Hydraulic rotary joint is a device that transports fluid media such as compressed air, cooling water, hydraulic oil, and heat transfer oil for two relatively rotating pipelines.

First: the role of hydraulic rotary joints

As a self-balancing element, the hydraulic rotary joint can transmit pressure oil or other fluids to the hydraulic rotary cylinder, so that the piston of the equipment moves left and right, so as to realize the radial loosening of the power chuck. During the return stroke, the hydraulic rotary joint will benefit from the pressure oil, and will be reset by the action of the spring to realize the chuck clamping. The rotary sealing part of the hydraulic rotary joint is installed on the mandrel of the equipment, and its main function is to form two independent sealing spaces to isolate the oil inlet chamber.

Second: the selection of hydraulic rotary joints

1. The type of rotary joint to be used is determined according to the structure of the device. The input medium and the output medium are inherent characteristics of the device. If the input and output media are on the same side, a dual-channel rotary joint must be selected. If the input and output media are on both sides, it must be Choose a rotary joint with a single-pass path; when the equipment transports multiple media or requires transporting media to multiple locations, you should consider selecting a multi-channel hydraulic rotary joint;

2. According to the required flow of input and output media, select the diameter of the rotary joint and the connection port of the standard line;

3. According to the pressure of the medium and the speed of the equipment, select the hydraulic rotary joint with appropriate performance;

4. According to the connection structure of the equipment and the rotary joint, determine the flange type or screw connection and the inner pipe rotary type or fixed type connection. At the same time, when choosing the threaded connection, please pay attention to the rotating joint of the connection. The rotation direction of the equipment needs to be clear.

Again: the wide application of hydraulic rotary joints

Hydraulic rotary joint is a connection and sealing device for inputting fluid medium from static piping to rotating equipment. The products are used in various construction machinery industries, wind power generation industry, automation industry, CNC machine tool industry, cable reel, printing industry, medical equipment, semiconductor industry, It is widely used in high-end fields such as rotary cutting tables, plastic molding, aerospace facilities, automated robots, and hydraulic fixture equipment.
