Industry knowledge

AFP submersible sewage pump manufacturer details the design features and anti-clogging technology of the AFP submersible sewage pump impeller

Impeller design features:
On the basis of the original closed impeller, open single-blade, double-blade and multi-blade impellers have been added. This design enables the impeller to handle larger solids and long fibers, ensuring anti-clogging performance, which well makes up for the shortcomings of closed impellers in traditional sewage pumps that are prone to clogging.
The open single-channel swept impeller combined with the larger suction inlet allows all materials in the sewage to pass through, further reducing the risk of blockage.
The swirl impeller design allows the pump to minimize the risk of clogging within an acceptable range of efficiency loss when handling large solid particles.
Anti-clogging technology:
The submersible sewage pump itself has strong cutting ability. Its impeller is made of special materials and structural design, which can cut debris in front of the pump, such as fibers, hair, etc., to avoid clogging and damaging the pump body.
A carbon steel anti-sewage box can be installed at the inlet pipe of the submersible sewage pump, and the angle is 45 degrees. A filter is used in the box to filter impurities to further prevent blockage.
After each use of the submersible sewage pump, use high-pressure water to flush the pump body and water pipes. When flushing has no effect, the remaining media can be removed by tapping, but the force must be appropriate.
Optimization parameters: It is recommended to use different rotation speeds according to different specific gravity media. In media with high concentration and high solid content, appropriately reducing the rotation speed can slow down the wear of the impeller and reduce the risk of clogging.
Dilution medium: When a part of the medium has a high viscosity, you can add water to the medium to dilute the viscosity of the medium to prevent clogging.

AFP submersible sewage pump manufacturer explains the heat dissipation technology and measures of AFP submersible sewage pump in high temperature environment

Natural heat dissipation method:
Principle: Cooling the submersible sewage pump through the natural heat transfer of water. This method does not require the assistance of other equipment and is relatively easy to implement.
Implementation measures: Ensure that the submersible sewage pump is designed with sufficient heat dissipation area in order to effectively dissipate heat through the natural convection of water.
Water circulation cooling method:
Principle: Add a radiator inside the submersible sewage pump and dissipate heat through water circulation. Water circulates inside and outside to achieve the purpose of cooling.
Implementation measures: Integrate water circulation system and radiator into the design of submersible sewage pump. Water circulation pipes and other related equipment may need to be installed to ensure effective water circulation and heat dissipation.
Highly efficient motors and drives:
Principle: Using high-efficiency motors and drives can reduce the energy consumption and heat generation of submersible sewage pumps.
Implementation measures: Choose high-efficiency, low-energy-consumption motors and drives, and ensure that they match other parts of the submersible sewage pump.
Thermal protection system:
Principle: By integrating a thermal protection system, the temperature of the submersible sewage pump can be monitored and automatic protection measures can be taken when necessary.
Implementation measures: Install a temperature sensor in the submersible sewage pump and connect it to the control system. Once the temperature exceeds the set value, the control system will automatically shut down the submersible sewage pump or take other appropriate protective measures.
Ventilation and cooling units:
Principle: In some cases, manufacturers may equip submersible sewage pumps with ventilation and cooling devices to further reduce temperatures.
Implementation measures: This may include installing a cooling fan or fins on the submersible sewage pump housing to increase air flow and heat dissipation.
