Description

Technical Field

[0001] This utility model relates to the field of generator set maintenance technology, specifically a flushing and circulation plug for the lubricating oil pipeline of the turbine body bearing of a generator set. Background Technology

[0002] During the later stages of unit maintenance, the lubrication system is generally required to be put into operation ahead of schedule and the oil must be flushed to meet the required standards before entering the bearings. However, due to bearing maintenance or other reasons, flushing is not possible, and the lubricating oil cannot be carried into all bearings for flushing and circulation. It is necessary to remove the filter screen in the bearing lubrication oil pipeline and install a flange plug. During the disassembly process, this plug is prone to loose sealing, making disassembly and installation difficult. It requires the cooperation of multiple people, which is time-consuming and labor-intensive, affecting the maintenance progress. Utility Model Content

It is applied to the lubricating oil pipeline of the turbine bearing to be sealed in the generator set. The lubricating oil pipeline has an internal annular platform. The plugging plate includes a sleeve, a first disc, a second disc, and a third disc. The first disc and the second disc are respectively fixed to the top and bottom of the sleeve. A screw is fixed to the top of the first disc. A through hole is provided in the center of the third disc. The third disc passes through the through hole, passes through the screw, and is fixed to the top of the first disc by a fixing nut. A sealing gasket is also provided between the first disc and the third disc. The plugging plate is inserted into the lubricating oil pipeline and fixed by a flange located at the outer port of the pipeline. The first disc is held in place on the annular platform, and the sealing gasket is in contact with the annular platform.

[0005] Optionally, the first disc is fixed to the top of the sleeve by welding, and the second disc is fixed to the bottom of the sleeve by welding.

[0006] Optionally, the screw is fixed to the top of the first disk by welding.

[0007] Optionally, the sealing gasket includes a circular rubber gasket.

Figure 3 This is a schematic diagram illustrating the application of a flushing and circulation plug plate in the lubricating oil pipeline of a generator set turbine body bearing, according to an embodiment of this utility model. Figure 4 This is a three-dimensional schematic diagram of a portion of the structure of a flushing and circulation blockage plate for the lubricating oil pipeline of a turbine body bearing in a generator set, according to an embodiment of this utility model. Figure 3 As shown in the embodiment of this utility model, the blocking plate is applied to the lubricating oil pipeline 8 of the bearing bush to be blocked in the turbine body of the generator set, and the lubricating oil pipeline 8 of the bearing bush to be blocked is provided with a circular platform 9 inside.

[0016] Specifically, such as Figure 1-4 As shown, the blocking plate includes: sleeve 4, first disc 1, second disc 2 and third disc 3, with the first disc 1 and the second disc 2 respectively fixedly disposed at the top and bottom of sleeve 4.

[0017] A screw 5 is fixedly installed on the top of the first disc 1, and a through hole is provided in the center of the third disc 3.
