It is designed to meet the drilling fluids recycling for mining drilling rigs especially for diamond drilling.The diamond drilling contract can choose to buy single centrifuge unit with electric drive fixed speed or VFD drive variable speed or even the Fully Hydraulic Drive . For the FHD drive Centrifuge, it can use the diesel engine to power the hydraulic pump to feed to the centrifuge without any electric.GN also have the completed tank system with Mini Shaker for optionTech Support Southwest Petroleum UniversityProduction Standard API Q1 & ISO/TS29001 & ISO 9001:2008Stainless Steel Material Bowl , Conveyor, Main body made from Stainless Steel:SS316LAbrasion Protection Screw protected by Tungsten Carbide Tiles or Hard Surfacing.Solids Discharge Port protected by interchangeable Tungsten Carbon AlloyElectrical Components SIEMENS/Schneider/CHINT (SIEMENS VFD)Bearing Sweden SKF or Germany FAG Bearing.Explosion Proof MotorAnd Control PanelUSA UL / Europe ATEX Certified Motor option available.Normally explosion proof Mark: Exd II Bt4 ( Class I, Division I)Coating & Painting Japan Kansai Brand (Epoxy zinc rich prime, thickness 75 µ, epoxy medium twice, thickness 150 µ, polyurethane finish paint twice, thickness 70 µ)Speed Adjustable VFD drive or Fully Hydraulic Drive for variable speed.Steel International Standard Steel From Top Company(HBIS) Feeding Pump Screw pump & Centrifugal pump option available to meet different applicationGN Centrifuge Features & BenefitsOil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com3GNLW Mini Centrifuge PhotosOil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com4GNLW Mini Centrifuge DimensionsLxWxH as below1815x994x1168mmOil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com5GNLW Other Centrifuge PhotosOil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com6GN Centrifuge WorkshopOil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com0204060801001201401608 10 12 14 16 18LPMMud Weight (PPG)GNLW223VFD Centrifuge GNLW223VFDGNLW223VFD Decanter Centrifuge Data Chart Oil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com8GNLW Centrifuge Screw With Ceramics ProtectionOil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com9GNLW Centrifuge Screw with Tungsten Carbide TilesOil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com10GNLW Centrifuge Pressurized VFD Control PanelOil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com11GN 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 drum’s 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 solid’s 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.Oil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com12GN 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. Motor’s 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 coupler’s 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 120°c, 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 coupler’s working condition. Replace the oil as required.Oil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com13GN Gear Box Working PrincipleDifferential 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 tumbler’s rotating speed,and 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 gear’s 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.Oil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com14GN Centrifuge Working WorldwideGN In Australia GN In BrazilGN In Argentina GN In Middle EastOil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com15GN Beijing FactoryOil Drilling & HDD & CBMMud Solids Control & Waste Managementhttp://www.gnsolidscontrol.comOil Drilling & HDD & CBMhttp://www.gnsolidscontrol.com16(Mud Solids Control Specialist)Company name: GN Solids Control Co.,Ltd HQ Address: No.3 Industry Road,Dachang Chaobai River Development Area,Langfang,China 0 65300Tel: +86-316-5276989 / 5276988Fax: +86-316-5276997 / 5276990 Email: sales@gnsolidscontrol.comWebsite: http://www.gnsolidscontrol.com (English) ????? 1 ????? 2 ????? 3 ????? 4 ????? 5 ????? 6 GNLW223VFD Decanter Centrifuge Data Chart ? ????? 8 ????? 9 ????? 10 ????? 11 ????? 12 ????? 13 ????? 14 ????? 15 ????? 16
