Analysis of the reasons for the drop in pressure of the submersible pump

Submersible pumps are common devices widely used in agricultural irrigation, industrial water circulation, and other scenarios. However, during use, there may be issues with pressure drop. Below are several main reasons for the pressure drop in submersible pumps.

1. Damage or blockage of the pump impeller

The impeller is the core component of the submersible pump. If the blades are damaged or severely worn, it can lead to a decrease in the pump's flow rate, resulting in a pressure drop. Additionally, if the pump is blocked by impurities, it can also reduce the pump's working efficiency and cause a pressure drop.

2. Pipeline system issues

Leaks or blockages in the pipeline system can also lead to a pressure drop in the submersible pump. Aging, damage, or loose connections in the pipeline can cause leaks, affecting the pump's output pressure. At the same time, sediment or impurities in the pipeline may also cause blockages, hindering water flow and reducing pressure.

3. Power supply or motor issues

The motor of the submersible pump is its power source. If the motor voltage is unstable or if there is a fault in the motor itself, such as a short circuit in the winding, it can lead to a decrease in the pump's speed, thereby affecting the output pressure.

4. Insufficient submersion depth or overload operation

Insufficient submersion depth may lead to inadequate environmental pressure for the submersible pump, affecting its normal operation. Overload operation can cause the internal mechanical components of the submersible pump to bear excessive pressure and workload, leading to decreased performance and significant pressure loss.

5. Improper operation and maintenance

In daily use and maintenance, improper operation may also lead to a pressure drop in the submersible pump. For example, not cleaning, checking, or replacing worn parts for an extended period can affect the pump's performance. Additionally, inappropriate selection and usage environment may also cause the submersible pump to experience pressure drops during actual use.

The reasons for the pressure drop in submersible pumps include damage or blockage of the pump impeller, pipeline system issues, power supply or motor issues, insufficient submersion depth or overload operation, and improper operation and maintenance. To address these issues, we need to take appropriate measures for repair and maintenance to ensure the normal operation and stable performance of the submersible pump. At the same time, during actual use, it is also important to choose the appropriate model and usage environment to ensure the pump can perform effectively.
