Centrifugal Pump System Diagram Analysis.
This diagram illustrates the complete working components and flow path of a centrifugal pump system.
A. Here's a detailed breakdown:
1. Hydraulic Heads
hₛ (Suction head): Vertical distance from water source to pump centerline
2. h_d (Delivery head): Vertical distance from pump centerline to discharge point
3. Flow Path Components
Suction Side:
a. Water sump: Liquid source
b. Strainer: Filters debris
c. Foot valve: One-way valve preventing backflow
d. Suction pipe: Carries liquid to pump
e. Suction flange: Connection point at pump inlet
4. Pump Components:
a. Eye of impeller: Central inlet where liquid enters
b. Impeller: Rotating component that imparts energy
c. Casing: Contains the impeller and guides liquid flow
5. Delivery Side:
a. Delivery flange: Connection point at pump outlet
b. Delivery valve: Controls flow rate/pressure
c. Delivery pipe: Carries pressurized liquid
6. Overhead water tank: Typical destination/storage
B. Working Principle:
1. Liquid is drawn from the sump through the suction pipe (primed by the foot valve)
2. Enters the pump at the impeller eye
3. The rotating impeller increases the liquid's kinetic energy
4. The casing converts this kinetic energy to pressure
5. Pressurized liquid exits through the delivery system to the tank
