Izixhobo zovavanyo kunye nokuseta

Oomatshini bokuvavanya amandla okuqhekeza banokujoliswa ngokuthe nkqo okanye ngokuthe tye. Oomatshini abathe tye badla ngokukhethwa kwiindibano ezinde zetyathanga, ngelixa oomatshini abathe tye banokufanelekela iisampuli ezimfutshane okanye indawo encinci yomgangatho. Uvavanyo lubandakanya ubude besampulu obuhlala buquka amakhonkco ama-5, ama-7, okanye ngaphezulu, kuxhomekeke kububanzi betyathanga/ubude bangaphakathi betyathanga kunye neenkcukacha ezisemgangathweni. Ityathanga libanjwe kwicala ngalinye ngamatyathanga akhethekileyo okanye imihlathi yokubamba eyenzelwe ukufaka uxinzelelo kuphela, kuthintelwe amaxesha okugoba. Ukulungelelaniswa okufanelekileyo kubalulekile ukuthintela ukungaphumeleli kwangaphambi kwexesha kwi-grips.

Iiparameter zoVavanyo oluPhambili

- Isantya Sokusetyenziswa Kwamandla: Umthwalo kufuneka wonyuswe ngokuthe chu nangokuqhubekayo. Imigangatho idla ngokuchaza izinga loxinzelelo (umz., i-10 MPa/s) okanye isantya esilawulwa ngumatshini ukuqinisekisa iziphumo eziphindaphindwayo. Ukulayisha ngokukhawuleza kakhulu kunokukhokelela ekufundweni kwamandla okungachanekanga, ngelixa isantya esicothayo kakhulu sinokuchaphazela ukujongwa kokuziphatha kwezinto.

- Umlinganiselo: Umatshini urekhoda amandla aphezulu (amandla okuqhekeza) kwaye rhoqo ubude ngexesha lokuqhekeka. Ubude bulinganiswa phakathi kwamanqaku athile kwikhonkco (ngesiqhelo amakhonkco amabini okanye amathathu ahlukeneyo) kwaye bubonisa ukuguquguquka—uphawu olubalulekileyo lokhuseleko, ngakumbi ekuphakamiseni amakhonkco.

- Izixhobo zokuBamba: Iigrips kufuneka zihambelane nobukhulu betsheyini kunye nejometri ukuze kuthintelwe ukutyibilika okanye imiphumo yokuqhekeka. Kwiitsheyini ezikumgangatho ophezulu ezifana ne-G80 kunye ne-G100, kuqwalaselwa ngononophelo ukuthintela umonakalo kumphezulu wekhonkco ngexesha lokubamba, nto leyo enokuba nefuthe kwiziphumo.

Isicelo kwiintlobo ezithile zeTyeya

- IiTyathanga zokuphakamisa ze-G80 kunye ne-G100: Ezi ziityathanga zentsimbi ezixineneyo kakhulu, ezinyangwa ngobushushu ukuze ziqine kwaye zingagugi. I-G80 inamandla okuqhekeza amancinci angama-800 MPa, kunye ne-G100 ye-1000 MPa. Uvavanyo luqinisekisa ukuba ibhetshi nganye iyahlangabezana nezi zincinci, kwaye ulwandiso ludla ngokuba yi-≥12% kwi-G80 kunye ne-≥10% kwi-G100.

- Iitsheyini Zokwemba Amalahle: Ezi tsheyini zisetyenziswa kwii-conveyor kunye neenkxaso zophahla ezisebenza ngamandla, zisebenza kwiindawo ezirhabaxa kakhulu nezinoxinzelelo olukhulu. Uvavanyo lwamandla okuqhekeza luqinisekisa ukuba ziyakwazi ukumelana namandla okulayisha aguqukayo kunye namandla okutshatyalaza phantsi komhlaba.

- Iintambo ze-Bucket Elevator: Ezi ntambo ziphatha izinto ezinkulu; uvavanyo luqinisekisa ukumelana nokudinwa kunye namandla phantsi komthwalo oqhubekayo, rhoqo kugxininiswa ngakumbi ekunwetshweni ukuze kuthintelwe ukungaphumeleli kokuqhekeka.

- Iintambo zokuLashing (iintambo zokubophelela): Ezisetyenziselwa ukubopha imithwalo, kufuneka zihlangabezane namanqanaba athile (umz., iBanga lesi-8, iBanga le-10). Uvavanyo lwamandla okuqhekeza luqinisekisa imida yomthwalo wokusebenza kunye nezinto zokhuseleko, ezidla ngokuba yi-4:1 okanye ngaphezulu.

Ukubaluleka koVavanyo oluchanekileyo

Idatha yamandla okuqhekeza ethembekileyo iqinisekisa ukuba amatsheyini asebenza ngokukhuselekileyo phantsi kwemida yawo yokusebenza elinganisiweyo. Isantya esingaguqukiyo, ukuxinana okungekho semgangathweni, okanye umlinganiselo ongalunganga kunokukhokelela ekudluleni okanye ekusileleni okungeyonyani, okubeka ukhuseleko esichengeni kwaye okukhokelela kuxanduva. Ukulinganiswa rhoqo koomatshini bokuvavanya kunye nokuthotyelwa kweenkqubo ezibhaliweyo kuyimfuneko kuvavanyo oluvunyiweyo.

