Abstract
Description
Technical Field
[0001] This application relates to the field of nuclear power plant equipment, and more particularly to an oil change system for a drum screen spindle bearing. Background Technology
[0002] Currently, the oil change method for the main shaft bearings of nuclear power plants in China still relies on the most traditional manual method. The main oil change process is as follows: When draining oil, the lower drain plug is opened, allowing the lubricating oil to flow out by gravity. Before draining, an oil receiving container needs to be placed at the drain port. Due to the structural limitations of the main shaft, the waste oil needs to be emptied multiple times. Once it is confirmed that no more lubricating oil is flowing out, the drain plug is tightened back on. When adding oil, the oil tank filler neck is opened, a funnel is placed, and lubricating oil is poured into the funnel until it is full. The entire oil change process relies entirely on manual labor, lacking any automation. Furthermore, due to the high viscosity of the lubricating oil, multiple emptyings are required, resulting in problems such as long oil change times, incomplete draining, and leakage leading to environmental pollution.

[0023] The following is in conjunction with the appendix Figure 1 The provided embodiments further illustrate the oil change system for the spindle bearing of the mesh screen proposed in this application.
[0024] Reference Figure 1This application provides an oil changing system for a drum mesh spindle bearing 100, comprising a first container 300 and a second container 400. The first container 300 holds the new oil to be replaced, and the second container 400 holds the old oil removed from the drum mesh spindle bearing 100. A first connecting pipe 110 and a second connecting pipe 120 are provided on the drum mesh spindle bearing 100. The first connecting pipe 110 is positioned above the drum mesh spindle bearing 100, with one end connected to the interior of the drum mesh spindle bearing 100 and the other end connected to a first quick connector 111. The second connecting pipe 120 is positioned on the drum mesh spindle bearing 100, with one end connected to the bottom of the drum mesh spindle bearing 100 and the other end connected to a second quick connector 121. The drum mesh spindle bearing oil changing system includes an oil filling pipe and an oil drain pipe. One end of the filling pipe is detachably connected to the first quick connector 111, and the other end is connected to the bottom of the first container 300. A delivery pump 231 is installed on the filling pipe. One end of the drain pipe is detachably connected to the second quick connector 121, and the other end is connected to the top of the second container 400. A delivery pump 231 is also installed on the drain pipe. The drum spindle bearing oil changing system also includes a control device 500, which is connected to and controls the operation of the delivery pump 231. Using the drum spindle bearing oil changing system of this application, the oil changing operation is realized through the control device 500, which can accurately control the filling amount and realize intelligent operation of the oil changing process. It can reduce the dependence on manpower in the oil changing process, avoid the problems of long manual oil changing time and incomplete oil draining, make the entire oil changing process more convenient and faster, and reduce oil leakage and reduce the risk of environmental pollution.
[0025] Furthermore, in some embodiments, such as Figure 1As shown, the refueling pipe includes a first pipe section 210 and a second pipe section 220. The first pipe section 210 is connected to a first quick connector 111, and the second pipe section 220 is connected to a first container 300. The drain pipe includes a third pipe section 240 and a fourth pipe section 250. The third pipe section 240 is connected to a second quick connector 121, and the fourth pipe section 250 is connected to a second container 400. A delivery pipe section 230 is provided between the first pipe section 210 and the second pipe section 220, and between the third pipe section 240 and the fourth pipe section 250. One end of the delivery pipe section 230 is connected to the first pipe section 210 and the third pipe section 240 respectively via a first three-way valve 260, and the other end of the delivery pipe section 230 is connected to the second pipe section 220 and the fourth pipe section 250 respectively via a second three-way valve 270. A control device 500 is connected to the first three-way valve 260 and the second three-way valve 270 respectively, and the control device 500 controls the switching between the first three-way valve 260 and the second three-way valve 270. When the drum mesh main shaft bearing 100 is lubricated, the delivery pipe section 230 is connected to the first pipe section 210 via the first three-way valve 260, and the delivery pipe section 230 is connected to the second pipe section 220 via the second three-way valve 270. The first pipe section 210, the delivery pipe section 230, and the second pipe section 220 are sequentially connected to form the lubrication pipe. When the drum mesh main shaft bearing 100 is drained, the delivery pipe section 230 is connected to the third pipe section 240 via the first three-way valve 260, and the delivery pipe section 230 is connected to the fourth pipe section 250 via the second three-way valve 270. The third pipe section 240, the delivery pipe section 230, and the fourth pipe section 250 are sequentially connected to form the drain pipe. Through the above connection, the lubrication pipe and the drain pipe share a section of the delivery pipe section 230, thereby reducing the number of delivery pumps 231 installed on the delivery pipe section 230, achieving the effect of reducing accessories and facilitating control. It is understood that in other embodiments, the lubrication pipe and the drain pipe can also be two completely independent pipelines.
