排気圧力

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

Exhaust volume

Calculate the coefficient of actual total gas consumption* 1.1-1.2 as the model for selecting exhaust volume. If the selected value is too low and cannot meet the specified value of gas equipment, and too high is selected, it will result in high energy consumption and uneconomical operation during load reduction. The cost of purchasing a large displacement screw air compressor is relatively high.

Compressed air quality

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

1. To reduce the oil content in 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 compressed gas, water removal equipment can be used as a matching solution.

メンテナンスと維持管理

1. オイルレベル、排気温度、排気圧力を毎日点検し、異常音がしないか点検する；
2. 毎週始動する前に、セパレーターのドレンバルブを開けて凝縮水を排出し、各所に漏れがないか点検し、安全弁を点検し、ベルトの摩耗を点検する（目視）；
3. 吸気制御バルブ、最低圧力バルブ、電気制御ボックスの接続線端子、安全バルブ、冷却ファンを定期的に点検する；
4. クーラーは定期的に清掃し、安全弁の信頼性をテストする；
5. オイル・フィルタ・エレメント、オイル・セパレータ・フィルタ・エレメント、吸気フィルタ・エレメント、潤滑油は定期的に交換してください。
