Abstract
The utility model discloses a wear-resistant water seal used for a water pump of a diesel engine. The water seal used for water pumps of the diesel engine comprises a water seal body, a stationary water seal ring, a movable water seal ring, a corrugated tube and a corrugated tube seat, wherein the corrugated tube seat is arranged on the water seal body; the corrugated tube is arranged on the corrugated tube seat; one end of the corrugated tube seat is connected with a water seal mounting washer, and the other end thereof is connected with the stationary water seal ring; the water seal body is provided with the movable water seal ring close to the stationary water seal ring; the sealed surface of the movable water seal ring is a seal belt made of silicon carbide; and the sealed surface of the stationary water seal ring is a seal belt made of silicon carbide. As for the water seal for water pumps of the diesel engine, the sealed surfaces of the movable water seal ring and the stationary water seal ring are made of silicon carbide, thus improving the friction resistance of the water seal.
Description
Technical field
The utility model relates to a kind of water seal, particularly a kind of water seal that is applied to diesel pump.
Background technique
As everyone knows, the motor that relies on cooling liquid to cool off needs water pump that suitable flow and lift is provided usually, during pump working, needs water seal to sealing between the water pump bearing and the pump housing usually.The water seal of diesel pump generally includes corrugated header, bellows, spring seat, spring, stationary ring, rotating ring, auxiliary seal ring and bearing.The corrugated header of water seal is installed in the mounting hole of pump body, is connected in the water sealing stationary ring of one by spring compression and with corrugated header, constitutes sealing configuration with the rotating ring that is attached to axle sleeve, and its Intermediate shaft sleeve adopted win to cooperate with water pump bearing.Water seal axle sleeve and rotating ring be together rotation under the drive of water pump bearing, and stationary ring is fitted with the water seal rotating ring under the compressing of spring all the time, thereby constitutes the water pump rotation down to the sealing of cooling liquid.
At present, the water seal of domestic diesel engine water pump, its water sealing stationary ring adopts the softer graphite of quality, so after entering foreign matter between water seal rotating ring and the water sealing stationary ring, be easy to scratch the water sealing stationary ring of ink material, destroy the planeness and the roughness of sealing surface between water seal rotating ring and the water sealing stationary ring, and finally caused the seal failure of water seal.
The model utility content
The purpose of this utility model is the water seal that discloses a kind of wear-resistant function, is applied in the diesel pump.
The water seal of diesel pump described in the utility model, comprise water seal body, water sealing stationary ring, water seal rotating ring, bellows and corrugated header, corrugated header is arranged on the water seal body, corrugated header is provided with bellows, one end of corrugated header is installed seat ring with water seal and is linked to each other, the other end links to each other with water sealing stationary ring, on the water seal body, next-door neighbour water sealing stationary ring be provided with the water seal rotating ring, the sealing surface of water seal rotating ring is the sealing strip that silicon carbide is made, and the sealing surface of ink stationary ring is the seal band that silicon carbide is made.
Wherein, scribble skim lubricating grease between water sealing stationary ring and the water seal rotating ring.
Wherein, on bellows, also be provided with the spring that is used for providing pretightening force to water sealing stationary ring and water seal rotating ring.
Wherein, the side near water sealing stationary ring also is provided with first spring seat that is used for clamping water seal rotating ring on bellows.
Wherein, also be provided with auxiliary seal ring in the outside of water seal rotating ring.
Wherein, be provided with axle sleeve in the outside of auxiliary seal ring.
The water seal of diesel pump of the present utility model has following beneficial effect:
1, after the sealing surface of water seal rotating ring and water sealing stationary ring adopts silicon carbide, improved the ability of the friction resistant of water seal;
2, after the sealing surface between water seal rotating ring and the water sealing stationary ring is smeared skim lubricating grease, improved under the condition that does not have cooling liquid the dry friction ability between water seal rotating ring and the water sealing stationary ring.
Description of drawings
Fig. 1 is the structure sectional view of the water seal of the utility model diesel pump.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
1-water seal body, 2-second spring seat, 3-corrugated header, 4-spring, 5-bellows, 6-first spring seat, 7-water sealing stationary ring, 8-water seal rotating ring, 9-axle sleeve, 10-auxiliary seal ring.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
As shown in Figure 1, the water seal of the utility model diesel pump comprises water seal body 1, water seal body 1 is provided with corrugated header 3, one end of corrugated header 3 is installed seat ring by water seal and is linked to each other with water pump, the other end links to each other with water sealing stationary ring 7, on corrugated header 3, be provided with bellows 5, on water seal body 1, next-door neighbour's water sealing stationary ring 7 is provided with water seal rotating ring 8, the sealing surface of water seal rotating ring 8 is the sealing strip that silicon carbide is made, the sealing surface of ink stationary ring 7 is the seal band that silicon carbide is made, silicon carbide has high hardness and wear resistance, can prevent the damage of foreign matter to the sealing surface between water seal rotating ring and the water sealing stationary ring.
Sealing surface between water sealing stationary ring 7 and water seal rotating ring 8 also scribbles skim lubricating grease.Therefore can guarantee between water seal rotating ring and the water sealing stationary ring when not having the cooling liquid cooling, can prolong the time of the anti-dry friction of water seal, when helping solving motor and dispatching from the factory test-run a machine, cause the water seal dry friction owing to the stand cooling system can not in time supply water, thereby the rubber material bellows that prevents the high heat burnout water seal that dry friction produces causes the water seal seal failure to be leaked.
On bellows 5, be provided with spring 4, be used between water sealing stationary ring 7 and water seal rotating ring 8, providing pretightening force, both are close to.Side near water sealing stationary ring 7 on bellows 5 is provided with first spring seat 6, is used for firm clamping water seal rotating ring 8, on bellows 5, be provided with second spring seat 2 with first spring seat, 6 relative sides, be used for fixing bellows 5 is installed.Be provided with axle sleeve 9 in the outside of water seal rotating ring 8, between water seal rotating ring 8 and axle sleeve 9, also clamped auxiliary seal ring 10.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
