In　the　traditional　seawater　hydraulic　piston　pumps,　the　inherent　structure　of　the　slippers　made　it　susceptible　to　problems　such　as　eccentric　wear　and　slipper　burning.　A　new　integrated　slipper　was　proposed　to　fundamentally　eliminate　the　overturning　problem　of　slippers　caused　by　centrifugal　forces　and　to　reduce　the　lateral　force　on　the　pistons.　The　lubrication　mathematical　model　of　the　integrated　slipper/swashplate　interface　was　established,　and　the　influences　of　temperature　and　working　condition　parameters　on　the　lubrication　and　energy　consumption　characteristics　were　analyzed.　The　results　show　that　with　the　increase　of　medium　temperature,　the　dynamic　pressure　effects　of　integrated　slipper　decreases,　the　water　film　thickness　decreases,　resulting　in　the　decrease　of　leakage.　And　the　viscosity　decreases　with　the　increase　of　temperature,　the　friction　forces　on　the　integrated　slipper　decrease,　and　the　viscous　friction　power　losses　decrease.　With　the　increase　of　working　pressure,　the　water　film　thickness　increases,　the　leakage　increases,　and　on　the　contrary,　the　viscous　friction　power　losses　decrease.　With　the　increase　of　the　shaft　speed,　the　volumetric　power　losses　and　viscous　friction　power　losses　of　the　integrated　slipper/swashplate　interface　increase.　©　2022　China　Mechanical　Engineering　Magazine　Office.　All　rights　reserved.
