Problems solved by technology
However, we know that during the use of the automobile water pump, when there is a lack of cooling liquid in the pump, no matter what kind of material the friction pair is made of, dry grinding will occur, causing damage to the sealing surface and causing the pump to fail
So far, no water pump water seal can guarantee the normal operation of the water pump for a long time (30 minutes to 1 hour and 20 minutes) when there is a lack of cooling liquid in the pump, which has become a very headache technical problem in the automotive water pump water seal industry.

Embodiment Construction
[0009] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0010] see figure 1 with figure 2 , an anti-dry wear automobile water pump water seal structure, which includes a water pump mechanical seal body composed of an auxiliary sealing ring 1, a bellows 4, a spring seat 5, a spring 6, a transmission seat 7, a friction pair and a seal seat 10, and the friction pair It is composed of a moving ring 8 and a static ring 9. The water storage sleeve 2 is fixed on the sealing seat 10. There is a sealing gasket 3 at the joint between the sealing seat 10 and the water storage sleeve 2. The friction pair is in the water storage sleeve 2.
[0011] see figure 1 with figure 2 , the friction pairs of this embodiment—the moving ring 8 and the static ring 9 are all made of a new type of silicon carbide material (double carbon material) that is sintered on the basis of conventional silicon carbide by adding carbon graphit...

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 [0001] The invention relates to a water seal structure, in particular to an automobile water pump water seal structure. Background technique [0002] A Chinese patent once disclosed a "mechanical seal" (China, announcement number CN2116126U, announcement date September 16, 1992), which includes a rotating shaft, auxiliary sealing ring, spring, spring seat and bellows, and is relatively stationary with the pump body The two high-precision relative annular surfaces of the stationary ring and the rotating ring that rotate synchronously with the rotating shaft are offset by an appropriate pressure to form a boundary friction pair. The stationary ring and the rotating shaft have a gap and are fastened to the pump body through an auxiliary sealing ring; There is a gap between the rotating ring and the rotating shaft, and the bellows fastened on the rotating shaft are matched to keep synchronous with the rotating shaft, and the spring is placed between the push ring...
