常州新北龙虎塘镇美浮孚压缩机油-EP锂基脂销售
高速氨冷冻机油50℃粘度数25-35m/s,要求具有高抗磨性和低凝点(-38℃至-40℃。溶在油中的制冷剂会降低油的粘度,因此,油与制冷剂混合物的粘度在50℃、3-4℃×105N/mm压力下不得低于原润滑油的一半。制冷剂与润滑油(不超过10%)混合物在冷冻机运行的***温度下应稳定、不分层。用于冰箱压缩机的润滑油具有更高的稳定性,因为使用中不可能去观察油的变情况并进行更换,即油品要与电冰箱同寿命。
空压机油的选择一般要考虑往复式空压机油和回转式空压机油和回转式空压机油。对于空压机的排期温度高时可选择优质空压机油或合成空压机油。空压机油时间一般以1000小时-6000小时。
50 ° C viscosity 25-35m/S, high wear resistance and low freezing point (-38 ° C to -40 ° C) are required. Refrigerant dissolved in oil will reduce the viscosity of oil, so the viscosity of oil-refrigerant mixture at 50 ° C, 3-4 ° C × 105N/mm pressure should not be less than half of the original oil. The mixture of refrigerant and lubricating oil (not more than 10%) shall be stable and unstratified at the lowest operating temperature of the refrigerator. The lubricating oil used for refrigerator compressor has higher stability, because it is impossible to observe the oil changes and change, that is, the oil to the same life as the refrigerator. The selection of air compressor oil generally want to consider reciprocating air compressor oil and rotary air compressor oil and rotary air compressor oil. For air compressor row high temperature can choose high-quality air compressor oil or synthetic air compressor oil. Air compressor oil time in general to 1000 hours-6000 hours.
