11. sound The continuous buzz we heard is this kind of sound 2 When compressor is produced there must be clearance between components When refrigerator is running the existing of clearance will make some components touch and gives out sound Especially at starting and stopping the forces acted on compressor components changes greatly and bigger sound will be generated 3 Noise of flowing liquid The running process of compressor is a continuous gas in and out process If the pressure of refrigerant gas breathed in or exhausted out changes suddenly vibration sound will be generated 4 PDF created with pdfFactory trial version www pdffactory com Heeecee Refrigerator Model HBC 70 200 india MAINTENANCE SERVICE AND TROUBLE SHOOTING 4 Resonance sound of compressor components Compressor parts such as compressor body exhaust tube noise eliminator in compressor supporting spring etc will cause resonance sometimes and give out sound 5 Collision between body and shell Compressor body is suspended by three pieces of spring or supported by spring in the shell At starting or stopping forces acted on compressor changes greatly and sometimes make the body contact its shell and makes sound This situation is of shore duration 6 The electromagnetic sound a hermetically sealed motor is relatively small 12 6 3 How is the sound of water flowing generated Answer When liquid refrigerant is flowing espec
12. the same linear expansion coefficient the for requirement between terminals and the shell is more than 0 5 million ohm The reason of terminal leakage is that soda glass is broken or there are conductive materials such as water dirt etc adhered to terminals 1 6 PDF created with pdfFactory trial version www pdffactory com Meeeee Refrigerator Model HBC 70 200 India MAINTENANCE SERVICE AND TROUBLE SHOOTIN If electricity leakage occurs outside the compressor please use tetra chloromethane or alcohol to clean it If the leakage occurs in the inner of compressor it needs to be changed 3 Leakage of temperature controller because of too long a period of service or too high temperature or too much dirt or too high humidity there may be electricity leakage If it has been defined that there is leakage of temperature controller please change 4 Leakage of starting relay during mounting and repairing screw of relay lead is easy to contact the shell and leakage will then occur If you suspect the relay is bad check it If there is leakage please make the connections again and leave a piece of insulation paper under the screw 5 Leakage of fan because of too high humidity of refrigerator environment or a bad fan controlling unit the fan is burned after long time operation and thus causes leakage Using voltammeter to measure the insulation resistance between each respective connection terminal and the refrigerator
