A, mu kulephera kwa compressor ya screw, utsi wotuluka ndi kulephera kwa mafuta ndiye wofala kwambiri, zomwe zimayambitsa kulephera kwa utsi ndi kulephera kwa mafuta pazinthu zazikulu ndi izi:
1. kuwonongeka kwa pakati pa mafuta
Pakugwira ntchito kwa screw compressor, pakati pa mafuta olekanitsa mafuta pamakhala kuwonongeka monga momwe zimakhalira ndi vuto losweka, lobowoka, kenako limataya ntchito ya mafuta ndi gasi. Izi zikutanthauza kuti, mapaipi otulutsa mpweya wosakanikirana ndi compressor omwe amadutsa mwachindunji, kenako mafuta ambiri ozizira salekanitsidwa, adzatulutsidwa ndi thupi la gasi, zomwe zimapangitsa kuti mafuta asamayende bwino.
2.kulephera kwa mzere wobwerera kwa mafuta
Pakugwira ntchito kwa screw compressor, chingwe chobwezera mafuta chimakhala ndi udindo wofunikira, pakati pa mafuta olekanitsa mkati ndi mkati mwa compressor zimapanga kusiyana kwa kuthamanga, monga momwe zimakhalira ndi kusiyana kwa kuthamanga uku, mzere wobwezera mafuta umayang'anira pakati pa mafuta olekanitsa pansi pa mafuta osonkhanitsidwa kubwerera ku compressor, mu ndondomeko yotsatira yopitilira, pitirizani kugwiritsa ntchito. Ngati chingwe chobwezera mafuta chatsekedwa, chasweka ndipo chayikidwa molakwika, sichidzatha kunyamula mafuta omwe asonkhanitsidwa pansi pa pakati pa mafuta olekanitsa kubwerera ku compressor, zomwe zimapangitsa kuti mafuta ambiri azisonkhana pansi, ndiye kuti gawo ili la mafuta lomwe silinatengedwe kubwerera ku compressor lidzatulutsidwa ndi mpweya, ndipo padzakhala chodabwitsa cha mafuta mu ndondomeko yotulutsa utsi.
3. Kulamulira kuthamanga kwa mpweya m'dongosolo kuli kotsika kwambiri
Pakugwira ntchito kwa screw compressor, kulamulira kuthamanga kwa dongosolo kumakhala kotsika kwambiri, zomwe zimapangitsa kuti mphamvu ya centrifugal mu separator ikhale yochepa kuposa mphamvu ya centrifugal yomwe ikufunika, ndiye kuti ntchito ya separator sidzawonetsedwa mokwanira, zomwe zimapangitsa kuti ulalo wotsatira mu separator core mafuta a gasi akhale okwera kwambiri, kupitirira malire ake olekanitsa, zomwe zimapangitsanso kuti kulekanitsa mafuta ndi gasi kusakwanire, mu njira yotulutsa utsi wa compressor ndi kulephera kwa mafuta.
4. kulephera kochepa kwa vavu yothamanga
Pakugwira ntchito kwa screw compressor, valavu yocheperako yokakamiza ndi kuonetsetsa kuti kayendetsedwe ka kuthamanga kwa dongosolo kakugwira ntchito pakagwa kupanikizika kochepa pamwambapa. Ngati vuto la kulephera kwa valavu yocheperako yokakamiza, ndiye kuti kupanikizika kochepa kwa dongosolo sikungatsimikizidwe, chifukwa cha mwayi wa zidazo ndi kugwiritsa ntchito gasi kwambiri, izi zimapangitsa kuti kuthamanga kwa dongosolo kukhale kochepa kwambiri, mzere wobwerera mafuta sungabwezeretse mafuta. Mafuta omwe asonkhanitsidwa pansi pa chimake cholekanitsa mafuta sangathe kubwerera ku compressor, adzatulutsidwa kuchokera ku compressor ndi mpweya wopanikizika, zomwe zimapangitsa kuti njira yotulutsira utsi ikhale yopanda kanthu komanso kulephera kwa mafuta.
5. compressor yolumikizira mafuta ozizira ndi yochuluka kwambiri
Musanayambe ntchito ya screw compressor, mafuta ozizira ochulukirapo amawonjezeredwa, kuposa kuchuluka kwa compressor, kenako compressor ikagwira ntchito, chifukwa mafuta amakhala okwera kwambiri, ngakhale kuti njira yolekanitsira mafuta ndi gasi zimasiyana, koma mu kutulutsa mpweya, gasiyo imagwiranso ntchito mu kuzirala kwa mafuta kupita ku kutulutsa mpweya, zomwe zimapangitsa kuti mafuta azituluka mu gasi, zomwe zimapangitsa kuti mafuta azituluka mu gasi, ndipo mafuta amalephera kutuluka.
