Is the pump’s inlet a siphon tank?
Thread Content
There is a tank at the inlet of the pump, and below that tank is an underground water tank. Is this tank a siphon tank? What is the principle behind setting it up? Thank you, extra points. As shown in the figure
It is a siphon tank; the centrifugal pump is used for pumping liquid. Before starting the pump, the siphon tank is filled with water, which enables self-priming.
Calling it an energy-storing sensation would be more appropriate, right? Siphon? ? :)
Ensure that there is sufficient fluid at the inlet of the pump when starting it, to prevent vacuum conditions and ensure proper flow

The pump draws water from an underground tank; the inlet pipe is inserted into the tank near the bottom, and a bottom valve is installed at the inlet (acting as a check valve). When starting a centrifugal pump, the pump chamber must be filled with water. Before the first start-up, both the inlet and outlet valves of the pump should be opened, and water should be added to a small tank (the pipe at the top of the tank serves as the water inlet). Once water begins to flow out as the exhaust valve at the pump outlet opens, it indicates that the pump chamber is filled. At that point, the outlet valve should be closed and the pump started; once pressure builds up, the outlet valve can be opened. In the future, after stopping the pump and then restarting it, if the pump is shut down for an extended period of time, there is a risk that the bottom valve may leak; or when the pump is under maintenance and all water inside the pump chamber has been drained, the same steps must still be repeated when starting the pump. If the pump is to be shut down for a short period, it can be started directly. The opening on the upper side of the small tank is likely an overflow port; the overflow pipe must be inserted into the pool, right? Does the small tank have a level gauge? I couldn’t see clearly
The picture doesn’t show everything; it’s not possible to see the entire tank, as well as all the pipelines and other accessories and their routes! There is no drain at the pump inlet! Is it the valve or the filter near the pump at the inlet?
The combination of tank and pump acts as a self-priming pump
