23. What is the difference between single stage pump and multistage pump?
24. What types of bearings are used in a pump?
25. What will happen to bearing, if it
21. What is use of Euler's equation in pumping?
Pump transferring mechanical energy to liquid flowing and losses.
This energy conversation process is calculated by Euler's equation.
22. Why do we use lubricating oil system in a centrifugal pump? What are the safe guarding systems of a centrifugal pump?
Lubricating oil system is to remove heat from pump bearings
Safe guarding systems of a centrifugal pump
- Pre-warning alarms (Unit Alarms)
- Trip switches
- Safety relief valves
- Seal pot level high low alarms
23. What is the difference between single stage pump and multistage pump?
Single stage pump has only one impeller and multistage pump has two or more impellers
24. What types of bearings are used in a pump?
Sleeve bearings and ball bearings are used in pump.
25. What will happen to bearing, if it
