Vertical centrifugal pump usage situations
Thread Content
Our factory uses a vertical centrifugal pump to pump out the condensate water in the rehydrator. Is it okay to use a horizontal centrifugal pump? Does anyone have information on this?
Can't. This is not an ordinary horizontal centrifugal pump, but a hot well pump. In fact, it is quite simple. The pump shaft seal is a packing seal. Because the sealing surface is perpendicular to the ground, water can be poured on the horizontal sealing surface to prevent air from leaking into the pump body and causing the vacuum to increase.
I heard from my master that the medium temperature transported by the vertical centrifugal pump is relatively high. Using a vertical pump can increase the inlet pressure and prevent cavitation. Is this the friend on the 2nd floor?
A horizontal centrifugal pump can also be used for the steam turbine. The horizontal centrifugal pump used in my unit is as follows.: 6N6, 4N6, CC32-250, etc.
True vertical centrifugal pump: Equipped with speed increasing box, small flow rate and high lift. Comes with auxiliary oil pump.
The poster's expression was not very clear. There are also many types of vertical centrifugal pumps, such as vertical high-speed pumps, vertical pipeline pumps, vertical submersible pumps, vertical deep well pumps, vertical fire pumps, vertical condensate pumps, vertical liquid sulfur pumps, vertical cryogenic pumps, etc. What the poster is talking about should be a vertical condensate pump, also called a vertical condensate pump. Its characteristic is that the pump must have a low cavitation margin and is mainly used to transport condensate with low device cavitation margin. If the NPSH of a horizontal pump with the same flow rate and lift is equal to or lower than that of a vertical condensate pump, it can be used instead, but the installation space should be considered.
