Chotenthetsera Madzi mu Makina Ochapira
Makina ochapira ndi chimodzi mwa zipangizo zapakhomo zomwe zimagwiritsidwa ntchito kwambiri. Ngakhale kuti ndi zosavuta, pali mavuto aukadaulo omwe ayenera kuthetsedwa kuti atsimikizire kuti ntchito yake ndi yokhazikika komanso chete komanso kupewa kuwonongeka msanga. Chinthu chimodzi chofunikira chomwe ogwiritsa ntchito nthawi zambiri amanyalanyaza ndi chida chodulira mafunde. Chinthuchi chimagwira ntchito yofunika kwambiri pakusunga bata panthawi yogwira ntchito komanso kuteteza kapangidwe ka makinawo ku kugwedezeka kwambiri. Nkhaniyi ikufotokoza za ntchito, mitundu, ntchito, zomwe zimayambitsa kuwonongeka, ndi malangizo osamalira ma damper odulira mafunde m'makina ochapira.
N’chifukwa Chiyani Makina Ochapira Amagwedezeka?
Kugwedezeka kwa makina ochapira kumachitika makamaka panthawi yozungulira/kuumitsa. Pa gawoli, ng'oma imazungulira mwachangu kwambiri kuti ichotse madzi m'zovala. Ngati katundu wa zovala sali bwino—mwachitsanzo, matawulo omangika mbali imodzi—pakati pa kulemera kwa ng'omayo pamasintha, zomwe zimapangitsa kuti mphamvu ya centrifugal isagwirizane. Izi zingayambitse makinawo kugwedezeka, kugwedezeka, kapena "kuyenda" pansi.
Kupatula kusalinganika kwa katundu, kugwedezeka kumakhudzidwanso ndi zinthu zina zingapo, monga:
1. Pansi pake pali pofanana kotero miyendo ya makina ndi yosakhazikika.
2. Kulemera kwambiri komwe kumawonjezera kukakamizidwa.
3. Kuwonongeka kwa zida zamakina pa chubu, bearing, kapena damper.
4. Liwiro lalikulu la injini zamakono ndi lolimba kwambiri kuposa mitundu yakale.
Popeza kugwedezeka ndi "kwachilengedwe" m'makina ozungulira mofulumira, cholinga cha kugwedezeka sikuchotsa kugwedezeka kwathunthu, koma kuwongolera kutalika ndikusintha mphamvu ya kugwedezeka kukhala mphamvu yotentha kuti isawononge.
Kodi Vibration Damper ndi chiyani?
Chotsukira madzi chogwedeza mu makina ochapira ndi chinthu chomwe chimathandiza kuchepetsa kugwedezeka kwa ng'oma ndi kugwedezeka pamene ikugwira ntchito, makamaka panthawi yozungulira. Mu mapangidwe ambiri a makina ochapira (makamaka omwe amanyamula katundu kutsogolo), ng'oma imayimitsidwa ndi makina osungunula okhala ndi ma springi ndi ma shock absorbers (ma dampers). Ma springi amathandizira katunduyo ndikulola ng'oma kuyenda, pomwe ma damper amalamulira kuyenda kuti apewe kugwedezeka kwambiri.
Mu makina ochapira ogwiritsidwa ntchito nthawi zambiri, kuvindikira kwa kugwedezeka nthawi zambiri kumaphatikizapo kuphatikiza ndodo zoyimitsidwa, ma bushings, ndi ma bearing zomwe zimapangitsa kuti ng'oma iyende bwino.
Ntchito Yaikulu ya Vibration Damper
Kawirikawiri, ma vibration dampers ali ndi ntchito zingapo zofunika:
1. Chepetsani phokoso ndi mantha
Makina ochapira okhazikika amakhala chete. "Magunda" amphamvu, kugwedezeka kapena kugwedezeka nthawi zambiri kumachepa pamene makina ochapira madzi akugwira ntchito bwino.
2. Kuteteza zigawo za injini
Kugwedezeka kwambiri kungachedwetse kuwonongeka kwa mabearing, shafts, malamba, ma motors, mafelemu, komanso ngakhale ma control board chifukwa zolumikizira ndi zingwe zimakumana ndi vuto la makina.
3. Wonjezerani chitonthozo ndi chitetezo
Makina oyenda kwambiri amakhala pachiwopsezo chogunda makoma, kuwononga pansi, kapena kuchititsa ogwiritsa ntchito kukhala ndi nkhawa akasiyidwa opanda woyang'anira.
4. Sungani zovala zabwino
Kugwedezeka kolamulidwa kumathandiza makina kusunga liwiro loyenera komanso kachitidwe kozungulira, zomwe zimapangitsa kuti njira yofinyira ikhale yogwira mtima kwambiri.
Mitundu ya Vibration Dampers mu Makina Ochapira
Wopanga aliyense angagwiritse ntchito kapangidwe kosiyana, koma kawirikawiri, zopopera zogwedeza pa makina ochapira ndi izi:
1. Chopopera Chotsitsa (Chopopera) Pakukweza Kutsogolo
Ichi ndi chinthu chofala kwambiri mu makina ochapira zovala kutsogolo. Chimafanana ndi choyatsira moto cha galimoto, koma chimagwira ntchito pogwiritsa ntchito makina okakamira kapena makina osavuta a hydraulic. Choyatsira moto chimalumikiza ng'oma ku chimango cha makinawo. Ng'oma ikasuntha, choyatsira moto chimaletsa kuyenda kuti chisagwedezeke.
