What size are the torque bolts?
US Recommended Bolt Torque
| Size | Recommended Torque | |
|---|---|---|
| Grade 2 | Grade 5 | |
| 7/8″ | 129 | 355 |
| 1″† | 188 | 541 |
| * Sizes from #4 to #10 are in lb-in. Sizes from 1/4″ up are in lb-ft. † Fine thread figures are for 1″-14. Grade 2, 5, and 8 values are for slightly lubricated bolts. |
What angle do you use for torque?
Torque Calculation The direction of the torque is given be the right hand rule, which gives a vector out toward the reader in this case. Note that the torque is maximum when the angle is 90 degrees.
How is the torque speed of a pump determined?
Like pumps, motors produce a torque-speed curve of their own. By overlaying the torque-speed curve of a pump and a motor, one can verify that the motor is producing enough accelerating torque to drive the pump to full speed, as shown below. In this overlay the shaded area reflects the accelerating torque available from the motor to drive the pump.
How much torque does a centrifugal pump need?
To overcome pump inertia and static friction, approximately 20% of full load torque is required. As the pump’s speed increases, the required torque gradually declines. For example, at about 15% full load speed the required torque typically is around 5% or 10% full load torque. As shown below, the pump torque-speed curve follows the square law:
