Cross-flow wave making pump

Abstract

This invention relates to a cross-flow wave making pump comprising an impeller shell forming a water intake and a water outlet, an impeller assembly pivotally connected to two ends of the impeller shell, and a motor used for driving the impeller assembly; wherein, the impeller assembly comprises an impeller used for driving a liquid flow, a first turntable and a second turntable respectively fixed at two ends of the impeller, wherein the first turntable is provided with a shaft rotatably mounted in the impeller shell, the second turntable is provided with a cavity used for receiving a rotor shaft of the motor. The embodiments of the present invention can provide a sufficient liquid-circulation in a container, and significantly reduce the dead zone where the liquid flows extremely slowly.

Description

FIELD OF THE INVENTION[0001]This invention relates to a wave making pump, especially to a cross-flow wave making pump that can provide a sufficient liquid-circulation in a container.BACKGROUND OF THE INVENTION[0002]In most cases, existing wave making pumps use inner rotor brushless motor with propeller-type axial vanes to drive a liquid flow, or use inner rotor brushless motor with centrifugal vanes to swallow and extrude liquid so as to force the liquid to flow. The inner rotor brushless motor is characterized by high rotation speed but low torque, so it can only drive small-sized vanes, moreover, the outlet area of this kind of wave making pumps is relatively small, when a high flow velocity is required, it needs to increase the rotation speed to increase the flow rate. Therefore, when this kind of wave making pump is applied to making liquid circulation or making waves, it's likely to cause uneven flow or insufficient liquid-circulation, and form, in the container, dead zones whe...

Benefits of technology

The cross-flow design achieves significant reduction in dead zones with improved liquid circulation and increased flow rates, overcoming the limitations of traditional pumps by providing high torque and efficient liquid circulation.

Problems solved by technology

The inner rotor brushless motor is characterized by high rotation speed but low torque, so it can only drive small-sized vanes, moreover, the outlet area of this kind of wave making pumps is relatively small, when a high flow velocity is required, it needs to increase the rotation speed to increase the flow rate.

Therefore, when this kind of wave making pump is applied to making liquid circulation or making waves, it's likely to cause uneven flow or insufficient liquid-circulation, and form, in the container, dead zones where the liquid flows extremely slowly.
