mfundo yogwirira ntchito
Kudalira ma rotor aamuna ndi aakazi omwe amayenda ndikuyenda, voliyumu pakati pa mano owoneka ngati "V" opangidwa ndi mano awo, ma groove a mano ndi khoma lamkati la thumba limasintha nthawi ndi nthawi kuti amalize kuyamwa gasi mufiriji- compression-kutulutsa ntchito ndondomeko
Njira yogwiritsira ntchito screw compressor
Zofunikira za screw compressor
1) Kugwira ntchito mosiyanasiyana kuzirala kwapakatikati, magawo osavala pang'ono, omwe amathandizira kuti magwiridwe antchito azitha kugwira ntchito, kudalirika kwambiri komanso kuchita bwino;2) mkulu processing mwatsatanetsatane, mtengo wapamwamba, ndi phokoso lalikulu;3) Kuthamanga kwambiri kwapang'onopang'ono, Palibe piston-mtundu wa hydraulic shock ndi centrifugal surge phenomenon:
4) Ndi njira ya jakisoni wamafuta, mafuta ochulukirapo amafunikira kubayidwa ndipo zida zothandizira zofananira ziyenera kukhala ndi zida.
Screw compressor application industry
Screw air compressor akhala akugwiritsidwa ntchito kwambiri m'mafakitale amakono ndi migodi, makamaka pamakina, zitsulo, kupanga magetsi, kupanga zombo zamagalimoto, nsalu, mankhwala, petrochemicals, zamagetsi, kupanga mapepala, chakudya ndi mafakitale ena.
Ubwino wa ma compressor otseguka
(1) Compressor imasiyanitsidwa ndi mota, kotero kuti kompresa itha kugwiritsidwa ntchito mosiyanasiyana
2) Compressor yemweyo amatha kusintha mafiriji osiyanasiyana.Kuphatikiza pa kugwiritsa ntchito mafiriji a halogenated hydrocarbon, ammonia amathanso kugwiritsidwa ntchito ngati firiji posintha zida za mbali zina.(3) Malinga ndi refrigerants osiyana ndi zikhalidwe ntchito , okonzeka ndi Motors osiyana mphamvu.
Zochitika Zachitukuko ndi Zotsatira za Kafukufuku
Njira yosinthira kuchuluka kwa voliyumu yamkati imagwiritsidwa ntchito;(1
(2) Kuponderezedwa kwa magawo awiri a makina amodzi kumatengedwa;
(3) Yambitsani miniaturization ya screw compressor.

Mawonekedwe:
(1) Ma rotor aamuna ndi aakazi a kompresa amatengera mano 6:5 kapena 7:5
(2) Cholekanitsa mafuta chimaphatikizidwa ndi injini yayikulu
(3) Galimoto yomangidwamo imakhazikika ndi gasi wafiriji (4) Mafuta opatsa mphamvu
(5) Makina ozizira opanda mafuta
Chifukwa cha kulera:
Pamene zinthu zogwirira ntchito za mpweya woziziritsidwa ndi kutentha kwa mpweya zimakhala zoipa kwambiri, kutentha kwa mpweya wotulutsa mpweya ndi mafuta odzola kapena kutentha kwa injini yomwe imapangidwira kumakhala kokwera kwambiri pamene kupanikizika kwa condensing kuli kwakukulu komanso kuthamanga kwa evaporation. otsika, zomwe zipangitsa kuti chipangizo chachitetezo chizigwira ntchito komanso kompresa kuyimitsa.Pofuna kuonetsetsa kuti kompresa ikugwira ntchito, imagwira ntchito mkati mwa malire ogwirira ntchito ndipo imatha kukhazikika ndi kupopera mbewu mankhwalawa mufiriji.
olekanitsa angapo mafuta
a) Chosiyanitsa mafuta chopingasa b) Cholekanitsa mafuta choyima c) Cholekanitsa mafuta chachiwiri

Fyuluta yolowetsa ndiye fyuluta yofunika kwambiri mu kompresa
Fumbi ndilomwe limapangitsa injini kuvala kwambiri ndipo limatha kuchepetsa kwambiri moyo wa zinthu za compressor, zolekanitsa mafuta ndi mafuta a compressor.
Ntchito yayikulu ya fyuluta ya mpweya wowuma ndikuwonetsetsa kuti zida za injini ndi kompresa zili ndi chitetezo chokwanira kuti zisawonongeke pansi pa fumbi lomwe lingawonekere.

