Abstract
The utility model relates to an automatic switching device of an energy saving water pump. The automatic switching device comprises a water pump main body and is characterized in that the output end of the water pump is connected with a pressure sensor; the pressure sensor is connected with the input end of a controller; the output end of the controller is connected with a frequency converter; and the frequency converter is connected with the input end of the water pump. The pressure of the water pump is sensed by the pressure sensor in real time, so that the working efficiency of the water pump is controlled and the energy saving effect is achieved; and when the pressure is low or external voltage breaks down, the water pump can be automatically switched to a power frequency state from a variable frequency state to operate, so that the halt of an air compression caused by the water pump is reduced.
Description
Technical field
The utility model relates to a kind of water pump, and particularly a kind of energy-saving water pump automatic switching control equipment belongs to energy-saving field.
Background technique
At present, in using process, often can't monitor the size of output hydraulic pressure in real time, can't adapt to different output hydraulic pressure according to the change that output hydraulic pressure carries out the pump working frequency, thereby cause energy loss water pump.Therefore, how addressing the above problem is research purpose of the present utility model.
Summary of the invention
The purpose of this utility model is to provide a kind of energy-saving water pump automatic switching control equipment, helps reducing the water pump energy consumption, reaches purpose of energy saving.
Of the present utility model being characterised in that: a kind of energy-saving water pump automatic switching control equipment, comprise the water pump main body, it is characterized in that: the output terminal of described water pump is connected with pressure transducer, described pressure transducer is connected with the input end of a controller, the output terminal of described controller is connected with frequency variator, and described frequency variator is connected with the input end of water pump.
Advantage of the present utility model: the utility model is responded to the pressure of water pump in real time by pressure transducer, thus the frequency of okperation of control of pump, to reach energy-conservation effect; When low or external voltage breaks down when pressure, can be transformed into power frequency operation automatically, shut down thereby reduce because of water pump causes air compressor in time from the frequency conversion state.
Description of drawings
Fig. 1 is the utility model embodiment working principle block diagram.
Embodiment
With reference to figure 1, a kind of energy-saving water pump automatic switching control equipment, comprise the water pump main body, the output terminal of described water pump is connected with pressure transducer, described pressure transducer is connected with the input end of a controller, the output terminal of described controller is connected with frequency variator, and described frequency variator is connected with the input end of water pump.
Specific implementation process: the pressure transducer of the hydraulic pressure end of this device by being located at water pump output is monitored in real time and is exported hydraulic pressure, pass to controller according to the signal that pressure transducer sent then, controller is controlled the frequency of okperation of regulating water pump to the frequency variator that is connected with water pump again, thereby regulate the output hydraulic pressure of water pump, finish according to concrete output hydraulic pressure and regulate frequency of okperation, the final energy loss that reduces reaches purpose of energy saving.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
