bearing seal and oil tank ventilation system

Stern tube Lubrication systems

Oil retention and exclusion of sea water necessitated the fitting of an external face type seal The stuffing box was retained in many early oil-lubricated stern tubes at the inboard end In oil-lubricated bearings the shaft does not require a full length protective bronze sleeve

Advanced Technology of Propeller Shaft Stern Tube Seal

oil lubricated stern tube bearing system is applied There are various kinds of seal systems used such as lip type or mechanical type for oil lubricated stern tubes The basic function is to prevent oil leakage from and seawater penetration into the stern tube The most popular oil lubricated seal is a lip type seal and an example is shown in

Fuel Tank Venting

Fuel Tank Venting Your tank has to breathe In order to breathe your tank must have a vent somewhere that will relieve both vacuum and pressure Gasoline expands in volume as it warms up and shrinks in volume as it cools down The fuel level of your tank changes throughout the day even if you are not driving it

DESIGN OPERATION AND MAINTENANCE CONSIDERATIONS

Lube oil will have a natural tendency to migrate along the shaft from the bearing to the barrier seal requiring the bearing cavity to be designed to minimize the exposure of the barrier seal to lube oil Flooded bearing drains place greater demands on barrier seals so it is also imperative to size and locate bearing cavity drain porting and

Centrifugal Compressor Wet Seals

• Seal oil degassing may vent 40 to 200 scf/minute System leads to lower emissions from degassing tank vent (more details on following slides) 4 Sour seal oil vapor recovery system on wet seals compressors much lower in capital cost requires short duration compressor

How do Seal Pots and Seal Support Systems Work?

A standard inner seal safely vents vapor to a recovery system so that zero emissions are achieved A pressurized external barrier fluid reservoir system supplies clean fluid to a pressurized dual mechanical seal with forced circulation Pressurized barrier fluid is used to lubricate both the inner and outer seal

Key considerations for dry gas seal performance

The seal panel the seal piping arrangements and the seal vent system details are critical for reliability performance safety and operation of dry gas seals in turbocompressor applications Compressed gas properties and conditions should also be carefully considered when specifying a dry gas seal and designing the seal system

GENERATOR SEAL OIL SYSTEM

in the hydrogen defoaming tank with the oil containing hydrogen The oil is then transferred to the main tank where the physically dissolved gasses are removed under vacuum (degassed oil) Pressurisation of the system is controlled by the cutting in of the AC- or DC seal oil pumps when oil over-pressure relative to

Stern bearing housing and arrangement of stern tube

A pump attached with a cooler continuously pumps oil into the bearings to maintain the required pressure In case the pump fails of the two header tanks under gravitational pressure provide the required oil with a back pressure to the bearing system Thus it is imperative that the level of hydraulic oil is well maintained in each header tank

Seal Oil System

Oct 11 2012The seal oil system prevents gas from leaking out of the compressor case Fig 8 46 is a schematic of a typical seal oil system working in combination with a buffer gas system These systems require auxiliary equipment such as pumps regulators filters and so on for proper operation The oil that flows across the outboard ring mixes with the bearing lube oil and returns to a lube oil tank
