These are the steps: Shut off compressed air operated equipments (or conduct a test when no equipment is using compressed air). You can change your ad preferences anytime. This knowledge is an important key to getting your costs in line. Dynamic compressors impart velocity energy to continuously flowing air or gas by means of impellers rotating at very high speeds. Compressed air leakage accounts for substantial power wastage. Compressors that meet your every need and demand while at the same time helping reduce our carbon footprint thanks to specially designed green manufacturing practices. Training Session on Energy Equipment Compressors & Compressed Air Systems Presentation from the “ Energy Efficiency Guide for Industry in Asia” www.energyefficiencyasia.org © UNEP 2006 Electrical Equipment/ Compressors. Compressed Air System 1. Create a free account to download. A periodic assessment of the FAD capacity of each compressor has to be carried out to check its actual capacity. Perfect cooling. Moisture drain traps that are used for removal of moisture in the compressed air. Rotary compressors have rotors in place of pistons and give a continuous pulsation free discharge. Compressed Air System. Intercoolers. Reducing delivery pressure. This heat gets dissipated to compressor chamber and leads to hot air intake. The US Department of Energy reports that 70 to 90 percent of compressed air is lost in the form of unusable heat, friction, misuse and noise. Start the compressor and activate the stopwatch. No registration, no watermarks, free to use for anyone. We build the most efficient, most reliable, highest performing, easy-to-use air compressors anywhere. There are two basic compressor types: positive-displacement and dynamic. Two separate compressed air system namely Instrument air system and Plant air system are in use. PRESENTATION 2013 - EMEA Users Conference - Paris Compressed-Air Management with the PI System. This term does not mean air delivered under identical or standard conditions because the altitude, barometer, and temperature may vary at different localities and at different times. Air-dryers that remove the remaining traces of moisture after after-cooler as equipment has to be relatively free of any moisture. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. The method involves starting the compressor when there are no demands on the system. The rotary compressor, therefore, is a continuous duty, air cooled or water cooled compressor package. (click once) Segregating high and low pressure requirements. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. 3.3 Open valve of the compressed air system for five minutes and allow air to pass out. Typical acceptable pressure drop in industrial practice is 0.3 bar in the mains header at the farthest point and 0.5 bar in distribution system. TO THE TRAINER This PowerPoint presentation can be used to train people about the basics of compressors and compressed air systems. Give a brief preview of the ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 3f1293-MjAxM While leakage can come from any part of the system, the most common problem areas are: Couplings, hoses, tubes, and fittings Pressure regulators Open condensate traps and shut-off valves Pipe joints, disconnects, and thread sealants. A typical instrument air skid package contains multiple compressors with dryers and filtration systems that provide high-quality, dry air for a range of applications from pneum We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. We will go through how to perform a simple capacity assessment in a shop floor: Isolate the compressor along with its individual receiver that are to be taken for a test from the main compressed air system by tightly closing the isolation valve or blanking it, thus closing the receiver outlet. In addition to being a source of wasted energy, leaks can also contribute to other operating losses. Air-Pro's ® specially formulated resins are resistant to both synthetic and mineral compressor oils.. See our User Agreement and Privacy Policy. The Pepsi bottling plant in Winnipeg, Manitoba has upgraded both their main 100 psi compressed air. Additional materials that can be used for the training session are available on www.energyefficiencyasia.org under “Energy Equipment” and include: Textbook chapter on this energy equipment that forms the basis of this PowerPoint presentation but has more detailed information Quiz – ten multiple choice questions that trainees can answer after the training session Workshop exercise – a practical calculation related to this equipment Option checklist – a list of the most important options to improve energy efficiency of this equipment Company case studies – participants of past courses have given the feedback that they would like to hear about options implemented at companies for each energy equipment. Operating a compressor at 120 PSIG instead of 100 PSIG, for instance, requires 10 per cent more energy as well as increasing the leakage rate. Also, the compressor capacity is directly proportional to the speed. Calculate the capacity as per the formulae given. In addition, by forcing the equipment to run longer, leaks shorten the life of almost all system equipment (including the compressor package itself). This is an important consideration when selecting compressors based on reported values of efficiency. The location of air compressors and the quality of air drawn by the compressors will have a significant influence on the amount of energy consumed. Wet air receiver too far from prefilter. The centrifugal is a continuous duty compressor, with few moving parts, that is particularly suited to high volume applications-especially where oil free air is required. Compressed Air System's P.O.G.O. More Articles > Plastics. High pressure (30 bar) compressed air is led to the cylinder High pressure (30 bar) compressed air is led to the cylinder o Provides very dryer air with dew point as low as -100°F o Moisture sensitive processes o System exposed to sub-freezing temperatures o Use purge air to recharge desiccant bed so you lose compressed air to this operation: As much as 15% of dryer’s rated flow Need to oversize entire system … For this reason, compressors and compressed air systems are important areas to improve energy efficiency at industrial plants. COMPRESSED AIR SYSTEM By Raj Prabhakar 2. A Systems Approach Helps Rockline Industries Retrofit a Compressed Air System. The trainer notes for each slide provide more detailed information, but it is up to the trainer to decide if and how much of this information is presented also. Taking a systems approach can help eliminate ongoing system problems. The rotor accomplishes this by changing the momentum and pressure of the air. Source: Compressed Air Challenge . Therefore, every effort should be made to reduce the system and compressor pressure to the lowest possible setting. Compressed Air System Performance . Pressure losses in distribution typically are compensated for by higher pressure at the compressor discharge. Similar Images . #145575904 - Steel compressed air filter with on off know with attached silencer.. Add to Likebox #151457117 - Space saver saving seal bag sucking air out , vacuum clothing.. FAD is to be corrected by a factor (273 + t1) / (273 + t2), For practical purposes, the most effective guide in comparing compressor efficiencies is the specific power consumption, i.e. compressed air system arrives at the point of use – Typically takes about 7.5-8 hp to produce 1 hp at point of use . They operate at high speed and generally provide higher throughput than reciprocating compressors. What is Compressed Air System It consists of compressor used to generate high pressure air as per requirement of a TPS. These factors are important when selecting a compressor. For example, a worn out compressor valve can reduce the compressor capacity by as much as 20 percent. As mechanical energy is applied to a gas for compression, the temperature of the gas increases. After compressed air leaves the compression chamber the compressor’s after-cooler reduces the discharge air temperature well below the dew point. Validation Of System For Compressed Air Quality 1. Reciprocating compressors are available in many configurations The four most widely used are horizontal, vertical, horizontal balance-opposed and tandem air-cooled or water-cooled lubricated and non-lubricated may be packaged provide a wide range of pressure and capacity selections.
