Pusher Lan Bidirectional
Kanggo pusher utawa conveyor bidirectional, tension sabuk bakal luwih dhuwur tinimbang conveyor horisontal biasa;mulane, shafts ing loro ends perlu dianggep minangka drive shafts lan subsumed ing pitungan.Umumé, kira-kira 2,2 kaping faktor pengalaman kanggo entuk ketegangan sabuk total.
FORMULA: TWS = 2,2 TW = 2,2 TB X FA
TWS ing unit iki tegese pitungan tension saka conveyor bidirectional utawa pusher.
Nguripake Pitungan
TWS pitungan tension saka conveyor ngowahi kanggo ngetung tension akumulasi.Mulane, tension ing saben bagean mbeta bakal mengaruhi Nilai saka total tension.Tegese, tension total dikumpulake saka wiwitan bagean drive kanthi cara bali, ing dalan bali menyang bagean idler, lan banjur ngliwati bagean mbeta menyang bagean drive.
Titik desain ing unit iki yaiku T0 sing ana ing sangisore poros penggerak.Nilai T0 padha karo nol;kita ngetung saben bagean saka T0.Contone, bagean sakcara pisanan ing cara bali saka T0 kanggo T1, lan tegese akumulasi tension saka T1.
T2 minangka tension akumulasi saka posisi ngowahi ing cara bali;ing tembung liyane, iku akumulasi tension saka T0, T1 lan T2.Mangga miturut ilustrasi ing ndhuwur lan nemtokake tension akumulasi saka bagean pungkasan.
FORMULA: TWS = ( T6 )
Total tension saka bagean drive ing cara mbeta.
TWS ing unit iki tegese pitungan tension saka conveyor ngowahi.
FORMULA: T0 = 0
T1 = WB + FBW X LR X WB
Ketegangan catenary sag ing posisi drive.
FORMULA: TN = ( Ca X TN-1 ) + ( Cb X FBW X RO ) X WB
Tension saka bagean ngowahi ing cara bali.
Kanggo nilai Ca lan Cb, mangga deleng Tabel Fc.
T2 = ( Ca X T2-1 ) + ( Cb X FBW X RO ) X WB
TN = ( Ca X T1 ) + ( Cb X FBW X RO ) X WB
FORMULA: TN = TN-1 + FBW X LR X WB
Ketegangan bagean lurus ing cara bali.
T3 = T3-1 + FBW X LR X WB
T3 = T2 + FBW X LR X WB
FORMULA: TN = TN-1 + FBW X LP X ( WB + WP )
Ketegangan saka bagean lurus ing cara mbeta.
T4 = T4-1 + FBW X LP X ( WB + WP )
T4 = T3 + FBW X LP X ( WB + WP )
FORMULA: TN = ( Ca X TN-1 ) + ( Cb X FBW X RO ) X ( WB + WP )
Ketegangan saka bagean ngowahi ing cara mbeta.
Kanggo nilai Ca lan Cb, mangga deleng Tabel Fc.
T5 = ( Ca X T5-1 ) + ( Cb X FBW X RO ) X ( WB + WP )
T5 = ( Ca X T4 ) + ( Cb X FBW X RO ) X ( WB + WP )
Spiral Conveyor
FORMULA: TWS = TB × FA
TWS ing unit iki tegese pitungan tension conveyor spiral.
FORMULA: TB = [ 2 × RO × M + ( L1 + L2 ) ] ( WP + 2WB ) × FBW + ( WP × H )
FORMULA: TA = BS × FS × FT
Mangga deleng Tabel FT lan Tabel FS.
Tuladha Praktis
Perbandingan TA lan TB, lan petungan liyane sing gegandhengan padha karo jinis conveyor liyane.Ana watesan lan peraturan tartamtu babagan desain lan konstruksi conveyor spiral.Mulane, nalika nglamar HONGSBELT spiral utawa ngowahi sabuk kanggo sistem conveyor spiral, disaranake sampeyan waca manual HONGSBELT Engineering lan kontak karo departemen layanan technical kita kanggo informasi luwih lan rincian.
Unit Tension
FORMULA: TB = [ ( WP + 2WB ) X FBW ] XL + ( WP XH )
Yen produk sing nggawa kanthi karakteristik tumpukan, gaya gesekan Wf sing mundhak sajrone transportasi tumpukan kudu dilebokake ing pitungan.
FORMULA: TB = [ ( WP + 2WB ) X FBW + Wf ] XL + ( WP XH )
FORMULA: Wf = WP X FBP X PP
Tension sing diidini
Amarga bahan sabuk sing beda nduweni kekuatan tarik sing beda-beda sing bakal kena pengaruh variasi suhu.Mulane, pitungan saka unit allowable tension TA bisa digunakake kanggo kontras karo sabuk total tension TW.Asil pitungan iki bakal mbantu sampeyan milih pilihan sabuk sing tepat lan cocog karo panjaluk conveyor.Mangga deleng Tabel FS lan Tabel Ts ing menu kiwa.
FORMULA: TA = BS X FS X FT
BS = Kekuwatan Tarik Sabuk Konveyor ( Kg / M )

| FORMULA: | TS = TW ?BW ?R |
Kanggo nilai pitungan ing ndhuwur, mangga mbandhingake karo tabel ing ngisor iki kanggo milih poros drive paling apik.Yen torsi poros drive isih kuwat banget, sprocket cilik bisa digunakake kanggo nyuda torsi, lan uga ngirit biaya utama poros lan bantalan.
Nggunakake sprocket sing luwih cilik kanggo pas karo poros drive sing diametere luwih gedhe kanggo nyuda torsi, utawa nggunakake sprocket sing luwih gedhe kanggo pas karo poros drive sing diametere luwih cilik kanggo nambah torsi.
