Abstract
The utility model relates to an elastic plastic bush with a high pressure oil nozzle, comprising a thrust bearing bush blank and an elastic plastic bush surface. The thrust bearing bush blank is provided with a high pressure oil inlet hermetically matched with the high pressure oil nozzle whose lower end is communicated with an oil path. The utility model breaks the traditional concept that a high pressure oil lubricating device can not be added on the elastic plastic bush, and ensures that the connecting surface of a plastic layer and a metal bush blank has no penetration of the high pressure oil; the bush surface of the plastic layer can not be peeled off; the thrust bearing is provided with favorable lubricating oil film during the overall process of starting, running and stopping of a machine set; the elastic plastic bush can not be abraded for ever.
Description
The utility model relates to a kind of thrust bearing segment of hydraulic generator unit, particularly relates to a kind of elastomeric plastics with the high pressure oil nozzle watt.
The thrust-bearing of the hydraulic generator unit of each hydroelectric station operation of China generally adopts the thrust bearing shoe valve of Babbitt, being in operation, it is lower bearing capacity to occur, Wa Wen is very high, the tile kilning accident often appears, therefore, introduced elastomeric plastics watt new material from the Soviet Union (present Russia) several years ago, this material is behind steel unbaked tile tining, the helical of burn-oning copper wire, compressing teflon is that main plastics tiling is made, the use of elastomeric plastics watt has improved the bearing capacity of unit, has reduced Wa Wen, improved the ride quality of thrust-bearing, but find that through in a few years operation elastomeric plastics watt all has wearing and tearing in various degree, even occurs because of an elastomeric plastics watt serious wear tile kilning accident taking place, for overcoming the wearing and tearing of elastomeric plastics watt, people add antiwear additive in teflon, improving its wear resistance, but this can't fundamentally solve the wear problem of elastomeric plastics watt.
The purpose of this utility model is, a kind of elastomeric plastics with high pressure nozzle watt is provided, and to overcome the deficiency of prior art, realizes that elastomeric plastics watt is not worn.
When generator set normally moves; the dynamic pressure oil film that has 0.03-0.06mm between thrust-bearing change and the thrust bearing shoe; therefore; thrust bearing shoe can not be worn; just in startup of unit or stopping process; because of rotating speed very low; can not form dynamic pressure oil film; form dry friction or semi-dry friction between thrust-bearing change and the thrust bearing shoe valve this moment, thereby the thrust tiling is worn, in other words in startup of unit or stopping process; as long as between thrust-bearing change and thrust bearing shoe valve, inject high pressure oil; form the static pressure oil film, then thrust-bearing just in the overall process of operation, all has good lubricating oil film.
Following mode can realize the utility model:
Comprise thrust-bearing unbaked tile and elastomeric plastics tiling, be provided with the high pressure oil oil inlet hole on the thrust-bearing unbaked tile, high pressure oil nozzle and high pressure oil oil inlet hole are sealed and matched, and make it non-leakage, and high pressure oil nozzle lower end communicates with oil circuit.
The high pressure oil nozzle is threaded with the high pressure oil oil inlet hole, silver soldering sealing again.
The utility model has been broken the traditional concept that elastomeric plastics watt can not install the high pressure oil lubricating fitting additional; thrust-bearing high pressure oil lubrication system can be applied on the elastomeric plastics watt; and the junction plane place of plastic layer and metal unbaked tile does not have high pressure oil and infiltrates; guarantee unit at starting operation, shut down the full greasy property of thrust-bearing in the overall process, thereby make elastomeric plastics watt never wornout.
Fig. 1 is the utility model overall structure schematic representation.
Embodiment:
In the internal thread high pressure oil oil inlet hole on steel thrust-bearing unbaked tile 1; high pressure nozzle 3 is threaded with it; after high pressure nozzle 3 is tightened on the thrust-bearing unbaked tile 1; use silver-bearing copper electrode holder 1 again; 3 weld; sealing; 30min can seepage under the 14MPa oil pressure to make it; qualified back tining on thrust-bearing unbaked tile 1; weldering spirality copper wire; and teflon is main plastics tiling 2 in the hot pressing; elastomeric plastics tiling 2 exceeds high pressure oil nozzle 3 0.5-1.5mm suitable for reading; the lower end of high pressure oil nozzle 3 communicates with oil circuit 4; like this high pressure oil nozzle 3 just dress be soldered on the elastomeric plastics watts 2, and after high pressure oil fed, plastic layer 2 was in no high pressure oil infiltration with the junction plane of metal watt evil idea 1; plastics tiling 2 can be stripped from; guaranteed of the starting of high pressure oil lubrication system at unit; the full greasy property of thrust-bearing makes the elastomeric plastics tiling never wornout in operation and the shutdown overall process, and the high pressure oil nozzle is made with metallic material such as T2 hard copper rods.
