  • 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

  • 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.
