A valve is a device used to control the flow of fluid through a pipeline. The fluid can be a gas, liquid, or slurry, which is a mixture of liquid and suspended solids. To keep fluids flowing smoothing and processes operating correctly, it is important to understand how valves operate. In this course, we will discuss common valve parts and materials and different types of valves, their purpose, and how they function.
Although every valve and piping system is unique, some common conditions that exist are pressure drops and high fluid velocities. These conditions are not necessarily bad, and may even be part of the system design. This module will explain the causes and possible solutions of common problems resulting from these conditions.
The right valve type and size must be used to ensure it works properly and maintains the desired setpoint within an acceptable range. This course covers several design properties that determine valve performance, including the valve coefficient, flow characteristic, pressure class, and rangeability.
In most industrial facilities, process systems handle many different types of fluids. The flow of these fluids through plant piping systems is controlled by valves. To keep fluids flowing smoothly, operators need to know how valves operate and how to keep them working properly. In this interactive online course, we will discuss the various uses of valves, their parts, and valve connections.
The purpose of this course is to provide participants with a general understanding of the basic types and operation of valves. The flow of fluids through plant piping systems is controlled by valves.

At the end of this course, participants will have a better understanding of the types, purposes, and applications of various valves.
An actuator can be defined as a mechanism that moves or controls a device, such as a valve. Actuators reduce the need for operators to go to every valve that needs repositioning and operate it by hand. When actuators are used, valves can be repositioned from a central location, such as a control room. This is very important in processes where many valves have to be repositioned accurately and quickly. This course focuses on the design and operation of electric and hydraulic actuators.

Industrial Pneumatic Technology: Aftercoolers, Driers, and Receivers
Air compressors are used in industry to store compressed air or inert gases, which can then be used to power air motors, cylinders, and other pneumatic devices. Clean, dry air is essential for pneumatic systems to function properly, so it is important to remove moisture and contaminants to ensure optimum performance of the system.

