  • How LS585 Shale Shaker Manages High Solids Content in Complex Formations

    In oil drilling operations, the geological challenges posed by deep wells, ultra-deep wells, and extended-reach horizontal wells make the stability of drilling fluid performance essential for operational safety. As drilling depth increases, formation pressure rises and solids content surges, placing extreme demands on primary solids control equipment. The LS585 linear motion shale shaker, developed by KOSUN, is a professional solution specifically designed for such high-difficulty conditions.

     


    High G-force Drive Enhances Solid-Liquid Separation Efficiency
    Complex formations often mean intricate cutting compositions, high viscosity, and large flow rates. The LS585 shale shaker is driven by dual vibration motors, with an adjustable G-force ranging from 6.5G to 7.5G. This high-intensity acceleration rapidly breaks the surface tension of the drilling fluid, allowing the liquid phase to pass through the screen quickly, achieving the triple goals of high displacement, low fluid loss, and high cuttings dryness. The shaker basket structure, optimized through Finite Element Analysis (FEA), ensures outstanding structural reliability under long-term, high G-force vibration environments.


    Five-Screen Configuration Increases Effective Processing Capacity
    To address the challenge of shaker screen overflow in high-solids conditions, the LS585 features a total net shaker screen area of 3.4 m². A single unit can be equipped with five API 40–200 mesh frame shaker screens simultaneously. This multi-shaker screen design significantly increases the effective filtration area, enabling it to easily process high-pressure, high-solids drilling fluid encountered in onshore/offshore deep wells and shale gas horizontal wells. Furthermore, the equipment is widely applicable to various systems, including oil-based, water-based, and synthetic-based fluids, demonstrating exceptional system adaptability.

     


    Detailed Engineering Design Optimizes On-site Operational Environment
    The LS585 shale shaker considers practical field requirements in every detail. The mechanical ratchet mechanism combined with a rapid tensioning system makes screen replacement convenient and efficient, effectively reducing maintenance downtime. Motor connection bolts utilize professional anti-loosening technology, completely eliminating risks of detachment in high-vibration environments. Additionally, the comprehensive anti-splash design minimizes mud loss, which not only reduces costs but also keeps the operational site tidy and clean.


    Beyond oil drilling, the LS585 shale shaker is equally suitable for geothermal wells, trenchless HDD, and mining applications. With the LS585 shale shaker as its core, KOSUN provides global customers with an efficient, reliable, and easy-to-maintain primary solids control guarantee, helping drilling projects advance steadily through the challenges of complex formations.

  • Analysis of Volumetric Conveying Principle of Screw Pump

    The screw pump occupies a significant position in the field of modern industrial fluid transportation as a high efficiency rotary positive displacement pump. Its core operating mechanism is established on the high precision meshing between the rotor and the stator, achieving fluid delivery by generating continuous volumetric changes between the suction and discharge chambers. As a forced displacement pumping system, this equipment can handle high viscosity and high solid content working conditions that are challenging for traditional centrifugal pumps, providing stable and reliable power support for industrial production.

    Structural Characteristics of SWP Series Screw Pump

     

    Based on general screw pump technology, the SWP series screw pump has enhanced operational performance through optimized design. The rotor of this series is manufactured from high strength stainless steel, while the stator is made of high performance elastomeric material. This combination grants the equipment unique advantages in handling media containing hard suspended particles. The spiral seal line formed by the meshing of the stator and rotor completely separates the suction and discharge chambers, providing the pump with an automatic valve like sealing function and enabling efficient multiphase mixture conveying of liquids, gases, and solids.


    Volumetric Conveying Mechanism and Hydrodynamic Performance
    The conveying process of the SWP series exhibits exceptional hydrodynamic stability. The liquid is pushed uniformly along the axial direction within the pump body, maintaining a low internal flow velocity and constant chamber volume. This motion ensures extremely high stability in output pressure and fundamentally eliminates vortex and agitation phenomena during transportation. For shear sensitive media, this gentle conveying characteristic effectively protects the physical properties of the material, ensuring consistent quality throughout the process.


    Integrated Solutions for Operation Control and Maintenance
    Regarding performance regulation, the flow rate of the SWP series screw pump is strictly proportional to its rotational speed. Combined with a reducer, it achieves precise stepless speed regulation to meet the stringent displacement requirements of various industrial processes. Furthermore, the equipment prioritizes maintenance convenience during the design phase. The specialized pump body structure significantly simplifies the replacement process for core wearing parts such as the rotor and stator. This integrated design not only reduces the total life cycle cost but also provides solid hardware assurance for high intensity operations such as drilling fluid processing and slurry transportation.

