Abstract

The invention relates to a novel directional synchronous water pump, which can change assembling relation between a impeller and a stator by changing a driving force transmission structure between the impeller and a motor shaft, make the impeller smoothly move, minimize generated impact, reduce noise, prevent fitting from damaging, increase life, change uncontrollable rotation direction of the synchronous motor to controllable rotation direction, change nondirectional impeller to directional impeller, and greatly increase draining efficiency of water pump.

Description

technical field [0001] The present invention relates to pumps, in particular pumps on household appliances and the like. More specifically, the present invention relates to a centrifugal pump of this type, which improves the starting reliability of the water pump by increasing the starting angle of the motor; reduces the impact force and increases the use of the water pump by changing the impact direction and speed of the motor shaft on the impeller Longer service life; the directional rotation of the water pump is realized through the one-way braking structure, and the purpose of using the one-way impeller to improve the efficiency of the water pump is achieved. Background technique [0002] figure 1 The operating characteristic curve of a synchronous motor is shown. [0003] figure 2 It shows the start-up structure in which the motor shaft drives the impeller commonly used in current synchronous water pumps. [0004] According to the performance characteristic curve o...
