Specific implementation mode
Utility model will be further explained below with reference to the attached drawings and specific embodiments, to help understanding that this practicality is new
The content of type.
As shown in figures 2-6, a kind of pipeline conditions monitoring system based on flabellum rotating speed feedback data, including input unit,
Control unit and output unit, the input unit is vane type air velocity transducer, recognizable according to flabellum rotary speed data is measured
Air hose state is normal, warning, blocks, to recognize pipeline conditions, to realize accurate preventative maintenance.
The vane type air velocity transducer circle diameter 1 is 12.5-13.5cm, and vane type air velocity transducer thickness 2 is
8.5-9.5cm, positive length 3 are 7.5-8.5mm, and cathode length 4 is 5.5-6.5mm, and distance 5 is 4.5-5.5mm between positive and negative anodes,
Positive and negative anodes thickness 6 is 0.7-1.7mm, realizes measuring and calculating location dislocation≤5mm, the target of error≤1.7%.
Described control unit is Siemens S7-PLC, and stability is acted in 100%, control response time≤0.1S
It is required that it is similar to receive signal in daily control.
The output unit includes alarm, field panel and long-distance monitorng device, and the alarm is LTE-1101J
Audible-visual annunciator, the field panel are LED digital display screens.Wherein alarm find alarm and occur alert the time≤
10S, LED digital display screen response time≤0.1S, the long-range information time that receives is≤0.5S
As shown in figure 5, the alarm includes power supply 7, control unit feedback signal receiving terminal 8, loud speaker 9, loud speaker
Loudspeaker 10, alarm lamp 11 and warning lamp 12, digital display screen connect loud speaker and alarm lamp simultaneously.
Now with regard to vane type air velocity transducer installation site example, range is choosing best position in 0~30m/s
When, circle diameter is the central point of 200mm, its position is determined with golden section point.Mounting height selection range be 0~
200mm, set objective are >=95%.P1=(200-0) × 0.618+0=123.6mm, testing site P2=0+200- in testing site
123.6=76.4m is tested through 4 times, and average accuracy does not all reach set objective, but P1 is better than P2；Second of experiment exists
76.4~200mm chooses testing site, and testing site P3=(200+76.4) -123.6=152.8mm is compared with P1, and P3 does not reach equally
