Description
Technical field:
The utility model belongs to water pump, particularly relates to a kind of radial seal water pump.
Technical background:
Seepage is one of normal fault that produces of machinery, the especially seepage of water pump.Cause the reason of seepage to mainly contain two aspects: the one, because the result of machining, the surface of engineering goods certainly exists various defectives and shape and size deviation, therefore, can produce the gap inevitably in the mechanical parts connection place; The 2nd, there is pressure difference in the sealing both sides, and working medium will pass through the gap and seepage.Therefore reducing or eliminating the gap is the main path that stops seepage.The effect of sealing is exactly that the gap between the mating face is sealed, and isolates or the cut-out leakage passage, increases the resistance in the leakage passage, perhaps in passage, add small-sized acting element, to the effusion build-up of pressure, offset or complete equilibrium with the voltage difference part that causes seepage, to stop seepage.
At present, existing water pump gland pattern is a lot, the different encapsulating method of general employing, will use different Sealings, the mechanical water pump sealing is exactly a kind of (as shown in Figure 1) comparatively commonly used, promptly in the cavity of water pump body (2) and water pump spindle (3) formation, be installed with mechanical seal device (8) and little sealing gasket (1), described mechanical seal device (8) bottom is positioned at water pump body (2), top is stretched in the impeller (6), on the water pump body (2) between described mechanical seal device (8) and the little sealing gasket (1), have draining/oil hole (5), described mechanical seal device (8) adopts stuffing box gland, seal, spring seat, spring, a plurality of parts such as rotating ring carry out combination seal, the seepage that this device adopts axial end face seal to prevent sealing, its sealing surface lays respectively at the corresponding end-faces of water pump body and impeller.
The shortcoming of existing water pump packing is: 1, structure is complicated, and its sealing surface lays respectively at the corresponding end-faces of water pump body and impeller, thereby it is higher that the relative dimensions of water pump body and impeller is made processing request; 2, installation and replacing are cumbersome, and require the workman that certain mounting technique level is arranged; When 3, the contingency accident taking place, handle difficulty; 4, one-time investment height.
The model utility content:
The purpose of this utility model is to propose a kind of mounting or dismounting of being convenient to, and is easy to breakdown maintenance, good sealing effect and radial seal water pump with low cost.
For achieving the above object, the technical solution of the utility model is: design a kind of radial seal water pump, in the cavity of water pump body and water pump spindle formation, be installed with big sealing gasket and little sealing gasket, described big sealing gasket is positioned at the port of water pump body, and near impeller, on the water pump body between described big sealing gasket and the little sealing gasket, have draining/oil hole, its main points: described big sealing gasket central authorities are provided with the water seal hole, described water seal hole inwall is the lip shape, the periphery in this water seal hole is provided with circular groove, on described circular groove cell wall, spring is housed, this spring band is on the water seal hole wall, the lip of described big sealing gasket is close to the enterprising conduct of water pump spindle to sealing, adopts this structure, and use lip radially seals the seepage of water, the lip of the water seal of oil seal type structure contacts with the water pump spindle surface, the lip line of water seal is fitted on the water pump spindle surface of rotation, thereby stop the seepage of water, and sealing effect is better when described big sealing gasket upper-end surface is equal with described water pump body upper-end surface.
Described big sealing gasket and little sealing gasket are the lips rubber gasket, and this big sealing gasket and little sealing gasket install in opposite directions, the seepage of the anti-sealing of big sealing gasket, and little sealing gasket prevents the seepage of oil.
Effect of the present utility model is: novelty simple in structure, with low cost, the fault and the water leakage phenomenon that reduce water pump greatly are difficult for taking place.
