[0002] The main lubricating oil system is a crucial component of large vessels. Prior art main lubricating oil systems include the main lubricating oil line, crosshead lubricating oil line, and supercharger return oil line. The entire system is extremely large. After the main lubricating oil system is installed, the lubricating oil line must be cleaned. Substandard cleaning can cause wear or damage to components such as the main engine's cylinders and main bearings. Because the lubricating oil in the system is often high in impurities, and crosshead pumps are typically highly accurate, impurities in the lubricating oil can cause wear or damage to the crosshead pump. Therefore, the crosshead pump cannot be used during this initial lubricating process. This results in insufficient pressure in the crosshead lubricating oil line, resulting in long periods of unclean lubricating, which increases the lubricating cycle. Furthermore, some pipelines, such as the cylinder oil line and the main engine free end line, are disassembled for complete installation, due to factors such as on-site alignment, bracket positioning, and spur positioning, which make it difficult to control flow rate and flow rate. This double disassembly and assembly increases the overall construction period, and during reassembly, there is a risk of foreign particles entering the piping system. Therefore, how to achieve high-quality construction requirements, reduce labor intensity, and control and shorten the cycle is an urgent problem that technical personnel in this field need to solve.

[0054] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0055] It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner. Although the illustrations only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation, the form, quantity, positional relationship and proportion of each component in actual implementation can be changed at will under the premise of realizing the technical solution of this party, and the component layout form may also be more complicated.

[0056] Example 1

[0057] This embodiment provides an oiling tool for the main lubricating oil system of a ship, such as Figure 1 As shown, it includes a distributor 10, a transfer tube 20 and a measuring probe.

[0058] Reference Figure 1 and Figure 2 As shown, the distributor 10 is provided with a connecting flange 11, which is connected to the first outflow end 101 of the main lubricating oil pipeline 100 via a second jumper pipe 32. During the oil cleaning process, the lubricating oil flows out of the first outflow end 101 of the main lubricating oil pipeline 100 and flows into the distributor 10 through the connecting flange 11. In this embodiment, the outer diameter of the connecting flange 11 is 200 mm.

[0059] Reference Figure 1 and Figure 2 As shown, the distributor 10 is also provided with multiple connectors, each of which is connected to a plurality of pipelines, through which lubricating oil flows into the plurality of pipelines. The multiple connectors include a first connector 41, a second connector 42, a third connector 43, a fourth connector 44, and a fifth connector 45. The first connector 41 is connected to the free-end discharge pipeline 200, the second connector 42 is connected to the supercharger return oil pipeline 300, the third connector 43 is connected to the crosshead lubricating oil pipeline 400, the fourth connector 44 is connected to the cylinder oil inlet pipeline 500, and the fifth connector 45 is connected to the drive-end return oil pipeline 600. As an example, the inner diameters of the two ends of the connector are unequal, and the inner diameter of the end connected to the shutoff valve is smaller than the inner diameter of the other end.

[0060] As an example, a stop valve is provided between each joint and the pipeline to control the flow direction of the lubricating oil. Figure 2 As shown, a first stop valve 51 is installed on the first connector 41, a second stop valve 52 is installed on the second connector 42, a third stop valve 53 is installed on the third connector 43, a fourth stop valve 54 is installed on the fourth connector 44, and a fifth stop valve 55 is installed on the fifth connector 45. In this embodiment, the inner diameter of the first stop valve 51 is 150 mm, the inner diameter of the second stop valve 52 is 80 mm, the inner diameter of the third stop valve 53 is 100 mm, the inner diameter of the fourth stop valve 54 is 80 mm, and the inner diameter of the fifth stop valve 55 is 50 mm; the stop valves and connectors are connected by connecting bolts (not shown in the figure), and each stop valve is connected to each pipeline through a second jumper tube 32.

[0061] like Figure 2 As shown, a thermometer 80 is also installed on the distributor 10 for measuring the temperature of the lubricating oil in the distributor 10 .

