Direct Driven Screw Air Compressor DA-30GA/W

Click to enlarge
Direct Driven Screw Air Compressor 22 KW:

Configuration characteristics
1. A precisely-made central bracket is used to keep the motor aligned permanently with the air end.
2. A highly resilient coupling is adopted to make the compressor operate smoothly, and the elastomeric is long in useful life.
3. The discharge pipe is double-wall corrugated pipe, and the oil way uses a special high-pressure hose which is resistant to temperature up to 125℃.
4. For the extremely high temperature conditions in some districts, the large-area plate heat exchanger and high- efficiency water chiller are used.
High quality shaft coupling elastic body can buffer and compensate for the imbalanced moment of operation. The elastomeric is designed into an in volute cambered surface, which effectively avoids stress concentration and improve the buffering effect of the elastomeric to increase its bearing capacity. In addition, the high quality materials ensure excellent durability for the elastomeric and can better absorb the vibration arising from the rotation to remove noise.

Reliability
Since no wearing parts are used for the double-screw air end, it can operate for up to 40, 000-80, 000 hours between failures if well maintained.
