In explaining the performance characteristics of centrifugal pump before the industry to see what is centrifugal pump, centrifugal pump is the use of impeller rotation leaving the water centrifugal movement to work. Pump before starting, must pump shell and suction tube filled with water, and then start the motor, so that the impeller and water pump shaft to do high-speed rotary motion, the water centrifugal movement, was thrown to the outer edge of the impeller, Road into the pump pressure water pipes. Centrifugal pump performance characteristics are the following six major features.
1, energy efficient: CFD computational fluid dynamics, analysis and calculation of the pump pressure distribution and velocity distribution, and optimize the pump flow channel design to ensure that the pump has an efficient hydraulic lines, improve the efficiency of the pump.
2, easy installation and maintenance: vertical pipeline structure, the pump can be the same as the import and export of valves installed in any position in the pipeline and in any direction, installation and maintenance is very convenient.
3, smooth, safe and reliable: the motor shaft and water pump shaft for the coaxial straight, concentric high, smooth operation, safe and reliable.
4, stainless steel sleeve: shaft seal position is relatively easy to be corrosion of the Department, once the direct-type pump shaft is rusted, easily lead to mechanical seal failure. STG pump here with mosaic stainless steel sleeve, to avoid corrosion, improve shaft life, reduce operation and maintenance costs.
5, bearings: pump with the motor, Y [Y2] 280 the following shaft end bearings [including Y180 following fan end bearing] closed bearings, normal use, maintenance-free motor bearings.
6, mechanical seal: mechanical seal base pieces of rubber bellows general use of the structure, the traditional mechanical seal on the shaft seal from the O-ring line seal to rubber pieces of the two-way seal in the water when the media to improve the sealing effect.
