Kuzindikira zolakwika ndi njira yodzitetezera ku ma valve amagetsi a flange globe
Kuzindikira zolakwika ndi njira yodzitetezera ku ma valve amagetsi a flange globe
Chidule: Monga gawo lofunikira la machitidwe owongolera madzimadzi, magwiridwe antchito otetezeka, odalirika, komanso okhazikika amagetsi amagetsi a flange amakhudza mwachindunji magwiridwe antchito a dongosolo lonse. Komabe, pakugwiritsa ntchito, ma valve amagetsi a flange globe amatha kukumana ndi zovuta zosiyanasiyana zomwe zimakhudza momwe amagwirira ntchito komanso moyo wawo wautumiki. Nkhaniyi ikuyang'ana njira zowunikira zolakwika ndi njira zodzitetezera ku mavavu amagetsi a flange globe, ndicholinga chopereka maupangiri othandiza kwa akatswiri aumisiri.
1,Mawu Oyamba
Ma valve amagetsi a flange globe amagwiritsidwa ntchito kwambiri m'mafakitale monga mafuta, mankhwala, zitsulo, ndi mphamvu, okhala ndi mawonekedwe osavuta, kusindikiza bwino, komanso kugwira ntchito bwino. Komabe, pakugwira ntchito kwanthawi yayitali, chifukwa cha zinthu zosiyanasiyana, mavavu amagetsi a flange padziko lapansi amatha kukhala ndi zolakwika monga kutayikira, kupanikizana, komanso kusasunthika, zomwe zimapangitsa kuti pakhale zovuta zazikulu monga kuzimitsa kwa zida ndi ngozi zopanga. Chifukwa chake, kudziwa zolakwa ndi njira zodzitetezera ku ma valve amagetsi a flange globe ndikofunikira kwambiri.
2,Mitundu ndi zomwe zimayambitsa zolakwika mu mavavu amagetsi a flange globe
1. Kutayikira
Kutayikira ndi chimodzi mwazolakwika zofala kwambiri za mavavu amagetsi a flange, ndipo zifukwa zazikulu ndi izi:
(1) Valani kapena kuwonongeka kwa malo osindikizira: Pakugwiritsa ntchito nthawi yayitali, malo osindikizira amatha kukokoloka kwapakatikati komanso kutha, zomwe zimapangitsa kuchepa kwa ntchito yosindikiza.
(2) Kukalamba kodzaza: Filler ndi gawo lofunikira kwambiri kuti mutsimikizire kusindikiza kwa ma valve amagetsi a flange padziko lonse lapansi. Pambuyo pogwiritsidwa ntchito kwa nthawi yayitali, amatha kukalamba, kutha, komanso kutulutsa.
(3) Kuwonongeka kwa chivundikiro cha valve kapena chivundikiro cha valve: Chifukwa cha zinthu zakunja monga kutentha ndi kupanikizika, thupi la valve kapena chivundikiro cha valve chikhoza kusokoneza, zomwe zimapangitsa kuwonjezeka kwa kusiyana pakati pa malo osindikizira ndikuyambitsa kutuluka.
2. Kukakamira
Chiwonetsero chachikulu cha kutsekeka kwa ma valve otsekera kwamagetsi ndikokuti valavu ilibe kapena siyingatsegulidwe ndikutsekedwa, ndipo zifukwa zake ndi izi:
(1) Kukangana pakati pa tsinde la valavu ndi kulongedza: Kukangana kwa nthawi yaitali pakati pa tsinde la valve ndi kulongedza kumapangitsa kuti pakhale kugwedezeka kwapakati, zomwe zimapangitsa kuti pakhale kukangana pakati pa tsinde la valve ndi kulongedza.
(2) Tinthu tapakati: Tinthu tapakati timakonda kukakamira pakati pa diski ya valve ndi mpando wa valavu, zomwe zimapangitsa kuti valavu ikhale kupanikizana.
(3) Kukula kwamkati kwa ma valve: Zowonongeka zomwe zili mkati mwa valavu, kupanga makulitsidwe, kuchepetsa njira zamkati za valve ndikupangitsa kuti valavu ikhale yodzaza.
