Maupangiri a Gawo ndi Magawo Posintha Chisindikizo cha Rubber wa Gulugufe

1. Mawu Oyamba

Kusintha zisindikizo za mphira pa ma valve a butterfly ndi njira yovuta yomwe imafuna chidziwitso chaumisiri, kulondola, ndi zida zoyenera kuti zitsimikizire kuti ntchito ya valve ndi kusindikiza kukhulupirika kumakhalabe. Buku lozama ili la akatswiri okonza ma valve ndi akatswiri amapereka malangizo atsatanetsatane, njira zabwino kwambiri, ndi njira zothetsera mavuto.

Kusunga mipando ya agulugufe ndikofunikira kuti zitsimikizire moyo wawo wautali komanso kuchita bwino. Komabe, m'kupita kwa nthawi, zosindikizira za rabara mu ma valve agulugufe zimatha kuwonongeka chifukwa cha zinthu monga kuthamanga, kutentha, ndi kukhudzana ndi mankhwala. Choncho, mipando ya valve imafuna kukonzanso nthawi zonse kuti zisawonongeke ndikuwonjezera moyo wa zigawo zofunikazi.
Kuphatikiza pa kudzoza mafuta, kuyang'anitsitsa, ndi kukonzanso panthawi yake kuti zisungidwe bwino, kusintha zisindikizo za rabara kuli ndi phindu lalikulu. Imawonjezera mphamvu ya valavu poletsa kutulutsa ndikuonetsetsa kuti chisindikizo cholimba, kuchepetsa nthawi yopuma ndikuwongolera kudalirika kwathunthu.
Bukhuli likukhudza ndondomeko yonse kuyambira pokonzekera kusintha mipando mpaka kuyezetsa komaliza, ndipo limapereka njira ndi njira zodzitetezera.

2. Kumvetsetsa mavavu agulugufe ndi zisindikizo za mphira

2.1. Kupanga ma valve a butterfly

Mavavu agulugufe amapangidwa ndi magawo asanu: valavu thupi,mbale ya valve, valavu ya valve,mpando wa valve, ndi actuator. Monga chinthu chosindikizira cha valavu ya butterfly, mpando wa valve nthawi zambiri umakhala pafupi ndi valavu ya valve kapena thupi la valve kuti zitsimikizire kuti madziwo sakutuluka pamene valavu yatsekedwa, motero amasunga chisindikizo cholimba, chopanda kutayikira.

2.2. Mitundu ya mipando ya butterfly valve

Mipando ya valavu ya butterfly imatha kugawidwa m'mitundu itatu.

2.2.1 Mpando wofewa wa valve, womwe ndi mpando wa valve wosinthika womwe watchulidwa m'nkhaniyi.

EPDM (ethylene propylene diene monomer rabara): kugonjetsedwa ndi madzi ndi mankhwala ambiri, abwino opangira madzi.

- NBR (rabara ya nitrile): yoyenera kugwiritsa ntchito mafuta ndi gasi chifukwa cha kukana kwake kwamafuta.

- Viton: Itha kugwiritsidwa ntchito pakutentha kwambiri chifukwa cha kukana kwake kutentha.

2.2.2 Hard backrest, mtundu uwu wa mpando wa valve ukhoza kusinthidwanso, koma ndizovuta kwambiri. Ndilembanso nkhani ina kuti ndifotokoze mwatsatanetsatane.

2.2.3 Mpando wa vavu wopindika, womwe ndi mpando wa valve wosasinthika.

2.3 Zizindikiro zosonyeza kuti chisindikizo cha rabala chiyenera kusinthidwa

- Zovala zowoneka kapena zowonongeka: Kuyang'ana thupi kumatha kuwulula ming'alu, misozi, kapena zopindika pachisindikizo.
- Kutayikira mozungulira valavu: Ngakhale pamalo otsekedwa, ngati madzi akutuluka, chisindikizocho chikhoza kuvala.
- Kuwonjezeka kwa torque yogwiritsira ntchito: Kuwonongeka kwa mpando wa valve kumapangitsa kuti valavu ya butterfly iwonongeke.

