Zvakanakira zve cryogenic kurapwa kwemavharuvhu uye mamiriro eiyo maindasitiri ekushandisa

Tembiricha yakaderera cryogenic processing tekinoroji inogona kuvandudza zvakanyanya hupenyu hwesevhisi yezvishandiso ndeiyi: yakakwirira-kumhanya simbi, chishandiso simbi, die simbi, mhangura electrode, upfu zvinhu, hard alloy, ceramic, etc. Mienzaniso yekushandiswa kwe cryogenic kurapwa kuti irebe hupenyu hwesevhisi hwezvikamu nemamwe makambani ekuAmerica uye mamwe maChinese units anoratidzwa muTafura 2 uye Tafura 3, zvichiteerana. Tafura 4 inoratidza yakaenzana coefficient yekupfeka kuramba shanduko yezvimwe zvinowanzoshandiswa kufa zvinhu mushure mekurapa cryogenic. Inogona kuwedzera kupikisa kupfeka; Wedzera simba uye kuoma; Kuvandudza kusagadzikana kwekuora, kupfeka kusagadzikana; Enhad impact resistance; Kuwedzera kuneta simba…
Kubatana kwepamusoro: Valve cryogenic kurapwa musimboti uye kushandiswa kwayo muindasitiri (2)
Zvakanakira uye kushandiswa kwemaindasitiri kwe cryogenic kurapwa
3.1 Mabhenefiti makuru ekurapa cryogenic
Inogona kuwedzera kupikisa kupfeka; Wedzera simba uye kuoma; Kuvandudza kusagadzikana kwekuora, kupfeka kusagadzikana; Enhad impact resistance; Kuvandudza simba rekuneta; Mushure mekurapwa kwecryogenic, inogona kuve nechokwadi kuti iyo yakarapwa zvinhu inogara ine yakagadziridzwa michina zvinhu; Haakonzeri chimiro saizi deformation; Inogona kuiswa kune itsva / yakashandiswa workpiece; Inogona kubvisa kushushikana kwemukati; Kuvandudza kugadzikana kwezvinhu; Mutengo wekugadzirisa wakaderera, nekuti kurebesa hupenyu hwechishandiso kunogona kuderedza nguva yekuchinja kwechishandiso uye kukuya, kuitira kuchengetedza mutengo wekugadzira; Inogona kuwana mibairo yakafanana semamwe marapirwo epamusoro (akadai seChin plating, chrome, Teflon); Zvimiro zvakasimba zvemamorekuru zvinogona kugadzirwa, zvichideredza kupokana, kupisa uye kupfeka panzvimbo dzakakura dzekusangana.
3.2 Iyo huru workpiece inogona kugadziriswa ne cryogenic treatment
Cutting tool; Internal combustion injini zvikamu; * * * tube; Tap; Transmission shaft; Zviridzwa zvekurapa; Bit; The crankshaft. Zvekurima michina accessories; Milling cutter; CAM; Musical Instruments; Indexable blade; Axis; Simbi isina ngura; Die; Gear; Nickel base alloy; Progressive kufa.

3.3 Main maindasitiri mashandisirwo ekurapa cryogenic
3.3.1 Wedzera hupenyu hwesevhisi yezvikamu uye maturusi uye uvandudze kusakara kwekupfeka
Tembiricha yakaderera cryogenic processing tekinoroji inogona kuvandudza zvakanyanya hupenyu hwesevhisi yezvishandiso ndeiyi: yakakwirira-kumhanya simbi, chishandiso simbi, die simbi, mhangura electrode, upfu zvinhu, hard alloy, ceramic, etc. Mienzaniso yekushandiswa kwe cryogenic kurapwa kuti irebe hupenyu hwesevhisi hwezvikamu nemamwe makambani ekuAmerica uye mamwe maChinese units anoratidzwa muTafura 2 uye Tafura 3, zvichiteerana. Tafura 4 inoratidza yakaenzana coefficient yekupfeka kuramba shanduko yezvimwe zvinowanzoshandiswa kufa zvinhu mushure mekurapa cryogenic. Sezvinogona kuonekwa kubva pamatafura matatu anotevera, cryogenic treatment inogadzira zvakasiyana-siyana pazvikamu uye zvishandiso zvezvinhu zvakasiyana-siyana, uye kupfeka kwekudzivirira kwezvikamu uye zvishandiso kunovandudzwa zvakanyanya.
Tafura 2 Mienzaniso yemamwe makambani muUnited States anoshandisa cryogenic kurapwa kuwedzera hupenyu hwebasa rezvikamu
Tafura 3 Mienzaniso yehupenyu hwebasa repamba cryogenic kurapwa yakakwirira workpieces
Tafura 4 Hupenyu hunochinja mold mushure mekurapa cryogenic
Tafura 5 Kugadzirwa kwemumunda uye mhedzisiro yebvunzo ye cryogenic kurapwa
3.3.2 Kuvandudza kugadzikana kwezvinhu
Kuvandudza kugadzikana kwezvinhu ndeimwe nzira yakabudirira yekurapa cryogenic mualuminium, mhangura, Chin uye 300 dzakatevedzana masimbi asina tsvina, kunyanya aluminium uye alloys ayo.
3.3.3 Kuvandudza zvinhu zvekushandisa
Cryogenic treatment inogona kuwedzera nekuvandudza zvinhu zvenyama, zvakadai sesimba, kuneta kuramba, corrosion resistance, etc. Tafura 5 inoratidza mibairo yemumunda yakawanikwa kubva mukushandiswa kwetsvakiridzo yeyunivhesiti uye tsvakiridzo yeindasitiri mukugadzirwa kwemaindasitiri.
