What is turbine alignment?
Alignment means getting the centerline of the motor shaft in line with the centerline drive shaft. With misalignment, a technician is measuring exactly how far about the two It can seem that preventative maintenance cuts into operations, but reducing turbine repairs means across the board cost savings.
What is the purpose of shaft alignment?
While misalignment has no measurable effect on motor efficiency, correct shaft alignment ensures the smooth, efficient transmission of power from the motor to the driven equipment. Incorrect alignment occurs when the centerlines of the motor and the driven equipment shafts are not in line with each other.
Why is it important to perform a generator alignment?
Properly aligned shafts are able to spin freely and not induce other unwanted forces to the system. These unwanted forces will damage and/or destroy bearings, seals, and couplings, and eventually the gearbox or generator.
What is a 16 point alignment check?
A “16-point check” has been the standard measurement method for verifying this coupling alignment. In its core form, it is like the “rim and face” check used in standard dial indicator alignment. The rim readings are measured by a dial indicator that indicates along the edge of the coupling.
What is axial alignment?
3. Axial. An axial misalignment means the two ends of each axis, or shaft, don’t meet. They are parallel, but when fully extended, the ends do not come together. This kind of misalignment can also be called an end float because the ends of the shafts “float” but do not connect, meaning they can move in and out.
What is alignment explain it?
Definition of alignment 1 : the act of aligning or state of being aligned especially : the proper positioning or state of adjustment of parts (as of a mechanical or electronic device) in relation to each other. 2a : a forming in line.
What is alignment method?
Rim and Face alignment method are oldest method used for shaft alignment of misaligned equipment/shaft. In this method two dial indicator ( rim and face dial ) are used to determine the relative position of movable shaft with respect to stationary shaft.
What is axial and radial alignment?
Misalignment can occur in three ways: Radial (offset or parallel) misalignment. The centrelines of the two shafts are parallel but offset. Axial (or end float) misalignment. The two shafts are aligned but one (or both) axles are prone to in/out movement along the centreline.
What is alignment and types of alignment?
Alignment is how text flows in relation to the rest of the page (or column, table cell, text box, etc.). There are four main alignments: left, right, center, and justified. Left-aligned text is text that is aligned with a left edge. Right-aligned text is text that is aligned with a right edge.
What is called alignment?
1 : the act of aligning or state of being aligned especially : the proper positioning or state of adjustment of parts (as of a mechanical or electronic device) in relation to each other.
What is radial alignment?
Radial. In shaft alignment, radial refers to the measurement along the outside edge of a coupling. Reverse Dial Indicator Method. A method to measure shaft misalignment by using two dial indicators mounted on opposing shafts.
