    GN Centrifuge Working PrincipleSeparation of solids and fluid is done in the drum. Its principle is : high-speed rotating drum drive inner mud rotate speedily and then the mud is thrown onto drums surface to form a fluid circle. Under the centrifugal force, solid sedimentary force in the separated liquid will be several hundred even thousands of times heavier than its own gravity so as to separate the solids from the suspension quickly. The ratio of centrifugal force which the solids have gained and the solids gravity is called as separating factor. The larger the centrifugal force, the finer the separated solids, so three types of centrifuge can get according to separating factor.

    GN Hydraulic Coupler Working PrincipleHydraulic coupler is mounted on main motor, it is a hydrodynamic transmission device, it have the function of buffering starting shock, reduce starting current and overload protection. Its structure is in Figure 6, it consists of shell, turbine, pump wheel, input shaft, output pulley; shell is joined with turbine, output pulley connect with shell; input shaft connect with pump wheel, working oil is filled into the shell, pressure emerges in service oil caused by centrifugal force when motor axle drive turbine to rotate, in this way, power is transmitted. Motors no-load starting can achieve when motor start-up in lower speed because less liquid pressure and smaller drag exist at this time when reaching its rated rotational speed, oil pressure increase and drive load to rotate, this is couplers buffering starting shock principle; When load is too heavy, speed differential between pump wheel and turbine increase , oil is heated immediately, melt able plug in the coupler will be melted when oil temperature exceed 120c, oil sprays out to make input separate from output, thus main motor is protected and make sure no burn occurs, oil is the media of transmission, so its performance will influence couplers working condition. Replace the oil as required.

    GN Gear Box Working Principle

    Differential gear in fact is a secondary planet slowdown gear, there is ring gear in the shell internal processing. the shell is rotated with the roller, the left belt pulley drives the first sun gear on the input gear rotate, the first sun gear engaged with the ring gear of the shell through the first planet gear, by doing this, the shell rotating speed and the input bearing rotating speed combined into a first tumblers rotating speedand the secondary sun gear output the combined speed to the second part, the transmission principle of the second part is the same with the first one, and finally drives the screw propeller rotate through the output bearing.

    In order to protect the differential gear from shattering when the centrifuge is over loaded, security equipment is also installed in the differential gears left end, security pin is installed on the gear shaft, the dynamic force transmitted from the belt pulley is transmitted to the catch plate through teeth socket ,then sent to the cam, the cam send the dynamic force to gear shaft through security pin. When the torsion torque exceeds the intension of the security pin, the security pin will be cut down and disconnect the transmission so as to make a protection. Note: because of the reliable overload protection of the overload of the centrifuge, limit switch is not installed on the high speed frequency converted type centrifuge.