Uvavanyo lokuqhekeza amandla luhlala luyindlela eqinisekileyo yokuqinisekisa ukuthembeka koomatshini beetyathanga ezijikelezileyo. Kubavelisi kunye nabasebenzisi beetyathanga zokuphakamisa ze-G80/G100, iityathanga zemigodi, iityathanga zelifti, kunye neetyathanga zokuqhawula, ukuthotyelwa ngokungqongqo kweenkqubo zovavanyo ezisemgangathweni kuqinisekisa ukuba iityathanga ziyahlangabezana nemigangatho yamandla kunye nokuguquguquka okufunekayo. Ukutyala imali kwizixhobo zovavanyo ezichanekileyo kunye nokusebenza okuqeqeshweyo akupheleli nje ekuzalisekiseni uxanduva lolawulo kodwa kukwagcina imigangatho yokhuseleko ephezulu kwimisebenzi yemizi-mveliso.

Ukwandiswa kwekhonkco lekhonkco ngexesha lovavanyo lokuqhekeka kwamandla yindlela ebalulekileyo yokulinganisa umgangatho walo, nto leyo ebonisa okungaphezulu kwamandla okugqibela. Isebenza njengesalathisi esibalulekileyo sokuguquguquka kwezinto, ukuhambelana kokwenziwa, kunye nokuthembeka kwesakhiwo ngokubanzi.

Iindlela zokulinganisa ubude

Ukwandiswa kulinganiswa njengokwanda okusisigxina kobude betsheyini emva kokuba iqhekekile, okubonakaliswa njengepesenti yobude bokuqala. Kukho iindlela ezimbini eziphambili zokulinganisa:

i) Uvavanyo Lokonakalisa Elabhoratri (Ngexesha Lokwenziwa Nokuqinisekiswa)

Le yindlela ephambili yokulawula umgangatho wokugqibela kunye nokuvunywa kohlobo.

Ubude betsheyini obumiselwe kwangaphambili (umz., iilinki ezi-5 okanye ezi-7) bufakelwa kumatshini wokuvavanya ukuxinana. I-laser displacement sensor okanye i-extensometer ilinganisa ngokuchanekileyo umgama phakathi kwamanqaku amabini aphawulweyo kwitsheyini njengoko amandla esetyenziswa ekutshabalaleni.

Ibamba ubude obupheleleyo (beplastiki) xa iqhekeza amandla, inika ixabiso eliqinisekileyo lokuqinisekiswa komgangatho. Oomatshini abaphambili benza igophe elipheleleyo lobude bamandla, elibonisa amanqanaba okuguquguquka kunye nokuguquguquka kweplastiki.

ii) Ukulinganisa ngaphakathi nangaphakathi kwenkqubo (Ukubeka iliso nokulungisa)

Ezi ndlela zingatshabalalisiyo zijonga ubude bexesha lokusetyenziswa ukuze ziqikelele ukungaphumeleli.

Indlela yokuHlalutya uMfanekiso: Umfanekiso weekhonkco zetyathanga uyahlalutywa. Inkqubo ibala iiphitshi ezahlukeneyo (ubude) beekhonkco zangaphakathi nezangaphandle. Ukuguguleka kunye nobude kwenzeka ikakhulu kwiikhonkco zangaphakathi; ubude bubalwa ngokuthelekisa iphitshi yangaphakathi eyonyukileyo kunye nephitshi yangaphandle ezinzileyo.

Indlela Yokubala I-Signal Pulse: Isetyenziselwa iitsheyini ezihamba rhoqo. Ii-sensors ezimbini zibekwe umgama omiselweyo kude. I-marker kwikhonkco elinye idlula i-sensor yokuqala, iqalise i-counter ebala ii-pulses ukusuka kwii-markers kwiikhonkco ezilandelayo de i-marker yokuqala idlule i-sensor yesibini. Ukubala okwandisiweyo kubonisa ukuba i-chain inwebile.

KwiiTsheyini zokuphakamisa ezikumgangatho ophezulu (umz., G80, G100), ukunwebeka kwesango lomgangatho ongqongqo:

Iintambo ze-G80: Ubuncinane bobude ngexesha lokuphumla buqhele ukuba yi-15%.

Iintambo ze-G100: Ubuncinane bobude ngexesha lokuqhekeka buqhele ukuba yi-12%.

Ezi zincinci ziphezulu ziqinisekisa ukuqina okugqwesileyo kunye nokufunxwa kwamandla. Itsheyini ehlangabezana namandla okuqhekeka kodwa enobude obuphantsi iyaphuka kwaye isengozini yokusilela ngequbuliso, ukusilela ngequbuliso phantsi kwemithwalo yoxinzelelo—ingozi enkulu yokhuseleko.

Kwizicelo ezinje ngemigodi yamalahle okanye ii-bucket lifti, uhlalutyo lwe-chain links elongation luza kuchongwa:

Uluhlu olujoliswe kulo: Ukwandiswa okwamkelekileyo kudla ngokuba phakathi kwe-10% kunye ne-15%.

Ukwandiswa okuphantsi kakhulu (<10%) kubonisa iingxaki zezinto okanye unyango lobushushu, nto leyo ekhokelela ekuqhekekeni okubuthathaka. Uphando olwenziwe kwiitsheyini zemigodi lubonisa ukuba ukwandiswa okungalunganga kudla ngokunxulumana neepateni zokuqhekeka ezingafunekiyo kwindawo yokuwelda, indawo ebuthathaka kakhulu.

Ukuphakama okuphezulu kakhulu (>18-20%) kunokubonisa ukuba izinto ezithambileyo okanye ukuqina okunganelanga, okuphazamisa ukuxhathisa ukuguguleka kunye nokuvumela ikhonkco ukuba litshintshe ngokusisigxina ("likhule") kakhulu phantsi komthwalo oqhelekileyo, okubangela iingxaki zokusebenza ezifana nokungasebenzi kakuhle kwee-sprockets.
