1 results about "Injector" patented technology

A steam injector is typically used to deliver cold water to a boiler against its own pressure using its own live or exhaust steam, replacing any mechanical pump. This was the purpose for which it was originally invented in 1858 by Henri Giffard. Its operation was from the start intriguing since it seemed paradoxical, almost like perpetual motion, but its operation was later explained using thermodynamics. Other types of injector may use other pressurised motive fluids such as air.

InactiveCN113246425AGuaranteed sterilityIncrease the stationDomestic articlesProcess engineeringIndustrial engineering
The invention belongs to the technical field of pharmaceutical equipment, and particularly relates to a needle pre-filling continuous production process for plastic medicine bottles. The process comprises the following steps of (1) tube blank extrusion, (2) tube blank transfer, (3) needle adding and bottle making, (4) filling, (5) injector piston adding and sealing, and (6) blanking. The needle pre-filling continuous production process for the plastic medicine bottles is a whole systematic process and covers a process from raw material conveying to final product conveying, compared with a traditional BFS process, a packaging process is characterized in that an injection needle adding station and an injector piston adding station are added and A-level air shower protection is added in a whole transferring process, functions of equipment are greatly increased, the quality of produced products is higher, the sterile safety of the products is better, and the problem of pollution possibly existing in a process from production to injection of medicines is fundamentally solved.
