Embodiment
Accompanying drawing below in conjunction with embodiment is elaborated to embodiment of the present utility model.
Referring to Fig. 1, Fig. 1 is the structural representation of core-pulling mechanism vertical water pump of the present utility model.
As shown in the figure, core-pulling mechanism vertical water pump of the present utility model comprises outer cylinder body 1 and the inner core rotatable parts 2 that are arranged in the outer cylinder body 1.
Described outer cylinder body 1 is by taking over 11, being arranged on to take over the Discharging bent-tube 12 on 11 and be installed in water inlet loudspeaker 13 and the base plate 14 of taking over 11 1 ends and forming.
Described rotatable parts 2 comprise pump shaft 21, support the bearing 22 of pump shaft 21, bearing chamber 214 outside the bearing 22, the coupling 215 that is connected with pump shaft 21, the impeller 23 that is connected with pump shaft 21 1 ends, the motor (not shown) that is connected with pump shaft 21 the other ends has pump cover 25 on the pump shaft 21 above the corresponding Discharging bent-tube 12, the outside of impeller 23 has blade wheel chamber 26 and diffuser 27, is with inner connecting tube 28 on the pump shaft 21.
What the pump shaft 21 in above-mentioned rotatable parts 2, bearing 22, bearing chamber 214, coupling 215, impeller 23, blade wheel chamber 26, diffuser 27, inner connecting tube 28 compositions were not fixedlyed connected with outer cylinder body 1 can be from the core-pulling mechanism of extraction in the outer cylinder body 1.
Fix several supportings on the described outer cylinder body 1, described core-pulling mechanism is supported in several supportings.Present embodiment has with lower linking tube 29 places at diffuser 27 and is fixed by bolts to the supporting of first on the outer cylinder body 1 (not shown), has at pump cover 25 and base plate 14 places to be fixed by bolts to the supporting of second on the outer cylinder body 1 (not shown).Core-pulling mechanism is supported in two supportings.This core-pulling mechanism can be extracted out from pump outer cylinder body 1 during maintenance, and wherein pump shaft 21, coupling 215 and impeller 23 etc. are formed rotor part.