2. Kasupe Woyimitsidwa
Spring imakhala pamwamba pa chubu, "kuiyika" kuti ikhale pakati pa injini. Spring siichepetsa mpweya ngati chopopera mpweya, koma m'malo mwake imathandizira katundu ndikusintha malo a chubu. Ngati spring ifooka kapena kumasuka, chubucho chimatha kuwerama, zomwe zimapangitsa kuti chigwedezeke kwambiri.
3. Ndodo Yoyimitsidwa Pamwamba Yokwezedwa
Magalimoto onyamula katundu pamwamba nthawi zambiri amagwiritsa ntchito ndodo zoyimitsira zinthu zokhala ndi masipuling ndi zibowo za rabara. Ndodo zimenezi zimasunga chubucho kukhala chokhazikika. Zibowo za rabara zimathandiza kuyamwa kugwedezeka ndikuchepetsa phokoso la kukangana.
4. Thandizo ndi Mapazi a Mphira Wotsutsana ndi Kugwedezeka
Kuwonjezera pa kutsukira mkati, makina ambiri ochapira ali ndi mapazi a rabara kapena mapadi oletsa kutsetsereka pansi. Izi zimaletsa makinawo kusuntha ndikuchepetsa kugwedezeka komwe kumapita pansi.
5. Kulemera kotsutsana
Mu makina olowetsa zinthu kutsogolo, opanga nthawi zambiri amaika zinthu zotsutsana ndi konkire kapena chitsulo kutsogolo kapena pamwamba pa silinda. Zinthu zotsutsana sizimaletsa mwachindunji, koma m'malo mwake zimawonjezera kulemera kuti makinawo akhale olimba komanso osagwedezeka kwambiri.
Momwe Vibration Dampers Imagwirira Ntchito Mwachidule
Tangoganizirani ng'oma ya makina ochapira ngati pendulum yopachikidwa. Ikazungulira mofulumira komanso mosakhazikika, pendulum imasuntha mbali ndi mbali. Ikanakhala kasupe chabe, ikanadumphadumpha nthawi zonse. Apa ndi pomwe damper imayambira: imapereka kukana kusuntha, zomwe zimathandiza kuti pendulum ibwerere pamalo ake okhazikika mwachangu.
Mwakuthupi, zopopera zimagwira ntchito pochotsa mphamvu ya kugwedezeka kudzera mu:
- kukangana (kuchepetsa kukangana), kapena
- kuyenda kwa madzi (hydraulic damping) m'mapangidwe ena.
Zotsatira zake, kayendedwe ka chubu kamakhala kolamulidwa bwino, osati kozungulira, ndipo makinawo "sadumpha".
Zizindikiro Zoti Choletsa Chanu Chakugwedezeka Chayamba Kulephera
Kuwonongeka kwa chotenthetsera madzi nthawi zambiri kumachitika chifukwa cha ukalamba, kugwiritsa ntchito mopitirira muyeso, kapena chizolowezi chosamba ndi zinthu zosakwanira. Zizindikiro zina zodziwika bwino ndi izi:
1. Makinawa amanjenjemera kwambiri akamazungulira ngakhale kuti katundu wake ndi wabwinobwino komanso wofanana.
2. Phokoso logunda ngati chubu chomwe chikugunda thupi la makina.
3. Makina amasintha malo ngakhale mapazi atasinthidwa.
4. Chubucho chimamveka chomasuka chikagwedezeka ndi dzanja (makina akazima).
5. Kutayikira kwa mafuta/zinyalala kumawonekera pa ma damper ena (kutengera kapangidwe kake).
6. Zovala zimakhalabe zonyowa kwambiri chifukwa kuzungulira kumasokonezeka chifukwa makina nthawi zambiri amachepetsa liwiro kuti apewe kugwedezeka.
Ngati zizindikirozi zachitika, ma damper ogwedera ayenera kuyang'aniridwa. Nthawi zina, vuto si ma damper okha, komanso ma suspension spring, miyendo ya injini, kapena ma tube bearing.
Zomwe Zimayambitsa Kuwonongeka kwa Damper
1. Kulemera kwambiri (katundu wapitirira mphamvu)
Kulemera kwambiri kumapangitsa kuti kuyimitsidwa kugwire ntchito mopitirira malire ake, zomwe zimapangitsa kuti dampers ndi bushings zisawonongeke mwachangu.
2. Kusalinganika kobwerezabwereza
Kutsuka zinthu zazikulu monga mabulangeti popanda malo oyenera kungayambitse kuti ng'oma igwedezeke nthawi zonse.
3. Pansi yosafanana
Ngati injini siikhazikika kuyambira pachiyambi, kugwedezeka pang'ono kudzakulitsidwa panthawi yozungulira.
4. Ubwino wa zigawo zimachepa chifukwa cha ukalamba
Rabala imakalamba, mafuta odzola amauma, ndipo makina okangana amasintha, zomwe zimafooketsa mphamvu yochepetsera kutentha.
Kukonza Kuti Zotenthetsera Zogwedeza Zikhale Zokhalitsa
Pali zizolowezi zosavuta zomwe zimathandiza kukulitsa moyo wa ma dampers anu:
1. Sinthani mapazi a makina mpaka atafika pamlingo woyenera.
Gwiritsani ntchito mlingo wa mzimu ngati ulipo, kapena onetsetsani kuti mapazi onse akugwirizana bwino ndi pansi.
2. Musapitirire mphamvu
Kuchuluka kwa makina nthawi zambiri kumawerengedwa pa zovala zouma. Musagwiritse ntchito zovala zolemera mopitirira muyeso, chifukwa zimayamwa madzi.
3. Gawani katundu bwino
Pakani zovala zamitundu yosiyanasiyana. Pewani kunyamula chinthu chimodzi chachikulu chomwe chingatseke mosavuta.
4. Gwiritsani ntchito pulogalamu yoyenera
