Kuyedzwa kweHydrostatic, inozivikanwawo se hydro test, ndiyo nzira yekuyedza magasi egasi kusimba uye kuvuza.Muedzo uyu unoitwa pamhando zhinji dzemasilinda akaita seokisijeni, argon, nitrogen, hydrogen, kabhoni dhaibhoni, magasi ekugadzirisa, musanganiswa wegasi, uye masilinda asina musono kana akaiswa simbi zvisinei nekuti humburumbira.Periodic hydro test inosimbisa kuti silinda iri mumamiriro ekushanda akakodzera uye akakodzera kuenderera mberi kushandiswa kwenguva yakatarwa.
Kuongororwa kweHydro yemasilinda kunosungirwa zvichienderana negwara kubva kuPetroleum uye Explosives Safety Organisation (PESO).High-pressure seamless cylinders inofanirwa kuongororwa nguva nenguva pamakore mashanu ega ega kana sezvinodiwa zvichienderana nemamiriro ecylinder.Mamwe magasi egasi senge CNG uye magasi ane muchetura anoda kuwanda kuongororwa, senge makore maviri ega ega.
Munguva yekuedzwa kwehydro, silinda inomanikidzwa kune bvunzo kumanikidza, kazhinji 1.5 kana 1.66 nguva yekushanda.Izvi zvinotarisa elasticity yezvinhu, izvo zvinodzikira nekufamba kwenguva nekudzokororwa kwekuzadza kutenderera.Iyo cylinder inomanikidzwa uye inodzvinyirirwa kuti ive nechokwadi chekuti inodzokera kune yayo yekutanga zviyero mukati meiyo yakatarwa kushivirira miganhu.Periodic hydro yekuongorora inosimbisa iyo silinda zvinhu zvichiri neyakakwana elasticity yekuchengetedzeka kuenderera kushandiswa.
Iyo hydro test maitiro inosanganisira kuzadza silinda neisinga tsikike mvura, kazhinji mvura, uye kuiongorora kuti inodonha kana shanduko yekusingaperi muchimiro.Mvura inowanzoshandiswa sezvo inenge isingagadziki uye inongowedzera nehuwandu hushoma.Kana gasi remhepo yakakwira raishandiswa, gasi raigona kuwedzera kusvika mazana akati wandei vhoriyamu yaro yakadzvanywa, ichimhanyisa njodzi yekukuvara kwakanyanya.Dzvinyiriro yebvunzo inogara yakawandisa kupfuura kumanikidza kwekushandisa kupa margin kune kuchengeteka.Kazhinji, 150% yesimba rekushanda rinoshandiswa.
Silinda inoiswa mukati mejasi remvura rine vhoriyamu inozivikanwa.Iyo jekete yemvura yakabatana necalibrated burette inoyera shanduko yehuwandu hwemvura mukati mejaketi.Humburumbira yacho inobva yamanikidzwa nemvura kusvikira yasvika pakuedza.Dzvinyiriro inobatwa kwenguva yakati, kazhinji masekonzi makumi matatu kana kupfuura.Munguva iyi, silinda inowedzera zvishoma uye inobvisa imwe mvura kubva mujasi kuenda kune freette.Kuwanda kwemvura yakadzingwa kunoratidza kuwedzera kwecylinder pasi pekumanikidzwa.Mushure mekubata nguva, kumanikidzwa kunosunungurwa uye cylinder inobvumirana nekukura kwayo kwepakutanga.Mvura yakabviswa inodzokera kubhachi kubva muburette.Kusiyana pakati pekutanga uye kwekupedzisira kuverenga kweburette kunoratidza kuwedzera kwekusingaperi kwe cylinder.
Kuwedzera kwechigarire hakufanirwe kudarika 10% yekuwedzera kwese.Kana ikadaro, zvinoreva kuti humburumbira yarasa kumwe kusimba kwayo uye inogona kunge yakatsemuka kana zvikanganiso zvinokanganisa kuvimbika kwayo.Masilinda akadaro anofanira kubviswa kubva kubasa uye kuparadzwa.Iyo hydro bvunzo zvakare inotarisa kudonha nekuona chero kudonha kwekumanikidza panguva yekubata kana chero mabhuru ari kubuda kubva pasirinda.
Iyo hydro test mhinduro inorekodhwa uye yakadhindwa pahumburumbira pamwe chete nezuva rekuyedzwa uye nhamba yekuzivikanwa yenzvimbo yekuyedza yakatenderwa.Iyo DOT inoda kuti hydrostatic retesting uye re-qualification iitwe nevamiriri vakanyoreswa vakapihwa certification neDOT uye vakapihwa inoshanda Re-testers Identification Number (RIN) neDOT Research uye Special Programs Administration (RSPA).Kuongororwa kweHydro kunovimbisa kuti masilinda egasi akachengeteka uye akavimbika pakushandisa kwawo.
