I. General Description
Centrifuge Model LW355×1257-N for separation of detrital material of drilling muds is widely used in solid control system for drilling mud to separate the solids phase of mud, remove harmful fine drill solids such as debris, etc. in the mud fluid, or recover weighting materials such as barite etc. so as to reduce the cost of mud fluid.
LW355×1257-N centrifuge provides two drive modes: rated frequency drive and variable frequency drive. As to rated frequency drive centrifuge, the rotating bowl speed is fixed, so the speed can be changed only by changing drive pulley; while variable frequency drive centrifuge can achieve large-range stepless speed regulation easily with parameters displayed, e.g. speed and working current.
XBSY Centrifuge provides solutions to all technological problems of
solids-liquid and liquid-liquid separation, specialized in
industrial centrifugal separation markets. These solutions help
customers to clarify, concentrate, and separate products in
production.
Centrifuge Bowl and screw conveyor are made of stainless steel (No. 304/316) for high resistance to wearing and erosion.
Over 400 sets are widely used in overseas market including United
States, Russia, South America, Middle Asia and Middle East. With 7
patents given including a special controller for flow ajustment.,
Screw conveyor are bonded with hard alloy blocks that improves the
service life up to 5 years..
Max through capacity up to 80 m3/h (SG<1.1)
It is a large-displacement model with high rev. and large treatment
volume developed by us and a unique model among domestic petroleum
drilling fluid-purpose centrifuges.
IIi. Circumstance Conditions:
Ambient temperature: -20°C～+50°C
Relative humidity of ambient air: ≤95%
Explosion protection mark: ExdⅡBT4
Corrosive environment: No active gas or steam that will destroy the metal
Degree of electrical protection: IP54
A. Cranes and slings can not bear excessive load, regular check shall be given to the slings so as to ascertain whether they are in good state.
B. The sustained centers shall be checked before lifting to ensure that the strength of the sustained centers meet the requirement of hoisting.
C. Make sure the installation platform is firm enough to bear adequate weight.
A. All safety protection guards shall be installed before starting up.It is forbidden to open the guards to observe the running state of the machines.
B. During the operation of the centrifuge, touch to moving parts and rotation parts should be avoided.
C. It is forbidden to brake in any way before the equipment is stopped.
D. If there is abnormal noise and vibration, close down immediately and make troubleshooting.
E. It is forbidden to have the machine running at the rotating speed out of active speed that indicated in the instruction and nameplate.
Only after power is cut off can electrical devices be wired or plugged/unplugged!
3. Maintenance
A. Only after power is cut off and bowl stops completely running can the machine be dismantled and adjusted.
B. When opening the cover of vessel, it should be opened sufficiently and be fixed to prevent the sudden closure of the cover and injure the operators.
