Kuyika valavu ya kusamvetsetsana kwa 10 sikunganyalanyazidwe kuyika ma valve otsegulira ndikugwiritsa ntchito zinthu zofunika kuziganizira.

Kuyika valavu ya kusamvetsetsana kwa 10 sikunganyalanyazidwe kuyika ma valve otsegulira ndikugwiritsa ntchito zinthu zofunika kuziganizira.

Ndi chitukuko chofulumira chaukadaulo komanso zatsopano, zidziwitso zamtengo wapatali zomwe ziyenera kuperekedwa kwa akatswiri amakampani nthawi zambiri zimabisika. Ngakhale njira zazifupi kapena njira zofulumira zitha kuwonetsa bajeti yanthawi yayitali, zikuwonetsa kusowa kwa chidziwitso komanso kumvetsetsa bwino zomwe zimapangitsa kuti dongosololi liziyenda bwino pakapita nthawi. Kutengera ndi zomwe zachitika, mndandanda wotsatirawu (wosafunikira kwenikweni) umatchula zolakwika 10 zodziwika bwino komanso zonyalanyazidwa mosavuta:
Ndi chitukuko chofulumira chaukadaulo komanso zatsopano, zidziwitso zamtengo wapatali zomwe ziyenera kuperekedwa kwa akatswiri amakampani nthawi zambiri zimabisika. Ngakhale njira zazifupi kapena njira zofulumira zitha kuwonetsa bajeti yanthawi yayitali, zikuwonetsa kusowa kwa chidziwitso komanso kumvetsetsa bwino zomwe zimapangitsa kuti dongosololi liziyenda bwino pakapita nthawi. Kutengera ndi zomwe zachitika, mndandanda wotsatirawu (wosafunikira kwenikweni) umatchula zolakwika 10 zodziwika bwino komanso zonyalanyazidwa mosavuta:
1. Maboti ndi aatali kwambiri
Kwa ma bolts pa valavu, ulusi umodzi kapena ziwiri zokha ziyenera kupitirira nati. Kuopsa kwa kuwonongeka kapena dzimbiri kungachepetse. Chifukwa chiyani mumagula bawuti yayitali kuposa momwe mukufunira? Nthawi zambiri, mabawuti amakhala aatali kwambiri chifukwa wina alibe nthawi yowerengera utali wolondola, kapena munthuyo samasamala momwe mapeto ake amawonekera. Uwu ndi uinjiniya waulesi.
2. Valve yowongolera siyipatula padera
Ngakhale kuti valavu yodzipatula imatenga malo ofunikira, ndikofunika kulola ogwira ntchito kuti agwire ntchito pa valve pamene kukonzanso kumafunika. Ngati danga lili lochepa, ngati valavu yachipata imaonedwa kuti ndiyotalika kwambiri, ikani valavu ya butterfly, yomwe imatenga pafupifupi danga. Nthawi zonse kumbukirani kuti ndizosavuta kuzigwiritsa ntchito komanso zogwira mtima kwambiri pakukonza mukayenera kuyimilira kuti muzikonza ndikugwira ntchito.
3. Palibe choyezera kuthamanga kapena chipangizo chomwe chimayikidwa
Zida zina zimakonda kulinganiza oyesa, ndipo malowa nthawi zambiri amagwira ntchito yabwino yopatsa ogwira nawo ntchito maulalo ku zida zoyesera, koma zida zina zimakhala ndi malo olumikizirana ndi zida zoyikira. Ngakhale kuti sizinatchulidwe, zimapangidwira kuti mphamvu yeniyeni ya valve iwonetsedwe. Ngakhale ndi kuyang'aniridwa ndi kuyang'anira deta (SCADA) ndi luso la telemetry, wina pamalo enaake adzayima pafupi ndi valve ndipo ayenera kuwona chomwe chikukakamiza, ndizosavuta.
4. Malo oyikapo ndi ochepa kwambiri
Ngati kuli kovuta kukhazikitsa siteshoni ya valve, yomwe ingaphatikizepo kukumba konkire, ndi zina zotero, musayese kupulumutsa ndalamazo pozipanga kukhala malo ochepa oyika momwe mungathere. Kukonzekera kofunikira pambuyo pake kungakhale kovuta kwambiri. Kumbukiraninso kuti zida zimatha kukhala zazitali kwambiri, choncho danga liyenera kukhazikitsidwa kuti malo azitha kumasula ma bolts. Mufunikanso malo, omwe amakulolani kuti muwonjezere zipangizo pambuyo pake.
5. Kuchotsa mochedwa sikuganiziridwa
Nthawi zambiri, okhazikitsa amamvetsetsa kuti simungathe kulumikiza zonse pamodzi mu chipinda cha konkire popanda kufunikira kugwirizana kwamtundu wina kuti muchotse mbali zina m'tsogolomu. Ngati mbali zonse zatsekedwa mwamphamvu ndipo palibe mipata, ndizosatheka kuwalekanitsa. Ma groove couplings, zolumikizira za flange ndi zolumikizira mapaipi ndizofunikira. M'tsogolomu, mbali zina zingafunike kuchotsedwa, ndipo ngakhale izi sizikhala zodetsa nkhawa kwa womangamanga, ziyenera kukhala zodetsa nkhawa kwa mwiniwake ndi injiniya.