Nekuvandudzwa kweindasitiri yemazuva ano, zvinodiwa zvezvinhu zvenyama zvakakwirira uye zvakakwirira. Pane maitiro maviri makuru ekutsvagisa zvinhu zvemazuva ano:
① Gara uchigadzira matekinoroji matsva, maitiro matsva uye michina mitsva yekugadzira zvakasiyana-siyana zvezvinhu zvitsva zvine zvakakosha kana zvivakwa zvakanakisa, sekukurumidza kusimba, mechanical alloying, jet deposition, jet molding uye mamwe maitiro ekugadzira microcrystalline, amorphous, quasicrystal, nanocrystalline. zvinhu zvekugadzira uye zvinoshanda.
② Kune izvo zviripo zvechinyakare zvinhu zvakaita sesimbi nesimbi, aluminium, mhangura uchishandisa ultra-pure kucheneswa, hombe deformation processing, cryotreatment uye imwe yakakosha yekugadzirisa uye kugadzirisa tekinoroji, mune yekutanga haishandure kuumbwa kwezvinhu zviripo pahwaro hwe. inonatsiridza zvikuru mashandiro ayo, kuitira kuti inyatso kuvandudza mashandisirwo uye kudzoreredza zviwanikwa. Panguva imwecheteyo, zvinhu zvekushandisa zvinogona kuvandudzwa, uye mari inogona kuderedzwa kuderedza kukuvadza kune zvakatipoteredza, izvo pasina mubvunzo zvinopa nzira yakanaka yekugadzirisa kuwedzera kwakanyanya kwesimba uye matambudziko ezvakatipoteredza. Saka zvidzidzo zvezvinhu zvecryogenic kurapwa zvichava zvakakosha tsvakurudzo nhungamiro yevashandi vezvesayenzi kumba uye kunze kwenyika, asi kugadzikana kwekutsvakurudza kuripo zvose mu cryogenic kurapwa kwacho uye nzira yekuita kwezvimwe zvinhu tsvakurudzo zvichiripo kukanganisa kwakawanda, nokuti hombe-pamwero uye kushandiswa kwe cryogenic kurapwa pamaindasitiri kwakaunza zvipingamupinyi, Naizvozvo, kukura uye tsvakurudzo yakagadzikana cryogenic process system uye cryogenic treatment mechanism yesimbi isina ferrous ichava iyo pfungwa yekutsvakurudza munharaunda iyi.
Nekuvandudzwa kwesainzi uye tekinoroji uye hupfumi, kutsanangurwa kwevharuvhu kuri kuwanda, uye mitsva uye yakakosha mhando dzevharuvhu dzakabuda, dziri kure nekure kweiyo vheji yakafukidzwa neiyo iripo valve modhi yekuunganidza nzira JB / T 308 munyika yedu. . Iyo yakabatana nzira yevharuvhu modhi yekubatanidza inoita basa rakakosha mukukurumidzira kusimudzira kwekubatana kweindasitiri yevharuvhu, kuwedzera kuvandudza ketani yeindasitiri, uye kugara ichinatsa kupatsanurwa kwevashandi.
Kutanga, basa remuenzaniso wevharuvhu
Nekuvandudzwa kwesainzi uye tekinoroji uye hupfumi, kutsanangurwa kwevharuvhu kuri kuramba kuchiwedzera, uye akasiyana mavharuvhu matsva uye akakosha ari kubuda, ayo ari kure nekure kweyevhavhavha yakafukidzwa neiyo iripo valve modhi yekuunganidza nzira JB/T 308 mu. nyika yedu. Iyo yakabatana nzira yevharuvhu modhi yekubatanidza inoita basa rakakosha mukukurumidzira kusimudzira kwekubatana kweindasitiri yevharuvhu, kuwedzera kuvandudza ketani yeindasitiri, uye kugara ichinatsa kupatsanurwa kwevashandi.
Panguva imwecheteyo, nekuda kweindasitiri yevharuvhu iri kuwedzera kukwikwidza kunotyisa, imwe neimwe yakakura vagadziri vevharuvhu kumba nekune dzimwe nyika kuitira kuti ichengetwe mupetroleum, kemikari, magetsi emagetsi uye mamwe makuru ekubhidha mapurojekiti maitiro anogona kuwedzera hunhu hwezvigadzirwa zvavo, kudzivirira. zvido zvavo zvehupfumi, kazhinji havashandisi yakabatana JB/T 308 vharafu modhi yekugadzwa nzira, ne sui generis vharafu modhi yekugadzwa nzira.
Vaviri, JB/T 308-2004 modhi yekugadzirira nzira
JB/T 308-2004 Valve Model Preparation Method inoshandiswa pakugadzira modhi yemavharuvhu, globe mavharuvhu, throttle mavharuvhu, butterfly mavharuvhu, bhora mavharuvhu, diaphragm mavharuvhu, plug mavharuvhu, cheki mavharuvhu, ekuchengetedza mavharuvhu, kumanikidza kuderedza mavharuvhu, matepi emhepo. , blowdown mavharuvhu, plunger mavharuvhu uye zvimwe zvigadzirwa mune zvakajairika mavharuvhu.
Iyo valve model inotsanangurwa neJB/T 308-2004 inoumbwa nezvinhu zvinotevera: valve type, drive mode, connection form, form form, sealing surface material or lineing material type, pressure code or working pressure code pakushanda tembiricha, valve body. zvinhu uye zvimwe zvikamu zvinomwe.
