Scraping and grinding of guide bearing bush and thrust bush of small hydraulic turbine is a key process in the installation and repair of small hydropower station. Most of the bearings of small horizontal hydraulic turbines have no spherical structure and thrust pads have no anti weight bolts. As...Read more »

According to China’s “rules for the preparation of hydraulic turbine model”, the model of hydraulic turbine is composed of three parts, and each part is separated by a short horizontal line “-”. The first part is composed of Chinese Pinyin letters and Arabic numerals...Read more »

Inexhaustible, inexhaustible, renewable 5. Control flooding 6. Provide irrigation water 7. Improve river navigation 8. The related proj...Read more »

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 »
