In Hall E2, many military technologies used in military operations have been developed and transformed into civilian technologies.
Liu Jiaxin, the manager of a manufacturer specializing in the production of parts for CNC machine tools, told the reporter: "We have now transformed the hydraulic device technology used in nuclear submarines into the hydraulic system of ordinary CNC machine tools, which not only greatly improves the safety of the machine tools, but also improves the stability of the machine tools."
This hydraulic component looks like a magnified "screw cap", but this "screw cap" is a key component to ensure the stability of the submarine hydraulic system.
Although Liu Jiaxin could not disclose the specific technical parameters, he said: "With this hydraulic component, the hydraulic balance of the machine tool can almost be perfect."
Liu Jiaxin also introduced an oil vapor volatilization recovery system. The appearance of this system is similar to that of an ordinary refueling gun, except that a component similar to a straw is added to the fuel nozzle.
"Don't underestimate this component. When we refuel normally, the gasoline volatilization rate is about 1%, and the recovery rate of this recovery system can reach more than 90%." Liu Jiaxin said, "For example, if you add 1000 yuan of oil every month, 10 yuan of it will evaporate, which is 120 yuan a year. But you don't know 120 yuan. It happens in the process of refueling, and the gasoline will evaporate with the air. One person will be 120 yuan a year, and the number of a year is quite large in China."
