In the integrated application of constant pressure water supply automation products

In constant pressure water supply automation products integrated application of shenyang mechanical and electrical TBS detailed FAE cheng-zhi sun welcome to e exhibition hall hall hall 2 vacuum equipment/pump water pump, roots pump, screw pump, gear pump, centrifugal pump,. 。 。 Abstract: this article mainly tells the story of no negative pressure in automation products in the feed industry integration application in intelligent water supply system, this paper introduces the constant pressure water supply control system configuration and process, as well as in PLC, HMI application skills. Keywords: PLC man-machine interface macro instruction 1 introduction PID constant pressure water supply is mainly used in boiler, buildings, industrial buildings water supply, and many other water supply industry, the constant pressure water supply project belongs to the cliche, mature solution to control system, implementation method also is more, there are special microcomputer feed water control box, inverter PID control itself, man-machine interface and PLC integration applications, its principle and core control idea are the PID control model, negative pressure constant pressure water supply is realized. In this paper after a technical solution to realize constant pressure water supply, mainly reflected in integrated application technology solutions to provide customers perfect automation experience. 2 control system technical scheme configuration schedule list of original control system main control, other auxiliary electrical devices will not be here. Schedule element overview table 3 control system principle of PLC mainly using the PID instruction for constant pressure water supply control requirements, as shown in figure 1, 2. Figure 1 control system principle a) Figure 2 control system principle of b) 4 process control system and PLC program overview according to the given pressure equipment work requirements set system ( Mpa） As PID self-tuning control model of SV value, pressure meter sensor will be controlled object pipe ( Mpa） Real-time acquisition, as the PV value of PID self-tuning model, the numerical size deviation value is generated after Et, according to the proportional coefficient Kp and integral coefficient adjusted Ki Kd, differential coefficient, PID instruction result control output of PLC control program, MV values, converted to analog ( 0 ~ 10 v) As a frequency signal given, the control inverter output different drag pump motor speed, regulating water supply pipeline pressure control. Figure 3 pid instruction explanation as shown in figure 4. Figure 4 PID instruction parameter interpretation chart of PLC control program in the pipeline pressure reading part as shown in figure 5. Figure 5 line pressure part drawing in the PLC control program of PLC control program of collecting pipe pressure processing is shown in figure 6. Figure 6 in the PLC control program of collecting pipe pressure processing figure filter to remove 06 xa module to collect digital quantity value 0 ~ 4000, according to the pressure sensor and pressure transmitter range corresponding relationship to calculate the actual pressure pipeline ( MPa） Value. PID instruction using the method in the PLC control program are shown in figure 7. Figure 7 PID instruction using the method in the PLC controller control program figure PID instruction operation as a given frequency inverter output signal, and converting frequency value for man-machine interface display, as shown in figure 8. Figure 8 PID instruction transformation figure 5 man-machine interface of man-machine interface there are three main control picture: set parameters and real-time display, the pump running animation display, work mode selection, and other functions. Introduce as shown in figure 9, 10, respectively. Tutu 10 PID parameter setting figure 9 main picture tutu 11 pumps running animation dynamic display graph is worth mentioning that the pump is running animation display with a macro instruction to complete the man-machine interface, effect is not as luxury industrial control configuration software, the feast for the eyes, but also the running state of the industrial site real, to satisfy the customer's needs. Macro instruction is divided into three parts: CLOCK, macro 1, macro 2. CLOCK Macro according to two different pumps running status call SubMacro 1 and SubMacro 2 respectively, as shown in figure 12 and 13. Figure 12 SubMacro 1 SubMacro 2 is used to display the dynamic running water pump 2 animation display. Figure 13 SubMacro figure 2 146 summary of automation products successfully integrate application of constant pressure water supply project, the actual effect of constant pressure water supply well, fully meet customer demand, the user really sure in products, through the case to introduce mature and reliable technology solutions to offer to our customers, flexible application of man-machine, PLC and industrial control products, to provide customers the perfect automatic control product experience.
