Analysis of common problems in the use of Yudian intelligent PID controller


The intelligent PID controller produced by Yudian Automation Co., Ltd. is fully functional and can be configured for output requirements in different occasions. It is widely used in many industries. Common control actuators include relays that receive switching quantities, solid state relays (SSRs) that receive high and low voltage levels, frequency converters and valves that receive analog signals, or direct control of thyristors. Among them, the control thyristor is divided into zero-crossing trigger and phase-shifting trigger, the difference between the two is whether the power control can be realized.

Yudian intelligent PID controller has two adjustment modes: standard PID and AI artificial intelligence adjustment APID. It has self-tuning self-learning function, which can achieve excellent control characteristics without overshoot and no undershoot. However, in some special occasions, such as controlling the valve, the customer sometimes needs to manually adjust the output. In this case, the controller needs to have the automatic hand switching function. In order to meet the different requirements of customers, Yudian has launched the AI-519/AI-719 intelligent PID controller with automatic hand-free disturbance switching function, convenient manual operation and simple switching mode. For the valve, it is generally receiving the analog signal. The valve is divided into a proportional valve and an inverse proportional valve. Many customers will ask if the output of the meter can correspond to the positive and negative valves. Yudian Xiaobian pats the chest to assure you that as long as it is the intelligent PID controller of the U-power control valve, all have positive and negative reaction adjustments, you can choose the positive and negative effects according to the positive and negative valves.

Chromium Carbide Overlay plates used in so many industries.Wear Resistant Steel Plate finished by auto machine,so all plates are easy to cut and weld.So they are widely used in everywhere.Because of its good wear resistant and good price,they have accepted by some areas.


(1) the cement industry, powder concentrator's blade mixer blade, what smooth operation platform, the mill liner, inlet cone, transporting pipe, the sieve plate, bin, chute, the repair of cement vertical mill, etc.
(2) fan industry: fan impeller, cyclone separator, fan blade, back plate liner, fan machine mouth, easy wear parts, etc.
(3) the iron and steel metallurgy, material chute, bunker lining board, slippery slope, mesh screen, drum wind bell jar, skip, boiler drum boiler wind reinforced steel, sinter feed tube, pipe, distribution board, slag trough, exhaust fan, high burden of tank lining board, coke dry quenching tank lining board, coke pusher plate skateboard floor, block coke car lining board floor, sintering machine of single roll crusher, scraper, water beam and wall repair production, etc.
(4) coal industry: the cone wear-resisting lining of the wheel bucket excavator, the middle slot of the scraper, the feeding trough, the hopper, the coal mine lifting skip, the pipe of the coal washing plant, the chute.
(5) power machinery: fan impeller, coal ash pipe, silo, feeding trough, coal conveying parts, hopper lining, medium speed grinding coal mill, burner nozzles, etc.
(6) other industries: solar glass, mining machinery, construction machinery, coal machinery, fan manufacturing, wear-resisting brick, sand bin liners in the coal industry of mining, scraper conveyor plate, screen plate, etc.
(7) directly provide the user with the surfacing plate, and the user can make the material by himself, and complete the site construction projects, such as warehouse, chute, bucket, dump equipment, etc.
(8) according to the size of the wear area of the user parts, provide the guide for the maintenance of the spot welding, reduce the on-site welding workload, such as the shovel bucket of work machinery and dredger bucket of dredger.
