The beneficial effect of the utility model: it results in pipe network pressure to reduce to break down when a water pump, and second platform water pump can drop into voluntarily and supply water, guarantees that pipe network pressure maintains the within range of requirement, and all parameters of operation include pressure, select reserve pump etc. All can pass through the touch -sensitive screen setting, its characteristics be use one reliable and stable fully, frequency conversion energy -conservation, can use has the system of requirement any to pressure or liquid level.
Description
Technical field
This utility model relates to water system, particularly relates to a kind of standby handover control system that supplies water.
Background technology
Generally plant water supply water pump the using and the reserved, are only that second water pump just can come into operation when a water pump breaks down, and ductwork pressure are not adjusted, ductwork pressure can be caused to decline suddenly, and impact produces.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of standby handover control system that supplies water, to solve deficiency of the prior art.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions:
A kind of standby handover control system that supplies water, wherein, including controlling system cabinet, pressure transducer and two-way for water passage, include the strainer valve, water pump and the check valve that are sequentially connected with respectively for water passage described in two-way, described water pump is all with variable frequency drives, the described outfan for water passage connects described pressure transducer, and described control system cabinet connects described water pump and the described outfan for water passage respectively；Being provided with interconnective man machine interface and PLC master controller in described control system cabinet, described PLC master controller connects the variable frequency drives of described water pump and described pressure transducer respectively.
The standby handover control system of above-mentioned water supply, wherein, described man machine interface is touch screen.
Compared with the prior art, the beneficial effects of the utility model are in that:
PLC is adopted to control two variable frequency pumps and regulate frequency converter frequency, reach to control water supply network pressure, when a water pump breaks down or other problems causes that ductwork pressure reduces, second water pump can automatically engage water supply, it is ensured that ductwork pressure maintains in the scope of requirement, the all parameters run include pressure, select reserve pump etc., all can be arranged by touch screen, be characterized in that the using and the reserved are reliable and stable, energy-saving and frequency-variable, it is possible to be applied in any system that pressure or liquid level are required.
Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 illustrates the pipeline artwork of this utility model standby handover control system of water supply；
Fig. 2 illustrates the control principle drawing of this utility model standby handover control system of water supply.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this 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 obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
It should be noted that when not conflicting, the embodiment in this utility model and the feature in embodiment can be mutually combined.
With reference to shown in Fig. 1, Fig. 2, this utility model standby handover control system of water supply includes controlling system cabinet 0, pressure transducer 2 and two-way for water passage, two-way includes the strainer valve 3, water pump 1 and the check valve 4 that are sequentially connected with respectively for water passage, water pump 1 is all with variable frequency drives 5, for the outfan Bonding pressure sensor 2 of water passage, control system cabinet 0 and connect water pump 1 and the outfan for water passage respectively.Control system cabinet 0 is provided with interconnective man machine interface 6 and PLC master controller 7, PLC master controller 7 connects variable frequency drives 5 and the pressure transducer 2 of water pump 1 respectively.
In preferred embodiment of the present utility model, man machine interface 6 is touch screen.This handover control system can freely define main pump, the working life of two water pumps of balance, when there being any reason to cause that goal pressure is on the low side, can automatically engage reserve pump, it is to avoid pressure big ups and downs impact produces.Supporting on-line real time monitoring pressure curve, record Long-term change trend, supporting that technique achieves, when machine occurs delaying in a water pump, another water pump can work independently, and supports on-line maintenance simultaneously.
From the above it can be seen that advantage of the present utility model is in that:
PLC is adopted to control two variable frequency pumps and regulate frequency converter frequency, reach to control water supply network pressure, when a water pump breaks down or other problems causes that ductwork pressure reduces, second water pump can automatically engage water supply, it is ensured that ductwork pressure maintains in the scope of requirement, the all parameters run include pressure, select reserve pump etc., arrange such as through touch screen, be characterized in that the using and the reserved are reliable and stable, energy-saving and frequency-variable, it is possible to be applied in any system that pressure or liquid level are required.
Above specific embodiment of the utility model being described in detail, but this utility model is not restricted to particular embodiments described above, it is intended only as example.To those skilled in the art, any equivalent modifications and replacement are also all among category of the present utility model.Therefore, impartial conversion done under without departing from spirit and scope of the present utility model and amendment, all should be encompassed in scope of the present utility model.