3. Kukonzekera

3.1 Zida ndi zida zofunika

Kuti musinthe bwino chisindikizo cha mphira pa valve ya butterfly, zida zapadera ndi zipangizo ndizofunikira. Kukhala ndi zida zoyenera kumapangitsa kuti pakhale njira yosinthira komanso yopambana.
- Wrenches, screwdrivers, or hexagon sockets: Zida izi zimamasula ndikumangitsa ma bolts panthawi yosinthira. . Onetsetsani kuti muli ndi ma wrenches osinthika, zotchingira ndi ma screwdriver a Phillips, ndi makulidwe osiyanasiyana a soketi za hexagon kuti mukhale ndi ma bolts osiyanasiyana.
- Mafuta: Mafuta, monga mafuta a silikoni, amagwira ntchito yofunikira pakusunga mbali zosuntha za valve. Kugwiritsa ntchito mafuta oyenera kumachepetsa kukangana komanso kumalepheretsa kuvala.
- Nyundo yamphira kapena nyundo yamatabwa: Imapangitsa mpando kukhala wolimba kwambiri motsutsana ndi thupi la valve.
- Mpando watsopano wa vavu: Chisindikizo chatsopano cha rabara ndi chofunikira pakusinthanso. Onetsetsani kuti chisindikizocho chikukwaniritsa zofunikira za valve ndi momwe zimagwirira ntchito. Kugwiritsa ntchito zisindikizo zogwirizana kumapangitsa kuti zikhale zolimba komanso zogwira ntchito bwino.
-Zinthu zoyeretsera: Tsukani malo osindikizira bwino kuti muchotse zinyalala kapena zotsalira. Sitepe iyi imatsimikizira kuti mpando watsopano waikidwa bwino ndipo umalepheretsa kutuluka pambuyo poika.
-Magolovesi oteteza ndi magalasi: Onetsetsani chitetezo cha ogwira ntchito.

3.2 Konzekerani kusintha

3.2.1 Zimitsani mapaipi

 

Musanayambe kusintha mpando wa rabara pa valavu ya butterfly, onetsetsani kuti makinawo atsekedwa, osachepera valavu yomwe ili pamwamba pa valavu ya butterfly yatsekedwa, kuti mutulutse kuthamanga ndikuonetsetsa kuti palibe kutuluka kwamadzimadzi. Tsimikizirani kuti gawo la mapaipi latsitsimutsidwa poyang'ana kuchuluka kwa kuthamanga.

3.2.2 Valani zida zodzitetezera

 

 

Chitetezo chiyenera kukhala chofunikira kwambiri nthawi zonse. Valani zida zodzitetezera zoyenera, kuphatikiza magolovesi ndi magalasi. Zinthu izi zimalepheretsa ngozi zomwe zingachitike monga kuphulika kwa mankhwala kapena m'mbali zakuthwa.

4. Bwezerani chisindikizo cha rabara pa valve ya butterfly

Kusintha mphira chisindikizo pa avalavu ya butterflyndi njira yosavuta koma yovuta yomwe imafuna chidwi chatsatanetsatane. Tsatirani njira zomwe zili pansipa kuti mutsimikizire kuti zasintha bwino.

4.1 Momwe mungatsegule valve ya butterfly?

4.1.1. Tsegulani Vavu ya Gulugufe

Kusiya diski ya valve pamalo otseguka kwathunthu kudzateteza zopinga panthawi ya disassembly.

4.1.2. Masulani zomangira

Gwiritsani ntchito wrench kumasula ma bolts kapena zomangira zomwe zimateteza ma valve. Chotsani zomangira izi mosamala kuti musawononge ma valve.

4.1.3. Chotsani Vavu ya Gulugufe

Mosamala kokani valavu mu chitoliro, kuthandizira kulemera kwake kuti muteteze kuwonongeka kwa thupi la valve kapena disc.

4.1.4 Lumikizani choyatsira

Ngati cholumikizira kapena chogwirira chilumikizidwa, chotsani kuti mulumikizane ndi ma valve.

4.2 Chotsani mpando wakale wa vavu

4.2.1. Chotsani chisindikizo:

Sungunulani gulu la valve ndikuchotsa mosamala chisindikizo chakale cha rabara.
