    Cylinders can be divided into many categories. Spiral swing cylinders and cooling water rotation cylinders are two of them. Among them, spiral swing cylinders are a special type of cylinders that use high-angle spirals to achieve output swing.
    Spiral piston helical swing oil cylinder is one of them. Its structure consists of spiral rod, cylinder body, piston and spline, etc. The cylinder body is fixed, and a spline is processed at one end of the piston. The inner surface of the rotating sleeve is also splined and engaged with the piston spline. When the piston moves linearly along the spiral rod under the action of hydraulic pressure, it also rotates at the same time. This rotary motion is output by the rotary sleeve and the flange.
    Since the structure of the spline piston helical swing oil cylinder is relatively simple, it is easy to process and can transmit large torque. However, since the axial length of the rotating sleeve is greater than or equal to the length of the spline on the piston, and when the swing angle of the cylinder is greater than 360 °, this length is also greater than a lead. Therefore, this structure has a large axial dimension.
    In contrast, the cooling water rotating oil cylinder has the characteristics of small volume, small space and low friction torque. The seal is a balanced seal made on CNC machine tools and special grinding machines, so it shows good sealing performance. And its appearance is very smooth and very reliable.
    When using cooling water to rotate the oil cylinder, you must have some understanding of its basic parameters. Its pressure is ≤1.0MPa; temperature is ≤100 ℃; speed is ≤1000RPM; the main media used are water, air, brine, hydraulic oil Etc., provided an important role for the cooling of the oil cylinder.
    Because the actual application environment is different, the cooling water rotating oil cylinder will be composed of silicon carbide, impregnated graphite, tungsten carbide, bronze and other friction groups, so it can well block broken pins and scaling. , Rust and other debris to the sealing surface damage, thereby ensuring the integrity of the entire cylinder and normal operation.
    The above is the introduction of the respective characteristics of the spiral swing oil cylinder and the cooling water rotation oil cylinder, I hope to help everyone.
