Abstract
The invention relates to a water seal structure of an anti-dry-milling automobile water pump, wherein the water seal structure comprises an auxiliary seal ring, a corrugated pipe, a spring base, a spring, a driving base, and a water pump mechanical seal body which is composed of a friction pair and a sealing base, wherein the friction pair is composed of a moving ring and a static ring, a water storage sleeve is fixed on the sealing base, the joint of the sealing base and the water storage sleeve is provided with a sealing gasket, and the friction pair is positioned in the water storage sleeve. In the use process of the automobile water pump, if the interior of the pump lacks of a cooling fluid in a long time (30 minutes to 1 hour and 20 minutes), thereby guaranteeing the water pump to normally operate in a short time, and the failure probability of the water pump is reduced.
Description
Technical field
The present invention relates to a kind of sealing structure for water, refer in particular to a kind of auto pump sealing structure for water.
Background technique
Chinese patent once disclosed a kind of " mechanical sealing element " (China; Notification number CN2116126U; September 16 1992 day for announcing); It comprises rotating shaft, auxiliary seal ring, spring, spring seat and bellows, and the relative ring surface of rotating ring two highi degree of accuracy of rotating synchronously with the static relatively stationary ring of the pump housing with rotating shaft offsets with suitable pressure, and to form boundary friction secondary, said stationary ring and rotating shaft gapped and pass through auxiliary seal ring and the pump housing fastening; Described rotating ring and rotating shaft are gapped and synchronous with rotating shaft through 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 processed by burning aluminium pottery, and rotating ring (rotating ring) is processed by resin graphite or impregnated graphite.The applicant once invented a kind of " automobile engine cooling water pump is used mechanical seal " (China; Notification number CN201209669Y; March 18 2009 day for announcing); It comprises auxiliary seal ring, bellows, spring seat and spring, and 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 processed is placed auxiliary seal ring between retainer and the rotating ring; Place bellows in the sealing seat; Place spring seat and spring in the bellows, by on the basis of conventional silicon carbide, adding stationary ring that novel silicon carbide material that carbon graphite particle sintering forms the processes bellows of packing into, stationary ring and rotating ring composition friction pair.It is simple in structure, has reached automobile cooling water pump to anti-dry grinding of mechanical seal and anti-foreign matter performance demands.But we know: auto pump in use, when lacking cooling liquid in the pump, no matter be the friction pair which kind of material is processed, the phenomenon of all can dry grinding causes sealing surface to destroy, and causes water pump to lose efficacy.So far, can guarantee water pump normal operation in the long period (30 minutes～1 hour 20 minutes) when the neither one water pump seal lacks cooling liquid in pump, become technical problem of very having a headache of auto pump water seal industry.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective of existing technology; A kind of anti-dry grinding auto pump sealing structure for water is provided; It is in the auto pump using process; If the long period (30 minutes～1 hour 20 minutes) lacks cooling liquid in the pump, can guarantee water pump normally operation at short notice, reduce the inefficacy probability of water pump.
For achieving the above object; The solution that the present invention takes is: a kind of anti-dry grinding auto pump sealing structure for water; It comprises the mechanical water pump seal body of being made up of auxiliary seal ring, bellows, spring seat, spring, retainer, friction pair and sealing seat, and friction pair is made up of rotating ring and stationary ring, fixing retaining cover on the sealing seat; There is sealing gasket sealing seat and retaining cover joint, and friction pair is in the retaining cover.
The anti-dry grinding of this kind auto pump sealing structure for water; In the auto pump using process,, lean on the water of retaining cover the inside cooling liquid to be provided to friction pair if the interior long period (30 minutes～1 hour 20 minutes) of pump lacks cooling liquid; Prolonged the working life of water seal; Water pump can normally move in this time, reduces the inefficacy probability of water pump, has very remarkable social benefit.
Description of drawings
Fig. 1 is the structural representation of present embodiment one.
Fig. 2 is the structural representation of present embodiment two.
Among the figure: 1, auxiliary seal ring, 2, the retaining cover, 3, sealing gasket, 4, bellows, 5, spring seat, 6, spring, 7, retainer, 8, rotating ring, 9, stationary ring, 10, sealing seat.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is remake description.
Referring to Fig. 1 and Fig. 2; A kind of anti-dry grinding auto pump sealing structure for water; It comprises the mechanical water pump seal body of being made up of auxiliary seal ring 1, bellows 4, spring seat 5, spring 6, retainer 7, friction pair and sealing seat 10, and friction pair is made up of rotating ring 8 and stationary ring 9, on the sealing seat 10 fixedly retaining overlap 2; Sealing seat 10 overlaps 2 joints with retaining has sealing gasket 3, and friction pair is in the retaining cover 2.
Referring to Fig. 1 and Fig. 2; The friction pair of present embodiment---rotating ring 8 all is to be processed by the novel silicon carbide material (two material with carbon element) that adding carbon graphite particle sintering on the basis of conventional silicon carbide forms with stationary ring 9; Two carbon have good anti-hard foreign matter and wear-resisting property; Retainings through in the retaining cover 2 can prevent the friction pair dry friction, it in the auto pump using process, if in the pump long period ((30 minutes～1 hour 20 minutes)) lack cooling liquid; Water pump can normally move 30 minutes to 1 hour 20 minutes, reduces the inefficacy probability of water pump.
Referring to Fig. 1 and Fig. 2, the spring 6 among the embodiment one is a cylindrical spring, and the spring 6 among the embodiment two is the wave mode spring.
