Lesson
1
Prepare Electrical and Hydraulic
Tools
In a hydraulic system, fluid power provides the “muscles” or power to do work, while
control provides the “brain” to command system operation. Control of a hydraulic
system may range from the simple starting and stopping of the system controlling
extension and retraction of several cylinders in a completely automated factory.
A hydraulic system can be controlled either manually or automatically:
Manual control: system operation is sequenced and commanded by an
operator that decides each action take.
Automatic control: system operation is sequenced and commanded by a controller that decides each action to take. Automatic control can be accomplished by means of:
a. Electric signals (electrical control): b. Compressed air (pneumatic control): c. Mechanical link (mechanical control):
Manual control is good for system operations which do not require constant repetition. An earth-moving truck such as those used in construction, farming, and mining is a common example of a machine requiring manual control. Since the operator must constantly change the position to where the shovel digs and the depth of operations is not repetitive.
In systems requiring the repetition of the series of operations, however, it would be inefficient to manually shift hydraulic valves each time the direction of oil flow needs to be change.

3. A Heat Gun is a device used to emit a stream of hot air. Heat guns can be used to dry and strip paint, apply heat shrink tubing,
apply shrink film, dry out damp wood, bend and weld plastic, soften adhesives, heat
shrink wrap on packaging, and thaw frozen pipes, depending heavily on heat output.
4. Hydraulic Bender - A hydraulic pipe bender is used for bending almost all types
of pipes except PVC conduit pipes. The bending capacity of hydraulic pipe benders
varies as per the strength, power and performance. The hydraulic pipe benders are designed with extra power for large jobs.
They are suited for various types of bending and forming applications.
