Ijekhi iphakamisa kanjani isisindo?

UJack uwuhlobo lwempahla yokuphakamisa elula nencane esebenzisa izingxenye ze-steel jacking njengamadivayisi asebenzayo futhi iphakamise izinto ezisindayo kubakaki abangaphezulu noma uzipho olungezansi ngaphakathi kwe-stroke.Isetshenziswa kakhulu emafektri, ezimayini, ezokuthutha nakweminye iminyango njengokukhanda izimoto nokunye ukuphakamisa, ukwesekwa kanye neminye imisebenzi.Isakhiwo sayo silula futhi siqinile, siyavumelana nezimo futhi sithembekile, futhi umuntu oyedwa angakwazi ukusithwala futhi asisebenzise.

Amajack ahlukaniswe abe yizinhlobo zemishini kanye ne-hydraulic.Amajekhi asetshenziswa kakhulu ahlanganisa ojeke abasebenzisa amanzi, izikulufu namajeke kagesi.

Empeleni, isimiso esiyisisekelo sokudluliswa kwe-hydraulic umthetho kaPascal, okungukuthi, ukucindezela koketshezi yonke indawo kuyavumelana.Kuhlelo lwebhalansi, ingcindezi ekhishwa i-piston encane incane uma kuqhathaniswa, kuyilapho ingcindezi ekhishwa i-piston enkulu nayo inkulu ngokuqhathaniswa, engagcina uketshezi lumile.Ngakho-ke, ngokudluliselwa koketshezi, ukucindezela okuhlukene emikhawulweni ehlukene kungatholakala, futhi inhloso yokuguqulwa ingafinyelelwa.Ujeke we-hydraulic ovame ukusetshenziswa abantu usebenzisa lesi simiso ukuze kuzuzwe ukudluliswa kwamandla.

I-equation eyisisekelo yokucindezela okumile (p=p0+ ρ GH), lapho ingcindezi yangaphandle engu-P0 yoketshezi oluqukethwe esitsheni esivaliwe ishintsha, inqobo nje uma uketshezi luhlala lusesimweni salo sangempela, ingcindezi nganoma isiphi isikhathi oketshezini izoshintsha. ngenani elifanayo, okuyisimiso sokudlulisa ingcindezi emile noma isimiso sePascal.

Uma ingcindezi ethile isetshenziswa kuphiston elilodwa ohlelweni olusebenza ngamanzi, kuzokwenziwa umfutho ofanayo kwenye ipiston.Uma indawo yepiston yesibili iphindwe ka-10 kuneyepiston yokuqala, amandla asebenza ku-piston yesibili azokhuphuka aphindwe ka-10 kuneyephiston yokuqala, kuyilapho ukucindezela kwamaphiston amabili kusalingana.

I-screw jack idonsa isibambo emuva naphambili, ikhipha uzipho, okungukuthi, iphusha imvume ye-ratchet ukuze ijikeleze, futhi igiya le-bevel elincane lishayela igiya elikhulu le-bevel ukuze lizungezise isikulufu sokuphakamisa, ukuze umkhono ophakamisayo ukwazi ukuphakanyiswa. noma wehliswe ukuze kuzuzwe umsebenzi wokuphakamisa ukungezwani, kodwa akulula njengejekhi ye-hydraulic.
