Pneumatic and electric systems are not mutually exclusive. Instead, this is just a question that asks for a different question. The advantages of pneumatic drives are obvious. When faced with harsh environmental conditions such as dust, grease, water or detergents, pneumatic actuators are more adaptable to harsh environments and are extremely rugged. Pneumatic drives are easy to install and offer a typical gripping function that is inexpensive and easy to operate.
An electric drive with a servo motor has advantages in situations where the force is rapidly increasing and precise positioning is required. For applications requiring precise, synchronous operation, adjustable and regulated positioning programming, electric drives are the best choice. The electric drive system consisting of servo or stepper motors with closed-loop positioning controllers can complement the shortcomings of pneumatic systems. At the office.
From the perspective of technology and cost of use, cylinders have obvious advantages, but which technology should be used for driving control in actual use, or should be considered from multiple factors. In modern control, various systems are more and more complex and more and more sophisticated. It is not a kind of drive control technology that can satisfy various control functions of the system. The cylinder can be easily realized in a fast linear circulation motion. The structure is simple, the maintenance is convenient, and it can be used in various harsh working environments, such as explosion-proof requirements, dusty or wet working conditions.
Electric actuators are mainly used in applications requiring precise control. Nowadays, the requirements for flexibility in automation equipment are constantly improving. The same equipment is often required to adapt to the processing needs of different sizes of workpieces. The actuator needs to be controlled by multiple points and the actuator is required. The precise control or simultaneous tracking of the running speed and torque is not possible with conventional pneumatic control, and electric actuators can easily implement such control. It can be seen that the cylinder is more suitable for simple motion control, while the electric actuator is mostly used for precision motion control.
