Hydraulic Press Puzzles – Test Your Understanding!
🔍 Puzzle A:
Q: Name the parts labelled by the letters X and Y.
X → Press plunger (cylinder Q),
Y → Pump plunger (cylinder P)
Y → Pump plunger (cylinder P)
🔍 Puzzle B:
Q: What happens to valves A and B, and water levels in the two cylinders when the lever arm is moved down?
Valve A opens, Valve B closes,
Water moves from cylinder P to Q,
Water in P decreases and water in Q increases.
Water moves from cylinder P to Q,
Water in P decreases and water in Q increases.
🔍 Puzzle C:
Q: Why do the valves A and B behave this way when the lever arm moves down?
Pressure increases in cylinder P,
Valve B closes to prevent backflow,
Valve A opens due to higher pressure in the pipe than in Q.
Valve B closes to prevent backflow,
Valve A opens due to higher pressure in the pipe than in Q.
🔍 Puzzle D:
Q: What happens when the release valve is opened?
Plunger Q moves down,
Water from cylinder Q flows to the reservoir,
Pressure is released in Q.
Water from cylinder Q flows to the reservoir,
Pressure is released in Q.
🔍 Puzzle E:
Q: What happens to valve B in cylinder P when the lever arm is moved up?
Pressure in P decreases, so valve B opens upwards.
🔍 Puzzle F:
Q: Why does valve B open when the pressure decreases in cylinder P?
Lower pressure in P allows valve B to open and pull water from the reservoir into P for the next stroke.
🔍 Puzzle G:
Q: What is one use of this hydraulic press device?
It is used to press cotton bales, books, quilts, and similar materials.
