Njira Yopangira Ma Valves A Industrial

Onani Chithunzi Chachikulu
Munayamba mwadzifunsapo kuti ma valve a mafakitale amapangidwa bwanji?Dongosolo la chitoliro silimatha popanda ma valve.Popeza chitetezo ndi moyo wautumiki ndizo zomwe zimadetsa nkhawa kwambiri pamapaipi, ndikofunikira kuti opanga ma valve apereke ma valve apamwamba kwambiri.

Kodi chinsinsi cha mavavu ogwira ntchito kwambiri ndi chiyani?Ndi chiyani chomwe chimawapangitsa kukhala abwino pakuchita bwino?Ndi zipangizo?Kodi makina owerengera ndi ofunikira kwambiri?Zoona zake n’zakuti, zonsezi.Musanamvetsetse mwatsatanetsatane za valve ya mafakitale, munthu ayenera kudziwa zambiri za momwe ma valve amapangidwira.

Nkhaniyi ifotokoza za kupanga ma valve a mafakitale kuyambira pachiyambi mpaka kumapeto.Izi zitha kupatsa owerenga chidziwitso chokhudza kupanga ndi kukonza ma valve.

1. Dongosolo ndi Mapangidwe

Choyamba, kasitomala ayenera kuyitanitsa, kaya ndi valavu yosinthidwa mwamakonda kapena china chake chomwe chili pamndandanda wamapangidwe omwe alipo kale.Pankhani yokhazikika, kampaniyo ikuwonetsa kapangidwe kake kwa kasitomala.Kamodzi kuvomerezedwa ndi womalizayo, woimira malonda amaika lamulo.Makasitomala amaperekanso ndalama zodziwikiratu kwa kampaniyo.

2. Kufufuza

Kuyika maoda ndi mapangidwe kukayamba, dipatimenti yopangira zinthu idzayang'ana zida za tsinde, spool, thupi, ndi bonati.Ngati palibe zipangizo zokwanira, dipatimenti yopanga zinthu izi idzagula zinthuzi kuchokera kwa ogulitsa.

3. Kumaliza Kuwunika

Zida zonse zikapezeka, gulu lopanga limayang'ananso mndandandawo kuti zitsimikizire kuti zonse zatha.Ndi panthawiyinso kuvomereza komaliza kwa mapangidwewo kumachitika.Kuphatikiza apo, gulu lotsimikizira zaubwino limayang'ana zida bwino.Izi ndi kuonetsetsa kuti zopangira ndi zabwino kwambiri.

4. Njira Yopangira

Izi zikuphatikiza ntchito zambiri zokhudzana ndi kupanga ma valve a mafakitale.Chigawo chilichonse chachikulu chimapangidwa pachokha.Nthawi zambiri, pamakhala mndandanda womwe umakhala ndi mayina onse a zida zotsalira ndi zida zomwe zingagwiritsidwe ntchito pa chilichonse.

Ndipamene mtsogoleri wa gulu amapereka nthawi yopangira zenizeni, kuyambira pachiyambi cha ntchitoyi mpaka tsiku lomaliza.Komanso, mtsogoleri nthawi zambiri amapanga ndondomeko yatsatanetsatane yogwirira ntchito.

Zomwe takambirana pansipa ndi njira ziwiri zodziwika bwino za momwe ma valve amapangidwira.

#1: Njira Yoponya

Njira yojambula ikhoza kufotokozedwa mwachidule poyang'ana chithunzi chomwe chili pansipa.Dziwani kuti iyi si njira yonse.

● Thupi
Chinthu choyambirira chopangidwa kale chotsukidwa.Njira yotembenuza imachitika pambuyo poyeretsa.Kutembenuza ndi njira yochotsera zinthu zochulukirapo podula pogwiritsa ntchito lathe kapena makina otembenuza.Zimaphatikizapo kumangirira thupi lopangidwa kale ndi phiri ndi makina otembenuza.Makinawa amayenda mothamanga kwambiri.Pamene imazungulira, wodula mfundo imodzi amadula thupi kuti likhale lofunika komanso lopangidwa mwapadera.Kupatula apo, kutembenuka kungathenso kupanga grooves, mabowo, pakati pa ena.

Chotsatira ndikuwonjezera zitsulo zopangira, kawirikawiri, mkuwa ku zigawo zosiyanasiyana za thupi.Kuyika kwa mkuwa kumatsimikizira kusindikizidwa kwathunthu ndi koyenera kwa thupi.

Gawo lotsatira ndikupukuta thupi.Kenaka, akatswiri amapanga ulusi womwe umalola kuti ziwalo zina za valve zigwirizane ndi zigawo zina kapena mapaipi.Mavavu amafunikira mabowo kuti kubowola kumachitika pambuyo pa izi.Dziwani kuti valavu iliyonse ili ndi makulidwe osiyanasiyana a dzenje, malingana ndi zofunikira.Apa ndipamene malamulo ndi mfundo zimagwira ntchito.

