Txoj Kev Ua Tau Ntawm Txoj Kev Castings

Txoj kev ua haujlwm ntawm kev tuav pov hwm valve: Lub qhov cub siab yog 1540, qhov casting formability yog qhov zoo, thiab cov pov thawj ntawm castings yog feem ntau 2.5%. Nws yog tsim nyog los xav txog qhov tsim ntawm kev siab, kev npaj ntawm pouring riser thiab xaiv ntawm molding cov ntaub ntawv. Thaum lub casting dimension yog biased, nws muaj peev xwm raug kho tom qab kho cua sov, thiab lub cua sov kev kho mob yuav tsum tau nqa tawm tom qab rectification.

Piv nrog rau lwm yam grey hlau castings, cov txheej txheem tsim ntawm valve castings muaj cov nram qab no cov yam ntxwv:

Shan Valve Castings manufacturing process thiab kev soj ntsuam txheej txheem ntau dua.

Lub voj voog ntawm lub vos castings yog ib lub plhaub uas tawv nyias khov. Nws cov castings yuav tsum tau ib qhov dej saum npoo, nrum clarity, tshwj xeeb tshaj yog lub ceev ntig. Yuav ua kom tau raws li cov kev cai saum toj no, casting yuav tsum tau siv ntau yam kev ntsuas, xws li xaiv cov khoom ci siab zoo thiab tswj cov dej hauv cov xuab zeb, molding yuav tsum tau faj seeb los xyuas kom meej tias cov xuab zeb hardness, siv lub hau tsim nyog- thiab lub qhov ncauj qhov ncauj thiab tswj kev nrawm ntawm kub ceev thiab kub. Vim muaj kev kawm siab,

Cov txheej txheem casting ntawm valve castings yog qhov teeb meem ntau dua li ntawm txoj kev pov thawj.

Tsis tas li ntawd xwb, qhov kev sib tw ntawm ntxiv rau qhov kev kuaj loj, qhov chaw qhov tseeb thiab qhov muag, thiab qee yam kuj rau cov qauv metallographic, cov khoom siv dag zog, kev txhuam thiab qhov kev ntsuas tsis zoo thiab kev sim ntsuas, thiab yog li ntawd lub vauj castings soj ntsuam txheej txheem kuj tseem nyuaj.

Shan valve castings yog qhov nyuaj rau nruab rau ntawm cov cuab yeej siv tshuab

Cov qauv thiab cov duab ntawm cov nplaum valve yog complex, thiab qee qhov chaw muaj nyias cov phab ntsa, qhov chaw thiab qhov rigidity tsis zoo. Thaum ua haujlwm ntawm cov khoom siv tshuab, qhov chaw thiab clamping tsis yooj yim, yog li tsim tshwjxeeb ntau qhov tsim nyog.

Qee qhov chaw siv lub tshuab, qhov chaw pib ntawm qhov chaw ntom nti yog qhov tsawg dua, qhov chaw roughness siab dua, thiab qee zaus txawm tias siv cov kev ua haujlwm uas tsis muaj kev ua haujlwm. thiab kev ua haujlwm ntawm lub hau thiab lwm qhov chaw ntawm qhov kev txiav txim siab thiab qhov kev xav tau ntawm qhov yuav tsum muaj siab heev, nws tsis yooj yim los xyuas kom zoo dua. Yog li, kom thiaj li ua tau raws li qhov xav tau ntawm tus txheej txheem, feem ntau nws tsim nyog los txhim kho qhov tseeb ntawm lub hauv paus sab qhov thiab txo qhov chaw npau taws, los yog nyob ntawm qhov chaw ntawm qhov chaw ntawm lub hauv paus, uas ua rau kom tsis yooj yim dua cov txheej txheem kev tsim cov khoom siv.

Shan machining yog nyuaj.

Los ntawm ntau hom valve khoom castings, ntxiv rau ntau hom cam khwb cia hlau, carbon steel, feem ntau ntawm nws cov high-lub zog, corrosion-resistant thiab cov ntaub ntawv tawv txiav kev kawm yog heev txom nyem, nws yog qhov nyuaj ua kom tiav machining precision thiab deg roughness. Qhov kev txiav txim geometrical thiab saum npoo ntawm qhov sealing ntawm lub vos castings yog siab heev, yog li cov kev ua haujlwm nyuaj ntawm cov valve castings yog nce. Nyob rau tib lub sijhawm, qhov kev ua tiav ntawm cov ntaub ntawv pov npav yog pluag, thiab nws coj tau ntau yam teeb meem tshiab rau txoj kev ua haujlwm ntawm lub plhaub tawb, cov khoom siv, kev txiav tshuaj, cov khoom siv thiab lwm yam.
