Ibintu by'ingenzi byakunzwe

• Gukata hakoreshejwe uburemere bifata icyo gukata hakoreshejwe uburebure bidashobora: ubucucike bw'ibice n'ubugari bw'impapuro biratandukanye, bityo uburebure bungana ntibukunze gutanga uburemere bungana.
• Imashini yo gukata uburemere ya XCJ-A 600 ihuza sensor y’uburemere ya LASCAUX hamwe na Delta PLC control, ikagabanya ku buryo umukoresha ashobora kuyikoresha kandi igatondekanya buri gice mu buryo bwikora.
• Gukata imiterere y’ibikoresho kugeza ku idirishya rito cyane (urugero: ± 0.3 g) bigabanya imyanda y’ibikoresho biremereye cyane n’ibisigazwa by’ibikoresho bidakomeye icyarimwe.
• Shyira ibice by'ingenzi kuri buri mashini (6 cyangwa 10) kuri ecran ikoraho hanyuma imashini igatanga umubare nyawo, ikuraho kubara intoki no gufata kabiri.

Impeta za O-ring ni zo zikoreshwa cyane mu nganda zikora kabutike, kandi buri mpeta ya O-ring ikoze mu buryo bwa "flash" ijyana urumuri ku murongo wayo wo kuyitandukanya. Guhitamo imashini ikoresha "deflashing" bigira ingaruka ku miterere y'ubwiza bwa "O-ring" gusa, ahubwo bigira ingaruka ku mikorere yayo yo gufunga, imiterere yayo, n'ikiguzi cyo kuyikora. Iyi mfashanyigisho itanga uburyo bwo guhuza ibikoresho bikoresha "deflashing" n'ibipimo byo gukora "O-ring".

Ibisabwa mu gusohora irangi rya O-Ring: Ni iki gituma ritandukana n'ibindi bice bya rubber

Impeta za O-ring zitera imbogamizi nyinshi zo gukuraho ubushyuhe zitaboneka mu bindi bicuruzwa bya kabutike. Kubera ko ifuro rimwe rya O-ring ritanga umwobo mwinshi cyangwa amagana, urumuri rw'umurongo utandukanya runyura ku murambararo w'imbere n'uw'inyuma wa buri mpeta. Igice gito cy'impeta za O-ring gisanzwe kiri hagati ya mm 1.5 na mm 8.4 kuri buriISO 3601-1— bivuze ko urumuri ruri hafi y'ubuso bukora bwo kuziba. Gukuraho ibintu by'ibanze ku ihuriro ry'urumuri bitera inzira y'amazi idashobora kugaragara hakoreshejwe igenzura ry'amaso gusa.

Byongeye kandi, impeta za O zishyirwa mu byiciroASTM D1414ku buryo busanzwe bwo gupima, bugaragaza uburyo bwo kugenzura ingano y'ibipimo ko gusohora ifu bitagomba kubangamira.ISO 3302-1, ubushobozi bwo kwihanganira imiterere y'impeta za O bushobora kuba hagati ya ± 0.08 mm ku bice biri munsi ya mm 2.5 kugeza ± 0.22 mm ku bice biri hejuru ya mm 10. Uburyo bwo gukuraho urumuri bugomba gukuraho urumuri nta guhindura ibi bipimo by'ingenzi.

Ikintu kitagaragara cyane ariko gifite akamaro kanini ni aho urumuri ruherereye. Ibyuma bya O-ring ubusanzwe bifite umurongo utandukanya hagati y’ibyuma, bivuze ko urumuri rwicaye neza ku murambararo w’urupapuro. Gukuraho umwuka usiga igisigazwa kiri hejuru ya mm 0.1 kuri ID cyangwa OD bitera inenge yo gufunga itera kuva kw’amazi ku gitutu cy’inyuma. Iyi ngingo ituma guhitamo uburyo bwo gukuramo umwuka ukoresheje O-rings biba ingenzi cyane ku bice bya O-rings kuruta ku bice bya rubber bifite imiterere idasanzwe aho urumuri rutari ku buso bukora.

