Abstract
The utility model relates to a cooling structure for a water pump bearing, which comprises a pump body and a pump shaft, wherein the pump body is equipped with a bearing, the pump shaft is arranged in the bearing, a bearing pressure cover is arranged on a connecting end surface of the bearing and the inner cavity of the pump body, the pump shaft passes through the axis of the bearing pressure cover, a cooling water square-cavity is arranged in the bearing pressure cover, a water inlet channel and a backwater channel are arranged on the bearing pressure cover, and one end of the water inlet channel and one end of the backwater channel are respectively communicated with the cooling water square-cavity. A cooling water circulating pipe is arranged on the pump body, and the other end of the water inlet channel and the other end of the backwater channel are respectively connected with the cooling water circulating pipe. The cooling water square-cavity is arranged in the bearing pressure cover of a water pump of a grease lubrication bearing supporting structure, the heat which is transferred to a bearing end by a pump end and the heat which is produced by the working of the bearing are brought away by cooling water, thereby reducing the temperature rise of the bearing end, improving the work environment of the bearing, and solving the technical problems that a pump which uses the grease lubrication bearing supporting structure is not capable of transporting high temperature medium.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to pump, particularly a kind of cooling structure that is used for water pump bearing.
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 purpose of this utility model provides a kind of cooling structure that is used for water pump bearing, the technical problem that the pump that the described this cooling structure that is used for water pump bearing will solve available technology adopting grease lubricating bearing supporting structure can not be carried the higher temperature medium.
This cooling structure that is used for water pump bearing of the present utility model 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, be provided with the cooling water cavity volume in the described bearing gland, bearing gland is provided with an intake tunnel and a backwater channel, and 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 utility model is: be provided with the cooling water cavity volume in the bearing gland, during pump work, 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 absorb by cooling water and take 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 utility model and prior art contrast, and its effect is actively with tangible.The utility model 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 that is used for the cooling structure of water pump bearing of the present utility model.
Embodiment:
As shown in Figure 1, the cooling structure that is used for water pump bearing of the present utility model 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, be provided with cooling water cavity volume 5 in the described bearing gland 4, bearing gland 4 is provided with an intake tunnel 6 and a backwater channel 7, and 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 utility model 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.
