General Instructions:
Direction of the forces and torques:
Fx ...Force in direction of the x-axis (pump shaft)
Fy ...Force in direction of the y-axis
(perpendicular to the x-axis)
Fz ...Force in direction of the z-axis
(perpendicular to the x-axis)
Mx ...Torque around the x-axis
My ...Torque around the y-axis
Mz ...Torque around the z-axis
The suction and pressure joints must be considered
separately.
If not all loads in effect reach the value limits, one of
these loads may exceed the usual value limit by 1.4
times. The following requirement must be observed
here:
