Heat transfer is the movement of thermal energy from one object or system to another. This can occur in a variety of ways, including conduction, convection, and radiation. Each method of heat transfer plays a significant role in the everyday world, from cooking food on a stove to heating buildings …

Nondestructive Testing (NDT) is a group of inspection techniques used to evaluate the properties of a material, component, or system without causing damage to the object being tested. Here are some common NDT methods: Ultrasonic Testing (UT) Radiographic Testing (RT) Magnetic Particle Testing (MPT) Liquid Penetrant Testing (LPT) Eddy Current …

A valve is a mechanical device that controls the flow of fluid and pressure within a system or pipe. A valve controls the system or processes fluid flow and pressure by stopping, starting, and Regulating it. Types of valves and their Classification Although all valves have the same basic components …

Some precision measuring tools are more accurate than others, but all can be read at least to the nearest 0.001 inches or 0.02 millimeters. There are four broad categories of precision measuring tools: • outside measuring tools, for measuring the diameter of a shaft or the thickness of a block; …

Some welding processes resemble both soldering and brazing and that molten metal is applied to produce a joint between the two pieces. However, in welding, the added metal is, more often than not, of similar composition to the metals being joined, and the joined pieces are melted locally so differences …

In almost any power, chemical, or mechanical system, heat must be transferred from one place to another or from one fluid to another. Heat exchangers are used to transfer heat from one fluid to another. A basic understanding of the mechanical components of a heat exchanger is important to understand …

The purpose of an air compressor is to provide a continuous supply of pressurized air. An air compressor is a machine to compress the air and to raise its pressure. The air compressor sucks air from the atmosphere, compresses it and then delivers the same under high pressure to a …

Today we will discuss about typical Mechanical Valve functions and basic parts of Valve. Valves are the most common single piece of equipment found in industrial facilities. Although there are many types, shapes, and sizes of valves, they all have the same basic parts. This chapter will review the common …

Positive displacement pumps operate on a different principle than centrifugal pumps. Positive displacement pumps physically entrap a quantity of liquid at the suction of the pump and push that quantity out the discharge of the pump. A positive displacement pump is one in which a definite volume of liquid is …

Improper operation of centrifugal pumps can result in damage to the pump and loss of function of the system that the pump is installed in. It is helpful to know what conditions can lead to pump damage to allow better understanding of pump operating procedures and how the procedures aid …

Today we will discuss about (BFWP) boiler feed water pump working principle and operation of a boiler feed water pump. The boiler feed pump function is to supply pressurized feed water to the boilers maintain the water inventory at various operating loads. Boiler feed water pumps are commonly centrifugal pumps. To …

Centrifugal pump Components vary in design and construction from simple pumps with relatively few parts to extremely complicated pumps with hundreds of individual parts. Some of the most common components found in centrifugal pumps are wearing rings, stuffing boxes, packing, and lantern rings. Wearing Rings Centrifugal pumps contain rotating impellers …