Ibintu bitanu byo gufata ibyemezo mu guhitamo imashini ikoresha icyuma gikuraho imipira ya O-Rings

Ikintu cya 1: Ingano y'impeta ya O n'igice cyayo

Ingano y'impeta za O-rings zawe ni yo igena imbogamizi za mbere ku bikoresho. Imashini zikoresha ibyuma bisukura ingoma zikora mu rugero rwa metero imwe n'imwe.Imashini yo gusohora ingoma ya XCJ-G600, ifite umurambararo wa mm 600 z'ingoma n'ubushobozi bwa kg 15, itunganya impeta za O-ring kuva kuri mm 3 kugeza kuri mm 100 z'ubugari bwo hanze. Impeta za O-ring zitari munsi ya mm 3 zikunda kunyura mu cyuho cy'ingoma cyangwa mu kiraro mu matsinda, bigagabanya ubushobozi bwo kuzikuramo. Impeta za O-ring zirenze mm 100 z'ubugari zisaba ingoma nini cyangwa ubundi buryo bwo kuyikoresha.

Impande zombi nazo ni ingenzi. Impeta ntoya za O zifite ibice biri munsi ya mm 2 zishobora gukonja no kwangirika kw'ubuso mu gihe cyo kugwa kw'imashini. Kuri izi, gutunganya cryogenic ni amahitamo meza kuko irangi ikonje ikora nk'ikintu gikomeye mu gihe cyo gukubitwa n'ibice. Itegeko rifatika dukoresha mu ruganda rwacu:Impeta za O-ring zifite ibice ≥2.5 mm na OD iri hagati ya mm 8 na mm 80 ni zo zikwiriye gukoreshwa mu gusohora ingoma mu buryo bwa mechanical, mu gihe impeta za O-ring zitari kuri uru rwego zigomba gusuzumwa kugira ngo zikoreshwe mu buryo bwa cryogenic.

Ikintu cya 2: Imiterere y'urumuri n'ubwoko bw'ibikoresho

Ubugari bwa Flash ni cyo gipimo cy'ingenzi cyane cy'imikorere. Gukuraho ibyuma bikora neza iyo igipimo cy'ubugari bwa flash-to-part ari 0.1 cyangwa irenga - bivuze ko impeta ya O-section ya 3.5 mm ifite flash ya 0.35 mm ishobora guseswa mu buryo bwa mashini, mu gihe impeta ya 1.8 mm ifite flash ya 0.15 mm idashobora guseswa. Ku mpeta za O-section zikozwe mu bikoresho bifite cavitation nini aho flash isanzwe iba 0.1-0.3 mm, ibikoresho ni byo bigena niba deflashing ya mechanical cyangwa cryogenic ikwiye.

Ubunini bw'urumuri bupimirwa ku gice cy'ubunini cyane cy'umurongo utandukanya ibumba. Ingano nyayo ishobora gutandukana bitewe n'uburyo ibumba rikozwemo n'imiterere yaryo.

Ikintu cya 3: Ingano y'umusaruro n'ingano y'itsinda

XCJ-G600 itunganya ibiro 15 by'impeta za O mu masegonda 20-40 kuri buri ruziga. Ku buremere bwa O-ring bungana na garama 2-10 bitewe n'ingano, itsinda rimwe rigizwe n'impeta za O 1.500-7.500. Ku masegonda 40 kuri buri ruziga hamwe n'impeta zishyirwa hejuru, umusaruro mwiza ni hafi 60-80 kuri buri ruziga rw'amasaha 8, cyangwa 90.000-600.000 kuri buri ruziga bitewe n'ingano.

Umusaruro mwinshi urenga impeta za O-rings 500.000 ku munsi ushobora gutuma habaho umurongo wihariye w’ingufu zikora ku ngano nto n’umurongo w’ingufu ku bwoko bw’ingenzi, ariko ku bakora ingoma baciriritse benshi, imashini imwe y’ingufu ikora 80-90% by’ingufu za O-ring.Impeta 10-20% zisigaye — akenshi zikozwe muri silicone cyangwa sub-6 mm ID O-rings — zishobora gutangwa hanze cyangwa zigakoreshwa ku mashini ntoya ikora cryogenic batch.