3. Kusuntha kosasinthika
Kusasunthika kwa machitidwe a valavu yamagetsi yamagetsi yamagetsi amawonetsedwa makamaka ndi liwiro losintha pang'onopang'ono komanso torque yayikulu, ndipo zifukwa zake ndi izi:
(1) Kusokonekera kwa mota: Galimoto yomwe ili mu cholumikizira magetsi imawonongeka kapena magwiridwe ake amachepa, zomwe zimapangitsa kuti torque ikhale yosakwanira.
(2) Kulephera kwa njira yopatsirana: Njira yopatsirana ndiyowonongeka, yotayirira kapena yowonongeka, yomwe imakhudza kutsegula ndi kutseka liwiro ndi torque ya valve.
(3) Chizindikiro chowongolera: Njira yowongolera imasokonekera, zomwe zimayambitsa kusakhazikika kwazizindikiro ndi ma valve osasinthika.
3,Njira yodziwira zolakwika zamavavu amagetsi a flange globe
1. Njira yowonera
Poyang'ana momwe valavu ikugwirira ntchito, kutayikira, ndi kuchuluka kwa kulongedza kwa valve, onetsetsani ngati valve yasokonekera.
2. Njira yabwino yodziwira matenda
Pogwiritsa ntchito masensa amawu kuti asonkhanitse ma siginecha amawu pakugwira ntchito kwa ma valve, kusanthula mawonekedwe amawu kuti adziwe ngati valavuyo ndi yolakwika.
3. Njira yodziwira kutentha
Yang'anirani kusintha kwa kutentha pakugwira ntchito kwa ma valve kudzera mu masensa a kutentha, fufuzani madera a kutentha kwachilendo, ndi kuzindikira zomwe zimayambitsa zolakwika.
4. Njira yodziwira kugwedezeka
Pogwiritsa ntchito masensa ogwedezeka kuti atolere zizindikiro zogwedezeka pakugwira ntchito kwa valve, kusanthula mawonekedwe a vibration kuti adziwe ngati valavuyo ndi yolakwika.
5. Hydraulic diagnostic njira
Unikani machitidwe a dongosolo ndikuzindikira chomwe chimayambitsa zolakwika pozindikira magawo monga kukakamiza ndikuyenda mkati mwa valavu.
4,Njira yodzitetezera yokonzekera mavavu amagetsi a flange globe
1. Kuyendera nthawi zonse
Yang'anani nthawi zonse mawonekedwe a valavu yamagetsi yamagetsi, yang'anani kuwonongeka ndi kuwonongeka kwa malo osindikizira, kulongedza, tsinde la valve ndi zigawo zina, ndipo yesetsani mwamsanga mavuto aliwonse omwe apezeka.
2. Kupaka mafuta nthawi zonse
Nthawi zonse muzipaka zinthu monga ma actuators amagetsi ndi njira zotumizira kuti zitsimikizire kuti ma valve akuyenda bwino.
3. Kuyeretsa nthawi zonse
Tsukani zinyalala ndi zosafunika mkati ndi kunja kwa vavu kuti mupewe kupanikizana kwa mavavu, kutuluka, ndi zina.
4. Konzani magwiridwe antchito
Sinthani moyenerera kutsegula ndi kutseka kwa valve, torque ndi magawo ena kuti mupewe kukhudzidwa kwambiri ndi kuvala.
5. Njira zothana ndi dzimbiri
Sankhani zida zoyenera zotsutsana ndi dzimbiri potengera mawonekedwe apakati kuti muwonjezere kukana kwa valavu.
6. Maphunziro ndi kuunika
Limbikitsani maphunziro ndi kuwunika kwa ogwira ntchito, kupititsa patsogolo luso la magwiridwe antchito, ndikuchepetsa zolakwika za anthu.
5,Mapeto
Kuzindikira zolakwika ndi njira yodzitetezera ya ma valve amagetsi a flange padziko lonse lapansi ndizofunikira pakuwonetsetsa kuti machitidwe owongolera madzimadzi akuyenda bwino komanso okhazikika. Powunika mitundu ndi zomwe zimayambitsa zolakwika, kuphatikiza njira zowunikira zolakwika ndi njira zodzitetezera, ndizothandiza kukonza magwiridwe antchito ndi moyo wautumiki wa ma valve amagetsi a flange globe. Muzochita zogwiritsidwa ntchito, njira zosiyanasiyana ziyenera kugwiritsidwa ntchito mosinthasintha malinga ndi zochitika zenizeni kuti zitsimikizire kuti valve ikugwira ntchito bwino.
