Product Description

LW ZHorizontal Decanter Centrifuges

LW application:

It is widely used in solid-liquid separation, dehydration,clarification and classification of suspension in chemical industry, light industry, environmental protection, pharmaceutical, food, oil mining and other industries.

LW Characteristic

1. Wide scope of application: For suspensions with solid mass content≤ 50%, liquid-solid volume concentration ≤ 75%, liquid-solid weight difference ≥0.05g/cm3, the equivalent diameter of solid particles ≥ 5μm can generally be separated, dehydrated, clarified and classified. When the difference between solid phase and liquid phase is large, the equivalent diameter of solid particles (≥2μm) can also be separated.

2.High degree of automation: the machine is continuous feeding, continuous discharging. Under the action of centrifugal force, solid particles are continuously pushed to the small end of the drum by helix, and the clarified liquid is continuously discharged from the large end overflow port along the spiral groove, thus realizing continuous automatic operation.

3.The machine has compact structure, small floor area and convenient installation and maintenance.

4.Convenient adjustment: The machine is equipped with advanced frequency converter. As a result, when compared with similar products, the machine has the advantages of low energy consumption and stepless adjustable working speed. The diameter of overflow plate and differential speed can be adjusted according to material properties.

Horizontal Decanter Centrifuges feature continuous feeding and discharge . This chemical separation equipment has been applied two-phase(solid-liquid) and three-phase(solid-liquid-liquid) slurries separation industry of chemicals, pharmaceutical, environment protection, as well as mining and food, etc.

The advantages of our product

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 electrical components selection
We use origin bearings of international first-line brands such as S-K-F,F-A-G and so on.Electrical components mainly adopt ABB and Siemens
 
 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
