The advantages of cylinder compared with electric actuators

Cylinder is mainly used in printing, semiconductor, automation control, robot applications. So compared with electric actuator cylinder, what are the advantages? Low, cylinder on the user's requirements. The principle of cylinder and simple structure, easy to install and maintain, is not high to the requirement of users. Electric cylinder, on the other hand, engineers must have a certain electrical knowledge, or is likely to make it damaged because of the wrong operation. Big, cylinder and output force. Cylinder is directly proportional to the square of the output force and the cylinder diameter; And the output of the electric cylinder force associated with three factors, cylinder diameter and power of the motor, screw pitch, diameter and the greater the power, the smaller the pitch, the greater the output force. For the same diameter of electric cylinder, although different products vary, but generally not more than N. It is obvious that the cylinder in the output power is even more advantages. Strong adaptability, cylinder. Cylinder can work normally in the high and low temperature environment and have dustproof and waterproof ability, can adapt to all kinds of harsh environment. And electric cylinder due to have a large number of electrical components, the demand is higher, to the environment and poor adaptability. Compared with electric actuators, cylinder can work reliably in harsh conditions, and the operation is simple, basic maintenance can be realized. Cylinder at making reciprocating linear motion, especially the most suitable for industrial automation transmission requirements -- — Artifacts of straight line handling. And, just adjust on either side of the one-way throttle valve installed in the cylinder can simply achieve steady speed control, has become the greatest feature of the cylinder driving system and advantage. So for no multipoint positioning requirement of users, the vast majority of from the point of use convenience more inclined to use the cylinder. The current industrial field use the application of the electric actuator is mostly high-precision positioning, more difficult to achieve this is due to using cylinder, the next best results. Electric actuators are mainly used for rotary and oscillating condition. Its advantage is fast response time, by feedback system to control the speed, position and torque accurately. But when you need to complete linear motion, need through the cog belt or screw mechanical devices such as transmission, so the structure is relatively complex, and professional knowledge of working environment and the operation and maintenance personnel have higher requirements.
