The selection of air compressor is very important to the air compressor equipment and users themselves, which is too wasteful and expensive; Too small selection may cause the air compressor to be in the loading state for a long time, insufficient air consumption or pressure failure. Therefore, the selection of air compressor requires correct and appropriate methods. The expensive one is not necessarily the best, but the suitable one is the best.
1. The first thing to consider is the use of compressed air. As we all know, compressed air is widely used in production in all walks of life. Different industries have different uses for compressed air.
2. Minimum operating pressure and the amount of compressed air required per minute. According to statistics, for every 1kg pressure rise, 7% more power is consumed.
3. Gas demand. If the gas output of the air compressor is too small, and the gas output is less than the gas consumption, the air compressor will always be in the loading state, which will cause huge energy consumption.
4. Different types and grades of dryers and precision filters are selected and configured according to different gas quality. Poor quality will affect the quality of gas equipment and final products.
5. Considering the size of the air compressor station, ventilation and heat dissipation conditions, noise isolation, waste heat, waste water recovery, etc. will cause the use of energy.
6. As for cooling methods, there are mainly two kinds: air cooling and water cooling. Air cooling is a commonly used cooling method, which does not require additional investment in cooling towers, but must have good ventilation conditions, and is generally applied to small and medium-sized enterprise users; The water-cooled model needs to build a water tower, and its operating temperature is not affected by the environment, which is conducive to the service life of the air compressor. However, it has the shortcomings of ice breaking and blocking, and is generally used for larger machines.
7. Power supply planning, voltage demand and voltage drop stability must be required. Centrifuges are usually high voltage, completely immovable, and have impact on the power grid during startup, so they should be kept in regular operation.
