Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment's technological scheme, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of hydraulic self-balancing power plant described in the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides hydraulic self-balancing power plant, as shown in Figure 1, comprise water pump 1, controller 2, final controlling element 3, low voltage terminal pressure transducer 4 and high voltage terminal pressure transducer 5, the head piece that enters of water pump 1 is provided with low voltage terminal pressure transducer 4, the head piece that goes out of water pump 1 is provided with high voltage terminal pressure transducer 5, the first end of water pump 1 is connected with the first port of final controlling element 3, the second port of final controlling element 3 is connected with the 3rd port of controller 2, the first end of controller 2 is connected with low voltage terminal pressure transducer 4, the second end of controller 2 is connected with high voltage terminal pressure transducer 5.
As optionally, the 4th port of described controller 2 is connected with external control signal, and the optional model of controller 2 is HAKK mono-808/900PID.Described final controlling element 3 is intelligent frequency convertor, and optional model is 2SA8041-GDA00-0002.
Hydraulic self-balancing power plant mesohigh end pressure sensor 5, low voltage terminal pressure transducer 4 that the utility model mode of execution provides are connected with controller 2 by signaling line respectively with final controlling element 3, and final controlling element 3 is connected with water pump l by cable.Controller 2 is known the pressure reduction at water pump two ends by low voltage terminal pressure transducer 4 and high voltage terminal pressure transducer 5, final controlling element 3 is controlled the flow of water pump l by flow, lift and the frequency of adjusting analog amount water pump according to dynamic differential pressure.External control signal can directly be controlled by controller 2 operation of water pump l, and water pump l is operated near efficient power-saving point.Change the rotating speed that automatically regulates operation water pump number of units and each water pump according to user's water consumption, make exit of pump pressure keep constant.When the required flow of user is less than an exit of pump flow be, system changes and has a pump variable frequency speed governing operation according to water consumption, in the time that water consumption increases, pipe-line system internal pressure declines, and at this moment pressure transducer sends controller to the signal detecting, moves judgement by controller, issue instructions to final controlling element, control pump motor by final controlling element, make faster rotational speed constant to ensure system pressure, otherwise in the time that water consumption reduces, pump rotary speed is slowed down, to keep constant voltage.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model embodiment disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
