The function of the vertical guide bearing 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 range of specified values.
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.
