Welding, as we learned in a previous article, deals with joining together materials with the combination of heat and/or pressure. There are several techniques to achieve this and one of the most commonly used is the electric arc method. In this article you will see the basic principles of the same.
What do you do when you want to stick stamps on a letter you are posting, or when the fascias of your mobile breaks? I for one do not use my saliva or buy new fascias in such situations. Rather I use some sort of glue for the job. Learn how engineers use the process of welding metals to do the same.
Marvels of engineering excellence are all around us and sometimes we get so absorbed in their beauty and grandeur that we seldom stop to think how those items were first thought and later transformed into the material shape that they possess. Computer aided design is one key element.
Manufacturing of various products is carried out with the help of different kinds of machines. Lathe machine is one of the oldest, yet most useful and versatile of such kind of manufacturing machines, and can be used for numerous manufacturing operations on a wide range of materials.
We all take pride in showing off our latest automobiles and getting them decorated with the fanciest of accessories (at least most of us), but have you ever thought what makes the vehicle move at a speed which thrills (don’t forget the speed limits by the way)? Find out more about engines!!
In condensers the refrigerant gives up the heat that is has absorbed in the evaporator. There are three main types of condensers: air cooled condensers, water cooled condensers and evaporative condensers.
In throttling devices the pressure of the refrigerant drops down suddenly and due to this its temperature also reduces drastically. This article describes various types of throttling devices being used for refrigerator and air-conditioning systems.
Refrigerants are the life blood of the vapor compression system. The refrigerant flows continuously through the vapor compression cycle, absorbing the heat in the evaporator and releasing it in the condenser. It undergoes various phase changes while flowing though the cycle.
The refrigerant undergoes various changes throughout the vapor compression cycle and it is in the evaporator where it actually produces the cooling effect. The evaporator is usually a closed insulated space where the refrigerant absorbs heat from the substance or food to be cooled.
The refrigerating compressor is considered to be the heart of refrigeration and air-conditioning systems. The compressor compresses the refrigerant and consumes most of the power of refrigerating and air-conditioning units.
In many cases especially in places of heavy rainfall, the dehumidification carried out by air-conditioners is not sufficient because the moisture content of the air is extremely high. In such cases portable dehumidifiers are very useful and convenient to use.
Mechanical engineering is a very vast field and encompasses various aspects and subfields including but not limited to power generation, manufacturing, transportation and so forth. Read on to find out more about this exciting and vibrant field of engineering.
Manufacturing of different products is a very interesting and equally challenging subject and one certainly needs to know the basics of different types of prominent manufacturing processes which are in use in the industry today. This article tells you about the main types manufacturing processes.
Central air conditioning plants are used for applications like big hotels, large buildings having multiple floors, hospitals, etc, where very high cooling loads are required. The article describes various possible arrangements of central air conditioning plants.
This article describes the arrangement of compressors in the package air conditioners with multiple compressors. It also describes the capacity control system in these units.
Nearly three-fourths of this earth is filled with water and we all know that sailing through the high seas is a great adventure as well as a career. This is where the concept of marine engineering comes in the picture and this article would tell you some interesting facts about the same.
As we know mechanical engineering is mainly related to the science of machines in the broad sense of the word. Machines are mainly used for production of other products and this is where the concept of manufacturing technology comes in the picture. Find out more about this interesting technology!
Manufacturing cycle is the complete cycle of processes which are involved from the very beginning of placing an order to the other extreme of the manufactured product going into the hands of the end consumer. Read on to find out more about these intermediate processes and a brief description thereof
