What are the common faults of explosion-proof refrigerated dryers? How to maintain?

Explosion proof refrigerated dryer is a specialized equipment used in the fields of chemical, pharmaceutical, food, electronics, etc. Compared with ordinary drying equipment, it has the characteristics of explosion resistance, corrosion resistance, anti-static, etc. However, some malfunctions may still occur during use. The following will provide a detailed explanation of the malfunction symptoms, causes, maintenance, and other aspects.

1、 Fault performance

1. Unstable temperature: During the drying process, the temperature of the explosion-proof refrigerated dryer cannot be maintained stably, and there may be fluctuations in temperature.

2. Poor exhaust: During the drying process, poor exhaust can slow down the drying speed and even prevent the expected effect from being achieved.

3. Oven leakage: The oven is not tightly sealed, causing gas leakage inside and reducing the drying effect.

4. Fan malfunction: During operation, the fan of the explosion-proof refrigerated dryer makes abnormal noises or stops.

5. Electrical malfunction: A malfunction in the electrical system can affect the normal operation of the equipment and may result in serious consequences.

2、 Reason for malfunction

1. Unstable temperature: The internal temperature of the explosion-proof refrigerated dryer is unstable, usually due to unstable air volume, voltage, or damaged temperature sensors.

2. Poor exhaust: During the drying process, foreign objects may get stuck in the exhaust pipe or the exhaust pipe may not be thick enough, resulting in poor exhaust.

3. Oven leakage: During equipment use, the sealing gasket of the oven may be damaged by collision, resulting in gas leakage.

4. Fan malfunction: Equipment malfunction caused by damage to the fan or aging bearings, resulting in poor operation of the equipment.

5. Electrical malfunction: Equipment cannot operate normally due to circuit component failure, poor contact, power supply issues, and other reasons.

3、 Maintenance methods

1. Regular maintenance: Before using the explosion-proof refrigerated dryer, the equipment should be maintained, such as checking the circuit board wiring, solder joints, cleaning dust and oil stains, etc.

2. Pay attention to checking the exhaust pipe: During the use of the equipment, it is necessary to check whether the exhaust pipe is normal and unobstructed, regularly clean the pipe, and prevent the exhaust from being blocked due to foreign objects entering.

3. Pay attention to the sealing of the oven: Regularly check the sealing condition of the explosion-proof refrigerated dryer's oven. If it is found that the oven seal is not tight, the sealing gasket should be replaced in a timely manner.

4. Ensure normal power supply: During the use of the equipment, the stability of the power supply should be ensured, and cable joints should be checked regularly to ensure the normal operation of the electrical system.

5. Regularly replace vulnerable parts: The components of the explosion-proof refrigerated dryer, such as bearings, sealing rings, filters, etc., are vulnerable and should be replaced regularly.

The above are the possible faults and maintenance methods of explosion-proof refrigerated dryers, mainly focusing on equipment maintenance, exhaust pipes, oven sealing, power stability, and replacement of vulnerable parts. Only regular maintenance and inspection can ensure the normal operation of the explosion-proof refrigerated dryer and ensure the safety and efficiency of the equipment.
