Chimodzi: Chifukwa chiyani ma dampers oyenda bwino amagwiritsidwa ntchito mumakina otsetsereka

Ma dampers a mzere amagwiritsidwa ntchito kwambiri mumakina otsetsereka pazifukwa zingapo zaukadaulo:

1. Kulinganiza kwa vekitala (kufananiza mayendedwe mwachindunji)

Kuyenda kotsetsereka kumakhala kolunjika. Pistoni ya damper yolunjika imayenda motsatira njira yomweyo yolunjika, kotero mphamvu yochepetsera imagwira ntchito molunjika motsatira njira yosunthika. Mphamvu imayamwa popanda kusintha kwa makina pakati. Kugwiritsa ntchito damper yozungulira potsetsereka nthawi zambiri kumafuna rack-and-pinion kapena njira yofanana yosinthira kuti isinthe kusuntha kwa mzere kukhala kuzungulira. Kusintha kumeneko kumabweretsa kutayika kwina, malo owonjezera owonongeka, komanso kubwereranso kumbuyo, kuchepetsa kugwira ntchito bwino komanso kudalirika.

2. Mphamvu vs. mphamvu: kukula ndi kugwiritsidwa ntchito

Machitidwe otsetsereka monga ma drawer olemera kapena zitseko zotsetsereka zamafakitale nthawi zambiri zimakhala ndi mphamvu zotsatizana komanso mphamvu zogundana. Choletsa chowongolera chowongolera chingapangidwe (posintha kukula kwa pistoni, mawonekedwe a orifice, ndi njira zoyendera mkati) kuti chipereke mphamvu zowongolera zochepetsera kuyambira ma newton angapo mpaka ma kilonewton angapo, zoyenera mphamvu zazikulu zowongolera.Zopopera zozunguliraamapanga mphamvu ndipo ndi oyenera kwambiri ku zivindikiro zopindika, zolumikizira, kapena zophimba zazing'ono zopanda mphamvu zambiri. Ngati yankho lozungulira likakamizika kulowa mu linear application yokhala ndi mphamvu zambiri, magiya oyendetsa kapena zinthu zotumizira zimatha kudzaza kwambiri ndikulephera.

3. Fomu ndi kuphatikiza

Ma damper ozungulira nthawi zambiri amakhala ma silinda aatali, opyapyala omwe amatha kubisika mkati mwa njira zotsetsereka kapena m'ming'alu yopapatiza, zomwe zimagwirizana ndi mapangidwe amakono okongola komanso osawoneka bwino. Ma damper ozungulira amafuna malo ozungulira ndipo, ngati agwiritsidwa ntchito ndi rack, amafunika malo oti azitha kuzungulira—nthawi zambiri sagwira ntchito kapena sagwira ntchito bwino mkati mwa ma slide otsekedwa.

4. Kuwongolera kosavuta kwa mphamvu yomwe mukufuna (kukana koyambirira kwa zero, kuchepetsa mphamvu kumapeto kwa sitiroko)

Zinthu zambiri zotsetsereka zimafuna kumveka kopepuka, kosavuta panthawi yonse yoyenda koma kupopera kwamphamvu pafupi ndi kumapeto kuti zisagwe. Ma linear dampers amatha kukwaniritsa khalidweli la "kuwala kenako mphamvu" mwa kusintha mawonekedwe a orifice, njira zambiri, kapena ma piston profiles, zomwe zimathandiza kuti pakhale kukana koyambirira kwa zero ndikuwonjezera kupopera pamene piston ikuyandikira kumapeto kwa sitiroko. Kukwaniritsa khalidwe lomwelo kudzera mu kusintha kwa rotary-to-linear n'kovuta kwambiri komanso kosalimba.

Kuti mudziwe zambiri za mfundo yogwirira ntchito, onani nkhani yathuKodi Damper Yoyambira Ndi Chiyani?.

二. Ma dampers a Linear a machitidwe otseka mofewa a drawer

Kutsegula/kutseka bwino makabati kumadalira zida zotsekera ndi chinyezi. Popanda chinyezi, kabati idzagundana ndi malo omalizira pansi pa inertia, zomwe zimayambitsa phokoso ndi kupsinjika kwa zigawo. Kuphatikiza choziziritsira cha mzere mu gulu la ma slide—kapena kugwiritsa ntchito ma slide opangidwa ngati ma slide ofewa otsekera kapena ma slide ofewa otsekera—kumayambitsa kuchepa kwa mphamvu pamene kabati ikuyandikira kutseka, zomwe zimapangitsa kuti kabati ikhale chete, yopanda kugwedezeka komanso yofewa. Izi zimateteza kabati ndikukweza khalidwe lomwe limawonedwa.

