Kodi Valavu ya Mpira wa Pneumatic ndi chiyani?

Ma valve a mpira wa pneumaticMa valve a mpira oyendetsedwa ndi mpweya, ndi zinthu zofunika kwambiri m'mafakitale osiyanasiyana owongolera madzimadzi. Kapangidwe kawo kakang'ono, kugwira ntchito mwachangu, komanso kutseka kodalirika kumapangitsa kuti akhale abwino kwambiri pazinthu zosiyanasiyana. Nkhaniyi ikupereka chithunzithunzi chokwanira cha ma valve a mpira wa pneumatic, kuphatikizapo kapangidwe kawo, mfundo zogwirira ntchito, mitundu, ubwino, ntchito, kukhazikitsa, kukonza, ndi kuthetsa mavuto. Pomaliza, owerenga adzamvetsetsa bwino mtundu wa ma valve osinthasintha awa.

1. Chiyambi cha Ma Vavu a Mpira wa Pneumatic

Ma valve a mpira wa pneumatic ndi ma valve omwe amagwiritsa ntchito mpweya wopanikizika ngati gwero la mphamvu kuti azitha kutsegulira ndi kutseka valavu. Amapangidwa ndi thupi la valavu ya mpira, mpira (monga chinthu chotseka valavu), choyendetsa mpweya, ndi zowonjezera zina. Mpirawo uli ndi dzenje lozungulira kapena njira yodutsa mu mzere wake, ndipo pozungulira mpirawo madigiri 90, kuyenda kwake kumatha kutsegulidwa kwathunthu, kutsekedwa, kapena kukakamizidwa.

2. Kapangidwe ndi Mfundo Yogwirira Ntchito

Kapangidwe ka valavu ya mpira wa pneumatic kamachokera ku valavu yozungulira koma ndi kusintha kwakukulu. Zigawo zazikulu zikuphatikizapo:

Thupi la Vavu: Kawirikawiri amapangidwa ndi chitsulo chosungunuka, chitsulo chosapanga dzimbiri, kapena zipangizo zina zoyenera, thupi la valavu limasunga mpirawo ndipo limapereka njira yoyendera.

Mpira: Chibowo chopanda kanthu chokhala ndi dzenje lozungulira. Chikazunguliridwa madigiri 90, dzenjelo limagwirizana ndi malo olowera ndi otulutsira madzi kuti lilole kuyenda, kapena limasokonekera kuti lilepheretse kuyenda.

Choyambitsa Pneumatic: Chigawochi chimasintha mpweya wopanikizika kukhala kayendedwe ka makina kuti uzungulire mpirawo. Chimakhala ndi silinda, pisitoni, ndi ndodo yolumikizira.

Zisindikizo: Zisindikizo ndizofunikira kwambiri popewa kutuluka kwa madzi. Nthawi zambiri zimapangidwa ndi zinthu zopangidwa ndi elastomeric kapena zitsulo ndipo zimakhala pakati pa mpira ndi thupi la valavu.

Mfundo yogwirira ntchito ndi yosavuta: mpweya wopanikizika ukaperekedwa ku actuator, pisitoni imayenda, zomwe zimapangitsa kuti ndodo yolumikizira izungulire mpirawo. Kuzungulira kumeneku kumalumikiza kapena kusokoneza dzenje lolowera ndi madoko otulukira, motero kulamulira kuyenda kwa mpweya.

3. Mitundu ya Ma Vavu a Mpira wa Pneumatic

Ma valve a mpira wa pneumatic amatha kugawidwa m'magulu kutengera njira zosiyanasiyana:

Kapangidwe: Zitha kukhala mapangidwe a zidutswa ziwiri, zitatu, kapena chimodzi. Ma valve a zidutswa ziwiri ndi osavuta kusamalira, pomwe ma valve a chidutswa chimodzi amapereka magwiridwe antchito abwino otsekera.

