Indlela yokuxazulula inkinga yento yokuthi uketshezi lwe-compressor lushaye isilinda ku- umlimi wezimboni uhlelo

1. Izimbangela zokuhluleka kwe-stroke emanzi

① Uma usebenzisa ukulawula okwenziwa ngesandla, i-valve ye-throttle ayilungiswanga kahle, ukuvuleka kukhulu kakhulu, noma i-valve yokuntanta ayivalwanga ngokuqinile;

②I-valve yokwandisa okushisayo iyehluleka, noma i-bulb ezwa izinga lokushisa ifakwe ngokungalungile, futhi othintana naye akalona iqiniso, okuholela ekuvulekeni okukhulu;

③Ikhoyili ye-evaporator iwugqinsi kakhulu futhi umthwalo mncane kakhulu;

④ Ukunqwabelana kwamafutha ngokweqile ohlelweni;

⑤Umthamo wokupholisa we-compressor mkhulu kakhulu, noma umthwalo wokushisa we-warehouse mncane;

⑥ Ukulungiswa okungalungile kokusebenza kwe-valve;

⑦Isiqandisi ohlelweni lwesiqandisi sigcwele isiqandisi esiningi kakhulu;

⑧I-valve ye-solenoid ye-liquid ayivaliwe ngokuqinile;

⑨Kumjikelezo wokuminyanisa wezigaba ezimbili, lapho ivalvu yokumunca yesiteji sokucindezela okuphansi ivalwa noma ivuleka ngokuzumayo (noma inani lamayunithi okusebenza liyancipha ngokuzumayo futhi liyanda), kanye naku-intercooler. Ikhoyili yenyoka ingena ngokuzumayo oketshezini, okungase kubangele kalula ukushaywa okumanzi kwe-compressor yesiteji somfutho ophezulu.

Ngamafuphi, kunezici eziningi ezibangela ukushaywa okumanzi kwe-compressor, futhi izizathu kufanele zitholakale futhi ziqedwe ngokuvumelana nesimo esithile.

2. Izinsimbi, amathuluzi nemishini esetshenziswa ukuthola ukwehluleka kokushaywa okumanzi kwe-compressor yesiqandisi

①Ithuluzi: igeji yokucindezela, i-multimeter, imitha yokubopha, i-thermometer, imitha ye-qi ephindwe kabili.

②Amathuluzi: ama-wrenches, amathuluzi okunweba amapayipi, ama-valve okugcwalisa, udlawu olucijile, amapulangwe, amathoshi, amathuluzi akhethekile.

③Izisetshenziswa: ibhodlela le-fluid elisebenzayo, ibhodlela le-nitrogen, iphampu ye-vacuum, isethi ephelele yokushisela igesi.

3. Indlela yokusebenza ejwayelekile yokuthola ukwehluleka kwe-stroke okumanzi kwe-compressor yesiqandisi

Njengoba uhlelo lwesiqandisi lwama-chillers ezimbonini luwuhlelo oluyinkimbinkimbi olwakhiwe ngama-condensers, ama-evaporator, ama-valve okwandisa, kanye nezinsiza eziningi zemishini ezihlotshaniswayo futhi ezithonya omunye nomunye, uma idivayisi yesiqandisi ihluleka, umuntu akufanele agxile kuphela kwezinye Izinga lendawo, kuyadingeka ukwenza ukuhlolwa okuphelele nokuhlaziya okuphelele kwalo lonke uhlelo. Ngamafuphi, indlela evamile yokuthola yilezi:

“Lalela okukodwa, ukuthinta okubili, ukubukeka okuthathu, ukuhlaziya okune” isethi yezindlela eziyisisekelo.

Ukubukeka okukodwa: bheka ingcindezi yokuncela nokucindezela kokukhipha kwe-compressor; bheka izinga lokupholisa legumbi lokupholisa; bheka isimo seqhwa se-evaporator; bheka isimo seqhwa se-valve yokwandisa ukushisa.

