英国进口脱硫泵Desulfurization pump
进口脱硫泵概述
单级单吸卧式脱硫泵，主要用作吸收塔循环泵使用，具有流量范围宽、高效节能等优点。该系列泵配有结构紧凑的X型托架，可大大节约占地空间。同时，我公司针对脱硫系统用泵特点开发了多种材料。
脱硫泵系可分为：泵头部件、轴封部件和传动部件。
1、泵头部件：
脱硫泵为双泵壳结构，即前、后泵壳带有可更换的金属内衬，包括前、后护板、护套、叶轮。前、后泵壳为垂直中开结构，其材质分别采用普通灰口铸铁、球墨铸铁或铸钢。前后泵壳用螺栓连接，后泵壳有止口与托架连接，泵的吐出口一般可按八个方位360度旋转，叶轮前后盖板带有背叶片，以减少泄漏，提高泵的使用寿命和效率，TL型泵叶轮与轴为螺纹连接，这样拆装方便些。
2、轴封部件:
轴封采用机械密封：具有无泄漏、可靠性高，适于输送贵重、有毒或强腐蚀性浆体。
3、传动部件:
脱硫泵一般采用同一系列的传动部件，包括托架和轴承组件。其泵轴直径大、刚性好、悬臂短，在恶劣的工况下也不会弯曲变形和振动，根据传递的功率不同，选用深沟球轴承、角接触球轴承、普通重型单列或双列圆锥滚子轴承。轴承采用稀油润滑（或脂润滑），轴承体两端的压盖、高速油封（或端盖、迷宫套及迷宫环）等，可有效地防止渣浆等污物进入轴承，保证轴承能够安全运行，具有较高的寿命。
进口脱硫泵结构特点：
1.采用可更换的硬质合金内衬或橡胶内衬的双泵壳结构，具有良好的耐磨、耐腐蚀性，易于维护、可靠性高。
2.后拆式结构，在不拆卸进、出口管路的情况下，方便的检查或更换叶轮与机械密封。
3.高效的硬质合金叶轮。
4.油润滑、高容量的轴承组件。
5.轴封采用集装式机械密封，寿命长，维护量少。
6.泵与驱动机直联的设计。
进口脱硫泵产品优点：
1、高效节能：
一般的杂质泵输送浆体时，其效率总是下降的，而且浓度越高，粒径越大，降低的幅度也越大。而二相流渣浆泵输送浆体时，其效率一般高于清水。这是因为泵的水力设计是以固液二相流场设计的，对清水和渣浆的输送来讲， 美国泰乐脱硫泵更适应浆体的运输，同时该系列泵的零件表面光洁度高，配合间隙小，容积效率高，综合效率比非金属泵高5%以上。
2、耐腐蚀、耐磨蚀、使用寿命长：
过流部件采用全金属高铬合金Cr30，耐磨损与耐磨蚀兼顾。表面晶间间隙小，且有优良的耐氯化腐蚀及更高的机械性能。年磨损量仅为0.56mm/年。具有使用寿命长的优点。
3、节水环保：
轴封采用机械密封方式，取代盘根加副叶轮的密封方式，冲洗水流量1m3/h即可，大大减少了工业用水。实现了节水、密封性好、无泄漏的要求。由于不采用副叶轮，使泵的运行效率提高了3%以上。同时也大大减轻了操作者的维修劳动强度。
4、可靠性高，维修方便，运行费用低。

import desulfurization pump
British imports desulfurization pump Desulfurization pump
Introduction of imported desulphurization pump
Single stage single suction horizontal desulfurization pump, mainly used as absorption tower circulation pump, with wide flow range, high efficiency and other advantages. The series pump is equipped with a compact X type bracket, can greatly save space. At the same time, our company developed a variety of materials for the desulfurization system with pump features.
Desulfurization pump system can be divided into: pump head parts, shaft seal parts and transmission parts.
1, pump head parts:
The desulfurization pump is a double pump shell structure, namely, the front and the rear pump shell can be replaced with a metal lining, including the front and rear panels, jacket, impeller. Before and after the pump shell for the vertical structure of the middle, the material were used in ordinary gray cast iron, ductile iron or cast steel. Before and after the pump shell bolt connection, after the pump shell has spigot connected with a bracket, the pump outlet can be according to the eight 360 degree rotation, around the impeller cover with the back blade, to reduce leakage, improve service life and efficiency of the pump impeller, pump shaft and type TL threaded connection, so convenient disassembly.
2, seal parts:
The shaft seal adopts mechanical seal: it has no leakage and high reliability. It is suitable for conveying valuable, toxic or corrosive slurry.
3, transmission parts:
Generally the same series of transmission components, including bracket and bearing assembly. The shaft diameter, good rigidity, short cantilever, in bad conditions will not bend deformation and vibration, according to the different transmission power, selection of deep groove ball bearings, angular contact ball bearings, ordinary heavy single or double row tapered roller bearing. Bearing with oil lubrication (or grease), both ends of the bearing gland, high-speed seal (or end cap, and the labyrinth labyrinth ring), which can effectively prevent the slurry and dirt into the bearing, bearing can ensure safe operation, high life.
Structural features of imported desulphurization pump:
1 the use of replaceable hard alloy lining or rubber lining of the double pump shell structure, with good wear resistance, corrosion resistance, easy maintenance, high reliability.
2 after the demolition of the structure, without dismantling the inlet and outlet of the pipeline, easy to check or replace the impeller and mechanical seal.
3 efficient carbide impeller.
4 oil lubricated, high capacity bearing assembly.
5 shaft seal adopts container type mechanical seal, long life and less maintenance.
The design of 6 pump and direct drive.
import desulfurization pump product advantages:
1, high efficiency and energy saving:
Generally, the efficiency of the slurry pump is always decreased, and the higher the concentration, the larger the particle size, the lower the amplitude. The efficiency of the slurry pump is generally higher than that of clear water. This is because the hydraulic design of the pump in solid-liquid two-phase flow field design, on the transport of water and slag slurry, the slurry pump is more suitable for the desulfurization of tylosin transport, while parts surface finish of this series pump is high, with the gap is small, high volume efficiency, comprehensive efficiency is 5% higher than Bifeijin pump.
2, corrosion resistance, corrosion resistance, long service life:
Through the use of all parts of high chromium alloy Cr30, wear and wear resistance. The surface gap is small, and it has excellent corrosion resistance and higher mechanical properties. Annual wear is only 0.56mm/ years. Has the advantages of long service life.
3, water conservation and environmental protection:
The shaft seal adopts the mechanical seal mode to replace the packing and the auxiliary impeller sealing mode, and the flushing water flow rate 1m3/h can be greatly reduced. The utility model has the advantages of water saving, good sealing performance and no leakage. Because the auxiliary impeller is not used, the operating efficiency of the pump is improved by more than 3%. At the same time, it greatly reduces the labor intensity of the operator.
4, high reliability, easy maintenance, low operating costs.

Flow: 4.3-9700m3/h
Lift: 1.4-88.6m
Motor power: 4-900kw
