Surge may occur as long as the centrifugal compressor is running. This phenomenon can only effectively control and reduce the frequency of surge, but cannot be fundamentally eliminated. Therefore, correctly judging the surge phenomenon of centrifugal compressors can eliminate the surge area in time, which is of great significance to the safe, stable and long-term operation of the compressor. During production and operation, strong vibrations sometimes occur suddenly, and the flow and pressure of the gas medium also pulsate greatly, accompanied by periodic dull cries and strong whistling noises caused by air flow fluctuations in the pipe network. This phenomenon is commonly known as is the surge condition of the compressor. The compressor cannot operate under surge conditions for a long time. Once the compressor enters the surge condition, the operator should immediately take adjustment measures to reduce the outlet pressure or increase the inlet flow to make the compressor operating point out of the surge zone to achieve stable operation of the compressor. The surge phenomenon of centrifugal compressors is the most common problem in the UK in 2018. First discover and draw people's attention. The occurrence of surge phenomenon depends on the characteristic curve of the pipe network and the characteristic curve of the centrifugal compressor. The reason for the formation of surge is the periodic alternation of reverse flow and air supply. In addition, it should be noted that it is best to set the fresh air inlet and hot air outlet on two opposite walls. The purpose of this is also to prevent the exhausted hot air from entering the air inlet again and causing an air flow short circuit. It is best to set up a dust mesh at the fresh air inlet to prevent more dust or catkins and other debris from entering the air compressor room. It is best to set up a rainproof cover at the hot air outlet to prevent rainwater from flowing into the heat exhaust duct. When the single exhaust volume is equal to or greater than the compressed air station and the total installed capacity is equal to or greater than //, lifting equipment for maintenance should be installed, and its lifting capacity should be determined according to the heaviest component of the air compressor unit. Reserve passages and maintenance space. According to the requirements of the "Compressed Air Station Design Code", the width of the passage between the air compressor unit and the wall is based on the exhaust volume. . Matters needing attention when piping compressed air pipelines. When piping main pipelines, the pipelines must have an inclination of ~ to facilitate the discharge of condensed water in the pipelines. The pressure drop in the piping pipeline must not exceed % of the operating pressure of the air compressor, so it is best to use a pipeline larger than the design value when piping
