Shale shaker in the process of using running plasma problem causes and solution

KOSUN provides shale shaker in the process of using running plasma problem causes and solutions for your reference:

Analysis: this phenomenon, mainly with high content of solid phase drilling fluids, mud viscosity, dispersion cuttings were sieved material factors; shaker vibration force with small, high mesh sieve, screen the small size of their own conditions concerning; shaker and field installation of the inlet direction and location have a great relationship,

you can analyze the following step by step from several points:vibrating screen manufacturers

1, selected sieve size unreasonable. Each shaker processing capacity of 50L / s, it is because the processing capacity of the test conditions are based on national standards: selection screen of 60 mesh, increase in the proportion of 1.8 tested slurry, slurry viscosity of the slurry containing different particle size sand. As quickly got into the surface layer, resulting in a large number of solid-phase occupies an effective screen area and thus can not Asai segment shaker with a fine sieve. Thus, the initial drilling holes larger screen should be used, and as the drilling depth increases, the gradual introduction of fine mesh.crushing and screening plant

2, formation and mud conditions affect processing capacity. As the drilling fluid can not fully dissolved drug added, the paste in the sieve, run time of a serious phenomenon of slurry. And other drugs should be fully dissolved before use, or the use of larger mesh screen. Alternatively, when the drill rock or sand loose sand layer, the sand screen easily stuck in the hole, causing the blocking phenomenon sieve. Therefore, to test several different mesh sieve sieve to reduce the blocking phenomenon.

3, check the motor rotation is correct. First, remove the vibrator shield, check the two motors are both eccentric rotation outward rotation. Secondly, if the steering error, please exchange electronic control box into the line supply in any two phase lines. Wrong way one (two motor rotation toward the inside), although it can exclude outward cuttings, but slow; wrong way two (two co-rotating motors), vibration force is very small, basically does not handle row of sand slurry .

4, check the shaker amplitude. Vibration amplitude greater processing capacity is relatively more generally; factory vibration force adjusted to 90%. If running plasma condition can be aligned with the inner and outer eccentric angle, the vibration force is 100%. (Mud treatment time increased by only about 15%)

5, check the flow distribution in the sieve frame is reasonable. Crochet mesh structure of the shaker, lower than the middle on both sides of the screen surface, mud flows easily lost on both sides and run, should ensure that the mud from the middle into the shale shaker screen frame.

Workaround: You can use two scenarios:

First, adjust the front spring seat, the front of the screen box appropriately elevated angle;

Two is to adjust the position of extending slot flip board, control the flow distribution.
