这种泵有这样的特点你知道吗 ?

脱硫泵主要是应用在一些污染比拟凶猛的企业里面比方一些大型的火力发电厂,由于这些电厂大多都是采用比拟成熟的工艺停止烟气脱硫。这种办法比拟简单,所以最为普遍。那接下来我就为大家引见一下脱硫泵的构造特性。根或油浸石墨盘根;当泵的工作压力在0.5MPa以上时,可以运用聚四氟乙烯盘根或碳素纤维浸聚四氟乙烯盘根。

吸收塔循环泵是烟气脱硫装臵中的大型关键设备,安装对其牢靠性及运用寿命有很高请求。FGD安装耗费的电能有一半以上用于驱动吸收塔循环泵。因而,循环泵应具有较高的效率。泵的水力设计、构造设计以及过流部件资料的选择直接关系着泵运转的效率、牢靠性和运用寿命。

(1)泵为单级单吸式离心泵,该方式在理论中已证明特别适用于FGD装臵吸收塔循环泵保送磨蚀性、腐蚀性浆体。

(2)叶轮、耐磨板不采用口环密封方式,口环的设臵将会被浆体快速磨损,从而招致泵的效率快速降落。

(3)具有轴向调理构造,叶轮能便当轴向调理坚持叶轮与前盖板与耐磨板的间隙,从而坚持泵的高效率。这是一直坚持泵高效运转的最烦琐和最有效的方法。

(4)泵的布臵方式为“后拉式”构造。这样可使泵在拆卸叶轮、机械密封和轴组件时无须拆卸泵的进出口管线。

(5)轴承采用稀油光滑。轴承装置在有橡胶密封圈辅助密封的可拆卸轴承盒内,避免污物和水进入。

(6)泵轴为大直径、短轴头,能够减少轴在工作中的挠曲,从而延长密封的运用寿命。

Desulfurization pump is mainly used in some enterprises with fierce pollution, such as some large-scale thermal power plants, because most of these power plants use relatively mature technology to stop flue gas desulfurization. This method is relatively simple, so it is the most common. Then I will introduce to you the structural characteristics of the desulfurization pump. When the working pressure of the pump is above 0.5MPa, PTFE packing or carbon fiber PTFE packing can be used.

The circulating pump of absorption tower is a large-scale key equipment in the installation of flue gas desulfurization, which requires high reliability and service life. More than half of the electricity consumed by FGD installation is used to drive the absorber circulating pump. Therefore, the circulating pump should have high efficiency. The hydraulic design, structural design and the selection of flow passage component data of the pump are directly related to the efficiency, reliability and service life of the pump.


(1) the pump is a single-stage single suction centrifugal pump, which has been proved in theory to be particularly suitable for FGD absorption tower circulating pump to ensure abrasive and corrosive slurry.

(2) the impeller and wear-resistant plate are not sealed by the port ring, and the setting of the port ring will be quickly worn by the slurry, thus causing the efficiency of the pump to drop rapidly.

(3) with axial conditioning structure, the impeller can easily maintain the clearance between the impeller and the front cover plate and the wear plate, so as to maintain the high efficiency of the pump. This is the most cumbersome and effective way to keep the pump running efficiently.

(4) the pump is arranged in a "pull back" structure. In this way, it is unnecessary to dismantle the inlet and outlet pipelines of the pump when disassembling the impeller, mechanical seal and shaft assembly.

(5) the bearing shall be smooth with thin oil. The bearing device is in the removable bearing box with rubber seal ring auxiliary seal to prevent dirt and water from entering.

(6) the pump shaft is a large diameter and short shaft head, which can reduce the deflection of the shaft in the work, so as to extend the service life of the seal.
