Iigaskethi ezikhethekileyo: Ziyintoni kwaye sizisebenzisa nini?

Iigaskethi ezikhethekileyo: Ziyintoni kwaye sizisebenzisa nini?

Ngaphezulu kweminyaka engama-500, amalunga ombhobho wentsimbi aqhagamshelwe ngeendlela ezahlukeneyo. Ukusuka kumalungu okuqala esisangqa aphuhliswayo ngo-1785 asebenzisa iigaskethi ezenziwe ngezinto ezahlukeneyo ekuvusweni kwentsimbi kunye nokudityaniswa kwe-spigot malunga ne-1950 eyayisebenzisa umsonto we-caulking okanye i-hemp eboshiweyo.

Iibhaskethi zanamhlanje zokutyhala zenziwa ziindidi ezahlukeneyo zeekhompawundi zerabha, kwaye ukuphuculwa kwe-gasket yokutyhala kuye kwangqineka kuluncedo ekuphumeleleni kwendawo engenamanzi evuzayo kunye nogutyulo lwelindle. Makhe sijonge ngakumbi kwi-gasket ekhethekileyo ekhoyo kwintengiso namhlanje.

Umsebenzi okhethekileyo ubize iiGasket ezikhethekileyo

Ngaba uyazi ukuba ayizizo zonke i-gaskets ezityhalelweyo ezenzelwe zonke izicelo? Ukuze wandise ukusebenza nangasiphi na isicelo, kubalulekile ukusebenzisa izixhobo ezifanelekileyo zegasket kwisicelo sakho esikhethekileyo.

Iimeko zomhlaba, ezinye iintlobo zemibhobho kufutshane nendawo okufaka kuyo, kunye nobushushu bamanzi zizinto eziphambili xa kusenziwa isigqibo sokuba yeyiphi i-gasket ekhethekileyo efanele umsebenzi. Iigaskethi ezikhethekileyo zenziwe ngeentlobo ezahlukeneyo zeelastomers zokuchasa nantoni na enokufunwa ngumsebenzi.

Uyikhetha njani i-Gasket ekhethekileyo yoMsebenzi?

Okokuqala, qiniseka ukusebenzisa iigaskethi ezikhethekileyo ezinikezwe ngumenzi wombhobho. Ukongeza, qiniseka ukuba iigaskethi ziyi-NSF61 kwaye i-NSF372 yamkelwe. Ngoku, masiqwalasele ngokuthe gca kwiibhasikithi ezahlukeneyo ezikhoyo, umahluko wabo, kunye nokusetyenziswa kwabo.

I-SBR (Styrene Butadiene)

I-Styrene Butadiene (SBR) gaskets zezona zisetyenziswa ngokuxhaphakileyo kwi-gasket ngokudibeneyo kwishishini le-Ductile iron pipe (DI pipe). Zonke iziqwenga zemibhobho ye-DI zithunyelwa ngomgangatho kunye ne-SBR gasket. I-SBR yeyona ndawo ikufutshane kwirabha yendalo yazo zonke iigasketi ezikhethekileyo.

Ukusetyenziswa okuqhelekileyo kwegasket ye-SBR zezi:

Amanzi osela; Amanzi oLwandle; Ukucoceka kwamanzi acocekileyo; Amanzi afunwayo; Amanzi aluhlaza; Amanzi esitshi

Obona bushushu benkonzo buninzi be-SBR tyhala i-gaskets edibeneyo yi-150 degrees Fahrenheit yezicelo zamanzi kunye nogutyulo.

I-EPDM (i-Ethylene Propylene Diene Monomer)

Iibhasikithi ze-EPDM zihlala zisetyenziswa ngombhobho we-Ductile Iron xa kukho ubukho be:

Utywala; Nciphisa ii-Acids; Nciphisa iAlkalis; IiKetone (MEK, Acetone); Iioyile zoLimo

Ezinye iinkonzo ezamkelekileyo zibandakanyiwe zezi:

Amanzi osela; Amanzi oLwandle; Ukucoceka kwamanzi acocekileyo; Amanzi afunwayo; Amanzi aluhlaza; Amanzi esitshi

I-EPDM ityhala i-gaskets edibeneyo inelinye lawona maqondo aphezulu obushushu enkonzo kwi-gaskets ezikhethekileyo ezintlanu kwi-212 degrees Fahrenheit yokufaka amanzi kunye nogutyulo.

Zilahlwe (NBR) (Acrylonitrile Butadiene)

Iibhaskithi zeNitrile zihlala zisetyenziswa ngombhobho wentsimbi yeDuctile xa kukho ubukho be:

IiHydrocarbon; Amafutha; Oyile; Ulwelo; Ukucocwa kwePetroleum

Ezinye iinkonzo ezamkelekileyo zibandakanya:

Amanzi osela; Amanzi oLwandle; Ukucoceka kwamanzi acocekileyo; Amanzi afunwayo; Amanzi aluhlaza; Amanzi esitshi

Zilahlwe tyhala gaskets ngokudibeneyo ukuba inkonzo ubuninzi lobushushu degrees 150 Fahrenheit amanzi kunye nokuhambisa amanzi amdaka.

I-Neoprene (CR) (iPolychloroprene)

Iibhasikithi ze-Neoprene zihlala zisetyenziswa kumbhobho wentsimbi ye-Ductile xa ujongene nenkunkuma enamafutha. Ukusetyenziswa kwabo kubandakanya:

Amanzi osela; Amanzi oLwandle; Ukucoceka kwamanzi acocekileyo; Amanzi afunwayo; Amanzi aluhlaza; Amanzi esitshi; IVithon, iFluorel (FKM) (IFluorocarbon)

Ezi zithathwa njenge- "Mack Daddy" yee-gaskets ezikhethekileyo- Viton gaskets can be used for:

IiHydrocarbon ezinamakha; Izinto ezibaselayo ii-Acids; Iioyile zoLimo; Iimveliso zePetroleum; IiHydrocarbon zeChlorinated; Uninzi lweKhemikhali kunye neeSolvents

Ezinye iinkonzo ezamkelekileyo zibandakanya:

Amanzi osela; Amanzi oLwandle; Ukucoceka kwamanzi acocekileyo; Amanzi afunwayo; Amanzi aluhlaza; Amanzi esitshi

Ukongeza, i-Viton push-on gaskets edibeneyo ineyona ndawo ineqondo lobushushu eliphezulu le-212 degrees Fahrenheit, isenza iVitamin gasket yeyona ibalaseleyo kunye nayo yonke-ejikeleze i-gasket ekhethekileyo ye-Ductile iron pipe. Kodwa eyona nto ibalaseleyo iza nendleko; Le yeyona gasket ibiza kakhulu kwimarike.

Ukunyamekela iiGaskethi zakho eziKhethekileyo

Ngoku, xa iigaskethi zakho zisiwe kwindawo yomsebenzi, qiniseka ukuba uyikhathalele kakuhle imali yakho oyityalayo. Izinto ezininzi zinokwenzakalisa ukusebenza kweefaskethi zakho.

Imiba emibi enjalo ibandakanya, kodwa ayikhawulelwanga:

Ukukhanya kwelanga ngokuthe ngqo; Ubushushu; Imozulu; Ukungcola; Imvuthuluka

Ubomi obulindelweyo bombhobho we-DI ungaphezulu kweminyaka eli-100, kwaye ngoku ukuba uyakwazi ukuchonga i-gasket ekhethekileyo kuyo nayiphi na imeko yendawo yomsebenzi, unokuqiniseka ukuba iprojekthi yakho yi-Iron Strong ekuhambeni kwexesha.
