Tongmao linear motor applications in the aircraft carrier, linear motor is a direct conversion of electrical energy into linear motion mechanical energy transmission. It can save a lot of intermediate transmission mechanism, speed up the system to reflect the speed and improve the system accuracy, so it has been widely used. Linear motor not only used in industrial manufacturing, we can see the ship in the figure.
Water jet propulsion device is a new type of special power device, and the common propulsion method is different from the thrust of water jet propulsion pump is by pushing the reaction of water flow to obtain and through the control of the rudder and the rudder equipment distribution And change the jet direction to achieve the operation of the ship. In the gliders, piercing boats, hydrofoils, hovercraft, etc., the high-speed vessels have been applied. Adopting water-jet propulsion is a major technological trend on the road of mute, high-speed and high-mobility naval equipment. Large flow of ultra-quiet linear drive seawater pump can be applied to the water jet propulsion device to promote the development of high-speed ultra-quiet torpedo, high-speed ultra-quiet anchored mines, quiet submarines can also be used for ultra-quiet water jet propulsion power Various surface ships, such as water-jet minesweeper, water-jet booster boats and amphibious landing warships. The development of linear motor-driven hydraulic piston pump is a multidisciplinary technical problem involving fluid transmission and control, optimization design and manufacturing, modern control, tribology and other disciplines. The integrated application of hydraulic and linear motor technology, with Strong discipline innovative, forward-looking and broad application development prospects.
At present, there are not many domestic units capable of independently developing linear motors. Only a few manufacturers independently developed linear motor platforms and drivers. For example, we know that the speed planning, current loop and servo loop control strategy of linear motor are important factors affecting the stable output of direct-drive plunger pump. This is a technical difficulty in the current technical research of direct-drive pump. Even so, from the current trend of development, the linear drive system has shown great vitality as an ideal feed drive. The linear drive reciprocating pump, as a new type of marine pump, also shows its unique The advantages of the ship for the future development of the pump pointed out the direction.
