Musainzi mune misimboti yakawanda inoshanda kutsanangura mamwe maitiro muhupenyu hwezuva nezuva. Imwe yemitemo inonyanyozivikanwa iyi ndeye Nheyo yaPascal. Iwo mutemo wenyama unotsanangura kuti kudzvanywa kunoita sei mumvura. Izvo zvakakosha kuti tinzwisise kuti zvingani zvinhu zvinoshanda muhupenyu hwedu hwezuva nezuva, senge mabhureki emota kana iyo hydraulic system yecrane.
Muchinyorwa chino tichakuudza zvese zvaunoda kuti uzive nezve Pascal musimboti, kukosha kwayo uye kufambira mberi kwesainzi.
Nheyo yaPascal
Nheyo yaPascal inotiudza kuti kana tikashandisa dzvinyiriro pane imwe nzvimbo yemvura yakavharwa, kudzvinyirirwa ikoko kuchafambiswa zvakaenzana kumativi ose uye mumvura yose. Ndiko kuti, kana tikadzvanya mvura kune imwe mugumo wemudziyo wakavharwa, simba rimwechete richagoverwa zvakaenzana mumativi ose emvura uye pamadziro ose emudziyo.
Somuenzaniso, fungidzira une bharumu rakazara nemvura. Kana iwe ukaisvina kune imwe mugumo, kudzvanywa kunozofambiswa mumvura uye bharumu rinokanganisa kumativi ese. Kana iwe ukamanikidza zvakanyanya, iyo deformation ichave yakanyanya. Izvi zvinodaro nekuti mvura imvura uye inoteedzera musimboti waPascal.
Mutemo uyu wakakosha zvakare muinjiniya, kubvira inokutendera iwe kuti ugadzire ma hydraulic masisitimu anogona kuendesa huwandu hukuru hwesimba uye simba nekushomeka kushoma. Semuenzaniso, mune crane hydraulic system, mvura inoshandiswa kufambisa simba kubva pamota kuenda kuruoko rwecrane, ichibvumira zvinhu zvinorema kuti zvisimudzwe zviri nyore.
Kushanda
Pascal's musimboti unoshanda kune zvishandiso zvinoda kushandisa madiki kana akasununguka masimba kuti awane akasimba mhedzisiro. Semuenzaniso, muenzaniso wakajairika wemusimboti waPascal ndiyo musimboti we hydraulic pressure machine, asi isu tinogona zvakare kutaura nezve hydraulic brake yemota, chinosimudza mutoro, hydraulic jack, hydraulic steering yemotokari, uye kunyangwe pachigaro. yavanachiremba vemazino. Nheyo yaPascal yakakosha zvikuru mukudzidza kwehydrostatics.
Hydrostatics ibazi remvura mechanics, uye inodzidza zvinwiwa pakuzorora uye kumanikidza kunoitwa pavari. Hydrostatics yakakosha kuinjiniya uye inoshandiswa kuchengetedza, kutakura uye kushandiswa kwemvura.
Mienzaniso yePascal's Principle
Hydraulic muchina
Nheyo yaPascal Inoshandiswa zvakanyanya mu hydraulic press. A hydraulic press imuchina unoshandiswa kuisa simba guru pachinhu chakaita sepepa resimbi kana bhuroko rehuni. Izvi zvinoitwa kuburikidza nekushandiswa kwemvura inofambiswa kuburikidza nepiping system.
Iyo hydraulic press inoshanda nekuda kwePascal's musimboti, iyo inotaura kuti kudzvanywa kunofambiswa zvakafanana mumvura. Muchina wekudhinda une mapistoni maviri, imwe diki uye imwe hombe, yakabatanidzwa nechubhu yakazadzwa nemvura, semafuta kana mvura. Kana isu tikaisa simba papiston diki, kudzvanywa kunogadzirwa kunofambiswa mukati memvura yese uye kunosvika piston hombe.
