Can the liquid in the horizontal tank be pumped out?
Thread Content
May I ask, for the horizontal tank in the picture, can the liquid inside be pumped out when the tank is evacuated? Thank you all first!
This requires calculating the pressure difference to determine it
It can work; choose a larger net positive suction head, or increase the vertical distance between the bottom of the tank and the pump inlet. These decisions should be based on the actual conditions, taking into account the level of vacuum present
The liquid inside the tank can be pumped out
As long as the vacuum of the entire system is balanced, there is no problem with shooting it out. If the vacuum level inside the tank is higher than the pump’s suction power, it’s not possible to pump fluid out. If it’s lower than the pump’s suction power, then pumping is possible, but it will be slow; once the vacuum level inside the tank becomes higher than the pump’s suction power, pumping will no longer be possible.
Thank you for your reply! Centrifugal pumps operate by utilizing the vacuum created by centrifugal force ； I’m not sure what kind of pump is used for vacuuming; could you provide some more detailed information?
Thank you for your reply! Since there is no actual equipment yet, it’s not known what the vacuum level is, but a rotary vane pump is being used ； The tank is filled with water at room temperature, and the height difference between the liquid level in the tank and the pump inlet is 1.5 meters.
Thank you for your reply! The actual equipment setup isn’t available yet; only the vacuum pump has been selected, which is a rotary vane vacuum pump that can achieve a high level of vacuum.
