Kukonzekera kwa valve tsiku ndi tsiku
1. Vavu iyenera kusungidwa m'chipinda chowuma ndi mpweya wabwino, ndipo mapeto onse a ndimeyi ayenera kutsekedwa.
2. Mavavu omwe akhala akusungidwa kwa nthawi yayitali ayenera kuyang'anitsitsa nthawi zonse, dothi lichotsedwe, ndipo mafuta oletsa dzimbiri ayenera kugwiritsidwa ntchito pokonza.
3. Pambuyo pa kukhazikitsa, kufufuza nthawi zonse kuyenera kuchitidwa.Zinthu zazikulu zowunikira:
(1) Kuvala kwa malo osindikizira.
(2) Kuvala kwa ulusi wa trapezoidal wa tsinde ndi mtedza wa tsinde.
(3) Kaya kulongedza kwachikale komanso kosavomerezeka, ngati kwawonongeka, ziyenera kusinthidwa panthawi yake.
(4) Pambuyo pa SINGLE UNIONMPIRA VALVE X9201-TGREY imakonzedwanso ndikusonkhanitsidwa, kuyesa kosindikiza kumayenera kuchitidwa.
Ntchito yosamalira pa nthawi ya jekeseni wa valavu
Ntchito yokonza valavu isanayambe kuwotcherera komanso itatha kupangidwa imakhala yofunika kwambiri pakupanga ndi kugwira ntchito kwa valve.Kukonzekera koyenera, mwadongosolo komanso kothandiza kudzateteza valavu, kupanga valavu kugwira ntchito moyenera ndikutalikitsa moyo wautumiki wa valve.moyo.Ntchito yokonza ma valve ingaoneke ngati yosavuta, koma si choncho.Nthawi zambiri pamakhala mbali zina za ntchito zomwe zimanyalanyazidwa.
1. Pobaya mafuta mu valavu, kuchuluka kwa jekeseni wamafuta nthawi zambiri kumanyalanyazidwa.Pambuyo pa mfuti ya jekeseni wa mafuta, wogwira ntchitoyo amasankha valavu ndi njira yolumikizira jekeseni wamafuta, ndiyeno amachita ntchito yojambulira mafuta.Pali zinthu ziwiri: kumbali imodzi, kuchuluka kwa jekeseni wamafuta ndi kochepa ndipo jekeseni wamafuta ndi wosakwanira, ndipo malo osindikizira amavala mofulumira chifukwa cha kusowa kwa mafuta.Kumbali inayi, jekeseni wochuluka wamafuta umabweretsa kutaya.Chifukwa chake ndi chakuti palibe kuwerengera kwa mphamvu zosiyanasiyana zosindikizira ma valve malinga ndi gulu la mtundu wa valve.Mphamvu yosindikiza imatha kuwerengedwa molingana ndi kukula kwa valavu ndi mtundu, ndiyeno mafuta okwanira amatha kubayidwa.
2. Vavu ikapaka mafuta, vuto la kupanikizika nthawi zambiri limanyalanyazidwa.Pa ntchito ya jekeseni mafuta, kuthamanga kwa jekeseni wa mafuta kumasintha nthawi zonse ndi nsonga ndi zigwa.Kupsyinjika ndikotsika kwambiri, chisindikizo chimatuluka kapena kulephera, kupanikizika kwapamwamba kwambiri, khomo la jekeseni wamafuta ndilotsekedwa, mafuta osindikizira amkati amawumitsidwa, kapena mphete yosindikizira imatsekedwa ndi mpira wa valve ndi mbale ya valve.Nthawi zambiri, mphamvu ya jakisoni wa girisi ikatsika kwambiri, mafuta omwe amabayidwa nthawi zambiri amalowa pansi pa valve, yomwe nthawi zambiri imapezeka m'mavavu ang'onoang'ono.Ngati mphamvu ya jakisoni wa girisi ndiyokwera kwambiri, mbali imodzi, yang'anani pobowolo ya girisi, ndikusintha ngati bowo latsekeka..Kuphatikiza apo, mtundu wosindikiza ndi zinthu zosindikizira zimakhudzanso kuthamanga kwa jekeseni wamafuta.Mitundu yosiyanasiyana yosindikiza imakhala ndi mphamvu zosiyanasiyana za jakisoni wamafuta.Nthawi zambiri, kukakamiza kwa jekeseni wamafuta osindikizira kumayenera kukhala chisindikizo chofewa kwambiri.
3. Mukalowetsa mafuta mu valavu, tcherani khutu ku vuto lomwe valve ili mu malo osinthira.Valve ya mpira nthawi zambiri imakhala yotseguka panthawi yokonza, ndipo mwapadera, imasankhidwa kuti itsekedwe kuti ikonzedwe.Ma valve ena sangathe kuonedwa ngati malo otseguka.Valavu yachipata iyenera kutsekedwa panthawi yokonza kuti mafuta adzaza ndi phula losindikizira pambali pa mphete yosindikizira.Ngati itatsegulidwa, mafuta osindikizira amagwera mwachindunji mumtsinje wothamanga kapena valve, zomwe zimapangitsa kuti ziwonongeke.
Chachinayi, valavu ikapaka mafuta, zotsatira za jekeseni wamafuta nthawi zambiri zimanyalanyazidwa.Panthawi yobaya mafuta, kukakamiza, kuchuluka kwa jakisoni wamafuta, ndi malo osinthira zonse ndizabwinobwino.Komabe, pofuna kuonetsetsa kuti jekeseni wa mafuta a valve, nthawi zina ndikofunikira kutsegula kapena kutseka valavu, kuyang'ana momwe mafuta amathandizira, ndikutsimikizira kuti pamwamba pa mpira wa valve kapena mbale ya pachipata ndi yofanana.