Chisindikizo ChopangiraMa valve ofewa otsekedwa amagwiritsa ntchito zipangizo zopyapyala potseka, zoyenera kugwiritsidwa ntchito pa mphamvu yochepa komanso yosawononga. Ma valve otsekedwa mwamphamvu amagwiritsa ntchito kutseka kwachitsulo kuchokera kuchitsulo kupita kuchitsulo, koyenera kugwiritsidwa ntchito pa mphamvu yapamwamba komanso kutentha kwambiri.

Njira Yoyendera: Ma valve olunjika, a njira zitatu, ndi a ngodya alipo, kutengera zomwe njira yoyendera ikufunika.

Mtundu wa Actuator: Ma actuator ogwirira ntchito kawiri amagwiritsa ntchito mpweya wopanikizika kuti asunthe pisitoni mbali zonse ziwiri, pomwe ma actuator ogwirira ntchito imodzi amadalira kubwerera kwa masika mbali imodzi.

4. Ubwino wa Ma Vavu a Mpira wa Pneumatic

Ma valve a mpira wa pneumatic amapereka ubwino wambiri kuposa mitundu ina ya ma valve:

Kugwira Ntchito Mwachangu: Kuzungulira kwa madigiri 90 kuti mutsegule kapena kutseka kwathunthu kumapangitsa kuti ntchito igwire ntchito mwachangu.

Kapangidwe Kakang'ono: Kapangidwe kake kakang'ono kamalola kuyika kosavuta m'malo opapatiza.

Kukana Madzi Ochepa: Kapangidwe kake ka full-bore kamachepetsa kukana kwa madzi, kuchepetsa kutsika kwa kuthamanga kwa magazi ndi kugwiritsa ntchito mphamvu.

Kusindikiza Kodalirika: Zisindikizo zapamwamba kwambiri zimathandizira kuti madzi asatuluke kwambiri, ngakhale atakhala ndi mphamvu zambiri.

Kusinthasintha: Yoyenera mitundu yosiyanasiyana ya zinthu, kuphatikizapo madzi, mafuta, gasi, ndi mankhwala.

Kukonza Kosavuta: Mitundu yambiri imalola kuti zinthu zamkati zizitha kukonzedwa mosavuta.

5. Kugwiritsa Ntchito Ma Vavu a Mpira wa Pneumatic

Ma valve a mpira wa pneumatic amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kusinthasintha kwawo komanso kudalirika kwawo:

Makampani Opanga Mafuta: Amagwiritsidwa ntchito m'mapaipi kuti azitha kuyendetsa bwino mafuta, gasi, ndi mankhwala.

Kuchiza Madzi: Kuwongolera kayendedwe ka madzi ndi mankhwala oyeretsera m'malo oyeretsera madzi.

Chakudya ndi Chakumwa: Onetsetsani kuti muli aukhondo ndipo muziyang'anira kayendedwe ka zosakaniza ndi zinthu zokonzedwa.

Makampani Opanga Mankhwala: Amagwiritsidwa ntchito m'zipinda zoyera kuti azitha kuyendetsa bwino zinthu zomwe zikuyenda panthawi yopanga zinthu.

Zomera Zamagetsi: Kuwongolera kuyenda kwa nthunzi, madzi, ndi zinthu zina m'makina opangira magetsi.

Machitidwe Odzipangira Okha: Yophatikizidwa mu makina odziyimira pawokha kuti azitha kuyendetsa ndi kuyang'anira kutali.

6. Kukhazikitsa ndi Kukhazikitsa

Kukhazikitsa ndi kukhazikitsa bwino ndikofunikira kwambiri pakugwira ntchito kodalirika kwa ma valve a mpira wa pneumatic:

Kusankha Malo: Ikani valavu pamalo omwe amalola kuti igwire ntchito mosavuta. Onetsetsani kuti valavuyo yayikidwa mopingasa kapena pa ngodya yoyenera.

Kukonzekera kwa Paipi: Tsukani payipi musanayike kuti zinyalala zisawononge ma valve seal.

Kukhazikitsa Valavu: Tsatirani malangizo a wopanga poyika valavu, kuphatikizapo malangizo a mphamvu yomangira ndi kutseka.

