Pneumatic / Hydraulic Jack Set

SE-8764A

Notes to the Teacher

Description

The Transparent Devices Hydraulic/Pneumatic Jack Set includes a rugged stand that holds a large
cylinder-and-piston syringe, four smaller syringes, and flexible tubing assemblies with valves and
quick-connect fittings, together with this manual.

Purpose

This set makes possible a number of teacher demonstrations and student experiments involving fluids
and air. These include:

 The operation of a pump

 The hydraulic/pneumatic jack as a force transformer (simple machine)

 The difference in the ability of gases to compress compared to liquids
 Force, area, and the concept of pressure

 Boyle’s law, using air or other gases

Care and use

Some simple precautions will help ensure that this set provides years of use:

 When lifting a load such as a stack of books, center the load, do not lift too heavy a load, and do

not lift the load above the 40 cc mark on the syringe.

 If lubrication of the syringes is needed, use only glycerin or silicone oil. Do not use petroleum-

based lubricants, as this will quickly damage the seals.

 Use only light finger pressure on the quick-connect fittings. Do not over-tighten.
 If lost or damaged, replacement parts are available.

Safety

Please teach and expect safe behavior in your classroom and lab. Safety considerations call for
supervision of students at all times, safety eyewear, no horseplay, and immediate reporting to the
instructor of accidents or breakages, among others.
