混流泵五大常见问题及解决办法

以协助大家更好的运用混流泵 提供工作效率。
1、传动轴或电机轴承过热 产生缘由：短少光滑油或轴承决裂等。 处理方法：加注光滑油或改换轴承.
 
2、混流泵不出水 产生缘由：泵体和吸水管没灌满引水； 动水位低于水泵滤水管；吸水管决裂等。 处理方法：扫除底阀毛病，灌满引水； 降低水泵的装置位置，使滤水管在动水位之下， 或等动水位升过滤水管再抽水；修补或改换吸水管。
3、混流泵功率耗费过大 产生缘由：水泵转速太高； 水泵主轴弯曲或水泵主轴与电机主轴不同心或不平行； 选用水泵扬程不适宜；水泵吸入泥沙或有梗塞物；电机滚珠轴承损坏等。 处理方法：检查电路电压，降低水泵转速； 矫正水泵主轴或调整水泵与电机的相对位置； 选用适宜扬程的水泵；清算泥沙或梗塞物；改换电机的滚珠轴承。
4、混流泵泵体猛烈振动或产生噪音 产生缘由：水泵装置不牢或水泵装置过高； 电机滚珠轴承损坏；水泵主轴弯曲或与电机主轴不同心、 不平行等。 处理方法：装稳水泵或降低水泵的装置高度； 改换电机滚珠轴承； 矫正弯曲的水泵主轴或调整好水泵与电机的相对位置。
5、混流泵流量缺乏 产生缘由：影响水泵流量缺乏多是吸水管漏气、 底阀漏气；进水口梗塞；底阀入水深度缺乏； 水泵转速太低；密封环或叶轮磨损过大；吸水高度超标等。 处理方法：检查混流泵吸水管与底阀，堵住漏气源；清算混流泵进水口处的淤泥或梗塞物；底阀入水深度必需大于进水管直径的1.5倍，加大底阀入水深度；检查电源电压， 进步水泵转速，改换密封环或叶轮；降低水泵的装置位置，或改换高扬程混流泵。 假如您遇到其他混流泵产品运用问题不能处理，不论能否是购置的我们的产品，都欢送你来电咨询，以便我们把混流泵做的更好。


To help people better use the mixed flow pump to provide work efficiency.
1. Causes of overheating of transmission shaft or motor bearing: lack of lubricating oil or bearing rupture, etc. Solution: add lubricating oil or replace the bearing
2. Causes of mixed flow pump failure to discharge water: the pump body and suction pipe are not fully filled with water; The dynamic water level is lower than the water pump filter pipe; Broken suction pipe, etc. Solution: remove the fault of bottom valve and fill the water with water; Lower the installation position of the water pump so that the filter pipe is below the dynamic water level, or wait for the dynamic water level to rise before pumping the water from the filter pipe; Repair or replace the suction pipe.
3. Causes for excessive power consumption of mixed flow pump: the pump speed is too high; The water pump spindle is bent or the water pump spindle is not concentric or parallel with the motor spindle; Improper pump lift; The water pump sucks sediment or has blockage; The motor ball bearing is damaged. Solution: check the circuit voltage and reduce the pump speed; Correct the main shaft of the water pump or adjust the relative position between the water pump and the motor; Select water pump with appropriate lift; Remove sediment or blockage; Replace the ball bearing of the motor.
4. Causes of severe vibration or noise of mixed flow pump: the pump is not installed firmly or the pump is installed too high; The motor ball bearing is damaged; The water pump spindle is bent or not concentric or parallel with the motor spindle. Solution: install the water pump stably or reduce the installation height of the water pump; Replace the motor ball bearing; Correct the bent water pump spindle or adjust the relative position of water pump and motor.
5. Causes for insufficient flow of mixed flow pump: insufficient flow of water pump is mainly caused by air leakage of suction pipe and bottom valve; The water inlet is blocked; Insufficient water depth of bottom valve; The speed of water pump is too low; Excessive wear of sealing ring or impeller; The water absorption height exceeds the standard. Solution: check the suction pipe and bottom valve of the mixed flow pump to block the air leakage; Clean up the sludge or blockage at the water inlet of the mixed flow pump; The water inlet depth of the bottom valve must be greater than 1.5 times the diameter of the water inlet pipe, and the water inlet depth of the bottom valve shall be increased; Check the power supply voltage, increase the water pump speed, and replace the sealing ring or impeller; Lower the installation position of the water pump, or replace the high lift mixed flow pump. If you encounter problems with other mixed flow pump products that cannot be solved, no matter whether you purchased our products or not, you are welcome to call us for advice, so that we can make the mixed flow pump better.
