Centrifugal pump impeller cutting
Thread Content
The company’s impellers are all cast based on their maximum outer diameter, and there is a large amount of empirical data available for different impeller outer diameters. Now that the customer has specified the actual operating conditions (Q, H), I use these conditions to find the curve in the empirical database that is closest to them, and then proceed with cutting the impeller accordingly. I would like to ask how to verify the shaft power after cutting, and to check whether the motor used still meets the requirements
Someone please answer! Where are the sea friends?
Be patient; the sea friends don’t have time to come and take a look yet
The shaft power after cutting is calculated using the new parameters
After cutting, check what the efficiency is, and then calculate it based on the parameters specified by the user
After cutting, the power of the shaft is an approximate value; by using a motor paired with an inverter and operating it at different speeds, this value can be determined
