Abstract
The utility model relates to a mechanical sealing device used for a cooling water pump of an automobile engine, which comprises an auxiliary sealing ring, a corrugated tube, a spring seat and a spring. A moving ring made of novel silicon carbide material which is formed by sintering carbon graphite particle added into conventional silicon carbide is positioned in a transmission seat; the auxiliary sealing ring is positioned between the transmission seat and the moving ring; the corrugated tube is arranged in a sealing seat, the spring seat and the spring are positioned in the corrugated tube; a static ring made of novel silicon carbide material which is formed by sintering carbon graphite particle added into conventional silicon carbide is positioned in the corrugated tube; the static ring and the moving ring form a friction pair. The mechanical sealing device has a simple structure, and meets the requirement of dry grind proof performance and foreign body proof performance of the automobile cooling water pump to the mechanical sealing device.
Description
Technical field
The utility model relates to a kind of mechanical seal, refers in particular to a kind of automobile engine cooling water pump mechanical seal.
Technical background
At present, the mechanical sealing element friction pair pairing that is used for automobile engine cooling water pump generally has following three kinds: first kind be silicon carbide to graphite, second kind be aluminium oxide to graphite, the third is that conventional silicon carbide is to micro-pore silicon carbide.First kind and second kind pairing self-lubricating property is better, but anti-foreign matter poor performance.It is good that the third matches anti-foreign matter performance, but anti-dry grinding property is poor.A very long time, the rate of fault of motor car engine industry cooling waterpump mechanical seal is high, perplexing the development of China's automobile cooling system, some producer selects the mechanical sealing element of external famous brand name for use, but its anti-dry grinding is not good with the General of anti-foreign matter, reason has following 3 points: (1) owing to the quality ginseng of the selected engine antifreeze coolant liquid of domestic engine works is inferior uneven, its crystallization exceeds standard, and has destroyed rubbing surface; (2) cooling system pipeline cleaning inside degree is poor, and casting sand, corrosion oxide enter cooling liquid and destroyed rubbing surface; (3) because of water pump packing dry grinding phenomenon appears in a variety of causes, cause sealing surface to destroy.
Chinese patent once disclosed a kind of " mechanical sealing element " (CN2116126U, September 16 1992 day for announcing), it comprises rotating shaft, auxiliary seal ring, spring, spring seat and bellows, it is characterized in that: the relative ring surface of rotating ring two highi degree of accuracy of rotating synchronously relative to static stationary ring with rotating shaft with the pump housing offsets with suitable pressure and forms the boundary friction pair, and said stationary ring and rotating shaft are gapped and fastening by the auxiliary seal ring and the pump housing; Described rotating ring and rotating shaft are gapped and synchronous with rotating shaft by the bellows cooperation maintenance that is anchored in the rotating shaft, and spring is placed between throw-out collar and the spring seat.Its stationary ring is made by burning aluminium pottery, and rotating ring (rotating ring) is made by resin graphite or impregnated graphite.
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of automobile engine cooling water pump mechanical seal is provided, and it has reached automobile cooling water pump to anti-dry grinding of mechanical seal and anti-foreign matter performance demands.
The model utility content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of automobile engine cooling water pump mechanical seal is provided, and it is simple in structure, has reached automobile cooling water pump to anti-dry grinding of mechanical seal and anti-foreign matter performance demands.
For achieving the above object, the solution that the utility model is taked is: a kind of automobile engine cooling water pump mechanical seal, it comprises auxiliary seal ring, bellows, spring seat and spring, the rotating ring that the novel silicon carbide material that placement is formed by adding carbon graphite particle sintering on the basis of conventional silicon carbide in the retainer is made, place auxiliary seal ring between retainer and the rotating ring, place bellows in the sealing seat, place spring seat and spring in the bellows, by add stationary ring that novel silicon carbide material that carbon graphite particle sintering forms the makes bellows of packing on the basis of conventional silicon carbide, stationary ring and rotating ring are formed friction pair.
The utility model is simple in structure, because stationary ring and rotating ring are all made by the novel silicon carbide material that adding carbon graphite particle sintering on the basis of conventional silicon carbide forms, improved self-lubricating property, can resistive connection brilliant particle and foreign matter can resist dry grinding again, owing in bellows, place spring, stationary ring and rotating ring surface contact and have suitable pressure, sealability is reliable, has reached the requirement of automobile cooling water pump to the anti-dry grinding of mechanical seal and anti-foreign matter performance and sealability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, retainer, 2, auxiliary seal ring, 3, rotating ring, 4, stationary ring, 5, bellows, 6, spring, 7, spring seat, 8, sealing seat, 9, pump shaft.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, a kind of automobile engine cooling water pump mechanical seal, it comprises auxiliary seal ring 2, bellows 5, spring seat 7 and spring 6, the rotating ring 3 that the novel silicon carbide material that placement is formed by adding carbon graphite particle sintering on the basis of conventional silicon carbide in the retainer 1 is made, place auxiliary seal ring 2 between retainer 1 and the rotating ring 3, place bellows 5 in the sealing seat 8, place spring seat 7 and spring 6 in the bellows 5, by add stationary ring 4 that novel silicon carbide material that carbon graphite particle sintering forms the makes bellows 5 of packing on the basis of conventional silicon carbide, stationary ring 4 and rotating ring 3 are formed friction pairs.
During use, retainer 1 is pressed into the pump shaft 9 of automobile engine cooling water pump, and retainer and rotating ring wherein 3 rotate synchronously with pump shaft 9.
