一、Features: 
1. Simple structure and convenient maintenance;
2. Significant energy saving effect, reducing the operating cost of the equipment;
3. There are two forms of packing seal and mechanical seal which are suitable for different shaft seal requirements. The packing box leakage coupling screw hole can deliver the dripping cooling liquid to the designated place to meeting the environmental requirements
4. There is no contact operation of the rotating parts of the compressor in the working chamber; the axial and radial loads are borne by different bearings respectively. The operation is stable, safe and reliable;
5. There are inspection holes on the side cover. As long as the inspection cover plate is opened, corrosion and scaling in the pump can be observed to facilitate equipment maintenance.
6. 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, especially suitable for the extraction and pressing of inflammable and explosive gases, and gas and non-granular dust is allowed in the gas.
7. When the flow components of the compressor are made of corrosion-resistant materials, corrosive gases or corrosive liquids can be sucked as working fluids; The purchase cost can be reduced when ordinary materials are used and lined with macromolecular protective layer.
