46.2.1 Hydraulic Pumps/Systems

 

· A geared hydraulic pump is pictured below. Other types use vanes and pistons.

 

 

· Hydraulic systems use pumps to cause fluid flow. Resistance to that flow will allow pressure to build up. This fluid is directed through a systems with,

  1. - oil filters to clean
  2. - heat exchangers to cool oil
  3. - gages to monitor pressure
  4. - relief valves to release fluid when a maximum pressure is passed
  5. - a reservoir to collect uncompressed fluid
  6. - check and flow valves

 

· The hydraulic system drives pistons and other hydraulic actuators.
