Design structure and principle of high-speed rotary joint

High speed rotary joints are widely used in the machine tool industry, paper industry, steel industry, hydropower industry, plastic industry, rubber industry, engineering industry, etc. Their characteristics include high-precision bearing support, vibration free, wear-resistant, heat-resistant, and impact resistant tungsten carbide cover, hardened stainless steel spindle, and stainless steel spring installed outside the fluid to prevent fluid from impacting the spring. The excellent balanced seal ensures minimal friction.

The single channel rotary joint in the rotary joint mainly adopts mechanical structure sealing, which is a precision rotary joint. The stator is made of aluminum alloy material, and the main shaft is made of hard stainless steel. The front end is supported by two high-precision roller bearings, and the rear end is equipped with corrosion-resistant springs. The front and rear sections use hard metal as a flat seal. The medium enters from the stator hole and exits from the rotor center hole, which can transmit a single medium. The threaded end of the rotor is connected to the equipment rotating shaft, and the speed is determined by the rotation speed of the equipment main shaft. It is a passive rotating component that mainly compensates for the spring according to the thrust of the medium. It has high wear resistance and automatic compensation function. The advantage of using a connection and disconnection balance seal is to stabilize internal pressure and effectively prevent leakage of rotary joint products. The, The ordinary single channel rotary joint adopts a sealing ring inside, but its disadvantage is poor wear resistance and the speed cannot be too high. The advantage is high compressive strength, suitable for use under high pressure. The single channel high-speed rotary joint can only rotate in one direction and cannot rotate forward or backward. The maximum speed of the high-speed rotary joint can reach 24000RPM and the pressure resistance is 50Bar. It is commonly used in deep hole drilling equipment and is a standard rotary joint product
