1.液体内有气体，仔细检查砂泵及进水管路各密封面连接螺栓有否松动，密封垫是否损坏，泵体及管路系统零件有否损坏。

2.管路支撑不稳，水泵底座或地脚螺栓松动是造成振动常见的原因，必须紧固各处螺栓，避免出现松动。

3.砂泵与电机轴不同心，应进行调整，用皮带转动时，转动带过松或接头接触不良，也会引起振动。水泵叶轮不平衡运行中叶轮磨损或个别叶轮流道堵塞易造成振动，有时也因轴弯曲工叶轮不良失去平衡而引起振动。

1. Liquid gas, carefully check the pump and the water inlet pipe of the sealing surface connecting bolts are loose, the sealing gasket is damaged, pump body and the piping system components is not damaged.

2.管路支撑不稳，水泵底座或地脚螺栓松动是造成振动常见的原因，必须紧固各处螺栓，避免出现松动。

2. Instability line support, pump base, or anchor bolts loosening is caused by vibration are common causes, the everywhere fastening bolts must be to avoid loosening.

3.砂泵与电机轴不同心，应进行调整，用皮带转动时，转动带过松或接头接触不良，也会引起振动。水泵叶轮不平衡运行中叶轮磨损或个别叶轮流道堵塞易造成振动，有时也因轴弯曲工叶轮不良失去平衡而引起振动。

3. Pump and motor shaft concentric, should be adjusted, belt rotation, rotating belt too loose or bad connections, caused by vibration. Water pump impeller imbalance in the operation of individual impeller impeller wear or clogging cause vibration, sometimes due to bad impeller axis bending work out of balance caused by vibration.
