The main components of the centrifugal water pump include: impeller, pump shaft, pump casing, pump seat, stuffing box (shaft seal device), leakage reducing ring, bearing seat, etc. Impeller. The impeller is the working part of the centrifugal water pump. It relies on its high-speed rotation to perform work on the liquid to realize the .
Centrifugal pumps are widely used in various industries for fluid transportation and are known for their efficiency and reliability. In this article, we will explore a centrifugal pump example to understand how these pumps work and how to calculate important parameters.
The document contains 5 solved problems related to centrifugal pumps. The problems cover topics like calculating head, power required, efficiency,
Example:
A centrifugal pump has an outlet diameter equal to two times the inner diameter and is running at 1200 rpm. The pump works against a total head of 75 m. We need to calculate the velocity of flow through the impeller.
Solution:
To calculate the velocity of flow through the impeller, we can use the formula:
\[ V = \frac{Q}{A} \]
Where:
- \( V \) = Velocity of flow (m/s)
- \( Q \) = Flow rate (m\(^3\)/s)
- \( A \) = Area of the impeller (m\(^2\))
First, we need to calculate the flow rate using the formula:
\[ Q = \frac{\pi \times D^2 \times N}{4 \times 60} \]
Where:
- \( D \) = Diameter of the impeller (m)
- \( N \) = Pump speed (rpm)
Given that the outlet diameter is two times the inner diameter, we can calculate the diameter of the impeller:
Inner diameter, \( D_i = D \)
Outlet diameter, \( D_o = 2D \)
Area of the impeller, \( A = \frac{\pi}{4} \times (D_o^2 - D_i^2) \)
Substitute the values and calculate the flow rate:
\[ Q = \frac{\pi \times (2D)^2 \times 1200}{4 \times 60} \]
Next, we calculate the area of the impeller:
\[ A = \frac{\pi}{4} \times ((2D)^2 - D^2) \]
Now, we can calculate the velocity of flow using the formula mentioned earlier.
