submersible wastewater pump

Determine the basic parameters: Flow requirement: Determine the required flow rate of the submersible pump according to the treatment scale and sewage transport volume of the sewage treatment plant. Calculate the amount of sewage to be discharged per hour, and select an appropriate - flow submersible wastewater pump based on this. If there is a need for drainage volume adjustment, the flow variation range under different working conditions also needs to be considered. Head requirement: Measure the vertical height difference from the installation position of the submersible pump to the discharge point, and add factors such as pipeline friction losses and local losses to determine the required head. Ensure that the pump's head can meet the requirement of smoothly transporting sewage to the designated position. Consider the characteristics of the medium: Sewage composition: Analyze whether the sewage contains solid particles, fibers, corrosive substances, etc. If there are more solid particles in the sewage, a submersible pump with good flow - passing ability and anti - clogging performance should be selected. Its impeller should be able to effectively pass a certain multiple of the fiber material of the pump diameter and a large proportion of solid particles. For sewage containing corrosive components, the material of the pump should have corresponding corrosion resistance, such as using stainless steel, engineering plastics and other materials. Temperature range: Understand the temperature of the sewage to ensure that the submersible pump can work normally at this temperature. Some special sewage treatment processes may generate high - temperature sewage. At this time, a chemical resistant submersible pump that can withstand high temperature and chemical corrosion needs to be selected.     Concentration and viscosity: The concentration and viscosity of sewage will also affect the selection of submersible pumps. High - concentration and high - viscosity sewage require pumps with strong transport capacity and motor - carrying capacity, and the price of such submersible pumps will be relatively high.   Evaluate the installation environment:   Submerged depth: Measure the installation depth of the submersible pump in the sewage tank or treatment facility to ensure that the submerged length of the selected pump can meet the requirements. Generally, the submerged depth of the submersible pump has a certain range limit, and an appropriate model needs to be selected according to the actual situation, such as a submersible water pump for well.For example submersible corrosion-resistant pumps.   Space limitation: The spatial layout of the sewage treatment plant may be relatively compact, so the installation space of the submersible pump needs to be considered. Selecting a compact - structured and small - volume submersible water pump can save installation space and facilitate maintenance and inspection.   Surrounding facilities: Check whether there are other equipment or obstacles around the installation position of the submersible pump to ensure that the installation and operation of the pump will not be affected. At the same time, consider the impact of the pump's vibration and noise on the surrounding environment.   Select reliable brands and suppliers:   Product quality: Select submersible pump manufacturers with good product quality and high reliability, which can provide good after - sales service. Information such as word - of - mouth in the industry and user reviews can be referred to.   Supplier's qualifications: The supplier should have good reputation and qualifications, and be able to provide formal product sales and after - sales service. Check the supplier's business license, production license and other relevant certificates to understand its production capacity and technical level.   After - sales service: The submersible pump may malfunction or require maintenance during use, so the supplier's after - sales service is crucial. Ensure that the supplier can provide timely technical support, repair service and spare parts supply.
