B7型活塞密封件
B7型ULTRATHAN®活塞密封是在溝槽中作緊配合安裝的一種唇形密封，B7密封可用于普通橡膠或織物補(bǔ)強(qiáng)橡膠的物理性能達(dá)不到要求的各種場(chǎng)合。
這種密封的主要優(yōu)點(diǎn)是：
● 耐磨性特好。
● 抗擠出。
● 耐沖擊。
● 壓縮變形小。
● 適應(yīng)最苛刻的工作條件。
● 易于安裝。
應(yīng)用范圍：
工作壓力：≤400bar
工作溫度：-35至+110°C
表面速度：≤0.5m/s
介 質(zhì)：液壓油（礦物油基）
主要用于重載行走機(jī)械和靜壓中的活塞密封。
安裝：
這類密封件應(yīng)有軸向間隙（參看表中H和AL欄）。為了避免密封唇口的損壞，安裝時(shí)不要將密封件在銳邊上拉動(dòng)。這類密封通?？裳b入閉式溝槽中。在入口處受到限制時(shí)，可能要使用特殊的安裝工具。用戶若有要求，本公司會(huì)提供這類工具的設(shè)計(jì)方案。
材料：
P5008是邵氏硬度約93A的派克聚氨酯基材料。與目前市場(chǎng)上銷售的其它聚氨酯材料相比，其主要優(yōu)點(diǎn)是耐熱性提高、抗水解能力增強(qiáng)、壓縮變形小。
如有其它特殊要求（壓力、溫度、速度、用于水、HFA液體、HFB液等介質(zhì)中），請(qǐng)與本公司的咨詢服務(wù)部聯(lián)系，以便向您推薦合適的材料和結(jié)構(gòu)。
