Definition - What does Angular Misalignment mean?
Angular misalignment happens in machines which include an operating shaft. This misalignment is of two types: horizontal and vertical. In angular horizontal misalignment, the motor shaft is under an angle with the pump shaft. However, both the shafts in this condition fall in the horizontal plan. In angular vertical misalignment, both the shafts are in the vertical plan along with the motor shaft under an angle. These misalignments of the shafts can result in the wear down of the equipment, leading to the production shut down of the refinery machines.
Petropedia explains Angular Misalignment
In the oil and gas industry, big turbines are used in refinery plants. These plants have turbine machines that have shafts fitted into them. Shaft alignment plays a crucial role in determining the functioning of the turbines. If the alignment is not achieved in a particular device, then it can lead to shaft misalignment which is of two types, i.e., angular and parallel misalignment. Angular misalignment is a state of shafts where the shafts can be in horizontal or vertical plan. If the motor shaft is under an angle with the shafts in vertical position, then it called an angular vertical misalignment. Similarly, if a motor shaft is under an angle with the shafts in horizontal position, it is called an angular horizontal misalignment.
