmentally friendly design

    Guanruida natural gas screw compressor originated from the United States, and pays special attention to environmental protection. It automatically recovers impurities and special treatment, and the body is in harmony with nature.
