A Study on the Dynamic Characteristics of an Oil System for Turbocompressors (Header Pressure Control by a New-Type Oil Hydraulic Valve)

概要

An oil system is the equipment used to control the flow of hydraulic oil to the bearings and seals in process compressors and steam turbines. Conventional oil systems, in many cases, are controlled by pneumatically operated process control valves. It is generally difficult, however, to control the relatively rapid response of an oil hydraulic system by a pneumatically operated control system. A new type of control valve for header pressure control was therefore developed. The dynamic characteristics of the oil system using the new type of valve were examined theoretically and experimentally. The effect of parameter variation on the pressure response and stability of the control valve was clarified. The result was that the stable region of this system increased with an increase in the valve flow force.
