The function of rotating cylinder
The rotary cylinder is also a type of pneumatic actuator. It functions like an electric motor or a hydraulic rotary cylinder. That is, the torque is output and the drag mechanism performs rotational motion. Rotary cylinders, like other pneumatic components, have many unique characteristics and are used in many situationsRotating cylinder can reduce the cost and become more technically perfect. The drive of the continuous rotary mechanism should be driven by a rotating cylinder, which can not only adjust the speed steplessly, but also facilitate forward and reverse rotation, is suitable for harsh environments, and can be started up.
Rotary cylinders can be divided into volumetric and turbine types according to their working principles
Turbine-type rotating cylinders generally convert the flow energy of the air directly into the mechanical energy of the working wheel through the nozzle. Its advantages are large capacity ratio, high output shaft speed, and the number of nozzles can be changed to adjust the power;disadvantages are low efficiency at low power, complicated reversal, and reduced efficiency when working conditions change drastically. The operation is unstable at low speeds.
Rotary cylinder application
The rotating cylinder is driven by compressed air and can work normally in harsh conditions such as flammable, explosive, high temperature, vibration, moisture, dust, etc. It also has overload protection function and can be directly Start with load;can run continuously with full load for a long time. Mostly used in high speed and constant load conditions. The working principle of the positive displacement rotary cylinder is similar to that of the hydraulic rotary cylinder. According to the structure, it can be divided into vane type, piston type, gear type, etc. The most common ones are piston-type rotary cylinders and vane-type rotary cylinders. Vane-type rotary cylinders are simple to manufacture and compact in structure, but have small low-speed motion torque and poor low-speed performance. They are suitable for medium and low-power machinery and are currently used in mining and pneumatic tools. Commonly used in China. For high speed and low torque, it is advisable to use vane rotatingcylinder< /a>When the rotation speed of the mechanism is high and the torque is small, the blade type rotating cylinder can be directly driven;the maximum speed can reach 5×.
