Umda wesicelo kunye neemfuno zobugcisa zeevalvu zesikhululo samandla ukulungisa umonakalo wesixhobo kwiZixhobo zoThutho lwevalvu (I)
Indlela yokuncamathelisa amazinyo. Okokuqala kufuneka kususwe izinyo elaphukileyo, kwaye kusetyenzwe kwi-dovetail groove kwingcambu yamazinyo, usebenzisa into efanayo ukusetyenzwa kwezinyo elitsha kwi-dovetailed, usebenzisana ne-dovetail groove yegiya, gcina i-0.1 ~ 0.2 mm yokukhutshwa, kwaye wenze umatshini omtsha izinyo, ube nesibonelelo esithile sokugqiba, emva kokuba ubambene ngokuqinileyo amazinyo amatsha kunye neendawo zokubeka, wenze itemplate yamazinyo egiya, kwaye emva koko ugqibezele amazinyo amatsha, De isampuli inxibelelene ngokufanayo namazinyo. Le ndlela ifanelekile kwigiya kunye nokusebenza kakubi kwe-welding.
Umzobo 7-9 ubonisa indlela yokulungisa amazinyo awonakeleyo kwigiya.
Umzobo 7-9 ubonisa indlela yokulungisa amazinyo awonakeleyo kwigiya
1. Indlela yokulungisa umonakalo wezinyo ngamnye wegiya
(1) Indlela yokuncamathelisa izinyo. Okokuqala kufuneka kususwe izinyo elaphukileyo, kwaye kusetyenzwe kwi-dovetail groove kwingcambu yamazinyo, usebenzisa into efanayo ukusetyenzwa kwezinyo elitsha kwi-dovetailed, usebenzisana ne-dovetail groove yegiya, gcina i-0.1 ~ 0.2 mm yokukhutshwa, kwaye wenze umatshini omtsha izinyo, ube nesibonelelo esithile sokugqiba, emva kokuba ubambene ngokuqinileyo amazinyo amatsha kunye neendawo zokubeka, wenze itemplate yamazinyo egiya, kwaye emva koko ugqibezele amazinyo amatsha, De isampuli inxibelelene ngokufanayo namazinyo. Le ndlela ifanelekile kwigiya kunye nokusebenza kakubi kwe-welding.
(2) Indlela ye-Welding yokufaka izinyo. Le ndlela ifanelekile kwi-gear kunye nokusebenza kakuhle kwe-welding, kwaye inkqubo yokulungiswa kwayo iyafana nendlela yokudibanisa amazinyo okufaka.
(3) Indlela yokujonga imfumba edibeneyo. Kwizinyo eliqhekekileyo lobhola, lifakwe kwimfumba enye okanye ngaphezulu, kunye nendlela yokujonga kwizinyo eliqhekekileyo elijonga izinyo elitsha,
2. Ukulungisa i-gear fracture
Kwisixhobo sokuhambisa i-valve, ukuba i-gear iyaphuka, kufuneka itshintshwe nge-spare part entsha. Ukuba akukho nxalenye entsha yokuphumla okwethutyana, inokulungiswa ngokwendlela eboniswe kuMzobo 7-10.
Ukulungiswa kwe-gear fracture (1) Ukuqhekeka kwesixhobo esaphukileyo sicutshungulwa kwi-groove, kwaye emva koko i-gear ephukileyo ifakwe kwi-gear yokubuyisela, kunye ne-spot welding fixed.
(2) i-clamping groove yepleyiti yokomeleza yenziwe kumacala amabini ekupheleni komphetho wegiya. I-diameter yangaphandle ye-groove kufuneka ibe yi-5mm encinci kunobubanzi besangqa sengcambu, kwaye i-diameter yangaphakathi incinci kune-diameter yangaphakathi ye-rim. Ubunzulu begroove buxhomekeke kubukhulu begiya, ngokubanzi phakathi kwe-3 kunye ne-6mm.
(3) Ubungakanani begroove buya kuba namandla, kwaye imoto iya kwenza amakhonkco amabini okuqinisa. Amakhonkco amabini okomeleza aya kuhlanjululwa kwaye agxininiswe kwi-clamping groove yobuso obubini besiphelo.
Umda wesicelo kunye neemfuno zobugcisa zeevalvu zesikhululo samandla (1) Lo mgangatho uchaza uxinzelelo kunye neqondo lobushushu leevalvu zesikhululo samandla kunye neemfuno jikelele zemathiriyeli, uyilo, ukuhlolwa, ukumakishwa, ukupakishwa, ukugcinwa, uthutho, amaxwebhu okuhanjiswa, njl., kunye inika isikhokelo kwiimfuno zokuodola. Izixhobo zevalve kufuneka zikhethwe ngokwemiqathango yokusetyenziswa kunye neemfuno zokuvelisa; Iibholiti, amantongomane kunye nezinye izinto zokuqinisa kufuneka zikhethwe ngokuhambelana nokusetyenziswa koxinzelelo kunye nobushushu. Xa ukhetha izinto zokuthwala iinxalenye zeqokobhe, ubushushu obuphezulu bokusebenza buya kucaciswa kwiSihlomelo C. Lo mgangatho ubonisa iimfuno eziphantsi okanye ezincinci zokuyila i-valve, kodwa akusiyo imfuneko yoyilo olupheleleyo.
