He has made significant contributions to the field of engineering, particularly in the development of advanced vacuum pump technologies. With a total of 5 patents to his name, Fang's work exemplifies innovation and practical application in industrial technology.

Latest Patents

One of his latest inventions is the Multi-stage Vacuum Pump. This innovative design includes a plurality of casings connected in series, each defining a respective compression chamber. The pump features partition plates set between each two casings, allowing compressed air to pass through air paths formed in the partition plates for further compression. This design minimizes the outer diameter and volume of the pump, effectively reducing both weight and manufacturing costs.

Another significant invention is the Asymmetric Double Screw Rotor Assembly. This assembly consists of two asymmetric screw rotors that mesh together within a casing equipped with an inlet and an outlet. The spiral threads of the screw rotors maintain a uniform pitch, while the diameters of the rotors are designed to gradually change from the inlet to the outlet. This unique configuration allows for a reduction in the volume of air chambers as the air moves through the assembly, enhancing efficiency.
