Main features of mining screw air compressor:
1. High efficiency, energy saving, stability
In recent years, the international host rotor adopts new asymmetric type line. Such as Germany’s GHH type line, Sweden’s x type line, Japan’s α, β type line and domestic XP type line, high efficiency and energy saving.
Energy Saving Motor
Mining screw air compressor has the characteristics of forced air transmission, that is, the exhaust volume does not change with the change of exhaust pressure, the exhaust pressure increases or decreases every 1MPa, the exhaust volume correspondingly reduces or increases by about 1%, at the same time, mining screw air compressor internal pressure ratio has nothing to do with the rotational speed, any rotational speed type of the internal pressure ratio is almost a fixed value.
Mining screw air compressor in a wide range of exhaust volume, exhaust pressure and speed range, the efficiency change is not big, and can maintain a high value, the specific power change is very small. Due to the high rotational speed of the air compressor, without reducer, it has the performance of continuous air transmission, and the pulsation of air transmission is very small accordingly, if there is no special requirement, it can not be installed with another air storage tank.
2. Excellent environmental protection design
Soundproof box design, compact and complete unit, small volume, light weight, low noise, small area, no special foundation design, construction, easy installation. For example: kotech KDP-5/7 series type air compressor volume flow rate of 5.2m3/min, working pressure of 7bar, motor power of 36.8kW, noise of 78 plus or minus 3dB (A), the maximum exhaust temperature of 100 ℃, weight of 1200kg, dimensions of 3230×1440×1425 box unit including air compressor, motor, instrumentation, electronic control, After cooling system, etc., without the need to purchase another instrumentation cabinet, electronic control cabinet.
