空(kōng)壓機(jī)轉子是高(gāo)速轉動(dòng)的(de)，而端面是靜止，它們(men)之間存在有一(yī)定的間隙，而壓縮機功率越大(dà)所調(diào)的間(jiān)隙也(yě)會增大。壓縮機轉(zhuǎn)子(zǐ)在裝配時(shí)很重要的一步(bù)就是調節其間(jiān)隙，調大的(de)話影(yǐng)響壓(yā)縮機排氣量，小的話容易(yì)摩擦發(fā)生高溫現象(xiàng)。螺杆(gǎn)壓縮機的(de)排端間隙(xì)是是(shì)設(shè)計者在(zài)設計(jì)的時候确(què)定了的。一般間(jiān)隙是根據機器(qì)的大(dà)小、運(yùn)行工(gōng)況、轉(zhuǎn)子及其缸(gāng)體的材料等因素定(dìng)的(de)。間隙隻(zhī)要在一定的範(fàn)圍内，不(bú)會影響(xiǎng)機器的正常運行。

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(rú)果空壓機(jī)機頭使(shǐ)用多年(nián)後需要大(dà)修，維(wéi)修時最好是能(néng)從制(zhì)造廠商那(nà)了解該機頭的間隙(xì)範(fàn)圍，而且(qiě)最好是(shì)能在拆機器(qì)的時候測(cè)式該機器準确的間隙(xì)值，安裝(zhuāng)的時候(hòu)盡量保(bǎo)證這(zhè)個間(jiān)隙值(zhí)。當然(rán)，各個(gè)廠家的結(jié)構不一樣(yàng),間(jiān)隙調整(zhěng)也有(yǒu)區别(bié),要具體問題具體分析。如(rú)果所說的機頭故障屬(shǔ)于(yú)工況(kuàng)環境(jìng)導緻，可以(yǐ)通過惡(è)劣工況(kuàng)下用空氣過濾(lǜ)器，改善運(yùn)行環(huán)境，從源(yuán)頭(tóu)呵護(hù)主機(jī)，降低運行(háng)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(yā)機主機的進、排(pái)氣端面(miàn)間隙，主(zhǔ)要是考慮密封(fēng)腔(qiāng)中的各個熱(rè)膨脹所引起的(de)情況(kuàng)，因此留有(yǒu)不同(tóng)間隙(xì)。此外(wài)，又因(yīn)排氣端的(de)受力(lì)大(dà)于進氣(qì)端，所(suǒ)以在排氣(qì)端用了(le)止(zhǐ)推軸(zhóu)承。排氣端間隙(xì)過大，影響(xiǎng)壓縮(suō)效率(lǜ)；過小，熱膨(péng)脹間(jiān)隙也(yě)要必須保證。這時，也(yě)要考(kǎo)慮(lǜ)到(dào)軸承(chéng)的遊(yóu)隙(xì)。在維修(xiū)主機時，可以适當放(fàng)寬一點，主要是保證(zhèng)正常(cháng)運轉(zhuǎn)。轉子與機(jī)殼之(zhī)間的間隙(xì)，大體上同上。螺(luó)杆主機是精(jīng)密部件，要充(chōng)分掌(zhǎng)握相關(guān)維(wéi)修技(jì)術，才能進行很(hěn)好地維護。最後(hòu)，将維(wéi)修好(hǎo)的主(zhǔ)機進行(háng)相關的檢查，再(zài)按部就(jiù)班地進行總裝試(shì)車(chē)後投入運(yùn)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.
