Are there two pumps for oil inlet and outlet in the oil tank, or just one pump?
Thread Content
The 350-cubic-meter plant oil tank in the factory needs inlet and outlet pumps; I’m not sure how to install them Should it be equipped with one unit that has both inlet and outlet functions, or two units? Also, could you provide a brief explanation of the working principle of a unit that has both inlet and outlet functions? Thank you so much!
Some positive-displacement rotor pumps can be reversed, allowing the inlet and outlet positions to be swapped, such as peristaltic pumps. Moreover, the flow rate of such pumps is generally not very high; a flow rate of a few dozen cubic meters would be considered good.
It still depends on your own needs. The most basic requirement is that if the flow rates and head requirements for filling and emptying the tank are similar, it is possible to use one pump ； If the difference is large, it’s better to use different pumps.
Are the flow rates and parameters of the inlet pump and the outlet pump the same? If it’s possible, a pump that can be used in either inlet or outlet mode can be employed; the advantage is cost savings. However, wear and tear over time increases, so it is recommended to use two pumps – this way, if one pump fails, there is another one available as a replacement, preventing disruptions in operation
For pumps that can be used for both inflowing and outflowing oil, it is best to have one in use and one as a spare as well.! The specific design depends on the scale of your quantity! ! !
If the height of the oil tank is much lower than the pump’s head, it can still be used by making the return pipeline higher
