二、性能與用途
DAS組合封是一個密封及導向元件只需一個溝槽的整體密封。裝入封閉式溝槽,每個活塞用一個。緊湊的密封結(jié)構(gòu)使活塞(油缸)總長度較短,降低了加工成本并有著極佳的抗間隙積壓性能。工作時彈性體不會扭轉(zhuǎn),有著合理的泄漏一減少摩擦。主要用于活塞及液壓缸的密封。如:推土機、挖掘機、裝載機、起重機、液壓閘門及農(nóng)業(yè)機械等。
三、材質(zhì)
A彈性體----丁晴橡膠
B支承環(huán)----尼龍或聚氨酯
C導向環(huán)----尼龍或聚甲醛
四、工礦條件
溫度:-30℃~+120℃
最大工作壓力:35MPa
最大運動速度:0.5m/s
介質(zhì):石油基液壓油、難燃液壓油、環(huán)保液壓油
