Working principle of geothermal well booster pump
The working principle of geothermal well booster pump is mainly based on the effect of centrifugal force. The following is a detailed explanation of the working principle of geothermal well booster pump:
1. Basic working principle
Liquid suction:
Before the booster pump starts working, the suction pipe and the pump must be filled with liquid.
When the pump starts, the impeller starts to rotate at high speed, and the liquid rotates with the blades.
Liquid throwing:
Under the action of centrifugal force, the liquid is thrown away from the impeller and ejected outward.
The ejected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases.
Liquid discharge:
The liquid with increased pressure is discharged from the pump outlet and enters the pipeline system.
Forming a vacuum low-pressure zone:
At the blades, because the liquid is thrown to the surroundings, a vacuum low-pressure zone with neither air nor liquid is formed.
The liquid in the liquid pool flows into the pump through the suction pipe under the action of the air pressure on the pool surface, forming a continuous suction and discharge process.
2. Boosting process
Liquid kinetic energy increases:
When the impeller rotates at high speed, it exerts a force on the liquid to generate lift.
The liquid thus gains energy and increases its kinetic energy, thereby achieving pressurization.
Pressure regulation:
In practical applications, the working pressure of the booster pump can be adjusted by adjusting the pump speed, changing the impeller diameter, or adjusting the valve in the pipeline system.
3. Application scenarios
The geothermal well booster pump is mainly used in the development and utilization of geothermal energy, including hot springs, heating systems, etc. In addition, it can also be used in the fields of extracting domestic water from deep wells, urban and industrial water supply and drainage, agricultural irrigation and drainage, garden sprinkler irrigation, and seawater lifting.
4. Precautions
Maintenance:
Regularly maintain the booster pump, check the wear of components such as impellers and bearings, and replace damaged components in time.
Clean the pump body and pipeline system to prevent blockage and corrosion.
Safe operation:
When operating the booster pump, the relevant safety operating procedures should be followed to prevent accidents.
Ensure the sealing of the pump body and pipeline system to prevent liquid leakage.
In summary, the geothermal well booster pump throws out the liquid and increases its pressure through the action of centrifugal force, thereby achieving the purpose of pressurization. During use, attention should be paid to maintenance and safe operation to ensure its normal operation and extend its service life.
