Analysis and treatment of electric leakage in the refrigerated cabinet

Analysis and processing of the leakage of refrigerated cabinets. A successful refrigerated display cabinet needs to make full and reasonable use of the unique space; complete the practical functions of the displayed products, beautiful and novel appearance, attract attention, and give people a good impression; it is suitable for merchants CI requirements. For the various display purposes of the refrigerator, the whole structure of the refrigerator also uses all detachable and assembleable parts, without any glue material, a screwdriver can complete the disassembly and assembly of the entire refrigerator, which is convenient for disassembly, assembly and transportation. Wait. 　　 But mostly because the refrigerator has been used for a long time, the parts are aging or damaged, and the condensation in the refrigerator

Why can't the refrigerator start immediately after stopping

Reason: In the operation of the refrigerator bai, the suction side of its refrigeration series compressor is called the low pressure side of the dao, and its pressure is slightly higher than the atmospheric pressure of shu. The discharge side of the compressor is called the high pressure side, and the pressure is as high as about 117.7 Pa (12 kg/cm²). The pressure difference between the two sides is very large, and the system on both sides still maintains this pressure difference after shutdown. If it is started immediately, the compressor piston pressure and motor starting torque cannot overcome such a high pressure difference, so that the motor cannot be started and is in a locked-rotor state. The motor winding current will increase sharply and the temperature will increase. If the time is too long, it is likely to burn the motor. .

Refrigeration compressor maintenance knowledge

The correct position should be observed when the unit is loaded. At this time, the oil level should not be higher than half; the oil return pipe is blocked; the device of the oil return pipe (the distance from the bottom of the oil separation core) does not meet the requirements; the exhaust pressure is too low when the unit is running; The oil separation core is broken; the internal partition of the separation cylinder is damaged; the unit has oil leakage; the coolant is degenerated or used for an extended period of time. 1 Trouble phenomenon: The exhaust temperature of the unit is high (over 100°C) The coolant level of the unit is too low (should be seen from the oil sight glass but not more than half) The oil cooler is dirty; the oil filter core is blocked; the temperature control valve Failure (bad component) The oil cut-off solenoid valve is not energized or the coil is damaged; the oil cut-off solenoid valve diaphragm is broken
