Yang Jian power electronic actuator PSL312 thrust 12000;
PSL, PSQ GmbH PS series electronic actuator can be used to adjust and control the opening and closing of the pipeline valve and damper, its main features are as follows: (1) the integration of structure design, position transmitter and servo amplifier as two independent components can be loaded directly inside the actuator, directly accept the 4-20mA control signal. Output 4-20mA or 1-5VDC valve position feedback signal, with self diagnostic function, is very convenient to use and adjust. (2) functional modular structure design, through the combination of different optional functions, to realize the control from simple to complex, to meet the different application requirements. (3) the structure is simple, small size, light weight, easy to install and maintain, mechanical parts are all processed by CNC, exquisite workmanship. (4) all of the small gear transmission gap seal, has the characteristics of high efficiency, low noise, long service life, stable and reliable, no need to add oil etc.. (5) it has a variety of operating speed, can meet the requirements of various control systems, in order to ensure the rapid response and stability of the system. (6) connect the PSL series with the valve spring by flexible connection, can avoid the influence of different valve stem and the shaft to the output shaft, preset valve closing force to ensure reliable off valve off, prevent leakage. (7) PSQ series has torque switch protection, can prevent the valve caused by excessive torque and damage to the stem. (8) the high speed synchronous motor made of high performance rare earth magnetic material is used in the driving motor. It has the characteristics of small volume, high torque, anti blocking and high control precision. (9) can be set by a double step adjustment, the proportion of time signal regulator output to control the two actuators (4-12mA PSL1 corresponding to the open fully closed, fully open the corresponding 12-20mA PSL2 closed). (10) the valve position feedback component adopts the full sealed high precision multi circle potentiometer, which has the characteristics of small size, high precision, small dead zone and long service life. (11) adjustable stroke, easy to connect with the valve. (12) all electrical components are well-known products, reliable quality, long service life. (13) the wiring of the electrical components is rigorous and completely separated from the drive parts, which improves the reliability of the operation of the actuator.
Two, product structure
PS series actuator wiring electrical components in rigorous and completely isolated from the transmission parts, improve the reliability of the actuator operation, small gap transmission parts processed by adopting CNC sealed gear transmission, has the advantages of high efficiency, low noise, long service life, stable and reliable, not because of the process environment, such as the media entrance the fluctuation characteristics of executive force resonance mechanism.
1.PSL straight stroke actuator PSL straight stroke actuator is mainly composed of isolated electrical control part and gear drive part. The motor is used as the intermediate part of the two isolation part, the motor output torque according to the control requirements, and is transmitted to the trapezoidal screw rod through the multi polar positive gear. The screw rod is changed into torque by the screw thread of the rod. The rod thread can be self locked and the straight stroke is passed to the stem through the adapter of the valve. The actuator shaft has a stop pin to prevent rotation, and the radial locking device of the shaft can be used as the position indicator. The locking device is connected with a connecting rod, the connecting rod with the output shaft of the synchronous operation, the output shaft displacement is converted into electrical signals through the circuit board is connected with the connecting rod, provided to the servo amplifier as the output signal and valve position feedback, and the actuator stroke can be composed of two main switch board switch to limit by two mechanical limit block to adjust the limit position.
2.PSQ angle travel actuator PSQ angle travel actuator is mainly composed of isolated electrical control parts and gear drive parts, and the motor is used as the intermediate part to connect the two isolation parts. The motor torque is transmitted to the planetary gear through the main gear, and the main gear drives the planetary gear to drive the hollow gear. The hollow gear three teeth less than two gear, so it can be driven by planetary gear, planetary gear rotation of the hollow gear three gear, external planetary gear meshing has a worm gear, the runtime does not separate, this design makes the increase in motor fault or valve torque can be directly carried out manually through the hand wheel control. The actuator has two thread stop mechanism limit, there are two limit switches to achieve power limit, each steering range can be controlled by the limit switch position, the valve opening by a projection display indicator, torque switch unique can be adjusted from 50%-100% maximum torque, torque protection, to prevent the valve was stuck by stem damage. Three, product selection
PS series electronic integrated electric actuator has small size, light weight, strong function, servo amplifier can be built-in, easy to operate, can be widely used in the pipeline valve, throttle switch control and adjustment control.
