Semi-open water pump with optimized impeller structure and using method thereof

Abstract

The invention discloses a semi-open water pump with an optimized impeller structure and a using method thereof. The semi-open water pump comprises a pump body containing a motor, a front end cover, and an impeller driven by a motor shaft; the front end cover is fixedly connected with the pump body through screws or buckles in a matched mode; the center position of the front end cover is provided with a shaft hole for allowing a motor rotation shaft to stretch out; the motor rotation shaft is inserted in the shaft hole, and the section, penetrating through the shaft hole, of the motor rotationshaft is fixedly connected with the impeller; and the upper end surface of the front end cover is uniformly provided with a plurality of struts in the circumferential direction. The semi-open water pump can be conveniently installed and connected with pump equipment and is convenient to clean and maintain, the lower surface of the impeller directly forms a water pump water inlet, an anti-leakage flow guide ring and combined blades do not rotate relatively, accordingly, leakage is avoided, and the service life of the water pump is prolonged; and in addition, the impeller is divided into an upper section and a lower section, the proportion of the upper section to the lower section is adopted according to the blades, the water feeding area is large, negative pressure is easy to form, water discharge is stable, the waterpower efficiency is high, and the water pumping efficiency of the water pump is remarkably improved.

Description

technical field [0001] The invention relates to a pump, in particular to a semi-open water pump with an optimized impeller structure for washing and a use method thereof. Background technique [0002] The dishwashers currently on the market mainly drive the spray arm to rotate through the water flow, and spray the water flow through the spray hole to rinse the tableware during the rotation process. The water pump that provides the flow of water is the main component of the dishwasher. [0003] In order to make the water pump easy to install, the impeller can draw water at a lower water level, and a kind of open water pump has appeared at present. For example, the Chinese invention model with publication number CN104235061A and title of invention "A kind of open water pump" discloses the following technical features: the water pump includes a lower casing, a pump body containing a motor and an impeller driven by the motor. The water inlet is located at the bottom and side o...

For example, the publication number is CN207513917U, and the Chinese utility model titled "An Open Water Pump with Improved Impeller Structure and Equipment Using the Open Water Pump" discloses a tubeless pump in order to ensure that the impeller does not release pressure and ensure good concentricity. The impeller with guide ring structure is adopted, but due to the same number of upper and lower blades, the water inlet area is not enough and the water supply is insufficient, resulting in large and small water outlets
