Kumvetsetsa Mavavu Agulugufe Ogwira Ntchito Kwambiri
Mavavu agulugufe ochita bwino kwambiri amawonjezera ntchito yofunikira yomwe ma valve agulugufe amagwira pamafakitale. Ma valve amenewa amatha kuyendetsa bwino madzi amadzimadzi. Chifukwa mavavu agulugufe ochita bwino kwambiri amalimbana kwambiri ndi mikhalidwe yovuta kwambiri. Kutentha kwakukulu ndi kupanikizika kwakukulu sikumakhudza ntchito yawo. Makampaniwa amadalira iwo kuti agwire ntchito yodalirika komanso kukhazikika.
1. Kodi vavu yagulugufe yochita bwino kwambiri ndi chiyani?
Ngakhale kuti valavu yagulugufe yogwira ntchito kwambiri imakhala ndi mapangidwe apadera, kapangidwe kake ndi mfundo zogwirira ntchito ndizofanana ndi mavavu agulugufe wamba. Zimaphatikizapo thupi la valve, disc valve, shaft ndi mpando wa valve. Disiki ya valve imazungulira kuzungulira tsinde kuti ilamulire kutuluka kwa madzi. Mpando wa valve umapereka chisindikizo kuti asatayike.
Mavavu agulugufe ochita bwino kwambiri amadalira mavavu agulugufe aŵiri-eccentric, ndipo ntchito yake imadalira njira zapamwamba. Dimba la valve yopangidwa ndi magawo awiri limachoka pampando wa valavu kumayambiriro kotsegulira, potero kuchepetsa kukangana ndi kuvala pamalo osindikizira.
Mavavu agulugufe ochita bwino kwambiri amapambana m'malo opanikizika kwambiri. Makampani monga mafuta ndi gasi amafuna magwiridwe antchito odalirika a valve. Mavavuwa amatha kupirira zovuta zomwe zingawononge ma valve okhazikika. Kukwanitsa kusindikiza kwapamwamba kumalepheretsa kutayikira pansi pa kupsinjika kwakukulu.
Makampani ayenera kumvetsetsa kuti mavavu agulugufe ochita bwino kwambiri ndi chiyani? Nthawi yoti muzigwiritsa ntchito? Kusankha koyenera kumatsimikizira kugwira ntchito moyenera komanso kukhazikika kwadongosolo. Mavavu agulugufe ochita bwino kwambiri amapereka kudalirika kofunikira pakugwiritsa ntchito movutikira.
2. Mawonekedwe a ma valve agulugufe apamwamba kwambiri, kusiyana ndi ma valve wamba agulugufe
2.1 Kusankha zinthu
Ma valve agulugufe apamwamba amagwira ntchito bwino m'malo ovuta, osasiya malo wamba, omwe amangowonjezereka, choncho zitsulo zabwino ziyenera kugwiritsidwa ntchito pa tsamba. Zida zamphamvu zimapangitsa kuti zikhale zolimba komanso zodalirika. Chitsulo chosapanga dzimbiri ndi WCB ndizosankha zofala. Chitsulo chosapanga dzimbiri sichichita dzimbiri komanso chimalimbana ndi kutentha kwambiri. Kutha kupirira zovuta kumapangitsa mavavuwa kukhala ofunikira.
2.2 Tekinoloje yosindikiza
Ukadaulo wosindikiza umagwira ntchito yofunika kwambiri pakuwongolera ma valve. Zisindikizo zapamwamba zimalepheretsa kutayikira ndikusunga umphumphu wokakamiza. Mapangidwe apawiri-eccentric amapereka luso losindikiza bwino kwambiri. Mapangidwe awa amachepetsa kukangana ndi kuvala pamalo osindikizira. Zotsatira zake ndi moyo wautali wautumiki ndikuchepetsa zofunikira zosamalira.
2.3 Mulingo wazovuta
Mavavu agulugufe ochita bwino kwambiri amatha kuthana bwino ndi malo okhala ndi kupanikizika kwambiri. Nthawi zambiri mpaka Class 300 (PN40). Kukhoza kusunga umphumphu pansi pa zovuta ndizofunikira kwambiri. Mafakitale monga mafuta ndi gasi amafuna kuwongolera kuthamanga kodalirika.
2.4 Kusagwirizana kwa kutentha
Kukana kutentha ndi chizindikiro chachikulu cha ntchito ya valve. Ma HPBV amatha kugwira ntchito pakatentha kwambiri, nthawi zambiri mpaka 500°F (260°C) kapena kupitirira apo. Kukhoza kugwira ntchito pa kutentha kwambiri kumawonjezera kusinthasintha kwawo. Kutha kumeneku kumawapangitsa kukhala oyenera pamayendedwe a nthunzi, kupanga magetsi, komanso kukonza mankhwala.
3. Kusiyana kwa mavavu agulugufe wamba
Kusiyana pakati pa mavavu agulugufe ochita bwino kwambiri ndi mavavu agulugufe wamba.
3.1. Kamangidwe kamangidwe
Ma valve agulugufe ochita bwino kwambiri: nthawi zambiri amakhala ndi mawonekedwe owoneka bwino, kulumikizana pakati pa mbale ya valve ndi malo osindikizira kumachepetsedwa. Choncho zinthu zosindikizira zimakhala ndi moyo wautali.
Ma valve agulugufe wamba: mawonekedwe okhazikika, mbale ya valve ndi malo osindikizira amalumikizana kwambiri akamatsegula ndi kutseka, ndipo malo osindikizira amavala mwachangu.

Ma valve agulugufe ochita bwino kwambiri: amatha kugwiritsidwa ntchito pakatentha kwambiri, ndipo amatha kupitiriza kusindikiza pa kutentha kwambiri.
