Screw air compressor in the choice to buy, need to examine several aspects of parameters, in order to ensure that the choice is more suitable, today zhongshan fidelity air compressor said under the screw air compressor to pay attention to the following several places.
1. Compressed air quality
According to the requirements of gas equipment for compressor, screw air compressor and supporting equipment should be suitable for purchase.Here are some things to consider:
1) to reduce the oil content in compressed gas, oil removal purifier can be used. If the treatment index is high, multi-stage treatment can be selected.
2) to reduce the water content in compressed gas, water removal equipment can be used.
2. Exhaust pressure
The greater the exhaust pressure of the compressor, the more energy consumption.Will use pressure, pipeline resistance loss and the sum of the pressure drop of supporting equipment, as the choose and buy screw air compressor rated exhaust pressure of the lower limit, in general, should put the pipeline road path choose larger, in order to reduce the resistance loss, to achieve long-term operation to reduce the purpose of energy consumption.The greater the exhaust pressure of the compressor, the more energy consumption.So do not choose high exhaust pressure compressor
3. The displacement
1.1-1.2 coefficients were calculated for the actual amount of air used. As the choice of exhaust capacity, if the choice is too low to reach the specified value of the gas using equipment, if the choice is too large, it will cause large energy consumption and uneconomical operation.At the same time the purchase of large air displacement screw compressor cost is higher.
Combined with the 3 screw air compressor in the purchase need to consider the aspects, and then combined with the actual use of the company itself, generally can choose out of the appropriate
