Bearing simulation test bed for vertical shaft type pumping and storing hydropower unit

Abstract

The invention provides a bearing simulation test bed for a vertical shaft type pumping and storing hydropower unit. The bearing simulation test bed for the vertical shaft type pumping and storing hydropower unit is characterized by comprising a rotary shafting (104), an upper test bed rack (101), a lower test bed rack (103), a test bed water guiding rack (105), a test bed stabilizing box body (106) and a test bed loading device (102), wherein the upper test bed rack (101), the lower test bed rack (103), the test bed water guiding rack (105) and the test bed stabilizing box body (106) are connected together in sequence from top to bottom in a spaced mode through 12 long bolts; an upward guiding thrust bearing (1) of the rotary shafting is connected with the upper test bed rack, a downward guiding and loading bearing is connected with the lower test bed rack, a water guiding bearing (7) is connected with the test bed water guiding rack, and a turning wheel (9) is connected with a variable-frequency motor which is fixed to the test bed stabilizing box body. By means of the bearing simulation test bed for the vertical shaft type pumping and storing hydropower unit, a simple simulation object convenient to use is provided for the study of the bearing bush operational mechanism and the abrasion prediction of the pumping and storing unit under a deep pitch peak working condition.

Description

technical field [0001] The invention relates to a simulation test device, in particular to a device for conducting simulation research on the shaft system / bearing operation mechanism of a vertical shaft pumped storage hydraulic unit, more specifically a vertical shaft unit for bearing pad oil lubrication It is a simulation test device for bearing operation mechanism research / bearing pad wear prediction research and simulation of partial fault operation of the shaft system. Background technique [0002] Pumped-storage hydraulic units have high water head and high speed, and are mostly used for peak regulation and phase regulation. Therefore, the operation mode is complex and there are many working conditions. The operating environment of the unit bearing bush is harsh. The tiles and guide tiles are very easy to wear and tear, and even tile burning occurs from time to time. One of the best ways to study this to avoid such phenomena is to conduct simulation studies. However, ...
