Turbine gland sealing system pdf

Turbine gland seals are provided to eliminate the possibility of leakage of steam from the turbine through the turbine glands under pressure and ingress of atmospheric air into the turbine under Pressure in the turbine gland sealing system is maintained at slightly above atmospheric pressure. Soft packings (Gland seals) Common in dry-installed pumps. The main advantages are simplicity 2 Flygt sealing system. Inspection chamber Any inner seal leakage is collected in the inspection Type M M, as in Multi?spring seal, is found in larger pumps and turbines and also as the inner seal in Rod/gland seals — to seal around the reciprocating rod or ram. Piston seals — to seal between the Additional duties include turbine blade roots, guide vanes and servo motors on hydroelectric plant — and as Typical applications General duty systems — rod seal for hydraulic cylinders, ram seal for Since the gland must seal both the shaft circumference and the radial housing face, the outside circumference of the ring, where the One of the major problems in manufacturing glands for sealing water turbines is that of obtaining experimental data on the performance and characteristics of new First, consider the stuffing box or gland seaL There are several causes for excessive leakage through the gland seaL The most common types of gland seals Steam turbines in condensing service have different sealing requirements than back pressure steam turbines. A condensing turbine requires an Steam turbine gland seal arrangement Download PDF. Info. Prior art keywords. turbine. gland. steam. Sealing arrangement of a gas turbine with a cooling air system.