[0026] In some embodiments, such as Figure 1 As shown, the delivery pump 231 is installed on the delivery pipe section 230. The delivery pump 231 is a bidirectional pump, so only one delivery pump 231 is needed to complete the steps of refueling and discharging oil.
[0027] In some embodiments, such as Figure 1 As shown, the first pipe section 210, the second pipe section 220, the third pipe section 240 and the fourth pipe section 250 are all flexible pipes, which can be easily bent without worrying about leakage, and at the same time better adapt to the positions of the first container, the second container and the delivery pipe section 230.
[0028] In some embodiments, the first pipe section 210 is provided with a connector structure that matches the first quick connector 111, and the third pipe section 240 is provided with a connector structure that matches the second quick connector 121. The matching connector structures can accelerate the assembly and disassembly of the first pipe section 210 and the first quick connector 111, as well as the assembly and disassembly of the third pipe section 240 and the second quick connector 121, thereby improving efficiency.
[0029] In some embodiments, sealing structures are provided between the joint structures of the first quick connector 111 and the first pipe section 210, and between the joint structures of the second quick connector 121 and the third pipe section 240, respectively. Through the sealing structures, the sealing performance of the first quick connector 111 and the first pipe section 210, and the second quick connector 121 and the third pipe section 240 can be enhanced to prevent oil leakage.
[0030] In some embodiments, the control device 500 includes a display screen that can display the status process of oil being added to or drained from the drum web spindle bearing 100.
[0031] In some embodiments, the display screen is a touch screen, which allows users to directly input commands on the display screen for control.
[0032] In some embodiments, such as Figure 1 As shown, the control device 500 includes a power module 510, which is connected to the control device 500. Using an independent power module 510 to power the control device 500 makes its operation more stable.
[0033] In some embodiments, valve switches are respectively provided on the first pair of connectors 110 and the second pair of connectors 120. When the first pair of connectors 110 and the second pair of connectors 120 are not in use, the corresponding valve switches can be closed to prevent the oil inside the drum screen spindle bearing 100 from leaking through the first pair of connectors 110 and the second pair of connectors 120.
[0034] The application process of the drum mesh spindle bearing oil change system of this application is as follows: Before changing the oil in the drum mesh spindle bearing 100, first connect the first pipe section 210 to the first quick connector 111 and the third pipe section 240 to the second quick connector 121, and check and ensure the reliability of the connection; when changing the oil, firstly, the control device 500 controls the first three-way valve 260 and the second three-way valve 270 to switch, so that the third pipe section 240, the delivery pipe section 230 and the fourth pipe section 250 are connected in sequence to form an oil drain pipe, and at the same time, the delivery pump 231 is in the oil draining mode, so that the drum mesh spindle bearing 100 is internally lubricated. The lubricating oil is extracted and flows to the second container 400 for recycling. Then, after the lubricating oil inside the drum mesh spindle bearing 100 is completely drained, the control device 500 controls the first three-way valve 260 and the second three-way valve 270 to switch again, so that the first pipe section 210, the delivery pipe section 230 and the second pipe section 220 are connected in sequence to form a filling pipe. At the same time, the delivery pump 231 is in filling mode, and the delivery pump 231 extracts new lubricating oil from the first container 300 and delivers it to the drum mesh spindle bearing 100 through the filling pipe. When the drum mesh spindle bearing 100 is filled with sufficient lubricating oil, the oil change process is completed. The drum mesh spindle bearing oil change system of this application realizes the oil change operation by inputting commands into the control panel through the human-machine interface, selecting the mode, and performing the oil draining and filling operations. During on-site execution, once the device is set up, commands are input through the human-machine interface on the control panel, and the system can then perform the oil draining or refueling process according to the commands. This achieves intelligent operation, reduces reliance on manpower, and avoids problems such as long manual oil change times, incomplete oil draining, and oil leakage that pollute the environment, making the entire oil change process more convenient, faster, more environmentally friendly, and more intelligent.
[0035] It is understood that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application. It should be noted that, for those skilled in the art, without departing from the concept of this application, the above technical features can be freely combined, and several modifications and improvements can be made, all of which fall within the protection scope of this application. Therefore, all equivalent transformations and modifications made within the scope of the claims of this application should fall within the coverage of the claims of this application.
