Principle and operation of Jet pump

6 of 44

Types of jet pump

Deep well

Advantages

  • Easy maintenance.
  • Long service life.
  • It can install away from the water source.

​

Disadvantages

  • Only submersible pumps can use for higher suction heads.

​

​

7 of 44

Shallow well

Advantages

  • Simple machine, almost maintenance-free.
  • A shallow well pump is inexpensive.

​

Disadvantages

  • These have cavitation issues.
  • These pumps have priming problems.

​

Applications

  •  Technology and are often using in chemical laboratories to produce vacuum. 
  • Liquid jet solids pump :Liquid jet solids pumps are based on proven jet pump.
  • Technology and are often used to transfer types of solids.
  • Deep well jet pump withdraw from depth 45m.
  • Shallow well jet pump withdraw from depth 25m.

Two phase flow jet pump

​

Shows the liquid flow through a pipe with gas bubbles and ends with a gas flow with liquid droplets.

​

11 of 44

Shows the liquid and gas flow merged and almost equal in volume.

12 of 44

Shows a liquid flow with only gas bubbles and vice versa gas flow and liquid droplets.

Aim and objective

  • Change in jet pump position to different levels then take data.

​

  • Change speed of the motor by changing the frequency of the inverter.

​

  • To prove when level increase the mass flow rate change.
