Description
Technical field
The present invention relates to a kind of pump loop system, more particularly to a kind of pump loop voltage stabilizing reponse system.
Background technology
In the process of running, each parameter of circuit system needs to keep stable pump, is so favorably improved the operation of pump
Stability, the service life for extending pump.
With continuing to develop for industrial and agricultural production, pump loop system is increasingly applied to agricultural drainage and irrigation, municipal plumbing, fire
Periodical feeding, process feedwater and regional water transfer in electricity, nuclear power, petrochemical enterprise.Pump operation loop it is main by pump in itself,
The parts such as pipeline, measurement apparatus, control valve class, stabilization control device are constituted, and control valve class, stabilization control device are pump operations
The important component in loop, is directly connected to the stability of the parameters such as pump loop pressure, flow and lift, is also direct relation
To the stability and security of pump operation.And the stabilization of pump loop pressure is to directly affect the key of loop security and stability to ask
Topic.
Reponse system is not present in the pump loop system of prior art in terms of pressure monitoring, when the pressure of reserved node occurs
During change, have no idea that it is carried out to adjust automatically, in time, destruction damage of such pressure change to pump is larger, for example
The problem of water hammer.
A kind of service life length and anti-pipeline are disclosed in the Chinese invention patent that Application No. 201410035196.8
The lime set pump loop of erosion, this improved method is that lime set pump discharge installs minimum flow valve additional, not only reduces energy consumption, is led to simultaneously
Smooth backflow also alleviates erosion of the medium to pipeline significantly.In the Chinese invention patent that Application No. 201310521931.1
A kind of hydraulic control device of bidirectional plunger variable pump is disclosed, the hydraulic means for belonging to control bidirectional plunger variable pump is aimed to provide
A kind of output variable for ensureing bidirectional plunger variable pump is by the control device of linear change, and this improved method has variable defeated
Go out the advantages of steady, reliability is high, middle position is easy to adjust.But the improvement of two kinds of pump loops in above-mentioned patent all without reference to
To improved method of the pressure change to the destruction of pump loop.
For above-mentioned defect, the present inventor has invented a kind of design method of pump loop voltage stabilizing reponse system,
A circuit pressure feedback control device is with the addition of on the basis of original loop, the structure in whole pump operation loop is not only gived
Design method, alleviates pump loop operation unstability sex chromosome mosaicism, it is ensured that the safety and stability in pump operation loop also in certain degree
Operation.
The content of the invention
In order to solve the above problems, the invention provides a kind of pump loop voltage stabilizing reponse system design method.By improving
The structure in pump operation loop, adds pressure feedback system, improves the stability of pump loop operation, reaches extension pump and correlation
The purpose of the service life of part.
Realizing the technical scheme that above-mentioned purpose is used is：
1st, the voltage-stabilizing system is main by pressure boundary (1), (7), (8), pipeline (2), control valve (3), (5), (6), (10),
Pump (4), vacuum tank (11), feedback controller (9), (12) ten two part compositions, it is mainly characterized by：In pump operation loop,
It is feedback controller (12) respectively in the presence of two feedback control loops, control valve (3), node e, and pressure boundary (7)；And
Another loop is vacuum tank (11), feedback controller (9), node f, control valve (10) and pressure boundary (8).By to returning
The regulation of the feedback of road pressure and switch size to control valve, then the main flow of pipeline is adjusted, to maintain back
The pressure size on road.
2nd, when the node e in pump operation loop pressure changes, in order to maintain the pressure of pressure boundary (7), instead
Feedback controller (12) will control the flow of main flow section to maintain pressure boundary (7) to be adjusted on the switch of control valve (3)
Pressure, it is excessive or too small cause unnecessary loss to prevent control pressure.
3rd, when the node f in pump operation loop pressure changes, in order to maintain the pressure of pressure boundary (8), instead
Feedback controller (9) is maintained the switch of control valve (10) is adjusted come the flowing for the inner stream flow for controlling vacuum tank (11)
The pressure of pressure boundary (8).
According to above-mentioned steps, a kind of pump loop voltage stabilizing reponse system design method can be obtained.
The primary structure of pump operation backfeed loop is determined by the above method, mainly by pressure boundary (1), (7), (8), pipe
Road (2), control valve (3), (5), (6), (10), pump (4), vacuum tank (11), feedback controller (9), (12) ten two part compositions
It is mainly characterized by：On the basis of original pump operation loop, pressure feedback regulating system is with the addition of, carrys out the pressure of control loop
Change.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and detailed description.
Fig. 1 is pump loop reponse system figure.
In figure：(1) pressure boundary, (2) pipeline, (3) control valve, (4) pump, (5) control valve, (6) control valve, (7) pressure
