空壓機轉子是高[Gao]速[Su]轉動的，而端面是靜止，它們(Men)之間存在有一定的間隙，而(Er)壓縮機功率(Lü)越大(Da)所調的間隙也[Ye]會增[Zeng]大。壓縮機轉子在裝配時很重要的一步[Bu]就是調節其間隙，調大的話影[Ying]響壓[Ya]縮機排(Pai)氣[Qi]量，小的話容易[Yi]摩擦發生高(Gao)溫現(Xian)象。螺杆壓縮[Suo]機的排端間隙是是設計者在[Zai]設計的時(Shi)候确(Que)定了的。一般[Ban]間隙是根據(Ju)機器的大小、運行工況、轉子及其缸(Gang)體的材料等因素定[Ding]的。間隙隻(Zhi)要在一定的範圍内，不會影(Ying)響[Xiang]機器的正常運[Yun]行。

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.


如果空壓機機頭使用多[Duo]年[Nian]後需要大修，維[Wei]修時最[Zui]好是能從制(Zhi)造廠商那了解該機[Ji]頭(Tou)的間隙範圍，而(Er)且最好是能[Neng]在拆機(Ji)器(Qi)的時候測[Ce]式該(Gai)機器準确的間隙值，安裝[Zhuang]的時候盡(Jin)量保(Bao)證這(Zhe)個間隙值。當然，各個廠家的結構不一樣,間(Jian)隙調整也有區别,要具體問題具體[Ti]分[Fen]析。如果所說的機頭[Tou]故障(Zhang)屬于工[Gong]況環境導緻，可以(Yi)通過惡劣工[Gong]況下用空氣過濾器，改善運行環(Huan)境，從[Cong]源[Yuan]頭呵護主機，降低[Di]運行成本。

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[Kong]壓(Ya)機主機的進、排氣端面間隙，主要是考慮(Lü)密封腔中的各個熱[Re]膨脹所引起的情況，因此[Ci]留有不同間(Jian)隙。此[Ci]外，又因排氣端的受力大于進氣(Qi)端，所以在排氣端用了止(Zhi)推軸承。排氣[Qi]端間隙[Xi]過大，影響壓縮效率；過小，熱(Re)膨(Peng)脹間隙也[Ye]要必(Bi)須保證。這時，也要考慮[Lü]到軸承(Cheng)的遊隙。在維修(Xiu)主[Zhu]機時，可以适當放寬一點，主[Zhu]要是保證正常運轉。轉子與機(Ji)殼之間的間隙，大體上同上。螺杆主(Zhu)機是精密部件，要充(Chong)分掌握相關(Guan)維修技術，才能進行很[Hen]好地維護。最後，将維修好的主[Zhu]機進行相(Xiang)關的檢查，再(Zai)按部就[Jiu]班地進行總裝試車後投入運[Yun]行。

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.
