屏蔽泵型号参数及屏蔽泵结构图
屏蔽泵型号,屏蔽泵结构,屏蔽泵结构图
屏蔽泵结构通常按泵冷却润滑循环回路的形式定义。屏蔽泵型号按照不同的结构也分为多种。
一、屏蔽泵结构及屏蔽泵结构图
1、正循环屏蔽泵结构
屏蔽泵正循环结构也称基本型结构或称普通型结构，如图15-2所示，从泵体出口法兰处设置引液管引入冷却液，这种卧式屏蔽泵结构用于输送一般性非易汽化介质。
当输送易汽化介质时，冷却液经后导轴承、屏蔽套、前导轴承回到叶轮进口，冷却液的温度由低变高，部分冷却液可能已汽化产生气泡，带气泡的介质进入叶轮进口将堵塞叶轮进口流道，导致泵性能下降，严重时泵将出现断流，冷却液也就不能循环工作。所以，这种结构适用于一般的非易汽化介质的输送。

2．逆循环屏蔽泵结构
逆循环结构也称之为易汽化型结构，如图15—3所示，从泵腔处引入高压流体，一部分冷却屏蔽套、后导轴承后，经循环管独立回到泵的人口罐的气相部；另一部分冷却液只冷却前导轴承，回到叶轮进口，这一部分冷却液温升极小，不至于出现汽化。因此，这种结构适用于输送易汽化介质。

3．独立循环屏蔽泵结构
独立循环结构屏蔽泵如图15—4所示，独立循环结构也称之为高温型结构。
在泵转辅上设置一辅助叶轮4，由辅助叶轮实现独立循环工作。循环液由辅助叶轮出口经过盘管流入底部润滑下导轴承、屏蔽套以及上导轴承，构成循环回路。循环液盘管外部由一冷却水套包覆，冷却水套设有进出管冷却。输送介质与循环回路介质几乎不交换，使电动机避免高温工作。因此，这种结构适用于输送高温介质。

4．多级叶轮屏蔽泵结构
多级叶轮屏蔽泵结构如图15—5所示。图15—为卧式多级结构，15—5b为立式多级结构，15-5c为两端叶轮全对称结构。
多级叶轮屏蔽泵的叶轮通常均分左右两部分，叶轮背靠背，实现轴向力平衡。与低比转速同参数的单级叶轮相比，多级屏蔽泵比转速大大增加，从而提高了泵的效率。许多高扬程参数采用单级叶轮是无法实现的。
双级叶轮全对称屏蔽泵，屏蔽电动机左右轴端各设置一个叶轮，转子几乎没有轴向力，泵运行平稳、可靠。

5．微型屏蔽泵结构
图15—6所示是一种微型屏蔽泵。微型屏蔽电动机有单相、三相两种。微型屏蔽泵定子屏蔽套役有和定子焊死，是通过平垫压紧的可拆结构。转轴是空心轴，循环液流经屏蔽套从轴中心孔回到叶轮人口。该泵适用于家庭供水、增压等。国内生产的微型屏蔽泵大量出口到国外。
