Latest Patents

Naya's recent patents include groundbreaking inventions aimed at enhancing the functionality of screw type vacuum pumps. His first notable patent is the "Screw Type Vacuum Pump with Introduced Inert Gas." This innovative device features a pump casing equipped with a suction inlet and discharge outlet. Inside this casing, a pair of rotors mesh together, rotating in synchronization to create a negative pressure condition in a reaction vessel. During operation, inert gas is introduced into the compression working chamber, where it undergoes adiabatic compression, generating heat that helps in heating the rotors and casing wall. This method effectively reduces the partial pressure of the process gas, preventing side reaction products from accumulating on key components.

Another significant patent by Naya is the "Screw Vacuum Pump Unit," which provides a design where both the screw block and driving motor are mounted on one side of the casing of a speed change gear. This configuration allows for the male and female rotors’ axes to be arranged in vertical adjacency within a perpendicular virtual plane, facilitating easier maintenance. The innovative layout of suction and discharge ports enhances the operational efficiency and user accessibility of the vacuum pump unit.
