Specific embodiment
Technical solution of the present invention is further illustrated below in conjunction with attached drawing:
The system and device is that design has fluidised form regulation module, temperature regulation on the basis of former self-loopa open channel experimental provision
Module and water level management module.Wherein fluidised form regulates and controls module by self-loopa open channel sink A, electromagnetic flowmeter B2, flow regulator
B3, electric control valve B4, recorder C composition；Temperature regulates and controls module by temperature sensor D2, heating, refrigeration instrument D4, recorder
C, temperature controller D3 is formed；Water level management module by liquid level sensor E1, water-delivery pump E2, pressure switch E3, indicator lamp groups at.
1, fluidised form regulation module is to need to set target flow, electromagnetism by flow regulator B3 to fluidised form according to experiment
Aqueduct flow signal can be conveyed in real time flow regulator B3 by flowmeter B2, and flow regulator B3 believes the flow received
Real-time display and record are carried out on Real-time Feedback to recorder C number again, (such as centrifugal pump B1 is for a long time when external condition changes
There is fatigue phenomenon in work, and flow can reduce), flow regulator B3 understands automatic trigger electric control valve B4 for flow enhancement to original
Beginning setting value.
2, temperature regulation module is to need to set target temperature, water storage by temperature controller D3 to temperature according to experiment
Temperature signal real-time transmission to recorder C can be carried out real-time display and record by temperature sensor D2 by the water temperature in the A9 of pond,
Recorder C influences water temperature when external condition changes on the temperature signal received again Real-time Feedback to temperature controller D3
When, temperature controller D3 can the temperature was then adjusted to original set values automatically by the instrument D4 that heats or freeze.
3, water level management module is to need to set target water level pressure, liquid by pressure switch E3 to water level according to experiment
Level sensor E1 can be by reservoir A9 hydraulic signal Real-time Feedback to pressure switch E3 and recorder C, when pressure switch E3 is received
(such as water evaporation loss of reservoir B2) pressure switch E3 can flash the redlight and open when being lower than normal hydraulic pressure to hydraulic pressure, at this time
It will pass through water-delivery pump E2 to start to be automatically replenished water source, when liquid level sensor E1 experiences original start hydraulic pressure, pressure switch E3
Green light can be lighted and water source is automatically closed.
After the experimental system opens power supply, only needs manually to set corresponding flow, temperature and water level in control terminal, try
