Vacuum pump for coal industry

Coalbed methane is generally adsorbed on the coal seam, which has to go through three production processes: drainage, depressurization and gas production. The vacuum pumps used in coal mines are from SZ series of Soviet Union to SK Series independently developed by our country, and then to the leading position today. 2be series water ring vacuum pumps adopt the most advanced foreign technology, and each change is toward the direction of energy saving and reliability. For example, the SZ-4 vacuum pump in the 1960s and 1970s had a maximum gas volume of 1700m3 / h, and its efficiency was only 20% - 30%. Sk-85a, the largest in the 1980s, had a gas volume of 5100m3 / h and an efficiency of 30% - 40%. However, the 2BE3 series water ring vacuum pump / compressor with foreign advanced technology, developed and produced through joint venture and cooperation, has a gas volume of 60000m3 / h, an efficiency of 45% - 60% or more, and operates more effectively Reliable.

Safety, complete set, automation and high reliability are the basic requirements for vacuum pump in coal industry. Traditionally, vacuum pumps are mainly used by equipment manufacturers, such as pre separators, anti backfire devices, gas separators, electric control, sensors, instruments, etc. are configured by the coal mining enterprises themselves. This not only reflects the low degree of complete set, but also leads to the low efficiency of main equipment due to the incongruity of configuration, and even the equipment can not work normally due to professional differences Make.

Therefore, complete equipment is the development direction of vacuum equipment in coal industry. In the coal industry, the vacuum pump, whether used for gas drainage, transportation, coal washing, chemical industry, drying and well production, has a unique use environment. However, China's coal mines are widely distributed, with different climatic and geographical conditions. In view of these particularities, providing personalized vacuum equipment is also the direction of product development in vacuum equipment manufacturing industry. Vacuum industry manufacturers are committed to the research and development of safety, energy saving, environmental protection, chemical and other equipment in China's coal industry, and have developed a set of mechanical, electrical and instrument integrated vacuum unit, equipped with complete steam water separator, circulating heat exchanger, online measurement and control instrument, automatic control system, valve components, etc.
