DSL 106 W3 D2 Flashcard

Front

What type of pump does a PC system use in closed-center systems?

Back

Variable-displacement pump

Front

What does a PC hydraulic system do when a DCV is actuated according to one hydraulic pump manufacturer?

Back

The PC pump matches the flow requested by the DCV.

Front

Which of the following is a type of PC System Pump Design?

Back

Variable inline axial piston

Front

What is the function of the pump compensator in a variable-displacement pump?

Back

It shuts off pump flow when the system reaches high pressure.

Front

What can be a consequence of not having relief valves in LSPC systems?

Back

Overpressurization and potential equipment failure.

Front

Define a fixed-displacement pump.

Back

A pump that delivers a constant flow rate regardless of the pressure in the system.

Front

What is a variable-displacement pump?

Back

A pump that can change its flow rate based on the system's demand.

Front

Explain the role of a directional control valve (DCV) in a hydraulic system.

Back

A DCV directs the flow of hydraulic fluid to different parts of the system.

Front

What is the purpose of a relief valve in hydraulic systems?

Back

To prevent overpressure by allowing fluid to escape when pressure exceeds a set limit.

Front

Describe the function of a pump compensator.

Back

It adjusts the pump's output to maintain system pressure and flow requirements.
