Pathological & Sharp waste disposal equipment
Pathological waste is a category of biohazardous waste. The parent category includes infectious animal bedding/feces, human and/or animal pathogens and disposable items contaminated with human blood or body fluids.
Sharps waste is a form of biomedical waste composed of used "sharps", which includes any device or object used to puncture or lacerate the skin. Sharps waste is classified as biohazardous waste and must be carefully handled.

719 launched full-rotation rudder propeller control system
Recently, the ATCS-1 full-rotation rudder propeller control system developed by 719 Wuhan Haiwang Electromechanical Engineering Technology Co., Ltd. passed the inspection by China Classification Society (CCS) and became the first domestically approved product of CCS type. The successful development of the system marks that 719 Wuhan Haiwang Electromechanical Engineering Technology Co., Ltd. has entered the supporting field of ship full-slewing devices and laid the foundation for future market expansion.
The ship's full-slewing propulsion device developed by 719 is a new type of marine propulsion equipment. The propeller can be rotated 360 degrees in the horizontal plane, omitting the conventional rudder. Compared with ships equipped with ordinary propulsion systems, ships equipped with full-rotation propulsion devices have the functions of forward, reverse, traverse, crushing and in-situ rotation. At this time, the propeller can provide maximum thrust, so the ship operation is more flexible. ,Convenience.
Previously, the full-swing control system has long been monopolized by large foreign companies. There are few domestic researches on related aspects, and the control method still uses the classic PID control. However, the ship is not only subjected to a variety of combined forces such as main thrust, inertial force and viscous force during the voyage, but also encounters various random resistances such as mechanical friction, wind resistance and water flow resistance. Therefore, the conventional control method cannot satisfy the accuracy. Sexuality and stability requirements. In order to meet the needs of the ship market and produce high-performance products, 719 established a professional project team in early 2011, and listed the project as a special topic for independent innovation. The project team abandoned the old method, adopted advanced intelligent control theory based on fuzzy algorithm and neural network algorithm, and cooperated closely with colleges and universities to organize many technical discussions and reviews. At the same time, the Institute actively communicated with CCS to keep abreast of the latest domestic and international related trends in real time, and reported the progress of the development to CCS in a timely manner.
In the production process, the project team pays close attention to the quality of the process. In the design stage, the specific requirements of the relevant plate making process, wiring process and electrical installation process are clearly put forward, and experienced experts are hired to guide. In terms of selection, the project team selected products that have passed the certification of a number of classification societies as the main components, and conducted in-depth comparisons with a number of suppliers, and selected the excellent products to further ensure the performance and quality of the products. The ATCS-1 full-rotation rudder propeller control system not only passed the type approval of CCS, but also passed the electromagnetic compatibility test and environmental test of the national laboratory, and its process manufacturing level has reached the domestic advanced level.
