Electrical components of electronic electric actuator are strictly wired and completely separated fr…

One, the introduction:
PS series electronic electric actuator wiring electrical components 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, by process conditions, such as medium entrance force actuator due to fluctuation of resonance, etc.
Second, the widely used:
PS series electronic electric actuator is selected automatically control unit instrument, combined into a system control unit.With ASD electric servo manipulator to realize automatic remote manual control and hands/two-way switch without disturbances.This series of electric actuators can be widely used in power plants, steel mills, chemical industry, light industry and other industrial department of the production process automatic control system.
Three, the structure:
1, PSL straight travel electronic series electric actuators, based on 220 v ac single-phase power as driving power, from computer controller or operator of 4-20 madc, or 1 to 5 VDC input signal to the functioning of all electronic actuator, machine with servo system, without the other match servo amplifier, key components "controller" advanced hybrid integrated circuit, and resin casting solidification, the aging treatment, high reliability, moistureproof, shock.Use potentiometer to adjust zero, stroke, sensitivity, convenient and easy;In this paper, the function of switch is, in any action, and the choice of fault signal three states.At the same time, the execution has overload protection, temperature protection and compression spring to ensure that the valve is locked, etc. The three kinds of protection function.Is one kind has the high reliability of product, but with different Angle of straight stroke and stroke regulating valve of electric control valve.
2, PSQ quarter-turn electronic series electric actuator is 220 v ac single-phase power for driving power, the input signal using the 220 v ac switch, motor adopts ac reversible phase geared motor, opening detection precision conductive plastic locator, but with different Angle of straight travel and travel adjustment valve switch controlling the electric actuator.
Four, the main features:
1, the integration structure design, position transmitter and servo amplifier as two independent components can be directly into the executing agency, directly to 4-20 ma control signal, 4-20 ma, or 1-5 VDC output valve position feedback signal, has the self-diagnosis function, use and adjustment is very convenient.
2, the function modular structure design, through the combination of different optional features, from simple to complex control, meet different application requirements.
3, simple structure, small volume, light weight, easy installation and maintenance, mechanical parts are all made of CNC processing production, exquisite workmanship.
4, drive all adopt the small gear backlash seal, with high efficiency, low noise, long service life, stable and reliable, no need to refuel, etc.
5, has a variety of speed, can meet the requirements of all kinds of control system, to ensure rapid response and stability of the system.
6, PSL series connected with the valve adopts flexible coil spring connection, can avoid the valve stem and the influence of output shaft misalignment brings to the valve, the valve can be preset shut off the power to ensure reliable valve shut off, to prevent leakage.
7, PSQ series torque switch protection, can prevent the damage due to valve is too large torque of valve stem.
8, 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.
9, can adjust Settings section, namely the double time scale by a regulator output signal to control two actuators (4-12 ma corresponding to the full open and full closed PSL1, 12 to 20 ma corresponding PSL2 full open and full closed).
10, valve position feedback element adopts full seal precision ring potentiometer, has small volume, high precision, small dead zone, long service life, etc.
11, adjustable stroke and easy to connect with valve.
12, all electrical components adopt world famous brand products, reliable quality, long service life.
13, electrical components, wiring is rigorous and completely isolated from driving part, improves the executing agency run reliably.