Ukulalela okwesibili: ukulalela umsindo we-compressor egijima, kufanele kube nokunyakaza okucacile kwe-valve kuphela. Uma kunomsindo othi “through-through”, umsindo wesando owuketshezi; lalela umsindo wefriji egeleza ku-valve yokwandisa; lalela umsindo wefeni elipholile; lalela umsindo we-valve ye-solenoid; lalela ukuthi kukhona yini ukudlidliza okusobala epayipini.

Ukuthinta okuthathu: thinta izinga lokushisa langaphambili nangemuva le-compressor; thinta izinga lokushisa le-compressor cylinder liner nekhanda le-cylinder; thinta izinga lokushisa lokudonsa kanye nokukhipha amapayipi. Ukuhlaziya okune: Sebenzisa amathiyori afanele wedivayisi yesiqandisi ukuze uhlaziye futhi wahlulele lesi simo, uthole imbangela yokwehluleka, futhi uyiqede ngendlela ehlosiwe. Ukwahlulelwa kokuhluleka kwesando se-liquid akusekelwe kuphela ku-frosting yepayipi yokudonsa, kodwa ikakhulukazi kusukela ekwehleni okubukhali ekushiseni kokukhipha. Ngalesi sikhathi, ukucindezela kwe-exhaust ngeke kushintshe kakhulu, kodwa isilinda, i-crankcase, ne-exhaust chamber konke kuyathinteka. Kubanda noma kube nesithwathwa. Esimeni sokushaqeka kwe-hydraulic, kungalimaza uhlelo lokugcoba, kwenze umsebenzi wephampu kawoyela ube mubi kakhulu, kunciphe kakhulu udonga lwesilinda, futhi kubhoboze ikhanda lesilinda ezimweni ezinzima.

4. Indlela yokuxazulula inkinga kanye nokubuyisela ukusebenza okujwayelekile kwesiqandisi se-compressor wet stroke fault

Ukubhekana nezingozi ze-liquid shock kufanele kwenziwe ngokushesha, futhi ezimweni ezimbi kakhulu, ukuphathwa kwezimoto eziphuthumayo kufanele kwenziwe. Uma ukushaywa okumanzi okuncane kwenzeka ku-compressor yesiteji esisodwa, i-valve yokumunca i-compressor kuphela okufanele ivalwe, i-valve yokukhipha uketshezi yesistimu yokuhwamuka kufanele ivalwe, noma uketshezi olusesitsheni kufanele luncishiswe. i-noodle. Futhi unake ukucindezela kwamafutha kanye nokushisa kokukhipha. Uma izinga lokushisa likhuphukela ku-50 ℃, zama ukuvula ivalvu yokumunca. Uma izinga lokushisa lokukhipha umoya liqhubeka nokukhuphuka, ungaqhubeka nokulivula, futhi uma izinga lokushisa lehla, livale futhi.

Ukuze “i-stroke emanzi” ye-compressor yezinyathelo ezimbili, indlela yokwelapha ye-low-pressure stroke emanzi ifana neye-compressor yesiteji esisodwa. Kodwa uma kunenani elikhulu le-ammonia eligijimela kusilinda, i-compressor ephezulu yokucindezela ingasetshenziswa ukudambisa futhi ikhiphe nge-intercooler. Ngaphambi kokupompa phansi, uketshezi oluku-intercooler kufanele lukhishelwe ebhakedeni lokudonsa, bese ukucindezela kufanele kuncishiswe. Ijakhethi yamanzi okupholisa isilinda namafutha kufanele kupholiswe ngaphambi kokunciphisa ukucindezela: khipha amanzi okupholisa kudivayisi noma uvule i-valve enkulu yamanzi.

Lapho izinga le-liquid le-intercooler liphezulu kakhulu, i-compressor ephezulu yokucindezela ibonisa “i-stroke emanzi”. Indlela yokwelapha kufanele iqale ivale i-valve yokumunca ye-compressor ephansi, bese ivala i-valve yokudonsa ye-high-pressure compressor kanye ne-valve yokuhlinzeka ngoketshezi ye-intercooler. Uma kunesidingo, khipha uketshezi lwe-ammonia ku-intercooler emgqonyeni wokukhipha. Uma i-compressor ephezulu yokucindezela iqhwa kakhulu, misa i-compressor ephansi. Indlela yokwelapha elandelayo iyafana neyesigaba esisodwa.
