Guide to the Air Compressors

 An air compressor is a device that converts force into energy stored in compressed air. This device is widely used in home and industrial applications. To buy an air compressor, you need a complete guide about this device. It is also better to be familiar with the types of air compressors. So we suggest you read this article to the end.

An air compressor is a pneumatic device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When the tank's pressure reaches its engineered upper limit, the air compressor shuts off. The compressed air, then, is held in the tank until called into use.[1] The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes. When tank pressure reaches its lower limit, the air compressor turns on again and re-pressurizes the tank. An air compressor must be differentiated from a pump because it works for any gas/air, while pumps work on a liquid.



Applying best energy management practices and purchasing energy-efficient equipment can lead to significant savings in compressed air systems. Use the software tools, training, and publications listed below to improve performance and save energy. more information in this link



Air Compressors Types

Air compressors are divided into two general categories, Positive Displacement and Dynamics, and we will examine each separately.

Positive Displacement:
For the case of positive displacement air compressors, the air is forced into a variable volume chamber, in which it undergoes an increase of pressure due to decreasing the volume of the chamber. This process is what we call “air compression”.

Upon reaching to some maximum pressure, the compressed air is ready to be discharged into the air compressor’s outlet. At this point, a valve opens to guide the compressed air out of the chamber.





Lobe Type Air Compressors
Lobe compressors are one of the types of air compressors which incorporate two intermeshing rotors rotated by two parallel shafts. Each of the two rotors will most likely have two lobes; nonetheless, tri-lobe rotor designs are also available. Read more

Introduction of electric motors and types

Image
  You've probably heard of electric motors by now. A critical piece in all electrical appliances. In this article, we will introduce electric motors in detail and examine its types, so stay tuned. An electric motor is a component that converts electrical energy into kinetic energy. Most electric motors are  electromagnetic -based. Most electric motors are rotary, but there are also linear motors. In a rotating motor, the moving part (usually inside the engine) is called the impeller or rotor, and the fixed position is called the station or stator. The motor consists of electric magnets wound on a frame. Although this frame is often referred to as armature, the term is often misused. Types of Electric Motor Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of various phase (see single-phase, two-phase, or three-...

Introduction and review of Suspension Insulators and Strain Insulators

Image
  In this article, we will have a detailed explanation and review of Suspension Insulators and Strain Insulators. Join us and read this article. First, we will introduce Suspension Insulators, and after reviewing it, we will submit Strain Insulators What is Suspension Insulators  ? The suspension type insulator consists of several insulation parts connected in series and forms a string. In suspension insulators, each porcelain discs is designed to work at 11 kV, and as the operating voltage increases, the number of discs in the string and in series increases as well. For example, the number of insulator discs required is 12 in 132 KV transmission lines.  Read More in Linquip What is Strain Insulators  ? According to  Wikipedia , A strain insulator is an electrical insulator designed to work in mechanical voltage (strain) to withstand the pull of a suspended electrical wire or cable. They are used in overhead electrical wiring to support radio...

Everything you should know about HVAC

Image
What is HVAC? What do you know about it? What is its use? In this article, we will take a closer look at HVAC, so join us to get the answers to these questions and any other questions about HVAC. The importance of HVAC Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of  mechanical engineering , based on the principles of thermodynamics, fluid mechanics and heat transfer. As was mentioned earlier, an  HVAC system  is intended for thermal control of areas as well as comfort for occupants. Temperature is factor that affects the performance and health status of many systems. Take the case of a server room temperature as an example for which high temperature adversely affects the system’s reliability and operation of the servers is a great source of heat ge...
