Weihai Zhide Vacuum Technology Co., Ltd. has been devoting itself to the research of the core components of the screw vacuum pump and has successfully developed a new type of dry screw vacuum pump. It replaces the expensive foreign equipment with a domestic lathe to produce a screw rotor. It not only saves energy by 30%, but also has easy equipment. With less damage, higher vacuum, higher pumping speed, and longer service life, it can replace imported products in more than 100 fields such as metallurgy, electronics, petrochemicals, and aerospace. The picture shows a corner of the production workshop.
