How to choose screw air compressor

How to buy suitable and durable air compressor equipment in the air compressor market, provides you with professional knowledge of purchasing screw air compressors Exhaust pressure of screw air compressor

The higher the discharge pressure of the screw air compressor, the more energy it consumes. The sum of the operating pressure, pipeline resistance loss and the pressure drop of the supporting equipment is set as the lower limit of the rated exhaust pressure of the screw air compressor. Generally, the diameter of the gas pipeline should be selected larger. In order to reduce the resistance loss, to achieve the purpose of long-term operation and reduce energy consumption. The higher the discharge pressure of the compressor, the more energy it consumes. Therefore, do not use a compressor with an excessively high discharge pressure.

Optional screw air compressor displacement

Calculate the actual total gas consumption ╳ 1.1-1.2 coefficient. As the model of the selected exhaust capacity, if the selected model is too low, it will not reach the specified value of the gas equipment, and if the selected value is too large, the energy consumption of load shedding will be large. Uneconomical operation of the load. At the same time, the purchase cost of purchasing a large displacement screw air compressor is higher.

Choose the compressed air quality of screw air compressor

According to the requirements of the industry's gas equipment for compressor gas, screw air compressors and supporting equipment should be purchased appropriately. The following points need to be considered:

1) To reduce the oil content in the compressed gas, an 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 the compressed gas, a complete set of water removal equipment can be used.
