Why does the air compressor need to discharge water regularly and what are the consequences?

2026-04-10Views:

The air compressor produced by Granklin Group is water-lubricated, and the water content in the compressed gas will be relatively high, so how can the gas be treated without water?

At the rear end of the water-lubricated air compressor, we need to configure a gas storage tank to store the compressed gas. The gas tank can be drained by an automatic drain, and there is a refrigerated dryer at the rear to remove the moisture in the gas.

If the air compressor does not discharge water for two months, what will be the impact?

If the air compressor does not discharge water, it will increase the water content in the compressed air, affect the gas quality, and affect the gas equipment at the back end; the oil and gas separation effect becomes worse, the pressure difference between the oil and gas separator becomes larger, and it will also cause corrosion of the machine parts.

How is water produced?

When the air compressor is working, the internal temperature of the head is very high, and the moisture in the natural air inhaled will form water vapor during the operation of the air compressor. The air storage tank can not only provide a buffer and storage space for compressed air, but also reduce pressure and cool down. When the compressed air through the tank, the high-speed air flow hit the tank wall to produce confluence, in the tank to make the temperature drop rapidly, so that a large number of water vapor to get wild flowers, the formation of condensed water. If you catch up with wet weather or winter, more condensation will form.

When does it usually drain?

Regularly discharge condensate or install automatic drainers according to the specific use environment and working conditions. Mainly depends on the humidity of the inhaled air and the outlet temperature of the air compressor.

The automatic drainer commonly used in air compressors is generally used to automatically drain the condensed water at the bottom of the pipeline, the oil-water separator, the gas tank and various filters. Can be installed in the inconvenience of artificial sewage, such as high, low, narrow place. It can also prevent the artificial drainage from being forgotten and cause the compressed air to be re-polluted by the condensed water.

The main working principle of the automatic drain is that there is an air bottle (equivalent to a balloon) in the automatic drain. In the anhydrous state, under the action of air pressure, the air bottle blocks the water outlet. Water accumulates in the drain. After reaching a certain water level, the buoyancy is greater than the air pressure, the air bottle floats up, the drain is opened, the water is discharged under the action of air pressure, the buoyancy of colleagues decreases, and the air bottle drops to block the drain.
