Commercial refrigerator freezer leakage fault and maintenance knowledge
Commercial refrigerator freezer has become an indispensable necessity for merchants. When the refrigerator fails, how to check and deal with it? Common leakage faults and maintenance knowledge of commercial refrigerators.
1. The Commercial Restaurant Refrigerators has micro-leakage or induction electricity with hemp inductance. Severe leakage is not safe for humans. Due to humidity, high humidity, and reduced insulation resistance of electrical components and shelves, etc., it causes slight leakage;
2. Insulation damage of compressors, electrical appliances, circuits, etc., so that parts that should not be charged are charged, and short-circuited with the cabinet, causing serious leakage. Such a situation is caused by leakage of the insulation layer due to aging or scratching of the insulation layer. If such leakage occurs, it should be repaired in time.
3. The screw connecting the ground wire of the freezer is loose, the wire is short-circuited due to rust, or the ground wire is not inserted during maintenance, so that the ground wire loses its function and there is a feeling of numbness. The correct grounding method for the grounding wire of the freezer is to use a 50cm long steel pipe to insert it into the ground, and use a grounding wire to introduce it into the room and connect it to the socket. This will ensure that the freezer and the ground are fully in contact, and the leakage phenomenon is also Will be greatly improved.
4. The internal coil and the housing should be insulated. If the performance of the internal insulating material is degraded, there will be resistance between the coil and the housing, so that the housing is charged and the cooling cabinet is charged through the cooling pipeline. Disposal: When performing fault repair, use polyester film to wrap the broken line to prevent direct friction with the casing. If the insulation of the enameled wire of the compressor appears to fall off, then it should be repainted.
