ABA Clamps hose fitting functions

The function of a rotary joint is to serve as a sealing connection device that inputs liquid from one side of a pipeline into rotating or reciprocating equipment and then discharges it from the equipment. In the case of bent pipes, especially metal hoses, a considerable total length is required for the stroke due to the large bending radius. By installing a rotary joint at the base, it can be completed with the shortest hose length, which not only saves space but can also be used to absorb hose torsion depending on the method of use. Hydraulic and water piping systems using assembled rotary joints can also accommodate complex movements. They can be used with confidence in locations where hoses are difficult to install or where significant leakage is a concern, and under severe environmental conditions such as high temperature and high pressure. For example, when a boiler burner is ignited, rotary joints installed for oil and steam piping can be used without problem even under severe conditions of high temperature, high pressure, and complex motion. In summary, rotary joints can be equipped on cylindrical, drum-shaped, frustum-shaped, and spherical rotating equipment, as well as equipment that reciprocates or oscillates at any angle, using gases and liquids such as steam, water, oil, gas, air, salt water, and ammonia for heating, drying, and cooling. They are also suitable for pneumatic and hydraulic related equipment used for clamping, braking, and gripping.

ABA Clamps hose fitting selection

Unidirectional flow type: Rotary joints are installed at both ends of the drum; fluid enters from one end and exits from the other, without using an inner pipe. Unidirectional flow type: A rotary joint is installed at one end of the drum, where fluid is both introduced and discharged; the inner pipe remains stationary relative to the rotation of the drum. Bidirectional flow type (inner pipe fixed): The difference from the previous type is that the drum contains different types of siphon tubes to discharge condensate; this type is mostly used for steam applications. Bidirectional flow type (inner pipe rotating): This type is used in structures where the inner pipe is fixed relative to the drum and rotates synchronously with it; in this case, fluid is introduced through the inner pipe and discharged through the outer pipe. Bidirectional flow type (inner pipe rotating): A siphon device that rotates synchronously with the drum is installed inside the drum to discharge condensate; this type is mostly used for steam applications.

ABA Clamps hose fitting installation

During handling and storage of rotary joints, impacts and drops should be avoided to prevent damage to interfaces and internal components. Install with concentric alignment as much as possible to ensure proper operation of the rotary joint. When installing thread-connected rotary joints, pay attention to whether the thread direction of the inner and outer pipes corresponds to the rotation direction of the drum, and ensure that the thread directions of the inner and outer pipes are consistent. The connection between the rotary joint and the pipeline must be made using flexible hoses; rigid connections are strictly prohibited. Connect the inlet and outlet of the rotary joint directly to the flexible hose as much as possible to reduce the auxiliary weight on the joint and extend service life. For the assembly of the inner pipe, pay attention to dimensional fit and auxiliary support for weight. For internally rotating rotary joints, a tolerance fit of H8/e7 is recommended for the cooperation between the inner pipe and the joint. The support and anti-rotation mechanism for the rotary joint should be appropriate; generally, the rod diameter should be 2mm smaller than the anti-rotation hole to avoid affecting the free adjustment and compensation of the rotary joint. Various connection methods for connecting rotary joints to equipment are available (customers can set up different types of connection methods according to the specific structure of the equipment used).
