Description

一种用于核电厂海水循环泵齿轮箱盘车润滑的工装
技术领域
本实用新型属于机械检修领域,具体涉及一种用于核电厂海水循环泵齿轮箱盘车润滑的工装。
背景技术
福清核电1-4号机组共有8台海水循环泵,每台泵由一台立式电动机通过一台FQHDL35型或HDBT411型立式行星齿轮箱驱动水利部件运转。
按照设备定期维护要求,核电厂大修期间需通过盘动海水循环泵电机轴以检查电机、齿轮箱、泵轴的轴系对中情况和设备部件的质量情况。齿轮箱下部组合轴承(含推力轴承和导向轴承)瓦面、上部行星芯包装置的行星轮轴瓦面均为巴氏合金结构,因此盘车转动过程均需进行润滑油润滑,否则组合轴承瓦面、行星轮轴瓦面将因润滑不足造成磨损烧毁等设备质量问题,严重影响大修进度及核电厂经济效益。
核电厂大修期间,齿轮箱润原设计滑油系统处于停运状态,无法为齿轮箱行星芯包装置及组合轴承提供润滑油,因此需发明一套齿轮箱盘车润滑工装以满足检修需求。
发明内容
本实用新型的目的在于:提供一种用于核电厂海水循环泵FQHDL35型或HDBT411型立式行星齿轮箱盘车润滑的工装。
本实用新型的技术方案如下:一种用于核电厂海水循环泵齿轮箱盘车润滑的工装,包括一台低压润滑油泵和一台高压润滑油泵;
所述的低压润滑油泵,包括驱动电机A、联轴器A和齿轮泵,其中驱动电机A通过联轴器A与齿轮泵相连,所述齿轮泵的进口管路和出口管路的末端分别通过一个低压球阀与进油口管接头A和出油口管接头A相连;所述的低压润滑油泵的各部件安装在便携小车A上;
所述的高压润滑油泵,包括驱动电机B、联轴器B和柱塞泵,其中驱动电机B通过联轴器B与柱塞泵相连,所述柱塞泵出口管路的末端依次通过一个高压球阀和一个压力表与出油口管接头B相连,柱塞泵进口管路的末端通过另一个高压球阀与进油口管接头B相连;所述的高压润滑油泵的各部件安装在便携小车B上。
所述的低压润滑油泵,通过油管连接到齿轮箱的润滑油系统的供油口,以满足行星芯包装置润滑的需求。
所述的高压润滑油泵,通过油管连接到齿轮箱的组合轴承的润滑油系统的高压油管供油口,以满足推力轴承建立油膜的需求。
所述的便携小车A的下方设有脚轮A。
所述的便携小车B的下方设有脚轮B。
本实用新型的显著效果在于:现有技术为人工淋油润滑,其效率极低、润滑效果不充分且异物引入的风险极高,均易造成瓦面磨损烧毁;而本工装为电动驱动,可持续为齿轮箱组合轴承及行星芯包装置提供均匀、清洁的润滑油,较现有人工淋油润滑技术更为高效、安全、科学。
