Installation distance of centrifugal pump
Thread Content
How much does the installation distance between the two pumps affect them? I have a pump here that vibrates heavily and has insufficient outlet pressure; could it be due to its proximity to other components, and is that causing cavitation?
At the very least, it should be easy to take over and maintain
Putting aside the difficulties of maintenance for now, will this cause each pump to draw in insufficient water, thereby leading to cavitation vibration?
If the inlets are connected in parallel to a single pipe, this situation will occur with the pumps that follow. If it is a circulating water pump, it will not do so when there is an adequate amount of water in the tank.
Actually, you can take a look at the photos I sent. These three pumps are connected in parallel to a tank with a diameter of 4 meters. One of them experiences significant vibration, and its outlet pressure is much lower than that of the other two pumps; therefore, I suspect cavitation is the cause
Three pumps, with two in use and one as a backup. According to what you’ve said, there should be no issues with the imported ones. The problem might lie in the outlets; the parallel connection of the outlets causes the flow rate of some pumps to decrease.
I think it’s caused by the liquid flowing off the main inlet pipe, thereby reducing the flow rate; is the suction inlet of the pump, which experiences high vibration and low outlet pressure, located at the end section?
Check the pump with low outlet pressure to see if the inlet pipe filter is clogged, and whether the inlet eccentric reducer is installed correctly
Is it really necessary to have two active units and one backup? By specifying two units with high bandwidth, and using one active unit along with one backup unit, there will be no competition for bandwidth
The outlet pipes lead to different devices, so I now think there’s a problem with the pump (the impeller) or there’s an obstruction at the inlet
For four-meter tanks, the demand is likely to be significant going forward. What’s the situation with the filters?
