Abstract
The utility model relates to an energy-saving control device of an electric centrifugal pump. The energy-saving control device comprises a low-power electric centrifugal pump, a high-power electric centrifugal pump and a control circuit and is characterized in that the liquid lines of the low-power electric centrifugal pump and the high-power electric centrifugal pump are connected with each other in series on an external-delivering liquid main line; in the control circuit, the power switch of the low-power electric centrifugal pump connected between the power supply and the low-power electric centrifugal pump in series, and the power switch of high-power electric centrifugal pump connected between the power supply and the high-power electric centrifugal pump in series. The energy-saving control device has the advantages of simple structure, convenient installation and use and low cost; in addition, when the device is used in production process, the electrical energy can be saved greatly, and the production cost is lowered.
Description
Technical field
The utility model relates to energy-saving and cost-reducing technical field, relates to a kind of electric centrifugal pump energy-saving control device specifically.
Background technique
In continuous chemical process, when using electric centrifugal pump to send liquid outside, be usually designed in parallel use of electric centrifugal pump of two equal-wattages, a running, another is standby.Because the influence of each side factor, the flow of sending liquid outside can change, and when flow diminished, the power consumption of electric centrifugal pump can not change, and this has also just wasted electric energy accordingly.Along with development of science and technology, the motor frequency change technology has appearred on the market, saving power has been played certain effect, but motor frequency change technical sophistication, expense are higher, are unfavorable for saving cost of production.
The model utility content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of simple in structure, easy to use and electric centrifugal pump energy-saving control device that expense is cheap is provided.
Its technological scheme is: comprise the electronic centrifugal pump of small-power, high-power electric centrifugal pump and control circuit, it is characterized in that: the liquid line of electronic centrifugal pump of small-power and high-power electric centrifugal pump is connected in parallel on the main line of sending liquid outside; Described control circuit is to be in series with the electronic centrifugal pump power switch of small-power between power supply and the electronic centrifugal pump of small-power, is in series with high-power electric centrifugal pump power switch between power supply and high-power electric centrifugal pump.
Described control circuit can be an ac contactor control circuit.
The utlity model has advantage simple in structure, easy to install, with low cost, use in process of production, greatly saving power, reduce production costs.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Elaborate by embodiment below in conjunction with Figure of description:
As shown in drawings, comprise the electronic centrifugal pump D1 of small-power, high-power electric centrifugal pump D2 and control circuit, it is characterized in that: the liquid line of electronic centrifugal pump D1 of small-power and high-power electric centrifugal pump D2 is connected in parallel on the main line of sending liquid outside; Described control circuit is to be in series with the electronic centrifugal pump power switch of small-power K1 between power supply U and the electronic centrifugal pump D1 of small-power, is in series with high-power electric centrifugal pump power switch K2 between power supply U and high-power electric centrifugal pump D2.Control circuit can also be an ac contactor control circuit.When using the utility model, at first close small-power electronic centrifugal pump power switch K1 and high-power electric centrifugal pump power switch K2, connect power supply U, in the time of need sending liquid outside, the high-power electric centrifugal pump power switch K2 that closes earlier starts powerful electric centrifugal pump D2 and outwards carries liquid; When flow diminishes, at first close high-power electric centrifugal pump power switch K2, powerful electric centrifugal pump D2 is quit work, the electronic centrifugal pump power switch of the small-power of closing earlier again K1, start low power electric centrifugal pump D1 and outwards carry liquid, to reduce power consumption; When flow becomes big again, at first close the electronic centrifugal pump power switch of small-power K1, low power electric centrifugal pump D1 is quit work, high-power electric centrifugal pump power switch K2 again closes, start powerful electric centrifugal pump D2 and outwards carry liquid, the purpose of so reach saving power repeatedly, saving cost of production.
Claims (2)
