Newly installed pump foundation
Thread Content
The foundation of the newly installed pump in our company (which has been installed) has sunk by 5 mm at one end – the end where the motor is located. We’re not sure if this will affect its performance. It’s a large multi-stage water pump with a power rating of 1000 Kw. This post was last edited by zjgjjx on 2009-3-25 at 17:42
It should have an effect on the pump; the level of the pump will change. It should be aligned first, and grouting should be done after that
As mentioned above, it will affect the proper operation of the pump, mainly the pump equipment itself. It has no effect on head, flow rate, etc. It’s better to deal with the basics first. I believe just reinstalling and leveling it out isn’t enough. The foundation needs to be processed again
It will reduce the pump’s service life, and it also causes wear on the mechanical seal and the pump shaft.
It will certainly affect the operation of the pump; if the foundation continues to sink, it will increase the external force exerted by the pipes on the pump, having a fatal impact on it. First, it is necessary to confirm that the foundation is no longer sinking; thereafter, the foundation should be treated again, the pump should be reinstalled and aligned, and then piping should be connected for use.
This is very dangerous; it’s necessary to rebuild the foundation.
Continue observing; it’s not sinking, so just install the leveling device. If there is further settlement, reinforcement solutions need to be studied.
It will certainly affect the operation of the pump. We are now investigating the cause of the foundation settlement, reinforcing the foundation, then reinstalling and aligning the pump before connecting the piping for use.
There must be an impact; first, we need to find the cause. It is processed for various reasons. Generally, the foundation is treated first by reinforcing it; if that doesn’t work, the foundation has to be rebuilt.
