CHEMCO Exit Exam • Set 6 Question 12 of 30

Why the cargo pump in the Framo cannot be overloaded?

✓

Direct Answer

Option B: The pressure of hydraulic oil to the motor driving the cargo pump is designed in such a way that, the pump runs at the optimum speed

Framo pump motors are driven by hydraulic oil. The system's pressure regulation ensures the motor operates at an optimal speed, preventing overload and maintaining efficient cargo transfer, a design feature crucial for pump longevity and safe operation.

All Options

A
The pressure of hydraulic oil to the motor driving the cargo pump is designed in such a way that, the flow is always kept constant
B
The pressure of hydraulic oil to the motor driving the cargo pump is designed in such a way that, the pump runs at the optimum speed (Correct Answer)
C
The pressure of hydraulic oil to the motor driving the cargo pump is designed in such a way that, when the pump over speeds, the flow of oil is reduced
D
The pressure of hydraulic oil to the motor driving the cargo pump is designed in such a way that, the pressure can run the pump at 75% of the capacity

Detailed Explanation & Context

Framo pump motors are driven by hydraulic oil. The system's pressure regulation ensures the motor operates at an optimal speed, preventing overload and maintaining efficient cargo transfer, a design feature crucial for pump longevity and safe operation.
