The type of electric-motor pump can have a variety of, such as gas pump, such as the air pump used in hair-dryer.For another example liquid
The washing pump used in pump, such as dish-washing machine.The concrete structure of insulating barrier corresponding to different electric-motor pumps can be different.To blow
Exemplified by the air pump used in blower fan, because air will not cause to damage to the stator core in stator module 4.Therefore, insulate
Layer can only be laid in the surface being in contact with stator winding of stator core.In this case, air pump is in pumped air,
The end face of stator core directly will be in contact with pumped medium.Cold air is entered by pumped medium entrance 10, by stator core
Preheating after, by the output of pumped medium outlet 3, then predetermined temperature is heated to by heating tube or heater strip.Due to cold air
Stator core is directly contacted, the heat that stator core distributes can be absorbed, and 3 rows are exported by pumped medium after heat is absorbed
Go out, new cold air enters back into axially spaced-apart cooling stator core.Air namely for cooling stator core is in stream
The relatively low cold air of the temperature of more new state is moved, will not the temperature rise with the increase for absorbing heat.Therefore, have more preferable
Cooling effect.In addition, for need the in the case of of heating, such as need blow out hot blast situation, because cold air passes through electric-motor pump
When be preheated, air can be heated to predetermined temperature so as to need to provide smaller heating power, be advantageous to save energy
Source.
For liquid pump, by taking the washing pump in dish-washing machine as an example, because stator core can not contact with liquid, therefore, need
Will be in for example whole outer surface coated with thermally conductive insulating barriers in the outer surface of stator core.Typically, the insulating barrier can be plastics,
Such as PPSU thermal plastics.A part for thermally conductive insulating layer forms rotor assembly supporting part 12.Pass through the isolation of thermally conductive insulating layer
Effect, stator core, stator winding, rotor 8 and bearing and pump liquid can be kept apart, electric-motor pump use has been effectively ensured
Security.Further, since the conductive force of thermally conductive insulating layer is better than air, heat-transfer effect is good, direct by thermally conductive insulating layer
The radiating effect during pump liquid of contact flow renewal is more preferable, is advantageous to motor radiating, extends the service life of electric-motor pump.
In addition, for the washing pump used in dish-washing machine, the pumped medium outlet 3 of pump case 1 is connected with heating pipe, the cleaning after preheating
Need to consume less heating power with water and can be heated to predetermined temperature, such as 60 degrees Celsius.Therefore, section can be played
The about effect of the energy.
The utility model embodiment provide electric-motor pump may apply to the household electrical appliances such as blower fan, dish-washing machine, automotive electronics pump and
In automobile industry.
