Power Pack Component


5/17

Engine

Engine generates power to activate hydraulic pump that force

hydraulic fluid through the system to power CTU component Type of engine that is commonly used is diesel engine

Commonly used Caterpillar or Detroit engine

Detroit Engine Caterpillar Engine

Hydraulic Pump

Hydraulic pump drawshydraulic fluid from reservoir

and then force it to flow to

various CT component

Hydraulic pump that used in CT

power pack may be vane pump

or piston pump

Hydraulic Reservoir

Reservoir main function:

Store hydraulic fluid

Allows the fluid to cool

Allows settlement of dirt andmetal particles

Allow entrained air to be

released

Filter and Strainer

Strainer- Coarse filter

- Placed in reservoir suction line

- Can be cleaned and Re-use

Filter

- Fine filter

- Placed in reservoir return line

- Cant be cleaned and should be

replaced

Pressure Control Valve

Pressure control valve limit the maximum systempressure and reduce pressure in certain circuit

There are 3 types valve:

Relief Valve

Unloading Valve

Pressure Reducing Valve


10/17

Accumulator

Accumulator is installed in

hydraulic circuit to storage

energy and to smooth out

pulsation

There are two type of

accumulator, piston and

bladder. The most commonand popular is bladder type


11/17

Heat Exchanger

Located on a return line to the

reservoir because cant withstand

high pressure

It is used to cool the hydraulic fluid

before get into reservoir

Heat exchanger can use water or airto cool fluid
