Preferably, described front cover is also provided with a bearing chamber, a drip chamber and a gutter; Described bearing chamber is positioned at the end corresponding to described motor cavity of front cover; Described drip chamber between described closed chamber and bearing chamber, and described rotating shaft is arranged with a rubber thrower corresponding to this drip chamber place; The top in described gutter is communicated with drip chamber, and lower end part is on the outer side wall of front cover.
The beneficial effects of the utility model are: both pump housing support and motor front end cover are become one, and machine volume is diminished, and change the wind-cooling heat dissipating of conventional motors, and change water-cooling into, radiating effect strengthens greatly.
Accompanying drawing explanation
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the sectional elevation (broken section) of existing electric pump.
Fig. 2 is the sectional elevation of a kind of electric pump of the present invention.
Fig. 3 is the sectional elevation of front cover in the present invention.
Embodiment
Refer to Fig. 2, a kind of small volume electric pump 100, comprise the pump housing 1 and motor 2; The described pump housing 1 comprises front pump cover 11 and impeller 12; Described motor 2 comprises rear end cover 21, electric motor units 22, rotating shaft 23 and front cover 24; Described electric motor units 22 comprises rotor 221 and stator 222.
Referring again to Fig. 2, described front cover 24 encloses a cavity M with described front pump cover 11, and described impeller 12 is contained in the front portion of this cavity M; Described rear end cover 21 surrounds a motor cavity N with front cover 24, and described rear end cover 21 and front cover 24 lock pair are connected, and described electric motor units 22 is placed in this motor cavity N; Described rotating shaft 23 is successively through electric motor units 22, front cover 24 and impeller 12, and described rear end cover 21 is fixed in rotating shaft 23, and this rotating shaft 23 can rotate setting relative to rear end cover 21.
Refer to Fig. 2 and Fig. 3, one end place of the contiguous described cavity M of described front cover 24 is provided with a closed chamber 241, is arranged with a seal ring 3 in sealing room 241.Described seal ring 3 is sheathed in rotating shaft 23, and seals described cavity M.Described front cover 24 corresponds to described cavity M place and be provided with a cooling ditch 242, increase in pump is that cavity M inner fluid 4 fixes the area of contact at inner stator 222 position with front cover 24, the heat that when motor 2 works, iron core produces, is taken away by the fluid 4 of pump internal circulation flow, reaches the object of cooling.
Referring again to Fig. 2 and Fig. 3, described front cover 24 is also provided with bearing chamber 243, drip chamber 244 and a gutter 245; Described bearing chamber 243 is positioned at the end corresponding to described motor cavity N of front cover 24; Described drip chamber 244 between described closed chamber 241 and bearing chamber 243, and described rotating shaft 23 is arranged with a rubber thrower 5 corresponding to this drip chamber 244 place; The top in described gutter 245 is communicated with drip chamber 244, and underpart 245a is positioned on the outer side wall of front cover 24.Electric pump 100 Long-Time Service can cause seal ring 3 to wear and tear, slight leakage phenomenon may be there is, inner for preventing leak fluid 4 from entering motor 2 along rotating shaft 23, a drip chamber 244 is provided with between closed chamber 241 and bearing chamber 243, and a rubber thrower 5 has been installed in rotating shaft 23, when revealing fault and occurring, fluid 4 is blocked by rubber thrower 5 and throws away, and finally by gutter 245, the fluid 4 of leakage is discharged motor 2.
Referring again to Fig. 2, when applying the present invention and working, rotating shaft 23 drives described impeller 12 to rotate, fluid 4 sucks from the water intake 13 of the pump housing 1, accelerate to obtain energy through impeller 12 to throw away from the water outlet 14 of the pump housing 1, in the process, the fluid 4 of high-speed circulating flowing is filled with in the cavity M that the pump housing 1 and front cover 24 surround, also the fluid 4 of flowing is filled with in cooling ditch 242, the fluid 4 that the heat produced when now motor 2 works will be transmitted in cooling ditch 242, take out of outside pump by the fluid 4 circulated, reach cooling object.
Traditional electric pump 100' support and front cover 24' are two independently parts, and both become one by the present invention, and machine volume is diminished, and change the wind-cooling heat dissipating of conventional motors 2', and change water-cooling into, radiating effect strengthens greatly.
