As the original design of 750/80 hydraulic gyration crusher was unreasonable,the friction tray could easily deviate from the hydraulic cylinder due to centrifugal force caused by rotation and could rub the upper lining to leave a severe hidden trouble when it was working.
由于750/80液压旋回破碎机的液压缸设计不合理,在运行过程中,液压缸里的中摩擦盘因转动产生的离心力使其偏离球面定位而甩出,并碰擦上衬套而出现故障。
补充资料：超高压
超高压
一般指高于一万大气压的压强。在超高压下，物质的物理化学性质发生显著变化。利用超高压和高温可使物质结构改变，或者合成自然界尚未发现过的物质，如固体氮和性质极硬的氮化硼等。
