Rotary Airlock Valve Capacity Calculator

Formula

The formula to calculate the rotary airlock valve capacity is:

\[ C = \frac{R}{D} \div \left( \frac{E}{100} \right) \div S \]

Where:

\(C\) is the rotary airlock valve capacity (volume)
\(R\) is the rate of conveying (units per minute)
\(D\) is the product density (units per volume)
\(E\) is the valve efficiency (%)
\(S\) is the rotor speed (RPM)

What is a Rotary Airlock Valve Capacity?

A rotary airlock valve capacity is the total amount of product that a rotary feeder can move through an opening per unit of time. It is a crucial parameter in the design and operation of rotary airlock valves, ensuring efficient and accurate material handling.

Example Calculation 1

Let's assume the following values:

Rate of Conveying (R) = 100 units/min
Product Density (D) = 2 units/volume
Valve Efficiency (E) = 85%
Rotor Speed (S) = 50 RPM

Using the formula:

\[ C = \frac{100}{2} \div \left( \frac{85}{100} \right) \div 50 \approx 1.18 \]

The rotary airlock valve capacity would be approximately 1.18.

Example Calculation 2

Let's assume the following values:

Rate of Conveying (R) = 200 units/min
Product Density (D) = 3 units/volume
Valve Efficiency (E) = 90%
Rotor Speed (S) = 60 RPM

Using the formula:

\[ C = \frac{200}{3} \div \left( \frac{90}{100} \right) \div 60 \approx 1.23 \]

The rotary airlock valve capacity would be approximately 1.23.
