  • Manage the Leakage or Manage the Machine

    On the surface, fluid leakage is a nuisance because the machines that leak need constant monitoring and top-ups to maintain the ideal level of lubricant to operate properly. Unfortunately, as we investigate leakage further, we realize that leakage can be a significant problem on many levels. Safety is a major concern when oil leakage is a factor.

    Preventing Leakage from ComponentsReducing The Potential For LeakageMaintaining Zero LeakageZero Leakage at What Cost?Benefits of Component IntegrationProgress in Leakage Reduction*Finding a component that promises leak-free performance poses no great challenge. All major component manufacturers offer products that meet SAE and ISO standards for reduced leakage. However, finding components that all deliver leak-free performance for an an entire machine becomes a tall order. This is because a fitting, hose, pump, valve, or cylinder may operate leak free for one application, but leak on another. Not surprisingly, then, most designers probably agree that achieving zero leakage throughout a machine involves a lot of trial and error. Sometimes, one component may not leak on one machine, but an identical component may leak when used in a different area of the same machine. Case in point: a cylinder that actuates the first articulating member of an excavatorarm may not leak, but an identical cylinder (at the other end of the arm) that pivots the bucket may leak. The difference is, the cylinder pivoting the bucket may undergo severe pressure spikes from shock loadi...

    Dec 17, 2011 · Inside diameter (ID) leakage occurs along the interface between the packing and the rotating shaft. This leakage serves to cool and lubricate the dynamic surface and is necessary for most braided pump packing applications. Outside diameter (OD) leakage exists when the liquid runs along the interface between the packing and the stuffing box bore. While it will have some cooling effect on the packing, it is unnecessary.