5. Mukamabaya mafuta, tcherani khutu ku vuto la valavu yamadzimadzi ndi mawaya plugging pressure.Pambuyo poyesa kukakamiza valavu, mpweya ndi madzi muzitsulo za valve zotsekera zidzakulitsidwa chifukwa cha kuwonjezeka kwa kutentha kozungulira.Mafuta akamabayidwa, m'pofunika kutulutsa zimbudzi ndi kumasula kupanikizika, kuti athe kupititsa patsogolo jekeseni wamafuta.Mpweya ndi chinyezi m'bowo lotsekedwa zimasinthidwa kwathunthu pambuyo pa jekeseni wamafuta.Kuthamanga kwa valve cavity kumatulutsidwa mu nthawi, zomwe zimatsimikiziranso chitetezo cha valve.Pambuyo pa jekeseni wamafuta, onetsetsani kuti mwamangitsa kukhetsa ndi mapulagi opumira kuti mupewe ngozi.
6. Pobaya mafuta, samalani ndi vuto la yunifolomu.Pa jekeseni wamba wamafuta, bowo lotulutsa mafuta lomwe lili pafupi kwambiri ndi doko lojambulira mafuta limatulutsa mafuta poyamba, kenako mpaka pansi, kenako mpaka pamtunda, ndipo mafutawo amatulutsidwa mmodzimmodzi.Ngati sichitsatira malamulo kapena palibe mafuta, zimatsimikizira kuti pali chotchinga, ndipo chiyenera kutsukidwa nthawi.
7. Mukamabaya mafuta, onaninso kuti m'mimba mwake valavu ndi chopukutira ndi mpando mphete yosindikiza.Mwachitsanzo, kwa valavu ya mpira, ngati pali kusokoneza pamalo otsegulira, sinthani malo otsegulira mkati kuti mutsimikizire kuti m'mimba mwake ndi yowongoka ndikutseka.Kusintha malire sikuyenera kungotsatira malo otsegulira kapena otseka, koma ganizirani zonse.Ngati malo otsegulira akuthamanga ndipo malo otsekera salipo, valve sidzatseka mwamphamvu.Momwemonso, ngati kusintha kwa malo otsekedwa kuli koyenera, kusintha kofanana kwa malo otseguka kuyeneranso kuganiziridwa.Onetsetsani kuti valavu ili ndi ngodya yoyenera yoyenda.
8. Mukatha jekeseni wamafuta, onetsetsani kuti mwasindikiza doko la jakisoni wamafuta.Pofuna kupewa kulowa kwa zonyansa, kapena kutsekemera kwa lipids pa doko la jakisoni wamafuta, chivundikirocho chiyenera kuphimbidwa ndi mafuta oletsa dzimbiri kuti asachite dzimbiri.kwa opareshoni yotsatira.
9. Pobaya mafuta, kuganiziranso kuyenera kuganiziridwa pa chithandizo chapadera cha zovuta zenizeni mumayendedwe otsatizana amafuta m'tsogolomu.Poganizira zamitundu yosiyanasiyana ya dizilo ndi petulo, kuthekera kowonongeka ndi kuwonongeka kwa mafuta kuyenera kuganiziridwa.M'ntchito yamtsogolo ya valve, mukakumana ndi gawo la mafuta, mafutawo ayenera kuwonjezeredwa panthawi yake kuti asawonongeke.
10. Mukamabaya mafuta, musanyalanyaze jekeseni wamafuta pa tsinde la valve.Pali zitsulo zotsetsereka kapena zonyamula pa shaft ya valve, zomwe zimafunikanso kusungidwa kuti zikhale ndi mafuta kuti zichepetse kusagwirizana pakati pa ntchito.Ngati kutsekemera sikungatsimikizidwe, torque imawonjezera magawo ovala panthawi yamagetsi, ndipo chosinthiracho chimakhala chovutirapo pakugwira ntchito pamanja.
11. Ma valve ena a mpira amalembedwa ndi mivi.Ngati palibe cholembera cha Chingerezi cha FIOW, ndiye chitsogozo cha mpando wosindikizira, osati monga kufotokozera kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka valve.Nthawi zambiri, mavavu a mpira okhala pawiri amakhala ndikuyenda kwapawiri.
12. Mukamasunga valavu, samalaninso vuto la madzi olowa mumutu wamagetsi ndi njira yake yotumizira.Makamaka mvula yomwe imalowa m'nyengo yamvula.Imodzi ndikuchita dzimbiri njira yopatsira kachilomboka kapena dzanja lopatsira, ndipo linalo ndikuundana m'nyengo yozizira.Vavu yamagetsi ikagwiritsidwa ntchito, torque ndi yayikulu kwambiri, ndipo kuwonongeka kwa magawo otumizira kumapangitsa kuti galimotoyo isadzalemedwe kapena ulendo wautali woteteza torque, ndipo ntchito yamagetsi siyingachitike.Zigawo zotumizira zimawonongeka, ndipo ntchito yamanja siyingachitike.Pambuyo pachitetezo chachikulu cha torque, kugwiritsa ntchito pamanja sikungathenso kusinthana, monga kukakamiza, kuwononga magawo a aloyi amkati.
Mwachidule, kukonza ma valve kumachitidwadi ndi malingaliro asayansi, kuti ntchito yokonza ma valve ikwaniritse zotsatira zake ndi cholinga chake.
