2 harmonic electromagnetic noise and vibration ordinary asynchronous motor with inverter power supply, vibration and noise cause by the electromagnetic, mechanical, ventilation and other factors caused becomes more complicated. Frequency power supply is the AC mains through the AC → DC → AC conversion, pure sine wave output, output frequency and voltage within a certain range is adjustable. It is different for variable speed controller motor speed with oil-free air compressor manufacturers, but also from ordinary AC power supply. Ideal frequency AC power is characterized by stability, voltage stability, resistance to zero, the voltage waveform is a pure sine wave (no distortion). Very close to the ideal frequency AC power supply, and therefore, more and more advanced countries will be used as a standard power supply power inverter compressor manufacturers supply in order to provide the best use of electrical power environment air compressor manufacturer price easy and objective assessment of technical performance appliances. There are two major power inverter types: linear amplification type and SPWM switch type. Wherein the intrinsic spatial harmonics each time time harmonic electromagnetic motor section containing interfere with each other to form a variety of electromagnetic exciting force. When the natural frequency of the electromagnetic force wave frequency and the motor body of the same or close, it will have a resonance phenomenon, thereby increasing the noise. Since the motor, wide frequency range compressor manufacturer, speed range changes, the frequency of various electromagnetic force wave is difficult to avoid the natural vibration frequency of each member of the motor. 8, clean moisture separator moisture separator structure similar to the oil and gas tanks, air intake against the wall design, so the formation of a centrifugal force, the weight factor due to water and gas, compressed air can be effectively separated in the water. Moisture separator cleaning: open the moisture separator cover, you can use detergent immersion cleaning. 9, correcting all the parameters of all the above components and dry after cleaning the air compressor to start the installation, all components attached to the compressor should again check for omissions and clean during installation tools and other items used. Wash load reduction valve (inlet valve) bis (1) Cleaning: as intake valves dirt more serious, then replace it with a new cleaning cleaning agent, the cleaning process to wash the dirt should be washed after much cleaner parts parts. Cleaned parts rinsed again with fresh water to prevent corrosion and shorten the service life of components, the components washed with water should be placed in a clean dry place to avoid iron rusting parts. Should purge valve and place the body in contact with the valve in note smoothness of the surface, and should be cleaned, replace it if necessary, otherwise it will cause will have when the compressor can not start with a load (a large plant with a load start start phenomenon). (2) Installation components: Component installation removed anti-press steps. Should make is when you install components, component location and activity of installed seals should be coated with an appropriate amount of oil can install seals better, more flexible moving parts. Note: Due to the unloader valve more parts, if not sure to remember the location of each part can be cleaned after each split a component mounted on the component, but members do not install to the body, until all the parts are cleaned then assembled together to the valve body. (3) unloader valve aside to complete the cleaning process to be loaded into the compressor.
