Introduction Hydroelectric generators generally have r. Rated current r, the unit of the hydraulic generator a r, refers to the maximum working line current of the generator during normal, continuous operation, the unit is A, kA, water flows through water

Hydrogenerator units generally have r

Yes. The rated current r, which the hydraulic generator set has r, refers to the maximum working line current of the generator during normal, continuous operation, in units of A and kA. As water flows through the turbine, the energy of the water is converted into mechanical energy. The energy, and the rotating shaft of the turbine drives the generator. The rotor converts mechanical energy into electrical energy and produces it. It is the main electrical equipment for generating electrical energy in hydroelectric power stations.

What is the specific content of inspection of hydraulic turbine before trial operation of hydraulic generator set? Will Zhongda Consulting answer the questions below?

1. The turbine wheel and all components have been installed and inspected and passed inspection. The construction files are complete. The space between the upper and lower sealing rings or the space betweenthe axial flow turbine. The runner blades and runner chamber have been checked and there is no debris left behind.

2. The vacuum cut-off valve has been installed and passed the leak test and action test under the design pressure.

3. The top cover drainage pump has been installed and passed inspection (manual) and the automatic operating circuits are normal. Artesian drainage holes are clear and unobstructed.

4. The main shaft working seal and maintenance seal have been installed and inspected and the maintenance seal has no leaks. Adjust the water pressure of the working joint to the value specified by the design.

5. The water guide bearing lubrication and cooling system was inspected and passed inspection. The oil level, temperature sensor and cooling water pressure have been debugged, and each value ofadjustment meets design requirements.

6. The water guide mechanism has been installed and inspected and is in a closed state, and the relay is locked and put in place. The maximum opening of the guide vane, tightness after closing and pressing stroke were verified to meet the design requirements. The shear pin shear signal and other guide vane protection devices have passed the inspection test.

7. All pressure gauges, flow meters, flow meters, swings, vibration sensors and various transmitters have been installed. The pipes are well connected and debris has been removed.

8. The waste water jet air supply device has been installed and closed. Assuming that the waste water will not flow back, the natural air supply valve to the turbine shaft should be opened.
