Pneumatics Flashcards - MOY

Front

Which type of device could give a pressure reading of -0.2 bars? (Negative pressure)

Back

Vacuum gauge

Answer explanation

A vacuum gauge is designed to measure negative pressure, such as -0.2 bars, indicating a vacuum. Other pressure gauges measure positive pressure, making vacuum gauges the correct choice.

Front

Pneumatic actuators are used to convert:

Back

the energy stored in a pressurized fluid into motion.

Answer explanation

Pneumatic actuators convert the energy stored in pressurized air into motion, enabling various mechanical movements. Because air is a fluid, this makes the correct choice 'the energy stored in a pressurized fluid into motion.'

Front

A safety relief valve is used to

Back

avoid excessive pressure build-up

Answer explanation

A safety relief valve is designed to avoid excessive pressure build-up in a system, ensuring safe operation by releasing pressure when it exceeds a predetermined limit.

Front

Compressors usually pump air into

Back

receivers

Answer explanation

Compressors are designed to pump air into receivers, which store the compressed air for later use. This is essential for maintaining pressure in pneumatic systems. Actuators like cylinders and motors use the air to create movement.

B

Front

Which pneumatic device converts the energy of a pressurized fluid into motion?

Back

actuator

Answer explanation

Actuators, which include both cylinders and motors, convert the energy of a pressurized fluid into motion, making 'All of the above' the correct answer.

Front

Purpose of an accumulator in a pneumatic system?

Back

Mitigate the effects of long tubing

Answer explanation

An accumulator helps mitigate the effects of long tubing by storing compressed air, which can smooth out pressure fluctuations and improve system responsiveness.

Front

Name three parts that could be used to build a basic cheese press.

Back

Pushbutton valve

shut off valve

start up valve

cylinder

tubing

air supply

receiver

Answer explanation

As you can see, the main element of the cheese press is a cylinder that applies the pressure on the cheese. Because 'Pushbutton, cylinder, tubing, air supply' is the only answer that includes a cylinder, it makes sense it is the correct answer. To work correctly, the press also needs a tubbung, air supply, and some way to turn it on and off, like a pushbutton.
