Characteristics and advantages of pneumatic actuators

The characteristics of the pneumatic actuator compact double piston gear, rack structure, meshing precision, high efficiency, output torque is constant. Aluminum alloy cylinder block, piston and end cover, and the lighter weight compared with the specification of the structure of the actuator. For the extrusion of aluminum alloy cylinder body, and the hard anodic oxidation treatment, the inner surface quality of a material is solid, strength, high hardness. Low friction material of sliding bearing is adopted to avoid the direct contact with each other between the metal, low friction coefficient, flexible rotation, long service life. Pneumatic actuators and valve installation, connection size according to the international standard ISO, DIN, and VDI/VDE design, are interchangeable with ordinary pneumatic actuators. Air hole in accordance with NAMUR standard. Pneumatic hole bottom of shaft assembly ( Meet ISO standard) Double square, facilitate with linear or ° Angle valve installation of square bar. The top and at the top of the hole of the output shaft in accordance with NAMUR standard. Adjusting screw can be adjusted at the ends of the valve opening Angle. The same specifications of a double-acting and single acting ( Spring return) 。 Can choose direction, according to the requirements of the valve clockwise or counterclockwise. According to user need to install the solenoid valve, the locator, The opening instructions) , letter opener, all kinds of limit switch and the manual operation device. Pneumatic actuators, accept the advantages of continuous gas signal, output linear displacement ( After add electricity/gas conversion device, also can accept the continuous electrical signal) , some with rocker arm, but the output angular displacement. Pneumatic actuators, is, reaction function. , movement speed, but the load is increased speed will slow down. Related to the operating pressure, output force. , high reliability, but after air break valve cannot keep ( After the position control valve can keep) 。 Implement piecewise control and program control, the inconvenience. And maintenance simple, good adaptability to environment. And the output power is larger. , with explosion-proof function.
