What is Reservoir | Definition, Importance, Construction
Reservoir is a tank which store the hydraulic oil for recirculation through the hydraulic system.
Importance of reservoir
B) Cooling of oil :- It acts as a cooling device for dissipation of heat in the oil through large surface area of the tank.
C) Separation of oil :- The dirt, dust wear particles settled down in the reservoir.
D) Structural support :- It acts as a base for pump-motor assembly, relief valve etc.
Construction of Reservoir
It consists of
A) Oil level indicator :- It is the level indicator to show the quantity of oil available in the tank.
B) Check valve :- It is provided in the return pipe to prevent back flow.
C) Baffles :- They are provided to reduce foaming of oil.
D) Breather :- It is provided for air circulation in the tank.
E) Filter :- It remove dirt from the air passing through the breather.
F) Drain plug :- It is provided to drain out used oil.
G) Sampling tap :- It is provided to collect sample of for testing of viscosity, etc.
The reservoir capacity should be three times the flow rate of the pump.
Rectangular shape helps for better heat dissipation per unit volume.
