Objectives: The electric drill is one of the most widely used power tools. It has many uses and is simple to operate. Electric drills can be found in a variety of shapes and sizes, from a light household duty to the heavy-duty industrial grade hand drill and drill press. One variation of the electric drill is the hammer drill or rotary hammer. The hammer drill is a tool used for making holes in concrete and masonry.

Grinders are commonly used for shaping and finishing metal and other materials. Hand grinders are available in sizes ranging from those designed to do the intricate work of the die grinder to that of the 7-inch heavy-duty disc grinder.

186056
Pneumatic Hand Tools

Objectives: Pneumatic tools are used in many areas of maintenance, construction, and production work. These tools harness the power of compressed air and convert this power to useful work. Compressed air can be a very powerful energy source. However, due to this power, you must be extremely careful when using these tools.

Pneumatic tools are normally made much heavier than standard-duty hand and power tools. You will notice this fact as soon as you lift an impact wrench or framing nailer. The cases of the tools are made intentionally heavy to contain the stresses of the impact hammers or piston and to absorb the normal day-to-day abuse that the tool takes. You have probably seen someone remove a tire's lug nuts with a pneumatic impact wrench. The operator picks up the wrench and blasts off four or five bolts. Next, the wrench is dropped the six inches or so to the floor while the operator's hands move to quickly grab the wheel and rim. Come back to this same shop a year later, and you will probably see the same wrench being used after thousands of tires have come and gone. The tool's case may be nicked and grooved, but if properly cleaned and lubricated, the tool could last for many thousand more tires.

This text discusses the selection, use and safe practices of using different types of pneumatic tools.

Industrial Fuses

Objectives: All electrical and electronic circuits, from the small ones in our homes to the large ones in industry, need to have circuit protection. This protection guards against too much current flowing in the circuit. Too much current in a circuit can cause serious damage. There are two different methods of protecting a circuit: fuses or circuit breakers. This study unit focuses on fuses.

The Industrial Fuses study unit covered the various types of fuses. Here the second kind of protective device, the circuit breaker will be examined.

Most people are familiar with the molded-case circuit breakers used in our homes. The home load center will normally contain a main circuit breaker that protects the entire load center for the home, and smaller circuit breakers that protect the various branch circuits.

An industrial control panel is not much different from a home's load center. A large circuit breaker or fuse system is usually located at the main disconnect that supplies the control panel. Each circuit will then contain a smaller circuit breaker or fuse system to protect the branch circuits inside and outside the panel.

This study unit will look at the types of circuit breakers that are commonly used in industry; how they are designed and how they work. We will also look at typical branch circuits for single-phase and three-phase loads.

Objectives: Industrial equipment is rarely connected to a control system or to other equipment using direct wiring methods. Instead the power and signal cables are often hooked to the equipment using plugs and receptacles. Trainees will find a wide variety of plugs and receptacles used in industry.

In many cases, an entire work cell or area of a plant is designed and built in a factory, separate from where the equipment will be installed. The machines will interconnect to each other and to the main control system using one of a number of plug and receptacle systems.

When troubleshooting, some can be diagnosed simply by looking at their contacts or actuators. But many more switches consist of intricate, sometimes solid-state circuitry, and use component properties such as inductance, capacitance, and magnetism.

These types of switches are found in the basic electrical circuits and in the control rooms of industrial facilities. They also are used in the regulation of such process-line variables as flow, level, temperature, and pressure.

Industrial Relay Ladder Logic

Objectives: Control circuitry in industrial applications is the brain behind the brawn of motorized power. Motors require one element to perform the work they are designed to do: power. How they get the power is not a concern of the motor, but it is a major concern to the developers of control systems.

Industries, especially those involving sequential operations such as mills, refineries, chemical plants, manufacturing conveyor systems, and any of the processes that require certain events to happen at certain times, require well-designed control systems.

To properly provide sequential operation of these events, a control system designer must start with what is referred to as logic, or sequential events. A ladder diagram is the main tool used by control systems designers to design a control system that causes certain events to happen at certain times.

Once the design is developed, it is up to the electrician or technician to install the system and, later, to maintain it.

086081
Industrial Relays, Contractors, and Solenoids

Objectives: In the Industrial Relay Ladder Logic study unit, we learned that an electromagnetic relay is an electromechanical switch made up of an electromagnet and a set or sets of contacts.

An electromagnet is created by passing electrical current through a wire, causing a magnetic field to form around the outside of the wire. A ferrous metal, which is a metal that contains iron and can be magnetized, will be pulled toward the magnetic field being emitted by the energized coil. If the ferrous metal is shaped into a rod or plunger and is inserted in the middle of the coil, the magnetic field will pull it into the coil's core, and the rod or plunger will try to align itself in the center of the field. If the bar or plunger is mechanically connected to a contact bar, the device is a relay, starter, or contactor. If the plunger in a coil is mechanically connected to a valve or other operating mechanism, the device is a solenoid.

The magnetic field will pull the contact or mechanical device with it, and cause a movable contact to either make contact or break contact with a stationary contact (in the case of a relay), or cause a mechanical action (in the case of a solenoid).

This study unit will delve deeper into the various types of industrial control relays, magnetic starters, contactors, and solenoids, covering their operating principles, construction, components, and applications.
