The Correct Arrangement Of The Sewage Pump Helps To Exert Its True Effectiveness

The sewage pump uses the speed pulse of water. The impeller drives the pump impeller to pump the water to the embankment. Due to its easy use, it is widely used in the industry.Correct layout helps the pump to truly achieve its effectiveness. Let’s learn about its correct layout method.　　1. The design flow rate of the suction pipe is generally 1.0-1.5m/s, and the low flow rate shall not be less than 0.7m/s.To remove the air accumulated in the straw, the horizontal portion of the straw should be slightly raised along the direction of the water flow and the slope of the pipe can be 0.005.When it is necessary to gradually reduce the connection between the suction pipe and the water pump, an eccentric head should be used.2. When two or more sewage pumps share a water outlet pipe, each pump's outlet pipe should be equipped with a valve, and a check valve should be set between the valve and the water pump; if the water pump uses a separate water outlet pipe and the flow rate is free, a check valve cannot be set up, so it should be installed in the horizontal section as much as possible to prevent dirt from precipitating on the valve.3. The flow rate of the sewage pump outlet pipe is generally not less than 1.5m/s.When two or more pumps share one outlet pipe and only one pump works, the flow rate should not be less than 0.7m/s to avoid deposition in the pipe.When the pump's outlet pipe is connected to the main outlet pipe (connection pipe), it shall not be connected from the bottom of the main pipe to avoid precipitation in the pump's outlet pipe when the water is pumped out.4. Each self-priming pump of the suction pipe should be equipped with a separate suction pipe and should be shorter as much as possible to improve hydraulic conditions, reduce head loss, and reduce the possibility of impurities blocking the pipeline.5. For self-filling water pumps, the valve should be installed on the suction pipe for maintenance.If the sewage pump is not automatically filled, a vacuum pump or water sprayer should be used to start the pump and the bottom valve is not allowed to be placed on the suction pipe because the bottom valve can easily clog the sewage, which will affect the start of the pump and increase the head loss and power consumption.
