Kufotokozera kwa Meta:Nyundo yamadzi imatha kuwononga mapaipi ndi ma valve m'makina osefera madzi olimba a mafakitale. Dziwani zomwe zimayambitsa nyundo yamadzi panthawi yotsuka m'mbuyo, momwe imakhudzira zida zosefera, komanso momwe VITHY Filtration'sFyuluta Yodziyeretsera ya VASndiVSRF Automatic Back-flushing Fyulutakuchepetsa chiopsezochi.
1. Kodi Madzi Hammer ndi Chiyani? Kodi Madzi Hammer amatanthauza chiyani mu kusefa madzi olimba m'mafakitale?
Nyundo yamadzi, yomwe imadziwikanso kuti hydraulic shock, ndi kukwera kwa kuthamanga kwa magazi komwe kumachitika pamene liwiro la madzi limasintha mwadzidzidzi [1]. Izi zitha kuchitika m'njira ziwiri wamba:
- Kuyimitsa kwadzidzidzi kwa madzi:Valavu ikatseka mwachangu, madzi oyenda amakakamizika kuyima, ndipo mphamvu yake ya kinetic imasanduka mafunde amphamvu omwe amabwerera kudzera mu chitoliro [2]. Iyi ndi njira yakale ya nyundo yamadzi.
- Kuthamanga kwa madzi mwadzidzidzi:Valvu ikatsegulidwa mwachangu, madzi osasuntha kapena oyenda pang'onopang'ono amafulumizitsidwa mwadzidzidzi. Chifukwa cha madzi omwe ali ndi vuto la kulephera kugwira ntchito ndipo kuthamanga kwa madzi m'mwamba kumakhala kokwera kale, kuthamanga kwa madzi kumeneku kungapangitsenso kuthamanga kwamphamvu kwa madzi, makamaka m'mizere yotulutsira madzi kapena yotulutsira madzi [4].
Mu kusefa madzi olimba m'mafakitale, nyundo yamadzi imachitika nthawi zambirigawo lotulutsa madzi kapena kutsuka msana. Pamene valavu yotulutsira madzi kapena valavu yotulutsira madzi ikutseguka mwadzidzidzi, madzi opanikizika amathamangira mumzere wotulutsira madzi nthawi yomweyo. Vavu ikatsegulidwa mwachangu, madzi oyambira amayamba kukwera kwambiri komanso kuthamanga kwa madzi kumachepa. Mu zosefera za zinthu zambiri, izi zimakhala zoopsa kwambiri chifukwa madziwo amatha kukhazikika mu nthambi imodzi kapena zingapo zokha.
Chifukwa chake, mu zosefera zodzitsukira zokha, nyundo yamadzi nthawi zambiri imachitika osati chifukwa chotseka valavu, koma chifukwa chakutsegula mwachangu valavu yotulutsira madzikutulutsa madzi ambiri opanikizika. Malinga ndi Hydraulic Institute [1], Engineering ToolBox [2], ndi Crane Technical Paper No. 410 [4], kuyimitsa kwadzidzidzi kwa madzi komanso kuthamangitsa kwadzidzidzi kwa madzi kumatha kubweretsa kukwera kwamphamvu kwa madzi m'mapaipi amafakitale.
2. Kodi Kuopsa kwa Madzi a Hammer Ndi Chiyani? Kodi Kuopsa kwa Mafakitale Osefera Madzi Ndi Chiyani?
Nyundo yamadzi si vuto la phokoso lokha. Ikhoza kuwononga kwambiri makina osefera mafakitale ndi zida zozungulira [3].
Zoopsa zofala zimaphatikizapo:
- Kuwonongeka kwa chitoliro ndi cholumikizira
Kukwera kwadzidzidzi kwa mphamvu kumatha kuswa mapaipi, kuswa ma flange, kapena kumasula malo olumikizirana. Mu makina osefera, mapaipi otulutsira madzi m'madzi amakhala osatetezeka kwambiri chifukwa nthawi zambiri amagwira ntchito yothira madzi kapena madzi onyansa [4].
