Abstract

The utility model relates to a radial sealing structure of an oil baffling pipe of a thrust bearing on a hydraulic generator. The sealing structure has the characteristics of safety, reliability and high stability. A packing ring of the sealing structure is arranged on a packing ring seat that is positioned on the outer circle of the oil baffling pipe, and forms the radial sealing structure for a rotary gap together with the bottom of the inner-circle part of a rotary runner plate. The radial sealing structure has simple installation and maintenance without abrasion, serves the purpose of improving the sealing of the thrust bearing through the improvement of the sealing structure of the oil baffling pipe, and is applied to the fields such as large-size vertical hydraulic generator, etc.

Description

Hydraulic generator thrust bearing retaining oil pipe radial seal structure
Technical field
The utility model relates to a kind of hydraulic generator thrust bearing retaining oil pipe radial seal structure.
Background technique
The sealing of lubricant oil is an important technology of large vertical water turbine generator thrust-bearing, can the service behaviour of thrust-bearing sealing is directly connected to motor safe operation, traditional sealing configuration easily leaks, maintenance is big, ecotope is caused very big threat, and adopting new retaining oil pipe sealing configuration is the effective way that addresses this problem.
Summary of the invention
The purpose of this utility model is to disclose a kind of hydraulic generator thrust bearing retaining oil pipe radial seal structure, have safe and reliable, the characteristics that stability is high, the purpose of this utility model is achieved through the following technical solutions: seal ring is installed on the seal ring seat of retaining oil pipe cylindrical, forms the rotary gap radial seal structure with the bottom surface that rotation runner plate inner circular part divides.Advantage of the present utility model is: install, overhaul the simple wearing and tearing of not having, by the improvement of retaining oil pipe sealing configuration, reach and improve the purpose that thrust-bearing seals, be applicable to fields such as large vertical water turbine generator.
