XOH2系列重工位石化流程泵是在吸收国内外先进的石化泵应用经验基础上，根据美国石油协会API610第11版《石油、重化学和天然气工业用离心泵》和API682《离心泵及回转泵轴封系统》设计规范，结合我公司专有技术设计的卧式、单级、单吸离心泵。该泵完全符合OH2泵型特点，壳体为径向剖分、中心支撑。
XOH2 serial standard petrochemical process pump refers to the horizontal, single-stage and -suction centrifugal pump designed based on absorbing international advanced experience in petrochemical pump application and according to design standards of API610 11th edition of Petroleum, Heavy Chemistry and Natural Gas Industrial Centrifugal Pump and API682 Centrifugal Pump and Drum Pump Shaft Seal System and by combining our company’s proprietary technologies. The casing is radial direction and central support.
结构特点Structural characteristics:
1、叶轮采用平衡孔加密封环平衡轴向力，出口直径80mm以上的泵体设计成双蜗壳平衡径向力，保证了轴承的使用寿命和轴封处轴的挠度；
Balance pipe and wearing ring balancing axial thrust is adopted for impeller. Double-volute balancing radial force is designed for pump with outlet diameter of above 80mm. Thus, the service life of bearing and axial deflection of shaft seal;
2、轴承架全部为铸钢件，泵体和轴承架可采用中间连接段连接，在输送高温、高压、易燃、易爆或强腐蚀性的介质时，中间连接段可采用不同的材质，以避免轴承架断裂或被严重腐蚀。
Bearing support is steel casting. The connecting piece between pump and bearing support is connected. When mediums with high temperature and pressure, combustibility, flammability and strong corrosion are transported, different materials can be used for connecting piece to avoid fracture or severe corrosion of bearing support.
3、按API682标准密封腔设计，采用集装式机械密封，便于安装和维修，轴向压缩量不受任何连接件轴向尺寸影响，无需调整。
Packaging-type mechanical seal is adopted according to seal design of API682 standard. It is convenient in installation and maintenance. The axial compression is free of influences of axial dimensions of any connecting pieces. It is not necessary to make adjustment.
4、采用新型非金属同步甩油环，润滑更加充分，并减少润滑油污染；配套专用轴承压盖，可满足油雾和油浴润滑的双重需要。
With new-type non-metal synchronic oil slinger, it is further sufficiently lubricated and pollution of lubricating oil is reduced. With special bearing gland cover, dual requirements of oil mist and bath lubrication can be satisfied.
5、管口按API标准三倍载荷设计，采用API标准底座，确保运转安全、稳定、可靠。
Pipe orifice is designed according to API standard triple load. API standard
chassis is adopted to ensure safe, stable and reliable operation.
6、采用40度角接触轴承，完全符合API610第11版要求。
With 400 angular contact bearing, API610 11th edition’s requirements
can be completely satisfied.
7、选用锻造增强型刚性轴，符合API610的典型设计方案；
With enhancement rigid axle, typical design scheme of AIP610 can be met.
8、加厚壳体设计，符合API要求的3mm腐蚀余量。
With thickened casing design, 3mm corrosion allowance required by API can be satisfied.
