Audited Supplier Chongqing Gohi Marine Equipment Co., Ltd. is a professional manufacturer of ship propellers. Our workshop covers an area of over 20000 square meters. The products include propeller accessories such as fixed pitch propellers, controllable pitch propeller blades, and propeller hubs. The company has sound propeller manufacturing equipment and a precise material performance testing system, which can produce various types of marine propellers and supporting shaft products with a finished weight of 30 tons and a diameter of less than 8 meters. The product quality has passed the ISO9001 system certification and has been recognized by major national classification societies such as CCS in China, BV in France, ABS in the United States, KR in South Korea, and RINA in Italy.
Marine ship boat propeller is a device that converts the engine's rotational power into propulsion by rotating the blades in air or water. It can have two or more blades connected to the hub, and the aft side of the blades is a helical surface or a type of propeller that approximates a helical surface.
The propeller blades of a ship refer to the blades that can rotate in the water and are a partial device that converts the engine's rotational power into propulsion. There may be two or more blades connected to the hub, and the aft side of the blades is a helical surface or similar to a helical surface, which is a type of marine thruster.
The variation process of the tension of the spiral blade with the rotational speed is as follows: due to the increase in engine output power, the propeller speed (tangential speed) rapidly increases to a certain value, and the propeller tension increases. In the development of ship technology, the design and research of spiral propeller blades have been done much more than any other professional field, transitioning from empirical methods to digital design, and then applying computer technology to optimize the design of spiral propeller blades. The blade angle of a propeller should gradually increase from the tip to the root according to a certain pattern.
