MindMap Gallery centrifugal pump
The working principle of a centrifugal pump is to generate centrifugal force by rotating the impeller, accelerate the fluid and bring it into the pump body, and then discharge the fluid through the outlet. The classification and structure of the pump are introduced.

structure
Current-carrying components (conduction transfer energy)
suction chamber
Taper shape: uniform flow rate and small flow loss
Spiral shape: the flow rate is relatively uniform, the flow loss is small, and the head is reduced
Ring shape: uneven flow rate, large flow loss, multi-stage segmented type
Discharge chamber (volute):
Function
1. Collect the liquid and send it to the next level
2. Realize energy conversion and convert speed energy head into pressure energy head
Classification
Spiral shape (low loss, high efficiency)
Ring shape (easy to process with geometric dimensions and excellent surface quality, suitable for multi-stage pumps)
guide vane
Working parts (work done by fluid)
impeller
Impeller form
Closed impeller, clean water pump
Semi-open impeller containing solid particles
Open impeller, containing more solid particles
Double suction impeller, suitable for multi-stage
Blade type
Back-curved blade less than 90 degrees (commonly used)
Small lift
Static energy head ratio is large
The proportion of kinetic energy head is small
Radial blade equal to 90 degrees
Forward curved blades greater than 90 degrees
inducer
Shaft seal device (to prevent leakage)
Orifice ring (leakage in front of impeller, internal leakage)
Single ring type: simple to manufacture, poor effect
Double ring type: widely used
Maze type: complex structure, good effect
Shaft seal (impeller rear shaft end leakage, external leakage)
Packing seal (not suitable for high temperature, high pressure, high speed and strong corrosion)
filler
shaft
stuffing box
Gland
Liquid sealing ring
Mechanical seal (face seal)
Main seals: moving ring, static ring
Auxiliary seals: O-ring, V-ring
Pressing parts: spring, push ring
Transmission parts: spring seat, key, pin, fixing screw
Axial force balancing device (axial force directed towards the suction port of the pump)
Open balance hole
Adopt double suction impeller
Impeller symmetrical installation
Install balance pipe
Install balance plate
Install balance drum
