Ifeni ye-axial flow yezimayini engu-250kw, i-K40-8-NO26 Mine Fan, ithunyelwa emabhizinisini ezimayini eSifundazweni sase-Hunan, e-China.Sebenzisa amamotho angaqhumisi anamandla kagesi angu-380V.Isikhathi sokusebenza kwe-fan siyiminyaka eyi-15.
Ukusebenza kahle okuphezulu, umsindo ophansi, awekho ama-humps ejika lesici
Uchungechunge lwesizukulwane esisha K no-DK lwema abalandeli abonga amandla
1. Uhlolojikelele
Uchungechunge lwesizukulwane esisha se-K ne-DK abalandeli bokonga amandla bemayini baklanywe ngempumelelo ngokusekelwe kubalandeli bangempela bamayini abonga amandla. Ngokuthuthukiswa kobuchwepheshe kanye nokuthuthukiswa kwesakhiwo, ukusebenza kwabo kwathuthukiswa futhi nosayizi womshini wandiswa. Lolu chungechunge lwabalandeli lusebenza kahle kakhulu, umsindo ophansi, ububanzi bokusebenza obubanzi, kanye nemiphumela ebaluleke kakhulu yokonga amandla. Ukwengeza, indandatho yokugeleza eyenza ukuzinza ifakwe kusilinda sabalandeli esiyinhloko, isuse ama-humps ejika lesici, iqinisekise ukusebenza okuzinzile kwefeni ngaphansi kwanoma yiziphi izimo zokumelana.
Ukuze kwandiswe ububanzi bokusebenza kwalolu chungechunge lwabalandeli futhi kuhlangatshezwane nezidingo zezimayini ezihlukahlukene ezinkulu, eziphakathi, nezincane okungezona ezemayini, ukuze amanethiwekhi okungenisa umoya aphansi, aphakathi nendawo, aphakeme ukumelana namavolumu amakhulu, aphakathi nendawo, amancane omoya angakhetha bonke abalandeli abayinhloko, abalandeli abasizayo, kanye nabalandeli besiteshi sezigaba eziningi abasebenza endaweni esebenza kahle kakhulu, lolu chungechunge lwabalandeli luthatha izilinganiso ezimbili zehabhu kanye nezinhlobo ezimbili ze-single (0.40) kanye nezinhlobo ezimbili ze-single (0.40) kanye neyunithi ye-0.40 (0.40). counter-rotation), okuyi-K40, K45 kanye ne-DK40, i-DK45. Futhi i-K40 isebenzisa ama-motor angama-4, 6, kanye nama-pole-8 ngesivinini esithathu, i-K45 isebenzisa ama-motor angu-4 no-6-pole ngesivinini esibili, kanti i-DK40 ne-DK45 isebenzisa ama-motor angu-6 kanye no-8-pole ngesivinini ezimbili ngokulandelanayo.
Ngale ndlela, "ngokuhlanganisa" usayizi womshini ngamunye ngezilinganiso ezimbili zehabhu, izinhlobo ezimbili zesakhiwo, nesivinini ezintathu ngendlela ethile, lolu chungechunge lwabalandeli lunengqikithi ye-93 imininingwane.
Ibanga lokusebenza namapharamitha obuchwepheshe ayinhloko ochungechunge lwesizukulwane esisha se-K kanye nabalandeli bochungechunge lwezimayini ezonga amandla e-DK ngaphandle kwama-humps kuboniswa kuThebula 2 nakuThebula 3 ngokulandelanayo. Izisindo eziyinkomba ezisohlwini lwethebula zifaka isisindo senjini kanye ne-diffuser yawo wonke umshini.
Imidwebo yesakhiwo kanye namathebula osayizi abalandeli be-K40 kanye ne-K45 baboniswa kuMfanekiso 6 kanye neThebula 6 no-7 ngokulandelanayo.
Indlela yokumelela imodeli (isibonelo) yochungechunge lwesizukulwane esisha K no-DK abalandeli okonga amandla imi kanje: K 40– 4 №.15
Inombolo yemodeli yabalandeli bezimayini ngu-15,
(“I-DJK” imele ifeni yezimayini yohlobo lwe-twin-screw) (okungukuthi ububanzi besondo elisebenzayo D = 15dr;
Isilinganiso sehabhu d = 0.40 Inombolo yesigxobo semoto ngu-4, n = 1450 r/m
