Ulwazi lokugcinwa kweevalve

Iivalvu ze-Taike, njengezinye iimveliso zoomatshini, zifuna ukulungiswa. Umsebenzi wokugcinwa kakuhle unokwandisa kakhulu ubomi benkonzo yevalve.

1. Ukugcinwa kunye nokugcinwa kwevalve yeTaike

Injongo yokugcina kunye nokugcinwa kukuthintela iivalve zeTaike ukuba zonakaliswe ngexesha lokugcinwa okanye ukunciphisa umgangatho. Enyanisweni, ukugcinwa okungafanelekanga sesinye sezizathu ezibalulekileyo zomonakalo we-valve ye-Taike.

Iivalve zokuthatha kufuneka zigcinwe ngocwangco. Iivalve ezincinci zinokufakwa kwishelufu, kwaye iivalve ezinkulu zinokubekwa ngokucocekileyo kumgangatho wendawo yokugcina impahla. Akufunekanga zifunjwe kwaye umphezulu wodibaniso lweflange akufanele uchukumise umhlaba ngokuthe ngqo. Oku akukona nje i-aesthetics, kodwa kubaluleke ngakumbi, ukukhusela i-valve engonakalisweni. Ngenxa yokugcinwa okanye ukuphathwa ngendlela engafanelekanga, isondo lesandla liphukile, i-valve stem igxiliwe, kwaye i-nut yokulungisa isondo lesandla kunye ne-valve stem ikhululekile kwaye ilahlekile, ezi lahleko ezingadingekile kufuneka zigwenywe.

Kwii-valve ze-Taike ezingayi kusetyenziswa ngexesha elifutshane, ukupakishwa kwe-asbestos kufuneka kukhutshwe ukuze kugwenywe ukubola kwe-electrochemical kunye nomonakalo kwisiqu se-Taike valves.

Indawo yokungenisa ivalve ye-Taike kunye nendawo yokuphuma kufuneka ivalwe ngephepha lewax okanye ngeplastiki ukuthintela ukungcola ukuba kungangeni kwaye kuchaphazele ivalve.

Iivalvu ezinokugqwala emoyeni kufuneka ziqatywe nge-oyile yokunqanda umhlwa kwaye zikhuselwe ukunqanda umhlwa.

Iivalvu zangaphandle kufuneka zogqunywe ngezinto ezingangenwa yimvula kunye nezinto ezingangenwa luthuli ezifana nelinoliyam okanye i-tarpaulin. Indawo yokugcina ivalve kufuneka igcinwe icocekile kwaye yomile.

2. Ukusetyenziswa kwevalve yokuthatha kunye nokugcinwa kwayo

Injongo yokugcinwa kukwandisa ubomi beevalve zeTaike kunye nokuqinisekisa ukuvulwa nokuvala okuthembekileyo.

Umsonto we-Taike stem uhlala ukhuhla kwi-stem nut kwaye kufuneka uqatywe nge-oyile eyomileyo etyheli, i-molybdenum disulfide okanye umgubo wegraphite wokuthambisa.

Kwiivalvu ze-Taike ezingavuli kwaye zivale rhoqo, jika ivili lesandla rhoqo ukongeza i-lubricant kwimisonto yesikhondo sevalve ukunqanda ukuxhuzula.

Kwiivalvu zeTaike zangaphandle, umkhono okhuselayo kufuneka wongezwe kwisiqu sevalve ukukhusela imvula, ikhephu, uthuli kunye nomhlwa. Ukuba ivalve ngoomatshini ikulungele ukuhamba, thambisa i-gearbox kwangexesha.

Ukuqinisekisa ukucoceka kweevalve zeTaike.

Hlala unamathela kwaye ugcine imfezeko yamalungu evalvu. Ukuba i-nut yokulungisa i-handwheel iyawa, kufuneka ixhotyiswe ngokupheleleyo kwaye ayikwazi ukusetyenziswa ngokufanelekileyo. Ngaphandle koko, amacala amane aphezulu e-valve stem aya kujikeleza, kwaye ukuthembeka okuhambelanayo kuya kulahleka ngokuthe ngcembe, kwaye kuya kusilela ukusebenza.

Musa ukusebenzisa i-valve ukuthwala ezinye izinto ezinzima, musa ukuma kwi-valve ye-Taike, njl.

Isiqu sevalve, ngakumbi indawo ephothiweyo, kufuneka yosulwe rhoqo, kwaye i-lubricant engcoliswe luthuli kufuneka itshintshwe kufakwe entsha. Ngenxa yokuba uthuli luqukethe izithunzi kunye ne-debris, kulula ukugqoka intambo kunye nomphezulu we-valve stem kwaye ichaphazela ubomi benkonzo yevalve.

