Turbo Expander Seal Gas System. The Oil Seals may be used on applications where Dry Gas Seals are too sensitive for the operating conditions. Lube oil system and that there is no high speed rotating shaft seal needed to prevent leakage of the process gas or oil to the atmos-phere. Dry Gas Seals allow the lowest seal gas consumptions but require very high gas cleanliness. Dry Gas Seals.
In applications where there must be a high speed rotating shaft seal such as expander generator systems that do not have the generator rotor immersed in the process fluid then the shaft seal is. High pressure moderately cold gas flows into the Expander section of the Turboexpander. Single dual or tandem. Système de gaz de barrage pour turbodétendeur. Patented automatic thrust balancing system Our system allows the unit to reliably handle high thrust loads associated with high-pressure applications including at start-up shut-down and process upset conditions. Dry gas seals are also available.
After the oil has finished its work in the bearings it travels along the shaft until it reaches the hub where the spinning oil thrower literally throws the oil outwards by centrifugal force and it meets the inside face of the center housing where it drops down under gravity to be collected by the oil drain and.
A turbo-expander or expansion turbine is a radial in-flow or centrifugal turbine capable of efficient extraction of energy from any high-pressure gas being expanded through it. The expansion valve is adiabatic as well as a turbine and taking the work out of the expansion makes it isentropic. The device has a shaft carried in a housing on bearings with a compressor wheel on one side and an expander wheel on the other side. Dry gas seals are also available. The Oil Seals may be used on applications where Dry Gas Seals are too sensitive for the operating conditions. They can be proposed in several configu-rations.
