Product description
Straight stroke electric actuator is used to drive single and double seat control valves, sleeve valves, high temperature and high pressure, water supply, desuperheated water, etc. Linear displacement regulating valve.
1. It is an intelligent control system.
The series of intelligent motor actuators, on the premise of fully absorbing the advanced technology of similar products at home and abroad, and based on the characteristics of my country's industrial control system, use modern single-chip microcomputer technology to complete various functions with the reliable single-chip microcomputer as the core. Various controls and functions are completed by software programs.
2. It is a fully functional control system.
. Broken signal protection function: When the input signal is less than There are three preset modes: home position, fully open, and fully closed.
. Over-current protection function: When the actuator has over-current, the control circuit of the machine automatically closes and the actuator remains in place to protect the actuator and valves.
. Dynamic electric braking function. When the motor runs to the given feedback value, the output shaft will oscillate due to the inertia of the operation. At this time, the software program issues a dynamic electric braking command (that is, an instantaneous reverse current is given), causing the sweeping mechanism to stop running immediately without idle oscillation, which greatly improves the reliability and stability of the automatic adjustment system. sex.
The upper and lower limit limit functions are based on the needs of the site. The angular stroke is within the range of degrees, and it is basically within the rated stroke range. The upper and lower limits are adjustable at will, and the adjustable range is left and right. When leaving the factory, the lower limit is set to and the upper limit is set to
3. It is a control system with high reliability and stability.
The selected series of microcontrollers have powerful functions and high reliability. It integrates central controller,,/mouth into one. Since external leads are eliminated, the possibility of being affected by interference is almost zero. Compared with similar products with conventional circuits, it has the characteristics of compact structure, fewer components, small size, easy adjustment, low failure rate and high stability. In addition, because the microcontroller uses single-byte instructions, the confusion between operation codes and operands is eliminated, further improving stability. Otherwise, the program will be burned and the software design has added a watchdog (this watchdog circuit works independently in the microcontroller and is not affected by the clock and circuit), which fundamentally eliminates the occurrence of microcontroller crashes. Therefore, , this system is a very reliable system. Based on the above, the series of intelligent electric actuators are advanced models of the era and are upgrades of traditional products.
