Kusankha zipangizo zopangira pamwamba pa malo otsekera ma valve

Malo otsekera ma valve achitsulo (Valavu ya gulugufe ya DC341X-16 yokhala ndi flange iwiri) nthawi zambiri imapangidwa ndi (Valavu ya TWS)kuwotcherera pamwamba. Zipangizo zomwe zimagwiritsidwa ntchito popanga ma valve surface zimagawidwa m'magulu akuluakulu anayi malinga ndi mtundu wa alloy, omwe ndi cobalt-based alloys, nickel-based alloys, iron-based alloys, ndi copper-based alloys. Zipangizo za alloy izi zimapangidwa kukhala ma electrodes, mawaya olumikizira (kuphatikiza mawaya ozungulira), ma fluxes (kuphatikiza transition alloy fluxes) ndi ufa wa alloy, ndi zina zotero, ndipo zimayikidwa pamwamba pogwiritsa ntchito manual arc welding, oxyacetylene flame welding, tungsten argon arc welding, submerged arc automatic welding ndi plasma arc welding.

Kusankha kwa zipangizo zotsekera ma valve pamwamba (DC341X3-10Valavu ya gulugufe yozungulira kawiri(Mzere wotsekera thupi) nthawi zambiri umadalira kutentha komwe kumagwiritsidwa ntchito, kuthamanga kwa ntchito ndi kuwonongeka kwa valavu, kapena mtundu wa valavu, kapangidwe ka pamwamba potsekera, kuthamanga kwa kutsekera ndi kuthamanga komwe kuloledwa, kapena momwe bizinesiyo imagwirira ntchito, mphamvu yogwiritsira ntchito zida ndi luso laukadaulo la pamwamba pake ndi zofunikira za ogwiritsa ntchito. Kapangidwe koyeneranso kuyenera kutsatiridwa, ndipo zinthu zotsekera pamwamba zomwe zili ndi mtengo wotsika, njira yosavuta yopangira komanso magwiridwe antchito apamwamba ziyenera kusankhidwa malinga ndi momwe zimakhudzira magwiridwe antchito a （Valavu ya gulugufe ya D341X3-16 yokhala ndi flange iwirie )valavu.

Zipangizo zina zomwe zimagwiritsidwa ntchito popanga pamwamba pa ma valve sealing pamwamba zimakhala ndi mawonekedwe amodzi okha, kapena electrode kapena welding wire kapena alloy powder, kotero njira imodzi yokha yopangira pamwamba ingagwiritsidwe ntchito. Zina zimapangidwa kukhala ma welding rods, welding wire kapena alloy powders m'njira zosiyanasiyana, monga stellite l 6 alloy, ma welding rods onse (D802), welding wire (HS111) ndi alloy powders (PT2102), kenako ma manual arc welding, oxy2acetylene flame welding, tungsten argon arc welding, wire feeding plasma arc welding ndi powder plasma arc welding ndi njira zina zingagwiritsidwe ntchito popanga surfacing welding. Posankha zipangizo zopangira pamwamba pa valve sealing surface, tiyenera kuganizira kusankha njira yopangira pamwamba pogwiritsa ntchito ukadaulo wokhwima, njira yosavuta komanso kupanga bwino kwambiri kwa bizinesi, kuti tiwonetsetse kuti ikugwira ntchito bwino popanga surfacing surface.

Malo otsekera ndiye gawo lofunika kwambiri la valavu (Valavu ya gulugufe ya D371X-10 Wafer), ndipo khalidwe lake limakhudza mwachindunji moyo wa ntchito ya valavu. Kusankha bwino zinthu zomwe zili pamwamba pa valavu yotsekera ndi njira imodzi yofunika kwambiri yowonjezerera moyo wa ntchito ya valavu. Kusamvetsetsana kuyenera kupewedwa posankha zinthu zomwe zili pamwamba pa valavu yotsekera.

Bodza 1: Kulimba kwa valavu (D371X3-16C) Zomangira pamwamba pake ndi zapamwamba, ndipo kukana kwake kukalamba ndikwabwino.

Mayeso akusonyeza kuti kukana kwa kutopa kwa zinthu zotsekera pamwamba pa valavu kumatsimikiziridwa ndi kapangidwe kake ka chitsulo. Zipangizo zina zachitsulo zokhala ndi austenite ngati matrix ndi kapangidwe kakang'ono ka gawo lolimba sizovuta kwambiri, koma kukana kwawo kutopa ndikwabwino kwambiri. Malo otsekera pamwamba pa valavu ali ndi kuuma kwakukulu kuti asavulale ndikukanda ndi zinyalala zolimba zomwe zili mkati. Poganizira zonsezi, kuuma kwa HRC35~45 ndikoyenera.

Bodza Lachiwiri: Mtengo wa zinthu zotsekera ma valve pamwamba ndi wokwera, ndipo magwiridwe ake ndi abwino.

Mtengo wa chinthu ndi khalidwe lake la katundu, pomwe magwiridwe antchito a chinthu ndi khalidwe lake lakuthupi, ndipo palibe ubale wofunikira pakati pa ziwirizi. Chitsulo cha cobalt chomwe chili mu alloys zochokera ku cobalt chimachokera kumayiko ena, ndipo mtengo wake ndi wokwera, kotero mtengo wa zinthu zochokera ku cobalt ndi wokwera. Alloys zochokera ku cobalt zimadziwika ndi kukana kuvala bwino kutentha kwambiri, pomwe zikagwiritsidwa ntchito kutentha kwabwinobwino komanso kwapakati, mtengo/magwiridwe antchito ndi okwera. Posankha zinthu zotsekera pamwamba pa valavu, zinthu zomwe zili ndi mtengo/magwiridwe antchito otsika ziyenera kusankhidwa.

Bodza Lachitatu: Ngati zinthu zotsekera pamwamba pa valavu zili ndi kukana dzimbiri bwino mu malo amphamvu owononga, ziyenera kusinthasintha kuti zigwirizane ndi zinthu zina zowononga.

Kukana dzimbiri kwa zinthu zachitsulo kuli ndi njira yakeyake yovuta, chinthu chimakhala ndi kukana dzimbiri bwino mu chinthu champhamvu chowononga, ndipo zinthu zimasintha pang'ono, monga kutentha kapena kuchuluka kwapakati, kukana dzimbiri kumasinthidwa. Pa chinthu china chowononga, kukana dzimbiri kumasiyana kwambiri. Kukana dzimbiri kwa zinthu zachitsulo kungadziwike kokha kudzera mu zoyeserera, ndipo zinthu zoyenera ziyenera kumvedwa kuti zigwiritsidwe ntchito kuchokera kuzinthu zoyenera, ndipo siziyenera kubwerekedwa mwachisawawa.