Ikintu cya 4: Icyiciro cy'ubworoherane n'ibisabwa ku bwiza

ISO 3302-1 ishyira mu byiciro bine ubushobozi bwo kwihanganira ibikoresho bya rubber. Icyiciro cya A (ubuziranenge) gisaba ± 0.08 mm ku bice biri munsi ya mm 2.5. Icyiciro cya B (gito) gisaba ± 0.10 mm. Icyiciro cya C (giciriritse) gisaba ± 0.14 mm. Uburyo bwo gukuraho urumuri bugomba kuba bushobora gukuraho urumuri mu gice cyo kwihanganira hatabayeho kugabanya igice kiri munsi y'ingano yemewe. Gukuraho ibyuma hakoreshejwe uburyo bukwiye bwo guhitamo ibyuma bipima neza bigeraho ubushobozi bwo kwihanganira icyerekezo cya B na C buri gihe. Gukuraho ibyuma bipima neza, hamwe no gukuraho ibikoresho bigenzurwa neza, bigeraho ubushobozi bwo kwihanganira icyerekezo cya A na B ku mpande za O zifite ibice bito.Niba uburyo bwawe bwo gukoresha impeta ya O-ring busaba ko habaho ubushobozi bwo gupima ibice biri munsi ya mm 3, gukoresha cryogenic deflashing ni byiza cyane.

Ikintu cya 5: Ikiguzi cyose cy'ibikorwa (TCO)

Ibice bibiri by'ikiguzi bikunze gusuzugurwa mu guhitamo imashini zikoresha amashanyarazi: ikoreshwa ry'ibikoresho n'ibikoresho bya azote y'amazi. Gukoresha amashanyarazi akoreshwa mu ikoranabuhanga bikoresha ibyuma bigwa (udupira twa pulasitiki cyangwa uduce twa walnut) bisaba gusimburwa buri gihe. Gukoresha amashanyarazi akoreshwa mu ikoranabuhanga bikoresha azote y'amazi ku kigero cya 0.5-2.5 kg kuri kilo ya rubber itunganyijwe, bitewe n'uburemere n'ubucucike bw'ibice.

Ibiciro bishingiye ku bipimo bya 2026 Cinque ku bikoresho bikorera mu Bushinwa. Ibiciro bya LN2 biratandukanye mu karere; gutanga ibikoresho byinshi bigabanya ikiguzi ho 15-25%.

Uburyo bwo gufata ibyemezo: Ni iyihe mashini ikuraho imipira ya O-Rings ijyanye n'umusaruro wawe?

Inganda nyinshi zikoresha uburyo buvanze: imashini ya XCJ-G600 ikora imashini ikuraho ingoma ikora NBR na EPDM, mu gihe imashini nto ikora imashini itunganya silicone na FKM O-rings bingana na 10-20% by'umuvange w'ibicuruzwa. Iyi gahunda ituma ibikoresho bikoreshwa cyane birushaho kugerwaho neza mu gihe ikomeza kugira ubuziranenge ku bikoresho byihariye.

Umwanzuro: Huza imashini ikoresha deflashing na portfolio yawe ya O-Ring

Nta mashini imwe nziza yo gusohora irangi ku mpande za O. Guhitamo neza biterwa n'ingano ya O-ring, ubwoko bw'ibikoresho, imiterere ya flash, ingano y'umusaruro, n'ibisabwa mu kwihanganira. Gusohora irangi ku ngoma hakoreshejwe XCJ-G600 ni cyo gisubizo gihendutse cyane ku mpande za NBR na EPDM O zisanzwe mu rugero rwa 6-90 mm OD, bitanga inshuro z'amasegonda 20-40 ku nshuro ya 15 kg kuri buri batch. Gusohora irangi ku buryo bwa cryogenic biba ngombwa ku mpande za silicone na FKM O, imiterere mito iri munsi ya mm 6, hamwe n'uburyo bwo kwihanganira urwego rwa A. Ku bikoresho bivanze, gukoresha uburyo bwombi icyarimwe byongera ubushobozi bwo koroha hatabayeho kwangiza igiciro ku bikoresho bisanzwe.
