我們知道，制冷壓縮機(jī)缺油運(yùn)行，對(duì)其本身的造成的損傷是無(wú)法逆轉(zhuǎn)的。這條規(guī)則，對(duì)于谷輪渦旋壓縮機(jī)同樣適用。本文中我們將以谷輪ZB38KQ-TFD-558為例來(lái)講解。，渦旋壓縮機(jī)內(nèi)部缺油長(zhǎng)時(shí)間會(huì)導(dǎo)致機(jī)構(gòu)部和各摩擦副過(guò)熱，導(dǎo)致軸承燒結(jié)、抱軸；即使短時(shí)間缺油也會(huì)導(dǎo)致機(jī)構(gòu)部和各摩擦副異常磨損，導(dǎo)致振動(dòng)、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(huán)量在ARI工況下約為330kg/h，壓縮機(jī)在排出冷媒時(shí)，也會(huì)排出微量的冷凍機(jī)油。即使只有0.5%的上油率，如果油不能通過(guò)系統(tǒng)循環(huán)回到機(jī)器中，則在50分鐘就可以將壓縮機(jī)內(nèi)的油全部帶出，大約在2～5小時(shí)內(nèi)壓縮機(jī)將會(huì)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(yù)防方法： 1、確保排出壓縮機(jī)的冷凍機(jī)油回到壓機(jī)內(nèi)；2、減少壓機(jī)的上油率。（壓機(jī)頻繁啟動(dòng)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)
