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

[0018] 1. The gear pump is mounted on a 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. When the input shaft rotates, the input shaft drives the pump shaft to rotate, causing the gear pump to start. This eliminates the need for a separate drive device to drive the gear pump, thereby reducing product production costs. One end of a first oil return pipe is connected to the oil outlet, and the other end of the first oil return pipe is connected to the input end of the gear pump, so that the gear pump can draw lubricating oil from the housing through the first oil return pipe and the oil outlet. Simultaneously, the input end of the filter is connected to the output end of the gear pump, the input end of the cooler is connected to the output end of the filter, and both ends of the second oil return pipe are connected to the output end of the cooler and the oil return hole, respectively, so that the lubricating oil drawn in by the gear pump flows into the filter and cooler in sequence, thereby filtering and cooling the lubricating oil. The lubricating oil is then injected into the housing to lubricate and cool the first external teeth and gears within the housing, thereby improving product quality.

[0019] 2. By sleeves of two first bearings on both ends of the input shaft, sleeves of the second bearing on the outside of the input shaft, the two first bearings are embedded in the housing, and the second bearing is embedded in the first bearing seat, so that the housing and the first bearing seat respectively support the input shaft through the two first bearings and the second bearing, thereby improving the rotational stability of the input shaft; by setting the first bearing as a spherical roller bearing and the second bearing as a four-point contact ball bearing, the two spherical roller bearings cooperate to eliminate the axial force of the input shaft, thereby improving the rotational stability of the input shaft. At the same time, the radial load and axial load of the input shaft are borne by the four-point contact ball bearing, further improving the rotational stability of the input shaft.

[0020] 3. By passing multiple connecting bolts through the connecting part and embedding multiple connecting bolts into the input shaft, the connecting part and the input shaft are connected together through the connecting bolts, thereby achieving synchronous rotation of the input shaft and the pump shaft. Compared with connecting the pump shaft and the input shaft together through a spline shaft, the synchronization of the rotation of the pump shaft and the input shaft can be improved, thereby avoiding lag in the rotation of the pump shaft, thereby improving the user experience of the product.

[0021] 4. By installing two third bearings on both ends of the output shaft, installing the fourth bearing on the outside of the output shaft, embedding the two third bearings in the housing, and embedding the fourth bearing in the second bearing seat, the housing and the second bearing seat respectively support the output shaft through the two third bearings and the fourth bearing, thereby improving the rotational stability of the output shaft; by setting the third bearing as a spherical roller bearing and the fourth bearing as a four-point contact ball bearing, the two spherical roller bearings cooperate to eliminate the axial force of the output shaft, thereby improving the rotational stability of the output shaft. At the same time, the four-point contact ball bearing bears the radial load and axial load of the output shaft, further improving the rotational stability of the output shaft.

[0022] 5. By connecting the first oil filling pipe and the first oil guide groove, and arranging the first oil guide groove opposite to the first bearing, lubricating oil can be injected into the first bearing through the first oil filling pipe and the first oil guide groove, thereby lubricating and cooling the first bearing. Compared with lubricating the first bearing with glycerin, lubricating with lubricating oil can prevent dust and impurities from entering the first bearing, thereby preventing damage to the first bearing. At the same time, it can also prevent damage to the first bearing due to volatilization of glycerin, thereby extending the service life of the first bearing.

[0023] 6. By connecting the second oil injection pipe and the second oil guide groove, and arranging the second oil guide groove opposite to the third bearing, 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 damage to the third bearing. At the same time, it can also prevent damage to the third bearing due to glycerin volatilization, thereby extending the service life of the third bearing.

[0024] 7. By disposing a first annular groove 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 oil guide groove, the lubricating oil in the first oil guide groove flows into the first annular groove, thereby achieving lubrication and cooling of the first bearing from all angles, thereby avoiding the situation where the rest of the first bearing is damaged by overheating due to single-point lubrication and cooling of the first bearing, thereby improving product quality. By disposing a second annular groove in the housing, the second annular groove is arranged around the outside of the third bearing, and the second annular groove is connected to the second oil guide groove, thereby achieving lubrication and cooling of the third bearing from all angles, thereby avoiding the situation where the rest of the third bearing is damaged by overheating due to single-point lubrication and cooling of the third bearing, thereby improving product quality.

[0025] 8. By setting multiple 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 multiple 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, avoiding damage to the first external tooth and the second external tooth, and improving product quality.

[0026] 9. By positioning the first connecting groove on the outer wall of one end of the input shaft and locating it outside the housing, the drive device can be connected to the input shaft via the first connecting groove, thereby simplifying the connection between the drive device and the input shaft and improving the product user experience. By positioning the second connecting groove on the outer wall of one end of the output shaft and locating it outside the housing, the load device can be connected to the output shaft via the second connecting groove, thereby simplifying the connection between the load device and the output shaft and improving the product user experience.

[0027] 10. By placing an observation port on the top of the box, fastening an observation cover to the port, connecting the observation cover to the box, and making the observation cover transparent, the operating conditions inside the box can be observed through the observation cover, allowing for timely replacement of parts inside the box, thereby improving the user experience of the product. By installing a vent hood on the observation cover and connecting the vent hood to the interior of the box, the vent hood can balance the air pressure inside and outside the box, thereby improving the user experience of the product.
