Izinto ezichaphazela ukusebenza kakuhle kokugaya ibhola

Ukusebenza kokugaya kwebhola yebhola kuchaphazeleka kwizinto ezininzi, phakathi kwazo ezona ziphambili: ifom yokunyakaza yebhola yensimbi kwi-cylinder, isantya sokujikeleza, ukongezwa kunye nobukhulu bebhola yensimbi, inqanaba lezinto eziphathekayo. , ukukhethwa komgca kunye nokusetyenziswa kwe-arhente yokugaya. Ezi zinto zinempembelelo ekusebenzeni kwebhola lebhola ukuya kwinqanaba elithile.

Ukuya kumlinganiselo othile, ukuma kokunyakaza kwendlela yokugaya kwi-cylinder kuchaphazela ukusebenza kakuhle kokugaya ibhola. Indawo yokusebenza yelitye lokusila yahlulwe ngokwezi ndidi zilandelayo:
(1) Kwindawo yentshukumo ejikelezileyo kunye newayo, ubungakanani bokuzaliswa kwi-cylinder buncinci okanye akukho nto, ukwenzela ukuba izinto zikwazi ukwenza intshukumo efanayo yetyhula okanye intshukumo yokuwa kwi-cylinder, kunye nempembelelo enokwenzeka yebhola yentsimbi kunye nentsimbi. ibhola liba likhulu, libangela ukunxiba phakathi kwebhola yentsimbi kunye ne-liner, ngokuqhubekayo ukwenza i-mill yebhola ingasebenzi kakuhle;
(2) Yilahla indawo yokuhamba, gcwalisa inani elifanelekileyo. Ngeli xesha, ibhola yensimbi inefuthe kwizinto eziphathekayo, okwenza ukusebenza kakuhle kwebhola lebhola kuphezulu;
(3) Kwindawo ejikeleze umbindi webhola lebhola, ukunyakaza kwesetyhula kwebhola yentsimbi okanye ukuxubana nokuwa nokuphosa intshukumo kwenza ukuba uluhlu lwentshukumo yebhola yentsimbi lube luqilima, kwaye ukunxitywa kunye nempembelelo yempembelelo encinci;
(4) Kwindawo engenanto, ibhola yensimbi ayishukumi, ukuba isixa sokuzaliswa sikhulu kakhulu, uluhlu lokuhamba kwebhola yensimbi luncinci okanye alushukumi, ngoko luya kubangela inkunkuma yemithombo, kulula ukwenza i-mill yebhola. ukusilela.
Inokubonwa kwi-(1) ukuba xa isixa sokuzaliswa sincinci kakhulu okanye singabikho, i-mill yebhola ilahlekelwa yilahleko enkulu, eyona nto ivela kwimpembelelo yebhola yensimbi kwizinto eziphathekayo. Ngoku ilitye lokusila jikelele lithe tye, ukuze kuncitshiswe ngokufanelekileyo ilahleko yebhola yokusila ukuba ingabikho nto, kukho ilitye lokusila elithe nkqo.
Kwisixhobo sokugaya ibhola yendabuko, i-cylinder yebhola yebhola iyajikeleza, ngelixa i-cylinder yezixhobo zokuxuba imile, eyona nto ixhomekeke kwisixhobo sokuxuba esijikelezayo sokuphazamisa kunye nokushukumisa ibhola yentsimbi kunye nezixhobo kwi-barrel. Ibhola kunye nezinto ezijikelezayo kwizixhobo eziphantsi kwesenzo sesixhobo sokuxuba ngokuthe nkqo, ukwenzela ukuba izinto eziphathekayo zisebenze kuphela kwibhola yensimbi de idilize. Ngoko ke ifaneleke kakhulu kwimisebenzi yokusila ecolekileyo kunye nokusebenza kakuhle kokusila.

