Hydraulic Video Series
Fundamentals of Hydraulics and Troubleshooting
This video provides an excellent visual introduction to hydraulic systems and many of the problems they can develop. Developed and produced in partnership with major hydraulic equipment manufacturers, Fundamentals of Hydraulics & Troubleshooting explains the fundamentals of hydraulic systems and demonstrates industry-accepted practices for diagnostics and troubleshooting.
Topics covered include:
 |
Safety procedures for working on hydraulic equipment
|
|
Reservoir design and construction
|
|
Hydraulic fluids
|
|
Pumps
|
|
Directional control valves |
|
Relief valves |
|
Cylinders |
|
Cavitation and aeration |
|
Common causes of slow cycle times |
|
Diagnostic testing |
Color animations are used to explain:
|
How hydraulic pumps create flow and resistance to flow creates pressure
|
|
Operating principles of external gear, internal gear, vane, axial piston and radial piston pumps
|
|
Function of open center, closed center and cylinder circuits
|
|
Importance of proper reservoir design
|
|
How suction strainers cause cavitation at the pump inlet
|
|
Operation of direct-acting and pilot-operated relief valves |
The following diagnostic tests are explained and demonstrated:
|
Direct pump test (pump flow test)
|
|
System "T" test (system load test)
|
|
Spool valve leakage test
|
|
Cylinder piston seal leakage test
