Ukugcinwa kwama-valve nsuku zonke
1. I-valve kufanele igcinwe ekamelweni elomile nelingena umoya, futhi zombili iziphetho zephaseji kufanele zivalwe.
2. Ama-valve agcinwe isikhathi eside kufanele ahlolwe njalo, ukungcola kufanele kususwe, futhi amafutha aphikisana nokugqwala kufanele asetshenziswe endaweni yokucubungula.
3. Ngemuva kokufakwa, ukuhlolwa okuvamile kufanele kwenziwe.Izinto zokuhlola eziyinhloko:
(1) Ukuguga kwendawo yokuvala.
(2) Ukuguga kwentambo ye-trapezoidal yesiqu ne-stem nut.
(3) Ukuthi ukupakisha kuphelelwe yisikhathi futhi akuvumelekile, uma konakalisiwe, kufanele kushintshwe ngesikhathi.
(4) Ngemva kwe-SINGLE UNIONIBHOLA VALVE X9201-TI-GREY ishintshiwe futhi yahlanganiswa, ukuhlolwa kokusebenza kokuvala kufanele kwenziwe.
Umsebenzi wokulungisa ngesikhathi sokujova i-valve grease
Umsebenzi wokunakekela i-valve ngaphambi kokushiselwa nangemva kokufakwa ekukhiqizeni udlala indima ebalulekile ekukhiqizeni nasekusebenzeni kwe-valve.Ukugcinwa okulungile, okuhlelekile futhi okuphumelelayo kuzovikela i-valve, yenze i-valve isebenze ngokujwayelekile futhi yandise impilo yesevisi ye-valve.ukuphila.Umsebenzi wokulungisa ama-valve ungase ubonakale ulula, kodwa akunjalo.Kuvame ukushaywa indiva izici zomsebenzi.
1. Lapho ujova amafutha kuvalvu, inani lomjovo wamafutha ngokuvamile alinakwa.Ngemuva kokuthi isibhamu somjovo wamafutha senziwe kabusha, opharetha ukhetha i-valve kanye nendlela yokuxhuma umjovo wamafutha, bese wenza umsebenzi womjovo wamafutha.Kunezimo ezimbili: ngakolunye uhlangothi, inani lomjovo wamafutha lincane futhi umjovo wamafutha akwanele, futhi indawo yokuvala uphawu igqoka ngokushesha ngenxa yokuntuleka kokugcoba.Ngakolunye uhlangothi, umjovo wamafutha omningi uholela emfucumfucwini.Isizathu siwukuthi asikho isibalo samandla ahlukene okuvala ama-valve ngokwesigaba sohlobo lwama-valve.Umthamo wokuvala ungabalwa ngokuya ngosayizi we-valve nohlobo, bese kuthi inani elifanelekile lamafutha lingajovwa.
2. Uma i-valve igcotshwa, inkinga yokucindezela ngokuvamile ayinakwa.Ngesikhathi sokusebenza komjovo wamafutha, ukucindezela komjovo wamafutha kushintsha njalo ngeziqongo nezigodi.Ingcindezi iphansi kakhulu, isivalo siyavuza noma siyehluleka, ingcindezi iphezulu kakhulu, indawo yokujova igrisi ivinjiwe, igrisi yangaphakathi yokuvala iqinisiwe, noma indandatho yokuvala ivalwe ngebhola le-valve nepuleti levalvu.Imvamisa, lapho umfutho womjovo wamafutha uphansi kakhulu, igrisi ejovwe ivame ukugelezela ngaphansi kwesikhala sevalvu, okuvamise ukwenzeka kumavalvu esango amancane.Uma umfutho womjovo wamafutha uphezulu kakhulu, ngakolunye uhlangothi, hlola umlomo womjovo wamafutha, bese uwushintsha uma imbobo yamafutha ivimbekile..Ngaphezu kwalokho, uhlobo lokuvala kanye nezinto zokubeka uphawu nazo zithinta ingcindezi yomjovo wamafutha.Amafomu ahlukene okuvala anezingcindezi ezihlukene zokujova amafutha.Ngokuvamile, ukucindezela komjovo kagrisi we-hard seal kufanele kube uphawu oluhle kakhulu oluthambile.
3. Uma ujova amafutha kuvalvu, naka inkinga yokuthi i-valve isendaweni yokushintsha.I-valve yebhola ngokuvamile isendaweni evulekile ngesikhathi sokulungiswa, futhi ezimweni ezikhethekile, ikhethwa ukuthi ivalwe ukuze igcinwe.Amanye ama-valve awakwazi ukuthathwa njengendawo evulekile.I-valve yesango kufanele ivalwe ngesikhathi sokulungiswa ukuze kuqinisekiswe ukuthi amafutha agcwalisa i-groove yokuvala eduze nendandatho yokuvala.Uma ivuliwe, igrisi yokuvala izowela ngqo kumzila wokugeleza noma i-valve cavity, okubangela ukungcola.
Okwesine, lapho i-valve igcotshwa, umphumela womjovo wamafutha ngokuvamile awunakwa.Ngesikhathi sokusebenza komjovo wamafutha, ingcindezi, umthamo womjovo wamafutha, nendawo yokushintsha konke kujwayelekile.Kodwa-ke, ukuze uqinisekise umphumela womjovo wamafutha we-valve, ngezinye izikhathi kuyadingeka ukuvula noma ukuvala i-valve, uhlole umphumela wokugcoba, futhi uqinisekise ukuthi ingaphezulu lebhola le-valve noma ipuleti lesango ligcotshwe ngokulinganayo.
