Oomatshini bokwakha abanakwahlulwa kwiisilinda zeoyile, kwaye iisilinda zeoyile azinakwahlulwa kwiitywina.Isitywina esiqhelekileyo yindandatho yokutywina, ebizwa ngokuba yi-oil seal, edlala indima yokwahlula ioli kunye nokuthintela ioli ukuba ingaphumi okanye idlule.Apha, umhleli woluntu loomatshini ukuhlelele ezinye iintlobo eziqhelekileyo kunye neefom zamatywina e-cylinder.
Iimpawu eziqhelekileyo zeesilinda ze-hydraulic zezi ntlobo zilandelayo: i-dust seals, i-piston rod seal, i-buffer seal, amakhonkco okuxhasa isikhokelo, i-end cover cover kunye ne-piston seal.
Umsesane wothuli
Iringi yothuli ifakwe ngaphandle kwesigubungelo sokugqibela se-hydraulic cylinder ukuthintela ukungcola kwangaphandle ukuba kungangeni kwi-cylinder.Ngokwendlela yokufakela, inokwahlulwa ibe luhlobo lwe-snap-in kunye nohlobo lokucinezela.
Iindlela ezisisiseko ze-snap-in dust seals
Itywina lothuli lwe-snap-in lolona luxhaphakileyo.Njengoko igama libonisa, isitywina sothuli sibambekile kwi-groove kudonga lwangaphakathi lwesivalo sokuphela kwaye sisetyenziswa kwiimeko ezingentle zokusingqongileyo.Izinto eziphathekayo ze-snap-in dust seal ngokuqhelekileyo ziyi-polyurethane, kwaye isakhiwo sineenguqu ezininzi, ezifana ne-H kunye ne-K cross-sections ziyi-double-lip structures, kodwa zihlala zifana.
Ezinye iinguqu ze-snap-on wipers
I-wiper yohlobo lwe-press-in isetyenziswa phantsi kweemeko ezinzima kunye nezinzima-umsebenzi, kwaye ayibambekanga kwi-groove, kodwa umaleko wesinyithi usongelwe kwizinto ze-polyurethane ukwandisa amandla, kwaye icinezelwe kwi-cover yokugqibela ye-hydraulic. isilinda.Iitywina zokucinezela uthuli nazo ziza ngeendlela ezahlukeneyo, kubandakanya umlebe omnye kunye nomlebe ophindwe kabini.
Piston intonga itywina
Itywina yepiston, ekwabizwa ngokuba yi-U-cup, yeyona nto iphambili yepiston yetywina kwaye ifakwe ngaphakathi kwesiciko sesiphelo secylinder yehydraulic ukuthintela ukuphuma kweoyile yehydraulic.Umsesane wokutywina wepiston wenziwa nge-polyurethane okanye irabha ye-nitrile.Kwezinye iimeko, kufuneka isetyenziswe kunye neringi yenkxaso (ekwabizwa ngokuba yi-back-up ring).Iringi yenkxaso isetyenziselwa ukuthintela umsesane wokutywina ukuba ungacudi kwaye ukhubazeke phantsi koxinzelelo.Iitywina zentonga zikwafumaneka kwiintlobo ezininzi.
Isithinteli setywina
Izitywina zeCushion zisebenza njengetywina lesibini intonga ukukhusela intonga yepiston ekunyukeni ngequbuliso kuxinzelelo lwenkqubo.Zintathu iindidi ze-buffer seal eziqhelekileyo.Uhlobo A sisitywina esineqhekeza elinye elenziwe nge-polyurethane.Iintlobo ze-B kunye ne-C zimbini-ezimbini ukukhusela i-extrusion yesitywina kunye nokuvumela isitywina ukuba simelane noxinzelelo oluphezulu.
isikhokelo ring inkxaso
Ikhonkco lokuxhasa isikhokelo lifakwe kwikhava yokuphela kunye nepiston ye-hydraulic cylinder ukuxhasa intonga yepiston kunye nepiston, ukukhokela i-piston ukuba ihambe ngendlela echanekileyo, kwaye inqande ukudibanisa isinyithi ukuya kwintsimbi.Izinto eziphathekayo ziquka iplastiki, ubhedu olufakwe kwiTeflon, njl.
Isitywina sokugqiba
Umsesane wokutywina wokuvala isiphelo usetyenziselwa ukutywina i-cylinder end cover kunye nodonga lwesilinda.Luphawu olumileyo kwaye lusetyenziselwa ukuthintela ioyile yehydraulic ukuba ingavuzi kwisithuba esiphakathi kwesivalo sokuphela kunye nodonga lwesilinda.Ngokuqhelekileyo iqulethe irabha ye-nitrile i-O-ring kunye ne-back-up ring (ukugcina iringi).
Piston itywina
Itywina lepiston lisetyenziselwa ukwahlula amagumbi amabini ecylinder yehydraulic kwaye lelona tywina kwicylinder yehydraulic.Ngokuqhelekileyo iziqwenga ezibini, iringi yangaphandle yenziwe nge-PTFE okanye inayiloni kunye neringi yangaphakathi yenziwe ngerabha ye-nitrile.Landela iiNjineli zoomatshini ukuze ufumane ulwazi olongezelelekileyo ngoomatshini.Ukwahluka kukwakhona, kubandakanywa ne-Teflon-coated bronze, phakathi kwabanye.Kwiisilinda ezibambeleyo, kukwakho neekomityi ezimilise okwe-U ye-polyurethane.
