C. quality gas oil content per unit volume of air contained in the oil (including oil droplets, suspended particulates, oil vapors) air compressor manufacturers offer, converted to absolute pressure 0.1MPa, temperature 20 ℃ and a relative humidity of 65% values ??under standard atmospheric conditions, the unit mg / m3. D.PPM a representation symbol trace substances in the mixture in an amount, referring to the parts per million or parts per million (by weight and volume ratio PPMw PPMv). Usually we are talking PPM weight ratio. (1kg millionth of a milligram) 1PPMw = 1.2mg / m3 (PA = 0.1MPa, t = 20 ℃, φ = 65%) E. Dew point temperature in the lower-pressure wet air cooling, air originally not containing saturated steam into saturated steam temperature, or, when the air temperature is lowered to the dew point, the air is not saturated water vapor contained in the original reached saturation (ie water vapor began large-scale air compressor production of liquefied manufacturers, liquids condense out). Volume flow and volume flow of the compressor air consumption of the similarities and differences of pneumatic components compressor air consumption means free flow of air, pneumatic components refers to the flow of air under compression. The conversion formula: Q = Q since pressure * ε m3 / min ε = P row (absolute pressure) / P Suction (absolute pressure) = (P row (gauge) +1.033) /1.033 = (P 'row (gauge pressure ) +0.1013) /0.1013 where P row (gauge) - Unit kg / cm2 P 'row (gauge) - Unit MPa proper care and maintenance of air compressor is the only way to prolong the life of the air compressor air compressor production manufacturers, so before doing repair and maintenance of what we need to do? 1. Cut off the mains and put up signs on the power switch. 2. Shut off the gas supply system shut-off valve to prevent compressed air to flow back is a partial overhaul. Never rely on a one-way valve to isolate the gas supply system. Pressure emptying system. 3. Open the manual vent valve. Adhere to the vent valve is open. 4, water-cooled machine. Close the water supply system is necessary to release water pipeline pressure. To prevent burns, burns. 5, to ensure that compressor is cooled down. 6, wipe the surface oil marks, water stains to prevent slipping. Fault diagnosis and control of high-power air compressor to a systematic, reliable, real-time, online, scalability and economy principle and to optimize the system to the maximum extent possible the automatic adjustment compressor condition compressor manufacturers build, strong self-diagnose power of the computer, increase the fault tolerance of the system. Intelligent diagnostic aid modernization, strengthening human involvement troubleshooting analysis and processing. According to the status of enterprises, enhance economic efficiency and benefits for the purpose of worship ancestors, the modern concept of fault diagnosis process through to the heart of every enterprise employee! Qin Wei Air (map), air compressor manufacturers, air compressor manufacturers definite by the Xianyang Qin Wei empty press Limited. Xianyang Qin Wei Compressor Co. (www.xykyj.cn/) to provide "air compressor and accessories, general machinery parts," such as business, the company has "Wei Qin brand, Coatler card (C?te children)" and other brands. Focus on compression, separation equipment and other industries, have higher visibility in Xianyang. Welcomes inquiries, contact: Liu.
