DESCRIPTION
This equipment is a LW series product, commonly used for dehydration and concentration. Widely used for maximum dewatering requirements of municipal and industrial wastewater sludge. It is characterized by small size, high rotational speed, and small processing capacity, and is used in situations where large separation factors and small processing capacity are required.
According to practical use, it can be divided into: clarification type, dehydration type, concentration type, separation type,
classification type, extraction type; Users can choose by themselves. Dehydration horizontal spiral centrifuge is suitable for easily separated materials with large particle size, large solid-liquid density difference, low viscosity, high concentration, strong processing capacity, and higher dryness than clarity. Materials such as sludge or wastewater containing fine particles usually require the addition of flocculants to condense the fine particles into large particles, which are then dewatered using a sedimentation centrifuge.
The horizontal screw centrifuge relies on the density difference between the solid and liquid phases to accelerate the
sedimentation rate of solid particles under the action of centrifugal force to achieve solid liquid separation. The centrifuge
consists of two rotors, one called a drum, and the other rotor is a screw discharger (referred to as a screw). When the drum rotates at a high speed, the slurry inside the drum rotates with the drum and is subjected to a centrifugal force that is many times greater than gravity. In this way, solid particles will be separated from the liquid and settle onto the inner wall of the drum from the centrifuge drum shaft. The screw discharger located inside the drum rotates at a speed lower than the drum and pushes the deposited solid particles to the slag outlet, The differential rotational speed between the outer drum and the screw discharger depends on the transmission ratio of the differential and its rotational speed.

The advantages of our product
1. Industrial design
The whole machine set design follows the concept of advanced industrial design, ensuring the whole machine's stability, functionality, and safety. Also effectively absorbs the shear force of dynamic load during operation.
2. Effectively ease resonance during the rotating of bi-rotor
When the centrifuge works, there are no obvious first-order and two-order resonance regions within the designed speed range, meanwhile, the whole vibration intensity of the bearing seat is definitely 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 the phenomenon of liquid ring stalling
The phenomenon of liquid ring stalling happens during the heavy-duty boot or shutdown process of a complete set machine, especially for LW550 and even larger models, It would make a bounce or wild shake, causing extra impact fatigue damage to main bearings, screw bearings, and inner parts of the rotary bowl. Fortunately, our engineers have solved this problem thoroughly.
4. Unique technique adopts in main component work-blanks
The manufacturing methods of main component work blanks adopt the centrifugal casting technique and overall mold-making forging technique, thoroughly avoiding risks such as intergranular corrosion and relaxation of residual stress release in welding joints.
5. Main bearing electrical components selection
We use the origin bearings of international first-line brands such as S-K-F, F-A-G, etc. Electrical components mainly adopt ABB and Siemens
6. Constant temperature detection
All fashioning components and assembly units are detected in constant temperature conditions to ensure that 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 are interchangeable. It is not only easy to maintain, but also greatly improves the reliability and safety of the equipment.
8. Simply and safely in bearing disassemblement
One layer of oil film is injected into contact surfaces between the bearing and work-piece by high-
pressure, during the disassemblement bearing from the machine.which would fundamentally eliminate friction within different parts. As a result, it would reduce 90% of the pulling force and lower the risk of damage to high-precision parts when disassembling the bearings.
9. Automatic main bearing lubrication system
Thin oil lubrication
* Oil pump offers uninterrupted power to ensure oil works circularly;
* Jet oil lubrication constantly cleans and lubricates bearings and reduces temperature;
* Oil filter system ensures 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.
* Adopt a grease with properties of extreme pressure resistance, oxidation resistance, abrasion resistance, water scour resistance,corrosion-proof, and high-temperature resistance.
* Automatic grease system fills grease on the main bearing at designed hours and quantity.
10. Main bearing BH device (patent design)
There are two spare safe bearings at either end of the main bearing. When the machine works well, they keep a certain clearance from the bearing inside the track to the chief axis. When an unexpected condition occurs, the main bearing getting damaged or circle center deviation causing an amplitude of vibration reaches to designed clearance, safe bearings begin to work as the main bearing Meanwhile, the computer's automatic control system would get feedback of abnormal vibration values on the bearing position immediately then activates emergency shutdown and goes a smooth shut down. This system protects the machine free from damage and ensures production safety.
11. GSRL feeding device (potent design)
The new design of the internal spiral core tube has got the following achieves. Without reducing centrifugal acceleration, shorten the triangle belt's traction time, reduce disorder of swirling flow, and extend separation time. Meanwhile increases the
