Described display is provided with Isobarically Control module and thermostatic control module.
Compared with prior art, this utility model embodiment at least has the advantage that
In this utility model embodiment, by monitoring devices such as Frequency Converter Control integrated in a switch board, PLC control and display, and weave control program in advance, the signal of telecommunication according to input terminal input, it is automatically adjusted duty and the operating frequency of each pump, make it possible to directly apply to the team control place of the pump under constant temperature, constant voltage etc. require, be finally reached the effect of constant temperature or constant voltage, saved substantial amounts of debugging cost for user.
Accompanying drawing explanation
The structural representation of the frequency conversion team control cabinet of a kind of pump that Fig. 1 provides for this utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model, the technical scheme in this utility model is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, the frequency conversion team control cabinet of a kind of pump proposed for this utility model embodiment, including converter 1, PLC2 and display 3, it is characterised in that: converter 1, PLC2 and display 3 are connected in same circuit；PLC2 passes through circuit external temperature signal transducer 21 and pressure signal sensor 22, converter 1 is by the external frequency control circuit of circuit 11, the electric power loop of pump connects the frequency conversion lead-out terminal of team control cabinet, pump operation status circuit 4 and pump control loop 5 and connects the input terminal of team control cabinet.
Preferably, PLC2 is provided with pid control module, polling system module and pump frequency on off control module, temperature signal sensor and the pressure signal sensor being sequentially connected with to be connected with pid control module.
Preferably, display 3 is provided with Isobarically Control module and thermostatic control module, arranges at display 3 interface current for constant voltage or thermostatic control during use.
As follows to the use procedure declaration of this equipment below in conjunction with the accompanying drawings:
Temperature signal and the pressure signal of each water pump are sent to PLC by sensor, start and stop pump number and pump frequency are sent to polling system module by pid control module according to temperature signal and pressure signal, the start and stop of concrete pump that pump frequency on off control module exports according to polling system module, frequency setting value, it is automatically adjusted duty and the operating frequency of each pump, thus is finally reached the effect of constant temperature or constant voltage.
Compared with prior art, this utility model embodiment has the advantage that
In this utility model embodiment, by monitoring devices such as Frequency Converter Control integrated in a switch board, PLC control and display, and weave control program in advance, the signal of telecommunication according to input terminal input, it is automatically adjusted duty and the operating frequency of each pump, make it possible to directly apply to the team control place of the pump under constant temperature, constant voltage etc. require, be finally reached the effect of constant temperature or constant voltage, saved substantial amounts of debugging cost for user.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within 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 claims.
