Product Overview: SOW split volute double suction centrifugal pumps, primarily for liquid temperature less than 105 ℃ water or physical and chemical properties similar to water. Applicable to water plants, pumping stations, power plants, water recycling air conditioning, heating and hot water circulation, industrial water supply systems, fire systems, shipbuilding, oil refining industry (general liquid) and other liquid transportation applications. Centrifugal pump driven by a motor typically, before starting the pump, the pump and suction line filled with liquid. When the impeller rotates at high speed, the impeller vanes to drive the liquid along the rotation, due to centrifugal force, the liquid left behind the impeller tip (flow rate may be increased to 15 ~ 25m / s) from the center of the impeller, kinetic energy increases. When the liquid enters the pump housing, since the volute casing of the pump flow path is gradually expanded, the liquid flow rate decreases, a part of the kinetic energy into static pressure energy, so a relatively high pressure along the liquid discharge port flows. At the same time, the center of the impeller due to the liquid being thrown out and create a vacuum, and the pressure Pa at the liquid surface is higher than that at the center of the impeller, therefore, the liquid in the suction line of the pressure differential into the pump. Constantly rotating impeller, the liquid is drawn and continuously pressed out. Due to centrifugal liquid was able to transport, mainly by centrifugal force, it is called centrifugal pump. Centrifugal pumps in the most widely used in chemical production, which is due to its wide range of performance applicable (including flow, pressure head and adaptive nature of the medium), small size, simple structure, easy operation, uniform flow, less failure, life long, acquisition costs and operating costs are low and other advantages. Thus, this chapter will centrifugal fluid mechanics as a typical example of the application to be highlighted. SOW split volute double suction centrifugal pump features: optimized design of the hydraulic model, not only the hydraulic pump has excellent performance, and no axial force (in theory) the pumps, especially large pumps running problem . SOW split volute double suction centrifugal pump body, SOW in the open double-suction centrifugal pump volute cover, SOW split volute double suction centrifugal pump impeller casting, overcurrent smooth surface improves the resistance to steam pump corrosion performance and efficiency. Packing seal or mechanical seal according to the medium or user requirements, without turning restrictions. For packing, there is enough space to replace the packing. SOW split volute double suction centrifugal pump operating conditions: 1.SOW in the open double-suction centrifugal pump volute try working pressure 2.5MPa; that pump inlet pressure + pump head ≤2.5MPa. According to withstand the maximum pressure of the pump casing, pump body and cover made of gray cast iron (1.6MPa), ductile iron (2.0MPa), steel (2.5MPa). Please specify when ordering the pump pressure or materials. 2. Medium: water or temperature ≤105 ℃ physical and chemical properties similar to water, other liquids (solids ≤80mg / L). SOW in the open double-suction centrifugal pump volute structural characteristics: SOW split volute double suction centrifugal pump is compact, good stability. This type of pump is the pump housing open structure, import and export are on the pump, just need to take out the pump cover, rotor part can be removed for maintenance work without the need to disassemble pipeline, very convenient. Required motor (driver) can also be left at the right end for easy field installation. Shorten the structure of the rotor axial dimensions, steel shaft better, more stable and reliable. There pump seal ring and impeller seal ring is an optional part. After sealing ring wear can be replaced, reducing operation and maintenance costs. 1. SOW split volute double suction centrifugal pump is lubricated by grease enclosed bearings, simple maintenance and long running time. 2. With constant oil level in the oil cup, thin oil lubrication. 3. Selection of imported (SKF, NSK, NTN) high quality bearing, smooth running, low noise, long service life.
