Discussion and analysis on problems of lube oil cooler and the oil cooler three way valve of a thermal power unit

Abstract

Lube oil cooler is an important heat exchange equipment to provide suitable oil temperature for steam turbine unit. Its reliability is directly related to the normal operation of the unit. Combined with the system commissioning work, this paper finds out the problems existing in the lube oil cooler body and the oil cooler three way valve, and puts forward several improvement and optimization schemes, so as to improve the operation status of the equipment, improve the reliability of the system, and also facilitate the maintenance of the equipment, which provides a design reference for ensuring the safe and economic operation of the unit.
