Kumvetsetsa Ma Valves a Gulugufe Ogwira Ntchito Kwambiri
Ma valve a gulugufe ogwira ntchito bwino kwambiri amawonjezera ntchito yofunika kwambiri yomwe ma valve a gulugufe amagwira ntchito m'mafakitale. Ma valve amenewa amatha kuwongolera bwino kayendedwe ka madzi. Chifukwa ma valve a gulugufe ogwira ntchito bwino kwambiri amalimbana kwambiri ndi zinthu zoopsa. Kutentha kwambiri ndi kupanikizika kwambiri sizimakhudza magwiridwe antchito awo. Makampaniwa amadalira iwo kuti agwire ntchito modalirika komanso mokhazikika.
1. Kodi valavu ya gulugufe yogwira ntchito bwino kwambiri ndi chiyani?
Ngakhale kuti valavu ya gulugufe yogwira ntchito bwino imagwiritsa ntchito kapangidwe kake kapadera, kapangidwe kake ndi mfundo yogwirira ntchito ndizofanana ndi mavalavu wamba a gulugufe. Imakhala ndi thupi la valavu, diski ya valavu, shaft ndi mpando wa valavu. Disk ya valavu imazungulira shaft kuti ilamulire kuyenda kwa madzi. Mpando wa valavu umapereka chisindikizo kuti usatuluke.
Ma valve a gulugufe ogwira ntchito bwino amadalira ma valve a gulugufe okhala ndi mawonekedwe awiri, ndipo ntchito yake imadalira makina apamwamba. Disiki ya valavu yopangidwa ndi mawonekedwe awiri imachoka pa mpando wa valavu kumayambiriro kwa njira yotsegulira, motero imachepetsa kukangana ndi kuwonongeka kwa pamwamba pa chotsekacho.
Ma valve a gulugufe ogwira ntchito bwino kwambiri amagwira ntchito bwino m'malo omwe ali ndi mphamvu zambiri. Makampani monga mafuta ndi gasi amafuna mphamvu yodalirika ya ma valve. Ma valve amenewa amatha kupirira kupsinjika komwe kungawononge ma valve wamba. Mphamvu zabwino kwambiri zotsekera zimaletsa kutuluka kwa madzi pansi pa mphamvu zambiri.
Makampani ayenera kumvetsetsa kuti ma valve a gulugufe ogwira ntchito bwino ndi ati? Kodi ayenera kuwagwiritsa ntchito liti? Kusankha koyenera kumatsimikizira kuti ntchito ikuyenda bwino komanso kuti dongosolo likhale lokhazikika. Ma valve a gulugufe ogwira ntchito bwino amapereka kudalirika kofunikira pakugwiritsa ntchito molimbika.
2. Makhalidwe a mavavu a gulugufe ogwira ntchito kwambiri, kusiyana ndi mavavu wamba a gulugufe
2.1 Kusankha zinthu
Ma valve a gulugufe ogwira ntchito bwino amagwira ntchito bwino m'malo ovuta, osatinso m'malo wamba, omwe ndi ovuta kwambiri, kotero chitsulo chabwino chiyenera kugwiritsidwa ntchito pa tsamba. Zipangizo zolimba zimapangitsa kuti zikhale zolimba komanso zodalirika. Chitsulo chosapanga dzimbiri ndi WCB ndi zosankha zofala. Chitsulo chosapanga dzimbiri sichimalimbana ndi dzimbiri ndipo chimalimbana ndi kutentha kwambiri. Kutha kupirira nyengo zovuta kumapangitsa ma valve awa kukhala ofunikira kwambiri.
2.2 Ukadaulo wotseka
Ukadaulo wotseka umagwira ntchito yofunika kwambiri pakugwira bwino ntchito kwa ma valavu. Zisindikizo zapamwamba zimateteza kutuluka kwa madzi ndikusunga kulimba kwa kupanikizika. Mapangidwe awiri ozungulira amapereka mphamvu zabwino kwambiri zotsekera. Mapangidwe awa amachepetsa kukangana ndi kuwonongeka kwa malo otsekera. Zotsatira zake zimakhala nthawi yayitali yogwirira ntchito komanso kuchepetsa zosowa zosamalira.
