Iyo abantu benshi bumvise 'reberi ya rubber,' bashushanya impeta yoroshye yumukara, ikintu cyibicuruzwa. Ngiyo imyumvire ya mbere itari yo. Mubyukuri, guhitamo hagati ya EPDM, Nitrile (NBR), cyangwa Viton (FKM) ntabwo ari ibiciro gusa; bijyanye nuburyo bwo gutsindwa kwinteko yawe yose. Nabonye imishinga myinshi aho ihendutse, rusange Rubber yateje kumeneka nyuma y'amezi atandatu kuko umuntu yazigamye $ 0.50 kuri buri gice akirengagiza urupapuro ruhuza itangazamakuru. Igikuta ni ifarashi ikora, kandi kunanirwa kwayo ni gake cyane - ni igitonyanga gihinduka umwuzure.

Ibikoresho ntabwo ari Rubber gusa

Reka tumenye neza. Kubice bya HVAC byo hanze, EPDM niyo isanzwe kubwimpamvu-ozone nziza kandi irwanya ikirere. Ariko niba icyo gice kiri hafi yinyanja, utangira guhangayikishwa no gutera umunyu. Urusange rufite inyongeramusaruro zihagije zo kurwanya gusaza? Icyiciro twakomereje muri 2019 kubitanga isoko byananiranye compression yashizeho ibizamini imburagihe. Ibikoresho byumvaga ari byiza, byanyuze mu mashusho y'ibanze, ariko kubera igitutu cya flange, byafashe umurongo uhoraho kandi wabuze imbaraga zo gufunga. Nicyo kintu: impapuro zamakuru ni intangiriro, ntabwo ari garanti.

Noneho hariho kurwanya peteroli. Umutego wa kera. Nitrile ikunze gusobanurwa kumavuta ashingiye kumavuta. Ariko, amavuta ntasobanutse neza. Ari hydraulic fluid, mazutu, cyangwa biodiesel? Ibiranga kubyimba biratandukanye cyane. Ndibuka prototype ya moteri ntoya aho NBR isanzwe Rubber yabyimbye hafi 15% muruvange rushya rwa bio-mazutu, bitera gukuraho bidakwiye. Tugomba guhindukira murwego rwohejuru-acrylonitrile NBR. Isomo kwari ukugerageza buri gihe hamwe na fluid nyayo, mubushyuhe bwo gukora.

Kandi kubushyuhe bwo hejuru bwo gusaba, gusimbuka kuva kuri silicone kugera kuri Viton nigwiza ikiguzi. Silicone irashobora gufata 225 ° C, ariko imbaraga zayo zo kurira ntizihagije. Viton ikoresha imiti nubushyuhe bukabije, ariko birakomeye. Ukeneye umutwaro uremereye kugirango ugere kashe ikwiye, ishobora kugoreka flanges yoroheje. Nibibazo bya sisitemu, ntabwo ari ikibazo cya gaseke gusa. Rimwe na rimwe, igisubizo ntabwo ari gaze nziza, ahubwo ni igishushanyo mbonera cya glande cyangwa guhinduranya kashe ya reberi.

Geometrie na Compression: Ibintu byibagiwe

Ibikoresho byuzuye muburyo butari bwo ntacyo bimaze. Durometero (gukomera) igomba guhuza flange yubuso burangiye hamwe nuburemere buboneka bwo kwikuramo. Inkombe 70 Igipapuro hejuru yikibabi, icyuma gishobora gufunga neza, kuko gishobora guhinduka mubidatunganye. Igicapo kimwe hejuru yindorerwamo-yuzuye ibyuma bidafite ibyuma birashobora gukenera kwambukiranya igice kugirango byongere imitwaro.

