    Describe the sequences of a positive displacement pump.

     

    Differentiate between fixed and variable displacement pumps.

     

    Classify and describe the three types of positive displacement pumps commonly employed in hydraulic systems.

     

    Describe how a variable displacement pump can vary flow rate.

     

    List the two main types of vane pumps

     

    Identify parts in an unbalanced vane pump and draw a diagram.

     

    Describe how an unbalanced vane pump executes the phases of a positive displacement pump.

     

    Describe how a variable displacement unbalanced vane pump works.

     

    Define eccentricity and concentricity. Identify which positions produce max/min flow rate.

     

    Describe the main disadvantage of unbalanced vane pumps and how balanced vane pumps solve this issue.

     

    Identify parts in balanced vane pump and draw a diagram.

     

    Describe how a balanced vane pump executes the phases of a positive displacement pump.

     

    Take apart a fixed displacement unbalanced vane pump. Identity internal components.

     

    Take apart a variable displacement unbalanced vane pump. Identity internal components. (NOT SHOWN IN LECTURE)

     

    Take apart a fixed displacement balanced vane pump. Identity internal components.

     

    Define the term cartridge. Identify advantages of cartridges when repairing vane pumps.
    Find the data sheet for a vane pump. Identify displacement, drive speed range, viscosity range, fluid cleanliness requirements, and other pertinent specifications. Explain flow rate as a function of pressure, flow rate as a function of drive speed, and other pertinent charts. (Vane Pump Data Sheet Parker T6C Balance Vane Pump Datasheet)
