The uses of oilfield drilling fluid shaker

　　 Oilfield drilling fluid shaker During operation, the two motors rotate in synchrony in opposite directions, generating opposing excitation forces that drive the screen frame to perform longitudinal motion. This causes the material on the screen to be periodically thrown forward by the excitation force, thereby completing the screening process. The equipment is suitable for screening sand and gravel at quarries and can also be used for product classification in coal preparation, mineral processing, building materials, power generation, chemical engineering, and other industries.

　　The working part of the Drilling fluid shaker in oilfields is fixed, and the material slides along the working surface for screening. The fixed screen is widely used in mineral processing machines and is generally employed for pre-screening before coarse or medium crushing. It has a simple structure and is easy to manufacture. It does not consume electricity, and the ore can be directly discharged onto the screen surface. Its main drawbacks are low productivity and low screening efficiency, typically only 50–60%.

　　 Oilfield drilling fluid shaker Characteristics of the job

　　①. The excitation force is generated by block eccentricity, resulting in a strong excitation force.

　　②. The screening beam and screening box are fabricated using high-strength bolts, featuring a simple structure and convenient, quick maintenance;

　　③ A tire coupling is used, providing flexible connection and smooth operation;

　　④. The machine features a small-amplitude, high-frequency, large-inclination design, resulting in high screening efficiency, large processing capacity, long service life, low power consumption, and low noise levels.

　　Before starting the machine, verify that the supplied safety guard has been removed. Inspect all locking components to ensure they are securely fastened. Confirm that the screen mesh on the screening deck is tightly compressed. Check the connection between the rubber pads and the screen frame and side frames. Examine the attachment of the vibration motor to the screen body. Perform a visual inspection of the vibration motor. Measure the supply voltage. Verify the interlock control system for the vibration motor. Remove the motor end cover and check that the relative phase angles of the sector blocks are consistent; tighten the securing screws on the sector blocks. Ensure that the installation angles of the two motors are identical. Inspect the hose connections at the feed and discharge ports to confirm they are properly sealed—do not overtighten, as this could cause kinking when the screen body moves. During no-load trial operation, ensure there is no collision or abnormal noise between the screen body and the side frames. Measure the amplitude; the screen body should exhibit no deformation or other abnormalities during its reciprocating linear motion. After 10–15 minutes of operation, use a wrench to tighten the bolts on the drive mechanism.

　　 Oilfield drilling fluid shaker There are three material options: all-stainless steel, all-carbon steel, and stainless steel screen mesh with a carbon steel base. Stainless steel is hygienic and durable but relatively expensive; carbon steel is less robust. Oilfield drilling fluid shakers can perform simultaneous or multi-layer screening with 1 to 6 layers, resulting in clearer material grading. Screen replacement is quick and easy. In the screening of granular materials, screen damage is inevitable, so rapid screen replacement is an effective way to improve efficiency. Of course, you can also opt for oilfield drilling fluid shakers with more durable screens, which reduce subsequent maintenance costs. They are compact and lightweight, easy to move, and their materials extend service life. The operating principle is that the vibration motor provides sufficient power to drive the shaker, causing it to vibrate. Material smaller than the screen openings falls to the lower layer under the vibration, thus achieving stratification.
