Pusher Futhi Bidirectional

Kumduduzi noma umthumeli we-bidirectional, ukungezwani kwebhande kuzoba phezulu kune-conveyor evamile evundlile;ngakho-ke, ama-shafts emaphethelweni amabili ayadingeka ukuze athathwe njengama-drive shafts futhi afakwe ekubalweni.Sekukonke, cishe izikhathi ezi-2.2 zesici sokuhlangenwe nakho ukuze uthole ukungezwani kwebhande okuphelele.

IFOMU: TWS = 2.2 TW = 2.2 TB X FA

I-TWS kule yunithi isho ukubala okushubile kwesidlulisi se-bidirectional noma pusher.

Ukuguqula Ukubala

Ukuphenduka-Ukubala

Isibalo se-tension TWS yesidluliseli esiphendukayo ukubala ukushuba okuqoqiwe.Ngakho-ke, ukungezwani kuzo zonke izingxenye zokuphatha kuzothinta inani lokushuba okuphelele.Lokho kusho ukuthi, ukungezwani okuphelele kunqwabelana kusukela ekuqaleni kwesigaba sokushayela ngendlela yokubuyisela, endleleni ebuyela endaweni engenzi lutho, bese kudlulela esigabeni esithwalayo siye esigabeni sokushayela.

Iphuzu lokuklama kule yunithi yi-T0 engaphansi kwe-drive shaft.Inani lika-T0 lilingana noziro;sibala zonke izigaba kusuka ku-T0.Isibonelo, isigaba sokuqala esiqondile endleleni yokubuyisela sisuka ku-T0 siye ku-T1, futhi lokho kusho ukungezwani okuqoqiwe kwe-T1.

I-T2 ingcindezi enqwabelene yesimo sokujika endleleni yokubuya;kwelinye igama, ukungezwani okuqoqiwe kwe-T0, T1 kanye ne-T2.Sicela ngokwalo mfanekiso ongenhla futhi uthole ukungezwani okunqwabelene kwezigaba zakamuva.

IFOMU: TWS = ( T6 )

Ukushuba okuphelele kwesigaba sokushayela endleleni yokuthwala.

I-TWS kule yunithi isho ukubala kokuqina kwesidluliseli esiphendukayo.

 

IFOMU: T0 = 0

T1 = WB + FBW X LR X WB

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

Ukushuba kwesigaba sokuphenduka endleleni yokuthwala.

Ukuze uthole inani elingu-Ca ne-Cb, sicela ubhekisele kuThebula 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 )

 

I-Spiral Conveyor

I-Spiral-Conveyor

IFOMU: TWS = TB × FA

I-TWS kule yunithi isho ukubala kokuqina kwe-spiral conveyor.

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

IFOMU: TA = BS × FS × FT

Sicela ubhekisele kuThebula FT kanye neThebula FS.

Isibonelo Esisebenzayo

Ukuqhathaniswa kwe-TA ne-TB, nezinye izibalo ezihlobene nazo ziyefana nezinye izinhlobo zabathumeli.Kunemikhawulo ethile kanye nemithethonqubo mayelana nokuklama nokwakhiwa kwe-spiral conveyor.Ngakho-ke, ngenkathi usebenzisa i-HONGSBELT amabhande asontekile noma ajikisa amabhande ohlelweni lokuthutha oluvunguzayo, sincoma ukuthi ubheke imanuwali yobunjiniyela be-HONGSBELT futhi uxhumane nomnyango wethu wesevisi yezobuchwepheshe ukuze uthole imininingwane eyengeziwe nemininingwane.

 

I-Unit Tension

I-Unit Tension

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

Uma imikhiqizo ephethe inesici sokunqwabelana, amandla okungqubuzana i-Wf anyuka ngesikhathi sokunqwabelana kokuthutha kufanele asetshenziswe esibalweni.

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

IFOMU: Wf = WP X FBP X PP

I-Tension Evumelekile

Ngenxa yezinto ezihlukene zebhande linamandla ahlukene aqinile azothinteka ngokuhlukahluka kwezinga lokushisa.Ngakho-ke, ukubalwa kweyunithi ye-tension evumelekile ye-TA kungasetshenziswa ukuze kuqhathaniswe nengqikithi ye-TW yebhande.Lo mphumela wokubala uzokusiza ukuthi wenze ukukhetha okufanele kokukhetha ibhande futhi uhambisane nezidingo zomthumeli.Sicela ubhekisele kuThebula FS kanye neThebula Ts kumenyu engakwesokunxele.
