According to clause 6.3 of document GB/T7894-2009 "Basic technical conditions for hydrogenerators", when the hydrogenerator operates under normal working conditions, the maximum temperature measured using the method of built-in thermometer should not exceed:
Guide bearing regula alloy tile 75℃
Guide bearing plastic tile body 55℃
So if the ambient temperature is 20℃, the temperature increases are 55K and 35K.
According to the different positions of the thrust bearings, what types of hydraulic generators can be divided into?
The bearings of the hydraulic generator are cylindrical roller bearings on one side and deep rolls on the other. The side facing the coupling (back wheel) is cylindrical. The model number should be N326EM. I hope my answer can help you!

According to the different positions of the thrust bearings, the turbine generators to water can be divided into two types: hanging type and umbrella type.
The generator with the thrust bearing located above the device is called a suspension generator, which is suitable for speeds above 100 rpm. The advantages are low thrust bearing loss, easy installation and more stable operation; The downside is that the taller the unit, the more steel is used.
The generator with the stopper located below the device is called an umbrella generator. The generator without top guide is called full umbrella generator. The generator with top guide is called umbrella generator. speeds below 150 rpm, the advantage is that theunit height is low, which can reduce the height of the factory building and save steel; the disadvantage is that the stop has a significant loss and is impractical to install and inspect; , and maintain.
