Hechai Heavy Industry Co., Ltd. Developed the first domestic fishing boat with dual-machine single-blade two-speed ratio power integration was a complete success

Recently, the first domestic fishing boat with dual-machine single-blade two-speed specific power integration in the Hechai Heavy Industry Test Station after nearly two weeks of installation and commissioning and parallel test, the performance and data indicators fully meet the design requirements, marking the river The project, which was led by heavy industry and developed over two years, was a complete success. It also means that the domestic offshore fishing vessels will have more practical, economical and multi-combination power selection, which is the first step for the technological advancement of the fishing machine industry.

It is reported that the dual-machine single-blade power integration refers to the operation input of two engines, which drives a double-double-speed gearbox output, matches the single propeller, and realizes the rapid conversion of fast navigation and low-speed and heavy-duty work through the control of the control system. The technical difficulty of this power integration is mainly to control the diesel engine, the control of the gearbox and the main control system of the system to establish a clear logical relationship, so that the three can be efficiently integrated, and finally the power integration can be safe. It can reliably switch between the two working conditions frequently used by the fishing machine, and at the same time, it can effectively ensure the fast and safe hedging or smooth return of the fishing boat in the case of bad sea conditions or a machine failure.
The dual-machine single-blade two-speed ratio power integration mainly serves domestic offshore fishing vessels. In recent years, with the improvement of fishing machine emission standards and the advancement of various technologies, new fishing vessels have shown a trend of increasing construction and increasing scientific and technological content. However, as the power system of the "heart" of the fishing boat, there is a general situation that the fishing boat operating characteristics cannot be matched. When the fishing boat goes to the fishery, the time is efficiency and needs high-speed navigation. When the fishing net is used for fishing, low-speed and high-torque pulling (fishing) nets are needed. These two kinds of extreme conditions of speed and load are very easy to damage the overall performance of the diesel engine. The fault is caused, and the power with a particularly wide power range is selected, the price is too expensive, and the cost performance is extremely low. Fishermen generally appeal: we need a "heart" that fits the fishing boat itself.
In order to completely change this situation, Hechai Heavy Industry and its agents have repeatedly communicated on this issue, and went to the first line of market research, listened to the opinions and suggestions of users, combined with advanced scientific and technological achievements, and decided to jointly develop the joint gearbox factory. The single-blade two-speed is more integrated than the power. The power integration is mainly designed for a large number of spunlace ship types, and can be extended to other ship types (smuggling nets, trawlers, etc.) under certain conditions, so it has received great attention from the industry.
The successful development of the dual-speed single-speed two-speed power integration of fishing vessels not only reduces the cost for the construction of fishing boats, but also solves the needs of fishing vessels, and has great market potential. It will have far-reaching effects on expanding the application of Hechai Heavy Industry products in the fishing machine market. influences.
