■ overview of esdp dry screw vacuum pump
the ultimate pressure is completely free of oil and water.
esdp dry screw vacuum pump uses a unique screw rotor profile, which saves 30% of power, has low exhaust temperature and stable process. dry screw pump products are suitable for vacuum processes in various fields, and also maintain zui's excellent vacuum efficiency and durability.
esdp series does not use oil and water. it is operated in a variable compression mode. it is a mixed process of water vapor and liquid. it is very suitable for various vacuum processes such as drying, solvent recovery, chemical industry, pharmacy, plastics, etc.
■application scope of esdp dry screw pump
●the application of esdp series in semiconductor synthesis and liquid crystal production mainly includes semiconductor plasma enhanced vapor deposition (pecvd) and reactive ion etching (rie), liquid crystal production etching process and cvd process for tft screen plasma production. this process requires a backflow of 0 to protect the workpiece from contamination.
● in petrochemical industry, condensable gas, toxic gas, corrosive gas or gas containing dust is mainly extracted.
●the pharmaceutical industry is used for vacuum drying of drugs, recovery of drug intermediates, recovery of gaseous disinfectants, provision of clean and sterile conditions for artificial organs, etc.
●in chemical industry, it is used for vacuum distillation and solvent extraction and recovery, such as extraction and recovery of acetone, polyol and other processes.
●industrial exhaust; centralized vacuum processing system
●mixing process of extruder and exhaust process of plate
●mixed resin deodorization process; used in fatty acid production to eliminate water pollution and blockage in injectors.
●the food industry is used for spice, essence concentration, food packaging, etc.
