Pmvf37-ii permanent magnet frequency conversion two-stage compression sales: buy cheap air compressor really "cheap"?Do not believe us to calculate!
Screw air compressor energy saving, load to see the specific power, unloading to see the internal pressure.Than power is an important indicator of whether air compressor energy saving, many bosses in purchasing air compressor machine, only stared at present purchase cost, cheap I buy whose young, little imagine, this is a big mistake, buy cheap air compressor, maybe a electricity eating tigers, after watching meter to run quickly, and then to love dearly unceasingly.
What is specific power?The specific power is the input power of the air compressor set (note: if the motor power of an air compressor is 37KW, it refers to the output power and the actual operation is larger than 37KW) divided by the actual gas production, and the value obtained is the input specific power of the air compressor, and the unit is KW/M3/min.
According to gb19153-2009 standard, query motor power, exhaust pressure, cooling mode, etc., can see each air compressor is a level of energy efficiency, or two or three energy efficiency.
For example, the screw air compressor with 37KW, gas production of 6 M3/min and working pressure of 8 kg is the dividing line between primary energy efficiency and secondary energy efficiency.8.1KW/M3/min is the dividing line between secondary energy efficiency and tertiary energy efficiency, 7.3-8.1 belongs to secondary energy efficiency, 8.9KW/ M3/min is the market access value of whether the air compressor can be produced and put into the market, 8.2-8.9 is the tertiary energy efficiency, greater than 8.9 is a super power product, the country does not allow production.(note: air compressor input specific power can be China energy efficiency logo website to query, the formal air compressor manufacturers can be found.)
Now let's do a comparison, a 6 cubic air compressor, one of the manufacturer mark than power is 7.1 KW/M3 / min (level) of energy efficiency, and the other air compressor vendors would mark is 8.6 KW/M3 / min (3) of energy efficiency, the level of energy efficiency of air compressor air compressor per hour than level 3 energy efficiency power-saving = (8.6 7.1) * 6 = 9 degrees, according to the industrial electric 1 yuan money once, work 10 hours a day, 300 days a year, so can save a year 9 * 10 * 300 = 27000 yuan.
The investment of the air compressor used in the factory is composed of three parts, one is the initial purchase cost, the other is the daily operation cost, namely the electricity fee, and the third is the maintenance cost. Usually, the initial purchase cost only accounts for a small part of the total investment.So the user to buy air compressor machine, know more about the than the power of the air compressor, good air compressor purchase price is more expensive than some cheap brand air compressor, save electricity, however, can take back to a year, a less air compressor said have to use a decade, eight years, the account or for the user to be yourself.
