6RT-flex50B diesel engine is a new intelligent two-stroke marine low-speed high-power diesel engine developed and manufactured by the company with the advanced patented technology of WATTSILA. It is the first model in China and the world. The first machine exported the machine and installed it for the 50,000-ton crude oil wheel built by the RISANIAGO Shipbuilding Company of Argentina for the Venezuelan oil company. At present, the factory is holding 10 orders of the first batch of RT-flex50B diesel engines. This intelligent diesel engine is suitable for a variety of ship types, including a new generation of handy and Panamax bulk carriers, large oil tankers, container ships and medium-sized refrigerated ships. Broad market application prospects.
In recent years, Yichang Ship Chai adheres to the introduction, digestion, absorption and technological innovation. It is oriented to market demand and aims at the development direction of high-tech low-speed high-power diesel engines, giving full play to the existing equipment and technical advantages of the plant, focusing on new high efficiency and low efficiency. The research and development of key manufacturing technologies for marine diesel engines has broken through its important core technologies, cultivating core products and core manufacturing technologies, gradually realizing the industrial production of low-speed diesel engines, improving the competitiveness of the international and domestic markets, and achieving the technological level and economic strength of enterprises. Leapfrog development.
In order to ensure that the first 6RT-flex50B diesel engine mainframe is delivered as planned, Yichang Shipai has carefully organized the whole plant, and worked hard to carry out R&D technical preparation and blueprint conversion design according to the supply contract and supply technical conditions signed with the users. , parts processing and assembly process design. The WARTSILA technical experts confirmed that the components installed in the RT-flex50B intelligent diesel engine met the original design technical requirements. From the test data of the bench test, the design structure, strength and performance of the first RT-flex50B intelligent diesel engine fully met the requirements. And meet the requirements of the LR classification society. Shipyards, shipowners, ship design units and classification societies have unanimously affirmed that their manufacturing processes are advanced in technology and quality.
The forced circulation pump does not rely on the centrifugal force of the impeller to the liquid, but uses the thrust of the rotating impeller blades to make the sent liquid flow along the direction of the pump axis. When the pump shaft is driven by the motor to rotate, because the blade has a certain helix angle with the axis of the pump shaft, a thrust (or lift) is generated on the liquid, and the liquid is pushed out and discharged along the discharge pipe. When the liquid is pushed out, a partial vacuum is formed at the original position, and the liquid outside will be sucked into the impeller along the inlet pipe under the action of atmospheric pressure. As long as the impeller keeps rotating, the pump can continuously suck in and discharge liquid. The forced circulation pump works by using the horizontal thrust along the direction of the pump axis generated by the rotation of the impeller, so it is also called a horizontal axial flow pump. Mainly used in the evaporation of diaphragm method caustic soda, phosphoric acid, vacuum salt production, lactic acid, calcium lactate, alumina, titanium dioxide, calcium chloride, ammonium chloride, sodium chlorate, sugar, molten salt, paper, waste water and other industries. Concentration and cooling, in order to improve the production capacity of the equipment, increase the heat transfer coefficient of the heat exchanger for forced circulation. Therefore, it can also be called an axial flow evaporative circulation pump.
