The plum blossom coupling is widely used, so our common coupling, also called claw coupling, is a combination of two metal claw discs and an elastic body.The plum coupling has a good balance performance and is suitable for high-speed applications (speed up to 30000 rpm), but it cannot handle large deviations, especially axial deviations.Today, the editor will tell you about the hot installation precautions of plum coupling.

　　1. Before heating, check whether the plum blossom coupling is paired with another coupling, especially if several units of the same unit are installed, find out the pair number or mark.

　　2. There should be no defects such as burrs and scratches on the mating surface of the plum coupling.

　　3. Always record the temperature rise and current value, and the temperature rise should not exceed 30°C per hour.

　　4. After the temperature rises to 100°C, the inspectors must pay attention to safety.

　　5. When using the sample rod to measure the aperture value, it must be powered off.

　　6. Fire fighting equipment should be provided in the heating area.

　　7. After the plum blossom coupling is hot-mounted on the shaft, use cold water to pour the journal to cool it to prevent the heat from spreading to the armature and affecting the insulation.
