Definitions
- the invention relates to a water pump with adjustable flow.
- the water pump used in the aquarium, gardening, horticulture and aquatic industries mainly uses the rotation of the magnetic shaft (rotor) of the asynchronous motor, and the movement of the water blade to rotate or even agitate the water flow to achieve the kinetic energy of the fluid that changes its function.
- the asynchronous motor needs to input three-phase alternating current, and according to the needs of the application, set the stator magnetic pole and the rotor speed of the motor. Once the setting is completed and the rotor speed is constant, the flow rate or head of the water outlet of the water pump is also constant; Pumps using asynchronous motors can only use the AC power of the grid. After reaching the rated speed, the speed and head of the water flow at the pump outlet cannot be adjusted, which is not conducive to the output control.
- An object of the present invention is to provide a water pump that uses direct current and that can adjust parameters such as flow rate and head.
- the adjustable flow water pump has a DC brushless motor built therein, and an AC/DC power converter is externally connected.
- the adjustable flow rate water pump is further provided with a current regulation controller.
- the beneficial effects of the invention are as follows: First, the existing main body asynchronous motor of the water pump is changed For DC brushless motors, DC power is used to supply pump power. Second, the AC power in the power grid is converted into the DC power used by the DC brushless motor of the water pump body for use by the AC/DC power converter. Thirdly, between the power converter and the main body of the pump, a controller is added to adjust the voltage or current intensity of the direct current of the input water pump by adjusting the magnitude of the direct current passed by the controller, thereby adjusting the rotational speed of the water pump, and then controlling Adjust the flow rate or head of the water outlet of the pump.
- Figure 1 is a schematic view of a preferred embodiment of the present invention.
- the water pump with adjustable flow rate has a DC brushless motor built therein, and an AC/DC power converter 5 is externally connected.
- the adjustable flow pump is further provided with a current regulation controller.
- the water blade is rotated by the rotor to achieve the purpose of powering the water flow, so that the water flow reaches the corresponding flow rate when it is ejected from the water outlet 3.
- the AC power is first converted to DC by the AC/DC power converter, and then the controller 4 is adjusted to control the power of the pump, thereby affecting the performance parameters such as the flow rate and the head, which is convenient for use and easy to control the output.

Abstract
La présente invention concerne une pompe à eau à débit variable ayant un moteur sans balai à CC disposé à l'intérieur et connecté à l'extérieur avec un convertisseur d'alimentation en courant CA-CC (5) et pourvu d'un système de commande de réglage de courant (4). La pompe à eau peut convertir le courant alternatif CA du réseau électrique en courant continu CC utilisé par le moteur sans balai à CC de la pompe à eau et régler la vitesse de rotation de la pompe à eau et ainsi le débit de la pompe à eau en réglant la valeur du courant DC circulant à travers le système de commande.