6. Ubwino wa mafuta ozizira si woyenera
Compressor isanayambe kugwira ntchito, kuwonjezera mafuta ozizira osayenerera, kapena mafuta ozizira kwa nthawi yayitali kuposa nthawi yomwe ikugwiritsidwa ntchito, sikunathe kukwaniritsa zotsatira za kuzizira. Kenako pakugwira ntchito kwa compressor yozungulira, mafuta ozizira adataya ntchito yake, ndipo sangathe kuziziritsa kulekanitsa mafuta ndi gasi. Kenako mu ndondomeko yotulutsa utsi idzawonekera ndi kulephera kwa mafuta.
Chachiwiri, kufufuza zolakwika, njira zothetsera mavuto
Ngati compressor yapezeka ndi mafuta mu utsi, simuyenera kusokoneza zida mosazindikira, koma ziyenera kutengera zifukwa zomwe zili pamwambapa zowunikira, mogwirizana ndi njira kuyambira zosavuta mpaka zovuta zodziwira magawo a cholakwika. Izi zitha kuchepetsa nthawi yambiri yokonza ndi mphamvu ya anthu.
Pamene compressor yayamba bwino ndipo dongosolo likufika pa kuthamanga koyenera, tsegulani pang'onopang'ono valavu yotulutsira utsi, potseguka pake payenera kukhala kakang'ono momwe mungathere kuti mpweya wochepa utuluke. Pakadali pano, gwiritsani ntchito thaulo louma la pepala motsutsana ndi mpweya wotuluka, ngati thaulo la pepalalo lasintha mtundu wake nthawi yomweyo ndipo madontho a mafuta atayika, mutha kudziwa utsi wotulutsira utsi wa compressor ndi mafuta ochulukirapo kuposa muyezo. Malinga ndi kuchuluka kwa mafuta mu mpweya wotulutsira utsi ndi nthawi zosiyanasiyana, ndi zina zotero, chigamulo cholondola chingapangidwe pa gawo lomwe vuto lachitika.
Pamene kutsegula kwa valavu yotulutsira utsi kwawonjezeka, mpweya wotuluka umapezeka kuti ndi wokhuthala mosalekeza, zomwe zikusonyeza kuti mpweyawo uli ndi mafuta ambiri, kenako n’kuyang’ana kubwerera kwa mafuta ku galasi lowonera chubu chobwezera mafuta. Ngati mafuta owonera chubu chobwezera mafuta awonjezeka kwambiri, nthawi zambiri mafuta ozizira awonjezeredwa kwambiri pamaziko olekanitsa; ngati mafuta owonera chubu chobwezera mafuta awonjezeka, nthawi zambiri chubu chobwezera mafuta chasweka, ndipo chubu chobwezera mafuta chasweka.
Pamene valavu yotulutsa mpweya ikukula, valavu yotulutsa mpweya imakula kwambiri, ndipo kutsogolo kwa valavu yotulutsa mpweya imakula kwambiri, ndipo pakapita nthawi, valavu yotulutsa mpweya imakula bwino; pitirizani kukulitsa valavu yotulutsa mpweya, valavu yonse yotulutsa mpweya imatsegulidwa, kenako tsatirani njira yoyezera kuthamanga kwa mpweya, ngati valavu yotulutsa mpweya ikuwonetsa kuti kuthamanga kuli kotsika kuposa valavu yochepetsa kuthamanga, valavu yotulutsa mpweya imakula bwino ndipo mpweya umatuluka mosalekeza. Chochitika ichi chimachitika, vuto nthawi zambiri ndi kulephera kwa valavu yochepetsa kuthamanga.
Pamene shutdown yachibadwa, valavu yotulutsira mpweya yokha imayikidwa kuti itulutse utsi, ngati valavu yotulutsira mpweya yokhala ndi mafuta ambiri, zomwe zikusonyeza kuti valavu yotulutsira mpweya yokha yawonongeka.
Chachitatu, zolephera zomwe zimachitika kawirikawiri pokweza njira zoyezera
Chojambulira cha screw pakugwira ntchito kwa utsi ndi mafuta pakagwa vuto ndi zifukwa zosiyanasiyana, zifukwa zosiyanasiyana zimafuna njira zosiyanasiyana kuti zithetsedwe.
1.vuto la kuwonongeka kwapakati pa mafuta
Kuwonongeka kwa pakati pa mafuta ndi chinthu chofala, kotero mu screw compressor muyenera kuyang'aniridwa musanayambe kugwiritsa ntchito zida, mukugwiritsa ntchito njirazi kuyenera kutsatira kwambiri njira zogwirira ntchito, mutagwiritsa ntchito zida zosamalira nthawi zonse. Ndapeza kuti pakati pa mafuta ndi wosweka komanso wobowoka, ziyenera kusinthidwa nthawi yomweyo kuti zitsimikizire kuti zida zikugwira ntchito bwino.
2. Mavuto panjira yobwerera mafuta
Mu ntchito ya zida, ngati mukukumana ndi vuto panjira yobwerera mafuta, muyenera kuyang'ana kutsika kwa kuthamanga kwa cholekanitsa, monga kutsika kwa kuthamanga popanda mavuto, muyenera kuyeretsa pakati pa cholekanitsa mafuta, ngati pakati pa cholekanitsa mafuta pasweka, chiyenera kusinthidwa nthawi yomweyo.
