一、Features: 
1. Advanced design technology, precision processing equipment, elaborate manufacturing and processing, and strict quality control ensure the comprehensive performance of products. It is compatible with that flow law, reliable operation, long service life, high operation efficiency and multiple driving modes.
2. Automatic control can be realized, either on-site control or remote DCS control.
3. Obvious individualized features, safe operation, compact structure and energy-saving effect significantly reduce the operating cost of the equipment.
4. Due to the use of water or other liquid as working liquid, it is possible to carry away the heat of compression, the working process is close to isothermal compression, it is especially suitable for the extraction and pressure of combustible and explosive gas decomposition gas (such as acetylene, carbon sulfide, hydrogen sulfide, etc.), and the gas is allowed to contain water vapor and non-granular dust;
5. Because the compression medium is not in direct contact with the pump body when the over-current parts of the compressor adopt corrosion-resistant materials or spray anticorrosion coating, they can be used to suck corrosive gas or use corrosive liquid as working liquid of the compressor. The complete unit of 2BW7 liquid-ring compressors is also particularly suitable for compressing highly corrosive gases such as chlorine. In this case, a liquid that does not interact with the compressed gas can be selected as the sealing fluid, for example, concentrated sulfuric acid is used when chlorine is compressed.
6. Simple structure, easy manufacturing, easy operation, convenient installation, less vulnerable parts and low noise.
