Ifeni yokusalungiswa eyenziwe kubhayela obaselwa ngamalahle GY4-73 fan yokuphekela kwezimboni ukumelana nokugqoka kanye nokushisa okuphezulu
I-fan yokusalungiswa eyenziwe kubhayela ebaselwa ngamalahle iyisisetshenziswa esibalulekile ohlelweni lukabhayela obaselwa ngamalahle. Umsebenzi wayo ukukhipha igesi ewuketshezi ekhiqizwa ukushiswa kukabhayela ngokusebenzisa ukumuncwa kwengcindezi engemihle, nokugcina indawo efanelekile yokucindezela okungalungile esithandweni somlilo ukuze kuqinisekiswe ukushiswa kukaphethiloli okuphelele nokusebenza kukabhoyela ozinzile.
I. Isimiso Sokusebenza Esiyinhloko
Ifeni esalungiswa esingeniswayo idala indawo yengcindezi engalungile endaweni yokungena yabalandeli ngamandla amaphakathi noma i-axial thrust ekhiqizwe i-impeller ezungezayo, idonsa igesi eshisayo yokushisa ephezulu isuka esithandweni idlule kuflue iye kufeni, bese iyikhipha ngomtshingo wokuphuma iye kushimula (noma izinto zokuvikela imvelo ezifana nemishini ye-denifur).
Ukucindezela okubi kwesithando somlilo kufanele kulawulwe ngokuqinile (ngokuvamile -20 kuya ku-50 Pa). Ukucindezela okungalungile ngokweqile kungadonsa umoya obandayo, kunciphise ukusebenza kahle kokushisa kwebhayela, kuyilapho ukucindezela okungalungile okwanele kungase kubangele ukuvutha komlilo, kubangele izingozi zokuphepha.
Izinhlobo zamafeni okusalungiswa e-boiler centrifugal:
1) Umlandeli obhalwe phansi owenzelwe njengohlobo olulodwa lokumisa. Usayizi uhla kusuka ku-No 8 kuye ku-29.5.
2) Uhlobo ngalunye lomlandeli lungenziwa ngokujikeleza kwesokunxele noma amafomu okujikeleza okulungile.
3) Indawo yokuphuma kwefeni iboniswa nge-engeli yokuphuma kwe-casing.
4) Izindlela zokushayela zifaka: B, C izinhlobo ze-C yeBelt Drayivu; D Uhlobo lweDrayivu yokuhlanganisa; E, izinhlobo ze-F zeBelt Drayivu.
5) Isibonelo segama lomkhiqizo eligcwele ngukulandelayo:
G4-73no.20roidight45 degrees
Y4-73no.20DREFT90 degrees
Lapho u-G no-y amele abalandeli be-boiler Supply kanye nabalandeli bohlaka bohlaka ngokulandelana.
Izici zesakhiwo sabalandeli abasalungiswa be-boiler: I-fan yokusalungiswa eyenziwe nge-boiler ekhishwa ngamalahle
I-Centrifugal Fan:
I-Casing: Kwenziwe ngeplate yensimbi, iqinile futhi ithembekile, itholakala ezinhlotsheni ezihlanganayo noma ezivulekile, nezinhlobo ezivulekile ze-semi-ovulekile zilula ukulungiswa. Abalandeli abangezansi kukaNombolo 14 babaluleke kakhulu, kuyilapho lezo ezingenhla kuka-14 zivulekile kakhulu.
I-Impeller:
Isigaba seDrayivu: Yakhiwa Shaft Main, Ukuthwala Izindlu, Ukugibela Izindlu, kanye ne-pulley (noma ukuhlangana).
I-Inlet: I-Welded ibe ngumomo we-conical, yakha isakhiwo esilinganiselwe sokuguqulwa, esiseceleni komlandeli, ngesigaba sesiphambano esigoqiwe eceleni kwesiqondisi se-axial, sivumela ukungena kwegesi ku-infleller.
Umnyango we-throttle: Kufakwe ngaphambili kwe-inlet, esetshenziselwa ukulungisa ivolumu ye-airflow lapho ijubane labalandeli (ingcindezi) lihlala lihlala lihlala njalo.
I-boiler eyengelwe ukulungisa iphutha labalandeli okusalungiswa kwe-fan yokusalungiswa eyenziwe ngamalahle
Ukugqokwa kwengxenye ye-Centrifugal fan drive kuyinkinga evamile yemishini, okuhlanganisa indawo yokufaka i-blower, ukugqokwa kwezindlu, kanye nokugqokwa kwesimo se-fan shaft. Kulezi ziphambeko ezingenhla zabalandeli be-centrifugal, izindlela zokulungisa zendabuko zihlanganisa i-buildup welding, isifutho esishisayo, ne-electroplating, kodwa ngayinye inezithiyo ezithile: izinga lokushisa eliphezulu elikhiqizwa ukushisela likhiqiza ukucindezeleka okushisayo okungenakuqedwa ngokuphelele, okubangela ukulimala kwezinto ezibonakalayo kalula, okuholela ekugobeni kwengxenye noma ukuphuka; ngenkathi i-electroplating inqunyelwe ukujiya kwe-coating,
Izindaba zokufakwa kubhayela okusalungiswa okwenziwe kubhoyela okusalungiswa kwefeni elikhiqizwe ngamalahle
1. Uphiko lonke lwe-centrifugal fan kufanele lubekwe ngqo esisekelweni futhi lubekwe kusetshenziswa ama-SHAIT abhangqwe athambekele.
2. Okwenzelwe abalandeli be-puntrifugal abahlangene, izindawo ezinemishini esisekelweni kufanele zivikelwe kahle futhi akufanele zibe nokugqwala noma ukulimala. Lapho ubeka isisekelo esisekelweni, kufanele kufakwe kusetshenziswa ama-SHAIT athambekele.
3
4. Ngaphambi kokugxuma amagobolondo okuthela, umugqa we-axis we-rotor kufanele uhambisane nomugqa we-axis, ngasikhathi sinye uguqule igebe phakathi kwempoqo enkulu kanye ne-waender Plate enomgodi wezobuchwepheshe.
I-5. Ngesikhathi somhlangano we-shaft main kanye namagobolondo, amasheke kufanele kwenziwe ngokuya ngemininingwane emibhalweni yobuchwepheshe bemishini. Ukuvunyelwa phakathi kwesembozo esithwala kanye negobolondo le-bearing kufanele kugcinwe ku-0.03 kuye ku-0.04 millimeters (kulinganiswe ububanzi obungaphandle kwegobolondo lokuthwala).
6. Lapho uhlanganisa i-fan casing, isikhundla sokudonswa kufanele sihambisane ngokususelwa ku-rotor axis Centerline, kanye nezikhala ze-axial ne-radial phakathi kwe-inlet ye-impeller kanye ne-casing inlet kufanele zilungiswe ebangeni elishiwo imibhalo ebuchwepheshe yemishini. Ngasikhathi sinye, hlola ukuthi ama-anchor bolts afakwe ngokuphephile. Uma imibhalo yobuchwepheshe bemishini ingacacisi amanani wegebe, igebe elijwayelekile le-axial kufanele libe ngu-1/12 we-impoller angaphandle, kanti igebe le-radial kufanele lisatshalaliswe ngokulinganayo, nenani lamamitha amancane angemuva, thatha inani elikhudlwana). Ngesikhathi sokulungiswa, lwela ukunciphisa amanani wegebe ukuthuthukisa ukusebenza kahle kwabalandeli. Lapho uvumelanisa abalandeli, ukuphakamiseka phakathi kwe-fan shaft kanye ne-motor shaft akufanele kudlule amamitha ayi-0.05 radimely futhi akufanele kudlule u-0.2 / 1000 ekuthambekeni. Kwabathandi be-centrifugal nge-rolling bearings, ukuphathwa kabi kwezimbobo ezithwala amafreyimu womabili kunganqunywa ngemuva kokuthi i-rotor ifakiwe, ngokususelwa lapho ukujikeleza kubushelelezi.
UZibo Hongcheng fan Co, Ltd. ubheka ukukhiqizwa kochungechunge olungaphezulu kuka-50 kanye nezincazelo ezingaphezu kuka-600 nabalandeli. Le mikhiqizo isetshenziswa kabanzi ezimbonini ezinjengezimayini, izimayini zamalahle, amasimu kawoyela, izitshalo zamakhemikhali, ama-kilns, ama-boilers, izindwangu kanye nezinto zokwakha. Ukukhiqizwa ngokwezifiso nokucubungula ngokuya ngemidwebo enikeziwe iyatholakala. Uyemukelwa ukuxhumana nathi ngokubambisana.
