Embodiment Construction

[0017] see figure 1 and figure 2 , in order to better understand the technical solution of the present invention, the following specific embodiments are described in detail in conjunction with the accompanying drawings:

[0018] see figure 1 and figure 2 , On the boric acid recirculation pump, thin oil lubrication is used to lubricate between the pump shaft 4 and the bearing body 7. In order to prevent lubricating oil leakage, an oil seal system is set on the boric acid recirculation pump. The oil seal system is sleeved on the pump shaft 4 of the boric acid recirculation pump. An oil seal system for a boric acid recirculation pump in this embodiment includes: an oil retaining plate 1, a bearing cover 2 and a dustproof plate 3;

[0019] The bearing cover 2 includes a cover base 21, an annular cover 22 and a boss 23 located in the annular cover 22 are arranged on the top surface of the cover base 21, and the cover base 21, the annular cover 22 and the boss The platform 23...

Abstract

The invention discloses an oil seal system for a boric acid recirculation pump in the field of the nuclear power equipment. The oil seal system is sleeved on a pump shaft. The oil seal system comprises an oil baffle disc, a bearing cap and a dustproof disc. The bearing cap comprises a cap seat; an annular cover and a boss located in the annular cover are arranged on the top surface of the cap seat; the cap seat, the annular cover and the boss are concentric; an axial through hole axially penetrating the cap seat and the boss is arranged at the center of the bearing cap; the dustproof disc comprises a disc seat and a disc shaft; the disc seat and the disc shaft are concentric; the oil baffle disc and the dustproof disc are sequentially sleeved on the pump shaft; the bearing cap is sleeved on the outer wall of the disc shaft through the axial through hole; a flange is arranged on the top surface of the boss along the circumference of the boss; and a side shield is arranged on the bottom surface of the oil baffle disc along the circumference of the oil baffle disc. In this way, an oil way collection cavity is formed among the oil baffle disc, the dustproof disc and the bearing cap.

Description

technical field [0001] The invention relates to an oil seal system for a boric acid recirculation pump in the field of nuclear power equipment. Background technique [0002] The boric acid recirculation pump is a kind of recirculation pump often used in nuclear power plants. The function of the boric acid recirculation pump is: during the operation of the nuclear power plant, in order to prevent the crystallization of boric acid in the boric acid injection tank, the boric acid recirculation pump controls the boric acid in the boric acid injection tank. The boric acid solution is continuously circulated to ensure constant concentration and temperature of the boric acid solution. Another function of this pump is to complete the initial filling of the boric acid injection tank. [0003] The boric acid recirculation pump is provided with a pump shaft and a bearing body, and the pump shaft and the bearing body must be lubricated. Currently, the commonly used lubrication method i...
