Analysis and treatment of leakage in refrigerator

To make a successful refrigerated display cabinet, it is necessary to make full and reasonable use of the unique space; Complete the practical function of displaying goods, beautiful and novel appearance, attract attention, and give people a good impression; Comply with merchant CI requirements. For a variety of display purposes of the refrigerator, the overall structure of the refrigerator is all detachable and removable parts, without using any glue materials, a screwdriver can complete the disassembly of the entire refrigerator, convenient disassembly, transportation, etc.

Why can't the refrigerator start immediately after it stops

Reason: In the action of refrigerator bai, the suction side of du's refrigeration series compressor is called dao low pressure side, and its pressure zhuan is slightly higher than shu atmospheric pressure. The exhaust side of the compressor is called the high pressure side, and the pressure is up to 117.7 pa (12 kg/cm2). The pressure difference between the two sides is very large, and the two sides of the system still maintains this pressure difference after shutdown. If you start immediately, the compressor piston pressure, motor starting torque can not overcome such a high pressure difference, so that the motor can not start, in the state of gridlock, the motor winding current will increase sharply, the temperature increases, 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, and the oil level should not be higher than half at this time; The return pipe is blocked; The device of the return pipe (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 separator inside the cylinder is damaged; The unit has oil leakage; Coolant disintegration or extended use.
