Iwasha iyimpahla noma inhlanganisela yezinto eziboshelwe phakathi kwezixhumi ezimbili ezizimele (ikakhulukazi ama-flange), umsebenzi wazo uwukugcina uphawu phakathi kwezixhumi ezimbili ngesikhathi sempilo yesevisi enqunywe kusengaphambili. Iwasha kufanele ikwazi ukuvala indawo ehlangene futhi iqinisekise ukuthi i-seal medium ayingeneli futhi ayigqwalile, futhi ingamelana nemiphumela yokushisa nokucindezela.Amawasha ngokuvamile ahlanganisa izixhumi (njengama-flanges), amawasha, nezixhumi (ezifanaamabhawodifuthiamantongomane ). Ngakho-ke, lapho kunqunywa ukusebenza kokuvala kwe-flange ethile, sonke isakhiwo sokuxhuma kwe-flange kufanele sithathwe njengesistimu. Ukusebenza okuvamile noma ukwehluleka kwe-washer akuxhomekile kuphela ekusebenzeni kwe-washer eklanyelwe ngokwayo, kodwa futhi nokuqina nokuguqulwa kwesistimu, ukuqina nokuhambisana kwendawo ehlangene, nobukhulu nokufana komthwalo wokubopha.
Izinto Ezinhlanu Zokukhetha Shim:
1.izinga lokushisa:
Ngaphezu kwamazinga okushisa aphezulu kanye nobuncane bokusebenza obungabekezelelwa esikhathini esifushane, izinga lokushisa elivumelekile eliqhubekayo lokusebenza kufanele futhi licatshangelwe. Izinto zokuwasha kufanele zikwazi ukumelana nokukhasa ukuze kuncishiswe ukuphumuza ingcindezi kwewashi, ukuze kuqinisekiswe ukuvaleka kwayo ngaphansi kwezimo zokusebenza. Izinto eziningi zokuwasha zizobhekana nokukhuphuka okunzima njengoba izinga lokushisa likhuphuka. Ngakho-ke, inkomba ebalulekile yekhwalithi yewashi ukusebenza kokuphumula kwe-washer ekushiseni okuthile.
2.uhlelo lokusebenza:
Ibhekisela kakhulu olwazini lwesistimu yokuxhuma lapho iwasha itholakala khona, futhi impahla yewasha efanele kanye nohlobo kufanele kukhethwe ngokusekelwe kumpahla ye-flange, uhlobo lwendawo yokuvala ye-flange, ukuhlukumeza kwe-flange. i-flange , nolwazi lwebhawodi. Ama-Non metallic flanges kufanele akhethe ama-gaskets anezidingo zamandla okuqinisa kancane aphansi, ngaphandle kwalokho kungase kube nezimo lapho i-gasket ingakacindezelwa khona futhi i-flange iye yachotshozwa ngesikhathi senqubo yokuqinisa i-flange.
3.phakathi:
Iwasha akufanele ithintwe indawo yokuvala kuzo zonke izimo zokusebenza, okuhlanganisa ukumelana ne-oxidation ephezulu lokushisa, ukumelana nokugqwala kwamakhemikhali, ukumelana ne-solvent, ukumelana nokuqina, njll. Ngokusobala, ukumelana nokugqwala kwamakhemikhali kwe-gasket material kuya phakathi kuyisimo esiyinhloko. ukuze ukhethe iwasha.
4.ingcindezi:
Iwasha kufanele ikwazi ukumelana nokucindezela okukhulu, okungaba ukucindezela kokuhlola, okungase kube izikhathi ezingu-1.25 kuya kwezingu-1.5 zokucindezela okuvamile kokusebenza. Kuma-gaskets angewona awensimbi, ukucindezela kwawo okuphezulu kuhlobene nokushisa okuphezulu okusebenzayo. Ngokuvamile, inani lokushisa eliphakeme kakhulu eliphindwe ngokucindezela okukhulu (okungukuthi inani le-PxT) linenani elilinganiselwe. Ngakho-ke, lapho ukhetha umfutho wabo omkhulu wokusebenza, kuyadingeka futhi ukucabangela inani eliphakeme le-PxT elingamelana ne-gasket.
5.usayizi:
Kwabaningi abanga-ama-washer weshidi lensimbi , amawasha amancane nawo anekhono elikhulu lokumelana nokuphumula kokucindezeleka. Ngenxa yendawo encane yokuxhumana phakathi kohlangothi lwangaphakathi lwewasha elincanyana kanye nendawo ephakathi, ukuvuza eduze nomzimba wewasha nakho kuyancishiswa, futhi kulokhu, amandla aphephukayo athwalwa yiwasha nawo mancane, okwenza kube nzima iwasha izoshaywa umoya
