Chapter 6.1
(FLUID STORAGE AND CONDITIONING)
RESERVOIR
Other purpose :tada:
Remove Solid Particles
Release Air from Fluid
Remove Heat
Seperate Water from Fluid
Sizing of reservoir
Make allowance for dirt and chips
Hold all the oil that might drain
Maintain high oil level
Large surface to dissipate heat
Space to allow for thermal expansion
Reservoir size is three times the volume flow rate
Purpose : to hold the system fluid while currently used in the system
FILTERS AND STRAINERS
Contaminated hydraulic fluid reduce ability to:
Transfer Energy
Transfer Heat
Seal Clearances
Provide Lubrication
Purpose
Used to remove contaminants by trapping insoluble material contained in hydraulic fluid
Strainers : considered as coarse filters design to remove large particles
Filters : considered as fine filters that can remove small particles
Basic Types of Filtering Methods
Mechanical
Containing metal or cloth screen, capable remove relatively coarse particles
Absorbent
Using porous and permeable materials (wood pulp, paper, cellulose), capable remove very fine particles
Adsorbent
Using surface phenomenon where particles have tendency to cling to surface of filter (clay, chemically treated paper)
HEAT EXCHANGERS
Function
Used to maintain the operating temperatures of the fluid within specified limits
Heat-dissipation heat exchangers
Air cooled heat
Water cooled heat
Excessive temperature hastens oxidation of hydraulic oil. Promotes deterioration of seals and accelerates wear between fitting parts
Used to cool hydraulic fluid (removing heat), or to increase the tmperature of hydraulic fluid ( adding heat) when in cold climate
Sizing Of Heat Exchanger
Energy Loss = t(IHP - OHP)
