空壓(yā)機轉子是(shi)高速轉動(dong)的，而端面(mian)是靜止，它(ta)們之間存(cún)在⭕有一定(ding)的間隙，而(ér)壓縮機功(gōng)率越大所(suo)調的間隙(xì)也會增大(da)。壓縮機轉(zhuǎn)子在裝配(pèi)時很重要(yào)的一步就(jiù)是調節其(qí)間隙，調大(dà)的話影響(xiang)壓縮機排(pai)氣量，小的(de)話🌈容易摩(mo)擦🌈發生高(gao)溫現象。螺(luo)杆壓縮機(ji)的排端間(jiān)隙是是設(she)計者🔴在設(shè)計的時✨候(hòu)确定了的(de)。一般間隙(xi)是根據機(jī)器的💃大⛱️小(xiao)、運行工況(kuang)、轉💛子及其(qí)缸體的材(cai)料💯等因素(su)定的。間隙(xì)隻要在一(yī)定的範圍(wei)内，不會影(ying)響機器的(de)正常運行(hang)。

The air compressor rotor rotates at high speed, while the end face is stationary. There is a certain gap between them, and the clearance adjusted by the higher the compressor power is, the larger the clearance will be. When the compressor rotor is assembled, it is very important to adjust its clearance. If it is increased, it will affect the compressor exhaust volume. If it is small, it will easily cause high temperature friction. The end clearance of screw compressor is determined by the designer at the time of design. General clearance is determined by the size of the machine, operating conditions, materials of the rotor and its cylinder. As long as the clearance is within a certain range, it will not affect the normal operation of the machine.


如果空壓(ya)機機頭使(shǐ)用多年後(hou)需要大修(xiū)，維修時最(zui)好是能從(cóng)制♻️造廠商(shāng)那了解該(gāi)機頭的間(jian)隙範圍，而(ér)且最好是(shì)✌️能在拆機(ji)🚩器的時候(hou)測式該機(jī)器準确的(de)間隙值，安(an)裝的時候(hou)盡量保證(zheng)這個間隙(xi)值。當然，各(gè)☎️個廠家的(de)結構不一(yi)樣,間隙調(diào)整也有區(qū)别,要具體(tǐ)🛀問題具體(ti)分析。如果(guǒ)所說🔱的機(ji)頭故障💘屬(shǔ)于工況環(huan)✌️境導緻，可(ke)以通☀️過惡(e)劣工況下(xia)用空氣過(guo)濾器，改善(shàn)運行環境(jìng)，從源頭呵(he)護主機，降(jiàng)低運💚行成(cheng)本。

If the air compressor head needs to be overhauled after many years of use, it is better to know the clearance range of the head from the manufacturer when repairing, and it is better to measure the accurate clearance value of the machine when disassembling the machine, and try to ensure the clearance value when installing. Of course, the structure of each manufacturer is different, gap adjustment is also different, specific issues need to be analyzed. If the said nose failure is caused by working conditions, the operating environment can be improved by using air filters under bad working conditions, and the main engine can be cared for from the source to reduce operating costs.

The inlet and exhaust end clearance of the main engine of screw air compressor is mainly caused by the thermal expansion in the sealing chamber, so there are different clearances. In addition, the thrust bearing is used at the exhaust end because the force at the exhaust end is greater than that at the intake end. Excessive clearance at the exhaust end affects the compression efficiency; too small, the thermal expansion clearance must also be guaranteed. At this time, bearing clearance should also be taken into account. In the maintenance of the main engine, we can relax a little, mainly to ensure normal operation. The clearance between the rotor and the casing is roughly the same. The main screw machine is a precise part. Only by fully mastering the relevant maintenance technology, can it be well maintained. Finally, the repaired main engine is inspected and put into operation after commissioning.
