Coupling refers to a device that connects two shafts or shafts with rotating parts, rotates together during the transmission of motion and power, and does not detach under normal circumstances. Sometimes it is also used as a safety device to prevent the connected components from bearing excessive loads, serving as overload protection。
Unit coupling alignment
1、The centrifugal compressor has a high rotational speed and strict requirements for the alignment of the coupling. The surface of the coupling should be smooth and free of defects such as burrs and cracks。
2、When using a dial gauge for measurement, the accuracy of the gauge must be qualified, and the gauge frame should have a sturdy structure, light weight, high rigidity, firm installation, and no shaking. When using, the deflection of the meter frame should be measured to correct the measurement results。
3、The adjustment gasket should be clean, flat, free of creases, burrs, etc. Verify that the distance between the shaft ends of the unit meets the requirements of the drawing. Align the alignment charts or cold alignment data provided by the manufacturing plant. Dry stainless steel diaphragm coupling, no lubrication, no maintenance, and equipped with safety protection cover。
