[0017] Compared with the prior art, the desulfurization reducer of a power plant of the present invention has the following beneficial effects:

[0018] 1. The gear pump is installed on one side wall of the housing and the pump shaft of the gear pump is connected to the input shaft, so that the housing supports the gear pump, so that when the input shaft rotates, the input shaft will drive the pump shaft to rotate, so that the gear pump starts to start, and then there is no need to set up another driving device to drive the gear pump to work, so as to reduce the production cost of the product.

[0023] 6. By connecting the second oil injection pipe and the second oil guide groove, and making the second oil guide groove opposite to the third bearing, the lubricating oil can be injected into the third bearing through the second oil injection pipe and the second oil guide groove, thereby lubricating and cooling the third bearing. Compared with lubricating the third bearing with glycerin, lubricating with lubricating oil can prevent dust and impurities from entering the third bearing, thereby preventing the third bearing from being damaged. At the same time, it can also prevent the third bearing from being damaged due to the volatilization of glycerin, thereby extending the service life of the third bearing.

[0024] 7. By setting a first annular groove in the shape of an annular ring in the housing, the first annular groove is arranged around the outside of the first bearing, and the first annular groove is connected to the first guide groove, so that the lubricating oil in the first guide groove flows into the first annular groove, so that the lubricating oil lubricates and cools the first bearing from all angles, so as to avoid the situation where the rest of the first bearing is damaged due to overheating caused by single-point lubrication and cooling of the first bearing, thereby improving the quality of the product.

[0025] 8. By setting a plurality of oil drip holes at the bottom of the cooling pipe, connecting the cooling pipe with the third oil filling pipe, making the cooling pipe perpendicular to the third oil filling pipe, and making the cooling pipe above the meshing point of the first external tooth and the second external tooth of the gear, the lubricating oil in the third oil filling pipe can flow into the cooling pipe, and the lubricating oil can flow out through the plurality of oil drip holes to the meshing point of the first external tooth and the second external tooth, thereby lubricating and cooling the first external tooth and the second external tooth, so as to avoid damage to the first external tooth and the second external tooth, and improve the quality of the product.

[0026] 9.
