1) mobile air compressor air compressor easy to move often well-known manufacturers, changing working conditions, load changes (2) mobile air compressor mostly heavy-duty, medium-speed or low speed, most require frequent starting and often withstand shock loads; bad (3) wild environment, humidity, rock dust, coal dust and gas (mostly methane), and some have harmful sulfur gases (sulfur dioxide, hydrogen sulfide), many mobile empty press must take into account fire, explosion, corrosion problems; (4) open mobile air compressor to be able to withstand wind, sun, rain and hot in summer and cold in winter, such as climate change challenge; (5) Due to limited space custom air compressor Which is better? Machine maintenance more difficult, thus requiring mobile air compressor to be durable and to facilitate the maintenance. Second, according to the characteristics of mobile air compressor, lubricating oil made the following requirements: (1) the volume of mobile air compressor and tank volume are small, the amount of lubricating oil is also less loaded, when the oil temperature higher than high, which requires the lubricant has good thermal stability and oxidation resistance. (2) because of the harsh outdoor environments, coal dust, rock dust, more water, lubricating oil contamination of these impurities is inevitable, it is required to have a good anti-rust lubricant, anti-corrosion, anti-emulsifying properties; requirements for lubricants When contaminated, their performance will not be much change, that the sensitivity of the contamination to be small. (3) Mechanical summer and winter outdoor temperature varies greatly, some areas have large temperature difference between day and night, thus requiring the oil viscosity changes with temperature should be small, it is necessary to avoid the temperature is high, the oil viscosity becomes too low to forming a lubricating film, would not achieve the lubrication should play, but also to avoid low temperature viscosity is too high, resulting in starting, running difficult. (4) For some mobile air compressor, particularly in some mechanical prone to fire, explosion of environments, requiring the use of a good anti-flammable lubricant (fire resistant fluid), you can not use flammable mineral oil. (5) requires a lubricant seal better adaptability in order to avoid damage to a seal, the energy-consuming loading after the pressure reaches the desired working pressure compressor, the traditional control methods adopted at its pressure will continue to rise until the unloading pressure . Pressurized process, will occur more heat and noise, and then causing power loss. On the other hand, high-pressure gas before entering the pneumatic components, the pressure demand pressure through the valve, the same energy in the process. 2, unloading energy consumption when the pressure reaches unloaded, active open air compressor unloading valve, Xianyang compressor motor idling, forming a large energy consumption. Power compressor unloading of about 30% to 50% at full load, showing the traditional air compressor has a significant saving space. 3, the frequency of the main motor launch in spite of the impact of current large selection of decompression start, but the starting current is still great, big impact on the grid, as well as easy to form a grid instability affecting the operation of other electrical equipment safety. 4, the pressure instability, low degree of automation of traditional compressor bottom degree of automation, the output pressure of conditioning is to rely on the loading and unloading valves, control valve manipulation to complete, conditioning slow shake, low accuracy, the output pressure instability. 5, a large amount of air compressor equipment maintenance Frequency launch current, up to 5-8 times the rated current, the operation mode determines the loading and unloading valve must repeat the action, parts easy to aging, the frequency at high speed, bearing wear and maintenance of large equipment . 6, noisy-frequency high-speed operation continues beyond the rated working pressure of the pressure required, repeated loading, unloading, directly resulting in the power frequency operation.
