Transcript: Air compressors What is air compressor? Air compressor is a device that converts power into potential energy stored in pressurized air. What is compressor? Variety of air compressors We can classify air compressors according to the design and principle of operation: -reciprocating compressor -rotary-screw compressor -rotary vane pump -scroll compressor -turbo compressor -centrifugal compressor Variety of compressors Reciprocating compressor Reciprocating compressor sucks air to the discharge chamber, close the chamber, compress the air and exhaust air to the tank. Reciprocating compressor Two and one stage reciprocating compressor Reciprocating compressors are divided into: Single-stage reciprocating compressor and two-stage reciprocating compressor. First one is used to pressure around ten bars and efficiency 100 cube meters per hour. Two-stage compressor is used to pressure 7-10 bars. During interstage cooling air heated as a result of preliminary compress air is cooled to the primal temperature before exhaust to the second stage of compression. Rotary screw-compressor Compression of gas in this compressor is feasible because of reducing space between two rotary screws. Sealing depend of screw's design and quality. Rotary screw-compressor Rotary vane-pump Kind of air compressor where twirl vane compress the air. This compressor can work as: vacuum pump, liquid pump. Rotary vane-pump has fine construction so it can be used only to compress gases and clean, self-lubricating liquids. Rotary vane-pump Scroll compressor Also eccentric compressor, compression in this device go ahead by cooperation two spirals. First one is stationary while second is moving around. Space between spirals is getting smaller from suction hole to discharge hole. Scroll compressor Turbo compressor Vanes suck air up and scorch this. In attached tank kinetic energy of the flux convert to potential energy of compression air. Turbo compressors are very efficient. Turbo compressor Centrifugal compressor Centrifugal compressor is marked by radial flow. Air is sucked into rotating rotor with radially placed vanes and is rejected outside impeller by centrifugal force. Air move in radially direction yield growth the pressure and generating kinetic energy. Before air will be introduced to another impeller it has to pass diffuser and spiral where kinetic energy is converting to pressure. On the each compression step is reached certain part of pressure generated by compressor. Centrifugal compressor

Transcript: In simple terms, an air compressor is a device which forcefully pushes air through a hose. Because they serve so many functions, they can be useful to have around the house. As you might expect, you can inflate basketballs, footballs, soccer balls, air mattresses and tires. But you can also attach a blowgun to remove sawdust from your woodworking projects, apply paint or stain with an airbrush, and power a surprising array of tools. Make sure the air compressor is on a flat surface, and check the pump oil level before each use. Next, connect the air hose to the regulator valve and the power tool to the hose. Now you are ready to start the air compressor. Make sure the pressure switch lever is in the "OFF" position. air compressor An air compressor is a device that converts power (usually from an electric motor, a diesel engine or a gasoline engine) into potential energy by forcing air into a smaller volume and thus increasing its pressure. The energy in the compressed air can be stored while the air remains pressurized. air compressor what is an air compressor and why do we need it did you know that thunder is actally is the sound of compressor air exploding When a lightning bolt strikes the earth a second bolt instantaneously travels back to the sky vai the same route. This secondary bolt immediately heats the air surrounding it to around 27,000oC. pictures of air compressor how it works what can i do with a air compressor fun facts anothor air compressor but diffrentkind

