Zifukwa za kuchuluka kwa mafuta mu mpweya woponderezedwa wa screw air compressor
Mafuta ndi gasi olekanitsa khalidwe
Chitoliro chobwezera mafuta kapena valavu yoyang'anira mafuta yatsekedwa
Kuthamanga kwa valve yokonza ma valve ndikotsika kwambiri
Chachinayi: kugwiritsa ntchito kupanikizika kumakhala kochepa kwambiri
Chachisanu: mtundu wa thovu lamafuta
Valavu yokhazikika yokhazikika imayikidwa mokulirapo kapena yofanana ndi 0.40Mpa kuti itulutse mpweya,
Ndi bwino kugwiritsa ntchito chiyambi (chomangidwa) mafuta ndi gasi olekanitsa pachimake.Kaya malo a chitoliro chobwezera mafuta achotsedwa kapena ayi zimadalira chitoliro chobwezera mafuta ndi sefa kapena valavu yowunikira mafuta.
Kuthamanga kwa mpweya wa compressor kukonza ma valve okwera kwambiri kumatha kutulutsanso mafuta ambiri mumpweya woponderezedwa (kuthamanga kwapang'onopang'ono ndikotsika kwambiri), izi zimachitika nthawi zambiri.
Chifukwa chiyani mafuta opaka mafuta amayenera kusinthidwa pafupipafupi?
Mafuta opaka mafuta akagwiritsidwa ntchito kwa nthawi inayake, ayenera kusinthidwa nthawi zonse chifukwa cha zinthu zotsatirazi zomwe zimakhudza ubwino wa mafuta: 1. Zitsulo zometa zachitsulo zimachotsedwa pamtunda chifukwa cha kuvala;2. Fumbi ndi zinthu zina zolimba zomwe zimabweretsedwa ndi mpweya: 3. Mchenga woumba umene sunachotsedwe mosamala poponya;4. Chosanjikiza cha utoto pagawo la makina chimachotsedwa;
5. Mafuta opangira mafuta amatulutsa chinyezi panthawi yozizira ndipo mafuta amawonongeka: 6. Kutentha ndi zina za mafuta odzola muzitsulo zozungulira zimachepetsa pang'onopang'ono ntchito ya mafuta.
Ma sundries omwe tawatchulawa ndi osavuta kupanga ma abrasive phala ma analogue mu mafuta opaka mafuta, kuwononga mafuta opaka mafuta, ndikufulumizitsa kuphulika kwa chipwirikiti cha makina mwamphamvu.Chifukwa chake, ngati mafuta opaka pamakina amawonongeka pang'onopang'ono kuzizindikiro zotsatirazi mukamagwiritsa ntchito, ayenera kusinthidwa ndi mafuta atsopano: ngati palibe zida zowunikira ndipo sizingawunikidwe, m'malo mwake ndi mafuta atsopano maola 2000 mpaka 3000 aliwonse.Ndipo yeretsani mosamala zida zoperekera mafuta ndi malo aliwonse opaka mafuta.
Zomwe zingakhudze kusamuka kwenikweni kwa screw compressor
Kusamuka kwamalingaliro kwa screw compressor kumadalira kuchuluka kwa dzino, kuchuluka kwa mano ndi liwiro.Voliyumu yapakati-dzino imatsimikiziridwa ndi kukula kwa geometric kwa rotor.Kwa ma compressor, zifukwa zomwe zingapangitse kusamuka kwenikweni kukhala kochepa kuposa kusamutsidwa kwamalingaliro ndi: 1) Kutayikira.Palibe kukhudzana pakati pa ma rotor ndi pakati pa rotor ndi casing panthawi yogwira ntchito, ndipo kusiyana kwina kumasungidwa, kotero kutuluka kwa mpweya kudzachitika.Pamene mpweya wochuluka wa mpweya utsikira ku chitoliro choyamwa ndi popopopopopopopopopopera, mphamvu yotulutsa mpweya idzachepetsedwa.Pofuna kuchepetsa kutayikira, mano osindikizira amapangidwa pamwamba pa dzino la rotor yoyendetsedwa, ma groove osindikizira amatsegulidwa pazu la dzino la rotor yoyendetsa, ndipo mano osindikizira opangidwa ndi mphete kapena mikwingwirima amakonzedwanso kumapeto kwa nkhope.Ngati mizere yosindikizirayi yavala, kutayikirako kumawonjezeka ndipo kuchuluka kwa mpweya kumachepa: 2) Kupuma mpweya.The screw Compressor ndi volumetric compressor, ndipo voliyumu yoyamwa imakhala yosasinthika.Kutentha koyamwa kukakwera, kapena kukana kwa payipi kumakhala kwakukulu kwambiri kuti kuchepetse kuthamanga kwa mpweya, kuchuluka kwa mpweya kumachepa, ndipo mtundu wa gasiwo umachepa motere.Kusamuka:

3) Kuzizira kwenikweni.Kutentha kwa gasi kudzawonjezeka panthawi yoponderezedwa, ndipo kutentha kwa rotor ndi casing kudzawonjezeka moyenerera.Choncho, panthawi yoyamwa, mpweya udzatenthedwa ndi rotor ndi casing ndi kukulitsa, kotero kuti voliyumu yoyamwa idzachepetsedwa moyenerera.Zina mwa ma rotor a screw air compressor zimakhazikika ndi mafuta, ndipo chosungiracho chimakhazikika ndi madzi.Chimodzi mwa zolinga zake ndi kuchepetsa kutentha kwake.Pamene kuzizira sikuli bwino, kutentha kumakwera ndipo mphamvu yotulutsa mpweya idzachepa;
4) Liwiro.Kusuntha kwa screw compressor ndikofanana mwachindunji ndi liwiro.Liwiro nthawi zambiri limasintha ndi voteji ndi mafupipafupi a gridi yamagetsi.Pamene voteji imachepetsedwa (kwa asynchronous motors) kapena mafupipafupi afupika, liwiro lidzatsika, kuchepetsa mphamvu ya mpweya.
