high speed rotary joint is a kind of equipment that conveys compressed air, cooling water, hydraulic oil, heat transfer oil and other fluid media for two relatively rotating pipes.

First of all: the role of high speed rotary joint

As a self-balancing element, high speed rotary joint can transfer pressure oil or other fluids to the hydraulic rotary cylinder to move the piston of the device from side to side, thus achieving radial loosening of the power chuck. When returning, the hydraulic rotary joint benefits from the pressure oil will go to pressure and reset by the action of the spring to achieve chuck clamping. high speed rotary joint's rotary seal part is installed on the mandrel of the equipment, and its role is mainly to form two independent sealing spaces to isolate the oil feed chamber.


Second: the selection of high speed rotary joint

1, according to the structure of the equipment to decide the type of rotary joint to use, the input medium and output medium is the inherent characteristics of the equipment, if the input and output media on the same side, you must choose a double-path type of rotary joint, if the input and output media on both sides, you must choose a single-path rotary joint; equipment conveying a variety of media or require the media to be transported to more than one location, you should consider choosing a multi-path type of hydraulic rotary joint ；

2, according to the required flow rate of the input and output media, choose the caliber of the rotary joint and the connection port of the standard line.

3, select hydraulic rotary joints with appropriate performance according to the pressure of the medium and the speed of the equipment.

4, according to the connection structure form of equipment and rotary joint to decide flange type or screw connection and inner tube rotary or fixed connection, at the same time, when choosing threaded connection, please note that the connected rotary joint needs to clarify the rotation direction of the equipment.

Again: the wide application of high speed rotary joint

high speed rotary joint is a connection sealing device for feeding fluid medium from static piping to rotating equipment, which is used in various construction machinery industry, wind power industry, automation industry, CNC machine tool industry, cable reel, printing industry, medical equipment, semiconductor industry, rotary cutting table, plastic molding, aerospace facilities, automated robots, hydraulic clamping equipment and other high-end fields are widely used.
