Product Description
LW700 Type Oilfield Drilling Mud Decanter Centrifuge for Drilling Waste Management
Mud water is a suspension of water containing a certain amount of fine mud particles. The characteristics of the mud depends on its composition, and the local geological conditions, generally have the following characteristics: Appearance: khaki, uniform and sticky, long time still not stratified, the proportion: 1.20-1.46; (which the proportion of sand and sand 1.6) , Mud content of 20% -30%, PH value: 6-7. These muds from the construction of single pile, sand, tunnel caves, mine tailings and so on.
Mud Decanter Centrifuge Host Structure and Working Principle
Centrifuge host by the drum, auger, large support plate, small end support plate, differential, the main drive motor, auxiliary drive motor, hydraulic coupling, bearing, rotating body shield, transmission shield, Transmission belt, control box and base and other components. The drum and the propeller are the core components of the centrifuge, and the solid phase separation of the drilling fluid is carried out here.
When the centrifuge is working, the drilling fluid enters the centrifuge through the inlet pipe. Under the centrifugal force field, the drilling fluid forms a liquid circle on the inner wall of the drum. The density of the solid phase is thrown into the outer layer of the liquid, firmly attached to the inner wall of the drum to form a solid layer, the density of the liquid phase and suspended colloidal clay in the liquid inner layer. The propeller scraper scraves the solid phase layer affixed to the inner wall of the drum to the small end dewatering zone. The solid particles in the dewatering zone are squeezed and dehydrated by the centrifuge, extruding all the free water and then being helix The propeller is discharged to the small end of the bottom nozzle. The liquid phase of the liquid inner layer enters the circulatory system from the large end of the overflow hole.

Product Structural Features
1, small diameter ratio of large difference: the use of large aspect ratio, low speed, large differential; centrifugal dewatering treatment of mud with automatic continuous closed operation, without adding flocculants, strong field adaptability.
2, adapted to the bad scene:
① not afraid of the wind and sun: the scene changes in environmental temperature, the air there is a lot of dust;
② not afraid of overload impact: changes in mud composition, feed flow fluctuations, requiring centrifuges to be sufficient power margin, there are perfect protection measures.
③ not afraid of sediment wear: drum solid particles (sediment) like a grinder wear the same parts of the contact, requiring these parts have a high enough anti-wear ability;
④ is not afraid of electrical interference; site high-power equipment frequently from / stop, a variety of electrical operation is the arc, resulting in power supply voltage fluctuations, harmonic interference may damage the instrument;
⑤ not afraid of wrong operation: some workers are not high level of culture, centrifuge electrical operation to be less, the operation should be simple, control program design to fault-tolerant.
3, high precision variable speed stepless adjustable technology: common differential speed adjustment system on the differential shaft applied braking torque, the energy can not be recycled, the control system can be directly recovered energy; dynamic response fast; speed Wide range; easy to deal with sudden events caused by the accumulation of material within the drum synchronization phenomenon.
4, reasonable main speed configuration: to meet the requirements of the process under the premise of choosing a reasonable master speed configuration is conducive to improving the service life of the centrifuge.
5, high wear resistance:
According to different circumstances, the key parts of the use of carbide and drum anti-wear technology design.
① spiral tungsten carbide nickel-based alloy powder spray;
② Carbide Outlet;
③ welding of tungsten carbide electrode;
The practical application proves that the surface of the cemented carbide can increase the life of the screw conveyor by more than five times
Product Performance and Use
1, the main components of the centrifuge drum, screw propeller, the size of the support plate, shaft and upper and lower boxes are made of high quality stainless steel. To extend the service life of the propeller, in the spiral propeller outside the surfacing carbonized tungsten powder, the main bearing Swiss imports of high-quality bearings to ensure that the centrifuge long life. Adapt to the harsh conditions of the drilling site.
Differential structure is reasonable, long life.
2, the differential with two 2K-H planetary gear train in series, the differential slip according to the liquid in the roller when the stay
, Between 65-80: 1, the propeller hysteresis.
3, the use of good results
Combined with years of experience in the development and production of centrifuges, and after a large number of field experiments, we LW450 / LW600 / LW700 series centrifuge settlement parameters and feeding methods were optimized design, so that the centrifuge greatly enhance the effect of sand removal. By improving the centrifuge rotary part of the processing accuracy and dynamic balance accuracy, so that the centrifuge vibration, noise down to a very low level. After years of field application, in the Liaohe Oilfield, Dagang Oilfield, Shengli Oilfield, Zhongyuan Oilfield, North China Oilfield achieved remarkable results, widely recognized by the oil field.
