Main Technical Feature:

1. Industrial Design
Whole machine set design follows concept of advanced industrial design,ensures stability,functionality and safety of whole machine.Also effectively absorbs shear force of dynamic load during operation.

2. Effectively Ease Resonance During Rotating Of Bi-Rotor
When centrifuge works,there is no obvious first-order and two-order resonance regions within designed speed range,meanwhile ,whole vibration intensity of bearing seat is definited within 2mm/s-4mm/s.All of this eliminates extra fatigue damage to components and assembly units from high frequency vibration during operation and sudden vibration when shut down.

3. Thoroughly Eliminate Phenomenon Of Liquid Ring Stalling
Phenomenon of liquid ring stalling happens during heavy duty boot or shutdown process of complete set machine,especially for LW550 and even larger models,It would makes bounce or wild shake,causes extra impact fatigue damage to main bearings,screw bearings and inner parts of rotary bowl.Fortunately ,our engineers have solved this problem thoroughly.

4. Unique Technique Adopt In Main Component Work-Blanks
The manufacturing methods of main component work-blanks are adopt centrifugal casting technique and overall mould-making forging technique,thoroughly avoid risks such as inter-granular corrosion and relaxation of residual stress release in welding joint.

5. Main Bearing Selection
We use origin bearings of international first-line brands .

6. Constant Temperature Detection
All fashioning components and assembly units are detected in constant temperature condition,to make sure of actual processing quality meets the requirements of designed precision accuracy.

7. Inter-Change Ability
Whole machine physical design and processing technique adopted in critical position,ensure all assembly units and bowls of the same centrifuge model interchangeable.It is not only easy to maintain ,but also greatly improve the reliability and safety of equipment.

8. Simplyand Safely In Bearing Disassemblement
One layer of oil film is injected into contact surfaces between bearing and work-piece by high-
pressure,during disassemblement bearing from the machine.which would fundamentally eliminate friction within different parts.As a result,it would reduce 90% of pulling force and lower the risk of damage to high-precision parts when disassemble bearing.

9.Main Bearing Lubrication System
There are two kinds of lubrication system for specific product models : A Thin Oil Lubrication
* Oil pump offers an uninterruptedly power to ensure oil works circularly;
* Jet oil lubrication constantly clean and lubricate bearings and reduce temperature;
* Oil filter system ensure lubricant's cleanliness;
* Oil pressure energy storage system ensure lubrication pump offers an extra oil supply(the pressure is no less than 0.4Mpa) for 5-6 minutes,when power fails accidentally;
* Constant temperature system is available.

B Grease Lubrication
* Adopt a grease with properties of extreme pressure resistance ,oxidation resistance ,abrasion resistance,water scour
resistance,corrosion-proof and high temperature resistance.
* Optional automatic grease system fills grease on main bearing at designed hours and quantity.

10. Main Bearing BH Device (Patent Design)
There are two spare safe bearings at either end of main bearing.When machine works well,they keep certain clearance from bearing inside track to chief axis.When unexpected condition occurs,main bearing got damaged or circle center deviation causing an amplitude of vibration reaches to designed clearance,safe bearings begin to work as main bearing Meanwhile,computer automatic control system would get a feedback of abnormal vibration value on bearing position immediately then activates emergency shutdown and goes a smooth shut down.This system protects machine free from damaging and ensure production safety.

11. GSRL Feeding Device (Potent Design)
New design of internal spiral core tube has got following achieves.Without reducing centrifugal acceleration,shorten triangle belt's traction time,reduce disorder of swirling flow and extend separation time.Meanwhile increases inner working pressure of centrifuge,and restrains liquid foaming.

 

 

Operating Principle 
 

Working Procedure
Decanter can use limit space to fit together different stages of separation.

Mixing And Accelerating Stage
Sludge and chemical mixes in the specially designed feed chamber and accelerates together. This prepares the sludge for best separation.

Clarifying Stage
The flocculants sediments inside the bowl under centrifugal force, the clear liquid flows out of the weir an the end of the bowl.

Pressing Stage
Conveyor pushes the solid toward the discharge end. The sludge is further pressed by centrifugal force and the water comes out of the small holes of the sludge

Double-Direction Pressing Stage
In the conical part of the bowl wall, the sludge is pressed by specially designed double direction pressing effect. The specially designed conveyor produces axial pressing force and water comes out of the tiny holes of the sludge.
Control the Staying Time of Solid In order to achieve best dewatering effect when flow rate or character of sludge changes, the solid content inside the bowl should be continuously controlled.This is controlled by the drive system of the conveyor. The drive system of the conveyor can measure real-time the solid content inside the bowl and adjust automatically, solid discharge torque automatically compensated

Drive Technology
The reliable and excellent operation needs good cooperation of bowl drive and conveyor drive, Shanghai Centrifuge Institute researches good drive combination, which can be recommended as best design to suit different applications.

 

Bowl Drive System Alternatives Includes:
AC Motor+ Frequency Converter
AC Motor+ Hydraulic Coupling
Other Special Ways
Conveyor Drive System

Separation Technique
Feeding-gravitational separation-liquid discharge-sediment discharge.
Separation effect factors Centrifuging factor ,length to diameter ratio of cavity ,depth of fluid pool.
