Zopangidwavalavus ayenera kuyesedwa kosiyanasiyana, chofunikira kwambiri ndikuyesa kuthamanga.Kuyesedwa kwapanikizi ndikuyesa ngati kupanikizika komwe valavu ingathe kupirira kumakwaniritsa zofunikira zamalamulo opanga.Mu TWS, ndivalavu yofewa ya butterfly, ayenera kunyamulidwa mkulu kuthamanga mpando kukanika mayeso.Kupanikizika komwe kumatchulidwa mu 1.5 nthawi za PN kudzagwiritsidwa ntchito pamadzi oyesera.
Mawu ofunika:Kuyesa kwa Pressure;Vavu Yofewa ya Gulugufe;Pressure Seat Tightness Test
Nthawi zambiri, kuthamanga mayeso amavavuayenera kutsatira mfundo ndi njira zotsatirazi:
(1) Nthawi zambiri, avalavusichiyesedwa mphamvu, komavalavuthupi ndi bonati pambuyo kukonza kapenavalavuthupi ndi boneti ndi kuwonongeka dzimbiri ayenera kuyesedwa mphamvu.Kwa valavu yotetezera, kupanikizika kwake kosalekeza, kukakamiza kubwezeretsanso ndi mayesero ena kudzatsatira ndondomeko ya malangizo ake ndi malamulo oyenera.
(2) Kuyesa kwamphamvu ndi kulimba kuyenera kuchitidwa pamaso pavalavuimayikidwa.20% ya ma valve otsika kwambiri amafufuzidwa, ndipo 100% ya iwo ayenera kufufuzidwa ngati ali oyenerera;100% ya ma valve apakati ndi apamwamba kwambiri ayenera kuyang'aniridwa.
(3) Pa mayeso, unsembe udindo wavalavukuyenera kukhala komwe kuyang'ana kumakhala kosavuta.
(4) Kwamavavumu mawonekedwe a welded malumikizidwe, ngati akhungu mbale kuthamanga mayeso sangathe ntchito, conical chisindikizo kapena O-mphete chisindikizo angagwiritsidwe ntchito kuyesa kuthamanga.(5) Osapatula mpweya wa valve momwe mungathere panthawi ya hydraulic test.
(6) Kupanikizika kuyenera kuwonjezeka pang'onopang'ono panthawi ya mayesero, ndipo kupanikizika koopsa komanso mwadzidzidzi sikuloledwa.
(7) Kutalika kwa mayeso a mphamvu ndi mtundu wosindikiza nthawi zambiri ndi mphindi 2-3, ndipo ma valve ofunikira komanso apadera ayenera kukhala kwa mphindi zisanu.Nthawi yoyesera ya mavavu aang'ono ang'onoang'ono ikhoza kukhala yayifupi mofanana, ndipo nthawi yoyesera ya mavavu akuluakulu ingakhale yotalikirapo.Panthawi yoyesedwa, ngati mukukayikira, nthawi yoyesera ikhoza kuwonjezereka.Panthawi yoyezetsa mphamvu, kutuluka thukuta kapena kutayikiravalavuthupi ndi boneti siziloledwa.Kuyesa kusindikiza kumangochitika kamodzi kokhamavavu, ndi kawiri kwa ma valve otetezera, kuthamanga kwambirimavavundi zina zofunikamavavu.Pakuyesedwa, kutayikira pang'ono kumaloledwa kwa ma valve osafunika omwe ali ndi mphamvu yochepa komanso yaikulu m'mimba mwake ndi ma valve omwe ali ndi malamulo kuti alole kutuluka;chifukwa cha zofunikira zosiyanasiyana za ma valve ambiri, ma valve opangira magetsi, ma valve a m'madzi ndi ma valve ena, zofunikira zowonongeka ziyenera kukhala motere: Kuchita mogwirizana ndi malamulo oyenerera.
