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, easily leak; Three is that existing centrifugal pump impeller adopts inner multiple centrifugal blade spiral usually; reach working effect; because blade quantity is more; internal flow path is not smooth; frequent meeting blockage phenomenon; existing centrifugal pump impeller adopts the material manufactures such as cast iron, cast steel, stainless steel, cast copper simultaneously, although this kind of higher material of strength ratio is not corrosion-resistant, and also not resistance to cavitation.
Model utility content
The purpose of this utility model is exactly provide a kind of corrosion-resistant for above-mentioned situation, leakage phenomenon can not occur and be convenient to the corrosion resistant centrifugal pump of movement.The purpose of this utility model realizes by following scheme: a kind of corrosion resistant 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 impeller bodies, described impeller bodies is disc structure, concentric step cutting pattern is provided with above disk, described step cutting pattern is provided with concentric round column structure, concentric through hole is provided with in the middle of described round column structure, round column structure side shape has the tapped hole run through, described impeller bodies side is provided with two circular holes, described two circular holes in the shape of a spiral, circle round along running shaft, described two circular holes are not connected, part between two circular holes forms two centrifugal blades, the material of described impeller is plastic material, concentric round ring boss is provided with bottom impeller bodies, boss surface has cross bath.Owing to establishing eight diagram-shaped spiral hole structure in impeller, material is plastic material, and bearing capacity is strong, and global stability is good, and water-outlet quantity is large, strengthens decay resistance simultaneously.The utility model has corrosion-resistant, leakage phenomenon can not occur and be convenient to the features such as mobile.
