空壓機(jī)轉(zhuǎn)子間隙調(diào)節(jié)依據(jù)標(biāo)準(zhǔn)淺議
2019-02-23 10:34:07 點(diǎn)擊：
空壓機(jī)轉(zhuǎn)子是高速轉(zhuǎn)動(dòng)的，而端面是靜止，它們之間存在有一定的間隙，而壓縮機(jī)功率越大所調(diào)的間隙也會(huì)增大。壓縮機(jī)轉(zhuǎn)子在裝配時(shí)很重要的一步就是調(diào)節(jié)其間隙，調(diào)大的話影響壓縮機(jī)排氣量，小的話容易摩擦發(fā)生高溫現(xiàn)象。螺桿壓縮機(jī)的排端間隙是是設(shè)計(jì)者在設(shè)計(jì)的時(shí)候確定了的。一般間隙是根據(jù)機(jī)器的大小、運(yùn)行工況、轉(zhuǎn)子及其缸體的材料等因素定的。間隙只要在一定的范圍內(nèi)，不會(huì)影響機(jī)器的正常運(yùn)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(jī)機(jī)頭使用多年后需要大修，維修時(shí)最好是能從制造廠商那了解該機(jī)頭的間隙范圍，而且最好是能在拆機(jī)器的時(shí)候測(cè)式該機(jī)器準(zhǔn)確的間隙值，安裝的時(shí)候盡量保證這個(gè)間隙值。當(dāng)然，各個(gè)廠家的結(jié)構(gòu)不一樣,間隙調(diào)整也有區(qū)別,要具體問(wèn)題具體分析。如果所說(shuō)的機(jī)頭故障屬于工況環(huán)境導(dǎo)致，可以通過(guò)惡劣工況下用空氣過(guò)濾器，改善運(yùn)行環(huán)境，從源頭呵護(hù)主機(jī)，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.
螺桿空壓機(jī)主機(jī)的進(jìn)、排氣端面間隙，主要是考慮密封腔中的各個(gè)熱膨脹所引起的情況，因此留有不同間隙。此外，又因排氣端的受力大于進(jìn)氣端，所以在排氣端用了止推軸承。排氣端間隙過(guò)大，影響壓縮效率；過(guò)小，熱膨脹間隙也要必須保證。這時(shí)，也要考慮到軸承的游隙。在維修主機(jī)時(shí)，可以適當(dāng)放寬一點(diǎn)，主要是保證正常運(yùn)轉(zhuǎn)。轉(zhuǎn)子與機(jī)殼之間的間隙，大體上同上。螺桿主機(jī)是精密部件，要充分掌握相關(guān)維修技術(shù)，才能進(jìn)行很好地維護(hù)。最后，將維修好的主機(jī)進(jìn)行相關(guān)的檢查，再按部就班地進(jìn)行總裝試車(chē)后投入運(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.
