叶片泵/变量叶片泵PVD series

迪普马公司于1952年成立于意大利北部的布斯托阿西齐奥，早期致力于开发具有创新意义的仿形系统：液压仿形单元。在那个年代，这些设备具有革命性意义，并对机床行业的革新做出了重大贡献。在上世纪70年代初，公司开始生产和销售液压元件和系统，在工业领域得到迅速认可。即使是仿形单元配套的小型液压系统也变得越来越复杂，这使得公司在很长一段时间内处于液压系统设计市场的*位置。 在过去的二十年中，迪普马液压采取了产品样本的革新策略，专注于技术创新和性能优化，这使得公司始终保持在意大利和*市场的竞争力。 迪普马液压是液压市场中的真正选择。全面的产品系列，系统部门设计的解决方案，连同*化的销售和服务网络，为客户提供了真正具有竞争力的优势。多年以来，作为市场中勇敢和著名的参与者，迪普马液压总部新址位于帕拉比亚戈（临近米兰），工作面积约为8000m?，有员工120名。2013年，迪普马液压销售额为3000万欧元，并且年元件产能达到一百万件。在其“客户、质量、服务”的价值观激励下，迪普马液压正前行在成长的道路上。 叶片泵 DFP - 定量叶片泵 The DFP pumps are fixed displacement vane pumps made in four different sizes, each size having five different nominal displacement. They are available with one pumping element (single pump) or with double pumping element (double pump). - The pumping group is composed of a cartridge type compact element that contains the rotor, the vanes, the cam ring and the head disks. The cartridge is easily removable without the need to disconnect the pump from the hydraulic circuit, thus simplifying the maintenance operations. - The special elliptical profile of the cam ring, with double suction and delivery chambers one against the other, eliminates the radial thrusts on the rotor, decisively reducing wear of the pump. In addition, the use of a 12-vane rotor reduces the delivery pressure pulsations, suppressing the vibrations and noise level of the pump. PVD - 变量叶片泵带直动式调节器 注意：泵PVD9、13、17和22，30系列，不再提供。 对于较小的规格，只提供泵PVD 25，31系列。 从28至145的其他规格保持30系列。 PVE - 变量叶片泵带直动式压力调节器 叶片泵新成员PVE，序列号30。该泵为变量叶片泵带直动式压力调节器。 可提供四种规格，*大排量从6,6到22,2 cm3/rev，压力调节器*大设定值为35 bar和70 bar (标准)。 PVA - 变量叶片泵带先导式调节器 The PVA pumps are variable displacement vane pumps with piloted type hydraulic pressure compensator. - They permit instantaneous adjustment of the flow rate according to the circuit requirements.The consequence is that energy consumption is reduced and adequate in every cycle phase. - The pumping group is complete with hydrostatic axial compensation distribution plates that improve the volumetric efficiency and reduce wear of the components. - The pressure compensator operates with the principle of keeping the cam ring of the pumping group in the eccentric position with use of a piston controlled hydraulically by a pressure pilot stage. - When the delivery pressure equals the pressure corresponding to the pilot stage setting, the cam ring is moved toward the center adjusting the flow rate to the plant requirements. - In zero flow demand conditions, the pump delivers oil only to compensate any possible bleedings and pilotings, keeping the circuit pressure constant. - The compensator response times are very restrained and such as to allow elimination of the pressure relief valve. - Also available are the versions with maximum flow adjustment PVA***Q and with the device for selection of two independent pressure values with solenoid valve PVA***M
