The accuracy of traditional spectrum analysis for the diagnosis of reciprocating pump valve is not satisfied for the interference of the noise and the vibration of the adjacent parts.
Therefore, regulating valve will produce a strong shock and a harsh noise, resulting in fracture spool quickly.
所以调节阀会产生强烈的震荡并发出刺耳的噪声，因而导致阀芯很快断裂。

Closer throttling, creating higher pressure drops may cause cavitation or excessive velocities which could cause high noise levels, vibration and possible damage to the valve or adjacent piping.
