The application of hydraulic rotary joints is relatively wide. The materials are generally divided into stainless steel or alloy shells. They mainly transport liquid media such as hydraulic oil and water. Among them, the multi-channel structure is more common.
There are two close bearings inside the rotary joint, which are stable, durable, reliable, firm and flexible, with low friction coefficient, so it can run at high speed. Generally speaking, hydraulic rotary joints are usually used to deliver hydraulic medium to hydraulic actuators on rotating equipment. This kind of joint has high requirements for material quality, processing quality and installation accuracy. If used improperly, it is prone to failure and affect the normal operation of the connected equipment.
Hydraulic rotary joints are generally prone to failures, so please take precautions!

1. Leakage at the joint connection.
2. The movement speed is unstable.
3. The valve core is stuck or the movement is inconvenient, causing the actuator to malfunction.
4. The damping orifice is blocked, causing the system pressure to be unstable or the pressure cannot be adjusted up.
5. Valve components are missing springs or seals, or pipes are connected incorrectly, resulting in chaotic movement.
6. Improper design and selection will cause the system to heat up, or the action will not be coordinated, and the position accuracy will not meet the requirements.
7. The processing quality of hydraulic parts is poor, or the installation quality is poor, which leads to inflexible valve movements.
8. Long-term work, aging of seals, and wear of vulnerable components, etc., lead to an increase in internal and external leakage in the system, and the system efficiency is obviously reduced.
