Vortex pump piping

When vortex pumps are connected in parallel, the design of the piping inlet and outlet must follow these principles: 1. Balance the flow rate: Ensure that each vortex pump receives an adequate supply of water flow to enable it to perform at its best. In parallel operation, the water inlet pipe can be connected directly to the inlet of each vortex pump, ensuring that all pumps receive an equal flow rate. 2. Pressure balance: Balance the outlet pressures of each vortex pump to ensure that they can share the load evenly when operating in parallel. Pressure balance can be achieved by installing pressure regulating valves or check valves at the outlet of each vortex pump. 3. Avoid backflow: Prevent backflow problems caused by improper piping design, that is, flow from the outlet of one pump to the inlet of another pump. Backflow can be prevented by using appropriate valves, stop valves, and pressure relief valves. 4. Consider parallel operation: Depending on actual needs, the inlet and outlet can be designed to operate in parallel, allowing each vortex pump to be turned on and off simultaneously to meet flow requirements under different load conditions. In summary, the piping design for parallel vortex pumps requires taking into account factors such as flow rate, pressure, and backflow in order to ensure the proper operation and efficient performance of the parallel system. It is recommended to consult a professional engineer or supplier before designing the piping system, in order to develop an appropriate plan based on the actual conditions. .