Twakoze imashini yihariye ya PTFE kugirango ikoreshwe imiti rimwe hanyuma dukoresha gasanzwe kare-igice cya EPDM. Yasohotse. Ikibaho cyari gikomeye kandi cyoroshye. Gukosora ntabwo byari ibintu bishya; kwari uguhindura O-impeta mu gikoni cyakozwe neza (kashe ya elastomeric, yego, ariko ihame rirasa). Uwiteka Rubber yari ikeneye guhagarika guhagarika. Aha niho reberi ihurira n'umuhanda, mubisanzwe - igishushanyo mbonera ni kimwe cya kabiri cyintambara.

Kwishyira hamwe ni umwicanyi. Uhinduranya ibimera, birashiraho kashe. Nyuma yubushyuhe bwumwanya nigihe, reberi ntisubira inyuma. Imbaraga zo gukomera ziratemba. Nkunda gasketi hamwe na selile ya selile cyangwa polymer yihariye ivanze ibi, ariko bigura byinshi. Nubucuruzi hagati yikiguzi cyambere no kubungabunga intera. Kubirindiro bifunze bitigeze bifungurwa, ukeneye hafi-zeru. Kuburyo bwo kugenzura bugenzurwa buri mwaka, 25% byashizweho birashobora kwemerwa.

Gushakisha no Guhoraho: Umutwe-Wisi Umutwe

Aha niho ibitekerezo bihurira hasi. Urashobora kwerekana umurongo wa ASTM D2000 guhamagarwa umunsi wose, ariko niba uwaguhaye isoko-kuri-bistency yazimye, uri mubibazo. Mfite gasketi yo muri SKU imwe, nategetse amezi atandatu atandukanye, aho ibara na tackness byari bitandukanye cyane. Utanga isoko yarahiye formula imwe. Ahari umucuruzi wibikoresho byahindutse, birashoboka ko igihe cyo gukira cyahinduwe. Ukeneye utanga isoko hamwe na QC ikomeye, ntabwo ari sosiyete yubucuruzi gusa.

Kubijwi-byinshi, bisanzwe byihuta kandi bifunga kashe, imiterere ya geografiya ifite akamaro. Mu Bushinwa, Akarere ka Yongnian muri Handan ni ihuriro rinini ry’ibicuruzwa bisanzwe. Isosiyete ishingiye aho, nka Hamagara zitai yihuta ukora co., Ltd., mubusanzwe ifite uburyo bwo gutanga ibintu byuzuye kubifata hamwe nibice bifitanye isano. Aho biherereye hafi yinzira nini zo gutwara abantu (https://www.zitaifacens.com) ntabwo ari aho kugurisha gusa; bivuze ibikoresho bya reberi mbisi hamwe nibicuruzwa byarangiye neza. Kubwumushinga ukeneye guhuza ibikorwa bya bolts, gukaraba, hamwe no gukata Rubber impapuro, ayo masoko ahuriweho arashobora gukumira guhuza inzozi mbi.

Ariko dore icyitonderwa: kuba mubikorwa fatizo ntabwo ubwiza bwimodoka. Bisobanura ko ugomba kuba usobanutse neza. Mugihe ukorana nabahinguzi nkabo, ugomba gusaba gukira itariki yo gukiza, icyemezo cyisesengura ryakozwe na reberi, ndetse wenda nicyitegererezo gito cyo gupima kwibiza mbere yuko umusaruro wose urangira. Ubuhanga bwabo mubifata birashobora kuba inyongera niba basobanukiwe nimbaraga zifatika, ariko ubushobozi bwabo bwibanze ntibushobora kuba iterambere rya elastomer.

Isesengura Kunanirwa: Ibisohoka bikwigisha

Ibihe byinshi byuburezi biva kuri post-mortem. Kumeneka ntabwo ari ukumena gusa; imiterere yacyo ivuga inkuru. Uniform kurira kuri flange yose? Birashoboka guhuzagurika bidahagije cyangwa ibintu byinshi bidahuye. Kumeneka kuri quadrant imwe? Birashoboka ko bolt itaringaniye cyangwa flange warpage. Kumeneka kugaragara gusa nyuma yo gusiganwa ku magare? Kwerekana mu buryo butaziguye kwaguka k'ubushyuhe budahuye cyangwa gukabya gukabije.

