Surface deviation measurement, must in every 180 degrees corresponding to the two radii are equal to each other in order to eliminate errors caused by movement of the rotor. Only a support bearing of the rotor, WA couplings, such as the use of temporary leave the Center, should pay attention to keep the rotor in the measuring process in the center of the bearing oil retaining the nest does not change. Steam oil block, there should be sufficient clearance between the rotor and, in rotors make sure rotor is not on the block or seal oil. At the time of measurement, connections are not allowed between two rotors, each in a free State. Not allowed in case of assembled sleeve, Center work on the toothed coupling. Coupling tool should have adequate stiffness, installation must be secure and reliable. Coupling Center using a dial indicator, the table should be put in prison and avoid touching, to ensure correct measurement. Coupling disc after a week to return to the original position, circumference of dial gauge reading should be able to go back to the original value. When measuring the clearance of end, into the feeler of the gap should not exceed four at a time, when the gap is too large, you can use the gasket with the feeler gauge measurement of gauge blocks or finishing. bearing surface, markup should be in accordance with the mounting support pads, and retest the thickness. Once the lifting cylinder measurement of surface and internal cylinder surface height difference, compared with the original values confirm the location. Internal vertical and horizontal cylinder under state key insertion installation complex measuring cylinder in axial position. B
