Eyona nto isetyenziswa ngokuqhelekileyo imathiriyeli yerabhaamatywina e-hydraulicyirabha ye-nitrile NBR.Ukongezelela, xa kukho iimfuno ezikhethekileyo zokumelana nokushisa kunye nokuchasana kweoli, i-fluororubber ingasetyenziswa;Xa kukho iimfuno ezikhethekileyo zokuxhatshazwa kokugqoka kunye nokuxhatshazwa koxinzelelo, i-AU / EU (i-polyurethane rubber) inokukhethwa.
1. Iintlobo zemidiya esebenzayo yokutywinwa kwe-hydraulic
Ingaba indawo yokusebenza ye-hydraulic seals engamanzi okanye yigesi?Ukuba ilulwelo, ukuhambelana phakathi kolwelo kunye nezinto eziphathekayo kufuneka kuthathelwe ingqalelo;Igesi nayo kufuneka ithathele ingqalelo ukuhambelana kwezixhobo kunye ne-lubricant kunye negrisi;Ukutywinwa kwegesi kunye noxinzelelo olubi kufuneka kwakhona kuthathele ingqalelo ukuphefumla.Ukuba izinto zokutywina ziyahambelana nolwelo lokutywinwa, lunokubangela ukuba into yokutywina yandise okanye ikhontrakthi, ekhokelela ekungaphumelelini kwinqanaba lokuqala lokusetyenziswa.Ukwandiswa kwetywina kubangela ukwanda kokumelana nokukhuhlana kwaye kubangela ukuba itywina iqengqeleke.Ukucutheka kwento yokutywina kunokubangela ukuhla kokulayishwa kwangaphambili, ukuncipha komthamo wembuyekezo ye-eccentricity, kwaye ekugqibeleni ikhokelele ekuvuzeni.
2. Ukutywinwa okunamandla okanye okumileyo
Amatywina aDynamic aneemfuno ezihambelanayo zokukhuhlana kunye nokunxiba ukusebenza kwezinto, kunye nezixhobo ezinee-coefficients zokukhuhla ezifanelekileyo kufuneka zikhethwe ngokusekelwe kubukhulu besantya sokunyakaza.Ukuze ufezekise ubomi obaneleyo benkonzo, kuyafuneka kwakhona ukuba ukhethe ukuchasana nokugqoka kwezinto ezisekelwe kwisantya kunye nokubetha kwentshukumo.Xa kukho imfuneko yokusebenza kwesantya esisezantsi, ingqwalasela ekhethekileyo kufuneka ihlawulwe kubungakanani be-friction coefficient yezinto eziphathekayo kunye nokwahlukana phakathi kwe-coefficients eguquguqukayo kunye ne-static friction.
3. Uhlobo lolwakhiwo lwento yokutywina (ikhutshiweyo okanye imilebe emile)
Umgaqo wokusebenza wokutywinwa uyahluka kunye neentlobo ezahlukeneyo zesakhiwo, ezifuna ngokungenakuphepheka iimpawu ezahlukeneyo zoomatshini ezifana ne-elasticity, amandla, kunye nesantya sokuguqulwa kwezinto.
4. Ubushushu obusebenzayo betywina le-hydraulic
Uluhlu lweqondo lokushisa olusebenzayo lweerubha zokutywina ezahlukeneyo kunye neeplastiki zihluka kakhulu.Xa ukhetha izinto eziphathekayo, kuyimfuneko ukuqonda ngokuchanekileyo ukushisa okusebenzayo kwamacandelo okutywinwa, ngokukodwa indawo yokushisa ephantsi apho amacandelo akhoyo, kwaye ukhethe izinto ngokufanelekileyo;Okanye lawula ukunyuka kwamaqondo obushushu amacandelo, iinkqubo, kunye netywina ngokusekelwe kuluhlu lobushushu obusebenzayo bezinto eziphathekayo.Khetha izinto ezinokumelana nobushushu bazo obuphezulu.
- Uxinzelelo lokusebenza lwezitywina ze-hydraulic
Uxinzelelo olusebenzayo luyi-parameter ephambili yokusebenza kwe-hydraulic kunye ne-pneumatic systems, enokuthi ihluke phakathi kwe-1-400MPa okanye uluhlu olukhulu.Ukuxhatshazwa koxinzelelo lwezinto kufuneka kuhambelane neemfuno zoxinzelelo lokusebenza.
6. Ngaba indawo yokusebenza ye-hydraulic seals ingcolisekile Ukuba kukho ukungcoliseka kothuli kwindawo yokusebenza, kuya kwandisa ukuguga kwezinto eziphathekayo, kunye nokuxhatshazwa kwempahla kufuneka kuphuculwe. iimeko, izinto eziphathekayo kufuneka zibe ne-elasticity eyaneleyo ukuhlawulela ukungonelanga ukunyanzeliswa koqhagamshelwano lokutywinwa okubangelwa ukufuduka okubangelwa yi-vibration.
