Fuxi Intelligent Adjustment Positioner

Fuxi Intelligent Technology is committed to providing customers with comprehensive solutions based on intelligent IoT technology. Our company aims to consolidate the development of ubiquitous power IoT in industry resource sharing, cooperation and win-win, forming a synergy of technological innovation and product creation, driving the common development of the upstream and downstream of the enterprise industry chain, and jointly building an open, co built, cooperative and mutually beneficial energy ecology.

Fuxi Intelligent Adjustment PositionerThe microprocessor sends switch commands to the electrical conversion module based on the deviation of the 4-20mA control signal and valve position feedback, causing a change in the output air flow rate and driving the valve to change its opening. When the opening reaches the required position, the piezoelectric valve has no output, stabilizing the valve at that position. CVX adopts a new piezoelectric valve principle electrical conversion technology and uses German imported electrical conversion modules; Ultra low power consumption, up to 2 billion switches, steady-state gas consumption less than 36L/h, far less than conventionallocator400L/h.

The gas interface, gas molecular sieve, and new generation piezoelectric valve greatly enhance the ability to adapt to particulate matter in compressed air, reaching ISO8573-1 particle level 4, oil level 4 standards, dew point standard 10K; reaching the standard of nozzle baffle. 2/2-way cone valve design, characterized by no leakage, high durability, and short response time, with a lifespan of up to 4 million times and a response time of 6ms-25 "C. Low temperature stability improvement is provided, with an optional module of -40" C

The piezoelectric pilot valve has established an additional diagnostic function reserve and can achieve 13 self diagnostic functions

Fuxi Intelligent Adjustment PositionerUsing neural network control algorithm, the stroke is divided into n segments, optimizing more suitable compensation pulses, suitable for use at gas source pressures of 1.4 bar~7 bar. Adopt self-tuning method for pneumatic actuators of different volumes, configure different control parameters, and adapt to pneumatic actuators of different volumes. By recording the pulse changes at different temperatures through experiments and analyzing the data, a temperature pulse correction formula was fitted, and the output value was the sum of the normal calculated value and the correction value. Combined with a wide temperature characteristic electrical conversion module, it adapted to different temperature conditions by adding a prediction zone. When the control deviation entered the prediction zone, the deviation change rate was monitored, and the reverse pulse was activated in a timely manner to adapt to large inertia load valves, such as chemical heating furnace air door baffles.

Adopting initial pulse control, neural network control algorithm, segmented stroke, suitable for high friction valves such as oxygen valves