I-02 Isantya Ipharamitha ebalulekileyo yokusebenza kwebhola yebhola yisantya, kwaye le parameter yokusebenza ichaphazela ngokuthe ngqo ukugaya ukugaya ibhola. Xa uqwalasela izinga lokujikeleza, izinga lokuzalisa kufuneka liqwalaselwe. Izinga lokuzaliswa lihambelana ngokufanelekileyo kunye nesantya sokujikeleza. Gcina ireyithi yokuzalisa ingatshintshi xa uxoxa ngereyithi yokujika apha. Kungakhathaliseki ukuba yintoni imeko yokunyakaza kwentlawulo yebhola, kuya kuba neyona ndlela ifanelekileyo yokujikeleza phantsi kwezinga elithile lokuzaliswa. Xa izinga lokuzaliswa ligxininisekile kwaye izinga lokujikeleza liphantsi, amandla afunyenwe yibhola yensimbi aphantsi, kwaye amandla empembelelo kwizinto eziphathekayo aphantsi, anokuthi abe ngaphantsi kwexabiso lomda wokutyumzwa kwe-ore kwaye kubangele impembelelo engasebenziyo kwi-ore. amaqhekeza, oko kukuthi, iinqununu ze-ore aziyi kuphulwa, ngoko ke ukugaya ukusebenza kwesantya esiphantsi kuphantsi. Ngokunyuka kwesantya, amandla empembelelo yebhola yentsimbi enefuthe kwizinto eziphathekayo ayanda, ngaloo ndlela enyusa izinga lokutyunyuzwa kwamasuntswana ore ore, kwaye emva koko kuphuculwe ukusebenza kakuhle kokugaya ibhola. Ukuba isantya siyaqhubeka sikhula, xa sisondele kwisantya esibalulekileyo, iimveliso zengqolowa erhabaxa akulula ukuba ziphulwe, oku kungenxa yokuba emva kokuba isantya siphezulu kakhulu, nangona impembelelo yebhola yentsimbi inokunyuswa, kodwa inani lemijikelo. yebhola yensimbi yehla kakhulu, inani leempembelelo zebhola zentsimbi ngexesha leyunithi liyancipha, kwaye izinga lokutyunyuzwa kwee-particle ore zehla.

03 Ukongezwa kunye nobukhulu beebhola zentsimbi
Ukuba ubungakanani beebhola zetsimbi ezongeziweyo azifanelekanga, ububanzi bebhola kunye nomlinganiselo awufanelekanga, ngoko kuya kubangela ukunciphisa ukusebenza kakuhle kokugaya. Ukugqoka kwebhola yebhola kwinkqubo yokusebenza kukhulu, kwaye inxalenye enkulu yesizathu kukuba ibhola yensimbi eyenziweyo ayilawulwa kakuhle, nto leyo ekhokelela ekuqokeleleni kwebhola yentsimbi kunye nesiganeko sokunamathela kwibhola, kwaye emva koko ivelise. ukunxiba okuthile kumatshini. Njengeyona ndlela ingundoqo yokugaya ibhola yebhola, kuyimfuneko ukulawula kuphela inani lebhola lensimbi elongezelelweyo kodwa kunye nomlinganiselo walo. Ukulungiswa kwendawo yokugaya kunokunyusa ukusebenza kakuhle kokugaya malunga ne-30%. Kwinkqubo yokugaya, ukuchithwa kwempembelelo kukhulu kwaye ukugqoka ukugaya kuncinci xa ububanzi bebhola bukhulu. Ububanzi bebhola buncinci, impembelelo yokugqoka incinci, isambatho sokugaya sikhulu. Xa ububanzi bebhola bukhulu kakhulu, inani lemithwalo kwi-cylinder liyancitshiswa, indawo yokugaya yomthwalo webhola incinci, kwaye ukunxiba komgca kunye nokusetyenziswa kwebhola kuya kwandiswa. Ukuba ububanzi bebhola buncinci kakhulu, umphumo wokunyusa wezinto eziphathekayo uyanda, kwaye umphumo wokugaya impembelelo uya kuba buthathaka.
Ukuze kuphuculwe ngakumbi ukusebenza kakuhle kokusila, abanye abantu babeka phambili indlela echanekileyo yokwenza ibhola:
(l) Uhlalutyo lwe-Sieve yeentsimbi ezikrwada ezithile uze uzibeke ngokwamaqela ngokobukhulu bamasuntswana;
(2) Ukumelana nokutyunyuzwa kwentsimbi ekrwada kuyacazululwa, kwaye eyona mida yebhola efunekayo liqela ngalinye lamasuntswana ore ibalwa ngebhola edayamitha ye-semi-theory;
(3) Ngokweempawu zokuqulunqa ubungakanani besuntswana lezinto eziza kuba phantsi, umgaqo wokutyumza oomatshini bezibalo usetyenziselwa ukukhokela ukubunjwa kwebhola, kwaye umlinganiselo weebhola zentsimbi ezahlukeneyo zenziwa kumgaqo wokufumana ubuninzi. ukutyumza amathuba;
4) Ibhola ibalwa ngesiseko sokubala kwebhola, kwaye iintlobo zeebhola ziyancitshiswa kwaye 2 ~ 3 iintlobo zongezwa.

