May I ask if a check valve can be installed on the pipeline from the storage tank to the pump inlet? Prevent liquid from other suction inlets of the pump from flowing back into the storage tank
A check valve is generally not installed in the section from the storage tank to the pump inlet, as this can affect the pump’s suction capacity; check valves are instead installed on the pump outlet pipeline to prevent liquid from flowing back and causing the pump impeller to rotate in the reverse direction, which could lead to loosening. For pumps that are installed slightly above the sink, a bottom valve can be installed at the bottom of the inlet pipe; this is also a type of check valve, and its purpose is to ensure that the pipe is filled with liquid.
To prevent liquid from other suction inlets of the pump from flowing back into the storage tank; he was referring to the liquid from those other suction inlets. It seems to mean that multiple pipelines feed into one pump...
Generally, it depends on the type of pump; if it is a piston pump, a check valve can be installed at the pump outlet.
Yes, it’s the situation you mentioned.
I’m not quite familiar with this; you can refer to the comments above – they’re very professional
I haven’t seen that before; after all, in practice, different substances are not pumped using the same pump. The same pump can feed two containers, but both are controlled by manual valves.
The branches should be equipped with valves, and it shouldn’t be possible to draw fluid from several branches at the same time; no additional components are needed
I’ve never seen a check valve installed at the pump inlet; generally, a check valve is located at the pump’s outlet. Regarding the issue you mentioned, is the pipe between the inlet and outlet of the pump quite long? If it doesn’t grow, the volume of the different materials is roughly the same in these two cases; changing the valve to switch materials simply results in a slight difference in volume. Since the volumes are similar, why not place it at the outlet? Moreover, installing it importally will affect the pump’s suction volume and thus its performance
