USIZI OMKHULU UN UHS U CUP SEAL ROD PISTON SEAL 475*500*22 MM UMBALA OBOMVU Ama-Hydraulic Seals

Izici ze-polyurethane seal zifinyezwa ngale ndlela elandelayo:

1. Izimpawu ze-polyurethane zinomphumela omuhle wokuvimbela uthuli. Ukungangenwa kalula yizinto zangaphandle, ukuvimbela konke ukuphazamiseka kwangaphandle, ngisho nowoyela onamathelayo ongaphezulu nezinto zangaphandle zingasulwa;

2. Ukumelana nokugqoka okuphezulu kanye nokumelana okuqinile kwe-extrusion. Izigxivizo ze-polyurethane zingahamba ziye emuva naphambili ngesivinini esingu-0.05m/s endaweni yokucindezela engu-10MPa ngaphandle kokugcotshwa;

3. Ukumelana nowoyela okuhle. I-polyurethane seal ngeke igle ngisho nalapho ibhekene namafutha kaphethiloli njengophalafini nophethiloli, noma amafutha ayimishini afana nowoyela wehydraulic, uwoyela wenjini, namafutha okugcoba;

4. Impilo ende yesevisi. Ngaphansi kwezimo ezifanayo, impilo yesevisi ye-polyurethane seals iphindwe izikhathi ezingu-50 kune-nitrile seal (ithebula elingezansi liqhathanisa izakhiwo ze-polyether polyurethane seals ne-nitrile seal). Kusukela kuthebula elingezansi, kungabonakala ukuthi ama-polyether polyurethane seal anezinzuzo eziningi ekuphikisweni kokugqoka, amandla, nokumelana nokukhala.

Ngaphezu kwalokho, ayivamisile, ayizwani nokuzwakala, ayinqandeli ilangabi, imelana nokubanda, ayingeni ekugqwaleni, ayimunyi, futhi kulula ukuyifaka.

Ukuze uthole usayizi omkhulu we-polyurethaneama-hydraulic sealszenziwe ngezinto ezifakwa ngaphandle kwamapayipi futhi zigaywe kusetshenziswa ubuchwepheshe bokukhiqiza isikhunta. Ngakho-ke awukho umkhawulo wesikhunta, umkhawulo ojwayelekile nje. Udonga oluncane lungashintshwa ngokusekelwe esimweni somonakalo jikelele we-hydraulic cylinder, futhi ukubekezelelana kwe-dimensional kungahlelwa ngokunengqondo. Ukukhiqizwa nokucutshungulwa kwenziwa ngabantu futhi kuwufanele umkhiqizo. Ngaphezu kwalokho, i-hydraulic sealing device eyenziwe nge-BD SEALS polyurethane material ayikhubazeki kalula futhi inomsebenzi omuhle kakhulu wokuvala.

1. Ukusebenza kokubeka uphawu. I-PU material hydraulic seal inomphumela omuhle kakhulu wokulwa nokungcolisa futhi ayingenwa kalula izinto zangaphandle, igwema amathonya angaphandle. Ngisho noma kukhona ukungcola phezulu, kungakwanwa

2. Izici zokugaya. Ukumelana nokugqoka kanye nokumelana okunamandla kwe-extrusion. Ama-polyurethane hydraulic seals angaya emuva naphambili ngesivinini esingu-0.05m/s ngaphandle kokumanzisa endaweni yemvelo engama-10MPa amanzi nokucindezela;

3. Ukumelana nokugqoka okuhle kakhulu, izinto ze-polyurethane ngisho nalapho zisetshenziswa kuphethiloli. Uwoyela ongasindi kaphethiloli noma uwoyela wegiya, uwoyela wezimoto, izinto zokuthambisa eziyimishini ezifana nowoyela wezimoto namafutha ngeke kugqwale;

4. Ukusebenza kwesikhathi eside. Ngaphansi kwesimo esifanayo esivamile, ukuphila kokuvaleka kwe-hydraulic kwempahla ye-polyurethane izikhathi ezingu-50 kunezinto ezisekelwe ku-nitrile. (Ngezansi ukuqhathaniswa kokuvalwa kwengcindezi yamanzi kanye nokusebenza kwe-NBR kwempahla ye-methacrylate polyurethane.) Kusukela kulesi simo esilandelayo, kungabonakala ukuthi i-methacrylate polyurethane material hydraulic seal inezinzuzo eziphawulekayo ekuphikisweni kokugqoka, amandla okucindezela, kanye nokubopha kabusha.
