【Q&A Question 053】February 22, 2018: Briefly explain what function the accumulator in the compressor lubrication system serves One of the functions of the lubricating oil system is to supply control oil to the turbine speed control system. The amount of control oil required is not large, but the oil pressure must remain stable. Two bladder-type accumulators are installed behind the filter; these bladders are filled with nitrogen at a pressure of 4.5 kilograms per square centimeter. The interior of the containers serves as a space for storing oil. The pressure inside the bladders is lower than that of the oil, keeping them in a compressed state. The role of these accumulators is to maintain a stable control oil pressure. When the main oil pump stops operating and the auxiliary pump starts, or when there is a change in the filter or cooler, the oil pressure drops. At such times, the rubber bladders expand immediately due to the pressure of the nitrogen, thereby maintaining a stable control oil pressure and preventing fluctuations in it.

(1) The accumulator serves to stabilize the oil pressure in the oil circuit. (2) At the moment when the main oil pump fails and the auxiliary oil pump starts, it also serves an emergency function to prevent a drop in oil pressure that could lead to shutdown via interlock action.
In the event of a failure in the oil system and a lack of oil, the oil in the accumulator can prevent the rotating components of the unit from being damaged for a certain period of time.
1 The accumulator serves to stabilize the oil pressure in the oil circuit. 2 At the moment when the main oil pump fails and the auxiliary oil pump starts, it also serves as a backup mechanism to prevent a drop in oil pressure that could lead to shutdown via interlock action.
The accumulator serves to stabilize the oil pressure in the oil circuit, preventing sharp changes in pressure under abnormal conditions
To serve as an emergency power source; to compensate for leaks and maintain constant pressure.
The main function of the accumulator is to stabilize the control oil pressure. When the main oil pump stops operating and the auxiliary pump starts, or when the filter or cooler is changed, the oil pressure drops. At such times, the rubber bladder expands due to the pressure of the nitrogen gas stored within it, thereby maintaining a stable control oil pressure and preventing fluctuations in it.
