Description
Technical field
The invention belongs to a kind of device that can produce regime flow.
Background technique
Usually the method that produces regime flow is: give an airtight tank body pressurization by high-pressure water pump, again by the valve of an adjusting angle, regulate the flow of setting with this valve.There is following defective in said apparatus: airtight tank body pressure is influenced by the flow size, and tank body pressure fluctuates, and causes flow control also along with pressure surge.Flow can not be adjusted to the flow of setting accurately, and especially flow is less and flowed fluctuation is bigger, and energy consumption is excessive, no matter need great flow, high-pressure water pump is running at full capacity all the time.
Summary of the invention
The object of the present invention is to provide a kind ofly can provide accurately, regime flow and steady flow device easy to use.
The technological scheme that adopts is:
A kind of flow stabilization apparatus comprises water pump, surge tank, pressure transmitter, proportion valve, standard scale, frequency variator and computer.
The liquid outlet of water pump is connected with the liquid entering hole of surge tank by pipeline, and the liquid outlet of surge tank is connected with the liquid entering hole of proportion valve by pipeline, and the liquid outlet of proportion valve meets the user by management.
The liquid entering hole of pressure transmitter is connected with the liquid outlet of surge tank, is equiped with standard scale on the output pipe of proportion valve.
The signal output of pressure transmitter is connected with the corresponding interface of computer by lead respectively with input terminal.
The FM signal output terminal of frequency variator is connected with the FM signal input terminal of the frequency modulation motor of water pump by lead, and the FM signal input terminal of frequency variator is connected with the corresponding interface of computer by lead.
Frequency variator, water pump, surge tank, standard scale, ratio adjusting valve door and pressure transmitter are connected in turn on the pipeline, frequency variator, pressure transmitter, computer and ratio adjusting valve are as pressure controlled feedback loop, the pressure of control surge tank, pressure transmitter is connected the outlet of surge tank, change the rotating speed of water pump and the opening angle that changes proportion valve by the computer control frequency variator, so that reach the stable of surge tank pressure, finally reach the purpose of regime flow.
The working principle of flow stabilization apparatus of the present invention is:
Start pump motor, pump working is sent into liquid medium in the surge tank, and flows out through the liquid outlet of surge tank, exports through proportion valve.Simultaneously, pressure transmitter obtains the surge tank internal pressure, and this signal sent into computer, send control command signal as calculated after the processing of machine to frequency variator, frequency variator sends control signal then, regulate the frequency modulation motor rotating speed, revise the Control Parameter of frequency variator and the angle that the proportion valve under the control of corrected Calculation machine is opened by the pressure of pressure transmitter feedback, water pump produces different rotating speeds under the control of frequency variator, the angle of passing ratio valve opening produces pressure, pressure transmitter compares pressure and the system works setting pressure that detects, the pressure error that produces is provided regulated quantity after the machine processing as calculated, change the rotating speed of water pump and the opening angle that changes proportion valve by the computer control frequency variator,, finally reach the purpose of regime flow so that reach the stable of surge tank pressure.
The present invention has the advantage of Flow-rate adjustment precision height, stability of flow, energy saving, high working efficiency.
