VFD Control Panel

This week 2 units of VFD decanter centrifuge ready for shipment to India for ONGC project in GN factory. The clients ordered 2 units of GNLW453C-VFD with screw pump for their solids control system with their customized painting color.


GNLW453C-VFD centrifuge with 18inch bowl and 61inch length, the max G force is up to 2578G, considering the high temperature in India, the positive pressurized VFD control panel with air conditioner for cooling, in some countries with environmental temperature less than 40 degree, the VFD control panel attached cooling tube for cooling. The frequency converter of the main motor, back drive motor and pump motor is all made of ABB brand, the other electric components are also world famous brand like Siemens/ schneider/ ABB, the motor and VFD control panel are all ATEX approval and suitable for 460V/60HZ, 3 phase and apply for zone 1 application.
Features of GN decanter centrifuge:
1) Different with other Chinese centrifuge manufacturer, GN use SKF bearings, since bearing block is the most important part for centrifuge, we use more reliable brand bearing to improve the centrifuge working life and reduce maintenance cost.
2) The screw is completely made of stainless steel, the impeller is protected by tungsten carbide tiles, the fluids distribution port is protected by tungsten alloy and interchangeable.

Among
all the solids control manufacturers in China, GN Solids Control’s decanter
centrifuges are most popular and of larger technology and most advanced
patterns. GN Solids Control carries a wide range of decanter centrifuges which
will cover nearly all the programs needed for oil and gas drilling solids
control systems, drilling
cuttings waste management systems
, drilling liquid waste management methods
and for other drillings because diamond drilling and mining or prospecting.
1 . Per bowl length, GN centrifuges could be split up into big bowl centrifuge
and also normal centrifuges.
The most popular serving diameter is 14 “ diameter bowl, this product is
also GN’s best seller centrifuges. For the same bowl size, GN has 5 options for
consumers to choose from per their circumstances, economic configuration and
substantial configuration, VFD controlled and stuck speed controlled. For VFD
controlled, there are simple VFD controlled and positive pressurised control
panel available. Standard model GNLW363.

And there is baby centrifuge with one motor, only 9 inches diameter bowl, which
is considerably better for mining industry, along with model GNLW223.
Big pan centrifuges cover the types of bowl diameter larger than 17 inch. GN
has 20 inch bowl and twenty two inch bowl sizes intended for options. For 18
” bowl, there are GNLW452 using middle speed and GNLW453 with higher
speed, while the duration diameters are different.
Normally often the bowl diameter determines the particular treating capacities.
2 . for every speed, there are different RMPs available.
For the baby centrifuge, the RPM is 4500. GNLW363 with largest RPM of 3900,
while 20 inch ones, the RPM is 1800 for GNLW452, 2800 for GNLW453 along with
2500 for GNLW553.

For buying a suitable decanter
centrifuge
regarding dewatering among GN centrifuges, 3 points should be
considered:
one high speed and larger bowl diameter/ length ratio, for example , GNLW452
has speed of 1800RPM and 2 as span diameter ratio, it is more desirable for
solids control rather than dewatering.
2 . better content, for more anti-wear, GN substantial configuration
centrifuges are much better.
3. VFD control
panel
is preferred for prospects to choose suitable speed each condition.
In most cases, GNLW363CG-VFD is actually chosen as dewatering centrifuge for GN
clients.
