display cooler noise characteristics and maintenance
1. display cooler uneven placement display cooler placement uneven, causing resonance when the compressor is running. Feature: Promote display cooler noise significantly. Repair method: reposition the display cooler.
2. The water receiving box is not fixed. The water receiving box is fixed on the top of the compressor. If it is not firmly fixed, it will vibrate due to the operation of the compressor and collide with the compressor casing to cause noise. Features: The noise of touching the water box is significantly reduced. Repair method: re-fix the water box.
3. The system is not well evacuated. The refrigeration system is not well evacuated. Because the air is a non-condensable gas, it will increase the flow of refrigerant and cause the display cooler to run loudly. Features: The sound of compression operation is dull, and the sound of snoring and is found when the refrigerant is circulating, and the condensation degree changes unevenly. Repair method: After the refrigeration system is vented, evacuate again and fill with refrigerant.
4. Collision and resonance of exposed refrigeration pipes. If the condenser is not fixed firmly, the contact between the refrigeration pipes, the capillary and the return pipe contact, it will cause resonance or collision when the refrigeration is circulating, and cause noise. The condenser is not firm: the characteristic is that the noise of the condenser is obviously reduced when touching the condenser by hand, just tighten the fixing screws of the condenser. Collision of the refrigeration pipeline: the noise at the hand-touched collision is significantly reduced, just separate the collision pipeline. The capillary tube collides with the air return tube: the noise of the capillary tube is obviously reduced when touching the capillary tube by hand, just insert plastic foam or paper into the capillary.
5. The suspension spring in the compressor falls off, and the display cooler damping spring in the compressor is hung in the upper shell hook. If the suspension spring detached when the compressor is running, vibration and impact on the shell will cause noise. Feature: When the compressor is running, it makes a very loud and metal crash sound. Repair method: remove the compressor, open the shell and hang the hanging spring.
6. Compressor's own reason characteristics: After the refrigeration system is vented, the compressor nozzles are welded and the compressor operates independently. Repair method: replace the compressor of the same model.
