Diaphragm coupling installation problem

Diaphragm coupling in the installation process will appear a variety of problems, when we encountered in the installation of how to judge? Here are diaphragm coupling problem: when installing the diaphragm coupling axis break, coupling bump into: to prevent such accidents, in addition to the axis of calibration, the location of the coupling hole and shaft and collision block position to be correct, also note that the impact point position to choose the right, under the first and second next to light, to stay in a distance (about 1/3), before hard slam. Other accidents may include: bump block pulley backing due to unsecured position, hoist chain sliding down, fuel shortage, fire alarm, etc. All should be noted in advance and carefully checked during tool preparation and operation training. When precision components such as bearings and mechanical seals are installed in advance on the spindle, it is forbidden to strike and impact the coupling forcibly to prevent damage or damage to precision components.
