Pusher Uye Bidirectional

Kune iyo pusher kana bidirectional conveyor, tension yebhandi ichave yakakwirira kupfuura yakajairwa yakachinjika conveyor;saka, mashafts pamativi maviri anodiwa kuti atariswe semadhiraivha shafts uye akaiswa mukuverenga.Kazhinji, ingangoita 2.2 nguva yechiitiko chiitiko kuti uwane iyo yakazara bhandi kushushikana.

FORMULA: TWS = 2.2 TW = 2.2 TB X FA

TWS muchikamu ichi zvinoreva kukakavara kuverengerwa kwebidirectional kana pusher conveyor.

Turning Calculation

Kutendeuka-Kuverenga

Iko tension calculation TWS yeconveyor inotenderera ndeyekuverengera kuunganidzwa kwakaunganidzwa.Naizvozvo, makakatanwa ari muchikamu chega chega chekutakura achakanganisa kukosha kwekunetsekana kwakazara.Izvi zvinoreva kuti, kushushikana kwakazara kunounganidzwa kubva pakutanga kwechikamu chekutyaira munzira yekudzoka, munzira yekudzoka kune iyo idler chikamu, uye wozopfuura nepakati pechikamu chekutakura kune chikamu chekutyaira.

Nzvimbo yekugadzira mune iyi unit ndeye T0 iyo iri pasi pedhiraivha shaft.Kukosha kwe T0 kwakaenzana ne zero;tinoverenga chikamu chimwe nechimwe kubva kuT0.Semuenzaniso, chikamu chekutanga chakatwasuka munzira yekudzoka chinobva kuT0 kuenda kuT1, uye izvo zvinoreva kukakavara kwakaunganidzwa kweT1.

T2 ndiyo yakaunganidzwa tension yenzvimbo yekutendeuka munzira yekudzoka;mune rimwe izwi, ndiko kukakavara kwakaunganidzwa kweT0, T1 uye T2.Ndokumbira uenderane nemufananidzo uri pamusoro uye uone kuunganidzwa kwakaunganidzwa kwezvikamu zvekupedzisira.

FORMULA: TWS = ( T6 )

Kushushikana kwakazara kwechikamu chekutyaira munzira yekutakura.

TWS muchikamu ichi zvinoreva kuverengerwa kwemakakatanwa kwemutakuri wekutakura.

 

FORMULA: T0 = 0

T1 = WB + FBW X LR X WB

Tension yecatenary sag panzvimbo yekutyaira.

 

FORMULA: TN = ( Ca X TN-1 ) + ( Cb X FBW X RO ) X WB

Kushushikana kwechikamu chekutendeuka munzira yekudzoka.

Nekukosha kweCa uye Cb, ndapota tarisa kune Tafura 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

Kushushikana kwechikamu chakatwasuka munzira yekudzoka.

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 )

Kushushikana kwechikamu chakatwasuka munzira yekutakura.

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 )

Kushushikana kwechikamu chekutendeuka munzira yekutakura.

Nekukosha kweCa uye Cb, ndapota tarisa kune Tafura 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

Spiral-Conveyor

FORMULA: TWS = TB × FA

TWS muchikamu ichi zvinoreva tension calculation ye spiral conveyor.

FORMULA: TB = [ 2 × RO × M + ( L1 + L2 )] ( WP + 2WB ) × FBW + ( WP × H )

FORMULA: TA = BS × FS × FT

Ndokumbira utarise Tafura FT uye Tafura FS.

Muenzaniso Unoshanda

Kuenzanisa kweTA neTB, uye mamwe maverengero ane hukama akafanana nemamwe marudzi evatakuri.Pane zvimwe zvirambidzo uye mirau padhizaini uye kuvaka kweiyo spiral conveyor.Naizvozvo, tichishandisa HONGSBELT spiral kana kutenderedza mabhandi kune spiral conveyor system, tinokukurudzira kuti utaure nezve HONGSBELT Injiniya bhuku uye ubate nedhipatimendi redu rebasa rehunyanzvi kuti uwane rumwe ruzivo uye ruzivo.

 

Chikamu Tension

Unit-Tension

FORMULA: TB = [ ( WP + 2WB ) X FBW ] XL + ( WP XH )

Kana kutakura zvigadzirwa zvine hunhu hwekuunganidzira, iyo friction force Wf inowedzera panguva yekuunganidza kutakura inofanirwa kuverengerwa pakuverenga.

FORMULA: TB = [ ( WP + 2WB ) X FBW + Wf ] XL + ( WP XH )

FORMULA: Wf = WP X FBP X PP

Inobvumirwa Tension

Nekuda kwezvinhu zvakasiyana zvebhandi zvine simba rakasiyana rekusimba iro rinozokanganiswa nekusiyana kwekushisa.Nokudaro, kuverenga kweyuniti inobvumirwa tension TA inogona kushandiswa kusiyanisa nebhanhire rose rekumanikidza TW.Ichi chigumisiro chekuverenga chichakubatsira iwe kuita sarudzo yakarurama yekusarudza bhandi uye kuenderana nezvinodiwa zvemutakuri.Ndokumbira utarise Tafura FS uye Tafura Ts mune kuruboshwe menyu.

 

FORMULA: TA = BS X FS X FT

BS = Conveyor Belt Tensile Simba ( Kg / M )

FS uye FT Tarisa kune Tafura FS uye Tafura FT

Dhiraivha Shaft Torque Calculation - TS

FORMULA :

TS = TW ?BW ?R

Zvekuverengera kukosha pamusoro, ndapota enzanisa netafura iri pazasi yekusarudza yakanakisa drive shaft.Kana iyo torque yedhiraivha shaft ichiri yakasimba zvakanyanya, iyo diki sprocket inogona kushandiswa kudzikisa torque, uye zvakare kugadzirisa mutengo wekutanga we shaft uye kubereka.

Kushandisa sprocket diki kukwana dhiraivha shaft iyo ine dhayamita yakakura kuderedza torque, kana kushandisa hombe sprocket kukwana shaft yedhiraivha iyo ine dhayamita diki kuwedzera torque.
