Maintenance of Submersible Pump with Poor Pumping Effect
Submersible pumps are widely used in domestic and industrial water pumping. They are generally compact, efficient and quieter than ordinary water pumps. However, under certain working conditions, the submersible pump will suddenly fail to work or fail to meet the requirements of the overall pumping effect. This cannot be ignored and must be handled in time. Primarily, careful inspection should be done to identify the problem. Possible causes include excessive pressure in the pipeline, water level fluctuations, and motor overheating.
First, if the pressure in the pipeline is high, it will have a great impact on the normal operation of the submersible pump, causing the water output to be insufficient. To solve this problem, the pressure reducing valve should be adjusted according to the rated flow and pressure parameters of the submersible pump. It should be noted that the pressure should not be too large, so as to avoid the submersible pump running under overload and caused by too large load on the motor, thereby reducing the life of the motor.
Second, the water level in the well will also affect the output of the submersible pump. Submersible pumps are generally long-dip underwater pumps, and their operation is initiated by the pressure of the water itself. If the water level is too low, the submersible pump does not have enough power to push the water, which will reduce the output. The water level fluctuations will also cause changes in the tunnel air pressure, resulting in changes in the output of the submersible pump. In this case, the submersible pump can be restarted after the water level rises, so that the output of the submersible pump can be restored.
Finally, motor overheating is also a common cause of poor pumping effect in submersible pumps. When the overheat protection device built into the submersible pump is activated, the submersible pump may be abnormally stopped or the output is insufficient. In this case, the motor should be inspected to find out the cause of the fault. If necessary, a new motor should be replaced. When replaced, be sure to pay attention to the voltage, power, outlet size and other parameters to ensure that they match the parameters of the submersible pump in order to make the new motor works properly.
In summary, improper operation of the submersible pump may cause poor operation or failure. In this state, a careful inspection should be done to identify the source of the problem. The causes include excessive pressure in the pipeline, water level fluctuations, and motor overheating. Depending on the situation, the necessary maintenance should be done to make sure that it will work properly. If problems are still present, it is important to consider replacing the submersible pump or its motor in order to make sure it runs optimally.
