Electric Actuator

Description

1, Housing:hard-anodized AL alloy and external coating of epoxy power is suitable for the severe condition especially against the corrosion.Housing is designed in accordance with standard of Explosion-proof and IP*7.And also we can offer JINGLU EQS with IP*8 for option. 2, Motor:specilly designed with squirrel caged induction motor to generate high starting torqur and high efficiency equipped with thermal protector to prevent damage from over ***** has several features such as high output power.high efficiency and lower noise. 3, PCU:high performance microprocessor, auto-calibration provides the most convenient to user without complicated set in field. 4, Sealing:sealing provided by double O-ring system. 5, Handwheel:Just by pulling over the level, operating mode is switched to manual, then just supplying electrical power to actuator, clutch is automatically disengaged from manual and operating mode is switched to electric ***** size of hand wheel is designed according to required torque to move the actuator, so that operator can easily move the actuatorby hand. 6, Gear&self locking:2nd staged double worm gearing prevents movement caused by backward force transferred from valve and it provides the exact and stable position of actuator and valve when the power is off, High efficiency, high output torque, low noise level areanother advantages. 7, Limit switches:directly engaged with driving shaft to setaccurate position of ***** switches:to protect actuator from damage caused by over torque from the driven valve the whole travel. 8, Anti-condensation space heater:the switch is open when the temperature is around*0±3 to prevent over heating. 9, Stopper bolt:stopper bolt installed both close and open direction prevents actuator&#**9;s travel over the limit during manual operation and also protects internal gearing from its breakaway. *0, Indicator:through the large size indicator window providesbetter position indication from a distance. *1, Terminal block:it is easy to add the number of strip for additional connection, spring loaded terminal strip is very strong against vibration. *2, Wiring:the inside wiring is so simple and easy to connect. *3, Driving bushing:the driving bushing is removable to process, mounting base is designed according to ISO***1, it is convenient to adapt with valve. *4, Lubrication:all the gears and shafts use CIATM**1 type Grease Moly, it is not necessary to refill lubricant for 5 years. *5, Anti-interference magnetic loop:it effectively prevents the actuator from outside magnetic field, and keeps the actuator operating stable.
