Recently, the first domestic fishing boats with dual single propeller double speed integrated power test in heavy diesel station installation after nearly two weeks and machine test, the performance data and indicators fully meet the design requirements, marking the project from the Chai heavy led, which lasted two years developed was a complete success, which means that there are the dynamic selection is more practical and more economical, the combination of a variety of domestic offshore fishing vessels in the future, to create a precedent for technological progress of fishing machine industry.
Hechai heavy industries first domestic fishing integration was very successful with two single screw double power ratio
It is reported that single oar power integration refers to the operation by two engine driven by a double input and double speed gear, output, single propeller, through the control of the control system, realize the rapid conversion of fast navigation and low speed and high load work. The main technical difficulties of integrated power control is to control the diesel engine gear box and main synchronous control system of the system effectively, establish logical relationship clear, so that the three high together, finally to two conditions of the integrated power can be safe and reliable in the fishing machine often used to switch at the same time, can effectively protect the fishing boats in a bad weather or a machine fault situation, fast safe or smooth return.
Dual engine single screw double speed ratio power integration is mainly used in domestic inshore fishing vessels. In recent years, with the improvement of the discharge standard of fishing machine and the progress of all kinds of technologies, the new fishing boats are showing a tendency to build more and more. However, as the "heart" of fishing vessels, there is a common situation that the operating characteristics of fishing vessels can not match the high efficiency. Go to fishing in the fishing ground, time is efficiency, high speed navigation; stopping net fishing, need low speed high torque tension (fishing) network, the two kinds of speed and load of the extreme conditions, easy to damage the overall performance, diesel engine malfunction, and the choice of power range is particularly wide, the price is too expensive the price is very low. Fishermen generally appeal: we need to fit their own fishing boats heart".
To change this situation, hechai heavy industries and agents to issue several in-depth communication, to market the first line of research, users listen to opinions and suggestions, combined with the advanced achievements in science and technology, decided to gear box factory jointly developed by single screw double integrated power ratio. The integrated power mainly for gillnetting ship design quantity, and under certain conditions can be extended to other ship types (Seine fishing boats, trawlers, etc.), so get the attention of industry.
Fishing boats with dual single propeller double speed power successfully integrated development, not only for vessel construction reduces the cost, solve the fishing needs, but also a huge potential market, will have a profound impact on the expansion of the application hechai heavy fishing machine products in the market.
