Фиксированный displacement vane pumps PVV

Description Frame size 1, 2, 4, 5 Size 18 … 193 Component series 1X Maximum operating pressure 210 bar Maximum displacement 193.4 cm³ Maximum flow 285 l/min Features Fixed displacement Long bearing life through hydraulic relief of the shaft Low wear due to hydraulically unloaded vanes Low operating noise Easy to service due to exchangable pump cartridges Good efficiency Position of the pressure ports can be chosen Drive direction of rotation clockwise or counterclockwise Drive shaft optionally cylinderical or splined Double pump Very compact build Position of the pressure ports can be chosen separately Product description Hydraulic pumps of type PVV are vane pumps with constant displacement. The rotor (2) running in a stator ring (3) is located on the tooth profile of the drive shaft (1). The slots of the rotor accommodate the vanes (4) which are pressed against the internal surfaces of the stator ring by the centrifugal force upon rotation of the rotor. The displacer chambers are laterally sealed by the control plates (5). Due to the double-eccentric design of the stator ring, there are in each case two pressure chambers opposite of two suction chambers, which provides for hydraulic unloading of the shaft. So it only has to transmit the torque. The vanes are partially unloaded upon passage through the suction range. This unloading has a wear-reducing effect and ensures high efficiency. By simply removing the cover (6), the pump insert (consisting of rotor, vane, stator ring and control plates) can be removed without the need of removing the housing (7) from the pump carrier. This allows for fast maintenance and repair of the pump. Double pumps are formed by installing two pump installation kits on one joint shaft. The oil inlet is realized by one joint suction port in the central housing (10). The oil outlet is realized separately by both pump installation kits. For the front pump installation kit, the pressure port is located in the flange housing, for the back pump installation kit in the cover. The larger pump installation kit is always located on the flange housing side. Pump installation kits of the same frame size cannot be used as double pumps.
