Automatic drainage device for air compressor

The automatic drainage device of the air compressor is an important part of the air compressor system. Its main function is to automatically discharge the condensed water in the pipeline, the gas storage tank, the oil-water separator and the filter. The following is a detailed description of the air compressor automatic drainage device:

1. working principle

the working principle of the automatic drainage device of the air compressor is mainly based on buoyancy. When a certain amount of condensed water is accumulated inside the device, the floating ball or air bottle will float up under the action of buoyancy, thereby opening the drain port and discharging the condensed water. After draining the condensed water, the float ball or air bottle will descend and block the drain to prevent gas leakage.

Main structure of 2.

Drain hole: located under the valve body, it is the channel for condensate to drain.

Sealing gasket: used to prevent air leakage and ensure the stability of the drain valve. It is made of highly elastic material, can withstand high pressure and wear resistance.

Piston: Control the on-off of the drain hole through up and down movement to realize automatic drainage. The piston is made of high-quality materials, which have high strength and corrosion resistance after special treatment.

Spring: to ensure the normal movement of the piston, and control the state of the drain hole. The spring is made of high-quality steel, with long life, high toughness and reliability.

3. common types

electronic drain valve: The drainage is controlled by the electromagnetic valve, and the switch can be set to adjust the opening time and cycle of automatic drainage. This type is currently more widely used.

Physical drainer: Use the buoy in the drainer to open and close the valve under the action of buoyancy. When the cooling water level rises, the buoy also rises, which automatically opens the valve to drain water.

4. Troubleshooting

when the air compressor automatic drainage device fails, the possible causes and solutions include:

drainage valve blockage: need to clean the dust, oil and other debris in the valve.

Sensor failure: The failed sensor should be checked and replaced.

Pipeline blockage: need to clean the blockage in the drain line.

Float ball drain valve problem: If the float is blocked and cannot be lowered or the valve port is stuck and not closed, the air source should be disconnected, and the drain valve should be removed for cleaning and inspection.

In general, the air compressor automatic drainage device plays a vital role in the air compressor system. In order to ensure its normal operation, it should be inspected and maintained regularly.
