List of Components Valve Fluid Hoses Pump Mot
or Cylinder Reservoir Filter Accumulator

• I can take any shape you want me to.
• I am simple enough that almost anyone could build
  me
• I can be high, low or placed almost any where
  have little or no affect on the work
• I can be invisible or at least you don't know
  where I may be
• I am the one component that you can do without.
• I give rest to a tired fluid

I am a Reservoir
3
Hydraulics

• Reservoirs and Coolers

4
Objectives

• 1. State the functions of a reservoirs.
• 2. List the parts of a common reservoir.
• 3. List several design features that promote the
  functions of the reservoir.
• 4. Draw the schematic symbols for a reservoir.

5
Functions of Reservoirs

• a. Hold fluid 1 purpose
• b. Where fluid can cool down
• c. Where air can separate from fluid
• d. Contaminates can be removed or settle

6
Secondary Functions

• a. Part of frame -- tractor
• b. Ballast side mount bush hog
• c. Mounting platform -- pump, filter or other
  components

7
Trick Question

• Does everything that is hydraulic need a
  reservoir? Why? Or Why Not?
• Hydrostatic systems __ yes _X_ no __ Maybe
• Ram type cylinders __ yes _X_ no _x_ Maybe

Design features of a Reservoir

• 1. Off floor
• 2. Heavy metal plate
• 3. Cupped (oval) bottom
• 4. Inside sealed with anti- rust
• 5. Has glass check instead of dip stick or remove
  cover
• 6. Screen in fill hole

12
Design features continued..

• 7. Higher flow rate larger breather needed
• 8. Air valve used on non vented systems
• 9. Baffle plate separate the incoming from
  out-going. Prevents turbulence, which allows
  foreign materials to settle, helps dissipate heat
  through walls
• 10. Lines - Pump inlet lines must be well below
  the fluid level, this keeps the fluid from air.

13
Design features continued..

• 11. Lines that end near the bottom need to be
  cut at 45 degree.
• 12. Size -- Rule of thumb 2-3 gallons for each
  gpm tank size in gallons pump gpm x 2 or 3
  need room for expansion of fluid system demand.
• Pump delivers 10 GMP what should be the reservoir
  size
• Answer 20-30 gallons
• 13. Heaters below fluid level 10 watts /cubic
  inch
• How many cubic inches in a gallon? 231
• What size heater for the 20 gal reservoir is
  needed
• 231 x 20 4620 or a 5000 watt heater
