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.

Abstract

一种可调节流量的水泵，内置有直流无刷电机，外接有交直流电源转换器（5），还设有电流调节控制器（4）。这种水泵能够将电网中的交流电转换为水泵中的直流无刷电机使用的直流电，并通过调节通过控制器的直流电大小，调节水泵的转速，进而调节水泵的流量。

Description

可调节流量的水泵
技术领域
本发明涉及一种可调节流量的水泵。
背景技术 说
现有技术中水族、园林园艺及水产等行业中应用的水泵主要是利 用异步电动机的磁轴（转子）的旋转，带书动其水叶旋转乃至搅动水流， 达到改变其作用的流体的动能和势能的目的。此种异步电动机需要输 入三相交流电， 根据应用的需要， 设置电动机的定子磁极及转子的转 速， 一旦设定完成， 转子转速恒定的情况下， 水泵的出水的流速或扬 程也是恒定的； 另外， 利用异步电动机的水泵， 只能利用电网的交流 电，达到额定的转速后，不可以调整水泵出水口的水流的速度和扬程， 不利于输出的控制。
发明内容
本发明的目的在于提供一种使用直流电且可调节流速、扬程等参 数的水泵。
本发明是通过以下技术方案实现的- 所述可调节流量的水泵内置有直流无刷电机，外接有交直流电源 转换器。
进一步地， 所述可调节流量的水泵还设有一电流调节控制器。 本发明的有益效果在于： 第一、将水泵现有的主体异步电动机改 为直流无刷电动机， 使用直流电提供水泵电能。 第二、 利用交直流电 源转换器，将电网中的的交流电转为水泵主体直流无刷电机使用的直 流电供其使用。 第三、 在电源转换器和水泵主体之间， 加上控制器， 通过调节控制器通过的直流电大小，达到调节输入水泵的直流电的电 压或电流强度的目的， 从而调节水泵的转速， 进而可以控制调节水泵 的出水口水流的流速或扬程。
附图说明
图 1为本实用新型优选实施例示意图。
附图标记： 1、 泵体； 2、 进水口； 3、 出水口； 4、 控制器； 5、 交直流电源转换器。
具体实施方式
下面结合附图及具体实施方式对本实用新型做进一步描述： 所述可调节流量的水泵内置有直流无刷电机，外接有交直流电源 转换器 5。
优选地， 所述可调节流量的水泵还设有一电流调节控制器。
在本实施例中， 通常水泵从进水口 2引入水流后， 即可通过转子 带动水叶旋转， 从而达到为水流提供动力的目的， 使得水流从出水口 3喷出时达到相应的流速。 在运作时， 交流电首先通过交直流电源转 换器转为直流电， 然后通过控制器 4调节大小以控制水泵的功率， 进 而影响流速和扬程等性能参数， 既方便使用， 也便于控制输出。
