Ma valve omwe amafunsidwa pafupipafupi mafunso 9 mayankho 9
1. N'chifukwa chiyani valavu yokhala ndi mipando iwiri imakhala yosavuta kugwedezeka pamene ikugwira ntchito ndi kabowo kakang'ono?ndi
Kwa pachimake chimodzi, pamene sing'anga ndi mtundu wotseguka-otseguka, kukhazikika kwa valve ndikwabwino;pamene sing'anga ndi mtundu wothamanga-otseka, kukhazikika kwa valve kumakhala kovutirapo.Valve yokhala ndi mipando iwiri imakhala ndi ma spools awiri, spool yapansi imatsekedwa ndipo spool yapamwamba imatsegulidwa.Mwanjira iyi, pogwira ntchito potsegula pang'ono, spool yotsekedwa yothamanga idzapangitsa kuti valve igwedezeke mosavuta.Iyi ndiye valavu yokhala ndi mipando iwiri.Chifukwa chake sichingagwiritsidwe ntchito potsegulira zazing'ono.
2. Chifukwa chiyani valavu yosindikizira iwiri singagwiritsidwe ntchito ngati valavu yotseka?ndi
Ubwino wa valavu yokhala ndi mipando iwiri ndi mphamvu yoyendetsera mphamvu, yomwe imalola kusiyana kwakukulu, koma kuipa kwake kwakukulu ndikuti malo awiri osindikizira sangakhale ogwirizana nthawi imodzi, zomwe zimapangitsa kuti pakhale kutaya kwakukulu.Ngati amagwiritsidwa ntchito mongopeka komanso mokakamiza pazochitika zodula, zotsatira zake mwachiwonekere sizili zabwino, ngakhale zosintha zambiri (monga ma valve otsekedwa kawiri) zapangidwira, sizoyenera.
3. Ndi valavu iti yowongoka yowongoka yomwe ili ndi vuto loletsa kutsekereza, ndipo valavu ya quarter-stroke ili ndi ntchito yabwino yoletsa kutsekereza?ndi
Spool ya valve yowongoka imagwedezeka molunjika, pamene sing'anga imalowa ndi kutuluka mopingasa.Njira yodutsa muzitsulo za valve iyenera kutembenuka ndi kubwerera kumbuyo, zomwe zimapangitsa kuyenda kwa valve kukhala kovuta kwambiri (mawonekedwewo ali ngati mawonekedwe a "S" otembenuzidwa).Mwanjira iyi, pali madera ambiri akufa, omwe amapereka malo kwa mpweya wa sing'anga, ndipo ngati zinthu zikuyenda motere, zimayambitsa kutsekeka.Njira yokhotakhota ya quarter-turn valve ndiyo njira yopingasa.Sing'anga imayenda mopingasa ndipo imatuluka mopingasa.Ndikosavuta kuchotsa sing'anga yakuda.Panthawi imodzimodziyo, njira yothamanga ndi yophweka ndipo pali malo ochepa oti sing'angayo akhazikike, kotero kuti valve yozungulira kotala imakhala ndi ntchito yabwino yotsutsa-blocking.
4. Chifukwa chiyani tsinde la valve ya valve yowongoka yowongoka ndi yopyapyala?ndi
Zimakhudzanso mfundo yosavuta yamakina: kukangana kwakukulu kotsetsereka, kukangana kocheperako.Tsinde la valavu yowongoka imasunthira mmwamba ndi pansi.Ngati choyikacho chikanikizidwa pang'ono, chimakutira tsinde mwamphamvu, zomwe zimapangitsa kuti pakhale phokoso lalikulu.Kuti izi zitheke, tsinde la valavu lapangidwa kuti likhale lochepa komanso laling'ono ndipo kuyika zinthu kumagwiritsira ntchito PTFE yomwe ili ndi kagawo kakang'ono kameneka kameneka kuti tichepetse hysteresis.Koma vuto lomwe limachokera ku izi ndikuti tsinde la valve yopyapyala ndi yosavuta kupindika ndipo kuyikapo kumakhala ndi moyo waufupi wautumiki.Kuti athetse vutoli, njira yabwino ndiyo kugwiritsa ntchito tsinde la valavu yozungulira, valavu yoyang'anira yofanana ndi ya rotary stroke.Tsinde lake la valve ndi 2 mpaka 3 nthawi zambiri kuposa la valve yowongoka, ndipo graphite yonyamula ndi moyo wautali wautumiki imagwiritsidwa ntchito kupititsa patsogolo kuuma kwa tsinde la valve.Chabwino, kulongedzako kumakhala ndi moyo wautali wautumiki, koma makokedwe ake amakangana ndi ochepa ndipo hysteresis ndi yaying'ono.
5. Chifukwa chiyani kusiyana kwamphamvu kwa ma valve a kotala kutembenuka kuli kwakukulu?ndi
Ma valve a Quarter-turn ali ndi kusiyana kwakukulu kwa kuthamanga kwapakati chifukwa mphamvu yomwe imapangidwa ndi sing'anga pamtunda wa valve kapena mbale ya valve imapanga kamphindi kakang'ono kwambiri pamtunda wozungulira, kotero imatha kupirira kusiyana kwakukulu.