Kulumikizana kwa ActuatorLumikizani choyatsira magetsi ku valavu ndi mpweya. Onetsetsani kuti maulumikizidwe onse ndi olimba komanso opanda madzi.

Kutumiza: Yesani valavu kuti igwire bwino ntchito musanayiyike pa ntchito. Yang'anani ngati pali kutuluka madzi ndipo onetsetsani kuti valavuyo ikutseguka ndi kutsekedwa bwino.

7. Kukonza ndi Kuthetsa Mavuto

Kukonza ndi kuthetsa mavuto nthawi zonse kumawonjezera moyo wa ma valve a mpira wa pneumatic ndikuwonetsetsa kuti amagwira ntchito modalirika:

Kuyendera: Yang'anani nthawi zonse valavu kuti muwone ngati pali zizindikiro zakutha, dzimbiri, kapena kuwonongeka. Yang'anani ngati pali kutuluka madzi mozungulira zomangira ndi choyeretsera.

Kupaka mafuta: Pakani mafuta pa ziwalo zoyenda monga momwe wopanga akulangizira kuti muchepetse kukangana ndi kuwonongeka.

Kuyeretsa: Tsukani valavu ndi choyeretsera nthawi zonse kuti muchotse dothi ndi zinyalala.

Kusintha Zisindikizo: Sinthani zomatira zosweka kapena zowonongeka mwachangu kuti zisatuluke madzi.

Kusaka zolakwikaNgati valavu yalephera kugwira ntchito bwino, yang'anani mpweya wotuluka, ntchito ya actuator, ndi mkati mwa valavu kuti muwone ngati pali zotchinga kapena kuwonongeka.

8. Zochitika ndi Zochitika Zamtsogolo

Makampani opanga ma valve a mpira wa pneumatic akusintha mosalekeza kuti akwaniritse zosowa za mafakitale. Zochitika zikuphatikizapo:

Zipangizo Zokonzedwanso: Kupanga zipangizo zatsopano zomangira ndi zomangira ma valve kumawonjezera kukana dzimbiri ndipo kumawonjezera nthawi ya moyo wa ma valve.

Ma Valves Anzeru: Kuphatikiza masensa ndi ukadaulo wolumikizirana kumathandiza kuyang'anira ndikuwongolera magwiridwe antchito a valavu patali.

Kugwiritsa Ntchito Mphamvu MoyeneraMapangidwe ake amakonzedwa bwino kuti achepetse kutsika kwa kuthamanga kwa magazi ndi kugwiritsa ntchito mphamvu, zomwe zimathandiza kuti zinthu ziyende bwino.

KusinthaOpanga amapereka njira zothetsera mavuto kuti akwaniritse zofunikira zinazake zogwiritsira ntchito, zomwe zimapangitsa kuti ma valavu azigwira bwino ntchito komanso kuti azidalirika.

Mapeto

Ma valve a mpira wa pneumatic ndiZigawo zodalirika komanso zosinthasintha m'makina owongolera madzi a mafakitale. Kapangidwe kawo kakang'ono, kugwiritsa ntchito mwachangu, komanso kutseka kodalirika kumapangitsa kuti zikhale zoyenera kugwiritsa ntchito mitundu yosiyanasiyana ya ntchito. Pomvetsetsa kapangidwe kawo, mfundo zogwirira ntchito, mitundu, ubwino, ntchito, kukhazikitsa, kukonza, ndi kuthetsa mavuto, ogwiritsa ntchito amatha kuwonetsetsa kuti ma valve awa akugwiritsidwa ntchito bwino komanso moyenera m'makina awo a mafakitale. Pamene ukadaulo ukupita patsogolo, ma valve a mpira wa pneumatic apitilizabe kusintha, kupereka magwiridwe antchito abwino, kugwiritsa ntchito mphamvu moyenera, komanso kusintha momwe zinthu zilili kuti zikwaniritse zosowa zosintha za ntchito zamafakitale.
