求翻译：溢流阀不稳定，如由于滑阀与阀孔配合不当或锥阀与阀座接触处被污物卡住、阻尼孔堵塞、弹簧歪斜或失效等使阀芯卡住或在阀孔内移动不灵，引起系统压力波动和噪声。是什么意思？

Relief valve instability, such as the slide valve and the valve hole with the improper or poppet valve with the valve seat at the dirt stuck orifice blockage, spring skew or failure of the spool stuck or in the valve hole does not move spirit, caused by system pressure fluctuations and noise.

Pressure relief valve is not stable, such as the slide valve and the valve hole or cone valve and valve seat, contact with the dirt stuck, Blocking vents are not blocked, and spring, skewed or invalidate the spool or the valve hole in mobile, cause the system pressure fluctuations and noise.
