The formation and mud conditions affect the processing capacity. As the drugs added in the drilling fluid are not fully dissolved and paste on the screen, serious slurry running will occur at this time. It should be used after the drug is fully dissolved, or a screen with larger holes should be used. On the other hand, when drilling into the loose sand-bearing rock layer or sand layer, sand particles are easy to get stuck in the screen holes, resulting in screen blocking phenomenon.

Therefore, several different mesh screens should be tested to reduce screen blocking.

Incorrect steering of vibrating motor of vibrating screen

First remove the vibrator shield and check whether the eccentric blocks of the two motors rotate to the outside. Secondly, if the steering is wrong, please replace any two phase lines in the incoming power supply of the electric control box. Error mode 1 (two motors rotate to the inside), although it can also remove drill cuttings outward, but the speed is slow; Error mode 2 (two motors rotate in the same direction), the vibration force is very small, basically no sand discharge or mud treatment.
Unreasonable amplitude of drilling fluid shaker

The larger the vibration amplitude, the larger the general processing capacity is relatively larger; the vibration force is adjusted to 90% when leaving the factory. In case of slurry running, the angles of the inner and outer eccentric blocks can be aligned.
