Description
Technical field
The utility model relates to a kind of centrifugal pump.
Background technique
Existing centrifugal pump comprises base, the pump housing, impeller and motor, and the described pump housing and motor are located on base, and described motor is provided with main shaft, and described impeller to be arranged in the pump housing and to be connected with one end of main shaft, and described main shaft is provided with mechanical seal device.Existing centrifugal pump has the following disadvantages: one is because the weight of the pump housing is large, mobile very inconvenient; Two is that existing mechanical seal device comprises stationary ring, rotating ring, drive sleeve and spring, the phenomenon of drive sleeve fracture in use often occurs, affects the quality of mechanical seal structure; Three is existing blade wheel structure not science, and lift is little.
Model utility content
The purpose of this utility model is exactly provide a kind of lift large for above-mentioned situation, and mechanical seal quality is good, and is convenient to the centrifugal pump of movement.The purpose of this utility model realizes by following scheme: a kind of centrifugal pump, comprise base, the pump housing, impeller and motor, the described pump housing and motor are located on base, described motor is provided with main shaft, described impeller to be arranged in the pump housing and to be connected with one end of main shaft, described main shaft is provided with mechanical seal device, it is characterized in that described base bottom both sides are provided with movable pulley, is convenient to mobile, described mechanical seal device comprises the rotating ring be arranged on main shaft and the stationary ring be arranged in machine envelope seat, the contact end face that stationary ring and machine seal seat forms primary sealing area, the side end face that described rotating ring contacts with stationary ring arranges depressed part, this depressed part end face corresponding to stationary ring matches formation secondary sealing area, the outer peripheral surface of described rotating ring arranges groove, spline sheet is set in a groove, sheathed spring on spline sheet outer peripheral surface, rotating ring is pressed to stationary ring by spring, described rotating ring is made up of ethylene propylene rubber material, owing to increasing straight rotor at the outer peripheral surface of rotating ring, avoid the phenomenon of drive sleeve fracture in prior art, improve the quality of mechanism seals structure, described impeller comprises wheel disc, wheel disc central authorities are provided with axis hole, described wheel disc has upper surface and lower surface, at the upper surface of wheel disc, five blades are installed, one end of described blade is connected on wheel disc, the other end is connected on wheel hub, three-dimensional flow parabola catch is installed between described adjacent blades, runner is formed between described three-dimensional flow parabola catch and wheel disc, described wheel disc is provided with six through holes, by arranging three-dimensional flow parabola catch, defining and runner that adjacent blades interval shape is consistent, improve centrifugal lift of pump.It is large that the utility model has lift, leakage phenomenon can not occur and be convenient to the features such as mobile.
