Analysis of water content in turbine lubricating oil
Thread Content
I need help. Please analyze this: the turbine lubricating oil can lose half a barrel of water from its tank per shift. What should be done if water is present in the oil? Where could water get into the turbine? Do you have any solutions?
First, check the oil cooling system: after closing the inlet and outlet valves of the water circuit, open the drain valve of that circuit. Once all the water has been drained, if oil is present, it indicates that there is a leak in the oil cooling tubes, and it is necessary to switch to oil cooling. If the oil cooling system is working fine, it is necessary to check the steam seal and adjust the extraction pump to see the effect. A oil filter should be installed at the bottom of the oil tank to filter the oil and remove moisture; if no such filter is available, then the electric heater in the oil tank can be used to evaporate the moisture.
The second floor is the correct answer; if there’s a problem with the steam seal, it becomes more troublesome as the machine needs to be stopped in order to replace the seal.
Steam seals and oil coolers are prone to containing water
The second floor is the correct choice; removing the moisture there is rather difficult. A separate oil filter can be used for filtration while electric heating is activated, which yields better results than the electric heating built into the unit itself
If you don’t want to replace the steam seal, you can also make a vacuum tube and place it at the location of the steam seal to prevent water from entering the lubricant

The presence of water in the lubricating oil indicates that steam has entered the lubricating oil; the cause may be a poor seal. To resolve this issue, it is possible to check whether the dry gas seal system is functioning properly
The turbine should not have a dry gas seal; the pressure indicated by the dry gas seal is meant for use with compressors. Water in the lubricating oil can only be present in the oil cooler and at the steam seals. I think there’s probably no problem with the cooler, as it’s easy to check for issues; it’s more likely to be a problem with the steam seals. The efficiency of the steam seal extraction device is also low. Whether the oil tank heater is turned on or not makes little difference – if it is turned on, the temperature rises to just over 50 degrees. In my opinion, it’s not possible to remove the water from there. My opinion is to use a vacuum oil filter for continuous dehydration; of course, the heater of the oil filter must remain on at all times. The heaters and coolers available at the oil station are used to control the temperature of the lubricating oil. It’s important to conduct frequent analyses of the water content in the lubricating oil. Try not to shut down the system unless it’s absolutely necessary. I don’t know which factories are so stubborn as to shut down the system as soon as a problem is detected
