What is the structure and principle of an oilfield drilling fluid shaker?

　　Nowadays, many people still have... Oilfield drilling fluid shaker We are not familiar with some basic information about it, so as a manufacturer, it is necessary for us to give a brief introduction. In fact, this oilfield drilling fluid shaker is ubiquitous. It has a unique structure and plays a very important role in the industrial field. Therefore, we should promptly understand its principle and structure so that we can become more familiar with and use it more quickly during operation.

　　The oilfield drilling fluid shaker mainly consists of a base, a screen box, a screen mesh, a mud conditioning tank, excitation motors, vibration-isolating springs, control switches, and adjustment devices. Screen box: The screen box adopts soft (or hard) hook-edge screens, frame screens, or spiral tensioning and wedge-lock structures, which ensure safe and reliable tensioning and are less likely to damage the screen mesh. This design is highly reliable, easy to operate and maintain, and simple. Mud conditioning device: Drawing on well-known foreign brands, the design has been optimized for better structural performance, resulting in excellent mud damping and extended screen life. Power unit of the oilfield drilling fluid shaker: Composed of a vibration-isolating beam and two explosion-proof vibration motors from reputable brands, it features low vibration noise, stable operation, long service life, and convenient installation and maintenance. Vibration-isolating device: Made of high-strength composite rubber, it offers good stability, effective vibration isolation, and low noise. Adjustment device: The oilfield drilling fluid shaker uses a screw-adjustment mechanism, providing high adjustment accuracy, good stability, and simple, convenient operation. Control device: Equipped with either explosion-proof or non-explosion-proof branded control units, it boasts excellent safety and protection performance, reduces start-up stress, and enjoys a long service life.

　　The oilfield drilling fluid shaker is the primary solid-control equipment in the drilling mud solid-control system, responsible for managing mud solid particles larger than 74 μm at the well bottom. The drilling fluid shaker is based on a vibration motor and, under the action of an eccentric block force, Oilfield drilling fluid shaker By transmitting vibratory motion through a vibrating beam, linear, circular, or elliptical reciprocating motion paths are generated. The vertical axes of the two exciter motors are inclined at an angle relative to the screen, or aligned in a straight line, such that the two exciter motors rotate in opposite directions. In the X direction, the excitation forces produced by the two motors cancel each other out, resulting in zero net excitation force. In the Y direction, however, the excitation forces of the two motors add up, driving all the upper and lower screen boxes to reciprocate along the Y axis while simultaneously causing the slurry on the screen surface to move upward along the Y axis and then fall freely back down. As the slurry moves forward, it is continuously tossed up and down, which propels it ahead; meanwhile, the slurry liquid permeates through the screen mesh into the slurry collection trough, removing solid slurry particles larger than the mesh openings and thereby achieving slurry purification.
