Main characteristics of 20 19-07-23 electric cylinder
1. Energy-saving and clean, long service life, simple operation and maintenance, and strong environmental adaptability. Servo electric cylinder is not easy to be affected by environmental temperature, and can work normally and trouble-free in harsh environments such as low temperature, high temperature, rain and snow. The protection level can reach IP66. The seal prevents the pollution of dirt and water outside the cylinder and the leakage of internal lubricant, and realizes high strength, high speed, high precision positioning, stable movement and low noise after long-term work.
2. High transmission efficiency. The electric cylinder with precision transmission elements such as precision ball screw or planetary roller screw saves many complicated mechanical structures and greatly improves the transmission efficiency. The transmission efficiency of this kind of electric cylinder can reach above 90%.
3. High positioning accuracy. The ball screw servo electric cylinder can achieve accurate positioning of about 0.0 1mm through servo control, with high positioning accuracy, which is suitable for applications with high precision requirements.
This occasion. Electric cylinder can achieve high positioning accuracy in semi-closed loop, while hydraulic cylinder and cylinder must adopt full closed loop control system to achieve the same positioning accuracy.
4. Simple structure, small occupied space and convenient maintenance. The electric cylinder is mainly composed of a motor and a nut and lead screw mechanism, which is simple, small in size and does not occupy too much working space. Because of the simple structure, it is easy to find the cause of the fault when it occurs, and the usual maintenance is also very convenient.
5. High reliability and safety. The electric cylinder can be equipped with advanced sensor system and various stroke control devices to detect and feedback the working state of the electric cylinder and prevent accidents.
6. Stable operation and long service life. When ball screw or planetary roller screw is used in electric cylinder, the friction of transmission part will be greatly reduced, which is beneficial to reduce material wear, improve operation stability and prolong service life.
7. Fast response, adjustable linear working speed in a wide speed range, and stable low-speed operation. Generally, the working speed of hydraulic cylinder can only reach 35mm/s, while that of ordinary electric cylinder can reach 55mm/s.. The speed of electric cylinder with planetary roller screw can even reach 2000 mm/s, and the speed advantage is very obvious. In addition, the hydraulic cylinder is prone to creep under low speed and heavy load, while the electric cylinder does not have this shortcoming.
8. Accurate control and good synchronization. When multi-drive synchronization is needed, it is difficult to achieve high-precision synchronization by using hydraulic cylinders or cylinders because the frequency characteristics of control loops of multiple independent hydraulic cylinders or cylinders are consistent.
Is a very difficult thing. It is easy to achieve synchronization by using multiple electric cylinders, because the frequency characteristics of the electrical system are relatively easy to achieve consistency.
9. Electric cylinders can also replace some hydraulic cylinders and pneumatic cylinders. The components that can realize linear transmission mainly include electric cylinder, hydraulic cylinder and air cylinder. The following table shows the main differences between them. By comparison, it can be seen that electric cylinder is simpler than hydraulic cylinder and cylinder, and is less affected by temperature fluctuation.