04 Inqanaba lezinto eziphathekayo
Inqanaba lezinto eziphathekayo lichaphazela izinga lokuzaliswa, eliya kuchaphazela umphumo wokugaya ibhola. Ukuba umgangatho wezinto eziphathekayo uphezulu kakhulu, uya kubangela ukuvinjelwa kwamalahle kwibhola lebhola. Ngoko ke, ukubeka iliso okusebenzayo kwinqanaba lezinto eziphathekayo kubaluleke kakhulu. Ngexesha elifanayo, ukusetyenziswa kwamandla kwebhola lebhola kuhambelana nenqanaba lezinto eziphathekayo. Kwinkqubo ephakathi yokugcina i-pulverizing, ukusetyenziswa kwamandla ombane webhola kubalelwa malunga ne-70% yokusetyenziswa kwamandla kwenkqubo yokucoca kunye malunga ne-15% yokusetyenziswa kwamandla kwesityalo. Kukho izinto ezininzi ezichaphazela inkqubo ye-pulverization yokugcina ephakathi, kodwa phantsi kweempembelelo zezinto ezininzi, ukuhlolwa okusebenzayo kwinqanaba lezinto eziphathekayo kubaluleke kakhulu.

05 Khetha iliner
I-plate ye-lining ye-mill yebhola ayikwazi ukunciphisa kuphela umonakalo we-cylinder, kodwa iphinde idlulisele amandla kwindawo yokugaya. Enye yezinto ezichaphazela ukusebenza kakuhle kokugaya ibhola kuchongwa ngumsebenzi womsebenzi womgca. Ukusebenza, kuyaziwa ukuba ukuze kuncitshiswe umonakalo we-cylinder kunye nokuphucula ukusebenza kakuhle kokugaya, kuyimfuneko ukunciphisa ukutyibilika phakathi kwendawo yokusila kunye ne-liner, ngoko ke usetyenziso oluphambili kukutshintsha imilo yendawo yokusebenza ye-liner kunye nokwandisa i-liner. i-friction coefficient phakathi kwe-liner kunye ne-medium yokusila. I-manganese ephezulu yentsimbi yayisetyenziswa ngaphambili, kwaye ngoku kukho irabha yerabha, imagnethi, i-angular spiral liner, njalo njalo. Ezi bhodi ze-lining eziguqulwayo azikho ngaphezu kweebhodi zentsimbi ze-manganese eziphezulu ekusebenzeni, kodwa zinokwandisa ngokufanelekileyo ubomi benkonzo yebhola lebhola. Ukusebenza kakuhle kokugaya kungaphuculwa ngokufanelekileyo ngokuphucula imeko yokunyakaza, izinga lokuguqula, ukongeza kunye nobukhulu bebhola yensimbi, umgangatho wezinto eziphathekayo kunye nomgangatho wezinto zokugqoka zebhola.
