谷輪渦旋壓縮機缺油故障的預防以及解決方法
我們知道，制冷壓縮機缺油運行，對其本身的造成的損傷是無法逆轉的。這條規則，對于谷輪渦旋壓縮機同樣適用。本文中我們將以谷輪ZB38KQ-TFD-558為例來講解。，渦旋壓縮機內部缺油長時間會導致機構部和各摩擦副過熱，導致軸承燒結、抱軸；即使短時間缺油也會導致機構部和各摩擦副異常磨損，導致振動、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.
以谷輪ZB38KQ-TFD-558為例，循環量在ARI工況下約為330kg/h，壓縮機在排出冷媒時，也會排出微量的冷凍機油。即使只有0.5%的上油率，如果油不能通過系統循環回到機器中，則在50分鐘就可以將壓縮機內的油全部帶出，大約在2～5小時內壓縮機將會燒壞。
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.
預防方法： 1、確保排出壓縮機的冷凍機油回到壓機內；2、減少壓機的上油率。（壓機頻繁啟動不利于回油。）
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)