Mavavu agulugufe wamba: nthawi zambiri ndi oyenera kutentha pang'ono kapena kutentha kwanthawi zonse, ndi kutentha kochepa.
3.4. Zochitika zantchito
Ma valve agulugufe apamwamba kwambiri: amagwiritsidwa ntchito kwambiri m'mafakitale monga petrochemicals, gasi, nthunzi, mankhwala a madzi, kutentha kwakukulu ndi kupanikizika kwakukulu, koyenera kulamulira madzimadzi pansi pa zovuta.
Mavavu agulugufe wamba: amagwiritsidwa ntchito makamaka m'malo ocheperako monga machitidwe otsika amadzimadzi, HVAC, ndi njira zamakampani wamba, komanso momwe amagwiritsidwira ntchito ndizosavuta.
3.5. Kusankha zinthu
Ma valve agulugufe ochita bwino kwambiri: Thupi la valve nthawi zambiri limapangidwa ndi zinthu zosagwirizana ndi dzimbiri komanso kutentha kwambiri monga chitsulo chosapanga dzimbiri, wcb, ndi chitsulo cha alloy, ndipo zidindo nthawi zambiri zimakhala zosindikizira zachitsulo kapena zosindikizira zofewa.
Mavavu agulugufe wamba: Zida za thupi la vavu nthawi zambiri zimakhala chitsulo choponyedwa kapena chitsulo cha ductile, ndipo zosindikizira nthawi zambiri zimakhala zofewa zosindikizira monga mphira ndi polytetrafluoroethylene.
3.6. Mtengo
Ma valve agulugufe apamwamba kwambiri: Chifukwa cha mapangidwe ovuta, zipangizo zamakono, ndi njira zopangira zabwino, mtengo wake ndi wokwera, choncho mtengo wake ndi wokwera mtengo.
Mavavu agulugufe wamba: mawonekedwe osavuta, otsika mtengo, komanso otsika mtengo.
4. Kugwiritsa ntchito ma valve agulugufe apamwamba kwambiri
4.1 Mafuta ndi gasi
Poyeretsa migodi kumtunda ndi kumunsi kwa mtsinje wamakampani amafuta ndi gasi, ma valve agulugufe ogwira ntchito kwambiri amagwira ntchito yofunika kwambiri. Chifukwa kuthamanga kwambiri komanso kutentha kwamadzimadzi kumafunika kuyang'aniridwa bwino kuti zitsimikizire chitetezo ndi magwiridwe antchito. Kutha kusindikiza kwabwino kwambiri kwa mavavu agulugufe ochita bwino kwambiri kumalepheretsa kutayikira ndikusunga kukhulupirika.
4.2 Chemical Processing
Mankhwala owononga ndi ofala m'mafakitale opangira mankhwala. Mavavu agulugufe ochita bwino kwambiri amakhala ndi zomangamanga zokhazikika komanso amatha kusindikiza bwino kwambiri kuti athe kuthana ndi zovuta zamtunduwu.
4.3 Kupanga Mphamvu
Malo opangira magetsi amapindula ndi ma valve agulugufe ogwira ntchito kwambiri, makamaka mu machitidwe a nthunzi ndi ntchito za turbine. Kuwongolera molondola kwa nthunzi yotentha kwambiri ndikofunikira kuti mukwaniritse bwino ntchito komanso mphamvu zamagetsi.
4.4 Chithandizo cha Madzi
Malo oyeretsera madzi amagwiritsa ntchito ma valve agulugufe apamwamba kwambiri kuti asamalire kutuluka kwa madzi ndi madzi oipa. Ma valve awa amatha kuthana ndi zovuta zosiyanasiyana komanso kutentha. Kutha kugwira ntchito modalirika pansi pazovuta kumatsimikizira njira yabwino yothandizira.
5. Zosankha Zosankha
5.1 Zofunikira pakufunsira
Mavavu agulugufe ochita bwino kwambiri ayenera kukwaniritsa zosowa zenizeni. Mtundu wamadzimadzi ndi mawonekedwe ake ayenera kuunika musanagule. Kupanikizika ndi kutentha kuyenera kufanana ndi zofunikira zogwirira ntchito. Kusankha valavu yoyenera kumatsimikizira ntchito yabwino komanso chitetezo.
5.2 Mikhalidwe Yachilengedwe
Mikhalidwe ya chilengedwe imathandiza kwambiri posankha ma valve a butterfly. Kutentha kwakukulu ndi malo owononga amafuna zipangizo zolimba. Chitsulo chosapanga dzimbiri kapena PTFE imapereka kukana kwa dzimbiri. Kusankha koyenera kumawonjezera moyo wautumiki ndi kudalirika.
Powombetsa mkota
Ma valve agulugufe ochita bwino kwambiri amapereka maubwino ambiri pantchito zamafakitale. Pogwiritsa ntchito ma valve awa m'machitidwe awo, mafakitale amapindula ndi kuwonjezeka kwachangu ndi kudalirika. Mapangidwe amphamvu amatsimikizira kugwira ntchito bwino pansi pazovuta kwambiri, kukonza chitetezo ndi phindu lachuma.
Ubwino waukulu:
• Kuchita bwino kwa ntchito: Ma valve ochita bwino kwambiri amapereka kutsika kwapansi kwambiri komanso kuyika kophatikizana.
• Kutsika mtengo: Kupanga kopepuka kumachepetsa mtengo wazinthu ndi zofunikira pakukonza.
• Zosiyanasiyana: Zoyenera kutentha kwambiri komanso ntchito zazikuluzikulu.
Mafakitale ayenera kuika patsogolo kusankha ma valve agulugufe oyenera kwambiri kuti atsimikizire kukhazikika kwa nthawi yayitali komanso kuchita bwino.