- Kulephera kwa valavu
Ma valve otsegula kapena otseka mwachangu, monga ma valve a mpira wopopera mpweya kapena ma valve a solenoid, amatha kuwonongeka ndi nyundo yobwerezabwereza yamadzi. Mipando, zomatira, ndi ma actuator zimatha kutha msanga [2].
- Kugwedezeka ndi kupsinjika kwa makina
Kugwedezeka kwamphamvu kumatha kumasula mabawuti, kuwononga kulumikizana kwa zida, komanso kupangitsa kutopa kwa kapangidwe kake pakapita nthawi [4].
- Kuwonongeka kwa pampu ndi fyuluta
Kukwera kwa mphamvu kumatha kubwereranso m'mbuyo ndikukhudza nyumba ya fyuluta, zinthu zosefera, ndi mapampu akumtunda. Izi zimakhala zoopsa makamaka mu zosefera za cartridge yambiri kapena zamachubu ambiri komwe kuyenda kumakhala kokulirapo [1].
Mu kusefa madzi olimba m'mafakitale, vuto lofala kwambiri la nyundo yamadzi limachitika nthawi zambirikutsuka msana kokha. Pamene chinthu chimodzi kapena zingapo zokha zosefera zimatsukidwa kumbuyo nthawi imodzi, madzi otuluka amakhala ochuluka. Ngati valavu yotulutsira madzi imatsegulidwa mwachangu, kuthamanga kwa madzi mwadzidzidzi kumapanga mafunde amphamvu a kuthamanga. Mainjiniya a VITHY Filtration awona izi mu zosefera zina zotulutsira madzi otuluka kumbuyo: valavu yotulutsira madzi ikatsegulidwa, madziwo amakhala ambiri, kuthamanga kumakhala kwakukulu, ndipo kugwedezeka kumakhala kolimba mokwanira kuwononga chitoliro cha madzi otuluka pakapita nthawi.
Mosiyana ndi zimenezi, fyuluta yodziyeretsera yokha yokonzedwa bwino siingayambitse nyundo yamadzi. Mu fyuluta yokhetsera, njira yotulutsira madzi imakhala ndi mphamvu yochepa, ndipo madzi otuluka m'madzi amakhala ochepa. Chifukwa chake, kusintha kwa kuthamanga kumakhala pang'onopang'ono, ndipo kuchuluka kwa kugwedezeka kumakhala kochepa kwambiri. Izi zatsimikiziridwa ndi zomwe zachitika m'munda: makasitomala omwe amagwiritsa ntchito VITHY Filtration'sFyuluta Yodziyeretsera ya VASsindinanenepo za mavuto a nyundo ya madzi.
3. Kodi Mungapewe Bwanji Madzi Osalowa M'madzi Pantchito Zosefera Za Mafakitale Zatsiku ndi Tsiku?
Pali njira zingapo zothandiza zochepetsera kapena kupewa kugwiritsa ntchito nyundo yamadzi m'makina osefera. Zambiri mwa izi ndi zotsika mtengo ndipo zitha kugwiritsidwa ntchito m'malo omwe alipo kale [4].
(1) Chepetsani ntchito ya valavu
Gwiritsani ntchito ma actuator othamanga ndi mpweya kapena amagetsi okhala ndi mphamvu yowongolera liwiro. Kuwonjezera valavu yowongolera mpweya ku valavu ya solenoid kungapangitse valavu kutseguka ndi kutsekedwa pang'onopang'ono, kuchepetsa kuthamanga kwa mpweya. Komabe, njira iyi ingawonjezere kugwiritsa ntchito madzi panthawi yopuma chifukwa valavu imakhala yotseguka kwa nthawi yayitali [5].
(2) Mangani mapaipi otulutsira madzi
Mapaipi otulutsira madzi ayenera kuthandizidwa mwamphamvu ndikukhazikika kuti azitha kuyamwa kugwedezeka. Mapaipi osatetezedwa amatha kugwedezeka kwambiri pakasintha mwadzidzidzi mphamvu [4].
