空壓(yā)機轉子是高速(sù)轉動的，而端面(mian)是靜止，它們之(zhi)間存在有一定(ding)💃的間隙，而壓縮(suō)機功率越大所(suǒ)調的間隙也會(huì)增大。壓縮機轉(zhuan)子在裝配時很(hěn)重要的一步就(jiu)是調節其間隙(xi)，調大的話影響(xiǎng)壓縮機排💋氣量(liàng)，小的話容易摩(mo)擦發生高溫現(xiàn)象。螺杆壓縮機(ji)的🔱排端間隙是(shi)是設計者在設(shè)計的時候确定(dìng)了的。一般間隙(xì)是根據機器的(de)大🈲小、運行工況(kuang)、轉子及其缸體(ti)的材料🏃🏻等因素(su)定的。間隙隻要(yào)在一定的範🔴圍(wéi)内，不會影響機(ji)器的正常運行(háng)。

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.


如果空壓機機(ji)頭使用多年後(hòu)需要大修，維修(xiū)時最好是能🔱從(cong)制🌈造廠商那了(le)解該機頭的間(jian)隙範圍，而且最(zui)✨好是能在拆機(jī)器的時候測式(shi)該機器準确的(de)間隙值，安裝的(de)⛱️時候盡量保證(zhèng)這個間❌隙值。當(dang)然，各個廠家的(de)結構不一樣,間(jian)隙調整也有區(qū)😄别,要具體🙇‍♀️問題(tí)具體分析。如果(guǒ)所說的機頭故(gu)障屬于工況環(huan)㊙️境導緻，可以🙇‍♀️通(tong)過惡劣工況下(xià)用空氣過濾器(qi)，改善運行環境(jìng)🛀，從源頭呵護主(zhu)機，降低運🤞行成(chéng)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.



螺杆空壓機(jī)主機的進、排氣(qi)端面間隙，主要(yào)是考慮密封腔(qiāng)中的各個熱膨(péng)脹所引起的情(qíng)況，因此留有不(bu)同❓間隙❌。此外，又(yòu)因♊排氣端的受(shou)力大于進氣端(duan)，所以在排氣端(duān)用了止推軸承(cheng)。排氣端間隙過(guò)大，影響壓縮效(xiao)率；過小，熱膨脹(zhàng)間隙也要必須(xu)保證。這時，也要(yao)考慮到軸承的(de)遊隙。在維修主(zhu)機時，可以适當(dāng)放寬一點，主要(yào)是保證正常運(yun)轉。轉子與機殼(ke)之間的間隙，大(dà)體上同上。螺杆(gǎn)主機是精密部(bu)件，要充分掌握(wo)💞相關維修技術(shù)，才能進行很好(hao)地維護✌️。最後，将(jiang)維修好的主機(ji)進行相關的檢(jian)查，再按部就班(bān)地🌈進行總裝試(shi)車後投入運行(hang)。

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.
