Abstract
Description
Technical Field
[0001] This invention relates to the field of marine engine cleaning technology, and in particular to an integrated marine oil injection device and its usage method. Background Technology
[0002] Main lubricating oil is a very important oil used on board. The cleanliness level of the oil directly affects the operating condition of the equipment. To ensure the cleanliness of the main lubricating oil, the main lubricating oil daily piping system (external piping) and the lubricating oil piping system of the main engine body (internal piping) need to be flushed with oil to remove impurities such as welding slag and spatter from the pipelines, thus ensuring the cleanliness of the main lubricating oil.
[0003] Traditional rinsing methods such as Figure 1 As shown, temporary connecting pipes are typically used to connect the external piping into a closed loop, and an external flushing device is used for circulating flushing. After the external piping passes the flushing test, the temporary pipes need to be removed, the flushing loop reconfigured, and the internal piping of the main unit flushed again. Although this method is widely used, it has several obvious drawbacks. First, during the switching phase between external and internal piping flushing, multiple disassemblies and reconnections of the piping are required, which not only results in a long operation cycle but also leads to a significant amount of waiting time, extending the overall flushing project duration. Second, frequent disassembly and reinstallation of piping can easily introduce external contaminants, especially during the flipping and reconnection process, where previously cleaned pipe sections may be recontaminated, significantly increasing the risk of impurities entering the system. In addition, traditional methods lack real-time and reliable cleanliness monitoring means, making it impossible to monitor whether the oil cleanliness meets the standards in real time.
[0004] Therefore, optimizing the flushing process, reducing system switching time, avoiding secondary pollution, and achieving online monitoring and real-time assessment of cleanliness have become key issues that technical personnel in the field of marine engineering urgently need to address.
