Miniature residue-free food-grade brushless direct-current pump

Abstract

The invention discloses a miniature residue-free food-grade brushless direct-current pump. The miniature residue-free food-grade brushless direct-current pump has the advantages that efficiency of the pump is improved by 20% by the aid of the brushless direct-current characteristic, and cleaning can be completed without mounting and demounting an internal structure of a chamber; since pumped liquid outflows from the center of a motor, generated temperature rise during running of the motor can be decreased, and service life is prolonged; addition of any lubricating grease is unneeded, and a bearing structure of the pump is free of any grease lubricant, so that potential safety hazards of food are avoided; a mixing pump structural design combining axial flow with centrifugation achieves efficient heat dissipation effect; by the aid of a motor and rotor isolating and shielding structure, natural lubricating effect is achieved without adding lubricating grease when the pump works, the pump chamber is clean and environment-friendly, and the requirement on the food-grade standard is met; and since water channels of a water inlet and a water outlet are designed to be 'L'-shaped, flowing channels inside the pump can be cleaned by pumping clear water, residual tiny lipid species are avoided, and cleaning is achieved conveniently and quickly.

Description

technical field [0001] The invention relates to the design technology of a food-grade water pump, in particular to a miniature non-residue food-grade brushless DC water pump. Background technique [0002] At present, many liquid foods, including fruit juice and edible oil, need to be poured into the packaging bottle during the packaging process. After the traditional water pump pumps water or juice, there will be residues that are not easy to clean. Indirectly extracting and encapsulating liquids such as the remaining fruit juice remaining last time into the packaging body will cause contamination to the food and affect the hygienic quality of the food. The heat dissipation performance of the traditional water pump is not good, which affects the service life of the water pump itself. It is necessary to add extra lubricating grease to ensure the normal use of the water pump. If you want to clean it thoroughly, you need complicated disassembly and reassembly to achieve it, and...

The heat dissipation performance of the traditional water pump is not good, which affects the service life of the water pump itself. It is necessary to add extra lubricating grease to ensure the normal use of the water pump. If you want to clean it thoroughly, you need complicated disassembly and reassembly to achieve it, and the extra lubricating grease is not enough. food safety hazard