  • Composition and Operating Principle of MD Series Mud Cleaners

    In oil drilling, geological exploration, and horizontal directional drilling (HDD) projects, the performance of drilling fluid directly determines operational safety and efficiency. As the core secondary and tertiary solids control equipment in drilling fluid purification systems, the KOSUN MD series high-efficiency mud cleaner performs the critical function of precisely separating fine solid particles, providing a vital technical guarantee for the recovery and recycling of mud properties.


     

    The structural design of the MD series mud cleaner embodies a high degree of integration and durability. The equipment primarily consists of a customized hydrocyclone cluster, an underflow vibrating screen, high-performance vibration motors, and a supporting frame. As the core separation components, the number and material of the hydrocyclones can be configured based on actual flow rates and formation abrasiveness, typically utilizing high wear-resistant materials such as polyurethane, high-chromium cast iron, or ceramics to extend service life. The desilter hydrocyclones utilize bolt-clamp connections and are equipped with stainless steel ball valves, greatly simplifying routine maintenance procedures. The power system employs reliable Martin vibration motors paired with long-life composite screens, ensuring continuous and stable operation under complex working conditions. Furthermore, the equipment is equipped with an advanced wedge block design and a mechanical angle adjustment mechanism, allowing operators to quickly replace screens and adjust the screen box angle in real-time without interrupting operations to adapt to mud processing requirements of varying viscosities.

     
     

    Regarding the operating principle, the MD series cleaner follows a composite purification logic combining centrifugal sedimentation and mechanical filtration. After the drilling mud is pumped into the hydrocyclone cluster, fine solid particles within the 5–74μm range are classified by density and particle size under the centrifugal force generated by high-speed rotation. The separated concentrated underflow drops onto the surface of the underlying vibrating screen for secondary dehydration through high-frequency vibration. During this process, clean liquid passes through the screen and returns to the circulation system, while dry drill cuttings are discharged from the system. This design not only allows the equipment to operate efficiently as an independent purification unit but also enables the underflow vibrating screen to serve as a parallel backup for the primary shale shaker when necessary, significantly enhancing the redundancy and processing flexibility of the entire solids control system.
     
    From the perspective of application value, the MD series mud cleaner achieves a solid removal rate of over 90% thanks to its compact structure and powerful processing capacity. By precisely controlling the density and viscosity of the mud, the equipment effectively reduces the load on downstream fourth-stage separation equipment and lowers the cost of additional chemical additives. Meanwhile, because harmful solids are promptly removed, mechanical wear on drilling pumps and downhole tools within the circulation system is substantially mitigated, thereby extending the service life of core equipment. Whether in large-scale oil and gas drilling or specialized coalbed methane development, the MD series has become an indispensable efficiency tool in modern green drilling processes due to its excellent operational adaptability and maintenance economy.

  • KOSUN Environmental: Breathing New Life into Urban Waterways

    In modern urban ecosystems, the health of the water environment directly impacts the quality of life. However, long-term sediment accumulation often becomes an endogenous threat to water purity. To overcome the environmental challenges of dredging, technology is shifting from a simple "haul-away mode" to a sophisticated "factory-style treatment mode." Among these advancements, the integrated eco-friendly silt treatment equipment developed by KOSUN showcases the latest achievements in green dredging technology. 

    The Technical Logic of Eco-Friendly Dredging
    Traditional dredging is often accompanied by open-air sludge stacking and leachate leakage. The core of KOSUN’s river silt treatment process lies in "Reduction, Harmlessness, and Resource Utilization." Through steps such as pre-treatment, washing/screening, dewatering/volume reduction, and sediment stabilization, the process achieves a precise transformation from raw silt into clean backfill material.

    Synergetic Operation of Core Modules
    A complete silt treatment system consists of eight specialized functional modules. Within a closed-loop system, the material undergoes multi-stage screening and sedimentation. Notably, this process achieves highly efficient substance separation: sand and gravel are processed into clean sand for backfilling to restore the natural structure of the riverbed; meanwhile, the mud phase is solidified and reduced in volume through mechanical, physical, and chemical means within the dewatering unit, significantly lowering the costs of subsequent transport and disposal.

    Value in Diverse Application Scenarios
    The application of this technology spans critical scenarios, from urban river channels to the protection of drinking water sources. The system possesses differentiated treatment capabilities for silt with varying pollution levels, ensuring that both tailwater discharge and sludge cake disposal comply with environmental regulations. Through this closed-loop process, silt that once hindered aquatic ecosystems is converted into usable resources, supporting the remediation of scenic lakes and reservoirs while ensuring the long-term healthy development of the water environment.
