品牌:<\/span> 瑞典特瑞堡TRELLEBORG（原寶色霞板<\/span>Busak+Shamban<\/span>）<\/span> <\/span><\/p>品名:<\/span> 德國<\/span>佐康 威士密封圈 Zurcon Wynseal<\/span> <\/span><\/p>說明<\/span> <\/span><\/p> 佐康威士密封圈是一種活塞雙向作用的密封元件，它由一個(gè)特殊聚氨酯材料制成的密封環(huán)和一個(gè)作為施力元件的<\/span>O<\/span>形圈組成。這種密封件的獨(dú)特性能來自于它的特殊的截面設(shè)計(jì)。兩個(gè)外側(cè)的密封唇作為主密封，以密封來自于系統(tǒng)一側(cè)的液體壓力，同時(shí)可防止在整個(gè)密封工作面上形成液壓力積聚，降低了竄漏風(fēng)險(xiǎn)。位于密封面中間的支撐圈以及兩側(cè)密封唇的凸起邊緣提高了比壓，增強(qiáng)了密封效果。位于密封溝槽兩側(cè)的密封面由于采用了特殊形狀設(shè)計(jì)，可使系統(tǒng)壓力作用于<\/span>O<\/span>型圈，從而使其被激活。這樣就可以保證整個(gè)工作過程中系統(tǒng)壓力直接作用在整個(gè)密封件上。<\/span><\/p>由于佐康威士密封圈與特康格來圈具有相同的溝槽尺寸，所以特別適用于使用量大、密封效率高、能滿足不同工況需要且成本相對較低的標(biāo)準(zhǔn)液壓缸中使用。必須注意的是，在這種情況下必須檢查間隙尺寸。<\/span><\/p> <\/p> 優(yōu)點(diǎn)<\/span><\/p>- <\/span>靜態(tài)和動態(tài)密封效果好；耐磨性好；溝槽結(jié)構(gòu)簡單，整體式活塞；溝槽符合<\/span>ISO 7425<\/span>。<\/span><\/p> <\/p> 技術(shù)數(shù)據(jù)<\/span><\/p>壓力<\/span>: <\/span>≤ <\/span>25 MPa <\/span>(<\/span>Z20N<\/span>)<\/span><\/p>≤ <\/span>40 MPa <\/span>(<\/span>Z05N/WUAGN<\/span>)<\/span><\/p>速度<\/span>: <\/span>≤ <\/span>0.5 m/s<\/span><\/p>溫度<\/span>: -35<\/span>℃<\/span>至<\/span>+110<\/span>℃<\/span><\/p>介質(zhì)<\/span>: <\/span>礦物<\/span>液壓<\/span>油<\/span><\/p> <\/p> 材料<\/span><\/p>標(biāo)準(zhǔn)材料：<\/span><\/p>威士密封圈： 佐康<\/span> Z20 <\/span>邵氏<\/span> <\/span>A 93 <\/span>(<\/span>要求邵氏<\/span> <\/span>A 96<\/span>，使用<\/span>Z05<\/span>)<\/span><\/p>O<\/span>形圈<\/span>: <\/span> <\/span>NBR<\/span>橡膠，邵氏<\/span> <\/span>A70<\/span><\/p>組件代號<\/span>: <\/span> <\/span>Z20N/ <\/span>或<\/span>Z05N<\/span><\/p>Sealing Parts<\/span>（密封件）參考型號：<\/span><\/p>密封圈<\/span>: <\/span> <\/span>聚氨酯橡膠，<\/span> <\/span>邵氏<\/span> <\/span>A 96<\/span><\/p>O<\/span>形圈<\/span>: <\/span> <\/span>NBR<\/span>橡膠，邵氏<\/span> <\/span>A 70<\/span><\/p>組件代號<\/span>: <\/span> <\/span>WUAGN<\/span><\/p> <\/span>
