The reason for the excessive damage of the screen is mainly the accumulation of clay, the wrong steering of the motor, the tightness of the screen and the screen frame, and the poor quality of the screen.
1. The vibration amplitude of clay accumulation is too small, it is difficult to screen under the condition of polymer drilling fluid, which can not effectively overcome the viscous force of drill cuttings, resulting in the accumulation of cuttings on the screen and rapid damage to the screen.
Solution: 1 increase the vibration amplitude; 2 use the sprayed water to sift the screen and cuttings to reduce the viscosity of the cuttings, but this method is only suitable for the occasion of adding water; 3 adjust the angle of the screen Next, it is good for the cuttings to be discharged by gravity, but it may lead to running the slurry; 4Replace the mesh of the screen or adjust the flow of the single screen to ensure that the flow stop of the drilling fluid is close to the outlet of the screen, so that the cuttings are lubricated in the drilling fluid. Smooth discharge under the action.
2. The motor rotates erroneously toward the inside. The throwing angle is also 45° forward, but the cuttings have a force to rotate backwards. At this time, the cuttings move forward much more slowly, staying on the screen for a long time, even This can cause the cuttings to fail to drain.
Solution: 1 When the sieve box is running, press the stop button of the electric control box. At this time, the vibrating screen will slowly stop, observe the elliptical path formed by the small point on the side plate during the operation of the vibrating screen, and turn to the sand outlet. Correct steering; 2Remove the vibrator cover, check whether the apricot eccentric block rotates to the outside; 3Replace any 2 phase lines in the incoming power supply of the electric control box, sprinkle some sand on the screen surface, and the sand discharge speed is faster. One is the right direction.
3. The screen and the screen frame are not tightly attached. After the strip supporting the screen is worn, the screen cannot be reliably contacted; the screen is not tightly tightened.
4. The quality of the screen is poor. The screen generally has an upper sieve layer and a lower force layer, and the two layers are required to be closely adhered to each other. If the screen pre-tensioning process is poor, when the force layer at the bottom of the screen is tight, the sieve layer is layered. Without tightening, the throwing force of the cuttings is greatly reduced during work, and the cuttings cannot be discharged.
