How to choose the screw air compressor for enterprise procurement

Screw air compressor in the choice of purchase, the need to assess several aspects of the parameters, in order to ensure that the choice of more suitable.

1. Compressed air quality of screw air compressor

according to the requirements of industry gas equipment for compressor gas, screw air compressor and supporting equipment should be selected appropriately. The following points need to be considered:

1) To reduce the oil content in the compressed gas, a degreasing purifier can be used. If the treatment index is high, multi-stage treatment can be selected.

2) To reduce the water content in the compressed gas, water removal equipment can be used.

2. Exhaust pressure

the greater the exhaust pressure of the screw air compressor, the more energy consumption. The sum of the use pressure, pipeline resistance loss and the pressure drop of the supporting equipment is determined as the lower limit of the rated exhaust pressure of the screw air compressor. Under normal circumstances, the diameter of the gas pipeline should be larger. In order to reduce resistance loss and achieve the purpose of reducing energy consumption in long-term operation. The greater the discharge pressure of the compressor, the more energy consumption. So do not use high exhaust pressure screw air compressor.

3. Screw air compressor displacement

calculate the actual total gas consumption ξ 1.1-1.2 coefficient, as the selection of exhaust volume of the model, such as the selection is too low, can not reach the specified value of gas equipment, the selection is too large, resulting in load reduction energy consumption, load reduction operation is not economical. At the same time, the purchase cost of large displacement screw air compressor is higher.

Combined with the three screw air compressor in the purchase of the need to consider, and then combined with the actual use of the company itself, generally can choose the appropriate screw air compressor.
