The reason for excessive shale shaker vibrating force and troubleshooting method

Tianrui shale shaker applied the imported Ouli vibrating  motor,with eccentric block at both ends, each shale shaker motor eccentric block contains one fixed eccentric block and one adjustable eccentric block. By changing the position of the adjustable eccentric block, you can adjust the vibrating force of the shale shaker.

Generally if the shale shaker has an excessive vibrating force, there are several reasons:

1.The shale shaker equipped with unsuitable vibrating motor. The shale shaker motor power is too large. The angle of the eccentric block should be adjusted at both ends to decrease the vibrating force of the shale shaker.

2.The shale shaker installation foundation is uneven, or fixed unsteadily. Should be re-installed the shale shaker to keep it fixed and stable.
 3, The shale shaker motor rotor is not balanced, so that the eccentric block is not on the rotor center axis. The balance should be corrected.
4, The shaft is bending. The shaft should be replaced.
5, Cage rotor bar broken, or winding rotor circuit breaking, so that the load current change all the time. Should check for repair the rotor.
6, Motor stator has a local fault,leading the rotating magnetic field imbalance, Should check and repair the stator.

Bore Pile & Mud Desander

Why and what is piling?

The ground will bear a lot of pressure because of the building on it.We must ensure that the ground has enough ability to bear the pressure.So it needs to strengthen the ground or improve the ground structure, that is the foundation Piling. Most of the weight of the building can be transformed to the ground through the pile down to deep position under earth.

Bore Pile Project

What are the characteristics of piling mud?

Piling mud is a kind of suspended liquid containing a certain amount of fine mud particles .It has a certain viscosity,so it is difficult to stratify for a long time.

What are the piling mud treatment methods?

1. Sedimentation pool method:  Building sedimentation pool on the construction site.Discharging sewage into the sedimentation pool, removing suspended solids, oil substances and neutralization treatment.Discharging to the river after reaching the environment standard.

2. Natural dehydration method: After dehydration and solidification naturally, the mud will transport to the spoil storage yard.3. Flocculation treatment: Adding flocculant in the mud water, destroying the stability of the muddy water, so that the mud particles will agglomerate and settle, so as to achieve the effect of mud separation.4. Equipment handling method: This method is to use some special piling mud treatment equipment to treat the piling mud, such as TR series of desander, desilter, shake shaker, centrifuge and so on. The biggest advantage of this method is to save effort and manpower, high efficiency of mud processing, more environmentally friendly. It is currently the popular processing options in pile construction.

Tianrui Shale Shaker Structure

Tianrui drilling shale shaker is mainly composed of shaker box,shaker screen,vibrator, buffer box, deck adjustment device, collector box and base.

The screen box not only bear the weight of the material being sieved, but also bear a great exciting force. Therefore, the structure of the screen box must be strong, not only have enough strength, but also have enough overall stiffness, so that the screen box would not damaged because of deformation.

There are many factors that affect the processing capacity of the vibrating screen. Among them are the rheology of drilling fluid, the type of cuttings, the mesh size, the screen area, and the deck angle of the screen.Tianrui Solid Control will make a reasonable design considering all of these factors.

The vibrating system is the core of the shale shaker, which plays a decisive role in the working efficiency, service life and application area of the shaker. According to the power source they can be divided into: electric, hydraulic and pneumatic.Nowadays the most widely used is the electric vibrator. Tianrui Solid Control is now applying the electric inertia vibrator.

The role of the buffer box is to avoid direct impact of the mud screen, while the slurry flow to the surface more balanced, improve the efficiency and screen life.

Deck adjustment device mainly plays the role of adjusting the angle of the screen box, which can affect the cuttings discharge speed and the processing capacity of the screen and balance the relationship between the two.

The function of the collector box is to allow the separated mud to flow into the mud tank.

The base would bear the whole weight of the vibrating screen and vibration load.The base needs to be designed with sufficient strength and stiffness,also it will ensure the stability of the control box through the role of shock absorber spring.

Tianrui solid control is a professional company engaged in the production and research of vibrating screen, can provide a series of high-quality, professional and customized services. Tianrui's products are widely used in oil drilling, urban tunnel boring system,bored pile, horizontal directional drilling and trenchless systems. Tianrui solid control is your one-stop mud processing equipment provider.

The reason for mud loss over shakers,mud shaker,mud recovery shaker

    There will have a variety of different problems in the use of the shale shaker, one of which is mud loss over shaker.We can find the reasons through continuous analysis and summary.They are mainly focused on high solid content in drilling fluid, high viscosity mud, scattered cuttings and other related factors; or on the small vibration force, the inappropriate screen mesh, the small screen area; also on the direction/position of the screen inlet.We can analyze these factors as follows:

Formation of the drilling layer and mud contents affect the amount of treatment. In another case, when drilled into a loose sandstone layer or flow sand layer, the sand is easy to stuck in the screen hole, causing screen-blocking phenomenon. So it needs to test several different mesh screen to reduce this phenomenon.

The screen mesh is unreasonable. Due to the rapid drilling of the surface layer, resulting in a large number of solid phase occupied the effective screen area. So the fine screen can not be used in shallow wells. Therefore it’s reasonable to use larger hole screen in the initial drilling process, and with the increase in drilling depth, then use finer screen gradually.

Check and make sure the turning-direction of the motor is correct. First remove the vibrator protection shield and check whether the eccentric block rotation of both motors rotated toward the outside. Second, if it is not correct, please exchange any two phase line in the electric control box. There may be two incorrect cases:1.The two motors rotate inward. Although the exclusion of cuttings out, but the speed is slow; 2. The two motor rotation in the same direction. The vibration force is very small, it does not exclude the sand nor recover the mud. 

Check the amplitude of the vibrating screen. The greater the vibration amplitude large processing capacity.So we can adjust the vibration amplitude greater if mud loss over shaker occurs.  

Check whether the fluid distribution in the screen frame is reasonable. We can control the fluid distribution through adjusting the front spring seat and so on.