[0062] As an example, the transfer tube 20 has a first opening 21 and a second opening 22, and the plane where the first opening 21 and the second opening 22 are located is perpendicular. In this embodiment, the transfer tube 20 is an arc-shaped structure. In an optional embodiment, as Figure 1 As shown, the first opening 21 is connected to the crosshead lubricating oil pipeline 400, and the second opening 22 is connected to the crosshead lubricating oil temporary return pipe 403, and at this time, the second outflow end 102 of the main lubricating oil pipeline 100 is provided with a blocking plate 60. In another optional embodiment, as Figure 3 As shown, the first opening 21 is connected to the crosshead lubricating oil pipeline 400 , and the second opening 22 is connected to the second outflow end 102 of the main lubricating oil pipeline 100 .

[0063] like Figures 4a-4b As shown, the measuring probe is installed on the outer wall of multiple pipelines to measure the flow rate of the lubricating oil in the pipeline. The measuring probe includes a first probe 71 and a second probe 72, which are arranged in the direction of the pipeline axis ( Figure 4a and 4b In the X-axis direction shown in FIG, the distance between the first probe 71 and the second probe 72 is between 90 mm and 110 mm, preferably 100 mm. In an optional embodiment, as shown in FIG. Figure 4a As shown, if the inner diameter of the pipeline is less than or equal to 50 mm, the first probe 71 and the second probe 72 are installed on the same side of the pipeline, and the installation directions of the first probe 71 and the second probe 72 are the same. In another optional embodiment, as Figure 4b As shown, if the inner diameter of the pipeline is greater than 50 mm, the first probe 71 and the second probe 72 are installed on opposite sides of the pipeline, and the installation directions of the first probe 71 and the second probe 72 are opposite.

[0064] As an example, the first probe 71 and the second probe 72 are connected to a portable ultrasonic measuring device (not shown in the figure). The portable ultrasonic measuring device has a display screen that can display the flow rate of the lubricating oil in the pipeline measured by the measuring probe, so as to facilitate the judgment of whether the lubricating oil flow rate meets the oil injection requirements.

[0065] like Figure 1 As shown, the crosshead lubricating oil pipeline 400 includes a first pipeline 401, a second pipeline 402, and a first jumper tube 31. One end of the first pipeline 401 is connected to the third connector 43, and the other end is connected to the second pipeline 402 through the first jumper tube 31. In this embodiment, the end of the first pipeline 401 connecting to the second pipeline 402 has two openings, so two first jumper tubes 31 are provided. Correspondingly, the end of the second pipeline 402 connecting to the first pipeline 401 also has two openings, and the other end of the second pipeline is connected to the first opening 21 of the transfer tube 20. As an example, the first jumper tube 31 is used to replace the crosshead pump (not shown). Since the lubricating oil in the system will contain many impurities during the initial oil injection, and the crosshead pump is generally more precise, replacing the crosshead pump with the first jumper tube 31 during the initial oil injection can prevent impurities in the lubricating oil from causing wear or damage to the crosshead pump.

[0066] In the first stage of oil cleaning, that is, the initial stage of oiling, if Figure 1 As shown, the second opening 22 of the transfer pipe 20 is connected to the crosshead lubricating oil temporary return pipe 403. In this case, the lubricating oil flowing out of the third joint 43 enters the first pipe 401 of the crosshead lubricating oil pipeline 400, flows into the second pipe 402 through the first jumper pipe 31, and flows to the crosshead lubricating oil temporary return pipe 403 through the transfer pipe 20. The lubricating oil is then purified and circulated. In the second stage of oil cleaning, when there are fewer impurities in the lubricating oil, the first jumper pipe 31 is removed, and the first pipe 401 and the second pipe 402 are connected via a crosshead pump. Figure 3As shown, the second opening 22 of the transfer tube 20 is connected to the second outflow end 102 of the main lubricating oil pipeline 100. In this case, the lubricating oil in the main lubricating oil pipeline 100 flows out through the first outflow end 101 and the second outflow end 102 respectively, wherein the lubricating oil flowing out through the second outflow end 102 flows into the crosshead lubricating oil pipeline 400 through the transfer tube 20.

