The production methods of basic items of monitoring system such as communication configuration, marking database establishment and data recording are introduced in detail, which can be used as a reference for relevant personnel.

    • Solutions to technical problems of centrifuge surge

      When the inlet pressure or flow decreases suddenly and is lower than the allowable operating point, the gas in the compressor will be seriously rotated and separated due to the change of flow, resulting in sudden stall. At this time, the impeller can not effectively increase the gas pressure, resulting in the decrease of outlet pressure.

    • Application of coal mine wastewatersolid-liquid separation

      In the design of coal mine sewage treatment plant, activated sludge process was adopted in the 1980s. Due to the low content of organic matter in sewage, microorganisms can not get the minimum nutrients during operation, so they can not form activated sludge and can not operate.

    • Latest discussionsludge treatment

      Sludge treatment technology includes sludge concentration, dehydration and drying. The existing technology in China is basically sludge thickening and dewatering technology. After sludge thickening and dewatering, the water content of sludge can only be reduced to about 80%, while developed countries are gradually requiring the water content of sludge to be reduced to 20% - 30%. Therefore, efficient and economical sludge treatment technologies, including dehydration and drying technologies, will have a huge market.