1. Zopopera zolumikizira zitseko zotsetsereka

Pa zitseko zolemera zotsetsereka zomwe zimagwiritsidwa ntchito popanga zomangamanga ndi mafakitale (monga magalasi kapena mapanelo amatabwa olimba), zotchingira zolumikizira zimathandizira:

● Chitetezo — kupewa kutseka mwachangu komwe kungayambitse kugwedezeka kapena kuvulala kwa zala.

● Chitetezo cha zida — kuchepetsa kuwonongeka kwa magalimoto kumapeto kwa ulendo ndikuwonjezera moyo wa ma roller, njanji, ndi mafelemu.

● Chitonthozo — kuonetsetsa kuti munthu akuyenda bwino komanso molamulirika popanda kuyima mwadzidzidzi kapena kubwerera m'mbuyo.

2. Ma Dampers a Linear aHbanjaAzida zogwirira ntchito

Mu zipangizo zambiri zapakhomo monga ma uvuni, firiji, makabati a vinyo ndi makina otsukira mbale, chitseko nthawi zambiri chimatseguka pansi molunjika molunjika pansi. Kuti zitsimikizire kuti zitseke bwino komanso moyenera, zipangizozi nthawi zambiri zimakhala ndi njira yayifupi yoyendetsera mkati mwa chitseko.

Kumapeto kwa njira yotsogolera iyi, nthawi zambiri pamakhala ma damper oyenda pang'onopang'ono. Pamene chitseko chikuyandikira malo otsekedwa bwino, makina otsetsereka amayatsa damper yoyenda pang'onopang'ono, zomwe zimapangitsa kuti pisitoni yamkati isunthe ndikupanga mphamvu yonyowa yomwe imachepetsa kuyenda kotseka.

Kuchepetsa mphamvu kwa chitseko kumeneku kumaletsa chitseko kutsekedwa mwamphamvu kapena kubwereranso kumapeto kwa ulendo. Zotsatira zake, zopopera zamagetsi zimathandiza kuchepetsa phokoso, kuteteza ma hinges ndi kutsogolera njanji kuti zisagwe kwambiri, komanso kukonza kulimba kwa chipangizocho.

Pachifukwa ichi, zoziziritsa mpweya zolunjika zakhala zofunikira kwambiri pakupanga zitseko za uvuni zamakono ndi zitseko zotsukira mbale, zomwe zimathandiza kuti zitsekozo zitseguke bwino, mopanda phokoso, komanso mowongoleredwa.

Kusankha chopondera cholondola cha mzere choyendetsera makina otsetsereka

Kusankha cholondolacholetsa cholumikizira mzerekumafuna kulinganiza magawo akuthupi motsutsana ndi ntchito:

1. Mphamvu yonyowetsa madzi — Mphamvu yonyowetsa madzi iyenera kufanana ndi kulemera kosuntha ndi liwiro lotseka lomwe mukufuna komanso momwe limamvekera. Kunyowetsa madzi kwambiri kumapangitsa kuti ntchito ikhale yolimba; kucheperako kumalola kukhudza.

2. Stroke — Sungani kutalika kokwanira kwa stroke kuti damper ichepetse mphamvu ya gawo loyenda bwino. Onetsetsani kuti stroke ya damper ikugwirizana ndi kuyenda komwe kulipo.

3. Chilengedwe ndi kulimba — Pa kutentha kwambiri, fumbi, chinyezi, kapena kugwiritsa ntchito pafupipafupi, sankhani zopopera zokhala ndi zisindikizo zoyenera, zipangizo, ndi nthawi yovomerezeka ya kuzungulira.

4. Kuyika ndi kuyika — Kuyika ndi kukanikiza, kuyika, ndi kugawa komwe kulipo kumakhudza momwe damper imagwirira ntchito; tsatirani malangizo a wopanga kuti mukwaniritse magwiridwe antchito abwino.
