The role and shape of various rotary joints no matter how changes, its structure will inevitably due to the following components: 1 shell, 2 center shaft, 3 bearings, 4 seals, of course, gaskets, hole cards, grease nipples, etc. Wait, we will not elaborate on it.
Next we look at what these components play in the rotary joint.
First of all, the housing, like the skin of our body, is a container that carries and wraps the components of the rotary joint. Its role is to fix the internal parts so that each part can reach normal operation.
Then, the central shaft, which bears the radial seal of the swivel joint, assumes the connection of the joint to the machine, and also the guide that carries the fluid. The "rotation" of the swivel is the 360-degree rotation of the center axis as the machine moves.
The bearing bears the radial load of the central shaft and prevents the swinging amplitude of the rotary joint (central shaft) from rotating excessively. If it is used at high speed, high-speed rotary bearings can be replaced.
Finally, seals, due to the use of the environment and the media will have different types of seals, such as flat seals, mechanical seals, high temperature spherical seals, etc., are used to prevent the fluid from entering the rotary joint after the rotation in the process of leakage The quality of the seal directly affects the life of the rotary joint. Why is the price of rotary joints in the market high or low, in addition to the brand benefits and production processes, a large part of the reason is that manufacturers choose the seal is good or bad. Our Hongchang Jufa focused on rotary joints for 20 years. We have chosen the seals with first-rate quality and performance. We are not seeking the best and only seeking better. This is the basis for our 20-year history!

Although there are many models of rotary joints, there are many types of water, oil, and steam. They all have different shapes and have their own strengths. However, the main components of the rotary joints are almost the same. Let's say what are the main components of the rotary joint and what their role is.
