How to choose the right pump for sewage treatment?

In the actual production and operation of China sewage treatment plants, the pump does not run in the high-efficiency area, the energy consumption is large, and its control mode is relatively lagging.Due to the complexity of industrial sewage water quality, the requirements for water pumps are more stringent. The requirements for the optimization and selection of water pumps in industrial sewage treatment industry are summarized as follows:
(1) reasonably determine the flow Q and head H values of working conditions, and strictly control the operating point of the water pump within the efficient zone.
(2) in the deviation from the rated condition, the pump can still ensure normal and efficient work.
(3) the pump motor can withstand long-term full load operation.For maximum protection of the motor, in case of accidental overload operation, assuming the cable is damaged and the motor is still underwater, no wet steam from the cable inlet enters the motor or the junction box.
Sewage treatment plant commonly used pumps are sludge filter pump, sewage pump, sewage treatment filter press pump, etc
Water pump is in the sewage treatment plant is the most basic part of all the facilities, water pump energy consumption at the same time also is in the sewage treatment plant energy consumption more, can be seen from the above two aspects are the pump selection is essential to the sewage treatment plant, water pump can run efficiently directly affect the efficiency of wastewater treatment of sewage treatment plant and operation cost, three is Paramount:
1. Pipeline configuration. Reasonable pipeline configuration can reduce backflow and reduce unnecessary hydraulic loss.
2, the efficiency of the pump itself, the main factors affecting the efficiency of the pump is impeller, flow channel, environmental pump impeller is designed by professional engineers, low friction, low resistance, in the energy saving industry first-class.
3, water pump supporting motor, motor power and pump shaft power matching is the key to ensure the flow head,GUANGYI pump in this aspect of the detailed data analysis, the motor and water pump perfect matching.
Selection of pumps for industrial sewage treatment plants
(1) to strengthen the optimization of pump selection;
(2) combining the advanced and efficient energy-saving technologies such as frequency conversion, optimization combination and sewage source heat pump, and then carrying out energy-saving technical transformation for the pump equipment, so as to achieve the goal of energy saving and consumption reduction;

(3) it is necessary to consider the corrosion resistance and acid-base resistance of the pump, because the water quality of industrial sewage is complex, with high suspended matter content, strong acid and alkali characteristics.