AIR COMPRESSOR PARTS AND FUNCTIONS Parts and Functions Air tank / receiver is used for storing or holding compressed air prior to use. AIR TANK AIR TANK This is where the motor and pump are located for added stability and support. EQUIPMENT DECK EQUIPMENT DECK It is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. They can also be used as a source of motion. BELT BELT An electric motor is an electrical machine that converts electrical energy into mechanical energy. ELECTRIC MOTOR ELECTRIC MOTOR It is a physical barrier that encloses belt and prevent employees direct contact with them. BELT GUARD BELT GUARD OUTPUT PORTS OUTPUT PORTS This serves as a passageway of the compressed air from the air tank. An instrument which visually display the pressure of air inside the tank. TANK PRESSURE GAUGE TANK PRESSURE This is responsible for moving or compressing the air. PUMP PUMP It is a hose running from the tank and inserted into the bottom of the pressure switch. UNLOADER LINE UNLOADER LINE It filtered out dirt particles to ensure a trouble-free operation of the system component, like valves and cylinders. It is also essential for reducing machine downtime and for reducing maintenance and energy costs. AIR CLEANER AIR CLEANER Helps to measure the pressure inside the tank and then is used to shut off compressor when air tank reaches the desired air pressure. The switch can turn on compressor when tank air pressure levels drop and more air is needed. SWITCH SWITCH Helps portable air compressor in easy transport and mobility purposes. WHEELS WHEELS Is an electrical cable that connects the air compressor to the main electricity supply via wall socket. CORD CORD Located at the bottom of the tank, this serves as a passageway of the water that is generated inside the tank. DRAIN VALVE DRAIN PORT HOW DOES AIR COMPRESSOR WORKS?

Transcript: Application of Air Compressor Supplying high-pressure clean air to fill gas cylinders Supplying moderate-pressure clean air to a submerged surface supplied diver Supplying moderate-pressure clean air for driving some office and school building pneumatic HVAC control system valves Supplying a large amount of moderate-pressure air to power pneumatic tool Filling high pressure air tanks (HPA), for filling tires Produce large volumes of moderate-pressure air for large-scale industrial processes (such as oxidation for petroleum coking or cement plant bag house purge systems) Demo Video Heavy noise on compressor Compressor clutch is not moving Compressor overheat Slugging Oil not returning to system As the piston reaches top, the pressure starts to fall and the delivery valve starts to close. The residual compressed air remaining in the space again starts to expand as the piston moves down continuing the next cycle When the compressor stops or idles for some time, it is always assumed that there is some residual compressed air left in the cylinder space. This residual air expands when the piston moves down. The pressure drops in the cylinder space at a particular point as the piston moves down, where the pressure inside the cylinder becomes lesser than the atmospheric pressure. Thus this difference in pressure makes the suction or inlet valve open.

One of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When tank pressure reaches its upper limit the air compressor shuts off. The compressed air, then, is held in the tank until called into use. 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 Characteristics of compressors Air Compressor Operation Step 3 1. Dynamic Centrifugal Axial 2. Positive Displacement I. Reciprocating Single-acting Double-acting II. Rotary Helical-Screw Liquid-Ring Scroll Sliding-Vane Lobe Air Compressor Diagram Types of Compressor Failure symptoms on compressor This opening of inlet valve allows fresh air to be drawn inside the cylinder space as the piston still continues to move in the downward direction. The inlet valve will remain open till there is pressure difference between the atmosphere and inside of the cylinder space. As the pressure difference starts to reduce, the inlet valve starts slowly closing. The inlet valve closes completely when there is no pressure difference and then the piston reaches bottom dead center (BDC), and it starts to travel in an upward direction. At this position, both the inlet and delivery valve remains closed. Thus as the piston moves up, the pressure starts to build inside the cylinder space • High precision machining to ensure the compressor confirm with standard • Steady operation, small vibration, low noise and excellent stability • Electrical motor protect device • Wear resistant driver gear • Chrome plated piston rings • Aluminium pistons • Efficient valve plate design • Low energy consumption Example of check list for compressor maintenance The delivery valve starts to open when there is a pressure difference between the cylinder space and air receiver. Let us assume the air receiver is at a pressure of 7 bar. The delivery valve will not open until the pressure inside the cylinder space is slightly above 7 bar. As the piston moves in upward direction, the pressure increases and at some point the pressure grows beyond 7 bar making the delivery valve open. Thus the compressed air is delivered into the air receiver. Introduction of Air Compressor Step 4 Step 2
