A turbine water pump works by using rotating impellers to draw water in and then direct it outwards into a diffuser, increasing its pressure and flow.
Here's a more detailed explanation of the process:
Components of a Turbine Water Pump
A typical vertical turbine pump includes:
- Motor: Provides the power to rotate the impeller.
- Discharge Head: Connects the pump to the piping system and directs the water flow.
- Impeller(s): Rotating component(s) attached to a shaft that draws water in and accelerates it.
- Shaft: Connects the motor to the impeller(s), transmitting rotational force.
- Bowl (Diffuser Casing): A stationary component surrounding the impeller. Its purpose is to slow the high-velocity water exiting the impeller and convert kinetic energy into pressure energy.
- Suction Bell: A bell-shaped inlet at the bottom of the pump that allows water to enter.
Operational Steps
-
Water Entry: The process begins with water entering the pump through the suction bell. This bell-shaped inlet is designed to efficiently guide water into the impeller.
-
Impeller Rotation: The motor turns the shaft, which rotates the impeller(s). As the impeller spins, it creates a centrifugal force.
-
Water Acceleration: The rotating impeller blades push the water outward, increasing its velocity and kinetic energy.
-
Diffusion and Pressure Increase: The high-velocity water exiting the impeller enters the bowl (diffuser casing). The diffuser's widening passages gradually slow the water down. This reduction in velocity converts the kinetic energy into pressure energy. This process is based on Bernoulli's principle.
-
Discharge: The pressurized water is then directed upwards through the discharge head and into the connected piping system for its intended use (e.g., irrigation, water supply).
Key Functions Summarized:
| Component | Function |
|---|---|
| Suction Bell | Efficiently draws water into the pump. |
| Impeller | Imparts kinetic energy to the water through rotation. |
| Diffuser (Bowl) | Converts kinetic energy of the water into pressure energy, increasing the overall pressure of the water flow. |
In essence, a turbine water pump converts electrical energy (from the motor) into kinetic energy (via the impeller) and then into pressure energy (via the diffuser), effectively moving water from a lower level to a higher one or increasing its pressure for various applications.
