Recirculation System 

The recirculation system keeps the hydraulic oil at operating temperature while 
using the minimum amount of cooling water flow. The system also provides the 
necessary oil conditioning and filtration to maintain oil cleanliness.  The 
conditioning of the hydraulic oil includes cooling it, cleaning it, and together 
with the hydraulic tank, removing air bubbles entrained in the oil due to 
agitation and turbulent flow in the main pump circuit.   

10.1

 

Components 

The cooling and filtration system (recirculation system)

 

is equipped with the 

following: 

•

 

Recirculation pump

 (gear-type)–which receives oil from the oil tank 

•

 

Heat exchanger

 - cooling water is controlled by the water modulating valve 

•

 

Oil filter assembly

 - includes an indicator to show the filter element 

condition.   It also includes a bypass or relief valve, should the filter element 
become entirely clogged with dirt/contaminants.
