Product Characteristic:
1. The products with features of compact structure, beautiful appearance, convenient for installation, easy of operation, lower discharge temperature, large discharge capacity, perfect dynamic balance. The compressor package has lower vibration, with higher reliability and performance cost ratio. Applied for filling dry and clean nitrogen(with pressure of 50MPa) to stationary or mobile high pressure storage equipment.
2. The compressor was driven by motor, diesel engine or natural gas engine, with suction pressure 0.7-0.8MPa, rated discharge pressure 50MPa, gas capacity 1200-2400Nm3/h.
3. Mixed cooling, no need for connecting cooling water. The compressor is safe in operation, with small vibration and noise during running,
4. Adopt cylinders that are a combination of mature double-acting structure and differential type, which will decrease piston force.
5. Type W and Type M, integral skid-mounted, five-stage compression, the compressor system can be integrated. Compact structure, beautiful appearance, each stage small compressor ratio, lower discharge temperature, long service life, easy operation, convenience of installation and maintenance, the cost is 1/3 of imported compressor and can replace imported compressor.
The compressor is mainly applied to research & development institutions, chemical industry, machinery, petroleum industry etc. This type of compressors are used for nitrogen injection and gas supply in CNPC high-pressure oil well.