(8) Valve ya throttle sichimayesedwa ndi kutsekedwa kwa gawo lotseka, koma kuyesa mphamvu ndi kuyesedwa kolimba kwa kunyamula ndi gasket ziyenera kuchitidwa.(9) Pakuyesa kukakamiza, mphamvu yotseka ya valve imaloledwa kutsekedwa ndi mphamvu yachibadwa ya munthu mmodzi;sikuloledwa kugwiritsa ntchito mphamvu ndi zida monga ma levers (kupatula wrench ya torque).Pamene m'mimba mwake wa handwheel ndi wamkulu kapena wofanana 320mm, anthu awiri amaloledwa ntchito pamodzi.kutseka.
(10) Kwa mavavu okhala ndi chosindikizira chapamwamba, kulongedzako kuyenera kutengedwa kukayesa kulimba.Chisindikizo chapamwamba chikatsekedwa, yang'anani ngati chikutuluka.Mukamagwiritsa ntchito gasi ngati mayeso, yang'anani ndi madzi mubokosi lodzaza.Mukayesa kunyamula katundu, chisindikizo chapamwamba sichiloledwa kukhala cholimba.
(11) Kwa valavu iliyonse yokhala ndi chipangizo choyendetsa galimoto, poyesa kulimba kwake, chipangizo choyendetsa galimoto chiyenera kugwiritsidwa ntchito kutseka valavu ndikuyesa kuyesa.Kwa chipangizo choyendetsedwa ndi manja, kuyesa kusindikiza kwa valve yotsekedwa pamanja kudzachitidwanso.
(12) Pambuyo pa kuyesedwa kwa mphamvu ndi kulimba, valve yodutsa yomwe imayikidwa pa valve yaikulu idzayesedwa kuti ikhale yamphamvu ndi yolimba pa valve yaikulu;pamene gawo lotseka la valavu lalikulu litsegulidwa, lidzatsegulidwanso molingana.
(13) Pakuyesa mphamvu kwa mavavu achitsulo choponyedwa, tambani thupi la valve ndi chivundikiro cha valve ndi belu lamkuwa kuti muwone ngati kutayikira.
(14) Pamene valavu iyesedwa, kupatulapo ma valve otsekemera omwe amalola kuti malo osindikizira apangidwe ndi mafuta, ma valve ena saloledwa kuyesa malo osindikizira ndi mafuta.
(15) Pakuyesa kukakamiza kwa valavu, kukakamiza kwa mbale yakhungu pa valavu sikuyenera kukhala kwakukulu, kuti musapewe kusinthika kwa valve ndi kukhudza zotsatira zoyesa (ngati valavu yachitsulo yachitsulo imakanizidwa mwamphamvu kwambiri. , zidzawonongeka).
(16) Pambuyo poyesa kupanikizika kwa valve kutsirizidwa, madzi osonkhanitsidwa mu valve ayenera kuchotsedwa nthawi ndi kupukuta, ndipo zolemba zoyesa ziyenera kupangidwanso.
In Chithunzi cha TWS, Pankhani yathu yayikulu, valavu yagulugufe yofewa yokhala pansi, iyenera kuchitidwa mayeso olimba kwambiri pampando.Ndipo sing'anga yoyesera ndi madzi kapena gasi, ndipo kutentha kwa sing'anga yoyesera kuli pakati pa 5℃~40℃.
Ndipo kuyesa kotsatiraku ndikulimba kwa chipolopolo ndi ma valve.
Cholinga chake ndi chakuti kuyesako kutsimikizire kutsetsereka kwa chipolopolocho kuphatikizapo makina ogwiritsira ntchito kusindikiza kupanikizika kwa mkati.
Panthawi yoyesera, tiyenera kuzindikira kuti madzi oyesera adzakhala madzi.
Ndipo diski ya valve idzakhala yotseguka pang'ono.Mapeto a valavu adzakhala atatsekedwa ndipo mabowo onse adzadzazidwa ndi madzi oyesera.Kupanikizika komwe kumatchulidwa mu 1.5 nthawi za PN kudzagwiritsidwa ntchito pamadzi oyesera.
