Shaft Input (Shaft Torque) Limitation

Shaft torque limitations of triple pumps are shown in the table. Please ensure that
the total of the maximum load of the three pumps do not exceed the torque limit
shown in the table. Please calculate shaft torque from the operating speed and shaft
input.
N: operating speed (min-1) Shaft Torque Limitation
Model Code
L: shaft input sum (kW) N·m
Shaft torque: T = (60 × 1000/2πN) × L = (9554/N) × L (N·m) SQP211 360
(Example) S  QP432-60-38-14, operating speed 1200 min-1, first pump 14 MPa,
SQP311 610
second pump 17.5 MPa under max. load,
First pump shaft input: from table on page B1-5, SQP4-60 shaft input is SQP321 610
57.1 kW SQP421 950
Second pump shaft input: from table on page B1-5, SQP3-38 shaft input SQP431 950
is 36.2 kW SQP432 950
Third pump shaft input: from table on page B1-4, SQP2-14 shaft input is
18.4 kW
Shaft input sum: L = 57.1 + 36.2 + 18.4 = 111.7 (kW)
Shaft input sum substituted for torque in the table,
Shaft input torque: T = 9554 × 111.7/1200 = 889.3 (N·m)
Thus, the shaft torque is below the limitation of 950 N·m for SQP432
Please confirm shaft torque using this procedure.
