11. Izidingo ezikhethekile ze-valve kufanele futhi zinqunywe: ubude besakhiwo, ukuphakama kwe-valve, ubukhulu, ukumelana nokugeleza, umthamo wokuphuma, izici zokugeleza, izinga lokuvikela, ukusebenza kobufakazi bokuqhuma kanye neminye imingcele;
12. Nquma indawo yokufaka i-valve nokuma.
Ukusebenza kwe-axial fan ye-tubular kuthintwa ukucaciswa kwe-radial
Indawo yegesi ethuthwa i-axial flow fan ye-tubular iyigesi eqhumayo futhi evuthayo efana ne-carbon monoxide, i-petroleum gas, i-chemical gas noma i-I gas equkethe impushana eyingozi. Uma ingxenye ye-rotor yalolu hlobo lwesiphephetha-moya yenziwe nge-carbon steel evamile, kulula ukuhlahlela ndawonye futhi kuholele ekushisweni kwegesi ngenxa yokushayisana kwezingxenye, noma ukungcola okunjengesihlabathi noma uthuli lwensimbi kufakwe ku-rotor, okuholela engozini embi. Ukuze ugweme lolu hlobo lwengozi, lapho ifeni iletha i-gas medium enezinga eliphansi lokuqhuma, ivolothi yefeni yenziwe nge-steel plate, futhi i-impeller yenziwe nge-aluminium. Kodwa lapho ifeni edlulisa izinga eliphezulu lokuqhuma kwegesi esetshenzisiwe yenziwe ngezinto ze-aluminium.
I-radial clearance ye-axial fan ye-tubular ibhekisela ekuphumeni phakathi kwe-blade nodonga lwangaphakathi lwe-casing, futhi imvume ye-axial ibhekisela ekuvunyelweni phakathi kwe-impeller cascade. Ubukhulu bezinhlobo ezimbili zokususwa bunomthelela ekusebenzeni kwefeni.
I-radial clearance ye-tubular axial flow fan inkulu kakhulu, futhi ukucindezela okungalungile kuphezulu, okubophezelekile kubangela umehluko omkhulu wengcindezi phakathi kwephuzu le-blade kanye nezinhlangothi ezimbili zokuvunyelwa kwe-casing. Umehluko wengcindezi yisona sizathu esiyinhloko sokuvuza komoya we-axial. Ukuvuza kuphindiselwa emuva nge-blade bese kukhishelwa emkhathini, kwenze “ukugeleza komoya okujikelezayo. Umsebenzi wale ngxenye yokugeleza komoya uyachithwa, ukuze ukusebenza kahle kwe-fan kuncishiswe.
I-rotor itshela ukujikeleza, eduze kwe-axial spiral front gas, ngoba umoya ngokwawo unesisindo nomswakama kanye nezinhlayiya zothuli eziqukethwe emoyeni, utshelwa ukuthi ujikeleze i-blade nxazonke, izinhlayiya zomoya ziminyene eduze kwe-casing, eduze nengaphakathi. udonga lokugeleza okuzungezayo okuya phambili, eduze kokuqondisa kwe-radial ukwandisa ukuminyana kokugeleza komoya kanye nengcindezi engemihle. Kulokhu, ukuphuma kwe-radial kukhulu kakhulu futhi kubuyela emuva ebhandeni lendandatho yokususa elizungeze i-casing ukuze kukhiqizwe inani elikhulu lomoya we-tubular ogeleza ohlangothini lwe-axial ubuyela emuva, othinta ukugeleza komoya okuvamile, ukuze umoya udle umsebenzi. ngeze, ngaleyo ndlela kunciphisa ukusebenza kahle.
Lapho uklama futhi ulungisa imikhiqizo, kuyadingeka ukuthi kugcinwe imvume ethile ye-axial phakathi kwama-cascade, ikakhulukazi ukuqinisekisa ukuthi ama-cascade alandelayo anomoya ofanayo futhi aqede ithonya phakathi komunye nomunye, ngaphandle kwalokho izimo zokusebenza ezifanele zizowohloka. Ukugeleza komoya okungalingani kungase kusebenze njengomthombo wokudlidliza, okubangela ukuba i-blade engemuva idlidlize. Ngokuphambene nalokho, imvume ye-axial inkulu kakhulu, izokwenza ubukhulu be-axial bube bude kakhulu. Ngakho-ke, ubukhulu be-axial clearance bunomthelela emsindweni, ukudlidliza kanye nosayizi we-axial we-fan.
Okungenhla kuyi-Xiaobian ukuze ulethe konke okuqukethwe kolwazi, ngithemba ukukusiza, futhi ngiyakwamukela ukuthi uqhubeke nokunaka lesi sizindalwazi, u-Xiaobian uzokuletha njalo ulwazi lomkhiqizo olufaneleka kakhulu ukuze uthole inkomba yakho.
