403 - Lab

Question 1

Regeneration

Answer 1

Only contains a DCV and Double acting cylinder.
Extension is faster than retraction.
Retraction has more force than extension.

Question 2

Syncronization in Parallel

Answer 2

Contains DCV and two Double acting cylinders, and flow control valves.
If one cylinder fails, the other can still work.
Application would be opening two gates, you would still want at least one to work.

Question 3

Syncronization in Series

Answer 3

Contains DCV and two double acting cylinders.
If one cylinder fails then the other one will not work.
Application would be lifting a barge.
Costs less than sync in parallel.

Question 4

Meter-In Circuit

Answer 4

Contains in order DCV, Flow control, P1, Hydraulic motor, P2, and pressure relief.
The circuit is metered by a flow control valve before the hydraulic motor.

Question 5

Meter-Out Circuit

Answer 5

Contains in order DCV, Motor, P1, flow control, P2.

Flow control is on the backside of the circuit to control the discharge flow.

Question 6

Pressure Reducing Circuit

Answer 6

Contains in order DCV, Pressure relief valve, and double acting cylinder.
Acts like Meter-In.

Question 7

Counterbalancing Circuit

Answer 7

Contains in order DCV, hydraulic motor, pressure relief valve.
Balances pressure from the output end.
Acts like Meter-Out.

Question 8

Sequencing Circuit

Answer 8

Contains DCV to pressure relief valve to Hydraulic cylinder. Also DCV to hydraulic cylinder.
Makes one happen fully then the other. Cylinder must extend for the motor to run.
