The course of work of the energy saving regulator control system of pipe network dynamic load intelligent pressure regulating difference provided by the utility model is as follows:
Embodiment 1:
For heat exchange station before operation, control centre remotely issues heat exchange station secondary water-supply desired temperature to field controller,
Electric control valve K1 is given according to controller, adjusts electric control valve K1 aperture, it is therefore an objective to make secondary water-supply temperature thermal resistance PT
Or primary side flowmeter value of feedback reaches the secondary water-supply temperature or primary side flow setting value that controller receives.
The secondary water-supply temperature that controller receives is not achieved in secondary water-supply temperature thermal resistance PT or primary side flowmeter value of feedback
Degree or when primary side flow setting value, electric control valve K1 is gradually opened, when electric control valve K1 aperture is to maximum value, such as
Aperture 98% continues 10 minutes, secondary when still reaching to for temperature less than temperature value is issued, and prepares starting primary side pipeline pump W.At this time
Electric control valve K1 keeps maximum opening constant, closes bypass electric valve K3, meanwhile, a side ducts are started by frequency converter
W is pumped, when frequency converter frequency reaches 30Hz, pump discharge electrically operated valve K2 is opened, at this point, control object is set as becoming by controller
Frequency device.Frequency converter sets minimum running frequency as 35Hz, when 35Hz is run, such as heat exchange station secondary water-supply temperature thermal resistance PT at this time
Or primary side flowmeter value of feedback meets the secondary water-supply temperature or primary side flow setting value that controller receives, then frequency converter control
Primary side pipeline pump W processed keeps existing frequency operation；Such as heat exchange station secondary water-supply temperature thermal resistance PT or primary side flow at this time
Meter value of feedback is still below the secondary water-supply temperature or primary side flow setting value that controller receives, then frequency converter raising frequency is run, directly
Meet the secondary water-supply desired temperature that controller receives to secondary water-supply temperature thermal resistance PT or primary side flowmeter value of feedback,
Then Frequency Converter Control pipeline pump keeps the frequency to run；Such as heat exchange station secondary water-supply temperature thermal resistance PT or primary side flow at this time
Meter value of feedback is higher than the secondary water-supply temperature or primary side flow setting value that controller receives, then frequency converter keeps 35Hz operation,
Controller control object is switched into electric control valve K1 from pipeline pump frequency converter, gradually turns down electric control valve K1 aperture, until
Secondary water-supply temperature thermal resistance PT or primary side flowmeter value of feedback meet the secondary water-supply temperature or primary side that controller receives
Flow setting value, electric control valve K1 keep aperture constant.
It is more than 30 minutes when electric control valve K1 aperture is lower than some opening value, such as aperture is less than or equal to 30%, then it is quasi-
It is standby to close primary side pipeline pump W.Pump discharge electrically operated valve K2 is automatically closed first, then Frequency Converter Control primary side pipeline pump W
Termination of pumping, meanwhile, bypass electric valve K3 is opened, controller adjusts aperture, make secondary water-supply temperature by control electric control valve K1
Degree thermal resistance PT or primary side flowmeter value of feedback reach the secondary water-supply temperature or primary side flow setting value that controller receives.
Wherein, judge value a little, be designed as live to set, field adjustable sets optimum value by actual motion.
System can automatic running can also be by remotely or on the spot manually controlling start and stop in the manner described above.
