Mavharuvhumidziyo yakakosha mukugadzirwa kwemaindasitiri, uye kuita kwavo kunokanganisa zvakananga kugadzikana uye kugona kwemaitiro ekugadzira. Regularvharafukuedza kunogona kuwana uye kugadzirisa matambudziko evhavha munguva, chengetedza kushanda kwakajairika kweiyovharafu, uye kuvandudza kushanda kwekugadzira.
Kutanga, kukosha kwekuongorora kushanda kwevhavha
1. Ita shuwa kuchengeteka uye kuvimbika:Mavharuvhuzvinhu zvakakosha zvinodzora mumapaipi emvura uye gasi, uye kuita mabasa akakosha mukudzora kuyerera kwemvura, kudzvanywa uye gwara. Pamusana pesimba rezvinhu zvakadai sekugadzira nzira, zvinhu uye magadzirirwo, kune dzimwe njodzi mukushandiswa kwemavharuvhu, zvakadai sekuvhara chisimbiso, simba risina kukwana, kusagadzikana kwekuora, nezvimwewo Kuburikidza nekuongorora kwekushanda, inogona kuvimbiswa kuti valve. inogona kumirisana nezvinodiwa zvekumanikidza mumutsetse wemvura, uye kudzivirira kuvuza, kusvibiswa, tsaona uye mamwe matambudziko anokonzerwa nekusaisa chisimbiso, kuitira kuti uve nechokwadi chekuchengetedza uye kwakavimbika kushanda kwehurongwa.
2. Kuvandudza unhu hwechigadzirwa uye kukwikwidzana kwemusika: Kuomerwa kwemaitiro ekuongorora maitiro ndiwo hwaro hwekuona kunaka kwezvigadzirwa zvevhavhavha yeindasitiri. Kuburikidza nenhevedzano yemaitiro ekuyedza, matambudziko anogona kuwanikwa anogona kuwanikwa nekugadziriswa, uye kukwikwidza kwemusika kwezvigadzirwa kunogona kuvandudzwa. Mayero epamusoro ekuyedzwa anovimbisawo kutivharafuinosangana nemhando dzakasiyana-siyana dzinoda kushanda kwemamiriro ezvinhu, zvakadai sekudzvinyirira simba munzvimbo dzakakwirira-dzinomanikidza, kuisa chisimbiso muhurumende yakavharwa, uye kuchinja uye kutendeseka.
3. Kuchengetedza kuchengetedza uye hupenyu hwebasa rakawedzerwa: kuongororwa kwekushanda kunogona kuongorora hupenyu hwebasa uye kuvimbika kwevhavhavha, kufanotaura hupenyu hwayo uye kukundikana kwehuwandu mukugadzirisa basa, uye kupa chirevo chekugadzirisa. Nenguva dzose yekuongorora uye kugadzirisa, unogona kuwedzera hupenyu hwevhavha yako uye kuderedza kukanganiswa kwekugadzira uye kugadzirisa mari nekuda kwekukundikana kwevhavha.
4. Tevedzera zviyero uye zvinotarisirwa zvinodiwa: Valve performance test inofanirwa kuenderana nemitemo yepasirese neyemumba kuti ive nechokwadi chekuti zvigadzirwa zvinosangana nekuchengetedza uye kunaka zvinodiwa. Kutevedzera chiyero hakungobatsiri chigadzirwa kuti chisimbiswe, asi zvakare kuwana kuvimba kwakanyanya uye kuzivikanwa mumusika.
Chechipiri, iyo performance test yemukati yevharafu
1. Chitarisiko uye logo yekuongorora
(1) Inspection content: kana pane kukanganisa pakuonekwa kwevhavha, zvakadai sekutsemuka, mabhuru, dents, nezvimwewo; Tarisa kuti logos, nameplates, uye kupedza zvinosangana nezvinodiwa. (2) Mitemo: Mitemo yepasi rose inosanganisira API598, ASMEB16.34, ISO 5208, nezvimwewo; Miyero yeChinese inosanganisira GB/T 12224 (zvakawanda zvinodiwa zvemavharuvhu esimbi), GB/T 12237 (simbi bhora mavharuvhu e petroleum, petrochemical uye maindasitiri ane hukama), nezvimwewo (3) Nzira yekuyedza: kuburikidza nekutarisa kwekuona uye kutariswa kwemaoko, kuona kana pane zvikanganiso zviri pachena pamusoro pevhavha, uye tarisa kana iyo yekuzivikanwa uye nameplate ruzivo rwakarurama.
