Care must be taken so that a shaft will not receive an excess
torque load in multiple pump applications.
Since multiple pump applications up to four (4) have been
done, various points could receive higher loads than they
can transmit
To check for overload all the torques at actual load must
be:
1. Compared to the load rating of each input shaft
2. the sum of all units must not exceed the first pump's torque
rating
To calculate the actual input torque use the following formula:
TA = TR * ( PA / PR ) *
(% Stroke / 100%)
Where:
TA=Actual torque, PA=Actual maximum pressure, TR=Rated torque,
PR=Rated working pressure |