6. Kodi nchifukwa ninji mavavu agulugufe okhala ndi mizere ya raba ndi mavavu a diaphragm okhala ndi fluorine amakhala ndi moyo waufupi wautumiki wa madzi opanda mchere?ndi
Sing'anga yamadzi yopanda mchere imakhala ndi acid kapena alkali yochepa, yomwe imawononga kwambiri mphira.Kuwonongeka kwa mphira kumawonekera monga kukula, kukalamba, ndi mphamvu zochepa.Mavavu agulugufe ndi ma diaphragm okhala ndi mphira sagwiritsidwa ntchito bwino.Chofunikira ndichakuti mphirawo sulimbana ndi dzimbiri.Valavu yakumbuyo yokhala ndi mphira ya diaphragm idasinthidwa kukhala valavu ya diaphragm yokhala ndi fluorine yokhala ndi kukana kwa dzimbiri, koma diaphragm ya valavu ya diaphragm yokhala ndi fluorine sinathe kupirira kupindika mmwamba ndi pansi ndipo idasweka, kuwononga makina ndikufupikitsa moyo wa valavu.Njira yabwino kwambiri tsopano ndiyo kugwiritsa ntchito valavu yapadera ya mpira kuti iwononge madzi, yomwe ingagwiritsidwe ntchito kwa zaka 5-8.
7. Chifukwa chiyani valavu yodulidwa iyenera kutsekedwa mwamphamvu momwe zingathere?ndi
Valavu yodulidwa imafuna kutsika kwapang'onopang'ono, bwinoko.Kutuluka kwa valve yotsekedwa mofewa ndikotsika kwambiri.Zoonadi, zotsatira zodula ndi zabwino, koma sizimamva kuvala komanso zimakhala zodalirika.Tikayang'ana pa magawo awiri a kutayikira kwakung'ono ndi kusindikiza kodalirika, kudula chisindikizo chofewa sikwabwino ngati kudula chisindikizo cholimba.Mwachitsanzo, valavu yoyang'anira ultra-light yowonjezera yodzaza ndi yosindikizidwa ndi kutetezedwa ndi ma alloys osamva kuvala, ndi kudalirika kwakukulu ndi kutayikira kwa 10-7, komwe kumatha kukwaniritsa zofunikira za ma valve otseka.
8. N’chifukwa chiyani mavavu a m’manja analowa m’malo mwa mavavu okhala ndi mipando imodzi kapena iwiri?ndi
Mavavu a manja, omwe adatuluka m'ma 1960, adagwiritsidwa ntchito kwambiri kunyumba ndi kunja m'ma 1970.Mavavu am'manja adapanga gawo lalikulu lamafuta amafuta omwe adayambitsidwa mu 1980s.Pa nthawiyo, anthu ambiri ankakhulupirira kuti mavavu amatha kusintha mavavu amodzi kapena awiri.Vavu yapampando idakhala chinthu cham'badwo wachiwiri.Masiku ano, izi sizili choncho, ma valve okhala ndi mpando umodzi, ma valve okhala ndi mipando iwiri, ndi manja a manja onse amagwiritsidwa ntchito mofanana.Izi zili choncho chifukwa valavu ya manja imangowonjezera mawonekedwe ogwedeza, ndipo kukhazikika kwake ndi kukonza kwake kuli bwino kusiyana ndi valavu yokhala ndi mpando umodzi, koma kulemera kwake, zizindikiro zotsutsana ndi kutsekeka ndi zowonongeka zimagwirizana ndi ma valve okhala ndi mpando umodzi ndi awiri.Kodi angalowetse bwanji mavavu okhala ndi mipando imodzi kapena iwiri?Nsalu yaubweya?Choncho, angagwiritsidwe ntchito pamodzi.
9. N’chifukwa chiyani kusankha zitsanzo kuli kofunika kwambiri kuposa kuwerengera?ndi
Poyerekeza ndi kuwerengera ndi kusankha, kusankha ndikofunikira kwambiri komanso kovuta kwambiri.Chifukwa kuwerengera ndi njira yosavuta yowerengera, sikudalira kulondola kwa chilinganizocho, koma ngati magawo omwe apatsidwa ndi olondola.Kusankhidwa kwachitsanzo kumaphatikizapo zambiri, ndipo kusasamala pang'ono kudzatsogolera kusankhidwa kosayenera, zomwe sizidzangowononga anthu, chuma, ndi ndalama, komanso kumayambitsa zotsatira zosagwira ntchito, zomwe zidzabweretse mavuto ena ogwiritsidwa ntchito, monga monga kudalirika, moyo, ntchito khalidwe etc.
Chodzikanira: Nkhaniyi idapangidwanso kuchokera pa intaneti.Zomwe zili m'nkhaniyi ndi zophunzirira komanso kulumikizana kokha.Air Compressor Network salowerera ndale pamalingaliro omwe ali m'nkhaniyi.Ufulu wa nkhaniyo ndi wa wolemba woyambirira komanso nsanja.Ngati pali kuphwanya kulikonse, chonde lemberani kuti mufufute
