谷轮涡旋压缩机缺油故障的预防以及解决方法
我们知道，制冷压缩机缺油运行，对其本身的造成的损伤是无法逆转的。这条规则，对于谷轮涡旋压缩机同样适用。本文中我们将以谷轮ZB38KQ-TFD-558为例来讲解。，涡旋压缩机内部缺油长时间会导致机构部和各摩擦副过热，导致轴承烧结、抱轴；即使短时间缺油也会导致机构部和各摩擦副异常磨损，导致振动、噪音大。
We know that the compressor compressor running without oil, the damage
to its own can not be reversed. This rule is also applicable to the
scroll compressor. In this paper, we will take Valley wheel
ZB38KQ-TFD-558 as an example to explain. First of all, the scroll
compressor internal oil long time will lead to overheating mechanism and
the side friction, sintering, lead to bearing axle; even for a short
time lack of oil can also cause the friction mechanism and lead to
abnormal wear, vibration, noise.
以谷轮ZB38KQ-TFD-558为例，循环量在ARI工况下约为330kg/h，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机器中，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。
Take the wheel ZB38KQ-TFD-558 as an example, the circulation volume is
about 330kg/h under the ARI condition, and the compressor will
discharge a little refrigerator oil when the refrigerant is discharged.
Even if only 0.5% of the oil rate, if the oil can not return to the
machine through the system cycle, then in 50 minutes you can bring all
the oil out of the compressor, in about 2~5 hours, the compressor will
burn out.
预防方法： 1、确保排出压缩机的冷冻机油回到压机内；2、减少压机的上油率。（压机频繁启动不利于回油。）
Preventive measures: 1. Ensure that the refrigerator oil of the
compressor is returned to the press; 2, reduce the oil rate of the
compressor. (press starts frequently, which is bad for oil return) 上一篇压缩机排气过热的原因下一篇压缩机常见故障原因解析 |