2.3 Kuyesa kwa kupanikizika
Ma valve a gulugufe ogwira ntchito bwino amatha kuthana bwino ndi malo omwe ali ndi mphamvu zambiri. Nthawi zambiri mpaka Class 300 (PN40). Kutha kusunga umphumphu pansi pa mphamvu ndikofunikira kwambiri. Makampani monga mafuta ndi gasi amafunika kuyang'anira kupanikizika kodalirika.
2.4 Kukana kutentha
Kukana kutentha ndi chizindikiro chachikulu cha momwe ma valvu amagwirira ntchito. Ma HPBV amatha kugwira ntchito kutentha kwambiri, nthawi zambiri mpaka 500°F (260°C) kapena kupitirira apo. Kutha kugwira ntchito kutentha kwambiri kumawonjezera kusinthasintha kwawo. Luso limeneli limawapangitsa kukhala oyenera kugwiritsa ntchito makina a nthunzi, kupanga magetsi, komanso kukonza mankhwala.
3. Kusiyana ndi ma valve wamba a gulugufe
Kusiyana pakati pa mavavu a gulugufe ogwira ntchito bwino kwambiri ndi mavavu wamba a gulugufe.

Malo oyeretsera madzi amagwiritsa ntchito ma valve a gulugufe amphamvu kwambiri kuti azitha kuyendetsa bwino kayendedwe ka madzi ndi madzi otayira. Ma valve amenewa amatha kuthana bwino ndi kupsinjika ndi kutentha kosiyanasiyana. Kutha kugwira ntchito moyenera m'mikhalidwe yovuta kumatsimikizira kuti njira yoyeretsera madzi ndi yabwino.
5. Zoyenera Kuganizira Posankha
5.1 Zofunikira pa Kugwiritsa Ntchito
Ma valve a gulugufe ogwira ntchito bwino ayenera kukwaniritsa zosowa zinazake. Mtundu ndi makhalidwe a madzi ziyenera kuyesedwa musanagule. Kuyeza kwa kuthamanga ndi kutentha kuyenera kugwirizana ndi zofunikira pa ntchito. Kusankha valve yoyenera kumatsimikizira kuti ikugwira ntchito bwino komanso yotetezeka.
5.2 Mikhalidwe Yachilengedwe
Mkhalidwe wa chilengedwe umagwira ntchito yofunika kwambiri posankha ma valavu a gulugufe. Kutentha kwambiri ndi malo owononga amafunika zinthu zolimba. Chitsulo chosapanga dzimbiri kapena PTFE zimapereka kukana kwabwino kwa dzimbiri. Kusankha koyenera kumawonjezera nthawi yogwira ntchito komanso kudalirika.
Powombetsa mkota
Ma valve a gulugufe ogwira ntchito bwino amapereka ubwino waukulu pantchito zamafakitale. Mwa kugwiritsa ntchito ma valve awa m'makina awo, mafakitale amapindula ndi kugwira ntchito bwino komanso kudalirika. Kapangidwe kake kolimba kamatsimikizira kuti magwiridwe antchito abwino kwambiri m'mikhalidwe yovuta kwambiri, ndikuwonjezera chitetezo ndi phindu lazachuma.
Ubwino Waukulu:
• Kugwira ntchito bwino: Ma valve ogwira ntchito bwino amapereka kutsika kwa mphamvu kochepa komanso kuyika pang'ono.
• Kugwiritsa ntchito bwino ndalama: Kapangidwe kopepuka kamachepetsa ndalama zomwe zimagwiritsidwa ntchito popanga zinthu komanso zosowa zosamalira.
• Kusinthasintha: Koyenera kugwiritsidwa ntchito kutentha kwambiri komanso kwakukulu.
Makampani ayenera kusankha ma valve a gulugufe oyenera kuti agwire ntchito bwino komanso kuti azitha kugwira ntchito bwino kwa nthawi yayitali.
