EXPLORER II INDUSTRIAL HYDRAULICS
A Comprehensive Maintenance Training System For Industrial Hydraulics
The Explorer II Industrial Hydraulics Training System provides the components
and hands-on training required to effectively troubleshoot and repair
hydraulics systems used in modern industry. It includes a user manual and
instructor's guide which focus on the background, applications and
maintenance of hydraulics equipment.
The curriculum begins with the fundamentals of hydraulics, which can be used
as either an introduction to the technology or as a review of key
principles. Additional sections focus on different types of valves,
cylinders and hydraulic devices like hydraulic jacks and regenerative
circuits.
A complete industrial component panel with eye level gauges is mounted on a
slanted stainless steel surface for easy access when conducting experiments.
A lockable storage area behind the panel provides space for manuals and for
additional components. Removable components on the panel and specialty
components from TII that expand the capabilities of the system can be
mounted on the T-slot surface in front of the panel. Mounting hardware is
included.
Explorer II can be mounted on a mobile training bench that has cabinet space
for a hydraulic power system and allows the unit to be wheeled between
classrooms. The portability and rugged design of the training system allow
it to meet demanding training schedules.
The Explorer II is one of four building blocks in the advanced Explorer
Series of technology systems. The other advanced modules address the
principles and applications of industrial pneumatics, electromechanics and
programmable logic controllers. They are designed to interface with the
Explorer II, and can be brought together using mobile benches available from
TII. A major advantage of the TII system over traditional training programs
is that each segment can also be operated separately, giving trainees more
space and instructors greater flexibility.
SPECIFICATIONS
The Explorer II is a complete education/training system that covers hydraulic
technology in its four areas of instruction: Fundamentals, Applications,
Physical Properties and Maintenance. It is constructed of an extruded and
welded aluminum "U" channel frame with a formed sheet steel shell. The
system is modular in design so that it may be used as a stand-alone table, on
a counter top or integrated into a bench configuration with other TII
trainers. The panel includes two sections:
1. The Instrumentation Section of the panel is mounted
at eye level for easy reading of gauges. The panel is constructed of 16
gauge chrome plated and brushed steel. All gauges, cylinders and other
instruments have been identified in large lettering on the panel. The
Instrumentation Section includes a system pressure gauge, two in-line
pressure testing gauges, a four-port pressure manifold, a four-port return
manifold, a 24-volt DC power supply and a momentary switch with output jacks.
CURRICULUM
The Explorer II curriculum was designed and reviewed by a panel of
experienced high school and community college teachers, as well as industrial trainers.
Courseware includes a user manual and instructor's guide with 42 units of
activities and instructional support. Each of the four necessary levels of
instruction includes background study of the topic, observational and
hands-on experiments, application exercises, and mathematical formulas for
proving results.

2. The Component Panel is mounted at an angle for ease
of use when building circuits. It is constructed of 16-gauge chrome plated
and brushed steel and all instruments are clearly identified. The component
panel includes: a 4-way, 2-position solenoid directional control valve; a
relief valve; a sequence valve; a pressure reducing valve; a compensated flow
control valve; an uncompensated flow control valve; a needle valve; a check
valve; a double acting cylinder (5" stroke, 1-1 /16" bore); and a double
acting cylinder (5" stroke, 1-1 /2" bore). The Work Surface
at the bottom of the component panel is used for conducting experiments and
building circuits.
Additional Components include a 4-way, 3-position
lever-operated directional control valve, a tandem center spool, a
viscometer, a thermometer, a flowmeter, a piloted check valve cartridge, a
power cord for the solenoid valve, a load spring kit, two T-fittings, two
hose couplings, eight 24" hydraulic hoses, four 48" hydraulic hoses, and a
7/8" open-ended wrench.
The Storage Compartment is behind the component panel
and accessed through a hinged door with a lock. It has been designed for
storing hoses and extra components. All components, hoses, instruments and
fittings are industrial grade design. All directional control valves are
removable and dissectible. The actuators and spools on the directional
control valves are interchangeable. All fittings are ball-check quick
connect/disconnect.
Options to expand the capabilities of the system include
a wide range of specialty components which can be purchased for mounting on
the system's T-slot experiment surface. Each component comes complete with
mounting hardware, instructions and an application lesson. Also, the
EXPLORER II-HSP is a mobile training system which includes
the Explorer II, a mobile bench, and a hydraulic power system.
