 Drilling fluid shaker


  The Drilling fluid shaker is equipment used in the drilling fluid purification system. The imported vibration motor is suitable for single, double, and triple purification of oil drilling fluids, while Drilling fluid shaker It can also be used for cleaning the underflow shaker. First, the shape and type. The drilling fluid shaker is a conventional device used to separate solid phases from circulating drilling fluid, and there are various shapes and types of shakers, such as when the drilling fluid flows through a square or rectangular screen. The drilling fluid flows along the center of a rotating non-vibrating cylindrical screen. The drilling fluid flows from the annular screen core to the screen periphery.

  Other shakers have been tested but not yet commercialized. Most shakers are located at the lower end of the rectangular screen, with a large vibration removal capacity and low drilling fluid consumption, allowing the drilling fluid to be recirculated through the shaker. Drilling fluids larger than 74 microns perform relatively poorly. On this basis, the API200 shaker was developed. Among the weighted materials that meet the API grading standards, only 3% are larger than 74 microns. At this size, most barite will be removed from the drilling fluid, seriously affecting its performance and drilling costs. The drilling fluid shaker mainly consists of a base, a screen box, a screening machine, a logging tank, a vibration motor, vibration-damping springs, control switches, adjustment devices, and other components. Screen box: The screen box features soft (or hard) hook screens, frame screens, bolt-tension or cheese-block structures, making it safe and reliable, less prone to damage to the screen mesh, with secure knotting, dependable operation, and simple operation and maintenance. Drawing on well-known foreign brands, the structural design has been optimized for excellent buffering performance, extending the service life of the screen mesh.

  Power: Composed of an impact beam and two brands of explosion-proof vibration motors, offering low vibration noise, stable performance, long service life, and easy installation and maintenance. Vibration Reduction: Features a high-strength composite rubber structure that provides excellent stability, superior vibration damping, and low noise levels. Adjustment: Equipped with a screw-adjustment mechanism that delivers high adjustment accuracy, good stability, and simple, convenient operation. Control: Available with either explosion-proof or non-explosion-proof control systems from reputable brands, ensuring robust safety performance, effective start-up protection, and extended service life.

  The Drilling fluid shaker is a solid-control device in the drilling-fluid solid-control system. It can process data from solids larger than 74 μm at the bottom of a well. Drilling fluid shaker Based on this vibration-control mechanism, the motors, under the action of the eccentric mass force, generate linear, circumferential, or elliptical translational motion trajectories as the excitation wave propagates. When two motors are arranged such that their vertical axes form an angle with the screening angle—or operate in a linearly coupled configuration—their rotational directions are opposite, causing their excitation forces to interfere with each other in the X direction and effectively cancel out, resulting in a net excitation force of zero in that axis. Meanwhile, the primary vibratory forces generated by the two motors in the Y direction mutually reinforce one another, driving the entire screen frame to oscillate up and down along the Y axis while simultaneously propelling the surface mesh upward in the Y direction. This creates a free-fall-like motion without any forward progression; thus, the material is thrown forward, passes through the screen openings into the collection hopper, and larger solids and particles are separated out by the mesh, thereby achieving purification.
