Look at the problem with the piping of this pump
Thread Content
This is a modified pool of the company, which contains steam condensate and a small amount of oil-containing chilled water (ethylene glycol). A liquid level gauge with liquid level interlock controls a pipeline centrifugal pump. The pump inlet and outlet diameters are both DN25. Let’s take a look at the piping problems of this pump. It is best to list the basis in the standard and learn together * Making progress together I have made several mistakes. Chemical Equipment and Machinery
This U-shaped bend is a bit powerful. . . Can this pump be turned on?
This U-shaped pipe is a bit confusing. My understanding is that the U-shaped pipe is used to store water so that the pump does not need to be filled next time. But I don’t know if there is a one-way shower head installed at the bottom of the suction port. If not, the pump will shut down due to siphoning when it stops, and the water will not be stored. Also, should we add a one-way valve to the outlet of this pump? Would it be better to add a filter to the suction inlet of the pressure gauge pump? Add a purge port at the lowest outlet?
The inlet pipeline is too long, and the U-shaped bend in the inlet pipeline will cause the pump to be unable to load.
You said it very comprehensively. Are there any other problems with the inlet U-shaped pipe?
It works, and there is no problem with the flow rate, but the pipes are strange.
Both inlet and outlet piping use DN25 pipes. According to management, the inlet pipe should be one or two levels larger to prevent cavitation and effectively control flow. However, since it is required to pump condensate water, it may not need to be so high to drain the water.
This U-shaped bend is to keep water in the pump at all times, right?
I don’t know if the water pipe has a bottom valve, otherwise the water in the pump will not be retained.
