I-axial flow fan ye-250kw mine, i-K40-8-NO26 Mine Fan, ithunyelwa kumashishini emigodi kwiPhondo lase-Hunan, e-China.Sebenzisa ii-motor-proof-proof motors ezinamandla ombane angama-380V. Ubomi benkonzo yoyilo lwefeni yiminyaka eyi-15.
Ukusebenza okuphezulu, ingxolo ephantsi, akukho humps kwi-curve yeempawu
Isizukulwana esitsha se-K kunye nochungechunge lwe-DK lwemba abalandeli bonga amandla
1. Isishwankathelo
Isizukulwana esitsha se-K kunye ne-DK yochungechunge lwabalandeli bokugcina amandla emigodini bayilwe ngempumelelo ngokusekelwe kubalandeli bokugcina amandla omgodi. Ngokuphuculwa kobugcisa kunye nokulungiswa kwesakhiwo, ukusebenza kwabo kwandiswa kwaye nobukhulu bomatshini bandiswa. Olu chungechunge lwabalandeli lunokusebenza okuphezulu, ingxolo ephantsi, uluhlu olubanzi lokusebenza, kunye neziphumo ezibalulekileyo zokonga amandla. Ukongezelela, i-flow stabilizing ring device ifakwe kwi-cylinder fan cylinder, isusa i-humps kwi-curve yeempawu, iqinisekisa ukusebenza okuzinzile kwefeni phantsi kwazo naziphi na iimeko zokumelana.
Ukwandisa uluhlu lwentsebenzo yolu luhlu lwabalandeli kunye nokuhlangabezana neemfuno zemigodi eyahlukeneyo emikhulu, ephakathi, kunye nencinci engeyiyo yemigodi, ukwenzela ukuba uthungelwano lwe-ventilation kunye nenani eliphantsi, eliphakathi, eliphakamileyo kunye nelikhulu, eliphakathi, elincinci lomoya liyakwazi ukukhetha abalandeli abaphambili, abalandeli abancedisayo, kunye nabalandeli besikhululo esinezigaba ezininzi ezisebenza kwindawo ephezulu yokusebenza kakuhle, olu luhlu lwabalandeli luthatha iindidi ezimbini ze-hub kunye neentlobo ezimbini ze-0.45 kunye neyunithi ye-0.45 (0.45) counter-rotation), ezizezi K40, K45 kunye DK40, DK45. Kwaye i-K40 isebenzisa i-4, 6, kunye ne-8-pole motors kwizantya ezintathu, i-K45 isebenzisa i-4 kunye ne-6-pole motors kwizantya ezimbini, kwaye i-DK40 kunye ne-DK45 zisebenzisa ii-motor ezi-6 kunye ne-8-pole kwizantya ezimbini ngokulandelelana.
Ngale ndlela, "ngokudibanisa" ubungakanani bomatshini ngamnye kunye ne-hub ratios ezimbini, iintlobo ezimbini zesakhiwo, kunye nezantya ezintathu ngendlela ethile, olu chungechunge lwabalandeli lunemilinganiselo ye-93.
Uluhlu lwentsebenzo kunye neeparitha eziphambili zobugcisa zochungechunge lwesizukulwana esitsha se-K kunye nochungechunge lwe-DK lwemigodi yokugcina amandla abalandeli ngaphandle kwama-humps aboniswe kwiThebhile 2 kunye neThebhile 3 ngokulandelelanayo. Ubunzima bereferensi obudweliswe kwitheyibhile bubandakanya ubunzima benjini kunye ne-diffuser yawo wonke umatshini.
Imizobo yesakhiwo kunye neetafile zesayizi ze-K40 kunye ne-K45 abalandeli bechungechunge baboniswa kwi-Figure 6 kunye ne-Tables 6 kunye ne-7 ngokulandelanayo.
Indlela yokubonisa imodeli (umzekelo) yesizukulwana esitsha se-K kunye nochungechunge lwe-DK kwiifeni ezonga amandla zemigodi ngolu hlobo lulandelayo: K 40– 4 №.15
Inombolo yoMzekeli weMigodi yi-15,
("i-DJK" imele i-twin-screw fan ye-mining mining) (okt ububanzi bevili lokusebenza D = 15dr;
Hub ratio d = 0.40 Motor pole inani 4, n = 1450 r/m
