Ububiko bwa kashe ya valve, igiti nigiti cyibikoresho bisobanurwa na valve yaho itegereje ko sosiyete ya valve ifata ingamba zikwiye

Ububiko bwa kashe ya valve, igiti nigiti cyibikoresho bisobanurwa na valve yaho itegereje ko sosiyete ya valve ifata ingamba zikwiye

Ubuso bwa kashe ni urufunguzo rwo gukora rwa valve. Ubwiza bwubuso bufitanye isano nubuzima bwa serivisi ya valve. Mubisanzwe, ibintu bifunga kashe bigomba gutekereza kubirwanya ruswa, kurwanya abrasion, kurwanya isuri, kurwanya okiside nibindi bintu. Ibiti by'uruti bikorerwa mu buryo butaziguye imbaraga za axial mugihe cyo gufungura no gufunga bityo bigomba kugira imbaraga runaka. Mugihe kimwe, ihujwe nuruti, bisaba coefficient ntoya yo guterana, nta ngese kandi wirinde ibintu byo kuruma. INKINGI ZIKURIKIRA ZIFATANYIJE NA MELON ZIKORESHEJWE MU GACIRO CY'AMASHANYARAZI GUSA GUHUZA UBUSHUMBA BUKORESHEJWE CYANGWA CYANGWA CYANE.
Gufunga ibikoresho byo hejuru
Ubuso bwa kashe ni urufunguzo rwo gukora rwa valve. Ubwiza bwubuso bufitanye isano nubuzima bwa serivisi ya valve. Mubisanzwe, ibintu bifunga kashe bigomba gutekereza kubirwanya ruswa, kurwanya abrasion, kurwanya isuri, kurwanya okiside nibindi bintu.
Mubisanzwe hariho ibyiciro bibiri byingenzi:
(1) Ibikoresho byoroshye
1, reberi (harimo reberi ya butadiene, rebero ya fluor, nibindi)
2, plastike (PTFE, nylon, nibindi)
(2) ibikoresho bikomeye byo gufunga
1, umusemburo wumuringa (kuri valve yumuvuduko muke)
2, chromium ibyuma bidafite ingese (kubisanzwe byumuvuduko mwinshi)
3, Sitai alloy (kubushyuhe bwo hejuru hamwe numuvuduko mwinshi hamwe na ruswa ikomeye)
4. Nickel base alloy (kubitangazamakuru byangirika)
Ibikoresho by'ibiti
Uruti rushobora gukururwa, gukanda hamwe na torsional imbaraga mugihe cyo gufungura no gufunga, kandi ihura nuburyo butaziguye mugihe
HARI NUBUNDI BIKURIKIRA BIKURIKIRA HAGATI YO GUKORA, GUKORA IBIKORWA BIKURIKIRA BIGOMBA KUBONA IMBARAGA ZIDASANZWE KANDI BIDASHOBOKA MU GIHE CY'UMWIHARIKO.
Gukomera, kurwanya ruswa no kurwanya abrasion, hamwe nikoranabuhanga ryiza.
Ibikoresho bisanzwe bisanzwe nibi bikurikira.
Ubwa mbere, ibyuma bya karubone
Iyo ikoreshejwe mumazi no mumazi hamwe numuvuduko muke hamwe nubushyuhe bwo hagati butarenga 300 ℃, A5 ibyuma bisanzwe bya karubone byatoranijwe.
Ku muvuduko ukabije n'ubushyuhe bwo hagati ntiburenza 450 ℃ amazi, icyuka gisanzwe, muri rusange hitamo ibyuma 35 bya karubone.
Babiri, ibyuma bivanze
Kumuvuduko ukabije hamwe numuvuduko mwinshi, ubushyuhe buringaniye ntiburenga 450 ℃ amazi, amavuta, amavuta nibindi bitangazamakuru, muri rusange hitamo 40Cr (ibyuma bya chromium).
Kumuvuduko mwinshi, ubushyuhe buringaniye ntiburenga 540 ℃ amazi, amavuta nibindi bitangazamakuru, birashobora guhitamo 38CrMo>
Kumuvuduko mwinshi, ubushyuhe buciriritse ntiburenga 570 medium icyuma gisanzwe, mubisanzwe hitamo 25Cr2MoVA chromium molybdenum vanadium ibyuma.
Bitatu, ibyuma bidafite umwanda
Ku muvuduko wo hagati hamwe n’umuvuduko mwinshi, ubushyuhe bwo hagati ntiburenga 450 ℃ butabora bworoshye kandi bworoshye bubora, burashobora guhitamo 1Cr13, 2Cr13, 3Cr13 chromium ibyuma bitagira umwanda. Kubitangazamakuru byangirika, Cr17Ni2, 1Cr18Ni9Ti, Cr18Ni12Mo2Ti, Cr18Ni12Mo3Ti nibindi byuma bitarwanya aside hamwe na PH15-7mO imvura ikomera ibyuma birashobora gutoranywa.
Bane, ibyuma birwanya ubushyuhe
4Cr10Si2Mo Ubwoko bwa Martensite ibyuma birwanya ubushyuhe nicyuma birashobora gukoreshwa mugihe ubushyuhe buciriritse butarenze 600 ℃
4Cr14Ni14W2Mo Austenitis ubwoko bwicyuma gihanganira ubushyuhe.
Ibikoresho by'ibiti
Ibiti by'uruti bikorerwa mu buryo butaziguye imbaraga za axial mugihe cyo gufungura no gufunga bityo bigomba kugira imbaraga runaka. Mugihe kimwe, ihujwe nuruti, bisaba coefficient ntoya yo guterana, nta ngese kandi wirinde ibintu byo kuruma.
Ubwa mbere, umuringa
Coefficient de coiffure yumuringa ni ntoya, nta ngese, nimwe mubikoresho bisanzwe bikoreshwa. Kuri PG1.6mpa umuvuduko muke wa ZHMN58-2-2 umuringa urashobora gukoreshwa. Kuri PG16-6.4mpa igitutu giciriritse gishobora gukoresha ZQ>
Icya kabiri, ibyuma
Mugihe imiterere yakazi itemerera ikoreshwa ryumuringa wumuringa, urashobora guhitamo 35, 40 ibyuma bya karubone nziza, 2Cr13, 1Cr18Ni9, Cr17Ni2 nibindi byuma bitarwanya aside.
Imiterere yakazi ntabwo yemerewe kwerekeza kuri ibi bikurikira.
1, kuri valve yamashanyarazi, valve stem nut hamwe na melon clutch, igomba gukenera ubushyuhe kugirango ubone ubukana bwinshi cyangwa ubukana bwubuso.
2, uburyo bukoreshwa cyangwa ibidukikije bidukikije ntibikwiriye guhitamo umuringa, nkumuringa wangirika wa ammonia. Mugihe uhitamo ibiti byicyuma, hagomba kwitonderwa byumwihariko kubintu byo kuruma.
Imyaka mike iri imbere izaba inganda za valve mugihe cyihuta cyihuta, ingaruka zitaziguye ziyi mpanuka yihuse nuburyo bugezweho bwa polarisiyasi mu kigo cyabakozi ba valve cyagutse.
Biteganijwe ko mumyaka mike iri imbere ishobora rwose kubaho mumasoko ya valve isoko ntabwo ari menshi.
Ariko inganda za valve iyi mpanuka yihuse izazana amahirwe akomeye, ibisubizo byihungabana bizatuma imikorere yisoko irushaho gushyira mu gaciro.
