Abstract
The invention relates to a bearing water cooling system of a water pump, comprising a pump body and a pump shaft, wherein, a bearing is arranged in the pump body, the pump shaft is arranged in the bearing, and the connection end face of the bearing and the inner cavity of the pump body is provided with a bearing cover; and the pump shaft penetrates through the shaft axis of the bearing cover, a cooling water chamber is arranged in the bearing cover, each bearing cover is provided with a water inlet passage and a water return passage, and one end of the water inlet passage and one end of the water return passage are respectively communicated with the cooling water chamber. A cooling water circulation pipeline is arranged on the pump body, and the other end of the water inlet passage and the other end of the water return passage are respectively connected with the cooling water circulation pipeline. The invention has the structure that the cooling water chamber is arranged in the bearing cover of the water pump with the grease lubrication bearing support structure, and cooling water is utilized to take away the heat transferred from the pump end to the bearing end and the heat produced in the working of the bearing, so that the temperature rise of the bearing end is reduced, the bearing working environment is improved, and the technical problem that the pump with the grease lubrication bearing support structure can not deliver media with higher temperature is solved.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to pump, particularly a kind of bearing constituent of water pump.
Background technique:
In the pump series products, send the influence of medium temperature, bearing needs different lubricating systems.In the prior art, the pump of the medium of conveying lower temperature adopts the bearing support structure of grease lubrication, and the pump of the medium of conveying higher temperature adopts the bearing support structure of oil lubrication.The bearing support structure of grease lubrication is different with the bearing support structure of oil lubrication.Therefore when the pump that need utilize the grease lubricating bearing supporting structure is carried the medium of higher temperature, can only redesign by the bearing support structure of oil lubrication, the die sinking tool has improved cost of production again.
Summary of the invention:
The bearing constituent that the purpose of this invention is to provide a kind of water pump, the bearing constituent of described this water pump will solve the technical problem that the pump of available technology adopting grease lubricating bearing supporting structure can not be carried the higher temperature medium.
The bearing constituent of this water pump of the present invention is made of the pump housing and pump shaft, be provided with bearing in the described pump housing, described pump shaft is arranged in the bearing, bearing is provided with bearing gland with the end face that is connected of pump housing inner chamber, pump shaft passes from the axle center of described bearing gland, wherein, Packed cooling water cavity volume is set in the described bearing gland, be provided with an intake tunnel and a backwater channel in the outer wall of described cooling water cavity volume, an end of described intake tunnel and an end of backwater channel are communicated with the cooling water cavity volume respectively.
Further, the described pump housing is provided with the cooling water circulating line, and the other end of described intake tunnel is connected with the cooling water circulating line respectively with the other end of backwater channel.
Working principle of the present invention is: be provided with the cooling water cavity volume in the bearing gland, during pump work, the current in the cooling water circulating line are through the cooling water cavity volume, and the pump end passes to the heat of bearing end and the heat that bearing working itself produces, and absorbs by cooling water and takes away.Reduce the temperature rise of bearing end, improved the working environment of bearing.Greatly improve the working life of bearing, reduced the user cost of product, expanded the using scope of unit.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention is provided with the cooling water cavity volume in the bearing gland of the water pump of grease lubricating bearing supporting structure, utilize cooling water to take away the pump end and pass to the heat of bearing end and the heat that bearing working itself produces, reduced the temperature rise of bearing end, improve the working environment of bearing, solved the technical problem that the pump that adopts the grease lubricating bearing supporting structure can not be carried the higher temperature medium.
Description of drawings:
Fig. 1 is the structural representation of the bearing constituent of water pump of the present invention.
Embodiment:
As shown in Figure 1, the bearing constituent of water pump of the present invention is made of the pump housing 1 and pump shaft 2, be provided with bearing 3 in the described pump housing 1, described pump shaft 2 is arranged in the bearing 3, bearing 3 is provided with bearing gland 4 with the end face that is connected of the pump housing 1 inner chamber, pump shaft 2 passes from the axle center of described bearing gland 4, wherein, Packed cooling water cavity volume 5 is set in the described bearing gland 4, be provided with an intake tunnel and a backwater channel in the outer wall of cooling water cavity volume 5, an end of described intake tunnel 6 and an end of backwater channel 7 are communicated with cooling water cavity volume 5 respectively.
Further, the described pump housing 1 is provided with cooling water circulating line (not shown), and the other end of the other end of described intake tunnel 6 and backwater channel 7 is connected with the cooling water circulating line respectively.
Working procedure of the present invention is: be provided with cooling water cavity volume 5 in the bearing gland 4, during pump work, current in the cooling water circulating line are through cooling water cavity volume 5, and the pump end passes to the heat of bearing 3 ends and the heat that bearing 3 work itself produce, and absorb by cooling water and take away.Reduce the temperature rise of bearing 3 ends, improved the working environment of bearing 3.Greatly improve the working life of bearing 3, reduced the user cost of product, expanded the using scope of unit.
Claims (2)
1. the bearing constituent of a water pump, constitute by the pump housing and pump shaft, be provided with bearing in the described pump housing, described pump shaft is arranged in the bearing, bearing is provided with bearing gland with the end face that is connected of pump housing inner chamber, pump shaft passes from the axle center of described bearing gland, it is characterized in that: Packed cooling water cavity volume is set in the described bearing gland, be provided with an intake tunnel and a backwater channel in the outer wall of described cooling water cavity volume, an end of described intake tunnel and an end of backwater channel are communicated with the cooling water cavity volume respectively.
