The characteristics of the pneumatic valve actuator and matters needing attention

Pneumatic actuators, pneumatic valve actuator is also called the executor of the pneumatic control system, has a compact structure, small volume, reliable operation, low coefficient of flow resistance, good sealing, easy maintenance, easy installation, strong adaptability, etc. Pneumatic valve is mainly divided into pneumatic sealing valve and pneumatic hard seal valve two kinds big. A, pneumatic valve actuator installation requirements of this device:, but the motor should be in level state, the electric box cover in a horizontal or vertical state for the recommended installation form, it is good for soothing, debugging, maintenance and manual operation. , when installation should guarantee the space required for the maintenance inspection personnel disassemble parts, installation, remove the debugging not damage when the seal face, sealers and explosion-proof electric explosion-proof surface, and should be coated with anti-rust oil on the surface of the explosion. Two, use pneumatic valve pneumatic head the note, not in the explosive environment down electric lid charged debug electric actuator, opened the electric box cover, must cut off power supply. Window, opening may not collide with hard objects. Open, not in the rainy day than outdoor electrical box cover, motor sealing parts, etc. , after inspection and maintenance, should be the electric box cover, motor and other sealing parts cover tightly fastened, in case of rain, moisture, corrosion caused by electrical component failure and parts. , after installation or reinstall, electric operation for the first time, must check valve is in middle position, direction, must be conducted in accordance with the requirements of debugging mode, item by item check parts after normal, can be put into use. , pneumatic valve gear in a three-phase motor, valve for continuous working hours must not exceed rated minutes, installation and debugging must pay attention to, in case the motor overheating. When the valve is rarely used, it shall make regular start check electric actuator system.
