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". The ordinary screw machine is always loaded and unloaded frequently at 6-8bar, but actually only uses 6bar. The extra 2bar of frequent climbing will cause the unit to consume 1496 more current (about 7%6 more current per lkg of climbing). The accumulative time of frequent climbing is 7096, and such a 110KW ordinary air compressor will waste 60300 yuan/year due to 7096 frequent loading. Similarly, if the variable frequency air compressor keeps the same air supply of 6bar, there will be no climbing loss of 2bar.
