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 pump alignment important?
Proper alignment of the pump shaft with the driver can reduce vibration and significantly improve reliability. For appropriate applications, the time, expertise and instruments needed to achieve precision alignment (tolerances of less than 0.005 in) will prevent seal leakage and extend bearing life.
What is the purpose of alignment of pump and motor?
Motor-Pump alignment is critical for these reasons: It minimizes the forces of misalignment acting upon the bearings and seals of both components. It minimizes wear of the coupling. It can help reduce energy costs.
What is alignment of pump and motor?
Alignment is essentially based on measuring accurately the position of motor and pump shafts at two points or more. Various devices are available for measuring alignment offsets: feeler gauges, callipers, dial indicators and laser alignment tools.
What is the meaning of motor alignment?
Shaft alignment is the process of aligning two or more shafts with each other to within a tolerated margin. It is an absolute requirement for machinery before the machinery is put in service.
What is the main goal of shaft alignment?
The objective of optimized shaft alignment is to increase the operating life span of rotating machinery. To achieve this goal, components that are the most likely to fail must be made to operate within their acceptable design limits.
What is the purpose of shaft alignment?
Simply stated, the objective of shaft alignment is to increase the operating lifespan of rotating machinery. To achieve this goal, machinery components that are most likely to fail must operate within their design limits.
How do you check motor and pump alignment?
Dial gauges or laser measurement devices are often used to provide more accurate measurements of the degree of misalignment between the motor and pump shafts.
How many types of pump alignment are there?
When speaking of a pumping system, proper alignment of two different types is important: the alignment of the pump shaft and the drive shaft, and the alignment of the pump flanges with the connecting piping.
What are the types of misalignment?
Recognizing 5 Common Types of Misalignment
- Parallel Misalignment.
- Vertical Angle Misalignment.
- Horizontal Angle Misalignment.
- Vertical Angular and Offset Misalignment.
- Horizontal Angular and Offset Misalignment.
Why the alignment of motor and load is more important?
Proper motor shaft alignment increases the operating life span of rotating machinery. 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. …
What is the meaning of misalignment?
: the condition of being out of correct position or improperly adjusted : bad or incorrect alignment Over time, because of damage and wear, typewriters develop faults and misalignments that render their typescript unique.—
What do you mean by 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. b : the line thus formed.
