Pressure bearing problem of horizontal centrifugal pump body
Thread Content
Central air conditioning circulation pump. The water slowly flows from the outlet to around the 26th floor. Then go directly from the 26th floor to the entrance. The inlet pressure reaches 14-15 kg when working. I used a cast iron pump before, and when the inlet valve was opened, the pump body burst before it was started. The maximum working pressure does not exceed 16 kg. I'm a little scared now. I would like to ask the forum buddies. I am now replacing the cast iron cast iron for my client. Can it withstand such working pressure? What I'm worried about now is that after replacing the pump body, it still won't be able to withstand such great pressure. And the water pressure at the pump outlet cannot press the floor so high. Water pump inlet 150 outlet 125
Unless the pipeline is forced to be installed, ductile cast iron can generally withstand less than 4MPa. Unless there is a casting defect.
There is no mandatory installation of pipes. Originally the pump body was cast iron. Not ductile iron. The pressure is 16 kg

Think about it: How much pressure can malleable iron valves generally bear?
I can guess where this pump is produced. There are no cast ties outside the pump body. The casting model steals the shape and reduces the weight.
This problem is an equipment quality issue and can be solved directly with the equipment manufacturer. Haha, you get what you pay for.
The designed outlet pressure of this pump is greater than or equal to 1.6MPA.
If it were me, I would switch to cast steel and specialize in high-temperature and high-pressure pump design.
The manufacturing quality is not a matter of the materials used, just ask the manufacturer for compensation!