5. Uma ujova amafutha, naka inkinga yokukhipha amanzi e-valve emzimbeni kanye nokukhulula ingcindezi yokuxhuma izintambo.Ngemuva kokuhlolwa kokucindezela i-valve, igesi namanzi emgodini we-valve we-valve cavity kuzothuthukiswa ngenxa yokwanda kwezinga lokushisa elizungezile.Lapho i-grease ijojowe, kuyadingeka ukukhipha indle futhi ukhulule ukucindezela, ukuze kube lula ukuqhubeka kahle komjovo wamafutha.Umoya kanye nomswakama endaweni evalekile kushintshwa ngokugcwele ngemva kokujova amafutha.Ukucindezela kwe-valve cavity kukhishwa ngesikhathi, okuqinisekisa nokuphepha kwe-valve.Ngemuva komjovo wamafutha, qiniseka ukuthi uqinisa ipayipi kanye namapulaki okusiza ukucindezela ukuvimbela izingozi.
6. Uma ujova igrisi, naka inkinga yamafutha afanayo.Ngesikhathi sokujova ugrisi ojwayelekile, imbobo yokukhipha amafutha eseduze kakhulu nembobo yomjovo wamafutha izokhipha amafutha kuqala, bese iye endaweni ephansi, futhi ekugcineni ifinyelele phezulu, futhi amafutha azokhishwa ngamunye ngamunye.Uma ingalandeli imithetho noma kungekho mafutha, kufakazela ukuthi kukhona ukuvinjelwa, futhi kufanele kuhlanzwe ngesikhathi.
7. Lapho ujova ugrisi, qaphela futhi ukuthi ububanzi bevalvu buhambisana nesihlalo sendandatho yokuvala.Isibonelo, nge-valve yebhola, uma kukhona ukuphazamiseka endaweni yokuvula, lungisa umkhawulo wendawo yokuvula ngaphakathi ukuze uqinisekise ukuthi ububanzi buqondile bese ukhiya.Ukulungisa umkhawulo akufanele nje uphishekele indawo yokuvula noma yokuvala, kodwa cabangela konke.Uma indawo yokuvula i-flush futhi indawo yokuvala ingekho, i-valve ngeke ivaleke ngokuqinile.Ngendlela efanayo, uma ukulungiswa kwendawo evaliwe kusendaweni, ukulungiswa okuhambisanayo kwendawo evulekile kufanele kucatshangelwe.Qinisekisa ukuthi i-valve ine-engeli efanele yokuhamba.
8. Ngemuva komjovo wamafutha, qiniseka ukuthi uyayivala imbobo yomjovo wamafutha.Ukuze ugweme ukungena kokungcola, noma i-oxidation yama-lipids embobeni yomjovo wamafutha, ikhava kufanele igcotshwe ngamafutha avimbela ukugqwala ukuze kugwenywe ukugqwala.ngokuhlinzwa okulandelayo.
9. Lapho ujova amafutha, ukucatshangelwa kufanele futhi kunikezwe ukwelashwa okuqondile kwezinkinga ezithile ekuthuthweni okulandelanayo kwemikhiqizo kawoyela esikhathini esizayo.Njengoba kunikezwe izimfanelo ezihlukene zedizili nophethiloli, amandla okugwaza nokuhlakazeka kukaphethiloli kufanele kubhekwe.Ekusebenzeni kwe-valve yesikhathi esizayo, lapho uhlangabezana nokusebenza kwesigaba sikaphethiloli, amafutha kufanele agcwaliswe ngesikhathi ukuvimbela ukuvela kokugqoka.
10. Uma ujova igrisi, ungawuzibi umjovo wamafutha esiqwini sevalvu.Kukhona ama-sliding bushings noma ama-packings ku-valve shaft, nayo edinga ukugcinwa igcotshiwe ukuze kuncishiswe ukumelana nokungqubuzana ngesikhathi sokusebenza.Uma ukugcoba kungenakuqinisekiswa, i-torque izokwandisa izingxenye zokugqoka ngesikhathi sokusebenza kukagesi, futhi ukushintshwa kuzoba nzima ngesikhathi sokusebenza ngesandla.
11. Amanye ama-valve ebhola amakwe ngemicibisholo.Uma kungekho umbhalo wesandla we-FIOW wesiNgisi, isiqondiso sesenzo sesihlalo sokuvala, hhayi njengereferensi yesiqondiso sokugeleza kwendawo ephakathi, futhi isiqondiso se-valve self-leakage siphambene.Ngokuvamile, ama-valve ebhola ahlezi kabili anokugeleza okuphindwe kabili.
12. Uma ugcina i-valve, futhi unake inkinga yokungena kwamanzi ekhanda likagesi kanye nendlela yokudlulisela.Ikakhulukazi imvula engena ngesikhathi sezimvula.Enye iwukugqwala indlela yokudlulisela noma umkhono wokudlulisela, kanti enye iwukuba yiqhwa ebusika.Lapho i-valve kagesi isetshenziswa, i-torque inkulu kakhulu, futhi ukulimala kwezingxenye zokudlulisela kuzokwenza ukuthi i-motor ingabi nomthwalo noma uhambo oluningi lokuvikela i-torque, futhi ukusebenza kukagesi akukwazi ukufezeka.Izingxenye zokudlulisela zonakele, futhi ukusebenza okwenziwa ngesandla akukwazi ukwenziwa.Ngemuva kwesenzo sokuvikela i-torque ephezulu, ukusebenza kwezandla nakho akukwazi ukushintsha, njengokusebenza okuphoqelekile, kuzolimaza izingxenye ze-alloy zangaphakathi.
Kafushane, ukugcinwa kwe-valve kuphathwa ngempela ngesimo sengqondo sesayensi, ukuze umsebenzi wokulungisa ama-valve ukwazi ukufeza umphumela wawo ofanele kanye nenjongo yokusetshenziswa.
