Since the electric actuator drive unit has more parameterized settings and high integration, in the event of a fault, the entire component must be replaced, and when the driving force required by the system increases, the components must be replaced in a complete set, so The comparison shows that the cylinder has a large advantage in terms of purchase and maintenance costs.
Cylinders still have obvious advantages. For the pneumatic system, the control system and the actuator are very simple. Each cylinder only needs to be equipped with a solenoid valve to complete the switching of the gas path, and the motion control is performed. The probability of the cylinder failure is relatively small, the maintenance is simple and convenient, and the cost is low. Also low. For the electric actuator, although the electric energy is relatively simple to obtain and the energy cost is low, the purchase and application cost are high, and not only the motor needs to be configured, but also a mechanical transmission mechanism and corresponding driving components are needed. At the same time, the use of electric actuators requires a lot of protection measures. Wrong circuit connections, voltage fluctuations and overload of the load can cause damage to the electric drive. Therefore, it is necessary to install a protection system on the circuit and the machine, which adds a lot of extra expenses.
Comparison of market prospects
Cylinders and electric actuators have their own characteristics. It is not possible to evaluate their advantages and disadvantages simply by using the level of efficiency. With the development of electrical technology, the cost of electric actuators will further decline. It is expected that the application field will be further expanded, but it is unrealistic to completely replace the cylinders with self-priming non-blocking sewage pumps. From the market form, it has been mentioned that if the electric cylinder is produced from the beginning with reference to the shape of the cylinder and the installation and connection dimensions, it is a good start. For the rodless cylinders and pneumatic slides that do not have the ISO standard, the corresponding shape and installation connection size are also adopted. This convenient measure can prevent unnecessary competition between the air drive and the electric drive in installation, addition or replacement.
Electric drives are not a competing product for pneumatic drives, but rather a complement to the performance of pneumatic drives. The characteristics of the electric drive are ^ and flexible. In applications where the force quickly disappears and requires positioning, the electric drive is an ideal solution for a non-blocking self-priming sewage pump. Therefore, the development of cylinders and electric actuators in the future should be in a very benign condition and complementary, and will certainly follow the development of the science and natural development of these two technologies.
