Start and stop sequence of air compressor and dryer

The start and stop sequence of air compressor and dryer is as follows:

start-up sequence: the air compressor should be turned on first, and then the dryer should be turned on. This is because the dryer needs a stable supply of compressed air to work, and the air compressor is the equipment that provides this supply. In addition, the air compressor will produce a large amount of water vapor, liquid water and oil during the working process. If the dryer is opened first, these moisture and oil will affect the normal operation of the dryer and reduce the dehumidification effect. Therefore, first open the air compressor, wait for it to run stable and then open the dryer, can ensure the normal work of both.

Stop sequence: stop the air compressor first, then stop the dryer. If the dryer is stopped first, the undried air will flow to the back end, which will have a certain impact on the system in places with high compressed air requirements. Therefore, stopping the air compressor first can ensure that the compressed air supply of the system remains stable during the shutdown process, avoiding the impact on the equipment and process due to pressure fluctuations. At the same time, the dryer can continue to run for a period of time after the air compressor is shut down to remove the residual moisture in the system and ensure the drying effect of the system.

It should be noted that for less demanding systems, the start-stop sequence may not be so important, as long as the operation is consistent. However, for systems with higher requirements for compressed air quality, the above start-stop sequence must be strictly observed.
