Hydraulic power units are used in a wide variety of applications including oilfield, watercraft, towing, mining, agriculture, forestry, construction, drilling, etc. The Hydraulic power units are also referred to as Pumps. Hydraulic systems are commonly powered by a variable speed electric motor. It utilises three major components – accumulators, power train, and the hydraulic shaft.

In a Hydraulic Power Unit,like the ones from https://www.hydraproducts.co.uk/Hydraulic-Power-Units, a pump acts as a dynamic force which transfers both fluids from their source to a storage reservoir, and the fluids from storage to the hydraulic system. The gear drive system of Hydraulic power units is an effective and economical method of transferring fluids from one place to another. The gear train in a power train moves the fluid via shafts that are connected to accumulators in the power unit. As the fluid moves through the accumulator, hydraulic pressure increases. When the fluid moves to the hydraulic system, hydraulic pressure decreases.

Accumulator And Hydraulic System: When a hydraulic power unit starts working, the gear train pumps hydraulic fluid from a reservoir to an accumulator, which holds the fluid until it reaches a predetermined level. Here the predetermined level is determined by the amount of hydraulic systems pressure. When the hydraulic system reaches the predetermined level, a second pump starts the process over again. This process is repeated until there is no more hydraulic pressure in the accumulator or the predetermined level is reached. The accumulator is designed to hold a specific amount of fluid, depending on the amount of hydraulic systems pressure, and once the fluid reaches this level, it will be automatically pumped out to a discharge location.
