The conduction level on the turbogenerator should be kept below 0.3%, which is a qualified standard. According to the relevant information query, keeping the conduction level low can effectively reduce the loss of the hydrogenerator. Excessive conductivity level will increase the loss of the hydrogenerator, thereby reducing power generation efficiency and power output.
What is the function of the guide bearing of the vertical turbine generator?
Generally, the hydraulic turbine generator unit undergoes a thorough overhaul every 3 to 5 years, date at which the generator will be broken down. Check if the guide bearing is worn. If wear is significant, it can be repaired and polished before continued use. If it is damaged following an accident, it will need to be replaced. The summary is this: as long as it doesn't burn out, you can continue to use it.
The function of the guide bearingThe vertical of the turbine generator is to bear the radial mechanical unbalanced force and the electromagnetic unbalanced force of the rotating part of the unit, so that the axis of the unit oscillates within the specified value range.
The main signs of a guide bearing with good performance are:
(1) Sufficient working oil film thickness can be formed;
(2) The tile temperature should be within the allowable range, generally around 50°C;
(3) The circulating oil circuit is smooth and the cooling effect is good;
(4) The oil level in the oil tank and the bearing clearance meet the design requirements;
(5) The sealing structure is reasonable and does not shed oil
(6) The structure is simple; and easy to install and repair.
