Since the beginning of this year, Dalian Marine Diesel Engine Co., Ltd. has reported a lot of intellectual property work. The processing technology of large-scale low-speed marine diesel engine cylinder liner wear ring, diesel engine lubrication system warming machine and test bench test technology have successively obtained the invention patent authorization from the State Intellectual Property Office. Up to now, the company has owned 3 national invention patents and 10 utility model patents, marking a new progress in intellectual property work.
It is understood that the acquisition of a national invention patent is not counted as research and development time. It takes three years from the time of filing to approval. The so-called "invention patent" is to protect the new technical solutions proposed by the structure, manufacturing method, manufacturing process or improvement of the product. This technical solution should be highly creative. Taking the diesel engine lubrication system warming machine and the test bench test technology as an example, according to the inventor of this patent, since the hydraulic unit of the electronically controlled main engine has special requirements for the cleanliness of the lubricating oil, the electronic control manufactured by a domestic machine manufacturer The main engine was used for one and a half months, and the cleanliness of the lubricating oil system did not meet the design requirements. In order to solve this problem, our relevant personnel have designed a separate hydraulic unit oil system through a large number of investigations and demonstrations. The supply and return lines in the lubrication system of the diesel engine and the supply and return lines of the hydraulic control unit are separated. Two independent, closed diesel engine lubrication systems. In this way, the residue and the debris in the diesel oil system of the diesel engine are prevented from entering the hydraulic control unit. The successful application of the process reduces the oil-stringing work of the electronic control host to about five days, greatly improving work efficiency and saving valuable resources and time. MAN experts also turned this process into a lack of understanding from the beginning.
At present, due to the influence of the market environment, shipowners are increasingly strict with the performance and quality requirements of the host. Therefore, it is necessary to further enhance the awareness of patent certification, apply for patents in time for new technologies and new technologies developed during product development, and try to Strive to obtain certification from a number of classification societies and authorities to further expand the market sales.
Having a patent is also a manifestation of the company's strength, which means that the product is more easily recognized and accepted by customers, thereby improving the market competitiveness of the product. Since its establishment, the company has always adhered to the road of localization technology innovation of “introduction – digestion – absorption – innovationâ€. In 2011, the company issued the “DMD Intellectual Property Strategyâ€, which strengthened the technical cooperation with relevant research institutes in China, focused on precision welding and automatic welding technology for large structural parts, and committed to some key parts processing technologies. Research to overcome technical bottlenecks in the production process. The company has also set up some special research groups on manufacturing technology, and formulated relevant and relevant incentive policies to create a good technological innovation environment for employees.