[0067] Example 2

[0068] This embodiment provides a method for using an oiling tool for a main lubricating oil system of a ship, comprising the following steps:

[0069] S1: Provide an oiling tool for the main lubricating oil system of the ship;

[0070] As an example, the oiling tool is the oiling tool for the main lubricating oil system of a ship described in Example 1. Its specific structure can be found in the description of Example 1 and will not be repeated here.

[0071] S2: Connect the second opening of the transfer pipe to the temporary oil return pipe of the crosshead lubricating oil, and install a blocking plate at the second outflow end of the main lubricating oil pipeline;

[0072] Reference Figure 1 As shown, the second opening 22 of the transfer tube 20 is connected to the temporary crosshead oil return pipe 403, and a blocking plate 60 is installed at the second outflow end 102 of the main oil pipeline. Furthermore, a first jumper tube 31 is used to connect the first pipeline 401 and the second pipeline 402 of the crosshead oil pipeline 400. Using the first jumper tube 31 instead of the crosshead pump can prevent impurities in the oil from causing wear or damage to the crosshead pump.

[0073] S3: performing a pump pressure test on the oil feeding tool to check the air tightness of the oil feeding tool;

[0074] As an example, the oil filling tool is Figure 1 After the connection is completed, the tooling is subjected to a pump pressure test. Specifically, by controlling the on / off control of each stop valve, each pipeline is checked for air tightness, and any leaks are promptly pried tight. In this embodiment, the gas pressure used in the pump pressure test is 0.6 MPa.

[0075] S4: Lubricating oil is added to the main lubricating oil pipeline, and the lubricating oil flows to each pipeline in batches through the distributor to clean each pipeline.

[0076] First, after the air tightness check is correct, lubricating oil is added and the main lubricating oil pump is started to feed oil into the oil delivery pipeline. The lubricating oil flows into the distributor 10 through the first outflow end 101 of the main lubricating oil pipe 100, the second jumper pipe 32 and the connecting flange 11, and the pipeline is checked again for leakage.

[0077] Next, open the second stop valve 52, the fourth stop valve 54 and the fifth stop valve 55 to allow the lubricating oil to flow into the supercharger return oil pipeline 300, the cylinder oil inlet pipeline 500 and the drive end return oil pipeline 600, and clean the above pipelines with oil until the above pipelines meet the cleaning requirements. If any pipeline does not meet the cleaning requirements, the opening of the stop valve can be controlled to make the lubricating oil flow rate in the pipeline meet the specified requirements.

[0078] Next, close the second stop valve 52, the fourth stop valve 54 and the fifth stop valve 55, and open the first stop valve 51 and the third stop valve 53 to allow the lubricating oil to flow into the free end discharge pipeline 200 and the crosshead lubricating oil pipeline 400, and clean the above pipelines with oil until the above pipelines meet the cleaning requirements. If any pipeline does not meet the cleaning requirements, the opening of the stop valve can be controlled to make the lubricating oil flow rate in the pipeline meet the specified requirements.

[0079] As an example, the free end discharge pipeline 200, the supercharger return oil pipeline 300, the crosshead lubricating oil pipeline 400, the cylinder oil inlet pipeline 500 and the drive end return oil pipeline 600 are alternately oiled and cleaned until all pipelines meet the oil cleaning requirements.

[0080] As an example, during the cleaning process, a measuring probe installed in the pipeline and a portable ultrasonic measuring device are used to measure the flow rate and flow velocity within the pipeline to determine whether the cleaning requirements are met. In this embodiment, the cleaning requirement is a Reynolds number ≥ 3000. In addition, the lubricating oil temperature is monitored using a thermometer 80 and maintained between 45°C and 55°C.

[0081] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
