Differential as the important part of decanter centrifuge,GN always use high quality part to keep equipment running stable
GN’s decanter centrifuge through the body of revolution (drum and spiral) high-speed, produce thousands of times the gravitational acceleration, rotating through the inlet into the body of solid, liquid layered material quickly, and through the differential of this device, the relative speed of revolving drum and spiral, the solid launched by decanter centrifuge solid phase, liquid flowed from machine, to achieve the effect of solids&liquid separation.
The differential in a horizontal spiral centrifuge is to ensure that the drum and spiral rotate at different angular speeds and achieve the best differential.
Differential
There are three kinds of differential transmission, planetary differential and hydraulic differential.
The cycloid differential compact structure, convenient installation, but the output torque is small, the applied to need big thrust separation fields such as iron and steel slag, coal mine wastewater, limitations, decanter centrifuge performance can’t running;
Planet differential relative structure is larger, the torque output is also very competitive, but when applied to the decanter centrifuge, installation dimensions of the machine performance is one sector, as the high-speed machines, even very small deviation will directly affect the quality of the performance of the machine;
Hydraulic pressure differential, complement each other, in the same size of cycloid differential case, can be output, even more than with the scope of application of planetary differential torque, because by hydraulic system to produce differential, in 1r/min to 25r/min range,can realize infinitely variable speed, greatly promoted the application of decanter centrifuge field.
GN’s 3VFD for bowl speed,differential speed,and pump capacity,and the VFD brand is ABB or SIEMENS,provide good/long service
