The spring river tide rises level with the sea, As the bright moon over the ocean seems to rise with the tides. First the early tide ebbs away, then the evening tide returns— In a single month, the tides flow and ebb sixty times in their cycle. Tidal phenomena, which have inspired poets to express their emotions through nature's beauty, were already well-known and studied by people in ancient times. Today, however, alongside the energy crises triggered by traditional sources, issues like global warming and environmental pollution have emerged as pressing concerns. People have no choice but to consider renewable, green, and clean new energy sources, and tidal energy, as one such emerging resource, is also attracting increasing attention.
Tidal energy That is, tidal power generation, It is a clean, renewable, and predictable energy source. The principle behind tidal power generation is similar to that of conventional hydropower—harnessing the potential energy created by the difference in water levels during the rise and fall of tides to generate electricity. Because seawater is 832 times denser than air, under the same power output conditions, tidal energy turbines can be significantly smaller compared to wind turbines, while still allowing for a more compact arrangement.
As a veteran domestic manufacturer of marine gearboxes, Hangchi has an inseparable bond with the sea. Its forward-thinking and proactive spirit drives Hangchi to strive beyond the rewards offered by traditional markets. 2014 In that year, the astute team at Hangchi already sensed the business opportunity in tidal power gearboxes. After more than a year of joint development—and incorporating several world-leading technologies such as multi-planetary flexible shafts, outer-ring-less bearings, and differential分流 mechanisms—Hangchi finally succeeded in 2015. At the beginning of the year, we successfully secured an order for tidal gearboxes. Naturally, the tidal gearbox has become a key member of Hangzhou Gear’s new energy industry.
Since the main equipment for tidal power generation operates underwater, it needs to achieve 6 Maintenance-free for the year, 20 High demands for a 10-year service life. The precision requirements for machining, assembly, and product testing of tidal gearbox components are exceptionally stringent, making the overall process quite challenging. Thanks to the relentless efforts of dedicated personnel, the first two gearboxes were successfully completed in 2015. The project was successfully completed in early December. Since then, a series of tests have been carried out sequentially, including no-load tests on the gearbox, load tests, deceleration tests, overload and overspeed tests, no-load overspeed tests, and air-tightness tests, among others. Throughout the testing process, technicians and operators worked closely together, pooling their expertise and creativity. Leveraging their reliable technology and extensive experience, they overcame numerous challenges. By the end of 2015, the large-megawatt tidal power gearbox had been successfully prototype-built, passed inspection, and was delivered to the customer for installation and commissioning. Currently, the project has entered the full-machine testing phase.
The tidal gearbox recently undertaken by Hangzhou Gear is the largest single-unit tidal power gearbox globally to date, with a generating capacity of 1.5 MW. , which will be applied in the first-phase demonstration project of the world's largest tidal energy project currently underway. This project is the flagship initiative of a global leader in the tidal power industry and is located in Europe; the entire project will ultimately achieve a total installed capacity of 400 MW. Will be 175,000 Household European families will receive electricity supplies, with the first phase set to begin delivering power to the grid in 2016.
Tidal power generation has yet to see significant development domestically, but it has already begun initial trials in Europe and North America. The tidal gearbox is another rising star in the new energy sector for Hangzhou Gear, following its success with gearboxes for new-energy vehicles and wind turbines. The successful delivery of the tidal gearbox marks a crucial milestone on Hangzhou Gear's journey toward transformation and upgrading, firmly establishing the company as a true "trailblazer" in the industry. Leveraging its expertise in wind turbine gearboxes, Hangzhou Gear has actively expanded into other clean-energy markets—and early results are already emerging. The delivered prototype tidal gearbox, along with the ongoing nuclear power project, clearly demonstrate the company's robust R&D capabilities, rigorous quality management, exceptional craftsmanship, and cutting-edge manufacturing prowess. Moreover, the successful export of the tidal gearbox lays a solid foundation for similar new-energy products to go global in the future. As an emerging industry, the new energy sector not only holds immense strategic importance for energy conservation, emission reduction, and environmental protection but also promises to become a vital new driver of economic growth for Hangzhou Gear, helping the company secure a competitive edge in tomorrow's market landscape.