Pneumatics is defined as "using pressurized gases to do work." Pneumatic systems are based on the controlled use of compressed air as a source of stored potential energy. By controlling how the air is released, the energy can be turned into movement. Pneumatics are used in handheld power tools, automatic doors, and conveyor systems. They are also used in aircraft for landing gear, flaps, and other instruments. The air brakes on buses and trucks are pneumatic, as well as some exercise machines. Typically, pneumatic systems are more flexible, less costly, and more reliable than many other types of electric motors.
Pumps are essential to virtually all industrial processes and they play critical roles in our everyday lives. Centrifugal pumps convert external rotational mechanical energy into kinetic energy within a liquid. In a centrifugal pump, this is done by accelerating the liquid from the center to the outer rim of a spinning impeller within a pump casing. This course covers the terminology and function of the mechanical components that make up a typical centrifugal pump.
A centrifugal pump is a dynamic machine that has performance characteristics which are partially determined by the environment in which it is operating. One of the best ways to display and study the capabilities of a given pump is with a graph called a pump performance curve. A pump performance curve is actually a set of curves showing a number of parameters versus flowrate. Pump curves can be combined with hydraulic requirements, or system curve, to determine the suitability of a pump for a given task.
Pumps convert rotational kinetic energy, such as that supplied by an electric motor, into hydrodynamic energy, or an increased pressure in a fluid required to make it flow. In order to make a fluid flow, energy, or pressure must be supplied to overcome two fundamental obstacles to flow. One obstacle is created when the elevation of a fluid is increased. The second is presented by the need to overcome the internal resistance of a fluid to flow. This course focuses on how these basic hydraulic concepts apply to piping system evaluation and pumping requirements.
Pump operations and pump maintenance are two closely interrelated topics. Poor mechanical pump maintenance will lead to a loss of hydraulic performance and what may appear to be operational problems. Operational decisions which cause the pump to operate outside of its preferred operation region can lead to physical pump damage which could be misinterpreted as a traditional maintenance issue. It is important to determine the root cause of a problem. This course will cover methods for monitoring pump hydraulic operation and methods for observing and maintaining the mechanical condition of a pump.
Pumps are essential to virtually all industrial processes and they play critical roles in our everyday lives. Pumps have been developed to specifically address a wide range of applications. Selecting the correct pump for a given job can be a daunting proposition. Some pump classifications are based on their hydrodynamic characteristics, some are based on mechanical construction and some are based on compliance with industry standards. In this course, we will help you understand these different classifications and present some of the strengths and weaknesses of the different designs.
The purpose of a pump is to increase the pressure of a liquid and transfer it from one location to another. Although a pump is essential to this goal, it is only one element of a larger system that is required to accomplish liquid transfer. This course will cover some of the mechanical components such as drivers and couplings that support pump operation. It will also cover how the design of a piping system around a pump will affect pump selection and performance.
Pumps are used to move liquids from one place to another by increasing the mechanical energy of the liquid. The energy can be used to raise the liquid to a higher elevation or to increase its velocity or pressure. In a centrifugal pump this is accomplished by rotating an impeller which creates centrifugal force that transfers energy to the liquid. This module focuses on pumping principles and operation guidelines for typical centrifugal pumps.
This course is designed to teach participants how pumps in generating units can be operated efficiently. After completing this course, participants should be familiar with pump operating characteristics such as capacity, head, power, efficiency, and minimum net positive suction head. They should understand how these characteristics can be plotted and read on pump curves, and how pump curves can be used. In addition, they should be able to describe the effects of multiple pump operation and low flow on pump efficiency.
A centrifugal pump converts external rotational mechanical energy into kinetic energy within a liquid. In the most common design of the centrifugal pump, a single impeller spins within a case called a volute. There is an economical limit to the pressure increase that can be achieved with a single impeller. Placing multiple impeller-and-volute stages in a case creates a single centrifugal pump unit capable of continuously delivering much higher discharge pressures than can be created by a single stage pump. This type of pump is called a multistage centrifugal pump. This course discusses some of the mechanical considerations and different designs of multistage centrifugal pumps.
The purpose of this course is to reinforce understanding of positive displacement pumps. These pumps are used in industrial facilities to move many different types of fluids. To keep these pumps working properly, maintenance personnel need to know how they work and how to perform maintenance on them. At the completion of this course, participants will be able to identify the types and operation of positive displacement pumps, describe overhaul preparations, and perform cleaning, inspection, and assembly procedures.
A positive displacement pump works by capturing a given volume of liquid at the suction of the pump, and then mechanically forcing it out of the discharge at a higher pressure. In contrast to centrifugal pumps, in which the flow is affected by downstream pressure, positive displacement pumps (within the limitations of the driver) deliver a nearly constant flow, independent of the downstream pressure. Positive displacement pumps can be categorized as reciprocating or rotary action pumps. This course describes the general characteristics of positive displacement pumps and the principles of operation of various common designs.
Pumps are used to add energy to fluids (gases, liquids, or slurries) to produce flow or increase pressure. This course discusses the construction and operation of the two most basic types of pumps: positive displacement and centrifugal. In addition to how pumps function, it is also covers some of the common terms which are used to describe pump performance.
Pumps are used to add energy to fluids (gases, liquids, or slurries) in order to produce flow or increase pressure. They can perform many different functions, including moving a fluid from one location to another, recirculating a fluid in a closed system, such as in a heating or cooling system, and providing pressure, such as in hydraulic systems. These functions are performed primarily by two different types of pumps: centrifugal and positive displacement. This module describes the most common types of pumps and their applications.

They should also be able to identify symptoms of some common pump problems and explain how to check a pump for signs of problems such as leaks and cavitations.
Most industrial facilities rely on fluid systems made up of piping, valves, pumps, and other components that contain and control fluids. Within these systems are numerous joints and connections which have the potential to leak fluid. Such leaks can be prevented or minimized through the use of compressible materials such as gaskets and packing. This course describes different types of gaskets and packing as well as methods of installation.
Many types of fluid-filled equipment have a rotating shaft that penetrates a stationary housing. In this situation, some method is required to keep the process fluid within the equipment from leaking out. One technique is to compress packing material within a stuffing box against the shaft; another is to use a mechanical seal that consists of two flat faces that are perpendicular to the shaft.
Mechanics who work with mechanical seals need to know how they operate and how they are constructed. This course will cover the principles of operation behind different types of mechanical seals. It will cover common causes of seal failure and how to identify them. It will also demonstrate the removal and replacement of a mechanical seal in a centrifugal pump.

Finally, participants should be able to correct shaft misalignment so that the alignment is within specified tolerances.
Many businesses depend heavily on their fleet of vehicles. In some businesses, such as package or propane delivery, or taxis, the fleet really is the business. In other cases, such as trades like electricians and plumbers, the vehicle is somewhat secondary to the actual job being performed, but no less important. In order for businesses which rely on vehicles to thrive, those vehicles which make up the fleet need to be able to operate safely and properly as close to 100% of the time as possible.
