Adjustment and Maintenance for Shale Shaker in Drilling Fluid System

Shale shakers are considered by most of the drilling industry to be the most important device in the solid control system as the performance of the successive equipment directly relates to the cleanliness of the treated drilling fluid.

AWD angle adjustment system
The angle adjustment system while drilling, AWD for short, can raise or lower the screen basket end during the work. This part includes two vertical column assemblies that are connected on the upper column assembly and are attached to the shaker base.

The movable part of AWD consists of the lower column,limit device that controls vertical movement and hydro jack that drives the upward & downward movement of the screen basket. The fixed ends of jack are connected in upper column assemblies and the movable piston bar is fixed in the lower column assembly. Reciprocately pulling the operating grip of the hand pump or starting the oil return valve of the hand pump can make the screen basket move upward and downward respectively. The shaker screen basket can be adjusted within -1°～+5°. Fix and lock the elevator with clamp pin at the suitable angle, which can reduce the attack on the hydraulic pump when the basket is running at this angle.

Maintenance Plane
As usual, due to metal "hard in hard" cooperate relationship easy to lead to the shale shaker wear and tear on parts when it in the process of running, for example, the shale shaker main shaft bearing wear and failure. After go wrong the above problems, the traditional enterprise solution is machined after repair welding or brush plating to repair, but both of the ways have some disadvantages: repair welding of high temperature thermal stress can not completely eliminate, neither repair welding thermal stress effect, repair the thickness is not restricted, and at the same time the product of metal materials do not have rolled back, and it also can absorb the impact of shaker equipment, avoid the possibility of wear and tear, and greatly prolong the service life of equipment components, save a lot of downtime for the enterprises, creating huge economic value.
