High-speed pump alignment
Thread Content
The motor drives the high-speed pump with 8,000 revolutions per minute (the high-speed pump uses a three-stage gear reduction system). Finding the correct answer is whether we must do it within ten attempts.
0.1mm is a bit low; I’m not sure what type of coupling it is – it should be handled in accordance with the instructions provided for that coupling
Find what is necessary within 0.10. Rotational speed ≥ 3000: Stiffness ≤ 0.02, Elasticity ≤ 0.04
Find what is necessary within 0.10. Rotational speed ≥ 3000: Stiffness ≤ 0.02, Elasticity ≤ 0.04
The speed before the increase should not be high; if the equipment’s installation instructions specify that a value within 0.1 MM is acceptable, then that is fine.
3 should be safe; I guess it’s a flexible connection, a disc coupling.
The disk standard is 0.08 mm for the end face and 0.15 mm radially; of course, our company requires 0.05 mm for the end face and 0.1 mm radially
It’s such an expensive item, be sure to take good care of it.
9th floor, please issue the pump maintenance order!
Some companies require just 5 tests; in reality, the deviation for those 5 tests is equivalent to 10 tests in terms of numerical values, so the requirement isn’t high at all and it’s completely achievable.
The general requirement is to keep it below 0.03
