空(kōng)壓機轉子是(shi)高速轉動的(de)，而端面是靜(jìng)止，它們之間(jiān)存在有一定(ding)♻️的間隙，而壓(ya)縮機功率越(yuè)大所調的間(jiān)隙也會增大(dà)。壓縮機🤩轉子(zi)在裝配時很(hěn)重要的一步(bù)就是調節其(qí)間隙，調大的(de)話影響壓縮(suō)機排⚽氣量，小(xiao)的話容易摩(mo)擦發生高溫(wen)現象。螺杆壓(ya)縮機的排端(duan)間隙是是設(she)計者在設計(jì)的時候确定(dìng)了的。一般間(jian)隙是🆚根據機(ji)器的大小、運(yun)行工況、轉子(zi)及其缸體的(de)✂️材料等因素(su)定的。間隙🈲隻(zhī)要在一定的(de)範圍内，不會(hui)影響機器的(de)正常運行。
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(ru)果空壓機機(ji)頭使用多年(nian)後需要大修(xiu)，維修時最好(hǎo)是能從制造(zao)廠商那了解(jiě)該機頭的間(jian)隙範圍，而且(qiě)最好是♋能在(zai)拆機✍️器的時(shi)候測式該機(ji)器準确的間(jiān)隙值，安裝的(de)時候盡量保(bǎo)證這個間隙(xi)值。當然，各個(gè)廠家的結構(gou)不一樣,間隙(xì)調整也有區(qu)别,要具體問(wen)題具體分析(xi)。如果所說的(de)機頭故障屬(shǔ)于工況環境(jìng)導緻，可以通(tōng)過惡劣工況(kuang)下用空氣過(guo)濾器，改善運(yùn)行環境⭐，從源(yuan)頭呵護主❗機(ji)，降低運行成(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.
螺杆空壓(ya)機主機的進(jìn)、排氣端面間(jian)隙，主要是考(kǎo)慮密封腔🤟中(zhōng)的各個熱膨(peng)脹所引起的(de)情況，因此留(liú)有不同間隙(xi)。此外，又因排(pái)氣端的受力(lì)大于進氣端(duan)，所以在排氣(qi)端用了止推(tuī)🐉軸承。排📞氣端(duān)間隙過大，影(ying)響壓縮效率(lǜ)；過小，熱膨🍓脹(zhang)間隙也🛀要必(bi)須保♉證。這時(shí)，也要考慮到(dào)軸承的遊隙(xì)。在維修主機(ji)時，可以适當(dāng)放寬一點，主(zhu)要是💛保證正(zheng)常運轉🌈。轉子(zǐ)與機殼之間(jiān)的間隙，大體(ti)上同上。螺杆(gǎn)主機是精密(mì)部件，要充分(fèn)掌握相關維(wei)修技術，才☀️能(neng)進行很好地(di)維護🔞。最後，将(jiang)維修好的主(zhu)機進行相關(guan)的檢查，再按(an)部就班地進(jìn)行總裝試車(chē)後投入運行(háng)。
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.