(3) Ikani valavu yolumikizira ndi manja
Valavu yosavuta yoyikidwa pa chingwe chotulutsira madzi imatha kutsekedwa pang'ono (monga, kutseguka kwa 50%) kuti ichepetse kutuluka kwa madzi ndikuchepetsa kukwera kwa kuthamanga. Mwa kuchepetsa kuthamanga kwa madzi, valavu yothira madzi imaletsa madziwo kuti asapitirire mofulumira kwambiri, ngakhale valavu yotulutsira madzi itatsegulidwa mwachangu. Iyi ndi njira yothandiza pa zosefera zomwe zilipo, koma iyenera kuyang'aniridwa nthawi zonse kuti zitsimikizire kuti malo a valavu sanasinthe [5].
(4) Gwiritsani ntchito kusankha bwino ma valavu
Sankhani ma valve okhala ndi nthawi yoyenera yotsekera makina. Pewani ma valve akuluakulu omwe amatseguka kapena kutseka mwachangu kuposa momwe mukufunira. Mu makina odziyimira pawokha, sankhani ma actuator okhala ndi liwiro losinthika [1].
(5) Ganizirani kapangidwe ka fyuluta
Njira yabwino kwambiri yothetsera vutoli kwa nthawi yayitali ndi kusankha fyuluta yomwe njira yake yotulutsira madzi ndi kapangidwe kake ka ngalande sizimawononga nyundo yamadzi. Izi ndizofunikira kwambiri pamapulojekiti atsopano kapena posintha zida zakale [3].

VSRF Automatic Back-flushing Fyuluta
Mndandanda wa VSRF wapangidwira ntchito zomwe zimafuna kutsukidwa kwa zinthu zosefera zokha. Mu fyuluta yotsukidwa yachizolowezi, pamene chinthu chimodzi kapena zingapo zokha zimatsukidwa nthawi imodzi, madzi amalowa ndipo kutsegula kwa valavu yotulutsira madzi kungayambitse kukwera kwamphamvu kwa mphamvu. VITHY Filtration yathetsa vutoli m'njira ziwiri:
(1) Kuwongolera liwiro la pneumatic pa ma drain valves
Valavu yowongolera mpweya imayikidwa pa valavu ya solenoid. Valavuyo imatha kuchepetsa kutseguka ndi kutseka kwa valavu. Izi zimachepetsa kwambiri kukwera kwa kuthamanga ndi kugwedezeka panthawi yopukutira kumbuyo. Tikukulimbikitsani kuti muyang'ane nthawi ndi nthawi nati yowongolera ya valavuyo kuti muwonetsetse kuti ikukhalabe yolimba bwino. Pakapita nthawi, kugwedezeka kungayambitse natiyo kumasuka, zomwe zingachepetse mphamvu ya kunyowa ndikulola nyundo yamadzi kubwerera.
(2) Malangizo a njira zochotsera madzi otayira madzi m'mitsinje
Ngati kuchepetsa valavu sikukukondedwa chifukwa kumawonjezera kugwiritsa ntchito madzi osambira m'mbuyo, tikupangira njira zina ziwiri:
- Konzani ndikuthandizira mapaipi otulutsira madzi kuti muchepetse kugwedezeka.
- Ikani valavu yogwiritsira ntchito pamanja pansi pa mtsinje ndipo isungeni pakati pokhapokha mukayitsuka kumbuyo. Izi zimachepetsa kuchuluka kwa madzi omwe amatuluka ndipo zimalepheretsa madziwo kuthamanga mofulumira kwambiri, popanda kuwonjezera kuchuluka kwa madzi omwe amagwiritsidwa ntchito.
Mwa kuphatikiza kapangidwe kabwino ka njira yoyendera madzi, kuyendetsa bwino ma valve, ndi upangiri wothandiza wokhazikitsa, VITHY Filtration imathandiza makasitomala kupewa zotsatira zokwera mtengo za nyundo yamadzi pomwe ikusunga kulekanitsa kodalirika kwa madzi olimba.
