DIFFERENTIAL PRESSURE REGULATORS

摘要

RELIABLE CONTROL OF SEALING PRESSURE REDUCES TRIPPING, DOWNTIME AND RISK FOR TURBOMACHINERY SEALING OIL SYSTEMS. In large rotating equipment, such as compressors, turbines and pumps, pressurized oil is used in seals to prevent process fluid leaks and stop lubricating oil from gaining entry. In large turbogenerators, it is common to use sealing oil to minimize hydrogen coolant contamination, thereby reducing the risk of an explosion. Reliable sealing pressure control lowers these safety risks, as well as helping to avoid machine tripping and downtime.
