Jinan cylinder in the advantage position in the industrial application

In the late ninety s, Japan and other major industrial developed country, even the electric actuator is about to replace the cylinder, cylinder of jinan will quit the stage of history. Because it is widely believed that the electric actuator motor in high energy conversion efficiency, low energy conversion efficiency, the cylinder inefficient products will be eliminated. A decade later, however, the electric actuator has not gained popularity in industry site, the size of the market also has the very big disparity compared with pneumatic. In the industrial developed countries, and, as well as the emerging industrial countries such as China, jinan cylinder sales not only failed to reduce, but also in steadily on the increase. In China, in recent years, annual growth of the sales of the cylinder has been maintained at more than %. If need scientific and objectively evaluate the both, must adopt the whole life cycle assessment ( LifeCycleAssessment) Technique, consider more manufacturing stage, stage of use, abandoned stage three stages of comprehensive index. Specific indicators are cost, energy consumption, environmental burden ( Mainly is the emissions, etc. ) 。 In the running energy consumption (such as cost, electric actuators Using phase) Has the advantages on cost, but the maintenance costs, Using phase) And the acquisition cost ( Manufacturing stage) Was much higher than the cylinder, on the index based on the sum total of all costs more. On the total cost, our research results show that the cylinder has certain advantages in most industrial applications. Comprehensive the above analysis, we should see, cylinder, with the characteristics of electric actuators have not simply with the efficiency of the high and low to evaluate their quality. With the development of electrical technology, will further decline in the cost of the electric actuator, expect its application fields will also further extension, but completely replace the imbibition non-clog sewage pump cylinder is unrealistic. From the front of the market form, has been mentioned that if electric cylinder from the start, with reference to the shape of cylinder and the installation size production, is a good place to start. For there is no ISO standards and pneumatic rodless cylinder sliding table, also adopt corresponding to the appearance and installation dimensions, the convenience of measures to prevent gas drive and electrical drive in installation, add or replace unnecessary competition. FESTO has electric product contains a variety of free combination of fetching module and multi-axis system. In the Festo, electric drive is not competitive products, pneumatic drive, but a perfect complement to pneumatic drive performance. The characteristics of the electric drive is accurate and flexible. Rapidly disappearing in the force and need accurate positioning applications, electric drive is no congestion self-priming sewage pump ideal solution. Therefore the development of jinan and electric actuator cylinder should be in a very good condition and complementary, according to the two door will be the natural scientific development laws of technology development.