3. Vuto loletsa kuthamanga kwa magazi m'dongosolo ndi lotsika kwambiri
Kwa woyendetsa, ayenera kudziwa bwino kuthamanga kwa makina, pamene vuto likupezeka kuti limachepetsa katundu wa makina, kotero kuti kuthamanga kwa makina kufika pa kuthamanga kwa ntchito komwe kumayenera kuchitika.
4. vuto lochepa la kulephera kwa valavu yopanikizika
Pakugwira ntchito kwenikweni, ngati valavu yochepetsera kuthamanga yapezeka kuti si yogwira ntchito, ndiye kuti iyenera kusinthidwa, kenako igwire ntchito ikatha kusinthidwa.
5. Vuto lowonjezera mafuta ozizira kwambiri ku compressor
Mukawonjezera mafuta oziziritsa ku compressor, choyamba muyenera kumvetsetsa kufunika kwa mafuta oziziritsa omwe ayenera kuwonjezeredwa ku chipangizocho, kuwonjezera mafuta oziziritsa kuyenera kukhala udindo wa munthu, ndipo nthawi zambiri kuyenera kulamulidwa pansi pa galasi lowonera.
6. Ubwino wa mafuta ozizira
Kuti muwonjezere mafuta oziziritsa, mafuta oziziritsa ayenera kuwonjezeredwa motsatira zofunikira za zida zomwe zili pa mafuta oziziritsa, chifukwa zofunikira za zida zosiyanasiyana pa mafuta oziziritsa sizili zofanana. Mukawonjezera, nthawi yowonjezerera iyenera kulembedwa, ndipo mafuta oziziritsa akafika nthawi yake yogwira ntchito, ayenera kusinthidwa nthawi yake. Ubwino wa mafuta oziziritsa owonjezeredwawo uyenera kulamulidwa mosamala kuti mafuta oziziritsa osayenerera asawonjezeredwe.
Chachinayi, zolemba za mavuto ndi njira zothetsera mavuto
Mu ndondomeko yothetsera mavuto pali mfundo zingapo zomwe ziyenera kukumbukiridwa, apo ayi cholakwikacho sichingathe kuthetsedwa, komanso chingayambitse zotsatirapo zazikulu.
Ngati chitoliro chobwezera chikuwoneka kuti ndi vuto, chitoliro chobwezera chikhoza kutsukidwa ndikutsekedwa kapena kuwotchereranso. Mu ndondomekoyi, muyenera kusamala ndi izi: choyamba, muyenera kuonetsetsa kuti chitoliro chobwezera mafuta chili chosalala, osati chifukwa cha kuwotcherera kuti m'mimba mwake wamkati mwa chitolirocho chikhale chochepa; kachiwiri, malo oyika chitoliro chobwezera mafuta ayenera kukhala olondola, nthawi zambiri pakati pa core separator concave ndi mpata pakati pa mapeto a chitoliro chobwezera mafuta mu 3 ~ 4mm.
Ngati akuona kuti vuto ndi core yolekanitsa, core yatsopano yokha ndiyo ingasinthidwe. Mu ndondomekoyi, muyenera kusamala ndi izi: choyamba, kufufuza mosamala ngati core yatsopano yolekanitsa yawonongeka; chachiwiri, kuchita ntchito yoyera yoyeretsa pamwamba pa silinda yolekanitsa ndi chivundikiro chapamwamba; pomaliza, kukhazikitsa kuyenera kuwona ngati pali zinthu zachitsulo ndi zinthu zina zoyendetsera magetsi pa pepala lotsekera pamwamba pa core yolekanitsa, chifukwa mafuta ozizira amazungulira mofulumira kwambiri mkati mwa core yolekanitsa, ndipo magetsi ambiri osasunthika adzapangidwa pa core yolekanitsa.
Ngati akuona kuti ndi vuto la kuchuluka kwa mafuta olekanitsa, ayenera kutayidwa bwino. Yang'anani kuchuluka kwa mafuta olekanitsa m'njira yoyenera, choyamba, chipangizocho chiyenera kuyimitsidwa, ngati ngodya yopendekera ya chipangizocho ndi yayikulu kwambiri, chiwonetsero cha mita ya mafuta mu chipangizocho sichili cholondola; kachiwiri, nthawi yowunikira ndi yoyenera kusankha musanayendetse galimoto kapena mutatha theka la ola mutatseka.
Ngakhale kuti screw compressor ndi chitsanzo chodalirika kwambiri, sichifuna kukonza ndi kukonza. Muyenera kudziwa kuti chipangizo chilichonse "chimagwiritsidwa ntchito katatu, mfundo zisanu ndi ziwiri pakukonza", chifukwa chake, kaya mafuta otulutsa utsi kapena zolakwika zina, ziyenera kulimbitsa ntchito yokonza, cholakwikacho chidzachotsedwa mu bud.
