Measures to prevent oil steam turbine broken tile burning and bearing damage

Prevent damage of turbine oil broken tile burning and bush measures - 2021 01 - 02 a, to prevent the steam turbine oil burning safety technical measures of 1, strengthen the monitoring of oil temperature, oil pressure adjustment, closely monitor the bearing metal temperature, abnormal should be timely find the reasons and to eliminate. 2, spare reliable oil system equipment, and strict test on a regular basis. The running of pump or cold oil smooth stop switch should be cautious, fight off oil tile burning. 3, oil purification plant operation is normal, oily should comply with the standards. 4, to prevent the steam turbine, shaft bending, the water bearing vibration and damage on flow passage. 5, steam turbine generator rotor should be reliable grounding. 6, should be carefully before start setting according to design requirements of ac, dc oil pump interlock fixed value, check the wiring is correct. 2, the primary technical measures to prevent damage of the steam turbine bearing 1, oil system of each valve should be sign, oil system of switching work according to regulations. 2, lubricating oil system valve stem or scale. 3, oil pump equipment regularly test, oil pressure should be from the most distant way in the cold oil machine with the center line of the steam turbine bearing shell shall prevail. Dc oil pump power fuse appropriate chooses a higher level. 4, the constant speed of turbine, stop the pump run time should pay attention to the change of oil pressure. 5, fuel tank oil level should comply with the rules. 6, lubricating oil pressure should comply with the design value. 7, before the downtime should test lubricating oil pump rear can normal downtime. 8, strictly control the oil temperature. 9, steam turbine as a bearing fault oil smoke or bearing return oil temperature suddenly rise to emergency stop value should be emergency stop. 10, any steam turbine bearing temperature jumped to emergency stop value should be emergency stop. （ Source: coal-fired power plants with running knowledge)
