Kusala zibelesyo zyakujala mavalvu

Busena bwakujala mavalvu aabutale (DC341X-16 Ivalvu iijisi zibeela zyobile) kanjikanji ilapangwa a (TWS valve)kuwelda atala. Zintu zibelesyegwa kubamba mavalvu zyaandaanizyigwa muzibeela zyone zipati kweendelanya amusyobo wa alloy, eezyo zipangidwe a cobalt, nickel, iron, antoomwe a copper. Eezyi zintu zya alloy zipangwa kuba ma electrode, ntambo zyakuwelda (kubikkilizya ntambo zya flux-cored), fluxes (kubikkilizya a transition alloy fluxes) antoomwe ama alloy powders, azimwi, mpawo zilabikkwa atala kwiinda mukubelesya nzila ya manual arc welding, oxyacetylene flame welding, tungsten argon arc welding, submerged arc automatic arc welding antoomwe a plastic arc welding.

Kusala kwazibelesyo zyakujala mavalvu (DC341X3-10Ivalvu ya butterfly iijisi zibeela zyobilenkomo yakujala mubili) kanjikanji iyeeme akupya kwakubelesya, nguzu zyakubeleka akubola kwa vvalavu, naakuti musyobo wa vvalavu, bupange bwabusena bwakujala, muya wakujala abulemu buzumizyidwe, naakuti bukkale bwakupanga akupanga bwakkampani, nguzu zyakupanga zibelesyo antoomwe akukonzya kwakubelesya zibelesyo. Bupange buli kabotu bweelede kubelesegwa, mpawo zintu zyakujala zili aamuulo muniini, nzila nguba yakupanga akuchita obotu zyeelede kusalwa muchiimo chakuzuzikizya mulimo wa (D341X3-16 Valv iijisi zibeela zyobilee )valve.

Zimwi zintu zibelesyegwa kujala zibeela zya valve zili buyo amusyobo omwe, naa electrode naa welding wire naa alloy powder, aboobo nzila yomwe buyo yakubamba njiikonzya kubelesyegwa. Zimwi zipangwa kuba nkoli zyakuwelda, ntambo zyakuwelda naakuti busi bwa alloy munzila zisiyene, mbuli stellite l 6 alloy, zyoonse zyobile welding rods (D802), welding wires (HS111) antoomwe a alloy powders (PT2102), mpawo manual arc welding, oxy2acetylene flame welding, tungsten argon argon arc welding plasma arc welding plasma kuwelda azimwi nzila zilakonzya kubelesegwa kuwelda atala. Notusala zibelesyo zyakujala bulo, tweelede kubikkila maanu kukusala nzila yakubamba bulo bujisi tuncini tusimide, nzila nguba-uba alimwi akubeleka kabotu kwakkampani, kuchitila kuti kube kuzuzikizyigwa kwakubeleka kwayo mukupanga bulo bwakujala bulo.

Busena bwakujala mbusena bupati bwa valve (D371X-10 Wafer butterfly valve), mpawo bubotu bwayo bulajatikizya buumi bwa valve. Kusala kabotu kwazibelesyo zyakujala vvalavu ninzila imwi iiyandika yakusumpula buumi bwa vvalavu. Kutamvwisisisya kweelede kutantamukwa mukusala zibelesyo zyakujala mavalvu.

Makani aakubeja 1: Kuyuma kwavalvu (D371X3-16C) zyakujala atala zilisumpukide, mpawo kukazyigwa kwazyo nkubotu.

Kusola kutondeezya kuti kukazyigwa kwakusama kwachintu chakujala vvalavu kulayeeme abwaanda bwachibulo. Zimwi zintu zyabutale zili a austenite mbuli matrix antoomwe aabupange buniini bwa hard phase tazili ziyumu pe, asi kukazyigwa kwazyo nkubotu loko. Busena bwakujala bwa valve buli abuyumuyumu bupati kutegwa butachisyi akukwasigwa azintu ziyumu zili mukati. Zyoonse zyalangwa-langwa, mweelwe wakuyuma HRC35~45 uleelela.

Makani aatali aachoonzyo 2: Muulo wazintu zyakujala mavalvu ulisumpukide, mpawo kubeleka kwawo nkubotu.

Muulo wachintu mbube bwacho, mpawo kubeleka kwacho mbube bwachintu, mpo taakwe kujatana aakati kazeezi zyobile. Insimbi ya cobalt iili mu cobalt-based alloys izwa kuzintu zizwa kunze aacisi, mpawo muulo ulisumpukide, aboobo muulo wa cobalt-based alloys ulaajulu. Ma alloy aapangidwe a Cobalt alazyibwa akaambo kakutakonzya kubola muchiindi chakupya kapati, mpawo kuti abelesegwa mubukkale bwakupya buli kabotu abwaakati aakati, muulo/kubeleka kwawo kulisumpukide. Mukusala zibelesyo zyakujala mavalvu, zibelesyo zitayandiki mali manji zyeelede kusalwa.

Makani aatali aachoonzyo 3: Ikuti naa zintu zyakujala zya valve kazijisi nguzu zyakukazya kubola muchibaka chiyumu, cheelede kuzyibila kuzintu zimwi zibola.

Kukazya kubola kwazintu zyabutale kulijisi nzila yaco iikatazya kumvwisisisya, chintu chili aanguzu zyakukazya kubola muchiimo chiyumu chakubola, mpawo bukkale bulachincha mbichani, mbuli kupya naakuti bunji bwazintu, kukazyigwa kubola kulachinchwa. Kuli chimwi chintu chikonzya kubola, ikukazya kubola kulacinca loko. Kukazya kubola kwazintu zyabutale kulakonzya buyo kuzyibwa kwiinda mukusola, mpawo bukkale bweelede kumvwisisyigwa kuti bubelesyegwe kuzwa kuzintu zijatikizyidwe, alimwi tazyeelede kukweletesyegwa buyo.
