What Is a Jet Pump?
A jet pump is a device that employs a fluid or steam jet to create negative pressure for suctioning material. Similar to an aspirator or ejector, it mixes the operating fluid with the target fluid to achieve high pressure, making it particularly effective for applications requiring high pressure but lower flow rates.
Applications of Jet Pumps
Jet pumps are versatile, and used in applications ranging from recirculation systems in nuclear reactors to well water extraction due to their compact design and ability to achieve the high pressures necessary for deep wells.
Features of Jet Pumps
Advantages
- Compact size with superior suction power compared to centrifugal pumps.
- Capable of suctioning water from depths up to 20 meters, ideal for well applications.
- Enhances crop quality and yield through three-dimensional growth support.
Disadvantages
- Operational noise and high energy consumption.
- Less suitable for use during disasters due to reliance on electricity.
Types of Jet Pumps
Differentiated by their suction heights and applications, jet pumps cater to both shallow and deep well needs, with variations such as injectors for high discharge pressure and ejectors for handling both gases and liquids.
How to Select Jet Pumps
- Suction Height: Choose based on the water source’s depth.
- Noise Level: Opt for quieter models if noise is a concern.
- Power Output: Select according to water usage, with 250W-400W models common for home use.
How to Use Jet Pumps
Jet pumps work in tandem with shallow or deep well pumps, typically servicing depths of 8 to 20 meters. Regular maintenance of the jet section and timely replacement of parts like the accumulator and switch ensure longevity and efficiency.
