UBUKHULU OMKHULU UN UHS U CUP SEAL ROD PISTON SEAL 475*500*22 MM UMBALA OBOMVU Izitywina zeHydraulic

Iimpawu zokutywinwa kwe-polyurethane zishwankathelwa ngolu hlobo lulandelayo:

1. Iimpawu ze-polyurethane zinefuthe elihle lokuthintela uthuli.Ayingenwa lula zizinto zangaphandle, ukuthintela konke ukuphazamiseka kwangaphandle, kunye neoyile encangathi yomphezulu kunye nezinto zangaphandle zinokukhutshelwa kude;

2. Ukumelana nokunxiba okuphezulu kunye nokuchasana okunamandla kwe-extrusion.Iimpawu ze-polyurethane ziyakwazi ukuhamba ngasemva nangaphezulu ngesantya se-0.05m / s kwindawo yoxinzelelo lwe-10MPa ngaphandle kokuthambisa;

3. Ukumelana neoli elungileyo.Iitywina zePolyurethane aziyi kugqwala naxa zijongene neoyile yepetroli efana nekerosene kunye nepetroli, okanye iioyile ezisebenza ngoomatshini ezifana neoyile yehydraulic, ioyile yenjini, kunye neoyile yokuthambisa;

4. Ubomi benkonzo ende.Ngaphantsi kweemeko ezifanayo, ubomi benkonzo ye-polyurethane seals ngamaxesha angama-50 ama-nitrile seals (itheyibhile engezantsi ithelekisa iipropati ze-polyether polyurethane seals kunye ne-nitrile rubber).Ukusuka kwitheyibhile engezantsi, kunokubonwa ukuba izitywina ze-polyether polyurethane zineenzuzo ezininzi ekuxhathiseni ukunxiba, ukomelela, kunye nokuxhathisa ukukrazula.

Ukongeza, ayigqunywanga, ayingenwa lizwi, iyanqanda amadangatye, iyamelana nokubanda, iyamelana nomhlwa, ayifunxanga, kwaye kulula ukuyifaka.

Kubukhulu obukhulu be-polyurethaneamatywina e-hydrauliczenziwe ngezinto zokufakelwa kwemibhobho evela kumazwe angaphandle kwaye zicolwa kusetyenziswa ubuchwepheshe bokuvelisa umngundo.Ke akukho mda wokungunda, umda oqhelekileyo.Udonga oluncinci lunokutshintshwa ngokusekelwe kwimeko yomonakalo jikelele we-cylinder ye-hydraulic, kwaye ukunyamezela kwe-dimensional kunokulungiswa ngokufanelekileyo.Imveliso kunye nokusetyenzwa kobuntu kwaye kufanelekile kwimveliso.Ukongeza, isixhobo sokutywina se-hydraulic esenziwe nge-BD SEALS i-polyurethane imathiriyeli ayikhubazeki ngokulula kwaye inomsebenzi obalaseleyo wokutywina.

1. Ukusebenza kokutywinwa.I-PU impahla ye-hydraulic seal inesiphumo esihle kakhulu sokuchasana nokungcoliswa kwaye ayingenwa lula zizinto zangaphandle, ukuphepha iimpembelelo zangaphandle.Nokuba kukho ukungcola kumphezulu, kunokukhutshelwa ngaphandle

2. Iimpawu zokugaya.Nxiba ukuxhathisa kunye nokuxhatshazwa okunamandla kwe-extrusion.I-polyurethane hydraulic seals inokuhamba emva nangaphezulu ngesantya se-0.05m / s ngaphandle kokumanzisa kwindawo yendalo ye-10MPa yamanzi kunye noxinzelelo;

3. Ukumelana nokugqwesa okugqwesileyo, izinto ze-polyurethane nangona zisetyenziswe kwipetroli.I-oyile yamafutha ekhaphukhaphu okanye ioyile yegiya, ioyile yemoto, izithambisi ezinoomatshini ezifana neoyile yemoto kunye negrisi aziyi konakala;

4. Ukusebenza kwexesha elide.Ngaphantsi komgangatho ofanayo, ubomi bokutywinwa be-hydraulic bezinto ze-polyurethane ziphindwe ngama-50 kwizinto ezisekelwe kwi-nitrile.(Ngezantsi kuthelekiso lokutywinwa koxinzelelo lwamanzi kunye nokusebenza kwe-NBR yezinto eziphathekayo ze-methacrylate polyurethane.) Ukususela kule meko ilandelayo, kunokubonwa ukuba i-methacrylate polyurethane impahla ye-hydraulic seals ineenzuzo ezinkulu ekuxhathiseni ukunxiba, amandla oxinzelelo, kunye nokuphindaphinda.
