Seal Installation

Airend Sealing System

1)Apply a thin coat of compressor fluid to the outer face of the seal wear sleeve and seal lip.

2)Cover the keyway in the compressor shaft with masking tape so there is no chance of damage occurring to the seal face during installation.

3)Apply Loctite® 515 or 518 to the gearbox seal adapter mounting flange. Use a roller to apply a uniform, thin coat on the flange. Remove any excess Loctite® around the fluid feed hole.

4)Install the shims in the same order as removed. Thickest shims should be facing the seal adapter. Thinnest shims should be in the middle of the shim stack.

5)Slide the proper seal installation sleeve against the wear sleeve with the taper toward the end of the input shaft. Lubricate the seal lips and installation sleeve with compressor fluid. Carefully slide the seal adapter with the new seal installed over the end of the rotor shaft and up against the adapter bore.

6)Align the fluid feed hole with the slot on the seal adapter and evenly draw the adapter into the bore, install the four retaining bolts and tighten to the specified torque. Remove the installation sleeve.

The airends have a redundant shaft seal arrangement that consists of three segments:

1)A primary set of seals on the dry side with a pressurized buffing air flow.

2)A sinuous seal with an air dam.

3)An atmospheric fluid drain on the bearing side.

The sealing system incorporates a redundant seal system to ensure no fluid enters the compressor chamber. The seal consists of multiple, floating carbon ring seals and a sinuous path to prevent bearing fluid from migrating into the compression chamber. In addition to the physical seals and a drain pocket, there is a positive flow of buffing air introduced in the floating carbon rings to create a pressure differential which sweeps fluid to the drain pocket. The buffing air for stage one is supplied from the interstage piping through a pressure regulator. The pressure regulator is factory set at 4-5 PSI. The pressure setting should be checked at every service interval and adjusted if necessary. Outlet of the buffing air is routed through collection filters. These filters collect the fluid vapors normally present in the buffing air drain. The filters should be drained occasionally. Collection levels and frequency of draining will vary depending on operating conditions. If a drastic change in the collection levels occur without a change in operating conditions, call the factory for service.

There is a smoke eliminator to remove and collect trace amounts of fluid vapor and return them to the gearcase. If the collection filter for the smoke eliminator requires frequent draining, replace the smoke eliminator.

NOTE

Do not restrict the air flow from the vents located at the outlet end of the package. Doing so may cause fluid leaks.
