3Characteristics and cooling scheme of hydraulic station:

The key components of the hydraulic station are made in JapanNACHIInternal meshing high-pressure gear pump, servo valve adopts ItalianDLHZOThe servo valve and pressure follower valve use hydraulic components imported from the United States to improve the stability and long-term reliability of the hydraulic system. The oil source also adopts the latest pressure following technology, which means that the system pressure increases synchronously with the load, so that the system pressure does not have to maintain high pressure for a long time, which can generate excessive heat in the system. This technology makes the hydraulic source more energy-efficient, with energy-saving efficiency up to60%At the same time, minimize the heat generated by the hydraulic system.

The hydraulic source cooling adopts the built-in air cooling system of the equipment for cooling. Users can cool it as long as they turn on the power, without the need to connect cooling water.
