In September 2018, the temperature fluctuation of high-speed bearing of high pressure and low pressure expander increased to 116℃ while driving, and the unit jumped out of the train due to high temperature. After the replacement of oil, the temperature is controlled between 80-90℃, and the operation of a month or so, the bearing temperature has repeatedly fluctuated and increased, almost jumping value.

 

 

 

l Device name: polyethylene device

 

Unit name: D-91FE

 

Fix the problem: Remove the paint film

 

 

 

 

Tank capacity: 20m³

 

Oil type: 46# turbine oil

 

Oil use time: one year

 

 

 

 

Oil cleaning model No. : WVD-II varnish removal oil purifier

 

Operation time: December 2018 till now

 

 

 

 

Operation of the unit: the fluctuation of bearing temperature increases, and the fluctuation increases after the injection of a foreign brand of dissolved oil of about 300 liters. After each wave peak, the temperature drops, and then rises interactively, and the machine jumps repeatedly, resulting in the normal operation of the unit.

 

 

 

 

Operation of the unit: the phenomenon of temperature fluctuation and rise is relieved less than 24 hours after the equipment is put into use, and the temperature drops to about 85℃ less than one month after use.
