Isahluko 1: Ama-Belt Conveyors kanye Nezingxenye zawo

Lesi sahluko sizoxoxa ngokuthi iyini i-conveyor yebhande kanye nezingxenye zalo.

 

Iyini i-Belt Conveyor?

I-belt conveyor iyisistimu eklanyelwe ukuthutha noma ukuhambisa izinto ezibonakalayo njengempahla, izimpahla, kanye nabantu ukusuka endaweni eyodwa ukuya kwenye.Ngokungafani nezinye izindlela zokudlulisa ezisebenzisa amaketango, ama-spirals, ama-hydraulics, njll., amabhande okuthutha azohambisa izinto kusetshenziswa ibhande.Kubandakanya iluphu yezinto eziguquguqukayo ezelulwe phakathi kwamarola acushwa yinjini kagesi.

Ngenxa yokuthi izinto ezithuthwayo ziyahlukahluka ngokwemvelo, okokusebenza kwebhande nakho kuyahlukahluka ngesistimu esetshenziswa kuyo. Ngokuvamile kuza njenge-polymer noma ibhande lenjoloba.

Izingxenye ze-Belt Conveyor

Isistimu yokuthutha ibhande elijwayelekile linepulley yekhanda, i-tail pulley, i-idler rollers, ibhande, nohlaka.

 

Ikhanda Pulley

I-head pulley iyona ehlanganiswe ne-actuator kanye ne-motor kagesi.I-pulley yekhanda ishayela isihambisi, ngokuvamile sisebenza njengamandla adonsayo kunokusunduza.Ikakhulukazi itholakala endaweni lapho umthumeli wempahla ethula khona umthwalo wayo, okwaziwa ngokuthi ukuphela kokukhipha isithuthi sebhande.Ngenxa yokuthi i-pulley yekhanda ishayela lonke uhlelo, ngokuvamile kuyadingeka ukwandisa ukudonsa kwayo ngebhande, ngaleyo ndlela izoba nejazi elibi elimboza indawo yayo yangaphandle.Leli jakhethi libizwa nge-legging.Ngezansi ukuthi noma iyiphi i-pulley enejazi izobukeka kanjani.

I-pulley yekhanda ngokuvamile inobubanzi obukhulu kunawo wonke ama-pulleys.Kwesinye isikhathi isistimu ingaba namapulley amaningi asebenza njengama-drive pulleys.I-pulley ekupheleni kokukhishwa idrayivui-conveyor idlerngokuvamile enobubanzi obukhulu kakhulu futhi izokhonjwa njenge-pulley yekhanda.

 

Buyela noma Umsila Pulley

Lokhu kutholakala ekugcineni kokulayisha kwesithumeli sebhande.Kwesinye isikhathi kuza nokuma kwephiko ukuhlanza ibhande ngokudedela impahla iwele eceleni kumalungu asekelayo.

Kusethaphu esilula sokuhambisa ibhande, i-pulley yomsila izofakwa kumagayidi ngokuvamile afakwe ukuvumela ukushuba kwebhande.Kwezinye izinhlelo zokudlulisa amabhande njengoba sizobona, ukuqina kwebhande kushiywa kwenye i-roller ebizwa ngokuthi i-take-up roller.

 

I-Idler Roller

Lawa ama-roller asetshenziswa ngobude bebhande ukusekela ibhande nomthwalo, ukuvimbela ukuhlehla, ukuqondisa ibhande, nokuhlanza i-carryback (into esele ibambelele ebhandeni).Ama-Idler roller angenza konke okungenhla noma okunye kwakho, kodwa kunoma iyiphi indawo, azohlala esebenza njengokusekela ibhande.

Kunama-rollers amaningi ahlukene emisebenzi ehlukene, njengoba ebalwe ngezansi:

 

I-Troughing Idlers

Amavila abhuqayo azoba namarola amavila amathathu asethwe ekucushweni okwenza "i-trough" yebhande.Zitholakala ohlangothini oluthwala umthwalo ku-conveyor yebhande.I-idler emaphakathi ilungisiwe, futhi okubili emaphethelweni akwazi ukulungiswa.Lokhu kwenzelwa ukuthi i-engeli nokujula kwe-trough kungahlukahluka.

Lawa mavila, uma eqashiwe, azonciphisa ukuchitheka kwamanzi futhi agcine indawo enqamulayo ehlala njalo ngobude besithumeli sebhande.Ukugcina indawo enqamulayo ehlala njalo kubalulekile ekuzinzeni.

 

 

I-Rubber Disk Idler

Le idler inamadiski erabha abekwe ebangeni elimisiwe eduze kwe-eksisi yerola.Emaphethelweni okwedlulele, ama-roller asondelene kakhulu ukuze akwazi ukusekela umkhawulo webhande, ojwayele ukudabula.Amadiski ahlukanisiwe azonqamula noma iyiphi into exhunyiwe yokuthwala/esele futhi anciphise ukwakhiwa okungaphansi kwebhande.Lesi yisizathu esivamile sokungahambi kahle (lapho ibhande lishintsha ohlangothini olulodwa lwesistimu futhi libangele ukungahambi kahle).

Kwesinye isikhathi amadiski ane-helical njengesikulufu futhi i-idler izobizwa ngokuthi i-rubber screw idler roller.Umsebenzi uzohlala unjalo.Isibonelo serola ye-screw idler siboniswa ngezansi.

I-screw idler nayo ingenziwa nge-rubber helix.Ama-screw idlers avame kakhulu lapho i-scrapper ekhumula i-carryback ingeke isebenze, ikakhulukazi kuma-conveyor amabhande eselula.

 

Umqeqeshi u-Idler

Amavila abaqeqeshi agcina ibhande ligijima liqondile.Isebenza ngokumelene nokukhohlisa.Ifinyelela lokhu nge-pivot emaphakathi enyakazisa irola emuva maphakathi uma ibhande likhukhuleka liye ohlangothini olulodwa.Iphinde ihlanganise namarola angumhlahlandlela amabili ukuze asebenze njengemihlahlandlela yebhande.

 

 

I-Conveyor Belt

Ekumiseni i-conveyor yebhande, ibhande mhlawumbe liyinkimbinkimbi kakhulu.Ukuqina namandla kubalulekile njengoba ibhande lithatha isijeziso esikhulu lapho lilayisha futhi lihambisa impahla.

Isidingo esikhulayo sobude obude bokudlulisa siye sagqugquzela ucwaningo ezintweni ezintsha, nakuba lokhu kuhlala kuza ngezindleko.Amabhande aqinile anamathela ngokuqinile emithethweni ehambisana nemvelo avame ukuza nezindleko zokusetha eziphezulu, ngezinye izikhathi izindleko azikwazi ukuthethelelwa.Ngakolunye uhlangothi, uma kuthathwa indlela yokonga, ibhande ngokuvamile lihluleka, okuholela ezindlekweni eziphezulu zokusebenza.Izindleko zebhande ngokuvamile kufanele zibe ngaphansi kuka-50% wesamba sezindleko zomthumeli webhande.

Ibhande lakhiwe izingxenye ezifana nalezi:

 

I-Conveyor Carcass
