Sulzer Pump Standard B73.1-manufacture,factory,supplier from China

In the field of petroleum and chemical industry, the most widely used international standards for centrifugal pumps are API610, ISO5199 and ANSIB73.1M/B73.2M, while the domestic standards are GB3215 and GB5656/T. These standards are described below.1.1 API is the abbreviation of the American Petroleum Institute. The purpose of API610 standard is to provide a procurement specification for the manufacture and procurement of centrifugal pumps.API610 (seventh edition) is proposed for centrifugal pumps used in oil refineries, and its standard name is Central Pumps for General Refinery Services.

CASING• Bonus casing thickness: Class 150 pumps feature Class 300 wall thickness as standard; increased reliability and maximized casing life.• Top centerline discharge for air handling, self venting.• Back pull-out design for ease of maintenance.• Integral casing feet prevent pipe load misalignment − maximized seal and bearing life.• Serrated flanges standard for positive sealing against leakage. Meets ANSI B16.5 requirements. Class 150 FFflanges standard, optional Class 150RF, 300 FF/RF.If any needs, pls contact me for quotation.

The power end features numerous reliability-,maintenance- and performance-enhancing features, including:• Double row angular contact outboard and single row, deep groove inboard bearings provide excellent axial and radialload support.• External micrometer enables accurate impeller clearance setting in 20 seconds, restoring pump efficiency.– Superior to jackscrews– Protected with O-rings• ASME (ANSI) B73.1 ductile iron frame adapter provides strength and facilitates interchangeability.• Metal-to-metal construction assures a true running and concentric shaft, extending bearing and mechanical sea

Market Overview: ANSI pumps are centrifugal process pumps that meet the standards of the American National Standards Institute (ANSI). It is the specification for centrifugal pumps for chemical process applications, and covers metallic centrifugal pump designs. The ASME B73 standard states the dimensional interchangeability requirements, configuration and design features to pump manufacturers in order to facilitate the installation, as well as to enhance reliability and safety of the pump unit. Global ANSI Pumps key players include KSB, Flowserve, Ruhrpumpen Group, etc.

Reason Analysis: Any Centrifugal pump has an optimal working range, reflected in the performance curve of the pump. The vibration of the Centrifugal pump varies with the flow rate, and usually its value is minimum near the optimal efficiency point, and increases with the increase or decrease of the flow rate. The variation of vibration with flow rate depends on the energy density, specific speed and cavitation specific speed of the pump. In general, the variation of vibration increases with the increase of energy density, specific speed and cavitation specific speed.
