Abstract
The utility model relates to a state control device for a fan air door openness actuator. The state control device for the fan air door openness actuator is characterized by comprising a DCS (Distributed Control System), an intermediate relay, a contactor, a power supply, a manual overhauling switch, an actuator and a fan air door, wherein the intermediate relay is connected with the position given signal output end of the DCS, the contactor is connected with the output end of the intermediate relay, the power supply is connected with another input end of the contactor, the manual overhauling switch is connected with the power input end of the contactor, the actuator is connected with the power output end of the manual overhauling switch, the fan air door is connected with the actuator, the other input end of the actuator is connected with the position given signal output end of the DCS, and the feedback signal output end of the actuator is connected with the position feedback signal input end of the DCS. The state control device for the fan air door openness actuator has the advantages that when a fault judgment program of the DCS is judged as a fault state, the DCS outputs a position given signal to the intermediate relay and then triggers the contactor to cut off the power supply of the actuator so as to stop the air door actuating, thus avoiding faults in fully-opened and fully-closed states of the actuator.
Description
Technical field
The utility model relates to boiler of power plant control technology field, relates in particular to a kind of air door of fan aperture actuator behavior control device.
Background technology
To lean on two throttle openings of continuous adjusting pressure fan and air-introduced machine to control the air pressure in the burner hearth during boiler of power plant operation, ensure full combustion of fuel.The realization of the employing of boiler operatiopn at present DCS control system controls two air doors, specifically is to actuator, through actuator control and regulation throttle opening through the given signal of automatic control system outgoing position.The working condition of two actuators is most important to the safe and stable operation of boiler.And actuator occurs not controlled by input signal at work sometimes, and the situation to a direction is rotated makes throttle opening complete shut-down and full-gear occur.This state can cause the urgent blowing out of boiler of power plant, fire extinguishing, burner hearth to beat malleation and high temperature furnace fire-fighting serious accident such as go out to hurt sb.'s feelings, and has had a strong impact on the safety of the person and equipment.Air door of fan aperture actuator behavior control device can effectively be avoided because of improper this type of accident that causes of throttle opening control.
Summary of the invention
The purpose of the utility model is to provide a kind of air door of fan aperture actuator behavior control device, stops actuator standard-sized sheet, full-shut position, effectively controls two throttle openings of pressure fan and air-introduced machine, avoids accident to take place.
The purpose of the utility model realizes through following technical proposals:
A kind of air door of fan aperture actuator behavior control device of the utility model; Comprise have the steam flow parameter, main vapour pressure parameter and position feed back signal input; Two given signal output parts in position; The DCS control system of fault judgement program module; It is characterized in that auxiliary reclay that described air door of fan aperture actuator behavior control device is connected by the given signal output part in position with DCS control system, the contactor that is connected of auxiliary reclay output therewith; The electrical source of power that connects of another input of contactor therewith, the manual inspection switch that connects of contactor power output end therewith, manually the actuator that is connected of inspection switch power output end is formed with the air door of fan that is connected with actuator therewith; Another input of described actuator is connected with the given signal output part in position of DCS control system, and described actuator feedback signal output is connected with the position feed back signal input of DCS control system.
The air door of fan aperture actuator behavior control device of the utility model; The given signal output part of its DCS control alliance is that actuator sends the given signal in position; A given signal controlling air door of fan of output executing location of actuator aperture; Another output outgoing position feedback signal of actuator to DCS control alliance feedback signal input, DCS control system handles steam flow parameter, main vapour pressure parameter, the given signal of position feed back signal and position and judges in the fault judgement program module of DCS control system.
The air door of fan aperture actuator behavior control device of the utility model; When the fault judgement procedure result that carries out when the fault judgement program module of DCS control system is normal condition; After actuator receives the given signal in position, air door is carried out aperture control, when fault judgement program judged result is malfunction; The DCS control system given signal in position that this is unusual is issued actuator; The given signal in simultaneously that this is unusual position outputs to auxiliary reclay, and auxiliary reclay removes to trigger contactor after receiving this given signal in unusual position, and contactor cuts off working power and makes the actuator dead electricity; And the control air door stops action; The motor that stops actuator is avoided actuator standard-sized sheet, complete shut-down status fault to a direction operation, and actuator feeds back to the concurrent alarm that is out of order of DCS control system with the out-of-the way position feedback signal of outage simultaneously.
The advantage of the utility model:
The utility model is installed and is easy to implement; When actuator is out of control in process of production; Through making the actuator outage; Avoided air door the complete shut-down full-gear to occur effectively, thereby avoided beating serious accidents such as malleation and high temperature furnace fire-fighting go out to hurt sb.'s feelings because of the urgent blowing out of the improper boiler of power plant that causes of throttle opening control, fire extinguishing, burner hearth.For safety in production provides reliable guarantee.
Description of drawings
Fig. 1 is the control block diagram of the air door of fan aperture actuator behavior control device of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1; The air door of fan aperture actuator behavior control device of the utility model; Comprise have steam flow parameter 12, main vapour pressure parameter 11 and position feed back signal input 10; The DCS control system 1 of two given signal output parts 2,9 in position and fault judgement program module; It is characterized in that auxiliary reclay 3 that described air door of fan aperture actuator behavior control device is connected by the given signal output part 2 in position with DCS control system 1, the contactor 5 that is connected of auxiliary reclay 3 outputs therewith; The electrical source of power 4 that connects of another inputs of contactor 5 therewith; The manual inspection switch 6 that connects of contactor 5 power output ends therewith; Manual therewith 8 compositions of inspection switch 6 power output ends actuator 7 that is connected and the air door of fan that is connected with actuator 7, described actuator 7 another inputs are connected with the given signal output part 2 in position of DCS control system 1, and described actuator 7 feedback signal outputs are connected with the position feed back signal input 10 of DCS control system.
