Problems with pipeline installation for newly installed centrifugal pumps
Thread Content
Two vertical pipeline centrifugal pumps were installed as part of the company’s renovation project; let’s take a look at any issues with the piping Can the observant netizens spot the problems? Chemical equipment and machinery
There is no pressure gauge at the outlet; there is a problem with the inlet pipe, and cavitation may occur
The Y-type filter is too low, making it difficult to remove the filter element for cleaning

It seems that there is a large difference in diameter between the pump and the pipes, and support should be added to the outlet pipe (near the rubber gasket).
Also, the pump motor is a non-explosion-proof motor
It will be very troublesome to service the inlet filter in the future. It is also better to install a short circuit between the inlet valve and the filter.
This is a water pump, right? The error is similar to the ones mentioned earlier; I just don’t understand why piping work shouldn’t be done after the foundation is ready ? ?
Valves placed before the inlet filter should not be butterfly valves, as these make it impossible to clean the filter.
The pipe fittings are connected directly to the flat welding flanges, with concentric reducers being used for tees. The filter cannot be removed; no tee is used, and there is no drain port
Firstly, the diameter of the inlet piping is unreasonable; the filter elements cannot be removed for maintenance, there is no drainage system to prevent freezing, and there are no pressure gauges, etc
