The shale shaker is often used as drilling equipment,shale shaker is very important as the main device in drilling fluid solids control system.The linear motion shale shaker manufactured by KOSUN has obvious advantages when dealing with large displacement drilling fluid.
Linear motion shale shaker output strong exciting force, can rapidly remove a large number of solid phase through efficient linear vibration locus, can effectively remove the larger particles in drilling fluid. As the first stage of purification of the drilling fluid, shale shaker is the role of removing the larger particles larger than 70μm in the drilling fluid from the well head back out are and no broken to the next level of mud solids control equipment for drilling further purification.
Shale shaker performance will directly affect the treatment quality of the first stage, in addition, also have a great impact on the play of next purification device performance.
Currently,the shale shaker used in drilling have the same structure and working principle , the high-speed rotation of the eccentric shaft driven by the motor, generating a strong centrifugal force when the rotation of the eccentric shaft to the elastic transducer, secured to the frame of stainless steel mesh cloth with high the frequency of the vibration, the larger drilling cuttings are removed by screen. Now let's analysis the maintenance and the reasons of common fault of KOSUN drilling mud shale shaker.
Methods for Drilling Shale Shaker Maintenance:
1, When using the shale shaker,it is better to use the multiple shale shaker, so that not only can improve the bearing life, and other screens for extending the life of components is also very effective.
2, In the course, if we find there is the phenomenon of mud paste network, be sure to wash in a timely manner, to avoid long-term do not clean up, resulting in harm reduction shaker life.
3, During use, every 24 hours it need to add dropwise to the butter machine. Regularly check the screen box side bolts, if loose, timely tightening.
4, When stoping the shale shaker, you should rinse with water screens and clean drilling fluids and sand embedded in the hole of screen with a hair brush.
5, The belt tensioning should be moderate, it's better to not to slip and does not produce severe beating. When shutdown, you should always check the tightness of the belt and timely adjustment.
6, The pulleys and vibration motor shaft are cast iron parts, which are connected by shaft sleeve and keys. When handling avoid banging, to prevent crushing. To this end, the sleeve has a top end surface of the wire 3-M12 and fastening bolts 3-M8, it's easy accessibility, easy replacement.
7. When lifting, non-foot and shaker screen during transport,it is prohibited save anything on it. The shale shaker screen box must be bolted with a fixed base four bolt of M20 × 110 before lifting and transport, to prevent shale shaker box excessive vibration and jumped off.
The shale shaker has stopped running when running in hole, and because drilling fluid is no longer circulating, the viscosity of up to more than 100μ, it's time to open the flapper of the shale shaker slots where drilling fluid through into screen,and close the flapper of the shale shaker where drilling fluid through, to prevent the drilling fluid of high viscosity flowing to the screen surface and paste mesh. If the flapper not closed tightly, there are drilling fluid into the screen,you should rinse shale shaker screens with water timely .
