Turning-Calculation

Ubalo loxinzelelo lwe-TWS yesidluliseli esijikayo kukubala uxinzelelo oluqokelelweyo. Ke ngoko, uxinezeleko kwicandelo ngalinye elithweleyo liya kuchaphazela ixabiso loxinzelelo lulonke. Oko kuthetha ukuba, ukunyanzeliswa okupheleleyo kuqokelelwe ukususela ekuqaleni kwecandelo lokuqhuba ngendlela yokubuyisela, kunye nendlela yokubuyela kwindawo ye-idler, kwaye emva koko udlule kwicandelo lokuthwala ukuya kwicandelo lokuqhuba.

Indawo yoyilo kule yunithi yi-T0 ephantsi kwe-drive shaft. Ixabiso lika T0 lilingana noziro; sibala icandelo ngalinye ukusuka kwi-T0. Umzekelo, icandelo lokuqala elithe ngqo kwindlela yokubuyisela lisuka ku-T0 ukuya kwi-T1, kwaye oko kuthetha ukuba uxinzelelo oluqokelelweyo lwe-T1.

I-T2 yintlupheko eqokelelweyo yendawo yokujika kwindlela yokubuya; kwelinye igama, luxinzelelo oluqokelelweyo lwe-T0, T1 kunye ne-T2. Nceda ngokomfanekiso ongasentla kwaye ucinge ngoxinzelelo oluqokelelweyo lwamacandelo okugqibela.

IFOMU: TWS = ( T6 )

Uxinzelelo olupheleleyo lwecandelo lokuqhuba kwindlela yokuthwala.

I-TWS kule yunithi ithetha ukubalwa koxinzelelo lwe-conveyor ejikayo.

T5 = ( Ca X T4 ) + ( Cb X FBW X RO ) X ( WB + WP )

 

I-Spiral Conveyor

Spiral-Conveyor

IFOMU: TWS = TB × FA

I-TWS kule yunithi ithetha ukubalwa koxinzelelo lwe-spiral conveyor.

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

IFOMU: TA = BS × FS × FT

Nceda ubhekisele kwiTheyibhile FT kunye neTheyibhile yeFS.

Umzekelo Oluncedo

Ukuthelekiswa kwe-TA kunye ne-TB, kunye nezinye izibalo ezinxulumene nazo ziyafana nezinye iintlobo zokuhambisa. Kukho izithintelo ezithile kunye nemimiselo yoyilo kunye nokwakhiwa kwe-spiral conveyor. Ke ngoko, ngelixa usebenzisa i-HONGSBELT spiral okanye ukuguqula amabhanti kwi-spiral conveyor system, sicebisa ukuba ubhekisele kwi-HONGSBELT Engineering manual kwaye uqhagamshelane nesebe lethu lenkonzo yobugcisa ngolwazi oluthe vetshe kunye neenkcukacha.

 

Uxinzelelo lweyunithi

Unit-Tension

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

Ukuba iimveliso eziphetheyo zinophawu lokufumba, amandla okukhuhlana i-Wf athe anyuka ngexesha lokupakishwa kokuhanjiswa kufuneka athathwe ngokubala.

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

IFOMU: Wf = WP X FBP X PP

Uxinzelelo oluvumelekileyo

Ngenxa yezinto ezahlukeneyo zebhanti zinamandla ahlukeneyo okuxinana okuya kuchaphazeleka ngokuhluka kweqondo lokushisa. Ngoko ke, ukubalwa kweyunithi ye-tension evumelekileyo ye-TA ingasetyenziselwa ukungafani nebhanti ye-tension ye-TW. Esi siphumo sokubala siya kukunceda wenze ukhetho olufanelekileyo lokukhetha ibhanti kwaye ufanise iimfuno zomhambisi. Nceda ubhekisele kwiTheyibhile FS kunye neTheyibhile Ts kwimenyu esekhohlo.
