涡旋制冷压缩机常见的缺油故障,解决方法都在这里了!

涡旋制冷压缩机常见的缺油故障

压缩机长时间缺油——机构部和各摩擦副过热,导致轴承烧结、抱轴。


压缩机短时间缺油——机构部和各摩擦副异常磨损,导致振动、噪音大。


一、如何保证适当的油量

压缩机在排出冷媒时,也会排出微量的冷冻机油。即使只有0.5%的上油率,如果油不能通过系统循环回到压缩机中。若以5HP为例,循环量在ARI工况下约为330kg/h,则在50分钟就可以将 压缩机内的油全部带出,大约在2~5小时内压缩机将会烧坏。因此为了确保压缩机运行不缺油,应该从以下二方面着手:

十二、压缩机高温损坏的主要原因

由于超范围使用、电源不正常、电机过载、制冷剂泄漏、冷凝压力太高等问题引起的电机高温、排气温度过高、润滑油焦糊等过热现象。 压缩机表面温度是判断压缩机是否过热的重要指标之一。如果表面温度超过135°C,一般认为压缩机已经处于严重过热状态;而如果表面温度低于120°C,压缩机温度正常。 电机发热量大   供电不正常会引起电机发热量增大,如:电压不稳、电压太低或太高、电压不平衡、缺相等都属于电源供电不正常。