Kufunika kwa Makina Olekanitsa Mafuta a Compressor
Mafuta a Compressor, omwe amagwiritsidwa ntchito makamaka kuti athetse kutentha komwe kumapangidwa panthawi yoponderezedwa, amafunika kulekanitsidwanso ndi mpweya.Mafuta aliwonse opaka mafuta osakanizidwa mumpweya woponderezedwa amayambitsa kuipitsidwa kwamafuta ndikupangitsa kuchulukira kwa netiweki ya mpweya, condenser ndi condensing process.
Kuchuluka kwa mafuta otsalira kumawonjezera kugwiritsa ntchito mafuta opaka mafuta komanso mtengo wake wonse, ndikupeza mpweya wochepa kwambiri.
Mafuta ochepa otsalira amatanthauzanso kuti mafuta ochepa amalowa mu ngalande ya condensate, yomwe ilinso yabwino kwa chilengedwe.
Mafuta opaka mafuta amasiyanitsidwa koyamba ndi mpweya kuchokera ku mpweya wolandira mpweya ndipamwamba kwambiri ndi cholekanitsa cha centrifugal.Mafuta opaka mafuta amagwera pansi pa wolandira chifukwa cha mphamvu yokoka.

Njira zowonetsetsera moyo wautali wantchito wa olekanitsa mafuta
Fumbi lochuluka, mankhwala akale amafuta, kuipitsidwa kwa mpweya kapena kuvala kungachepetse moyo wa olekanitsa mafuta.
Pofuna kuonetsetsa moyo wabwino wa utumiki wa olekanitsa mafuta, njira zotsatirazi ziyenera kuchitidwa.
Nthawi zambiri, kudzikundikira tinthu olimba mu wosanjikiza bwino kulekana kudzachititsa kuwonjezeka kuthamanga kusiyana, potero kuchepetsa moyo utumiki wa olekanitsa mafuta.

Fumbi lomwe limalowa mumafuta a kompresa limatha kuchepetsedwa ndikusintha kwanthawi yake zosefera za mpweya ndi mafuta komanso powona kusintha kwamafuta.
Kusankha mafuta oyenera ndikofunikanso kwambiri.Gwiritsani ntchito mafuta ovomerezeka, oletsa kukalamba komanso osamva madzi.
Kugwiritsira ntchito mafuta osayenera omwe alibe mphamvu yokwanira ya antioxidant, ngakhale kwa nthawi yochepa, angapangitse mafuta kukhala odzola ngati odzola mu kachulukidwe ndi kutseka cholekanitsa mafuta chifukwa cha kuchuluka kwa matope.
Kukalamba kofulumira kwa mafuta kumayamba chifukwa cha kutentha kwambiri kwa ntchito.Choncho, chisamaliro chokwanira chiyenera kuperekedwa pakupereka mpweya wozizira wokwanira ndi kuchotsa zinyalala mu ozizira nthawi.
Mukasintha mafuta, mafuta onse ogwiritsidwa ntchito ayenera kukhetsedwa kuti asawononge mafuta otsalira komanso kusagwirizana kwamafuta awiriwo.

Chiyambi cha Makina Osefera Mafuta
Ntchito ya fyuluta yamafuta ndikuchotsa zonyansa zonse zomwe zimapangitsa kuti pakhale mafuta pamakina, koma nthawi yomweyo osalekanitsa zowonjezera zowonjezera.
Fumbi ndi zonyansa mu mafuta a kompresa zidzachulukana pakati pa choyikapo cha kompresa element ndi shaft yozungulira, zomwe zipangitsa kuti shaft yozungulira iwonongeke komanso kutsika kwa kompresa.
Mafuta a Compressor amagwiritsidwanso ntchito kudzoza mayendedwe a zinthu za kompresa, kotero dothi ndi zonyansa zimatha kuwononganso zodzigudubuza.Kuvala kompresa kumawonjezera kukhudzana kwa shaft ndipo kumabweretsa kuchepa kwa ntchito ya kompresa ndikufupikitsa moyo wazinthu za kompresa
Kuwonongeka kwina kwa ma rollers onyamula kungayambitse kuphulika kwa casing ndi kuwononga kwathunthu kwa compressor element.
Kuwunika kwa zolakwika zomwe wamba Kutentha kwa rotor ndikokwera kwambiri
