Ivalve yokutywina umphezulu wokusila kunye nokuhlanganisa Umqheba weValve kunye nemilinganiselo yepeyinti yesandla

Ngaba indlela yokugqiba ukugqiba, inokwenza iinxalenye ukuba zifumane ukuchaneka komgangatho ophezulu, ukuchaneka kwejometri kunye nokugqiba umphezulu, kodwa ayikwazi ukuphucula indawo ehambelanayo phakathi kokuchaneka komphezulu. Isixhobo sokugaya kufuneka sihlangabezane nezi zimbini zilandelayo: ① kulula ukuyifaka amasuntswana abrasive ② inokugcina ukuchaneka kwejometri yesixhobo sokugaya ixesha elide. Ngoko ke, ukusetyenziswa ngokubanzi kwezinto ezithambileyo kune-workpiece ukwenza izixhobo zophando, ezisetyenziswa ngokuqhelekileyo isinyithi esimpunga. Kwinkqubo yokudibanisa i-valve, umzimba we-valve usetyenziswa ngokubanzi njengeendawo zokubhekisela, ngokuhambelana nomyalelo ochazwe kwinkqubo yokuhlanganisa, kwaye indlela iqhutywe. Ngaphambi kokuhlanganisana, kuyimfuneko ukujonga ukuba ngaba iinxalenye ziye zachithwa kwaye zahlanjululwa.
Ivalve yokutywina umphezulu wokusila
Okokuqala, ukugaya imigaqo esisiseko kunye nezixhobo
(I) Imigaqo-siseko esisiseko:
Ngaba indlela yokugqiba ukugqiba, inokwenza iinxalenye ukuba zifumane ukuchaneka komgangatho ophezulu, ukuchaneka kwejometri kunye nokugqiba umphezulu, kodwa ayikwazi ukuphucula indawo ehambelanayo phakathi kokuchaneka komphezulu.
Ukugaya, isixhobo kunye nomphezulu wokusebenza uhambelana kunye, i-abrasives yokuzalisa ephakathi, xa isixhobo ecaleni kwendawo edibeneyo, umthambo onzima phakathi kwamacandelo amabini e-abrasive grits surface sliding or rolling, inxalenye ye-abrasive ifakwe okanye i-sessile kwindawo yesixhobo, kwaye unqunyulwe ngumphezulu we-workpiece ngumaleko obhityileyo kakhulu wesinyithi, incopho yeconvex kwi-workpiece iqala ukugaya, ngokuthe ngcembe ifezekisa imfuneko efanelekileyo yomphezulu.
Ukuze wenze umphezulu wokugaya umfaniswano, umzila wokunyakaza ohambelanayo kwinqanaba ngalinye kwindawo yokusebenza ukuya kwisixhobo sokugaya kufuneka ufane ngokusemandleni, ngoko ulwalathiso lwentshukumo yesihlobo kufuneka lutshintshwe rhoqo.
Ukukhawuleza ukunyakaza kokugaya, kuphezulu ukusebenza kakuhle, kodwa ukuba kuphezulu kakhulu, kuya kubangela ukuba i-workpiece ishushu kwaye ichaphazele ukuchaneka kwejometri. Ngelo xesha, kufuneka sinikele ingqalelo ukuba singafaki uxinzelelo olukhulu phezu komhlaba, ngaphandle koko kuya kubangela ukushisa.
Ngenxa yokuba ukugaya kukusebenza kakuhle, isixa sokusika sincinci kakhulu, ngoko ke sinokuqinisekisa ukususa umkhondo wokucutshungulwa kwenkqubo yokugqibela, isiseko sokulungisa impazamo yejometri ye-workpiece, encinci isibonelelo sokugaya, ngcono.
(2) Izixhobo zokugaya
Isixhobo sokugaya kufuneka sihlangabezane nezi zimbini zilandelayo: ① kulula ukuyifaka amasuntswana abrasive ② inokugcina ukuchaneka kwejometri yesixhobo sokugaya ixesha elide. Ngoko ke, ukusetyenziswa ngokubanzi kwezinto ezithambileyo kune-workpiece ukwenza izixhobo zophando, ezisetyenziswa ngokuqhelekileyo isinyithi esingwevu.
I-Abrasive ngumxube wezinto eziphathekayo kunye ne-abrasive fluid. Izinto ezisetyenziswa ngokuqhelekileyo ziyi-corundum (i-alumina), i-silicon carbide, i-boron carbide, i-chromium oxide, i-iron oxide kunye ne-diamond powder, i-coarse abrasive xa isetyenziswa.
Ulwelo lokusila lusetyenziselwa ukulungisa i-abrasive, kwaye ludlala indima yokuthambisa, ukupholisa kunye ne-oxidation.
Eyesibini, ivalve yokutywina umphezulu wokusila
(a) ukusila ngesandla
Ukugaya ngesandla kulula, kodwa ukusebenza okuphantsi, umgangatho ombi, ufanelekile kumashishini amancinci kunye nokulungiswa.
1. Ukusila ngezandla kwindawo yokutywina yomzimba wevalvu
Ukusetyenziswa komngxuma wesikwere sesixhobo sokugaya esinediskhi esimilisekileyo sibekwe kwindawo yokutywina yevalvu yomzimba, kwaye emva koko umqheba omde onentloko yesikwere isetyenziselwa ukuqhuba ipleyiti yokusila intshukumo yokusila. Kukho umphathi wekholamu yegadi okanye ubangele ipleyiti yokuqhuba ubushushu kwipleyiti yokusila ukuthintela isixhobo sokusila ekuvuleni indawo yokutywina.
Ngaphambi kokugaya, isixhobo sokugaya kufuneka sihlanjululwe, sigqitywe ngoluhlu lwe-abrasive, kwaye isixhobo sokugaya kufuneka sifakwe kwindawo yokutywina, okokuqala jikela i-clockwise 180 ° kwaye emva koko i-90 ° i-clockwise, ngokuphindaphindiweyo, nikela ingqalelo kwiyunifomu kunye namandla afanelekileyo. xa ugaya, kwaye rhoqo wongeza i-abrasive.
2, ipleyiti yevalvu, idiskhi yevalvu kunye nezinye iindawo zokutywina umphezulu wokusila
Ukusebenzisa kwi-plate yokusila yokugaya ngesandla, okokuqala kwi-plate ehlanganiswe ngokulinganayo kunye nomgca we-ejenti yokugaya, i-workpiece ifakwe kwi-plate, kwelinye icala ukwenza ukujikeleza kunye nokwenza intshukumo yomgca okanye ukunyakaza kwe-8.
Umbala we-PAINT wesibambo sevalve kunye nevili lesandla uyahluka ngokomgangatho wokutywina.
