Abstract
The utility model relates to the technical field of water wheel generator equipment, in particular to a bearing bush of a pedestal bearing. A water internal cooling bearing bush of a pedestal bearing comprises a bearing bush and a cooling pipeline arranged inside the bearing bush, wherein the cooling pipeline is connected with external cooling water through a pipe. The bearing bush has the advantages that during the operation, the cooling water is introduced, the heat generated by the friction between a bush surface and a rotating shaft is directly brought away, the cooling effect is good, the temperature rise is low, the cost is saved, and the operation reliability is also improved.
Description
Technical field
The utility model relates to the hydraulic turbine generator equipment technical field, is specifically related to a kind of bearing shell of pedestal bearing.
Background technique
Hydraulic turbine generator pedestal bearing bearing shell of the prior art comprises watt body and Babbitt, and the casting mode is adopted in the combination of watt body and Babbitt.The lubrication and cooling of bearing shell is finished by lubricating-oil self-circulating.
The problem that prior art exists is, the existing type of cooling, and at high rotating speed, large load, easy tile kilning in the large situation of pv value causes shutdown.
The conventional method that solves pedestal bearing bearing shell tile kilning problem is:
The lubricating system that the selection pressure formula is refueled strengthens the specific discharge of cold oil, could satisfy the operating conditions of pedestal bearing bearing shell.The shortcoming of this structure is as follows:
1. must increase Lubricating-oil Station, gravity tank and be communicated with oil pipe, the power station oil-way system is complicated.
2. cost is high.
Summary of the invention
The utility model provides a kind of good cooling results for the deficiencies in the prior art, the bearing bush that cost is low---water-cooled watt.
The purpose of this utility model is achieved through the following technical solutions:
A kind of internal water cooling bearing shell of pedestal bearing comprises the cooling line of bearing shell and bearing shell inside it is characterized in that described cooling line bores several circular holes at lower watt of body, described circular hole two ends are every individual milling connectivity slot, use cover plate for sealing, form M type pipeline, can the water flowing cooling.
Wherein, described several circular hole apertures, hole count and spacing are decided according to the bearing shell size.
The beneficial effects of the utility model:
A kind of internal water cooling bearing shell of pedestal bearing by the water cooling pipeline in the bearing shell watt body, allows water that the fricative heat of bearing shell is directly taken away, good cooling results, and bearing temperature rise is low, satisfies high rotating speed water turbine generator service condition.
By the internal water cooling bearing shell, realize reducing under the operating mode of the same race watt temperature more than 10 ℃, not only save cost, also improve reliability of operation.
Description of drawings
Fig. 1 is that master of the present utility model looks sectional view.
In figure one, comprise 1---lower watt of body, 2---Babbitt, 3---the water port, 4---connectivity slot, 5---the connectivity slot shrouding, 6---the discharging pipe mouth.
Fig. 2 is low brass plan view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
A kind of internal water cooling bearing shell of pedestal bearing water among Fig. 1, Fig. 2, is characterized in that described lower watt of body 1 processing water port 3, and water port 3 is linked to be cooling line by connectivity slot 4 and connectivity slot shrouding 5, but two ends are provided with discharging pipe mouth 6 connecting pipes.
The utility model passes into cooling water in when operation, and the heat that directly tiling and axis friction is produced is taken away, its good cooling results, and temperature rise is low, and the bearing capacity of bearing shell is significantly improved.
Claims (2)
1. the internal water cooling bearing shell of a pedestal bearing comprises the cooling line of bearing shell and bearing shell inside it is characterized in that described cooling line bores several circular holes at lower watt of body, described circular hole two ends are every individual milling connectivity slot, use cover plate for sealing, form M type pipeline, can the water flowing cooling.
2. the internal water cooling bearing shell of a kind of pedestal bearing according to claim 1 is characterized in that described several circular holes evenly arrange along internal diameter.
