To ensure optimal performance and minimize wear and tear, various techniques can be employed for pump shaft alignment during maintenance.
1. Straightedge and feeler gauge technique: This approach involves using a straightedge and feeler gauge to measure alignment between the pump and motor shafts. Placing the straightedge across the coupling faces, the gap between the straightedge and coupling faces is measured using the feeler gauge. The readings obtained determine the necessary adjustments for achieving proper alignment.
2. Reverse indicator technique: This method employs a dial indicator to measure misalignment between the shafts. Mounting the dial indicator on one shaft, it is positioned to sweep across the coupling faces of the other shaft. As the shafts rotate, any misalignment causes the dial indicator to move, visually displaying the misalignment. Adjustments are made until the misalignment is minimized.
3. Laser alignment technique: A more advanced and accurate method, laser alignment utilizes laser technology to measure shaft misalignment. Specialized tools project laser beams onto targets attached to the shafts, and the misalignment is displayed on a computer or handheld device. This allows for precise adjustments to be made.
4. Rim and face method: This technique involves measuring misalignment by using a dial indicator to measure runout at the coupling faces. A bracket spanning the coupling faces holds the dial indicator, which moves as the shafts rotate due to any runout. Adjustments are made until the runout is minimized.
5. Optical alignment technique: Optical alignment employs optical technology for measuring shaft misalignment. An optical alignment device consisting of a telescope and measuring targets is used. The telescope is aligned with the motor shaft, and targets are attached to the pump shaft. Misalignment is measured by observing the deviation between the targets and the crosshairs in the telescope. Adjustments are made until the misalignment is minimized.
In summary, these maintenance methods for pump shaft alignment play a crucial role in ensuring efficient and effective pump operation. They contribute to prolonged equipment life and reduced downtime.
During maintenance, there are several common methods of pump shaft alignment that can be employed to ensure optimal performance and minimize wear and tear.
