Ndi chiyani chomwe chimakupangitsani kuti mugwiritse ntchito mphamvu zochepa kuti mukweze galimoto yanu?Inde, ndi jack yomwe imatha kunyamulidwa ndi galimoto kuti igwire ntchito zamakina.Komabe, kuwonjezera pa jack yonyamula iyi, pali ma jacks osiyanasiyana pamsika.Jacks amatha kugawidwa molingana ndi makina opangira mphamvu.Tili ndi ma jacks amakina, ma jacks amagetsi, ma jacks a hydraulic ndi ma jacks a pneumatic.Mitundu yonse ya ma jacks imatha kukweza zinthu zolemera, koma minda yawo yogwiritsira ntchito, kukweza mphamvu ndi mapangidwe ake adzakhala osiyana.

A jack hydraulicndi makina omwe amagwiritsa ntchito mphamvu yamadzimadzi kuti agwire ntchito.Mothandizidwa ndi ma hydraulic jacks, zinthu zolemera zimatha kukwezedwa mosavuta ndi mphamvu zochepa.Nthawi zambiri, chipangizo chonyamulira chimagwiritsa ntchito masilinda a hydraulic kugwiritsa ntchito mphamvu zoyambira.Ma hydraulic jacks ali ndi ntchito zambiri m'njanji, chitetezo, zomangamanga, ndege, zida zonyamulira katundu, mafakitale opangira magetsi amadzi, migodi ndi nsanja zokweza.Kuyenda kosalala komanso kosalala kwa jack speed jack pansi pa katundu wosiyanasiyana kapena wokulirapo kumapangitsa jack hydraulic kukhala yoyenera pazomwe zili pamwambapa.Momwemonso, kugwiritsa ntchito ma jacks a hydraulic kungapereke mphamvu yokweza kwambiri pamtunda wautali.

Tikayang'ana m'mbuyo pa mbiri yakale, chilolezo cha jack portable hydraulic jack chinaperekedwa kwa Richard Dudgeon mu 1851. Izi zisanachitike, William Joseph Curtis adapempha chilolezo cha Britain cha jacks hydraulic mu 1838.

Matanki osungira mafuta kapena matanki osungiramo mafuta, ma hydraulic cylinders, mapampu, ma valve owunika ndi ma valve otulutsa ndi zigawo zofunika kwambiri za jacks za hydraulic, zomwe zimathandiza kukweza zinthu zolemetsa.Monga ma hydraulic system iliyonse, tanki yosungiramo mafuta imasunga mafuta a hydraulic ndikupereka mafuta oponderezedwa a hydraulic ku silinda yolumikizidwa mothandizidwa ndi pampu ya hydraulic.Vavu yoyang'ana yomwe ili pakati pa silinda ndi pampu idzawongolera kuyenda.Madzimadzi akalowa mu silinda ya hydraulic, pisitoni imatambasula ndikukakamiza silinda yachiwiri ya hydraulic.Mukamaliza ntchitoyo, valavu yotulutsa imagwiritsidwa ntchito pochotsa pistoni ya hydraulic.Kuchuluka kwa tanki yosungiramo madzi kapena buffer kudzatengera kufunikira kwamafuta a hydraulic kuti silinda ikule ndikubwerera.Zambiri zokhudzana ndi ma hydraulic jacks zafotokozedwa pansipa.

Kodi jack hydraulic jack imagwira ntchito bwanji?Mfundo yogwiritsira ntchito jacks hydraulic imachokera pa mfundo ya Pascal pressure.Ndiko kuti, kupanikizika komwe kumagwiritsidwa ntchito pamadzi osungidwa mu chidebecho kudzagawidwa mofanana kumbali zonse.Zigawo zofunika za jack hydraulic jack ndi hydraulic cylinder, makina opopera ndi mafuta a hydraulic (nthawi zambiri mafuta).Sankhani madzi a hydraulic jack poganizira zamadzimadzi ena (monga kukhuthala, kukhazikika kwamafuta, kusefa, kukhazikika kwa hydrolytic, ndi zina).Ngati musankha mafuta ogwirizana ndi hydraulic, adzakupatsani ntchito yabwino, yodzipaka mafuta komanso yosalala.Mapangidwe a hydraulic jack adzakhala ndi masilindala awiri (imodzi yaying'ono ndi ina yayikulu) yolumikizidwa wina ndi mnzake ndi mapaipi.Ma hydraulic silinda onse amadzazidwa pang'ono ndi mafuta a hydraulic.Pamene kupanikizika kwazing'ono kumagwiritsidwa ntchito pa silinda yaying'ono, kupanikizikako kumasamutsidwa mofanana ku silinda yaikulu kupyolera mumadzimadzi osasunthika.Tsopano, silinda yokulirapo ipeza mphamvu yochulutsa mphamvu.Mphamvu yogwiritsidwa ntchito pazigawo zonse za ma silinda awiriwo idzakhala yofanana.Komabe, mphamvu yopangidwa ndi silinda yokulirapo idzakhala yapamwamba komanso yolingana ndi malo apansi.Kuphatikiza pa silinda, jack hydraulic jack idzaphatikizanso makina opopera kuti akankhire madzi mu silinda kudzera pa valve ya njira imodzi.Vavu iyi idzaletsa kubwerera kwa mafuta a hydraulic kuchokera ku silinda ya hydraulic.

Zovala za botolondi jacks mbale ndi mitundu iwiri ya jacks hayidiroliki.Padi yonyamula yomwe imathandizidwa ndi shaft yoyima ndiyomwe imayang'anira kulemera kwa chinthu chokwezedwa.Ma Jacks amagwiritsidwa ntchito kukonza maziko agalimoto ndi nyumba, komanso ma lifti amfupi oyima.Ma Jacks amatha kupereka mitundu yambiri yokweza yoyima.Chifukwa chake, ma jacks awa amagwiritsidwa ntchito kwambiri pantchito zamigodi.Mosiyana ndi chonyamulira botolo, shaft yopingasa imakankhira chikhocho kuti chilumikizane ndi chonyamulira, kenako ndikuchikweza molunjika.

Titha kuganiza mozama titakambirana njira zina zothetsera ma hydraulic jacks.Nditani ngati jack hydraulic jack sangathe kukweza zinthu?Kutsika kwamafuta kumatha kukhala chifukwa cha vuto ili.Choncho, choyamba, muyenera kufufuza mlingo wa mafuta.Ngati mukuwona kuti kuchuluka kwa mafuta m'dongosolo sikukwanira, chonde onjezerani mafuta.Kutayikira kapena kulephera kwa chisindikizo kungakhale chifukwa china cha izi.Ngati gasket yawonongeka, gasket pa compression silinda iyenera kusinthidwa.
