Hydraulic Pressure vs. Flow: Understanding the Difference
The higher the flow rate, the faster the actuator will move. If you trace the flow from the pump, you reach a “T” in the line. Whenever you follow the flow on a schematic and arrive at a line split, you must track the flow in both directions to determine the path of least resistance. Hydraulic fluid always takes the path of least resistance. I
That is why Parker hoses carry different temperature ratings for different fluids. For example, 811HT hose has a temperature range of -40°F to +257°F for petroleum-based hydraulic fluids. For water, water/glycol, and water/oil emulsion hydraulic fluids the maximum working temperature drops to +185°F and for air, the rating drops to +158°F.

The hydraulic reservoir stores non-pressurized hydraulic fluid, typically hydraulic oil. This fluid is the lifeblood of the hydraulic system. The hydraulic oil also travels through a filter that collects impurities. Hydraulic pumps transfer the fluid from the reservoir to the hydraulic system.

Top Things To Know About Hydraulic Oil Viscosity
Hydraulic system uses different oil types for performing functions like lubrication, heat transfer, power transmission, and sealing. For achieving a properly working hydraulic system, the manufacturer or designer must need to consider various hydraulic fluid properties like viscosity, compressibility, demulsibility, fire resistance, etc.. Among all these, hydraulic oil viscosity is necessary
