Abstract
The utility model discloses a water storage type car water pump unit, which comprises a belt wheel (1), a water pump body (2), an impeller shaft (3), a water seal assembly (4) and an impeller (5); the water pump body (2) is provided with an evaporation hole (6) and a water discharging hole (7); and a water storage tank (8) is disposed close to the water discharging hole (7) on the water pump body (2). The leaked cooling liquid between a moving ring and a static ring of the water seal assembly will be stored in the water storage tank; as long as the water seal assembly is not damaged, the leaked cooling liquid is a small amount of liquid and will not flow out of the water storage tank but is evaporated by temperature of the water pump unit. Slight normal leakage of water pump is avoided being mistaken for a damaged water pump by customers, so that complaint rate of customers on products is reduced, cost of this pump unit is almost the same as that of the original pump unit, and market competitiveness of product is improved.
Description
Technical field
The present invention relates to a kind of motor car engine water cooling system, specifically relate to a kind of auto pump assembly.
Background technique
At present, the auto pump assembly is by formations such as water pump body, impeller shaft (containing bearing), water-sealed component, impellers, and its water-sealed component is a kind of dynamic mechanical seal, is the relative sealing between rotating ring, the stationary ring, rather than positive confinement.
When auto pump assembly (abbreviation water pump) when just using; Because rotating ring in its water-sealed component and stationary ring have a relative process of grinding; So when having the water-sealed component of only a few water pump can occur to quit work, have the phenomenon that cooling liquid is oozed out between water seal rotating ring and stationary ring; When pump working after a period of time, the relative movement of water seal rotating ring and stationary ring reaches grinds smooth state, will eliminate cooling liquid seepage phenomenon; When water pump works long hours; Because have the rotten crystal that has of impurity or cooling liquid to generate in the cooling liquid, if the rubbing surface that impurity or crystal get between rotating ring and stationary ring can cause the slight phenomenon that scratches in water sealing stationary ring surface, so also can cause between water seal rotating ring and stationary ring has cooling liquid to ooze out phenomenon; But pump working is after a period of time; The relative grinding of water seal rotating ring and stationary ring again can be smooth with the slight scuffing reparation on the stationary ring, and water pump seal assembly seepage phenomenon will stop.If stationary ring scratches serious, the relative grinding of water seal rotating ring and stationary ring can't be repaired this scuffing plane, and then the serious seepage cooling liquid of this water pump meeting causes water pump to scrap.
Damage impeller shaft (containing bearing) in order to prevent the cooling liquid that water seal rotating ring and stationary ring leak out; Usually can on the pump housing between the bearing of water-sealed component and impeller shaft, be designed with spilled water hole and evaporation apertures; Purpose is that the water vapour of revealing between water seal rotating ring and stationary ring is volatilized away through evaporation apertures, and the cooling liquid of seepage between rotating ring and stationary ring is flowed out through spilled water hole.After cooling liquid flows out from spilled water hole, the vestige phenomenon that can cause the spilled water hole of water pump body to have cooling liquid to flow out, client will think that water pump leaks and damage, and needs more water-change pump and produces the complaint mood.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and a kind of water storage type auto pump assembly that can the cooling liquid that leak out between the rotating ring of water-sealed component and stationary ring be stored natural evaporation then earlier is provided.
The object of the invention is realized through following technological scheme: a kind of water storage type auto pump assembly; Comprise belt pulley, water pump body, impeller shaft, water-sealed component, impeller; Water pump body is provided with evaporation apertures and spilled water hole, on said water pump body and be provided with water storage tank near the spilled water hole place.
After adopting structure of the present invention, the cooling liquid of seepage can be stored in the water storage tank between the rotating ring of water-sealed component and stationary ring, as long as water-sealed component does not damage, the cooling liquid of seepage is that small amount of liquid just can not overflow water storage tank, but is evaporated by the temperature of water pump complement.Therefore avoided the slight normal seepage of water pump and be misinterpreted as the water pump damage, reduced client's the rate of complaints, and its cost has been also similar with former pump housing cost, thereby has improved the competitiveness of product in market product by client.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the present invention is made further detailed description.
Fig. 1 is the structural representation of water storage type auto pump assembly.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment
Can know with reference to Fig. 1, Fig. 3; Water storage type auto pump assembly of the present invention; Comprise belt pulley 1, water pump body 2, impeller shaft 3 (containing bearing is one), water-sealed component 4 (comprising water seal rotating ring 41, water sealing stationary ring 42), impeller 5; Water pump body 2 is provided with evaporation apertures 6 and spilled water hole 7, on said water pump body 2 and be provided with water storage tank 8 near spilled water hole 7 places.
Wherein, have two imports 9, outlet 10 (like Fig. 1, shown in Figure 2) on the water pump body 2; One end of impeller shaft 3 is equipped with belt pulley 1, and its other end is equipped with water-sealed component 4 and impeller 5; Said water storage tank 8 is exactly through on water pump body 2, increasing the groove that can store cooling liquid near spilled water hole 7 places, and this water storage tank position must be positioned at the front side of the spilled water hole 7 of water pump body, and spilled water hole 7 must communicate with water storage tank 8.The cooling liquid of seepage can be stored into earlier in the water storage tank between water seal rotating ring of the present invention and water sealing stationary ring, as long as water-sealed component does not damage, the cooling liquid of seepage just can not overflowed this water storage tank, but is evaporated by the temperature of water pump.Have only when cooling liquid accumulates and just can from spilled water hole, release when too much.Existing this water pump body structure is used on the water pump of Guangxi Yuchai Machinery Co., Ltd., has obtained the favorable comment of Yuchai.
