At present, the
development of various vacuum pumps is more and more affected by vacuum
applications. The general vacuum system can not meet the requirements of clean
and oil-free corrosion resistance. Therefore, in recent years, the market demand
for dry vacuum pumps is very large, and the vacuum products have been upgraded.
A large number of oil-free vacuum systems have been replaced by oil-free and
clean vacuum systems.
Almost every large vacuum company abroad produces
various types of dry vacuum pumps. Screw vacuum pump is a kind of non-contact
dry pump, which appeared in the early 1990s. It occupies the market with the
advantages of wide pumping speed range, simple and compact structure, non
friction of pumping cavity components, long service life, low energy consumption
and no oil pollution. However, most of its manufacturing technology is mastered
by foreign countries, and China is still in its infancy. The market has a strong
demand for dry pump

Present situation of dry vacuum
pump
Due to its superior performance, dry screw vacuum pump has become the
preferred vacuum equipment in microelectronics, semiconductor, pharmaceutical,
precision processing and other industries in Europe, America and Japan. On the
basis of screw compressor, Japan has developed the multi head rotor line of
vacuum pump and put it into the market for a long time. Several German vacuum
equipment companies have gradually developed equal pitch and variable pitch
rotor profiles, and have done a lot of research on rotor and body cooling.
