6.4.5 Additional Recommended Features
The following features are not essential, but are recommended as
measures which will help to maximize hydraulic system reliability,
efficiency and life.
• Magnetic drain plug(s) trap ferrous particles and should
be easily accessed for cleaning.
• A temperature gauge, either separate or built into the
sight-glass, allows operator to read reservoir oil
temperature.
• A strainer in the filler neck keeps large contaminants out
of the reservoir during oil addition.
• A return line flow diffuser mounts to end of return line
drop tube and reduces the oil velocity before the oil
emerges into the main interior volume of the reservoir;
this is important on relatively small reservoirs (less than
about 1 gallon per GPM) where severe foaming and
aeration can occur if return line flow is not slowed prior to
tank entry.
• A reservoir heater for preheating the hydraulic oil prior to
startup in extreme cold climate conditions.
