Hydropower Knowledge

Hydrogenerators can be divided into vertical and horizontal types according to their axis positions. Large and medium-sized units generally adopt vertical layout, and horizontal layout is usually used for small and tubular units. Vertical hydro-generators are divided into two types: suspension ty...Read more »

If the hydro generator ball valve wants to have a long service life and maintenance free period, it needs to rely on the following factors: Normal working conditions, maintaining harmonious temperature / pressure ratio and reasonable corrosion data. When the ball valve is closed, there is still p...Read more »

1.Types and functional characteristics of generator A generator is a device that generates electricity when subjected to mechanical power. In this conversion process, mechanical power comes from a variety of other forms of energy, such as wind energy, water energy, heat energy, solar energy and s...Read more »

The hydro-generator is composed of rotor, stator, frame, thrust bearing, guide bearing, cooler, brake and other main components (see picture). The stator is mainly composed of a base, an iron core, and windings. The stator core is made of cold-rolled silicon steel sheets, which can be made into a...Read more »

There are many types of hydroelectric generators. Today, I will introduce the axial flow hydroelectric generators in detail. The application of axial flow turbine generators in recent years is mainly the development of high head and large size. Domestic axial-flow turbines are developing rapidly....Read more »

Progression, referring to this, you may think of the progression of obtaining professional certificates, such as CET-4 and CET-6. In the motor, the motor also has stages. The series here does not refer to the height of the motor, but to the synchronous speed of the motor. Let’s take level 4...Read more »

1、 Division of capacity and grade of hydro generator At present, there is no unified standard for the classification of capacity and speed of hydro generator in the world. According to China’s situation, its capacity and speed can be roughly divided according to the following table: Classi...Read more »

1. Before maintenance, the size of the site for the disassembled parts shall be arranged in advance, and sufficient bearing capacity shall be considered, especially the placement of rotor, upper frame and lower frame in overhaul or extended overhaul. 2. All parts placed on the terrazzo ground sha...Read more »

China current power generation forms mainly include the following. (1) Thermal power generation. A thermal power plant is a factory that uses coal, oil, and natural gas as fuels to produce electricity. Its basic production process is: fuel combustion turns the water in the boiler into steam, and ...Read more »

The U.S. Energy Information Administration (EIA) recently released a report stating that since the summer of this year, extreme dry weather has swept the United States, causing hydropower generation in many parts of the country to decline for several consecutive months. There is a shortage of ele...Read more »
