电冰箱压缩机属小型全封闭制冷压缩机,是家用电冰箱的心脏。它是将气体压缩部分与电机转子、定子部分密封在一壳体内,然后再与冷凝器、蒸发器、过滤器等连接组成电冰箱的制冷系统。它的干燥度与清洁度直接关系到制冷系统能否正常运行。为此国内外有关标准均对压缩机整机的含水量、含杂质量、高低压侧密封试验作出了明确的规定,轻工部部颁标准SG322—83规定:电冰箱用全封闭制冷压缩机整机残余含水量,采用烘箱加热抽气冷却法测量时,不应超过250mg;整机内部杂质含量,采用真空吸滤及干燥后称重法测量时,不应超过100mg。国外如意大利扎努西(Zanussi)公司,对100W
Refrigerator compressors are small, fully enclosed refrigeration compressors that are the heart of household refrigerators. It is a refrigeration system in which the gas compression part is sealed with the motor rotor and stator part in a housing, and then is connected with a condenser, an evaporator, a filter, etc. to constitute a refrigerator. Its dryness and cleanliness are directly related to the normal operation of the refrigeration system. To this end, relevant domestic and foreign standards have clearly stipulated the moisture content, the impurity quality, and the sealing test for high and low pressure sides of the entire compressor. The Ministry of Light Industry issued the standard SG322-83: Fully-enclosed refrigeration compressors for refrigerators. The residual water content of the whole machine shall not exceed 250mg when measured by oven-heated extraction gas cooling method; the internal impurity content of the whole machine shall not exceed 100mg when measured by vacuum suction filtration and after drying. Abroad, such as the Italian company Zanussi, for 100W
