Abstract
The utility model relates to a water pump capable of regulating flow. A brushless direct current motor is arranged inside the water pump capable of regulating the flow, and an alternating current-direct current power converter is connected on the outer side of the water pump capable of regulating the flow. The water pump capable of regulating the flow is further provided with a current regulating controller. The water pump capable of regulating the flow has the advantages that an existing asynchronous motor of the water pump is changed into the brushless direct current motor, a direct current is used for providing electric energy of the water pump, the alternating current-direct current power converter is utilized, an alternating current in a power grid is converted into the direct current which are provided for the brushless direct current motor of a water pump main body and used by the brushless direct current motor of the water pump main body, the controller is additionally arranged between the power converter and the water pump main body, passed direct currents of the controller is regulated so as to achieve control the purpose that voltages or current intensity of the direct current input into the water pump are regulated, and thus rotating speeds of the water pump are regulated, and then flowing speeds or lift of water currents of a water outlet of the water pump can be controlled and regulated.
Description
Technical field
The utility model relates to a kind of water pump of adjustable amount.
Background technique
The water pump of using in the industries such as the Shui nationality, gardens gardening and aquatic products in the prior art mainly is the rotation of the magnetic axis (rotor) that utilizes asynchronous motor, drives its waterleaf rotation and even stirs current, reaches the kinetic energy of the fluid that changes its effect and the purpose of potential energy.This kind asynchronous motor need be imported threephase AC, and the needs according to using arrange the magnetic pole of the stator of motor and the rotating speed of rotor, finishes in case set, and under the constant situation of rotor speed, the flow velocity of the water outlet of water pump or lift also are constant; In addition, utilize the water pump of asynchronous motor, can only utilize the Ac of electrical network, reach specified rotating speed after, cannot adjust speed and the lift of the current of pump outlet, be unfavorable for the control of exporting.
The model utility content
The purpose of this utility model is to provide a kind of use direct current and adjustable speed, the isoparametric water pump of lift.
The utility model is achieved through the following technical solutions:
The water pump of described adjustable amount is built-in with dc brushless motor, is circumscribed with AC-DC converter.
Further, the water pump of described adjustable amount also is provided with a current regulation control device.
The beneficial effects of the utility model are: the first, change the existing main body asynchronous motor of water pump into DC Brushless Motor, use direct current that the water pump electric energy is provided.The second, utilize AC-DC converter, with in the electrical network Ac transfer direct current that water pump main body dc brushless motor uses to for its use.Three, between power supply changeover device and water pump main body, add controller, the direct current size of passing through by adjusting color controls, reach the galvanic voltage of adjusting input water pump or the purpose of electric current [strength, thereby regulate the rotating speed of water pump, and then flow velocity or the lift of water outlet current that can the regulating and controlling water pump.
Description of drawings
Fig. 1 is the utility model preferred embodiment schematic representation.
Reference character: 1, the pump housing; 2, water intake; 3, water outlet; 4, controller; 5, AC-DC converter.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described further:
The water pump of described adjustable amount is built-in with dc brushless motor, is circumscribed with AC-DC converter 5.
Preferably, the water pump of described adjustable amount also is provided with a current regulation control device.
In the present embodiment, after water pump is introduced current from water intake 2 usually, can drive the waterleaf rotation by rotor, thereby be reached for the purpose that current provide power, reach corresponding flow velocity when making current from water outlet 3 ejections.When running, Ac at first transfers direct current to by AC-DC converter, regulates size with the power of control water pump by controller 4 then, and then influences performance parameters such as flow velocity and lift, and both convenient the use also was convenient to control output.
Claims (2)
1. the water pump of an adjustable amount, it is characterized in that: the water pump of described adjustable amount is built-in with dc brushless motor, is circumscribed with AC-DC converter.
2. according to the water pump of the described adjustable amount of claim 1, it is characterized in that: the water pump of described adjustable amount also is provided with a current regulation control device.
