Discussion on the outlet valve of shielded pumps
Thread Content
Our factory has a shielded pump used to transport materials containing small solid particles. Due to the low opening degree of the outlet valve, it gets worn out after operating for some time, requiring replacement. The processing process is rather complicated. If the outlet valve is opened wide, the pump will experience overcurrent. Is there any way to open the outlet valve wide without causing the pump to overload?
Yes, choose a pump with a lower head: lol. You have chosen a pump head that is too high
Operating at a low opening degree for a long time is actually not good either.
Provide information 1: parameters required for the pump to operate actually; 2: pump curve; 3: medium density
It is not advisable to operate the pump for extended periods at its minimum designed flow rate; cavitation can occur in such cases
Choose another design with a lower flow rate or a smaller diameter for the impeller
Add a concentric reducer and use a valve with a smaller diameter
