Packing cases and oil wiper glands are vital to keeping your compressors running efficiently. Hi-Tech Compressor's reconditioning service restores packing and oil wiper glands to factory specs through our rigorous quality-controlled processes and ensures compliance with current API guidelines.
Developing a Plan for Reconditioning
Our technicians thoroughly inspect and document all incoming cases, wiper glands and their rings. By carefully measuring key dimensions and examining assemblies with a trained eye, our staff will recommend a specific reconditioning protocol to resolve problems, improve performance and extend service life.
Before disassembly, we mark all cups to ensure accurate reassembly. We then thoroughly clean, measure and inspect all components, and replace any worn items that are not repairable. Our technicians precisely machine cups to ensure correct depths for seal rings, 'O' rings, and gasket grooves while adhering to specific tolerances for proper clearances.
Obsessive Attention to Detail
To ensure a tight gas seal between the packing and piston rod, as well as between cups, we machine surfaces to precise perpendicularity and parallelism. Sealing surfaces are ground and lapped to assure proper mating of the packing to the cup and to enable a tight cup-to-cup seal.
Finally, our technicians carefully reassemble cases with new packing, gaskets, o-rings and other parts as needed. One item which we pay particular attention to is the often-overlooked nose gasket.
The nose gasket is always replaced, and care is taken during handling and packaging that no damage occurs to this most vital component. We pressure test the packing case assemblies, including coolant passages if cooled cases, as well as test all lube, vent, and purge passages for free flow. All final inspection dimensions are recorded at this time.
Packaging includes VCI (anti-rust) packaging, bagging, boxing, and complete labeling with customer part number, P.O. number and any information requested by the customer. With a quick turnaround and quality execution, Hi-Tech Compressor will recondition your packing cases and oil wiper glands to deliver years of trouble-free service.
