EH oil system is to provide power oil to the main valve and speed regulating valve of the steam turbine, so as to make its action rapid, reliable and sensitive, and protect the safety of the steam turbine. The following is the relevant introduction about EH oil system: 1. Introduction: The EH oil system of steam turbine is the speed regulating oil system of steam turbine, also known as high pressure fire-resistant oil system, mainly because the speed regulating oil system and lubricating oil system of steam turbine are independent of each other, using high temperature resistant fire-resistant oil (EH oil), and adopting high oil pressure to control the main steam valve and speed regulating valve of steam turbine, so it is also called EH oil system of steam turbine. 2. Composition: EH oil supply system is mainly composed of EH oil tank, EH oil pump, inlet and outlet valve, filter screen, control block, overflow valve, accumulator, EH oil supply and return pipe, oil cooler and a set of self circulating oil filtration system and self circulating cooling system.
