8. PLC remote control(Customer selection)
Structures and properties
This machine is horizontal spiral discharging settling centrifuge, the main machine has a column-cone bowl, spiral stoker,
differential system, bearing seat, base, cover, main motor,vice motor, and electric control chamber. With the high speed rotating of bowl, form strong centrifugal force, making the sludge dehydrate continuously in 24 hours a day.
The main motor through the triangle belt make the bowl rotating, through the planetary gear differential, make the vice motor and spiral differential speed different, realize sludge dewatering and pushing material function, That means differential rotating speed control and torque control. because containing solid rate of sludge may have wave motion, by differential speed control system is the guarantee for speed stability, achieve solid content in sludge is constant, the constant torque control make decanter load in a stable state, the separation effect and flocculation is the best state, so as to ensure the safe operation of the centrifuge.
It has good seal performance (guarantee without material leak in the process of operation), sludge dewatering work in full seal state, makes the environment clean.
This machine adopts the most advanced international special structural design, especially the spiral stoker, make the sludge concentration dehydration integration characteristics. It has better performance than ordinary centrifuge, more high capacity, better separation effect, save energy and manual work.
It is widely used in the production of chemical, printing, metallurgical coal mine, oil production, metallurgy,iron and steel, fabric, food, drink, dyes and so on, and it can also solve industrial and municipal wastewater. By use it, solid can be dehydrated, liquid can be clarified. The application of horizontal screw decanter centrifuge in environmental protection mainly refers to the dehydration of sludge produced in the process of industrial and civil sewage treatment. Nowadays, environmental problems have become the focus of the world. In this context, the value of horizontal screw decanter centrifuge has been reflected. Because of its inherent characteristics of large processing capacity, automatic operation and good dehydration effect, horizontal screw decanter centrifuge has been widely used and promoted in the field of environmental protection. Horizontal screw decanter centrifuge is the preferred equipment for sludge dewatering.
1.We will provide one-year warrantee to make sure your machine runs consistently.We always keep certain inventory level of spare parts,which means the replacements can be shipped to you right away.
2. Consultant services for whole machine life,24 hours technical support by email and telephone.
3. Send technicians to the jobsite for guiding the installation and adjustment,training operators and finishing the check and accept together with you.
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 such as SKF,FAG and so on.
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.