Iivalvu ezisetyenziswayo kufuneka zigcinwe kube kanye ngekota, kanye ngesiqingatha sonyaka emva kokufakwa kwemveliso, kanye ngonyaka emva kweminyaka emibini yokuqalisa ukusebenza, kwaye minyaka le phambi kokuqala kobusika. Yenza umsebenzi wevalve bhetyebhetye kunye nokuvuthela kanye ngenyanga.

3. Ukugcinwa kokupakisha

Ukupakishwa kuhambelana ngokuthe ngqo nokuba itywina eliphambili lokuvuza kwevalve yeTaike kwenzeka xa ivalve ivulwa kwaye ivaliwe. Ukuba ukupakishwa kuyasilela kwaye kubangela ukuvuza, ivalve nayo iya kusilela. Ngokukodwa ivalve yombhobho we-urea inobushushu obuphezulu ngokwentelekiso, ngoko ke umhlwa unzima kakhulu. Isigcwalisi sithandwa ukuguga. Ukugcinwa okuphuculweyo kunokwandisa ubomi bokupakisha.

Xa i-valve ye-Taike ishiya umzi-mveliso, ngenxa yeqondo lokushisa kunye nezinye izinto, i-extravasation ingenzeka. Ngeli xesha, kuyimfuneko ukuqinisa amantongomane kumacala omabini e-gland yokupakisha ngexesha. Ngethuba nje kungabikho ukuvuza, i-extravasation iya kwenzeka kwakhona kwixesha elizayo Qinisa, musa ukuyiqinisa ngokukhawuleza, hleze ukupakisha kulahlekelwe ukuqina kwaye kulahlekelwe ukusebenza kwayo kokutywinwa.

Enye ipaki yevalve yeTaike ixhotyiswe ngegrisi yemolybdenum dioxide. Emva kweenyanga eziliqela zokusetyenziswa, igrisi ehambelanayo yokuthambisa kufuneka yongezwe ngexesha. Xa kufunyenwe ukuba ukupakishwa kufuneka kuncediswe, ukupakishwa okuhambelanayo kufuneka kufakwe ngexesha lokuqinisekisa ukusebenza kokutywinwa.

4. Ukugcinwa kwamalungu othumelo

Ngethuba lokuvula kunye nenkqubo yokuvala i-valve ye-Taike, igrisi yokuthambisa eyongeziweyo ekuqaleni iya kuqhubeka ilahleka, idibene nefuthe lobushushu kunye ne-corrosion, ioli yokuthambisa iya kuqhubeka yoma. Ngoko ke, inxalenye yokudluliselwa kwe-valve kufuneka ihlolwe rhoqo, kwaye kufuneka izaliswe ngexesha xa ifunyenwe, kwaye qaphela ukunyuka kokugqoka ngenxa yokungabikho kwe-lubricant, okubangelwa ukungaphumeleli okufana nokugqithiswa okungahambiyo okanye ukungaphumeleli kwe-jamming.

5. Ukugcinwa kwevalve ye-Taike ngexesha lokutofa igrisi

Inaliti yegrisi ye-taike isoloko ingayihoyi ingxaki yomthamo wenaliti yegrisi. Emva kokuba i-grease gun ifakwe i-refueled, umqhubi ukhetha indlela yokudibanisa i-valve ye-Taike kunye ne-injection yegrisi, aze enze umsebenzi wokujova igrisi. Kukho iimeko ezimbini: kwelinye icala, inani elincinci lenaliti yegrisi likhokelela kwinaliti yegrisi eyaneleyo, kwaye umphezulu wokutywina unxiba ngokukhawuleza ngenxa yokunqongophala kwesithambiso. Kwelinye icala, inaliti yamafutha amaninzi ibangela inkcitho. Isizathu kukuba amandla okutywinwa kweevalve ezahlukeneyo ze-Taike azibalwa ngokuchanekileyo ngokodidi lwe-valve ye-Taike. Umthamo wokutywina unokubalwa ngokusekelwe kubukhulu kunye nodidi lwevalve ye-Taike, kwaye emva koko inani elifanelekileyo legrisi lingatofwa.

