Joaloka likarolo tse nyane tsa lihlahisoa tse ngata, mechini le lisebelisoa, litiiso li phetha karolo ea bohlokoa.Haeba u khetha tiiso e fosahetseng, mochine oohle o ka senyeha.Ho bohlokoa ho tseba mofuta o mong le o mong oa thepa ea 'nete haeba u batla ho sebelisa tse nepahetseng.Kahoo o ka fumana tiiso ea boholo bo nepahetseng ka litiiso tsa thepa tse loketseng tse ipapisitseng le silindara eo u e sebelisitseng.
Joang ho khetha tiiso e nepahetseng?Ka kopo tsepamisa maikutlo ho moralo oa tiiso le khetho ea thepa.
Ntho ea pele ke mocheso, lisebelisoa tse ling li ka sebelisoa maemong a mocheso o phahameng haholo, tse ling ha li khone.Mohlala, mocheso oa mocheso oa tšebeliso ea tiiso ea PU o tloha ho -35 ho isa ho +100 degree, mocheso oa tšebeliso ea lisebelisoa tsa NBR o tloha ho -30 Celsius ho ea ho +100 degrees Celsius, mocheso oa tšebeliso ea viton material seal o tloha ho -25 Tekanyo ea Celsius ho +300 Celsius.Kahoo ho hanyetsa mocheso ka tiiso e fapaneng ea thepa ho fapane.
Ntlha ea bobeli ke maemo a khatello, litiiso tse ling ha li khone ho sebetsa maemong a khatello e phahameng.U hloka ho tseba mefuta e mengata ea khatello ea tsamaiso ea mokelikeli o sebetsang, hammoho le makhetlo a mangata le ho teba ha litlhōrō tsa khatello.Lits'ebetsong tse ngata, o hloka ho tseba tlhoko ea tiiso ho latela likhatello tsa konkreite.
Ntlha ea boraro ke mokelikeli le viscosity e sebelisoang tsamaisong, litiiso tseo re li sebelisitseng li hloka ho ema ho metsi kapa ho thibela maro a fetang.Re lokela ho hlahloba hore na mecha ea litaba ke diminerale oli thehiloeng kapa metsi thehiloeng.
Kahoo pele u khetha thepa kapa mofuta oa tiiso, etsa bonnete ba hore u tseba hantle hore na ke maro afe a tla be a le teng tsamaisong, mocheso o ka bang teng, le hore na ho ka ’na ha e-ba le khatello e kae.
Ntle le moo, o hloka ho tseba litekanyo tsa tiiso kapa li-diameter tsa piston ea rod, boholo ba groove joalo-joalo, 'me tšebeliso ea silinda le eona ke tlhahisoleseling ea bohlokoa.
A na u na le lipotso mabapi le litlhaloso tse fapaneng tsa tharollo ea hau ea tiiso?Ka kopo ikopanye le rona, litiiso tsa INDEL li tla u fa tataiso ea litsebi.