Nakoraga ku nzu ya pompe aho yamenekaga rimwe na rimwe. Byabaye gusa mugitangira. Twasimbuye gasketi inshuro ebyiri hamwe na spec imwe. Hanyuma, dushyira igipimo cyumuvuduko kumyobo ya bolt. Byagaragaye ko igishushanyo mbonera cyamazu cyateje flange nkeya hejuru yumuvuduko wimbere. Uwiteka Rubber ntishobora gukira vuba bihagije muriki gikorwa cyingirakamaro. Igisubizo cyari gasketi ifite modulus irenze urugero hamwe na durometero nkeya kugirango tunoze guhuza n'imitwaro ihindagurika. Urupapuro rwihariye ntirwigeze rukubwira ibyo.

Ikindi gihe, igitereko cyagaragaye kiribwa. Igitero cya shimi? Iyo usesenguye, mubyukuri byari imyambarire ikabije. Amazi anyura arimo ibintu byiza, kandi imivurungano yatumije gaze mugihe runaka. Ibikoresho bikomeye cyangwa uburyo butandukanye bwa gasketi hamwe nigishushanyo mbonera-cyari gikenewe. Byasaga nkibinaniranye byimiti ariko byari imashini. Buri gihe ubone icyitegererezo cyananiwe kandi rwose urebe.

Kurenga Impeta isanzwe: Igihe cyo Kubona Custom

Amabati apfa gukata hamwe nibisanzwe AS568 O-impeta ikubiyemo 80% yibikenewe. Ariko 20% isigaye itera 80% yumutwe. Aha niho ibicuruzwa byabugenewe cyangwa gukata umusarani biba ngombwa. Imiterere igoye, iminwa ihuriweho hamwe, cyangwa ibintu byinshi bifatika (nka kashe ya reberi ihujwe nicyuma).

Imbarutso yimirimo yihariye ntabwo ari imiterere idasanzwe. Ni mugihe ibice bisanzwe bidashobora kuzuza compression, extrusion, cyangwa ibisabwa mubuzima. Kurugero, igifuniko kinini, kidasanzwe kuri tank. Igipapuro cyaciwe ku rupapuro kizaba gifatanye-ahantu hashobora gutemba. Gukomeza kubumba cyangwa umusarani wacishijwe bugufi bikuraho ibyo. Igikoresho cyo gukoresha ni kinini, ariko kubisabwa bikomeye, bifite ishingiro. Icyemezo matrix kirimo ingano, kunegura, nigiciro cyose cyo gutsindwa.

Gukorana nu ruganda nka Handan Zitai Fastener yavuzwe, wakoresha ubuhanga bwabo bwihuse kubijyanye no gushushanya ariko ukenera kwemeza ubushobozi bwabo bwo gutunganya reberi - cyangwa abafatanyabikorwa babo basuzumye - bashobora gukora igice cya elastomer. Kwishyira hamwe ni urufunguzo. Kohereza igishushanyo cyabugenewe kububiko bwa reberi hamwe na bolt yerekanwe kumaduka yihuta, kandi twizeye ko bizahuza, ni uburyo bwo gutunga urutoki mugihe havutse ibibazo. Utanga isoko ashobora kugenzura cyangwa gutanga byombi azana kubazwa ibyingenzi.

Rero, irazenguruka inyuma. A. Rubber ntabwo ari igice gusa. Nuburyo bwa sisitemu isobanurwa na chimie yibikoresho, igishushanyo mbonera, gukora bihoraho, no kwishyiriraho ibikorwa. Icyerekezo nintangiriro yikiganiro, ntabwo iherezo. Wiga kubaha gasketi iciye bugufi, kuko iyo wirengagije imiterere yacyo, iba ifite uburyo butaziguye bwo kukwibutsa akamaro kayo.
