(3)液压冲击产生的噪声

先导式溢流阀在卸荷时，会因液压回路的压力急骤下降而发生压力冲击噪声。愈是高压大容量的工作条件，这种冲击噪声愈大，这是由于溢流阀的卸荷时间很短而产生液压冲击所致在卸荷时，由于油流速急剧变化，引起压力突变，造成压力波的冲击。压力波是一个小的冲击波，本身产生的噪声很小，但随油液传到系统中，如果同任何一个机械零件发生共振，就可能加大振动和增强噪声。所以在发生液压冲击噪声时，一般多伴有系统振 动。CTR3-075/P2.2/GP1-0074/B10N

介质在节流阀瓣和阀座之间流速很大，以致使这些零件表面很快损坏－即所谓气蚀现象。为了尽量减少气蚀影响，阀瓣采用耐气蚀材料（合金钢制造）并制成角为140～180的流线型圆锥体，这还能使阀瓣能有较大的开启高度，一般不在小缝隙下节流。CTR3-050/M3A/GP2-0158/D00N

(2)输出压力过高

若回路负载持续上升，泵的压力也持续上升，当属正常。若负载一定，泵的压力过负载所需压力值，则应检查泵以外的液压元件，如方向阀、压力阀、传动装置和回油管道。若大压力过高，应调整溢流阀。CTR0-008/P0.37/1P-1.6R/B01G
