Fig. 2 is vertical dynamic levitated pump overall schematic.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with drawings and Examples.
The utility model discloses a kind of vertical dynamic levitated pump, comprise the structure and the annexation that describe above-mentioned all parts below pump shaft 1 and water inlet member 2 in detail.
As shown in Figure 1, the overall flare shape of water inlet member 2, it comprises the pump housing 3, pump housing guide bearing 4, suction bell 5, impeller 6, pump cover 7.The pump housing 3 top has the fluid pipeline stretched upwards, and its underpart is hollow body, and the top of the pump housing 3 is connected with bottom.Suction bell 5 is water intake, and it is positioned at the pump housing 3 lower central.Pump housing guide bearing 4 is hollow cylinder, is placed in the center of suction bell 5, upwards extends and connects pump shaft 1.Pump shaft 1 is positioned at the pump housing 3 center for cylindrical body, and wholely runs through the pump housing 3.Impeller 6 connects suction bell 5, and its structure is the rotation blade of hollow, and the center of impeller 6 is connected with pump housing guide bearing 4, impeller 6 with pump housing guide bearing 4 for the center of circle rotate.In the middle of impeller 6 and the pump housing 3, casing ring 11 is installed.
Continue to see Fig. 1, in the below of impeller 6, impeller nut 8 is housed, and above pump cover 7, pump cover guide bearing 9 is housed.Impeller nut 8 connects the center of impeller 6 from below, and pump cover guide bearing 9 connects impeller nut 8 from below.The similar taper of pump cover 7, is placed in the bottom of the pump housing 3, and the center of pump cover 7 is outwardly, and projection is hollow structure, arranges pump cover guide bearing 9 in projection, and the end of projection is water outlet, and water outlet is airtight by plug screw 10, by airtight bottom the pump housing 3.The top of the pump housing 3 is connected with pump housing guide bearing 9 in addition, arranges axle sleeve 12 between the pump housing 3 and pump housing guide bearing 9.
