Electric actuators electropneumatic valve application resolution let more customers benefit

electric actuators, also known as electric actuators. It is a kind of can provide device driven by linear or rotary motion, it USES some kind of drive energy and work under the action of a control signal.
advantage is energy use is convenient, signal transmission speed, long transmission distance, facilitate centralized control, high sensitivity and precision, cooperate with electric monitoring instrument is convenient, installation simple wiring.
with the function of relative to the hydraulic and pneumatic products, electric actuator is the highest cost performance. Electric actuator ( Electric putter/electric cylinder cleaner, more convenient operation, higher power efficiency, the user can benefit. Electric actuators integrated design easier to control programming, maintenance work reduced to minimum, unless in extreme conditions, without lubrication replacement parts.
defect is complex, the thrust is small, the average failure rate higher than the pneumatic actuators, suitable for explosion-proof requirements is not high, lack of air. Main characteristic

structure design, integration, position transmitter and servo amplifier as two independent components can be directly into the actuator, directly to - MA control signal, the output - MA or - VDC pneumatic valve position feedback signal, has the self-diagnosis function, use and adjustment is very convenient.
, function modular structure design, through the combination of different optional features, from simple to complex control, meet different application requirements.
, simple structure, small volume, light weight, easy installation and maintenance, mechanical parts are all made of CNC processing production, exquisite workmanship.
and transmission are all made of small gear backlash seal, high efficiency, low noise, long service life, stable and reliable, do not need to add oil, etc.
and have a variety of speed, can meet the requirements of all kinds of control system, to ensure rapid response and stability of the system.
, PSL series connection using the flexible disc spring connection with pneumatic valve, pneumatic valve stem can avoid with the output shaft is not concentric to the impact of the pneumatic valve, pneumatic valve can be preset shut off the power to ensure reliable pneumatic valve shut off, to prevent leakage.
, drive motor adopts high performance rare earth magnetic material production of high-speed synchronous motor, smooth operation. With small size, large torque, locked-rotor resistance, high control precision, etc.
, can adjust Settings section, namely the double time scale by a regulator output signal to control two actuators ( - MA corresponding PSL is wide open, full close - MA open full close for the PSL.
, pneumatic valve position feedback element is fully sealed high precision ring potentiometer, has small volume, high precision, small dead zone, long service life, etc.
, adjustable stroke, facilitate with pneumatic valve connection.
, all electrical components adopt world famous brand products, reliable quality, long service life.
wiring, electrical components is rigorous and completely isolated from driving part, improves the executing agency run reliably. The structural characteristics of the

the reporter understands, PS series electric actuator components wiring is rigorous and completely isolated from driving part, improve the reliability of the actuator operation, transmission part adopts CNC machining small backlash sealed gear drive, with high efficiency, low noise, long service life, stable and reliable, not because the process environment, such as medium entrance force actuator resonance caused by the fluctuation, etc.
PSL straight travel actuators is mainly controlled by the isolated electrical part and gear transmission parts. Motor as two isolated part of the middle connection parts, motor output torque, according to the requirements of control by multipolar spur gear is passed on to the trapezoidal screw, screw for thrust through commutation torque rod threads. The stem threads can be self-locked, and transfer line trip through the adapter with pneumatic valve to the pneumatic valve stem. Enforcement agencies out of the shaft with a check diversion, prevent the rotation of the shaft radial locking devices can be used as a position indicator. Locking devices connected to a connecting rod, connecting rod with the output shaft synchronous operation, through the circuit board with connecting rod connected to the output shaft displacement is converted into electrical signal, and provided to the servo amplifier as pneumatic valve position feedback signal and the output, at the same time, the stroke of actuators can be made of two main switch board limit switch to limit, and the two mechanical limit block to adjust the limit position.
