According to our problem in power plant, we have temperature of EH (Electro Hydraulic) oil increased which is use Turbofluid 46 XC Chemtura.
We already checked the cooler and another valve that should be open or closed for the operation and all are based on Standard operating Procedure. Before this problem we used Turbofluid 46 SJ, differences are kinematic viscosity about 38.17cSt for XC and 46cSt for SJ.
My question ;
1. Is the lower kinematic viscocity made the temperature of oil incresed? we used piston pump for the hydraulic pump.
2. Is the increasing temperature made kinematic viscocity getting lower?? because now on the viscocity is 35 cSt (40 deg C)
I hope i can get any information about this problem.
