Working method come prevent water pump damage problem, some enterprise's negligences of management, take for a long time operation same water pump operation, cause it
Remaining water pump maintenance is greatly increased.
A kind of constant flow water pump depth energy-saving control system for being capable of depth energy-conservation becomes demand.
Utility model content
The purpose of this utility model is, in view of the above-mentioned problems, providing a kind of constant flow water pump depth energy-saving control system.
The technical scheme that the utility model is used to achieve the above object for：
A kind of constant flow water pump depth energy-saving control system, it includes several frequency converters, quantity identical with the frequency converter
Water pump, flowmeter and controller, the frequency converter, water pump connection, the water pump is connected with pond or circulation pipe network, the water pump
It is connected with the flowmeter, the flowmeter, frequency converter are connected with the controller.
The frequency converter, water pump are two, and the motor of the water pump is electrically connected with the frequency converter.
The water pump is connected by pipeline with the flowmeter, and the flowmeter is electrically connected with the controller.
The beneficial effects of the utility model are：The utility model is simple and reasonable, ingenious in design, can by manually or
Automatic to utilize the multiple water pump operations of transducer drive, low speed runs multiple water pumps simultaneously for selection as needed, reaches that depth is saved
Purpose, the power consumption of pump motor significantly declines, and the effectively save energy reduces cost.
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
Brief description of the drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Embodiment：As shown in figure 1, a kind of constant flow water pump depth energy-saving control system of the utility model, it includes some
Individual frequency converter 1, water pump 2, flowmeter 3 and controller 4 with the identical quantity of frequency converter 1, the frequency converter 1, water pump 2 are connected,
The water pump 2 is connected with pond or circulation pipe network 5, and the water pump 2 is connected with the flowmeter 3, the flowmeter 3, frequency converter 1 and institute
Controller 4 is stated to connect.
The frequency converter 1, water pump 2 are two, and the motor of the water pump 2 is electrically connected with the frequency converter 1.
The water pump 2 is connected by pipeline with the flowmeter 3, and the flowmeter 3 is electrically connected with the controller 4.
In the present embodiment, the motor of water pump is AC induction motor, and the rotating speed and supply frequency of the motor are similar to just
Than the rotating speed of motor can be changed by changing frequency, while also changing flow.Pump-type load belongs to asquare torque load, that is, turns
Square T and rotating speed n2It is directly proportional, the power output W on motor shaft and rotating speed n3It is directly proportional.And the approximate same motor shaft of the power consumption of motor
On power output be directly proportional, i.e., the power consumption of motor is approximately directly proportional to the cube of rotating speed.As can be seen here, turning when motor
When speed is slightly decreased, the power consumption of motor will significantly decline.
For example：Two, the existing industrial cycle backwater water pump of certain enterprise, motor is 30KW, and the method for operation is operation one, standby
With one.Assuming that backwater amount is larger, water pump must full speed capacity operation.Now drive all two water simultaneously using frequency converter
Pump motor is run, and the running frequency of every pump motor is 25HZ, both can be on the premise of flow was not changed.Realize water pump system
The depth energy-saving run of system.
Traditional the working way of pump：Run quantity 1；Rated power 30KW；Actual motion general power 30KW；Rotating speed
100% rated speed；Running frequency 50HZ.
Water pump depth Energy Saving Method：Run quantity 2；2 × 30KW of rated power；Each 50% specified turn of every rotating speed
Speed；Every running frequency 25%；Actual motion general power is：2 × P2=7.5KW；P2 is separate unit pump motor actual motion work(
Rate.
The utility model is simple and reasonable, ingenious in design, manually or automatically can be driven using frequency converter 1 multiple
Water pump 2 is run, and low speed runs multiple water pumps 2 simultaneously for selection as needed, reaches the purpose of depth energy-conservation, the consumption of the motor of water pump 2
Electricity significantly declines, the effectively save energy, reduces cost.
It is described above, only it is preferred embodiment of the present utility model, not makees any formal to the utility model
Limitation.Any those skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and techniques content of the disclosure above makes many possible variations and modification to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore every content without departing from technical solutions of the utility model, the shape according to the utility model
The equivalence changes that shape, construction and principle are made, all should be covered by protection domain of the present utility model.
