Abstract

The invention discloses a condensate prevention type circulating pump. The condensate prevention type circulating pump comprises a motor, a pump shell and an impeller, the impeller is arranged in thepump shell, a rotor of the motor is connected with the impeller, the motor comprises a direct-current three-phase stator coil and the rotor, the direct-current three-phase stator coil and a temperature sensor are plastically packaged in the same injection molding body, the temperature sensor is used for detecting the temperature of the direct-current three-phase stator coil, an electromagnetic driving cavity is formed in the injection molding body, and the rotor is arranged in the electromagnetic driving cavity. According to the condensate prevention type circulating pump, as the direct-current three-phase stator coil is plastically packaged in the injection molding body, the insulation effect is quite good, the problem that the stator coil of the motor is short-circuited due to condensedwater is effectively solved; particularly, the stator coil and the temperature sensor are plastically packaged in the same injection molding body, so that accurately detecting the temperature of the plastically packaged stator coil is carried out; and moreover, the condensate prevention type circulating pump has the characteristics that the installation is convenient, the insulativity is good, leading-out wires are orderly arranged along a wiring groove, the structure is compact and the heat dissipation is good.

Description

technical field [0001] The invention relates to a water pump, in particular to a circulation pump. Background technique [0002] In the prior art, the stator of the motor in the circulation pump is plastic-sealed, and the existing problems are: first, the temperature of the stator cannot be accurately detected; second, the heat dissipation of the motor is not good; third, the insulating sleeve of the stator is inconvenient Installation, because it is not completely covered, so the insulation is poor; 4. The existing waterproof power connector is fixed by a nut. Due to the limited space on the shell, there is a defect of inconvenient installation; 5. The coil leads are easy to contact each other or There is a crossover defect. [0003] For example, a patent document with a publication number of 207195210U was published on April 6, 2018. The present invention relates to a shielded circulating pump, which solves the problems in the prior art that the shielding sleeve is a spli...
