Natural gas driven screw compressor

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. The screw main engine has a long service life

The American 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 American Sullair screw main engine 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 threads. If oil enters the shaft seal, the reverse threads will pump the oil back into the compressor;

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

6.High exhaust pressure

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

7.Advanced purification design

At present, the natural gas compressor on the market needs to be equipped with additional natural gas pretreatment equipment before use to ensure that the gas source enters the compressor without impurities, while the user of Guanruida natural gas screw compressor does not need to configure a purification device, and can directly connect to the wellhead for compression work .

8.Environmentally friendly design

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

9.No need for electricity in remote areas

Dragon Force natural gas compressor can use natural gas source to generate power drive, without the need for users to configure additional power supply facilities, reducing user costs.

10.Satellite remote control

The natural gas-driven screw compressor can be equipped with PLC to realize remote satellite remote control. At the same time, it uses the solar energy and wind energy on site to transmit signals to the remote base station, which can realize completely unattended and remote control operation under extremely harsh conditions.
