Ukomelela coke nelaphu ukwanda amalungu

Amandla inyama Cox compensators Phantsi amandla coke kuthetha ukukwazi kwayo ukumelana imithwalo ezahlukeneyo etshabalalisayo (shoka kumcola) kuyo ufakwa leyo ngexesha izithuthi, yokuphatha, kwaye lusidla ezikweni ngexesha zinyibilike. Lo mhlaba ithathwa ukuba yeyona ibalulekileyo isalathisi umgangatho we coke. Ngaba awakhi izohlwayo coke eyomeleleyo yenza ukugcina permeability igesi eliphezulu besigxina kunye nemveliso ephakamileyo kwiziko kuqhuma. coke amandla ujongwa uphazamiseko ngumntu kwiisampuli ekucaca ukuba ifuthe kunye imithwalo esirhabaxa. Umlinganiselo amandla uyatshintsha yokugalela (ubukhulu bamagaqa) ye ubume of coke ngexesha ezikolweni kunye nokusetyenziswa amalungu ilaphu ukwanda. Eyona ndlela isetyenziswa ngokubanzi yokufumanisa amandla coke ngokwaphula ngendlela igubu olujikelezayo. Le ndlela sikuko yokuba coke ezithile ubukhulu isampulu elimlinganiselo ethile obekwe ngaphakathi igubu, nalapho esijikeleziswa ngesantya kwangaphambili ixesha kwangaphambili. Izigaqa coke entrained phezulu kuwa, yaye athululwe, ngaloo ndlela ukufumana iqhekeza igubu kunye imithwalo esirhabaxa bayazonakalisa ngazo shiyana ngokuxhomekeke amandla abo mechanical. Amandla iphawulwa inguqu ubungakanani pieces coke ngenxa uvavanyo. Xa ilizwe lethu liye indlela eqhelekileyo yokuqingqa amandla coke igubu olucetywayo eRashiya ngasekupheleni E.Sundgrenom kwinkulungwane yeshumi elinesithoba elide. isigubhu 2,000 mm ubukhulu kunye 800 mm ububanzi kukho kumphezulu zezindlu ngokohlobo efestileni kwizinti-25 mm ubukhulu kunye efanayo echazwe therebetween compensators. Igubu ulayishiwe ubunzima coke isampulu 410 kg angaqwengwa 25 mm. Igubu esijikeleziswa ukuba imizuzu eli-15 kwi-10 Rev / imiz. kwisiphumo Ukutshatyalaliswa iingceba coke ukuze bawe phakathi izikhewu phakathi kweentonga. Isalathisi amandla ubunzima coke eseleyo ngaphakathi igubu. Inkalo olongezelelweyo sisixa 10-0 mm imveliso iqhekeza podbarabannom. Amava Long-term lubonise ukuba ukusebenza okuqhelekileyo ezikweni kuqhuma kunokuba coke, enika abanye igubu ayikho kg ngaphantsi kwama-300. Iintlobo emihle 340-350 kg igubu isampulu. iindlela ezifanayo amalunga ukwanda uvavanyo ngelaphu esetyenziswa kumazwe amaninzi, kunjalo, ubukhulu igubu, ubunzima bebekwisampulu, inani revolutions ezahlukileyo. Oku kwabangela ukunqongophala ekuthelekisweni izalathi si zokunikwa coke namandla kunye nokusebenza kwi yamaZiko zabo udubulo. Ngoko ke, ngo-1963 Soviet Sundgren wachaza indlela indawo yayo yathathwa yi indlela ngamazwe yokumisela amandla coke kwi kwigubu omncinci ezivaliweyo 1000 mm ubude (GOST 8929-65). Phezu engaphakathi igubu 4 ofunwa kwizibiyeli 100 mm. Ukuvavanya isampuli intlawulo coke enkulu ka-60 mm isixa-150 kg, nto leyo yahlulwe 3 ngokobunzima-50 kg. Igubu icala elinye la malungu (50 kg) kwaye enze ukuba uphendule ngesantya-25 Rev / min imizuzu-4. Isampulu koko isuswe agcwayele yokugalela