Pression d'échappement

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.

Entretien et maintenance

1. Contrôler quotidiennement le niveau d'huile, la température et la pression des gaz d'échappement et vérifier l'absence de bruits anormaux ;
2. Avant de démarrer chaque semaine, ouvrez la vanne de vidange du séparateur pour évacuer l'eau de condensation, vérifiez qu'il n'y a pas de fuites partout, inspectez la vanne de sécurité et vérifiez l'usure de la courroie (visuellement) ;
3. Vérifier régulièrement la soupape de contrôle d'admission, la soupape de pression minimale, les bornes des fils de connexion du boîtier de commande électrique, la soupape de sécurité et le ventilateur de refroidissement ;
4. Nettoyez et balayez régulièrement le refroidisseur et vérifiez la fiabilité de la soupape de sécurité ;
5. Remplacer régulièrement l'élément du filtre à huile, l'élément du filtre séparateur d'huile, l'élément du filtre d'admission et l'huile de lubrification.
