First, we need to understand what sewage is. Sewage refers to water containing harmful substances after use, including domestic sewage, industrial wastewater, agricultural wastewater, etc. These sewage contains a large number of suspended matter, sediment, organic matter, microorganisms, etc., which has great harm to the environment and human health. Therefore, the work of pumping sewage is crucial. When choosing a sewage pump, the following factors need to be considered:
1. Type: Different types of sewage require different types of pumps. For example, domestic sewage needs to use sewage pumps, while industrial wastewater needs to use chemical pumps.
2. Depth: the pumping depth of the pump needs to match the depth of the sewage, otherwise it will affect the efficiency and life of the pump.
3. Flow: the flow of the pump needs to match the flow of the sewage, otherwise it will affect the efficiency of the pump and the pumping speed.
4. Temperature: Different types of pumps are suitable for sewage at different temperatures. For example, high-temperature sewage requires the use of high-temperature pumps.
5.PH value: Different types of pumps are suitable for sewage with different pH levels. For example, acidic sewage requires the use of acid-resistant pumps.
