With the improvement of motor technology and screen technology, the self-synchronous linear drilling fluid vibrating screen has been widely used in the late 1980s. It can use 200 mesh or finer screen. With the development and maturity of vibration motor technology, the power source is combined with the vibration source, that is, a set of adjustable eccentric blocks are installed at each end of the rotor shaft, and the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block is used to obtain the exciting force. . In addition, the vibration motor has a high utilization rate of excitation force, low energy consumption, low noise, long life, and the excitation force can be adjusted steplessly.
The self-synchronous linear drilling fluid vibrating screen overcomes most of the disadvantages of ordinary elliptical vibrating screens and circular vibrating screens, has better solid-phase particle transport performance and liquid-phase sieving ability, and uses fine mesh screens. When the traditional non-translational elliptical drilling fluid vibrating screen and circular drilling fluid vibrating screen work, the solid phase movement process of the screen surface has no directionality, and the solid phase movement direction is even at each point of the screen. At the same time, in order to achieve better solid-phase migration and drilling fluid processing capacity, the vibration system should be assembled at an angle to the same level. A throwing angle of 90 degrees with the screen can easily make the solid phase take off better. When the throwing angle is 0 degrees, the solid phase migration speed is fast. At this time, the liquid phase migration is insufficient, and the sand is discharged. The solid phase of the mouth contains more liquid. Therefore, most of the installation angles are about 45 degrees from the horizontal plane. The installation angle of the shaker of some drilling fluid shakers can also be designed to be adjustable. For small hours, such as from 30 degrees to 0 degrees horizontally, the component of the synthetic excitation force in the direction of the parallel screen will increase. The greater the force in the direction of the parallel screen, the faster the solid phase particles move along the screen; the greater the force in the direction of the vertical screen, the greater the amount of drilling fluid passing through the screen, and the residence time of the solid phase on the screen will increase. . Most manufacturers choose an installation angle of about 45 degrees with the plane of the screen, and the component force is roughly the same in both directions, because the drilling fluid shaker must have good liquid sieving performance and sieving solid phase movement at the same time. Performance.
At the beginning of the application of the linear drilling fluid vibrating screen, people once mistakenly thought that it was unnecessary to use other solid control equipment. However, the analysis of the particle size of the solid phase particles processed by the linear drilling fluid vibrating screen showed that the lower-level solid control equipment was still necessary. Few, the linear drilling fluid vibrating screen cannot currently replace other equipment in the entire solid control process.
