    摘要： The present invention discloses a water-lubricated high-pressure pump using rolling support which relates the field of high-pressure water pump technologies, including a driving mechanism, a shell, a rolling bearing, an isolation structure, and at least one plunger and a plunger chamber. The driving mechanism includes a main shaft and at least one eccentric structure, and the main shaft is on at least one side thereof rotationally connected to the shell through the rolling bearing. The at least one eccentric structure is located in a first inner chamber of the shell, and the first inner chamber is configured for filling with water or aqueous solution. The rolling bearing is located in a second inner chamber of the shell, and the isolation structure is configured to seal the water or the aqueous solution inside the shell to prevent the water or the aqueous solution from entering into the second inner chamber. When the at least one eccentric structure is rotated, the at least one eccentric structure pushes the at least one plunger to move in the plunger chamber to realize pressurization of the water or the aqueous solution. The driving mechanism of the present invention does not use lubricating oil, and the main shaft support structure adopts a traditional rolling bearing, thus avoiding a hydrostatic pressure support and having a simple structure.

    摘要： Um bei einem Kolbenkompressor (1) eine Überschmierung der Zylinder (2) zu vermeiden und die Schmiermittelmenge auf ein für den Betrieb erforderliches Maß zu reduzieren, wird gemäß der Erfindung ein Schmiersystem mit einer Schmiersystem-Steuerungseinheit (14) bereitgestellt, in dem zumindest ein Schmiermittelsensor (15) zur Erfassung einer für eine Schmierfilmdicke eines Schmierfilms (11) an der Zylinderlauffläche des Zylinders (2) repräsentativen Schmierfilm-Messgröße (S) vorgesehen ist, wobei die Schmiersystem-Steuerungseinheit (14) dazu ausgebildet ist, das Schmiersystem im Betrieb des Kolbenkompressors (1) zumindest einmal in einem vorgegebenen Kalibrierbetriebsmodus zu betreiben und anhand der während der Durchführung des Kalibrierbetriebsmodus erfassten Schmierfilm-Messgröße (S) einen Schmierfilmzustandswert (SZ) zu ermitteln und dass die Schmiersystem-Steuerungseinheit (14) dazu ausgebildet ist, nach Beendigung des Kalibrierbetriebsmodus im Betrieb des Kolbenkompressors (1) die einzubringende Schmiermittelmenge in Abhängigkeit des ermittelten Schmierfilmzustandswerts (SZ) zu steuern.

    摘要： A lubrication additive recovery system is provided for use with a vapor compression system. The vapor compression system includes a compressor having a bearing, a condenser and an evaporator. The lubrication additive recovery system includes a lubrication ring formed to define first and second through-holes, a first system by which a portion of a required supply of lubrication is drawn from the condenser and provided to the bearing through the first through-holes and a second system by which a remainder of the required supply of lubrication is recovered from the evaporator and provided along with compressor discharge gas to the bearing through the second through-holes.