6. Ikani chitoliro chochepetsera chopingasa mopingasa
Izi zitha kukhala nitpicking, koma ndiyenera kumvetsera. Eccentric reducer ikhoza kukhazikitsidwa mozungulira. Zochepetsera zapakati zimayikidwa mumizere yowongoka. M'mapulogalamu ena omwe amafunikira kuyika pamzere wopingasa, zochepetsera ma eccentric zimagwiritsidwa ntchito, koma vutoli nthawi zambiri limaphatikizapo mtengo: zochepetsera ma concentric ndizotsika mtengo.
7. Zitsime za Vavu zomwe sizimalola ngalande
Zipinda zonse zanyowa. Ngakhale pamene valve ikuyambitsa, madzi amagwera pansi nthawi ina pamene mpweya umatuluka kuchokera ku boneti. Aliyense m'makampani nthawi iliyonse adawona valavu yowonongeka, koma palibe chowiringula (pokhapokha, ndithudi, dera lonselo likusefukira, momwemo muli ndi vuto lalikulu). Ngati chitoliro chokhetsa sichingayikidwe, gwiritsani ntchito pompu yosavuta, potengera mphamvu yamagetsi. Valavu yoyandama yokhala ndi ejector imasunga bwino chipindacho ngati palibe mphamvu.
8. Osapatula mpweya
Kupanikizika kumatsika, mpweya umatuluka kuchokera kuyimitsidwa ndikulowetsedwa mu chitoliro, zomwe zingayambitse mavuto pansi pa valve. Valavu yosavuta yokhetsa magazi imachotsa mpweya uliwonse womwe ungakhalepo ndikuletsa mavuto akumunsi. Valavu yamagazi yomwe ili pamwamba pa valavu yolamulira imakhalanso yothandiza, chifukwa mpweya mu mzere wotsogolera ungayambitse kusakhazikika. Bwanji osachotsa mpweya usanafike pa valve?
9. Cholumikizira chosungira
Izi zikhoza kukhala vuto laling'ono, koma nthawi zonse zimakhala zothandiza kukhala ndi zogawanitsa zosungira m'zipinda zamtunda ndi pansi pa valve yolamulira. Kukonzekera uku kumathandizira kukonza kwamtsogolo, kaya ndikulumikiza ma hoses, kuwonjezera zomverera zakutali kuti ziwongolere mavavu kapena kuwonjezera zotumizira ku SCADA. Kwa mtengo wocheperako wowonjezera zowonjezera pazomwe zimapangidwira, zimawonjezera kwambiri kugwiritsa ntchito mtsogolo. Zimapangitsa kuti ntchito zokonza zikhale zovuta kwambiri chifukwa chilichonse chimakutidwa ndi utoto ndipo chifukwa chake ma nameplates sangathe kuwerengedwa kapena kusinthidwa.
10. Kumbukirani: Kuchita zinthu moyenera nthawi zonse kumakhala kopindulitsa, koma njira zachidule nthawi zambiri zimayambitsa mavuto. Ngakhale kuti mfundo 10 zimenezi zikhoza kuonedwa kuti n’zovuta kwambiri kwa ena, mphunzitsi wina wachikulire wanzeru nthawi ina anandiuza kuti, “Ukamatafuna nyama, ilavula fupalo.
Zolemba pa kukhazikitsa ndi kugwiritsa ntchito ma valve otsegulira Kuyika ndi kugwiritsa ntchito zofunikira zaukadaulo:
1, chipinda cha valve chiyenera kutsukidwa chisanakhazikitsidwe, ndi zolakwika zomwe zimachitika pamayendedwe;
2, mpweya valavu unsembe ayenera kusunga gulugufe valavu pagalimoto kutsinde ndi yopingasa, valavu pisitoni ofukula mmwamba malo;
3. Musanagwiritse ntchito valavu, chipangizo chotumizira chiyenera kusinthidwa kuti chisamalire ntchito za chipangizo chopatsirana, ndipo malire a sitiroko ndi chitetezo cha over-torque ndi odalirika;
4, ma valve kufala chipangizo kondomu mbali pamaso kutumidwa kuti mokwanira kuwonjezera mafuta mafuta;
5. Musanayambe chipangizo chamagetsi, werengani mosamala buku la chipangizo chamagetsi choperekedwa nacho.
Utumiki ndi kukonza
1. Yang'anani kutsegula ndi kutseka kwa valve nthawi zonse mukatha kugwiritsa ntchito, ndi kuthana ndi mavuto panthawi;
2. Dzazani mafuta opaka nthawi zonse kuti mukhalebe ndi mafuta abwino pazigawo zonse zosuntha;
3. Pambuyo pogwiritsira ntchito kwa nthawi, ngati apezeka kuti pisitoni sichikutsekedwa mwamphamvu, mphete ya pistoni iyenera kufufuzidwa ndikusinthidwa.
