Today, the degree of industrialization is more and more high, especially in the field of automatic production with higher explosion-proof requirements, the application of explosion-proof electric valves is becoming more and more extensive. The driving source of explosion-proof electric valve is the power supply, and its main parts are the explosion-proof electric actuator. The operation quality of the explosion-proof electric actuator directly affects the operation of the explosion-proof electric valve.

       The main role of explosion-proof electric actuator in the valve is to drive and control the opening and closing, and can realize remote automatic control, not only can be operated on a single machine, but also can be multi-machine connection control, it can be said that it is the current industrial automation production field control and program control in one of the more important execution units. However, it will inevitably shift and wear phenomenon after a period of use, so it needs to carry out regular maintenance, the specific maintenance content is described as follows:

       1, the mechanical part of the component wear can be repaired by grinding, spraying, grinding, matching, plating, modification and other processes.

       2, before the repair of the mechanical part should be cleaned and checked, the electrical part should be checked accordingly, such as whether the circuit is neatly arranged, whether the wiring point is firm, etc.

       3, check whether there is a shift between the parts of the mechanical part, such as bearing parts, tooth surface, slider and other running parts clearance is normal and worm gear, gear, screw, nut and other transmission components meshing surface is normal, such as abnormal should be in accordance with the instructions to use the corresponding process method for processing.
