China big volume split casing pump
The China big volume split casing pump is energy-saving, single-stage, double-suction centrifugal water pump. This centrifugal double suction pump adopts the national standard design, the pump series, standardization, high degree of generalization, at the same time, in the design of a new material, new structure, can be used for a variety of media delivery.
Flow: 485 m3/hr
Head: 24 m
NPSHr: 3.5 m
Rotation: Clockwise from the driven end
Suction diameter: 250mm
Discharge diameter: 200mm
The shaft of the centrifugal pump is usually made of 45 steel and is quenched and tempered. In the pump with weak corrosive medium such as salt solution, the material of the pump shaft is used in 40Cr and is quenched and tempered. In the corrosion resistant pump, that is used to transport acid, alkali and other strong corrosive media on the pump, the pump shaft material is generally lCr18N19 lCr18Ni9Ti and other stainless steel.
Pump Mechanical seal
Mechanical seal is a pair of or several perpendicular to the axis of the relative sliding of the end face of the fluid pressure and the compensating mechanism of the elastic force (or magnetic force) to keep fit and with the auxiliary seal to seal leakage seal device.
Common mechanical seal structure consists of static ring (static ring), rotating ring (moving ring), elastic spring seat, set screw, rotating ring auxiliary ring and stationary ring auxiliary ring and other components, anti-rotation pin fixed to the gland To prevent the stationary ring from rotating.
Rotary and stationary rings can often also be referred to as compensating or non-compensating rings depending on whether they have axial compensation capabilities
The main function of the shaft of the centrifugal pump is to transfer the power, and the support impeller is kept in the normal operation of the working position. One end is connected with the shaft of the motor through a coupling, and the other end supports the impeller for rotating motion. The shaft is equipped with bearings, axial seals and other parts.
