Marine jet pump propulsion

Marine underwater propulsion is a vacuum jet propulsion device that uses river water or seawater to transmit energy and thrust. The water flow with a certain pressure is sprayed through the nozzles symmetrically and evenly distributed to a certain side inclination, and converges on a focus. Due to the extremely high velocity of jet water, it is a way of ship propulsion that converts pressure energy into velocity energy.

Years of design practice of marine jet pump propulsion have proved that only by mastering the initiative of development, when the required vacuum degree is not too high, a water jet with a certain pressure of water as the working fluid can be used to generate vacuum. The speed of the water jet is often around 12-25m/s. It belongs to rough vacuum equipment. Because the water jet has the dual functions of generating vacuum and condensing steam, it is possible to maintain strategic concentration in the face of wind and waves, face difficulties and climb over hurdles, so as to break new ground and open up new situations.

Marine jet pump propulsion electrical control system inverter-driven stepless control solution, ingenious design, high mechanical efficiency, small size, combining the advantages of driven positive displacement pump and vane pump, marine propulsion in intelligent battery management, its It has a product line of 200KVA, the height of the power module is only 3U, the system host is equipped with a 10.4-inch color large touch LCD display, the core power device adopts an integrated package IGBT module, and has a hot-swappable static bypass monitoring module, a powerful remote network management solution, Quality inspectors are the "pillars" of workshops and quality control, and the "leaders" of career development. The ejector can spray water almost continuously, with high water spraying efficiency and large power per unit volume; it has a wide range of adaptability and can be used as warship propellers, submarine propellers, speedboat propellers, general passenger and freighter propellers, etc., and can also be used for civil use. The propeller of fishing boats and cruise ships; at the same time, it can also be used as a common water pump; if it is used in reverse, it can be used as a water turbine in hydropower generation; at the same time, after a little improvement, including the addition of a one-way valve, it can be used as an air extractor and For compressors. It is widely used in winches and crane ships, dredger electric propulsion. Inverter drive has the advantages of stepless control, low maintenance requirements, low starting current control and stable operation.
