屏蔽离心泵,卧式屏蔽泵,屏蔽泵
一、 卧式屏蔽离心泵简介
屏蔽离心泵是由水泵和屏蔽电动机构成一个密封整体,整体采用静密封设计。可以广泛使用在采暖、卫生用水、冷冻水系统中无腐蚀的冷水和热水的输送,它是宾馆、医院、工厂、高档住宅等热力交换站、管路集中供暖的理想输送设备。其较之于普通卧式离心泵有泵、机一体化结构紧凑,体积小、外形美观、运行平稳、安装方便、无噪音、零泄漏、等特点,大限度的满足用户日益增长的对工作环境的稳定性与环保要求。
二、卧式屏蔽离心泵结构
卧式屏蔽离心泵为卧式离心泵,电泵有水泵和屏蔽电动机(以下简称电机)两部分组成。水泵部分主要零部件叶轮、泵体、密封环,电机部分主要零部件有定子、转子、屏蔽套、轴承座、轴承、推力盘、冷却管、放气阀等零部件组成。
电机选用H级绝缘绕组。转子由不锈钢轴和铸铝转子组成。为了防止输送液体进入定子和腐蚀转子,在定子内径及转子表面分别用不锈钢屏蔽套密封。
密封性:泵体法兰与电机法兰连接处,机座与轴承座及定子屏蔽连接处均有耐热O型密封圈密封。
泵叶轮悬臂安装在电机转轴上,由键和螺母予以固紧。
润滑与冷却:采用外循环。当泵工作时,由电泵出口处引出少量液体经过冷却管、后轴承与轴颈间隙、定、转子间隙、前轴承与轴颈间隙、叶轮后口环组成一循环回路(单级)、后一级叶轮进口环组成一循环回路(多级)。
