1. Before installing the rotary joint, remove all hard particles and other contaminants from the pipeline, as well as from the interior of the roller and rotary joint. During installation, to prevent damage to the bearings from tightening torque, first use a transition joint or flange to connect the rotary joint to the metal hose. When installing, use a vise to clamp the end of the rotary joint, but do not clamp the housing to avoid deformation.
2. Installation of the inner tube: Connect the inner tube to the rotary joint. After installation, the inner tube should be horizontal inside the equipment roller, aligned with the roller's centerline without any deviation. This can prevent excessive wear and tear, as well as vibration during rotation of the inner tube. After installation, the rotary inner tube should protrude 3-5mm from the housing.
3. Installation of the hollow shaft: Connect the hollow shaft to the equipment shaft neck. During the connection, ensure that the hollow shaft and the shaft neck are as concentric as possible. If the rotary joint is connected to the equipment shaft neck flange using a half-split ring quick-change flange, please saw the tapered half-split ring in advance along the center with a saw cut width of 2-3 millimeters and remove any burrs.
4. Installation of metal hoses: Metal hoses must be used for connecting rotary joints and fixed pipelines. The metal hoses should be of sufficient length. After installation, the metal hoses should be in a relaxed state without exerting external force on the rotary joints.
Note: The installed metal hose should not be eccentric, nor should it be in a compressed or tensioned state. Otherwise, it may cause the rotary joint to deviate from the centerline of the roller shaft neck, affecting the sealing effect, leading to seal failure and leakage, and reducing the service life of the rotary joint's ball bearing.
