What Is A Boiler?A boiler is defined as "a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is superheated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy."
What is a condenser?
Many people have air conditioners but are not aware of how or what makes them work. A condenser is simply one component of an air conditioner. Whether you have an outdoor air conditioner or a window unit air conditioner your air conditioner contains a condenser.
Condensers are used in outdoor air conditioning systems as well as heat pump systems. Condensers in an air conditioning unit have very few controls. They will have an on and off switch. Occasionally these air conditioners will also have a brown out option. This option shuts down the compressor when the electrical current is low.
Occasionally=Sometimes
brown out=کاهش جریان برق
A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. A condenser is a major component in a air conditioning or heat pump unit. It moves air across the coils to facilitate the transfer of heat

What is pump?
A pump is a device used to move fluids, such as gases, liquids or slurries. A pump displaces a volume by physical or mechanical action. One common misconception about pumps is the thought that they create pressure. Pumps alone do not create pressure; they only displace fluid, causing a flow. Adding resistance to flow causes pressure. Pumps fall into two major groups: positive displacement pumps and rotodynamic pumps. Their names describe the method for moving a fluid

Turbines are the core of our civilization. Practically every form of electric power is generated by a turbine. When we say coal power, nuclear power, hydrothermal power, etc., we mean using some energy source to agitate a gas which then drives a turbine and generates power. A turbine is one of the most common types of engines, where an engine is defined simply as something that takes an input and generates an output. Along with heat engines and motors, turbines make up the vast majority of dynamic machinery
civilization=تمدن
agitate=shake=cause to move in an irregular manner
Gas turbines are one of the most flexible type of turbine, and are used to power a variety of mobile machines above a certain size, jets being the most famous application. Even the space shuttle causes a gas turbine to combine fuel at tremendous rates. Because they can spin at extreme rates, gas turbines allow a huge amount of power to be packed in a relatively tiny space. A typical gas turbine engine operates between 3,000 and 10,000 rpm, and smaller variants can climb above 100,000 rpm. A recently constructed matchbox-sized gas turbine spins at 500,000 rpm and generates 100 watts.
mobile=moveable=flowing freely
Scientists want to push these turbines to operate at a million rpm or above, but making this possible without melting the assembly can be tricky.
To extract the greatest efficiency from turbines, they are often chained together. This can lead to efficiency levels of 60% or higher, quite amazing in the world of thermodynamics. Understanding the operation of turbines in detail is the province of mechanical engineers, though anyone who works with machines is probably familiar with the basics

Machine
Machine is a device that can be used to do work. Machines are designed to make life easier for us. Some machines perform tasks that would be impossible to do without them. We use machines all the time. Industries use drill presses, lathes, and grinding machines to make products we use. Businesses depend on computers, copying machines, and fax machines. Automobiles, buses, and airplanes transport people swiftly over great distances. Trucks, railroads, and ships haul goods to and from markets. Without machines, the residents of our cities would find it more difficult to live, and farmers could not raise enough food to feed us
lathe=tool which is used to cut and shape (wood, metal, etc
grinding=سمباده زدن
swiftly=quickly=speedily=immediately
haul=carry

People have constructed a wide variety of machines to satisfy their needs. Early people made stone axes that served as weapons and tools. The machines that were gradually developed gave people great control over their environment (physical surroundings). To operate these improved machines, people harnessed the energy of falling water and of such fuels as coal, oil, and the atom. Today, we use so many machines that the age we live in is often called the machine age

drill press
A drill press is an essential tool for drilling precisely spaced holes or boring to exact depths. With the right set-up you can bore at almost any angle without fear of the drill bit walking or reaming the hole out of round. With the right attachments, a drill press can also serve as a spindle sander, mortise machine or a pocket hole machine. Given their versatility and relatively low cost, a drill press is an excellent investment for most any shop

Lathe
The purpose of a lathe is to rotate a part against a tool whose position it controls. It is useful for fabricating parts and/or features that have a circular cross section. The spindle is the part of the lathe that rotates. Various workholding attachments such as three jaw chucks, collets, and centers can be held in the spindle. The spindle is driven by an electric motor through a system of belt drives and/or gear trains. Spindle speed is contolled by varying the geometry of the drive train.
jaw chuck=سه نظام فک دار
collet= small metal band or ring
The tailstock can be used to support the end of the workpiece with a center, or to hold tools for drilling, reaming, threading, or cutting tapers. It can be adjusted in position along the ways to accomodate different length workpices. The ram can be fed along the axis of rotation with the tailstock handwheel.
ram=کوبه
The carriage controls and supports the cutting tool. It consists of:

Grinding
Grinding
Grinding
Grinding is a finishing process used to improve surface finish, abrade hard materials, and tighten the tolerance on flat and cylindrical surfaces by removing a small amount of material.
abrade=ساییدن=سنگ زدن
tighten=کیپ کردن=تنگ کردن
In grinding, an abrasive material rubs against the metal part and removes tiny pieces of material. The abrasive material is typically on the surface of a wheel or belt and abrades material in a way similar to sanding. On a microscopic scale, the chip formation in grinding is the same as that found in other machining processes. The abrasive action of grinding generates excessive heat so that flooding of the cutting area with fluid is necessary.
abrasive=سمباده
excessive=extreme
Reasons for Grinding
Reasons for grinding are:
The material is too hard to be machined economically. (The material may have been hardened in order to produce a low-wear finish, such as that in a bearing raceway.)
Tolerances required preclude machining. Grinding can produce flatness tolerances of less than ±0.0025 mm (±0.0001 in) on a 127 x 127 mm (5 x 5 in) steel surface if the surface is adequately supported.

Solar Energy Basics
Solar panels installed on a home in Colorado.
Solar is the Latin word for sun—a powerful source of energy that can be used to heat, cool, and light our homes and businesses. That's because more energy from the sun falls on the earth in one hour than is used by everyone in the world in one year. A variety of technologies convert sunlight to usable energy for buildings. The most commonly used solar technologies for homes and businesses are solar water heating, passive solar design for space heating and cooling, and solar photovoltaics for electricity.
photovoltaic=producing electricity under the influence of light or radiation
Businesses and industry also use these technologies to diversify their energy sources, improve efficiency, and save money. Solar photovoltaic and concentrating solar power technologies are also being used by developers and utilities to produce electricity on a massive scale to power cities and small towns
diversify=make different= variegate
massive=enormous

Centrifugal Pump
A centrifugal pump is one of the simplest pieces of equipment. Its purpose is to convert energy of an electric motor or engine into velocity or kinetic energy and then into pressure of a fluid that is being pumped. The energy changes occur into two main parts of the pump, the impeller and the volute. The impeller is the rotating part that converts driver energy into the kinetic energy. The volute is the stationary part that converts the kinetic energy into pressure
impeller=پروانه
volute=حلقه
impeller=پروانه
volute=حلقه
