18bar Portable Air Compressor Diesel Engine 385cfm Mining Use With Jack Hammer

Kaishan brand diesel engine screw air compressor is used to power pneumatic tool and machines such as pneumatic breaker, jack hammer, drilling machine, oil cleaning machine, sandblasting machine, drilling rig and so on.

Kaishan LGCY Two-stage Compressed Diesel Movable Screw Air Compressor

At present, Kaishan screw air compressor product energy efficiency level has been in the world's leading level. In addition to advanced profile technology, we also have global invention patents to ensure lower fuel consumption. If you compare our products with similar foreign products, you will soon find that the fuel savings of our products are very obvious. The advancement of technology is self-evident, and the reliability has already been proved by hundreds of units in service.

Design Characteristics of Screw Rotor Profile:

1. It fully realizes "Convex-Convex" engagement to assist in the formation of hydrodynamic lubrication film, to reduce horizontal leakage passing the contact zone, and to improve efficiency of the compressor; improve rotor processing and testing property.

2. It adopts the design thought of "large rotor, large bearing and low speed method", thus its revolving speed is 30-50% lower than that of other brands to reduce noise, vibration, and exhaust temperature, improve rotor rigidity, increase service life, and reduce sensibility to sundries and oil carbide.

3. Its power range is 4~355KW, where 18.5~250KW applies to the compressor without direct-coupled gearbox, 200KW and 250KW apply to the compressor with Level 4 direct-coupled motor and the speed is as low as 1480 rmp.

4. It fully conforms to and exceeds requirements in GB19153-2003 Limited Values of Energy Efficiency and Evaluating Values of Energy Conservation of Capacity Air Compressors.

We also have drilling rig, jack hammer, drill rod and other related products.
