德耐尔微油螺杆式压缩机-稳定运行时运行频率小于工频DAV

微油螺杆式压缩机-变频系列
OIL INJECTED SCREW AIR COMPRESSOR-VARIABLE SPEED DRIVEN SERIES (5~400KW)

低噪音 Low Noise
稳定运行时运行频率小于工频，机械噪音下降,机械磨损减小;若风机也采用变频驱动,能显著降低空压机,工作时的噪音。During stable operation, the operating frequency is less than the power frequency, themechanical noise is reduced, and the mechanical wear is reduced;lf the fan is also driven byirequency conversion, the noise of the air compressor during operation can be significantlyreduced.

杜绝高压低用
Eliminate the use of high pressure for low pressure requirements
“高压低用"这种现象很浪费,就像“用不完”一样。普通螺杆机始终6-8bar频繁加卸载工作,实际也就只用了6bar,那么多出来的2bar频繁爬升会让机组多消耗14%(每爬升1公斤约多耗7%的电流)。按频繁爬升时间累计是70%，这样一台110KW的普通空压机会因70%的频繁加载多浪费60300元/年。同样如果是变频空压机它始终保持6bar不变的供气,那么也就不存在这2bar的爬升损耗了。
The phenomenon of "high voltage and low use" is wasteful, just like "endless use". Theordinary scre'w machine is always loaded and unloaded frequently at 6-8bar, but actually onlyuses 6bar. The extra 2bar of frequent climbing will cause the unit to consume 1496 morecurrent (about 79 more current per lkg of climbing). The accumulative time of frequentclimbing is 7096, and such a 110KW ordinary air compressor will waste 60300 yuan/year due to70%6 frequent loading, Similarly, if the variable frequency air compressor keeps the same airsupply of 6bar, there will be no climbing loss of 2bar.
