Knowledge

Therefore, in actual design work, designers not only need to have solid professional knowledge, but also combine their own work experience

The consequence of the steam turbine cavitation is that the noise, vibration and efficiency of the turbine are sharply reduced,

Decreased output Under the condition that the head is unchanged, the guide vane opening pointer has reached the no-load opening,

The power plants (stations) in the power system include thermal power plants, Hydro Power Plants, and geothermal,

During the operation of the Hydro Power Plant, radial centrifugal force will be generated due to the static imbalance of the runner.

Insufficient power of the turbine means that the power of the turbine cannot reach the guaranteed power under the running head.

The common purpose of preventive and restorative maintenance is to identify the causes of damage and wear and eliminate them.

The main inspection items of the generator are as follows: first check whether the generator has abnormal sound,

In addition, by observing whether the generator excitation voltage, excitation current and generator stator current are normal,

The normal operation of the hydroelectric generating unit is very important for the hydropower station.

Set up an isolation protection net in the construction area of the prototype unit to isolate the maintenance area from the operating equipment.

The following is an overview of which state quantities are related to various faults. Most fault occurrence pairs will be accompanied by changes in certain state quantities.
