I-pneumatic lifting jack: isixhobo kunye neenzuzo

I-jack ye-pneumatic yinkqubo yobugcisa obuyinkimbinkimbi eyenzelwe ukuphakanyiswa ngokukhawuleza kwanoma yimuphi umthwalo onzima. Isetyenziswe ikakhulu kwizikhululo zesevisi kunye neevenkile zokulungisa imoto, kodwa ngamanye amaxesha kunokubonakala kwiziko lokwakha. Nangona kunjalo, akumangalisi, kuba kuzo zombini iimeko kukho imfuneko yokuphakamisa imithwalo enzima. Ingaba imoto okanye i-slab ye-concrete, akunandaba, i-jack ye-pneumatic ikwazi ukuphatha nayiphi na umthwalo. Ewe, ngaphandle kokugqithisa imida evumelekileyo yesikhundla somenzi.

Isici

Izixhobo zomoya eziphambene neenqwelo-moya zixhobo eziphathekayo, esekelwe kwizinto ezibonakalayo: i-polym eqhubekayo, isixhobo esixhasayo, umgca womoya kunye nesiphathi. Ukongezelela, ngaphakathi kweso sixhobo kukho iindlela ezininzi eziphakamisa ngokukhawuleza kwezithuthi.

Umgaqo wokusebenza

I-algorithm yesenzo salo sixhomekeke kumgaqo womoya ogxininiswe (ngaphezulu kancinane - igesi). Izigaba zokusetyenziswa kwezi ndlela zilandelayo: Okokuqala, umoya ungena kwinkqubo ngokusebenzisa umgca womoya okhethekileyo kwi-system igcwalisa igumbi eliphambene le sixhobo. Ngelo xesha, uxinzelelo olukhulu ngaphakathi kwindlela, owandisa ama-cushions e-raber. Emva koko bahlenga ngaphantsi kwemoto okanye kwenye indawo, ngokuphakamisa isithuthi. Kwenzeka njani ukuba imoto ihla? Nanku, akukho nto inzima. Ngokufakela iqhosha elifunekayo kwinkqubo, i-valve ekhethekileyo ibangela, kwaye iyanciphisa uxinzelelo oluvela kwinkqubo. Ngaloo ndlela, imoto ibuyela kumavili.

Iinkcukacha zobugcisa

Ingxowa ye-pneumatic ingaba neempawu ezahlukileyo ngokuxhomekeke kwisigaba kunye nohlobo. Ukuqhubela phambili kweli nqanaba, inqanaba lomxinzelelo osebenzayo, olusekwe kwinkqubo, lunokuvela kwi-2 ukuya kwi-9 i-atmospheres, kunye nokuphakama kokuphakama-ukusuka kwi-37.5 ukuya kuma-56 cm. Nangona kunjalo, oko kuhleliyo kuyafana, ngoko ke ukuphakama okufanayo okufanayo (15 cm) kunye nokuhlawula okuphantsi. Ngokuxhomekeke kwimodeli, iifake ze-pneumatic for cars zingaphakamisa izixhobo ezinzima ukusuka kwi-1 ukuya kwi-4 toni. Kuthiwani malunga neengcomo zomvelisi ukuba i-tani yeetoni ezi 4 ingasetyenziselwa ukukhusela iitalta ezinkulu ezinkulu ? Emva kwakho konke, ungayikhohlwa ukuba imithetho ye-physics ayizange ikhanselwe, kwaye ubunzima obwakhiwe kumavili amane emoto, emva kokuphakamisa imoto, isixhobo siwela "emagxeni" ama-3 amathayi kunye nempahla efanayo yokuphakamisa. Ukuze kuqondwe ubunzima bentambo ye- automobile ye- automobile , kwanele ngokwahlula ubunzima bezithuthi ngenani levili. Yintoni ephuma? Umzekelo, ukuba i-tonnage ye-2-axle wagon i malunga ne-7.5 toni, ke i-jack ye-pneumatic enekhono lokuphakamisa ubuncinane ubunzima be-1.875 toni kufuneka ifakwe ukuyiphakamisa. Cinga ukuya kwi-1850 kilogram ngevili, kunye kunye ngokufanayo (mhlawumbi ngeephosiso ezincinane) kwindlela yokuphakamisa.