Iivalvu zeTaike zihlala zingayihoyi imiba yoxinzelelo xa utofa igrisi. Ngexesha lokutofa kwamafutha, uxinzelelo lwenaliti yamafutha lutshintsha rhoqo kwiincopho kunye neentlambo. Ukuba uxinzelelo lusezantsi kakhulu, itywina liya kuvuza okanye lingaphumeleli, uxinzelelo luya kuba phezulu kakhulu, izibuko lokutofa igrisi liya kuvaleka, kwaye amafutha angaphakathi aya kutywinwa okanye umsesane wokutywina uya kutshixwa ngebhola yevalve kunye nepleyiti yevalvu. . Ngokuqhelekileyo, xa uxinzelelo lwenaliti yegrisi lusezantsi kakhulu, igrisi etofwayo ikholisa ukuqukuqela ukuya kumazantsi omgodi wevalvu, oqhele ukwenzeka kwiivalvu zesango ezincinci. Ukuba uxinzelelo lwenaliti yegrisi luphezulu kakhulu, kwelinye icala, jonga umbhobho wegrisi. Ukuba umngxuma wegrisi uvalekile, yibuyisele endaweni yawo. Kwelinye icala, igrisi iyaqina. Sebenzisa ulwelo lokucoca ukuthambisa ngokuphindaphindiweyo igrisi yokutywina engaphumelelanga kwaye utofe igrisi entsha ukuyibuyisela. Ukongeza, uhlobo lwetywina kunye nezinto zokutywina nazo zichaphazela uxinzelelo lwenaliti yegrisi. Iindlela zokutywina ezahlukeneyo zineexinzelelo ezahlukeneyo zokutofa igrisi. Ngokubanzi, uxinzelelo lwenaliti yegrisi kwiitywina eziqinileyo luphezulu kunolo lwezitywina ezithambileyo.

Xa i-valve ye-Taike ifakwe igrisi, nikela ingqalelo kwingxaki yendawo yokutshintsha i-valve ye-Taike. Iivalvu zebhola yeTaike zihlala kwindawo evulekileyo ngexesha lolondolozo. Kwiimeko ezikhethekileyo, zinokuvalwa ukugcinwa. Ezinye iivalve zeTaike azinakuphathwa njengeendawo ezivulekileyo. Ivalve yesango le-Taike kufuneka ivalwe ngexesha lolondolozo ukuze kuqinisekiswe ukuba igrisi izalise igroove yokutywina ecaleni kweringi yokutywina. Ukuba ivuliwe, igrisi yokutywina iya kungena ngqo kwindlela yokuhamba okanye i-valve cavity, ibangele inkunkuma.

Ivalve yeTaikeTaike ihlala ingayihoyi impembelelo yenaliti yegrisi xa utofa igrisi. Ngexesha lomsebenzi wokutofa igrisi, uxinzelelo, umthamo wenaliti yegrisi, kunye nendawo yokutshintsha zonke ziqhelekile. Nangona kunjalo, ukwenzela ukuba kuqinisekiswe umphumo we-valve grease injection, ngamanye amaxesha kuyimfuneko ukuvula okanye ukuvala i-valve ukujonga umphumo we-lubrication ukuqinisekisa ukuba umphezulu webhola le-valve ye-Taike okanye isango lixutywe ngokulinganayo.

Xa utofa igrisi, nikela ingqalelo kwiingxaki ze-Taike valve body drainage kunye ne-screw plug yoxinzelelo loxinzelelo. Emva kovavanyo loxinzelelo lwevalve ye-Taike, irhasi kunye nokufuma kumngxunya wevalvu evaliweyo kuya kwanda kuxinzelelo ngenxa yokwanda kobushushu obuphakathi. Xa inaliti yegrisi, uxinzelelo kufuneka lukhutshwe kuqala ukuze kube lula ukusebenza kakuhle kwenaliti yegrisi. Emva kokuba igrisi ifakwe, umoya kunye nomswakama kwindawo evaliweyo zitshintshwa ngokupheleleyo. Ukunciphisa uxinzelelo lwevalvu ngexesha, nto leyo eqinisekisa ukhuseleko lwevalve. Emva kwesitofu segrisi, qiniseka ukuba uqinise idreyini kunye neeplagi zokukhulula uxinzelelo ukukhusela iingozi.

Xa utofa igrisi, jonga kwakhona ingxaki yokugungxulwa kwedayamitha yevalve ye-Taike kunye nesitulo seringi sokutywina. Umzekelo, i-valve yebhola ye-Taike, ukuba kukho ukuphazamiseka kwendawo evulekileyo, unokuhlengahlengisa indawo evulekileyo yomda ngaphakathi ukuze uqinisekise ukuba ububanzi buthe tye. Ukulungelelanisa umda akukwazi nje ukulandela indawo yokuvula okanye yokuvala, kodwa kufuneka kuthathelwe ingqalelo ngokupheleleyo. Ukuba indawo yokuvula i-flush kwaye indawo yokuvala ayikho, i-valve ayiyi kuvala ngokuqinileyo. Ngendlela efanayo, ukuba ulungelelwaniso lukhona, ukulungiswa kwendawo evulekileyo kufuneka kuqwalaselwe. Qinisekisa uhambo oluchanekileyo lwe-engile yevalvu.

Emva kokutofwa kwegrisi, indawo yokutofa igrisi kufuneka ivalwe. Kuphephe ukungena kokungcola, okanye i-oxidation ye-lipids kwindawo yokutofa igrisi, kwaye isigqubuthelo kufuneka sigqunywe ngegrisi echasene nomhlwa ukuphepha umhlwa. Ukuze usebenzise isicelo kwixesha elizayo.
