The refrigeration dryer will be used with an air compressor in many environments. If it is used or installed improperly, various failures are prone to occur, especially in some enterprises with a large amount of air. Once the refrigeration dryer fails to operate normally, it will cause air failure. The press strikes. In fact, many situations are caused by improper use. It is not a malfunction of the dryer. Just a few days ago, a customer reported to repair the air compressor failure. After the maintenance personnel arranged by our company came to the door, it was found that the drain pipe of the dryer was blocked. , The equipment can operate normally after dredging, so we must pay more attention when using the refrigeration dryer. Today, Dehaha will explain it to you.
1. Don't put it in the place where the relative humidity is higher than 85%. Do not place it in a dusty, corrosive or flammable gas environment. Do not place it in a place where there is vibration or condensation water may freeze. Do not get too close to the wall to avoid poor ventilation. It is necessary to use it in an environment with corrosive gas, and you should choose a dryer with rust-proof copper tubes or a stainless steel heat exchanger type dryer. It should be used at ambient temperature below 40°C.
2. Do not connect the compressed air inlet wrongly. In order to facilitate maintenance, a bypass pipeline should be provided to ensure a maintenance space. It is necessary to prevent the vibration of the air compressor from being transmitted to the dryer. Do not add the weight of the piping directly to the dryer.
3. Do not stand the drain pipe upwards, do not fold or squash it.
4. The allowable fluctuation of power supply voltage is less than ±10%. A leakage circuit breaker of appropriate capacity should be provided. Must be grounded before use.
5. The temperature of the compressed air inlet is too high, the ambient temperature is too high (above 40℃), the use flow exceeds the rated processing air volume, the voltage fluctuation exceeds ±10%, and the ventilation is too poor (please change the air in winter, otherwise the room temperature will also rise ) Etc., the protection circuit will work, the indicator light will be off, and the operation will stop.
6. When the air pressure is higher than 0.15MPa, the drain port of the normally open automatic drain can be closed. The displacement of the air compressor is too small, the drain is open, and air is blown out.
7. The quality of compressed air is poor. If dust and oil are mixed, these stolen goods will stick to the heat exchanger, reducing its work efficiency, and the drainage is also prone to failure. It is hoped to install a filter at the inlet of the dryer, and to confirm that the drainage is not less than once a day.
8. The vent of the dryer should be cleaned with a vacuum cleaner once a month.
9. Turn on the power supply, and then turn on the compressed air after the running state is stable. After stopping the operation, you must wait for more than 3 minutes before restarting.
10. If you use an automatic drain, you should always check whether its drainage function is normal. Always clean the dust on the condenser. Check the pressure of the refrigerant frequently to determine whether the refrigerant is leaking and whether the capacity of the refrigerator has changed. To check whether the temperature of the condensed water is normal.
