空壓(yā)機轉子是高速轉(zhuǎn)動的，而端面是靜(jing)止，它們之間存在(zài)有✔️一定的間隙，而(ér)壓縮機功率越大(da)所調的間隙也會(huì)增大。壓縮機轉子(zǐ)🏃‍♂️在裝配時很重要(yao)的一步就是調節(jie)其間隙，調大的話(huà)影響壓縮機排氣(qì)量，小的話容易摩(mo)擦發生高溫現象(xiàng)。螺杆壓縮機的排(pái)端間隙🌈是是設計(ji)者🌈在設計的時🆚候(hou)确定了的。一般間(jian)隙是根據機器的(de)🥵大小、運行工況、轉(zhuan)子及其缸體的材(cái)料🚶‍♀️等因素定的。間(jiān)隙隻要在📐一定的(de)範圍内，不會影響(xiǎng)機器的正常運行(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.


如果空壓機機頭(tou)使用多年後需要(yao)大修，維修時最好(hǎo)是能從制💋造廠商(shāng)那了解該機頭的(de)間隙範圍，而且最(zuì)好是能在拆機器(qì)的時候測式該機(ji)器準确的間隙值(zhí)，安裝的時候盡量(liàng)保證這個間隙值(zhí)。當然，各個廠家的(de)結構不一樣,間隙(xi)調整也有區☂️别,要(yao)具體🌈問題具體分(fen)析。如果所說的機(ji)頭故障屬于工況(kuàng)環境導緻，可以通(tōng)過惡劣工況下用(yòng)空氣過濾器🌍，改善(shàn)運行環境，從源頭(tou)呵護主機，降低運(yùn)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.



螺杆空壓(ya)機主機的進、排氣(qi)端面間隙，主要是(shi)考慮密封腔中的(de)各個熱膨脹所引(yin)起的情況，因此留(liú)有👌不同間隙⛱️。此外(wài)🧑🏽‍🤝‍🧑🏻，又因💃排氣端的受(shòu)力大于進氣端，所(suǒ)以在排氣端用了(le)止推軸承。排💔氣端(duān)間🤩隙過大，影響壓(yā)縮效率；過小，熱膨(peng)脹間隙也要必須(xū)保證。這時，也⛹🏻‍♀️要考(kǎo)慮到軸承的遊隙(xi)。在維修主機時，可(kě)以适當放寬一點(dian)，主要是保證正常(chang)運轉。轉子與機殼(ké)之間的間隙，大體(tǐ)上同上🛀。螺杆主機(ji)是精密部件，要充(chōng)分掌握相關維修(xiu)技術，才🌏能進行很(hěn)好地維護🏒。最後，将(jiang)維修好的主機進(jìn)行相關的檢查，再(zài)按部就班地☀️進行(hang)㊙️總裝試車後投入(rù)運行。

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.
