A heating pump includes a pump body and a driving motor. The pump body includes a pump housing with a water inlet and a water outlet, a heating member fixed in an interior of the pump housing, and an impeller connected with the driving motor. The heating member includes fittings and a heating coiled pipe connected between the fittings and bent into an arc. The impeller is disposed at an upper part of the pump housing, one end of the driving motor is disposed adjacent the impeller, and the heating coiled pipe circles around a radial side portion of part of the driving motor. The heating pump has a rational design and high heat exchange efficiency. The safety auxiliary motor has a low requirement for power. The axial size of the water pump is significantly reduced.

Heating pump

A brushed rotatory device () includes a stator, a rotor (), an impeller (), and a chamber () accommodating the commutator () and brushes () to contain debris from consumed brushes. The impeller causes air flow to dissipate heat generated by the rotatory device and may further carry the consumed brush debris away. The rotatory device includes flow channel(s) () which communicates with the impeller exhaust and accommodates absorbent or filtering materials () to trap the debris in the air flow. The commutation area may be double contained by using flange(s) () or wall(s) () to trap or confine a greater part of the debris in a localized region or to reduce noise from the rotatory device operations.

Brushed rotatory device with collecting structure

A heating pump includes an electric motor, a pump housing fixed to the motor, an impeller driven by the motor, and a ring heater with an inner hole for heating fluid in the pump housing. The pump housing has a pump chamber and a pump inlet and a pump outlet which are in fluid communication with the pump chamber. The impeller is received in the pump housing and having an impeller inlet and a plurality of impeller outlets. The ring heater is disposed inside the pump chamber and between the pump inlet and the impeller. The impeller inlet is in fluid communication with the pump inlet via the inner hole.

A centrifugal pump includes an electric motor, an impeller driven by the motor and a pump housing having an impeller chamber, an inlet in communication with the impeller chamber via an opening, and first and second outlets in communication with the impeller chamber. The impeller chamber has an interference structure which forms first and second flow channels in communication with the first and second outlets. The interference structure directs the fluid in the impeller chamber to flow through the first outlet via the first flow channel when the impeller rotates in a first direction or to flow through the second outlet via the second flow channel when the impeller rotates in the opposite direction.