Akatswiri amapenta ma valve ndi Teflon kapena mitundu ina ya elastomer.Pambuyo pa kujambula, kuphika kumayamba.Teflon amalumikizana ndi thupi kudzera mu kuphika.

● Mpando
Mpandowo umayenda mofanana ndi thupi.Popeza mpando uli mkati mwa thupi komanso ngati gawo la ntchito yake ya valve- kuti usindikize bwino- umafunika kugwirizana bwino ndi zomwe zimamangiriridwa.Pomwe thupi limakhala ndi Teflon yokha, mpando ngati chowonjezera cha mphira kuti mutsimikizire kukhala olimba.

● Tsinde
Monga momwe zilili ndi tsinde, siziyenera kukhala ndi kupanga zambiri.M'malo mwake, kudula izi m'miyeso yoyenera ndikofunikira.

#2: Njira Yopangira

Njira yachinyengo ikhoza kufotokozedwa mwachidule mu ndondomekoyi pansipa.Mofananamo, ndondomeko ili m'munsiyi imangowonetsa kuti njira yopangidwira ndi yotani.

● Kudula ndi Kupanga
Pambuyo posankha zakuthupi, njira yotsatira ndiyo kudula iwo mu utali wofunikira ndi m'lifupi.Chotsatira ndikupangira gawo lililonse pozitenthetsa pang'ono mpaka pamlingo wina wake.

● Kucheka
Gawo lotsatira ndikudula.Apa ndi pamene zinthu zowonjezera kapena burr zimachotsedwa.Kenaka, thupilo limawalitsidwa kuti liwumbe mu mawonekedwe oyenerera a valve.

● Kuphulitsa mchenga
Kuwombera mchenga ndi sitepe yotsatira.Izi zimapangitsa valavu kukhala yosalala komanso yoyera.Kukula kwa mchenga wogwiritsidwa ntchito kumadalira zofuna za makasitomala kapena miyezo.Mavavu amakonzedwa poyamba kuti achotse zolakwikazo.

● Makina
Machining kumawonjezera kukula ndi mawonekedwe a ulusi, mabowo ndi zokonda, kachiwiri, kutengera kapangidwe ndi zofunikira za kasitomala.

● Chithandizo cha Pamwamba
Vavu imagwira ntchito pamtunda pogwiritsa ntchito ma acid ndi zina.

5. Msonkhano

Assembly ndi gawo lomwe akatswiri amalumikiza zigawo zonse za valve kwa wina ndi mzake.Nthawi zambiri, msonkhanowo umachitika ndi manja.Ndipamene akatswiri amapereka manambala opanga ma valves komanso mayina malinga ndi malamulo omwe amatsatira monga DIN kapena API ndi zokonda.

6. Mayeso a Pressure

Mu gawo loyesa kuthamanga, ma valve amayenera kuyesedwa kwenikweni kuti atsike.Nthawi zina, mpweya wokhala ndi 6-8 bar pressure umadzaza valavu yotsekedwa kwa maola angapo.Itha kukhala kuyambira maola 2 mpaka tsiku, kutengera kukula kwa valve.

Ngati pali kutayikira pakatha nthawi, kukonza ma valve kumachitika.Apo ayi, valavu idzapita ku gawo lotsatira.

Nthawi zina, kutayikira kumadziwika ndi kuthamanga kwa madzi.Ngati valavu sichikutha pamene kuchuluka kwa madzi kumawonjezeka, imadutsa mayeso.Izi zikutanthauza kuti valavu imatha kupirira kupanikizika kowonjezereka.Ngati pali kutayikira, valavu imabwerera ku nyumba yosungiramo katundu.Akatswiri amayang'ana ngati pali kutayikira asanayambe kuyesanso kukakamiza kwa mavavu awa.

7. Kuyang'anira ndi Kuwongolera Ubwino

Panthawiyi, ogwira ntchito ku QA amatha kuyang'anitsitsa ma valve kuti afufuze ndi zolakwika zina.

Yang'anani pavidiyoyi kuti muwone momwe valavu ya mpira imapangidwira.

Powombetsa mkota

Njira yopangira ma valve a mafakitale ndizovuta zovuta.Sikuti ndi chilengedwe chophweka cha valve.Zinthu zambiri zimathandizira kuti zitheke: kugula zinthu zopangira, kukonza makina, kutentha, kuwotcherera, kusonkhana.Ma valve ayenera kuyesedwa mwamphamvu kuti awonetsetse kuti akugwira ntchito moyenera opanga asanawapereke kwa makasitomala.

Wina angafunse, nchiyani chimapanga valavu yapamwamba kwambiri?Chimodzi mwazinthu zomwe zimatsimikizira kudziwa ma valve apamwamba kwambiri ndikuyesa nthawi.Ma valves aatali amatanthawuza kuti ndi abwino.

Kumbali ina, pamene valavu ikuwonetsa kutuluka kwamkati, mwayi ulipo, njira zopangira zomwe zimagwiritsidwa ntchito sizili mkati mwazofunikira.Nthawi zambiri, ma valve abwino amatha kukhala zaka 5 pomwe otsika amatha mpaka zaka 3.
