Sarudzo dzakasimba pano dzinosanganisira kushandisa zvakadzokororwa rabha zvemukati kana bio-sourced mapolymer. Kubata? Miganho yavo yemakemikari uye tembiricha yakaoma. EPDM yakasvibira inogona kunge yakanakira mvura inonwiwa asi inoshanduka kuita goo mumutsara weoiri. Iwe unofanirwa kuenzanisa midhiya zvakakwana.

Iyo Kuisa & Maintenance Wild Card

Hechino chokwadi chinowanzoshaikwa mumadheti ezvinyorwa: izvo zvakatsiga zvinhu zvinogona kuitirwa kutambisa nekusaisa zvakanaka. Kuwedzeredza-kurovera mabhaudhi kupwanya gasket mukuzviisa pasi? Izvo zvinosimbisa flange, kazhinji zvinokuvadza chimiro chemukati chegasket, uye inovimbisa hupenyu hupfupi. Under-torquing? Inobuda kubva pazuva rekutanga. Iyo inogoneka tsika ndeye chaiyo, yakaribrated kuisirwa ichitevera maitiro akakodzera seASME PCC-1. Ini ndanga ndiri panzvimbo dzavaishandisa yakachipa, yakakodzera gasket asi yakabaya iyo yekumisikidza ine mhedzisiro wrenches, zvichitungamira mukudonha pakutanga uye kuvharika kuzere kudzoreredza gasket. Kuraswa kwevashandi, nguva yekudzikira, uye ikozvino-yakaraswa gasket zvakapfuura zvakanyanya mutengo wechinhu cheprimiyamu chakaiswa nemazvo.

Saizvozvowo, uzivi hwekuchengetedza hunokosha. Iyo gasket inobatwa sechinhu chimwe-chekushandisa, chekurasa-kure, kana iyo sisitimu yakagadzirirwa kunyatso disassembly uye inogona kushandiswa zvakare (kune mamwe marudzi anogona kushandiswazve semamwe simbi ane jaketi gaskets)? Mune ichangoburwa retrofit yemutengi, isu takachinja kubva kuchekwa sheet CNA kuenda kune spiral ronda gasket ine graphite filler. Mutengo wekutanga waive wakakwira, asi panguva yekuchinja kwakarongwa, kazhinji vaigona kungodzokororazve gasket iripo kana ikaongororwa ikawana ruzha. Izvozvo zvakaponesa zvinhu uye basa.

Apa ndipo pave nemupi anovimbika anonzwisisa application yese, kwete kungotengesa pepa, kwakakosha. Shamwari yakadai Handan Zitai Fastener Kugadzira Co, Ltd. (https://www.zitafornasteers.com), yakavakirwa muChina's main fastener production hub, inowana izvi. Havasi chete gasket mutengesi; vari mukati memoyo weindasitiri yezvipenyu.

Paunokurukura purojekiti nemugadziri akadaro, iwe uri kupinda mune iyo inoshanda, yepasi-chikamu ruzivo nezve izvo chaizvo zvakamira mumunda, izvo zvinozivisa zvakananga sarudzo dzakasimba.

Case in Point: A Hot Oil System Retrofit

Rega ndifambe nebasa chairo. Chirimwa chaive nekudonha kusingaperi pane 300 ° C inopisa kutenderera kwemafuta. Vaishandisa standard aramid sheet gasket. Yakashanda pamwe 8-12 mwedzi isati yaoma uye kuchema. Ma drip aigara ari njodzi yemoto uye marara ane mafuta, pamwe nekutsiva nguva yaidhura.

Takazviongorora. Tembiricha yaive pamuganho wepamusoro webhainda mune iyo CNA zvinhu. Isu takakurudzira sarudzo mbiri: premium, yakakwirira-tembiricha CNA ine yakagadzikana resin system, kana yakawedzera graphite gasket. Iyo graphite yaive nemutengo wepamusoro wepamberi. Isu takamhanya nhamba: kuisa mukati mehupenyu hwebasa hunotarisirwa (graphite inofungidzirwa makore 3-5 vs. 1 gore rekutanga CNA), njodzi yakaderedzwa yekuvhara kusina kurongwa, uye kushandiswa kwekuchenesa (hapana binder kubheka kunze), girafu ndiyo yakave yakagadzikana uye ine hupfumi sarudzo pamusoro pemakore mashanu.

The kicker? Kuiswa. Taifanira kudzidzisa vashandi vavo vanogadzirisa kubata mapepa egraphite akapfava. Hapana kucheka paflange, kunyatsogadzirisa kurongeka, uye chaiyo, yakawanda-pass bolt inosimbisa kutevedzana. Zvakatora nguva yakawanda pakugadzwa kwekutanga. Asi zvakaramba. Makore matatu gare gare pakuongororwa kwakarongwa, ma gaskets aive achiri mune spec. Ndiko kugadzikana kwaunogona kuyera: zero inodonha, zero kutsiva, zero tsvina inogadzirwa kubva kune iyo system mumakore matatu.
