Abstract
The utility model relates to a diesel machine water pump mechanical seal device; a water seal seat is fixed and arranged in a bearing groove on the back of a water pump impeller; the water seal seat is provided with a water seal framework; the water seal framework is provided with a dynamic ring made of graphite material; the rear end of the dynamic ring is provided with a spring; a static ring seat is fixed on a water pump body by a bolt; a static ring made of ceramics is fixed and arranged in the static ring seat; the end face of the static ring and the end face of the dynamic end face contact and form a friction pair. The utility model mounts a water seal assembly component with dynamic ring made of graphite to the impeller to rotate together, so as to have longer service life; once a draining hole of the water pump is found to leak, the impeller is removed from a pump cover and the dynamic ring is directly replaced; therefore, the removal and installation are very convenient and the utility efficiency of the diesel machine is improved.
Description
Technical field
The utility model relates to the pump technology field, particularly relates to a kind of mechanical seal device of diesel pump.
Background technique
Cooling water pump of diesel engine need be prevented the leakage of sealing with the axle envelope.Existing diesel pump axle envelope adopts mostly and is paired into the mechanical seal device of fastness by graphite-rubber, graphite-metal, and the graphite water seal that will be easy to wear and tear is installed on the water pump body as stationary ring.The mechanical seal device sealing effect of this structure is relatively poor, and working life is short, changes more frequently, and particularly repair and replacement dismounting inconvenience influences the complete machine utilization efficiency of diesel engine.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of good seal performance, long service life, repair and replacement diesel pump mechanical seal device easily is provided, to improve the complete machine utilization efficiency of diesel engine.
The technical solution of the utility model is: it comprises water pump body, is installed in water pump spindle in the water pump body and the impeller that is installed in the water pump spindle end, the groove internal fixation that takes up at the impeller back side is equipped with the water seal seat, interference is equipped with the water seal skeleton in the water seal seat, in the water seal skeleton, rotating ring is installed, the intraskeletal spring that rotating ring is compressed forward of the water seal of being contained in is arranged in the rotating ring rear end.By bolt stationary seat is arranged on water pump body, at the stationary seat internal fixation stationary ring is installed, the stationary ring end face contacts with the rotating ring end face and constitutes a fastness.
Diesel pump mechanical seal device as mentioned above, its stationary ring is by ceramic material, and its rotating ring is made by graphite material.
Diesel pump mechanical seal device as mentioned above is installed in the rubber pad in the stationary seat in addition at the back side of stationary ring, scribble adhesive glue on the two sides of rubber pad.
The utility model will be that the water-sealed component of rotating ring is installed on the impeller and rotates with impeller with graphite, the static components that will be stationary ring with the pottery is fixed on the water pump body, form a graphite-ceramic fastness, good sealing effect, long service life has leakage phenomenon as long as find the water pump spilled water hole, pull down impeller from pump cover, directly change rotating ring and get final product, remove and install very conveniently, improved the diesel engine utilization efficiency.
Description of drawings
Fig. 1 is a main sectional view of the present utility model, shows its overall structure.
Embodiment
The accompanying drawing illustrated embodiment, the utility model comprises water pump body 9, is installed in the water pump spindle 7 in the water pump body 9 and is installed in the axle sleeve 8 that therewith rotates on the water pump spindle 7, in water pump spindle 7 ends impeller 1 is installed, take up at impeller 1 back side that interference is equipped with water seal seat 2 in the groove, interference is equipped with water seal skeleton 11 in water seal seat 2, the rotating ring of being made by graphite material 3 is installed in water seal skeleton 11, the spring 10 that rotating ring 3 is compressed forward that is contained in the water seal skeleton 11 is arranged in rotating ring 3 rear ends.By bolt stationary seat 6 is arranged on water pump body 9, at stationary seat 6 internal fixation stationary ring 4 by ceramic material is installed, the end face of stationary ring 4 contacts with the end face of rotating ring 3 and constitutes a pair of fastness.The back side of stationary ring 4 is installed in the rubber pad 5 in the stationary seat 6 in addition, scribbles adhesive glue on the two sides of rubber pad 5, so that stationary ring 4, rubber pad 5, stationary seat 6 threes are tightened together.
