SB-S type shaft open single stage double suction centrifugal pump, is the company in more than 40 years in the centrifugal pump technology and engineering application of another innovation. The result is characterized by: the original high efficiency and energy saving can be quickly disassembled invention patent product single suction centrifugal pump head range extended to more than 90 meters, fully meet the large flow, high head, and at the same time reduce the axial force and radial force of the user requirements.

　　1, SB-S type shaft open single stage double suction centrifugal pump has the same double suction impeller as the conventional horizontal centrifugal pump to balance the axial force of the pump, and the use of shaft open structure is more advantageous than the horizontal middle open structure, in terms of floor space and easy assembly and disassembly; On the other hand, due to the use of dual pump

　　time-tested double vortex shell patent technology, can effectively eliminate the radial force. Therefore, the unit is in a nearly perfect state of force balance operation, its reliability, stability and noise indicators are better than other similar products.

　　2, this type of double suction pump inlet and outlet is flat into the L-shape, especially suitable for the configuration of empty water supply pipeline pump room, simple and reasonable, than flat into flat out in the open double suction pump covers an area of about 50%, the bending pipe is reduced by 1 ~ 2, saving labor and materials, but also improve the efficiency of the device; In addition, this type of double suction pump still maintains the consistent characteristics of the dual pump, the fixing of the pump does not need to pour concrete foundation and anchor bolts, just on the hard flat ground, in the pump chassis pad into the 8 ~ 10 thick 18 mm rubber shock pad, should also be installed in the water inlet pipe a soft connection (water pipe is not installed). The two degrees of freedom maintained by the linkage of the pad and the soft joint are

　　enough to effectively ensure the smooth operation of the pump and reduce noise.

　　3. The span of the bearing at both ends of the pump shaft is reduced

　　by about 1/3 compared with the general open-type double-suction pump, and the rigidity of the pump shaft is greatly increased, which improves the smoothness of operation. At the same time, in order to improve bearing lubrication conditions, replace ordinary grease lubrication with automatic oil replenishment type oil lubrication device, and the oil level is visible and controllable, to ensure the best lubrication state of the bearing, small friction resistance, fast heat dissipation, significantly improve operation reliability and bearing life.

　　4, the general replacement of the machine seal needs to disassemble the bearing first, and the bearing after several disassembly, its accuracy is reduced, the life is shortened. To this end, the pump is to place the machine seal in the left and right inlet passage, a large number of overflow fully improve the cooling state of the machine seal, so that the heat generated by the friction pair instantaneous loss. Compared with the sealing cooling system of the open-type double-suction pump that can only take the backwash pipe, it is not only high volumeefficiency but also good working conditions, which is undoubtedly conducive to improving the sealing life and is expected to synchronize with the bearing life in about 25000 hours.

　　5, in order to facilitate the installation and disassembly, the use of disassembly type three-section coupling, just remove the middle coupling, do not need to move the motor or pump body can be carried out the operation, and the installation and disassembly of bearings only with special tools can be completed, do not need or should not be knocked and other damaged bearings non-standard operation, disassembly both ends of the bearing and the seal, by one person operation, about an hour can be easily completed.

　　6, the two ends of the bearing gland outer surface of the lower end of the small semi-circle paint red paint, to indicate the internal oil level, when found that the transparent oil cup about 120 ml of oil is reduced by most as long as the oil cup with the oil can be filled, it is best to use the car SN0W30 or SN5W40 oil.

　　7, from the motor back to the front, this double suction pump has a left water inlet and right water outlet or right water inlet and left water outlet two kinds of optional, once selected must be in the supply contract a single marked water inlet left or right can be.

　　8, SB-S type water pump performance range: Flow 1000 ~ 5000m 3 /h, head 20 ~ 160m;

　　Inlet diameter 500(mm), outlet diameter 450(mm);

　　Pump body pressure 1.6MPa; Special pressure 2.0MPa; Working condition water temperature t:

　　Pump inlet pressure ≤1kg/cm 2 , t≤80℃; Pump inlet pressure ≥4kg/cm 2 , t≤135℃;

　　Motor power 160 ~ 1800KW, of which, 355KW below, with national

　　standard YE3 type; More than 355KW, with Y2 or YKK motor; Can also be customized according to the user's choice; Motor collocation voltage 380V, 660V, 6KV, 10KV four kinds of options.
