High-speed unomphela magnetic synchronous inverter motor

I-PMSM yokuqala yomhlaba enamandla amakhulu kanye nesivinini esikhulu isetshenziselwa le centrifugal chiller.Amandla ayo angaphezulu kuka-400 kW kanti ijubane layo lokuzungeza lingaphezulu kuka-18000 rpm.Ukusebenza kahle kwezimoto kungaphezu kuka-96% kanye no-97.5% kuya phezulu, kuphakeme kunezinga likazwelonke lebanga loku-1 ekusebenzeni kwezimoto.Ihlangene futhi ingasindi.I-PMSM enamandla angu-400kW inesisindo esifanayo ne-75kW AC induction motor.Ngokwamukela ubuchwepheshe bokupholisa i-spiral refrigerant spray ukupholisa i-stator ne-rotor, izinga lokushisa lemoto lingalawulwa cishe ku-40 ℃, kuqinisekiswe ukusebenza kahle.

I-high-speed motor direct-driven two-stage impellerIyunithi ithatha i-impeller enesivinini esikhulu eqhutshwa ngokuqondile enezigaba ezimbili.Amagiya asheshayo kanye nama-radial bearings angu-2 akhanseliwe, okuzokwenza ngcono ukusebenza kahle futhi kunciphise ukulahlekelwa komshini okungenani ngama-70%.Ngokushayela okuqondile kanye nesakhiwo esilula, i-compressor isebenza ngokuthembekile ngosayizi omncane.Ivolumu nesisindo se-compressor singama-40% kuphela womthamo ofanayo we-compressor evamile.Ngaphandle komsindo we-high-frequency yamagiya asheshayo, umsindo wokusebenza kwe-compressor uphansi kakhulu.Lokho kungu-8dBA ngaphansi kweyunithi evamile.
	Idizayini ye-pneumatic "wideband" yesimo sonke I-Impeller ne-diffuser ilungiselelwe ukusebenza kahle kakhulu kwe-compressor ngaphansi komthwalo we-25-100%.Uma kuqhathaniswa nomklamo ojwayelekile osuselwe ekusebenzeni komthwalo ogcwele, lo mklamo unganciphisa ukuncishiswa kokusebenza kahle kwe-compressor.I-inverter centrifugal chiller ibona ukulawulwa kwamandla ngesivinini esiguquguqukayo se-compressor kanye ne-engeli eguquguqukayo yokuvula ye-guide vane eqala ukwehla ngaphansi komthwalo ongu-50~60%.Kodwa-ke, i-Gree CVE series centrifugal chiller ingashintsha ngokuqondile isivinini se-compressor ngaphansi komthwalo ongu-25~100% ukuze kuncishiswe ukulahlekelwa okunyakazayo kwe-guide vane futhi kuthuthukise ukusebenza ngaphansi kwazo zonke izimo.
Kufakiwe i-sine-wave inverter Ngokwamukela ubuchwepheshe bokulawula okungenazinzwa, i-rotor yemoto ingabekwa ngaphandle kophenyo.Ngobuchwepheshe bokulungisa obulawulekayo be-PWM, i-inverter ingakhipha i-sine wave ebushelelezi ukuze kuthuthukiswe ukusebenza kahle kwezimoto.I-inverter ifakwe ngokuqondile kuyunithi, ilondoloza isikhala saphansi kumakhasimende.Ngaphezu kwalokho, zonke izintambo zokuxhumana zixhunywe efekthri ukuze kuthuthukiswe ukwethembeka kweyunithi.
	I-viscosity ephansi ye-vane diffuser Idizayini ehlukile ye-viscosity ephansi ye-vane diffuser kanye ne-airfoil guide vane ingashintsha igesi enesivinini esikhulu ibe yigesi yomfutho we-static ephezulu ngempumelelo ukuze ibone ukululama kwengcindezi.Ngaphansi komthwalo oyingxenye, ukuphambukisa kwe-vane kunciphisa ukulahleka kokubuyela emuva, kuthuthukisa ukusebenza komthwalo oyingxenye, futhi kwandise ububanzi bokusebenza beyunithi
Ubuchwepheshe bokucindezela bezinyathelo ezimbili Uma kuqhathaniswa nohlelo lwesiqandisi olunesiteji esisodwa, ukucindezela kwezigaba ezimbili kuthuthukisa ukusebenza kahle kokujikeleza ngo-5%～6%.Isivinini sokujikeleza kwe-Compressor siyehliswa ukuze i-compressor ithembeke kakhulu futhi iqine.
	I-High-effective hermetic impeller I-Compressor impeller iyi-ternary hermetic impeller, esebenza kahle futhi enokwethenjelwa kune-impeller engafihliwe.Isebenzisa i-airfoil 3-dimensional structure ukuze ikwazi ukuzivumelanisa nezimo.Ngokuhlaziywa kwezinto ezinomkhawulo, umshini wokuhlola ohlanganisa ama-3, ukuhlolwa kwebhalansi okuguquguqukayo, ukuhlolwa kwesivinini esingaphezu kwesivinini kanye nokuhlolwa kwangempela ngaphansi kwesimo sangempela sokusebenza, kwenziwa isiqiniseko sokuthi i-impeller ihlangabezana nemfuneko yokuklama futhi iyakwazi ukusebenza ngokuzinzile.I-Impeller kanye ne-basic shaft isebenzisa ukuxhumana okungenakhiye, okungagwema ukugxila kwengcindezi ngokwengxenye kanye ne-rotor's additive off-balance ebangelwa uxhumano oluyinhloko, ngaleyo ndlela ithuthukise ukuqina kokusebenza kwe-compressor.
Isishintshi sokushisa esisebenza kahle kakhulu Indawo yokushintshisana yokushisa idizayinelwe ngokusekelwe endleleni yokudlulisa ukushisa.Ilungiselelwe ukunciphisa ukulahleka kwengcindezi egelezayo kanye nokusetshenziswa kwamandla.I-sub-cooler ifakwe ngaphansi kwe-condenser.Ngezithiyo zokugeleza eziningi, idigri yokupholisa encane ingaba kufika ku-5℃.Ibhodi elihlukanisayo eliphakathi lamukela ipayipi elikhanyayo eliwugqinsi oluphindwe kabili kunepayipi elinentambo ukuze lihlanganiswe nebhodi elisekelayo, ngakho-ke, ipayipi lethusi ngeke lonakale ngaphansi komthelela wesiqandisi esinesivinini esikhulu.Idizayini yepuleti ye-tube eyi-3-V yamukelwa ukuze kuqinisekiswe umphumela wokuvala.
	Inkundla yokulawula ethuthukile Ukusebenza okuphezulu kwe-32-bit CPU kanye nephrosesa yesignali yedijithali ye-DSP kuyasetshenziswa.Ukunemba okuphezulu kweqoqo ledatha namandla okucubungula idatha kuqinisekisa isici sesikhathi sangempela kanye nokunemba kokulawula uhlelo.Kanye nesikrini sokuthinta se-LCD esimibalabala, umsebenzisi angabona kalula ukulawula okuzenzakalelayo nokulawula okwenziwa ngesandla ekususeni iphutha.Iphinde yamukele i-algorithm ehlakaniphile yokulawula inhlanganisela ye-Fuzzy-PID, ehlanganiswe nobuchwepheshe obukhaliphile, ubuchwepheshe be-fuzziness kanye ne-algorithm evamile yokulawula ye-PID, ukuze lolo hlelo lukwazi ukusheshisa ukusabela nokusebenza okuzinzile.
