Who has turbine oil standards?
Thread Content
Does anyone know what grade the No. 22 turbine oil specified in SyB1201-61 currently corresponds to, or which standard this standard has been replaced by? Thank you all!
No. 22 should now correspond to 32. It used to have a kinematic viscosity of 50°C, but now it has a kinematic viscosity of 40.
3. Turbine oil standards and development In 1960, the domestic steam turbine oil (turbine oil) standard (SYB 1201-60) was formulated for the first time.； In 1978, the turbine oil standard was revised and SY1201-78 replaced the SYB 1201-60 standard. ； GB 2537-81 turbine oil standard was released in 1981 ； The SY 1230-83 anti-rust turbine oil standard was released in 1983. This is a transitional standard that is in line with international standards. ； In 1989, the international standard ISO8068-87 was adopted and L-TSA turbine oil GB111120-89 was formulated. * * Standard, which is the latest domestic specification standard with comprehensive performance and relatively advanced technical indicators.
