C. quality gas oil content per unit volume of air contained in the oil (including oil droplets, suspended particulates, oil vapors), the conversion to the absolute value of pressure 0.1MPa 20 ℃ temperature and relative humidity of 65% of the standard atmospheric conditions, 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 (ie water vapor did not start to become saturated steam saturated steam temperature, or, when the air temperature drops to the dew point of the air compressor manufacturer of customized, originally contained in the air is not saturated water vapor containing reached saturation liquefaction, condense out liquid). Volume flow and volume flow of the compressor air consumption of the similarities and differences of pneumatic components compressor means free flow of air compressor manufacturer, air consumption 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, then do Before servicing and maintenance 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. Also note the following: 1, not the machine down. It can be carried out repair and maintenance work, because the machine's automatic control system will automatically start the air compressor at all times. 2, poor maintenance of home for not only affect the normal operation of the unit, serious cases may affect the safety of the operator. 3, when the compressor is running or pressurized. Do not arbitrarily mounting nuts, filler plug, and other parts of large air compressor manufacturer, this can also cause unforeseen damage to the compressor. 4. Never use gasoline or kerosene solvent can then clean the air filter or other components. You should use appropriate safety solvent for cleaning of air compressor and its accessories. In summary, before you repair and maintenance of air compressor must be good attention to these aspects, though it seems difficult but it is important to detail.
