Working Principles of Various Types of Rotary Joints

Rotary joints are classified according to different needs, uses, working principles, etc., and there are corresponding differences in their classification and working principles.

The connection method of the circuit rotary joint can be selected according to the working situation.  The entrance of the transmission medium can freely choose to enter from the side or back according to the working conditions.  The sealing surface and sealing ring are made of special materials, which are wear-resistant, long-lasting, corrosion-resistant, and leak proof.  There are two precision bearings inside the rotary joint, which operate smoothly and persistently, are sturdy and flexible, have a low coefficient of friction, and can therefore operate at high speeds.  The wear of internal seals can be visually observed from the appearance of the product, which can prevent mechanical shutdown or damage, achieve preventive effects, and reduce losses.  The replacement and repair of worn seals are simple, and there is no need to purchase new products, saving costs.  Single circuit series rotary joints: meet the needs of various industries at home and abroad, including fluid media such as water, steam, oil, air, vacuum cutting fluid, toluene and other chemical solvents.

The connection method of a single circuit rotary joint can be selected according to the working situation.  The entrance of the transmission medium can freely choose to enter from the side or back according to the working conditions.  The sealing surface and sealing ring are made of special materials, which are wear-resistant, long-lasting, corrosion-resistant, and leak proof.  There are two precision bearings inside the rotary joint, which operate smoothly and persistently, are sturdy and flexible, and have a low coefficient of friction, allowing for high-speed operation.  The wear of internal seals can be visually observed from the appearance of the product, which can prevent mechanical shutdown or damage, achieve preventive effects, and reduce losses.  The replacement and repair of worn seals are simple, and there is no need to purchase new products, saving costs.  

Double circuit rotary joints can be divided into fixed double circuit and rotary double circuit rotary joints.  The sealing surface and sealing ring are made of special materials, which are wear-resistant, long-lasting, corrosion-resistant, and leak proof.  The wear of internal seals can be visually observed from the appearance of the product, which can prevent mechanical shutdown or damage, achieve preventive effects, and reduce losses.  There are independent pipelines inside, which can be selected according to different working conditions to maximize efficiency.  The shell and shaft are supported by precision bearings, making them flexible and lightweight during rotation, with low friction. Liquid media can include water, oil, air, etc., and are widely used in various industries.  The replacement and repair of worn seals are simple, and there is no need to purchase new products, saving costs.  

Product features:

Rotary joint RF type features:
High quality rotary joint and precision bearing device are installed on a high rigidity shaft, with no vibration during long-term operation. The shaft is subjected to special heat treatment to increase rigidity. The fixed ring closure is made of special materials, such as wear-resistant carbon graphite, which is waterproof and dry running. Especially, the size of the rotary closure surface must be reduced to the minimum, and even under high pressure, our  company's long-term mechanical experience has made it possible to achieve good balance on the sealing surface. The RF type joint uses bronze fixed rings for use in high-pressure 200 bar environments.
Application scope:
general tools, workstations, computer electronic value control, rotary distributors.

In RLB/RLF rotary joints, it is very difficult to connect the coolant for rotation, especially under high-speed conditions. A special labyrinth component in the parts is used to prevent leakage. The two sealing surfaces are refined by carbonization to ensure long-term operation and wear resistance. The sealing ring maintains appropriate balance and even ensures extremely low wear at high speeds.  

The RMB/RMF rotary joint has the characteristic of opening/closing function. The opening/closing function prevents high-precision splashing during the instantaneous engagement period when the coolant passes through. When the coolant stops passing through, the closed surface immediately opens to avoid friction, and this function ensures a long service life.  The important thing is to use a maze like component to prevent a small amount of liquid from leaking back. The two contact surfaces are made of wear-resistant and mechanically shock resistant tungsten carbide, using stainless steel springs that do not rust, hinder, rotate, or undergo any changes. The coolant connection direction between RMB and RMF is different.

The RHB/RHF type rotary joint has grooves on the surface of the main body, which can help dissipate heat during high-speed rotation.  It has an open/close function.

When the coolant passes through the open/close mechanism, the contact surface automatically closes to prevent splashing. When the coolant terminates, the contact surface immediately opens to avoid dry friction, ensuring that the contact surface is not damaged during long-term operation. More importantly, there are labyrinth components to prevent splashing.  The two contact surfaces are made of wear-resistant and mechanically shock resistant tungsten carbide, using stainless steel springs that do not rust, obstruct, rotate, or undergo any changes. The coolant connection direction between RHB and RHF is different.  

The RGC series rotary joint products are designed as simple cutting tools for general deep hole machining. This type of rotary joint has high speed, strong pressure, and only requires one set of equipment to cooperate with the factory's existing equipment. This series of products saves costs and allows users to maximize economic benefits.  Widely applicable, widely used in CNC lathes, general boring, milling, drilling machines and machining center machines, drilling deep holes, without the need for dedicated deep hole machining machines.  The scope of use includes mold, hydraulic industry, printing, packaging, and general hardware drilling processing, drilling industry, etc.
