The PVH74(QI)C-RSM-1S-1X-C25-31 is a hydraulic pump designed specifically for the high-pressure fire-resistant oil system of steam turbines, highly praised for its efficient, reliable, and flexible performance. As one of the core components of the hydraulic system, the pump has demonstrated excellent application value in multiple fields.
Structure:
The structural design of the PVH74(QI)C-RSM-1S-1X-C25-31 pump is compact and exquisite. With a flexible casing, this pump adopts an open circuit, axial plunger design, and its saddle shaped cradle has steel backed polymer bearings. This design not only provides excellent rigid support, reduces deflection, but also evenly distributes bearing load, extending the service life of the pump.
As the core of the high-pressure fire-resistant oil system of the steam turbine, the PVH74(QI)C-RSM-1S-1X-C25-31 pump provides fast response speed to ensure reliable operation of the system under different flow and pressure conditions. Its open circuit design endows the pump with the ability to flexibly adapt to different hydraulic systems, and multiple control methods make it perform excellently under various working conditions.
Working Principle:
The working principle of the PVH74(QI)C-RSM-1S-1X-C25-31 pump is based on the axial plunger design and automatic adjustment of the pressure compensator. When the system flow rate changes, the pressure compensator will adjust the stroke of the plunger to maintain the system oil pressure at the set value. This design ensures efficient operation of the pump in high-pressure fire-resistant oil systems.