Sezvo piston hombe iine nzvimbo yakakura kupfuura pisitoni diki, simba rinoshandiswa papiston diki rinowanzwa papiston huru. Semuenzaniso, kana piston hombe iine nzvimbo yepamusoro kakapetwa ka10 kupfuura piston diki, simba rinoiswa papiston diki richawedzerwa negumi papiston hombe. Izvi zvinoreva kuti tinogona kushandisa simba rakakura kwazvo pachinhu tichishandisa hydraulic press pane nesimba redu pachedu.
Hydraulic presses inoshandiswa mumashandisirwo akawanda akadai se kugadzirwa kwesimbi, kugadzirisa injini uye kudzvanywa kwezvinhu zvekuvaka. Mukuwedzera, dzinobatsira zvikuru mumamiriro ezvinhu apo simba guru rinodiwa kuti rishandiswe nemazvo, sezvo tichigona kudzora kuwanda kwesimba rinoshandiswa pachinhu chacho.
Hydraulic jack
Nheyo yaPascal inoshandawo kune hydraulic jacks, chishandiso chinobatsira zvikuru pakusimudza zvinhu zvinorema, semotokari. A hydraulic jack inoumbwa nemasilinda maviri akabatanidzwa nechubhu yakazadzwa nemvura. Rimwe remacylinders ihombe uye rakabatana nechikuva chakati sandara panogarira chinhu chinosimudzwa, rimwe racho idiki uye rakabatana necrank inoshandiswa kuisa simba.
Kana simba rikaiswa ku crank, kudzvanywa kunogadzirwa mumvura inofambiswa zvakaenzana kune yese hydraulic system, kusanganisira cylinder hombe inotsigira chinhu chinosimudzwa. Simba rinoshandiswa pahumburumbira diki rinowedzerwa pahumburumbira huru nekuda kwekusiyana kwehukuru pakati pemasirinda maviri, zvichiita kuti zvinhu zvinorema zvikuru zvisimudzwe zviri nyore.
Pascal's musimboti unoiswa mu hydraulic jack nenzira imwechete seyomu hydraulic press, kuve nechokwadi chekuti kudzvanywa kunofambiswa zvakaenzana kune yese hydraulic system uye kuti simba rinowedzerwa muhumburumbira huru kusimudza zvinhu zvinorema.
Hydraulic jacks inobatsira zvikuru muindasitiri yemotokari, sezvo ichibvumira mota kuti isimudzwe kuti igadziriswe uye kugadzirisa. Pamusoro pezvo, anobatsira zvikuru mune mamwe mabasa anoda kusimudza zvinorema, sekuvaka.
Nzira
Sezvinotarisirwa, muchinda wePascal anofanirwa kuverengerwa uchishandisa masvomhu mafomula. Kuverenga kudzvanywa mumvura iri kufambiswa ne hydraulic system, fomula P = F/A inoshandiswa, uko P iri kudzvanywa, F isimba rinoshandiswa, uye A inzvimbo yepasi pari kushandiswa simba.. Iyi fomula inotibvumira kuverenga kudzvanywa chero nguva mu hydraulic system.
Imwe fomula yakakosha ine chekuita nenheyo yaPascal mutemo wekuchengetedza simba. Mutemo uyu unosimbisa kuti simba rose muhurongwa hwakavharwa hunochengetedzwa, kureva kuti simba harigone kugadzirwa kana kuparadzwa, rinogona kushandurwa chete.
Mune hydraulic system, simba rinochengetedzwa sezvo simba rinoshandiswa pane imwe nguva richifambiswa nemumvura uye inoshandurwa kuita simba pane imwe nzvimbo muhurongwa. Izvi zvinoreva kuti simba rinoshandiswa pane imwe nguva mu hydraulic system yakaenzana nesimba rinowanikwa pane imwe nzvimbo.
Ndinovimba kuti neruzivo urwu unogona kuziva zvakawanda nezvePascal musimboti uye maitiro ayo.
