Welding Process Impact paBara Valve Performance
Kukosha kwewelding process
Maviri-chidimbu bhora mavharuvhu anowanzo kubatanidzwa kune mapaipi ne welding, iyo inovimbisa kuiswa chisimbiso uye kuvimbika kwehurongwa. Kusarudzwa uye kuurayiwa kwehutano hwekugadzirisa welding zvakananga zvinotarisa kugadzikana kwevhavha-pombi yekubatanidza, kuvhara kwechisimbiso uye kunotevera kushanda kwekushanda. Iyo yakakodzera welding process inogona kukwidziridza kushanda kwevhavha yebhora-mbiri uye kuwedzera hupenyu hwayo hwebasa.
Mhedzisiro yewelding process pakuita kwe-two-piece bhora mavharuvhu
Kuumbwa kwenzvimbo yakakanganiswa nekupisa
Munguva yekugadzira, kutonhora kwakanyanya kunokanganisa zvinhu zvemukati munzvimbo iri padyo nevhavha yebhora-mbiri, ichigadzira nzvimbo inopisa. Chimiro chesimbi munzvimbo ino chichachinja, izvo zvinogona kutungamira mukuderedzwa kwesimba rezvinhu, kuwedzera brittleness, uye kunyange microcracks, inokanganisa kumanikidza kuramba uye kuvhara kwevhavha.
Stress concentration dambudziko
Kusaita welding process inoburitsa kusaenzana tembiricha kugovera muvharuvhu uye pombi system, zvichikonzera kusara kunetseka mushure mekutonhora. Izvi zvinoshungurudza zvinogona kuiswa muzvikamu zvakati zvevhavha, kunyanya munzvimbo ye weld, zvichiita kuti nzvimbo idzi dziwedzere kunetseka nekuora mwoyo uye kuneta kukanganisa.
Kukuvadza kwekuita chisimbiso
Iyo tembiricha yepamusoro inogadzirwa panguva yewelding inogona kukuvadza chisimbiso chevhavha, kunyanya kana vharuvhu inoshandisa zvinyoro zvekuisa chisimbiso (senge mapolymers kana rubber). Tembiricha yakakwira inogona kuita kuti chisimbiso chidzikire uye chirasikirwe nekusimba kwayo kwepakutanga uye kugona kuvhara.
Valve deformation
Kusaita welding mashandiro anogona kukonzera deformation yembiri-chidimbu bhora vharafu muviri. Iyi deformation inogona kushandura maitiro ekutanga emagetsi evhavha yebhora, inokanganisa kuvhura kwayo nekuvhara kwayo, uye nekudaro inokanganisa kuyerera kwekudzora maitiro.
Zvinokurudzira zvekugadzirisa welding maitiro
Kusarudza nzira yakakodzera yewelding
Maererano nezvinhu uye mamiriro ekushanda evhavha yebhora-chidimbu, sarudza nzira yakakodzera yekugadzira, yakadai seTIG (tungsten inert gas welding), MIG / MAG (simbi inert gas / metal active gas welding) kana arc welding. Imwe neimwe welding nzira ine yayo chaiyo chiyero chekushandisa uye zvakanakira.
Kudzora welding parameters
Kunyatso kudzora maparamendi ewelding akadai seazvino, voltage, welding kumhanya uye tembiricha zvinogona kuderedza mhedzisiro yenzvimbo yakakanganiswa nekupisa uye kuderedza chizvarwa chekusarira kunetseka.
Shandisa low-hydrogen electrodes
Kusarudzwa kwema-low-hydrogen electrode kunogona kuderedza njodzi yehydrogen embrittlement panguva yewelding uye kunatsiridza kutsemuka kuramba kweweld.
Post-weld kupisa kurapwa
Yakakodzera post-weld kupisa kurapwa kunogona kubvisa kana kuderedza kusara kunetseka, kudzoreredza kuoma kwezvinhu, uye kunatsiridza kushanda kwese kweiyo welded joint.
Welding quality control
Itai maitiro akasimba ekudzora mhando yewelding, kusanganisira kugadzirira kusati kwave, kutarisisa maitirwo ewelding, uye kuongorora mushure mewelding, kuve nechokwadi chekuti mhando yewelding inoenderana nezviyero.
Mhedziso
Iyo welding process ine mhedzisiro yakakosha pakuita kwevhavha yebhora-mbiri. Nekugadziridza maitiro ekuisa chisimbiso, kuvharwa kwechisimbiso, kumanikidza kuramba uye hupenyu hwebasa revhavha inogona kuvandudzwa. Nokudaro, zvakakosha kubhadhara kune zvose zvese zvekugadzirisa uye kutora matanho ekudzivirira anonzwisisika kuti ave nechokwadi chokuti mavharuvhu maviri ebhora anogona kushanda zvakasimba uye akavimbika pasi pemamiriro akasiyana-siyana ekushanda.
