Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of the pump operation regulator control system of subregion detection.

Specific embodiment

As shown in FIG. 1, FIG. 1 is a kind of pump operation regulator control systems of subregion detection proposed by the present invention.

Referring to Fig.1, the pump operation regulator control system of subregion detection proposed by the present invention, comprising: fluid passage, n pump, n A detection module, n adjustment module, control module;

N pump is successively evenly arranged from the entrance of fluid passage to outlet, and fluid passage is divided into n+1 area by n pump Domain is denoted as A1、A2、A3……An+1

N detection module is respectively used to detection A2、A3、A4……An+1The mean flow rate of liquid, is denoted as V in region1、V2、 V3……Vn

N adjustment module is respectively used to adjust the operating power of n pump, and n adjustment module is corresponded with n pump;

Control module is communicated to connect with n detection module, n adjustment module;

Control module obtains the mean flow rate V of liquid in n region by n detection module1、V2、V3……Vn, and it is right Mean flow rate V1、V2、V3……VnIt is analyzed, and instruction controls n adjustment module movement based on the analysis results.

Specifically:

Preset flow rate range [V is stored in control module11,V22], as the detected value V of j-th of detection modulejBeyond default When flow rates, control module instruction controls j-th and+1 adjustment module movement of jth;

In n adjustment module, each adjustment module is successively equipped with m power gear from as low as big;For each tune It saves module and m power gear is set, can dynamically each operating power pumped be increased and be reduced, pointedly mentioned The function and effect of each high pump;

Control module obtains A by j-th of detection modulej+1The mean flow rate V of liquid in regionj, work as Vj<V11When, show Aj+1The mean flow rate of liquid is relatively low in region, it may be possible to which the effect dynamics of j-th of pump is lower, it is also possible to be jth+1 pump Effect dynamics it is lower, be at this time to improve A to be leftj+1The flow velocity of the liquid in region and A will be enteredj+1The liquid in region Flow velocity, control module instruction controls the supreme level-one power gear of j-th adjustment module movement, j-th of pump of adjustment, jth+1 tune It saves module action and adjusts jth+1 supreme level-one power gear of pump, by increasing the operating power of j-th of pump and jth+1 pump, Make subsequent inflow Aj+1The liquid in region can keep suitable stream under the action of j-th of pump and jth+1 pump after the adjustment Speed, thus by the flow control of unitary fluid in fluid passage in optimum range, while guaranteeing that the effect to each pump is imitated Fruit;

Work as Vj>V22When, show Aj+1The mean flow rate of liquid is higher in region, it is possible to j-th pump effect dynamics compared with It is high, it is also possible to be that jth+1 effect dynamics pumped is higher, be suitable for for what guarantee flowed through the liquid of j-th of pump and jth+1 pump Flow velocity, control module instruction control j-th of j-th of pump of adjustment module movement adjustment to low level-one power gear, jth+1 adjusting Module action adjusts jth+1 pump to low level-one power gear, by reduce the operating power of j-th of pump and jth+1 pump come The energy that j-th of pump and jth+1 pump provide is reduced, prevents the speed for flowing through the liquid of j-th of pump and jth+1 pump further Increase, the mean flow rate of unitary fluid in general warranty fluid passage;

Wherein, 1≤j≤n.

By above-mentioned regulation process, the work of each pump can be judged according to the mean flow rate of liquid in each region Whether power is suitable for and adjusting the operating power of pump in time when being not suitable for, each pump is made to keep suitable working dynamics, from And guarantee the working efficiency of each pump.

In a further embodiment, in n detection module, any one detection module includes multiple detection units, more The installation site of a detection unit is all different;With from different location and different angle to the flow velocity of liquid in each region into Row acquisition and analysis are conducive to improve the comprehensive and specific aim to the mean flow rate detection of liquid in each region;And appoint One detection unit includes at least a flow sensor, further ensures that the mean flow rate detection of liquid in each region Validity.

Fluid passage is divided by the pump operation regulator control system for the subregion detection that present embodiment proposes using multiple pumps Multiple regions, and the mean flow rate of liquid in each region is acquired and is analyzed, by by its mean flow rate and default Flow rates are compared to judge whether flow rate of liquid deviates preset level in the region, and then are obtained according to judging result Whether the operating power of pump corresponding with the region is suitable for finally targetedly being adjusted to the operating power of said pump again, The liquid for making it that good working order be kept to flow through it provides suitable energy, so that it is guaranteed that liquid whole in fluid passage Body keeps suitable flow velocity and kinetic energy, improves this system to the regulation efficiency and regulating effect of unitary fluid.Further, this reality Apply mode and be that each pump is equipped with multiple operation ranges, and according to each pump the mean flow rate of liquid in corresponding region come Judge whether energy that pump provides is suitable for and dynamically increaseing or decreasing according to judging result operating power of each pump, needle The regulating effect to each pump is improved to property, to guarantee the regulation efficiency to liquid in fluid passage.

The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