2. Dimensional kuyerwa
(1) Ongororo yemukati: Edza zviyero zvakakosha zvevhavha, kusanganisira chiteshi chekubatanidza, kureba kwemuviri wevharuvhu, dhayamita yehunde yevharuvhu, nezvimwewo, kuve nechokwadi kuti inosangana nezvinodiwa zvedhizaini yekudhirowa uye zviyero. (2) Mitemo: Mitemo yenyika yose inosanganisira ASMEB16.10, ASME B16.5, ISO 5752, nezvimwewo; Zviyero zveChinese zvinosanganisira GB/T 12221 (valve structure urefu), GB/T 9112 (flange connection size), etc. (3) Testing method: Shandisa macalipers, micrometers nezvimwe zvekuyeresa maturusi ekuyera zviyero zvakakosha zvevhavha kuti uone kuti inosangana nezvinodiwa zvekugadzira.
3. Kuisa chisimbiso bvunzo yekuita
(1) Static pressure test: shandisa hydrostatic pressure kana static pressure kuvhavha, uye tarisa kuvuza mushure mekuchengetedza kwenguva yakati. (2) Low-pressure air tightness test: Kana vheji yakavharwa, gasi rinopisa rinoshandiswa mukati mevhavha uye kubuda kunotariswa. (3) Muedzo wesimba reimba: shandisa hydrostatic pressure yakakwirira kudarika kushanda kwevhavha kuti uedze simba rayo reimba uye kusagadzikana kwekudzivirira. (4) Stem Strength Test: Ongorora kana torque kana tensile simba rinowanikwa ne stem panguva yekushanda iri mukati meyakachengeteka renji.
4. Operational performance test
(1) Kuvhura nekuvhara torque uye bvunzo yekumhanyisa: edza kuvhura nekuvhara torque, kuvhura nekuvhara kumhanya uye kushanda kwekunzwa kwevhavhavha kuti ive nechokwadi chekushanda kwakanaka uye mukati meiyo inonzwisisika torque renji. (2) Kuyerera kwehunhu bvunzo: edza kuyerera maitiro evhavha pane akasiyana mazaru kuti uongorore kugona kwayo kugadzirisa mvura.
5. Corrosion resistance test
(1) Ongororo yemukati: ongorora kushomeka kweiyo valve zvinhu kune inoshanda svikiro. (2) Mitemo: Mitemo yepasi rose inosanganisira ISO 9227 (munyu wekupfapfaidza bvunzo), ASTM G85, zvichingodaro. corrosive conditions.
6. Kugara uye kuvimbika bvunzo
(1) Kudzokororwa kuvhura uye kuvhara kutenderera bvunzo: Kudzokororwa kuvhurika nekuvhara kutenderera kunoitwa pavharuvhu kuti iongorore kusimba kwayo uye kuvimbika mukushandiswa kwenguva refu. (2) Tembiricha kugadzikana bvunzo: edza kugadzikana kwekuita kwevhavha pasi pemamiriro akasiyana ekushisa kuti ive nechokwadi chekushanda kwayo kwakajairika munzvimbo dzakanyanya tembiricha. (3) Vibration uye bvunzo yekuvhundutsa: Isa vharafu patafura inodedera kana tafura yekukanganisa kutevedzera kuzununguka uye kuvhunduka munzvimbo yekushanda uye kuyedza kugadzikana uye kuvimbika kwevhavha.
7. Kuonekwa kwemvura
(1) Yemukati inovuza yekuona: edza iyo yemukati yekuisa chisimbiso kuita kwevharafumunzvimbo yakavharwa. (2) Kuonekwa kwekubuda kwekunze: tarisa kusimba kwekunze kweiyovharafuiri kushandiswa kuona kuti hapana kupera kwepakati.
TWS Valve inonyanya kuburitsa yakasimba yakagarabutterfly valve, kusanganisira wafer type, lug type,kaviri flange concentric mhando, double flange eccentric type.