enemingxuma esibusazinge ububanzi 40 mm ne-10 mm. Lubonakala isivuno amandla coke iqhekeza 40 mm (bana M40), kunye yayo abradability - isivuno iqhekeza 10-0 mm (M10 component) xa ipesenti Ubunzima isampuli. Bavavanywa iisampuli ezimbini. Kwimeko kweziphumo ukungangqinelani ngokwemiqathango M40 kunye ngaphezulu kwe-3% ngokubhekiselele ngaphezulu kwe-1% M10 uvavanyo lwesithathu isampula. Isiphumo sokugqibela umiselwa-avareji yokalo emileyo. Ayanda M40 kunye M10 ngezantsi, ngokuqina coke. Kwiminyaka yakutshanje, ngexesha ezininzi mveliso coke amandla yovavanyo efanayo igubu (elincinane) (GOST 5953-72), ngelo xesha linye bebekhuphela baze ujikelezo, kodwa athathe uvavanyo coke ubungakanani okuziinkozo 25 mm. index Amandla coke hoxa yi-25 mm iqhekeza (M25) kunye abradability - M10. Ixabiso avareji kwezi zalathisi yamandla coke, kwi-South izityalo USSR 1985 azifani ngaphakathi kolundi zilandelayo: M25 - ukususela 70.7 ukuya 88,9%; M10 - ukususela 6.3 ukuya 11.3%, kunye mveliso weRashiya kunye Kazakhstan: M40 - ukususela 57,8 ukuya 75,1%; M25 - ukususela 83.7 ukuya 87,6% kunye M10 - ukususela 6.5 ukuya 10.0%. iindlela Kwakhona echazwe yokuqingqa amandla iliza ezikweni coke zisetyenziswa kunye nabanye. A engxakini ezi ndlela zovavanyo coke amandla kwi imeko abandayo lilele yokuba abakwazi ukuqikelela amandla ayo kwiqondo lobushushu eliphezulu apho coke itshiswe eziko udubulo. izama ukuseka indlela yokuqingqa uzinzo wobushushu le coke. coke amandla kuxhomekeke ngokuqinileyo kwisixa kunye nefom iintanda nezixhobo zalo. Intshabalalo kwenzeka ngokusebenzisa amaqhosha kwizaphuko, ibeka ntshikilelo yangaphakathi okuvela phakathi coking. Uphando iye yasekwa ukuba utshintsho kwi GhostScript ubukhulu bamagaqa i coke ayikho ngokomlinganiselo amandla ngokwaphulwa, coke yokuqala nakhandiweyo ngokukhawuleza, isixa fayini ukunyuka kakhulu kwaye unciphisa kabukhali elikhulu, ngoko kobuntu kusihla. ukukhula esilandelayo ezinjengokwaphuka kukhokelela ikakhulu coke lingonakali, ukususela kukutyunyuzwa yonke intwana kunzima. Oku ukuba ukuvavanya amandla coke of ngcono ubume ngesihlungulo, efunyenwe emva kokuba ukuqaliswa kwazo zonke iintanda kunye ntshikilelo lwangaphakathi. Ukususa i coke ezikweni ngokufutha ngokusebenzisa tuyere lubonakalise ukuba nokubunjwa kwayo lungqamana phantse kungawi nokhozo nokwakheka ngcono. Yinto eyaziwayo ukuba kwerhasi permeability yokwanda kwamalungu ilaphu ndiyayicombulula izinto sofele nto yaphando ukwanda ukufana lamaqhosha bayo. Ukuphucula ukufana kubungakanani coke ukuze ufumane luzizicuku ubungakanani elilelona ukuba amaziko udubulo (25-40 mm), ukuzama pre-ukuzinzisa nokubunjwa kwayo screen nezikhundla ukuba isixa esithile uxinezeleko ngomatshini, kulandele ekulinganisweni izohlwayo ngenxa. Oku kuya kunciphisa ukwehla ngaphezu lunamahlwili amhlophe coke ukwenza kwi izohlwayo ezikweni udubulo kwaye nokuphucula permeability zerhasi icala nemimandla yawo-lobushushu eliphezulu.
