Specializing in the production and sales of electric cylinders,Electric cylinder is a new revolutionary product. It is an executing element that can perform actions like a cylinder.Compared to cylinders, it is easier to operate,It can achieve actions such as opening doors, lifting, pushing and pulling, with thrust ranging from several kilograms to several tons.Fully electrified, only requires220V power supply, no need for gas source, no need for hydraulic station, one-time debugging, lifetime maintenance free.

The working principle of an electric cylinder isDrive the screw or synchronous wheel to rotate through the motor, and then convert it into linear motion through nuts or belts, and push the load to move. Electric cylinder combines the best advantages of servo motor-Precise speed control, precise speed control, and precise torque control are transformed into precise speed control, precise position control, and precise thrust control; A new revolutionary product that realizes high-precision linear motion series.

1. Hardware composition of electric cylinder and traditional cylinder

In terms of hardware, traditional cylinders have many components and complex systems, so their hardware design time and cost are relatively high. From the perspective of usage conditions, the main components that cooperate with the cylinder in the pneumatic system are solenoid valves and air dryers, and its power output source is a screw air pump, which has a relatively low cost shared among each shaft.

The structure of the electric cylinder system is very simple, with only electric cylinders, drivers, and controllers as the component types, so its hardware system integration is relatively simple. Each axis of the electric cylinder system requires a servo driver as the power unit output. At this point, the hardware cost of servo cylinders and drive systems is clearly high.

2. Comparison of energy consumption between electric cylinders and traditional cylinders

Due to the fact that the power of the cylinder needs to pass through air pressure as an intermediate medium, and there is a problem of gas source leakage during operation, the efficiency of its energy consumption exchange is not highThe power of an electric cylinder is directly converted into mechanical energy through electrical energy, resulting in higher efficiency in terms of energy consumption.justLow noise, energy-saving, clean, high rigidity, impact resistance, long service life, easy operation and maintenance.

3. Accuracy of electric cylinders and traditional cylinders

Traditional cylinders achieve speed control by adjusting the one-way throttle valves installed on both sides of the cylinder. This speed control method is only suitable for situations where the speed value is not required to be high. And the speed is affected by the pressure of the air compressor, as well as the size of the solenoid valve and vent hole diameter. The electric cylinder controls its operating speed by controlling the frequency of the output current, and has the advantage of continuous adjustability, fast response speed, and precise control of speed through a feedback system.

Flushing device(Rubber pad) to reduce or eliminate end impact. Or set up a small enclosed space at the end of the cylinder to convert kinetic energy into pressure energy. The electric cylinder detects its position in real-time through a microprocessor and precisely controls its speed. When moving to the end position, quickly reduce its running speed to achieve endpoint buffering control.

Due to the compressibility of gas and the instability of gas source pressure, the precision of controlling the force of the cylinder is not high.The maximum output force of ETH electric cylinder is 11.4T, and the Campax3 driver has a built-in force closed-loop module. With a fast scanning cycle of 125us, it can achieve an output accuracy of 0.2% for Lux.

　　4Comparison of Space between Servo Electric Cylinder and Traditional Cylinder

Compared to the large external dimensions of cylinders and gas-liquid supercharging cylinders, electric cylinders are compact in size. useFor example, for a product that outputs 5T ETH, the external framework of ETH100 is only 120mm, and the external appearance of ETH is smooth with light holes. There is only one slot on the cylinder block for installing sensors, which can be easily covered without any areas of dirt accumulation, making it cleaner and more environmentally friendly.

5. Diversified installation conditions to meet different needs

Can operate without failure in harsh environments, with a protection level of up toIP66.Flexibility in configuration, providing very flexible installation configurations; Install in a straight line or parallel with the servo motor;According to equipment requirementsAdd various accessories such as limit switches, planetary reducers, pre tightening nuts, etc.

Electric cylinders are widely used in lithium battery equipment, construction machinery, rubber equipment, electronic assembly equipment, production line automation, simulated driving, rewinding machines, automotive grinding tool pressing equipment, etc.
