Lubricating oil temperature issues during turbine startup
Thread Content
May I ask if there are any specifications in standard or turbine codes regarding the lubricating oil temperature when starting a turbine? In which standard or specification is it specified? Thank you, **s.
There are no standard regulations; generally, it is controlled according to the turbine manual provided by the manufacturer
Before starting up the turbines in our factory, the oil temperature is required to be between 35 and 42 degrees. This requirement is quite strict; due to the high speed of the turbines, the viscosity of the oil is greatly affected by temperature. Therefore, to ensure a reliable lubrication through an oil film, it is necessary to maintain this oil temperature
They’re more or less the same; in my company, values between 33 and 45 are acceptable for conversion, though 37 would be ideal. Some clues can be found in API614, but it isn’t specified clearly; it’s related to the machine, and it’s definitely between 30 and 50. JBT6764 are the technical specifications for general industrial steam turbines; I hope it will be helpful to you.
The specifications do not provide clear guidelines; according to the manufacturer’s instructions, the temperature should be between 35°C and 42°C. However, it is best to keep the temperature at 37°C during operation, with 40°C being the upper limit
The steam can be used to heat the oil station until the oil temperature reaches 45 degrees
