Offshore Drilling Mud Centrifuge and Cuttings Dryer to Asia Oilfield Service Company

Recently one batch of offshore drilling mud centrifuge and cuttings dryer are ready for delivery to Asia oilfield service company. The equipments list is as below：


1. 6 units of GNLW363D-FHD Fully Hydraulic Drive decanter centrifuge
2. 2 units of GNCD930G vertical cuttings dryer with skid


3. 8 units of variable speed screw pump, 2 units as flushing pump for vertical cuttings dryer, 6 units as feeding pump of fully hydraulic drive decanter centrifuge
The features of GNLW363D-FHD Fully Hydraulic Drive decanter centrifuge including:


1. ATEX motor and control panel, the cable meets the requirements for use in marine environments.
2. The hydraulic bowl and scroll drive system drived both the hydraulic motor ROTODIFF and the bowl of the decanter centrifuge from hydraulic pump unit by two hydraulic oil circuits.
3. The centrifuge can be used for high temperature ambient up to 55 C degree for heavy mud, suitable for zone 1 and zone 2 application.
4. VISCOTHERM Fully hydraulic drive system
5. Max speed is up to 3600rpm, max G force is up to 2610G.
6. The bowl material is duplex stainless steel SS2304 from centrifugal casting, the screw material is stainless steel 304.
7. The solids discharge port and fluids distribution port is protected by tungsten carbide inserts, the screw is protected by tungsten carbide tiles
8. The bearing is SKF brand
During centrifuge working process, the bowl speed ,differential speed, fluids pool depth, feed rate, flocculant consumption can be adjusted according to actual situation. The higher bowl speed, the drier solids discharge, more clear liquid effluent to be get. The lower differential speed, the longer time of the solids phase stay inside the bowl, so the discharged solids will be drier.

Fully Hydraulic Drive Decanter Centrifuge GNLW363D-FHD for Asia Customer

Recently 6 sets of fully hydraulic drive decanter centrifuge GNLW363D-FHD are ready for delivery for Asia customer.
The fully hydraulic drive decanter centrifuge model is GNLW363D-FHD, the technical configuration is as below:


Bowl size and bowl length is 14 inch by 50 inch, the max speed is up to 3600rpm, the max capacity is up to 200gpm, the main motor power is 45KW, the driving system is VISCOTHERM Fully Hydraulic Drive system. As a leading solids control decanter centrifuge manufacturer in China, GN solids control can produce different size and different type decanter centrifuge, as VFD decanter centrifuge, high speed decanter centrifuge, middle speed decanter centrifuge, Fully Hydraulic drive decanter centrifuge, 3 phase decanter centrifuge, 3 phase disc separator, etc. Especially for the FHD centrifuge, both of the bowl and scroll are drived by hydraulic motor ROTODIFF and hydraulic pump unit by two hydraulic oil circuits. The advantages to use the FHD decanter centrifuge is that it can be used in high temperature ambient for heavy duty with differential speed, compared with the VFD decanter centrifuge, the FHD centrifuge can work continuously without influence of the hot weather.
