IiGaskets ezikhethekileyo: Ziyintoni kwaye Sizisebenzisa nini?

IiGaskets ezikhethekileyo: Ziyintoni kwaye Sizisebenzisa nini?

Ngaphezu kweminyaka engama-500, imibhobho yentsimbi iye yadityaniswa ngeendlela ezahlukahlukeneyo.Ukusukela kumalungu okuqala aneflanged aphuhliswe ngo-1785 asebenzisa iigaskets ezenziwe ngezinto ezahlukeneyo ukuya kwi-bell kunye ne-spigot joint malunga no-1950 eyayisebenzisa i-caulking larn okanye i-hemp ephothiweyo.

Iigaskets zanamhlanje ezityhalayo zibandakanya iindidi ezahlukeneyo zeekhompawundi zerabha, kwaye uphuhliso lwe-push-on gasket lungqineke luluncedo kwimpumelelo yamanzi angavuziyo kunye nomdibaniso wogutyulo.Makhe sijonge ngakumbi kwi-gasket nganye ekhethekileyo ekhoyo kwimarike namhlanje.

ImiSebenzi ekhethekileyo ibiza iiGaskets eziKhethekileyo

Ngaba ubusazi ukuba ayizizo zonke iigaskets ezityhalayo ezenzelwe zonke izicelo?Ukuze ukwandise ukusebenza kakuhle kuso nasiphi na isicelo, kubalulekile ukusebenzisa imathiriyeli efanelekileyo yegasket kwisicelo sakho esikhethekileyo.

Iimeko zomhlaba, ezinye iintlobo zemibhobho ekufutshane nendawo yakho yofakelo, kunye nobushushu bolwelo zizinto eziphambili xa kumiselwa ukuba yeyiphi igasket ekhethekileyo elungele umsebenzi.Iigaskets ezikhethekileyo zenziwe ngeentlobo ezahlukeneyo zeelastomers ukumelana nayo nayiphi na into enokufunwa ngumsebenzi.

Ungayikhetha njani iGasket yeNgcaciso eLungileyo yoMsebenzi?

Okokuqala, qiniseka ukusebenzisa iigaskets ezikhethekileyo ezibonelelwa ngumenzi wombhobho.Ukongeza, qiniseka ukuba iigaskets zi-NSF61 kunye ne-NSF372 evunyiweyo.Ngoku, makhe sijonge ngakumbi kwiigaskets ezikhethekileyo ezikhoyo, ukungafani kwazo, kunye nokusetyenziswa kwazo.

I-SBR (iStyrene Butadiene)

I-Styrene Butadiene (SBR) gaskets zezona gasket ezixhaphakileyo zisetyenziswa ngokudibeneyo kumbhobho wentsimbi weDuctile (DI pipe) ishishini.Iqhekeza ngalinye lombhobho we-DI lithunyelwa ngokusemgangathweni kunye ne-SBR gasket.I-SBR yeyona ikufutshane kwirabha yendalo kuzo zonke iigaskets ezikhethekileyo.

Ukusetyenziswa okuqhelekileyo kwe-SBR gasket zezi:

Amanzi osela;Amanzi oLwandle;Umjelo ophantsi komhlaba ohambisa amanzi amdaka;Amanzi abuyiselweyo;Amanzi akrwada;Amanzi esitshi

Obona bushushu benkonzo buphezulu kwi-SBR push joint gaskets yi-150 degrees Fahrenheit kusetyenziso lwamanzi kunye nogutyulo.

EPDM (Ethylene Propylene Diene Monomer)

Iigaskets ze-EPDM ziqhele ukusetyenziswa kunye neDuctile Iron pipe xa kukho ubukho be:

Utywala;Dilute Acids;Nciphisa ialkali;I-Ketones (MEK, i-Acetone);IiOyile zemifuno

Ezinye iinkonzo ezamkelekileyo eziqukiweyo zezi:

Amanzi osela;Amanzi oLwandle;Umjelo ophantsi komhlaba ohambisa amanzi amdaka;Amanzi abuyiselweyo;Amanzi akrwada;Amanzi esitshi

I-EPDM push joint gaskets inelona qondo liphezulu lobushushu benkonzo yeegaskets ezintlanu eziphambili kwii-212 degrees Fahrenheit kusetyenziso lwamanzi kunye nogutyulo.

I-Nitrile (NBR) (Acrylonitrile Butadiene)

Iigaskiti zeNitrile ziqhele ukusetyenziswa kunye nombhobho wentsimbi weDuctile xa kukho ubukho be:

Iihydrocarbons;Amafutha;Ioyile;Ulwelo;I-Refined Petroleum

Ezinye iinkonzo ezamkelekileyo ziquka:

Amanzi osela;Amanzi oLwandle;Umjelo ophantsi komhlaba ohambisa amanzi amdaka;Amanzi abuyiselweyo;Amanzi akrwada;Amanzi esitshi

I-Nitrile ityhala iigaskets ezidityanisiweyo zobushushu benkonzo obuphezulu obuyi-150 degrees Fahrenheit kusetyenziso lwamanzi kunye nogutyulo.

Neoprene (CR) (Polychloroprene)

Iigasket zeNeoprene ziqhele ukusetyenziswa kunye neDuctile iron pipe xa ujongene nenkunkuma enamafutha.Ukusetyenziswa kwabo kubandakanya:

Amanzi osela;Amanzi oLwandle;Umjelo ophantsi komhlaba ohambisa amanzi amdaka;Amanzi abuyiselweyo;Amanzi akrwada;Amanzi esitshi;Viton, Fluorel (FKM) (Fluorocarbon)

Ezi zijongwa njengo "Mack Daddy" weegaskets ezikhethekileyo - iigaskets zeViton zinokusetyenziselwa:

IiHydrocarbons ezinuka kamnandi;Izibaso zeAcids;Ioli yemifuno;Iimveliso zePetroleum;IiHydrocarbons ezineklorini;Uninzi lwamachiza kunye nezinyibilikisi

Ezinye iinkonzo ezamkelekileyo ziquka:

Amanzi osela;Amanzi oLwandle;Umjelo ophantsi komhlaba ohambisa amanzi amdaka;Amanzi abuyiselweyo;Amanzi akrwada;Amanzi esitshi

Ukongeza, i-Viton push-on joint gaskets inobona bushushu benkonzo buphezulu obuyi-212 degrees Fahrenheit, isenza i-Viton gasket ibe yeyona gasket igqwesileyo iyonke kwaye ijikeleze igasket ekhethekileyo yombhobho wentsimbi weDuctile.Kodwa ukuba ngoyena ubalaseleyo kuza neendleko;le yeyona gasket ibiza kakhulu kwiimarike.

Ukukhathalela iiGaskets zakho eziZodwa

Ngoku, nje ukuba iigaskets zakho zisiwe kwindawo yomsebenzi, qiniseka ukuba unakekele ngokufanelekileyo utyalo-mali lwakho.Izinto ezininzi zinokulimaza ukusebenza ngokubanzi kweegaskets zakho.

Ezi zinto zingalunganga ziquka, kodwa aziphelelanga koku:

Ilanga elithe ngqo;Ubushushu;Imozulu;Ukungcola;Inkunkuma

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