Mud Agitator is used in surface mud systems to suspend solids and maintain homogeneous mixture throughout the system. A mechanical agitator is driven by an explosion-proof motor, coupled to a gear box that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation. The objective is to obtain a uniform suspension of all solids.

Mud agitator

Principle of mud agitators

Agitators play an important role in the surface treatment of drilling fluid. Impeller type mixers provide both axial and radial flow, which lowers mud costs and improves mud properties. Impeller-type mixers are basically low-shear and low energy, inexpensive to operate and easy to maintain. Low- shear mixers are used to suspend and mix mud additives minimizing particles size degradation and polymer shear.

Mud agitators serve three purposes:

1.Ensure mud additives are homogeneously mixed, preventing spot over treatment of chemicals, dilution water or weighting agents.
2.Prevents the pits from” gelling” by keeping the active mud system moving when the mud pumps are disengaged.
3.When drilling with weighted mud, properly sized agitators will keep the weighting agents in suspension, minimizing solids from settling in corners or dead spots of the pit.

The auxiliary equipments for solids control system

Except to the shale shaker, desander, desilter, centrifuge and other mud cleaning equipments, the solids control system also including some auxiliary equipments.

1 Drilling mud agitator

Drilling mud agitator is used to stir and mix drilling fluid, prevent the drilling fluid solid particle deposit in the bottom of the cycle tank, and make the drilling fluid performance stable, mixture uniform.

2 Drilling mud gun

The function of drilling mud gun is depend on the nozzle produce the high speed liquid flow, impact the sedimentary solid phase in the bottom of mud tank so that it is suspended. At the same time, after a period of time of stopping the mud agitator, because of the sedimentary solid phase bury the impeller, so the mud agitator needed to restart, the mud gun can eliminate a part of resisting moment which produced by starting the agitator.

3 Hopper

In order to weight for the drilling fluid in drilling process or configurate a little drilling fluid, we generally install the weighted hopper near the suction tank, the discharge pipeline should reach to the hold-up tank and suction tank, so that deal with down hole accident timely.

4 Pipeline

When drilling middle-deep well, in order to deal with down hole accident timely, the arrangement of pipeline should make the drilling mud pump can pump the drilling fluid in hold tank quickly, the drilling fluid discharged from the hopper can be transported into the mud tank, and all of these depend on the pipeline and valve to control.

 

Drilling mud agitator mixer shaft

All parts which make the rotary motion, such as gear, mixer, etc, all of them must be installed in the shaft, for delivering motion and power. So shaft is one of the main parts of the machine.

Mixer shaft material

The choice of drilling mud agitator mixer shaft material, from stress and working conditions to make it safe, suitable, easy to manufacture and economic. The material of shaft should have enough strength, stiffness and toughness. In addition, in order to easy to manufacture, we also need to have excellent cutting processing skill, so that we usually use number 45 high-quality steel. For the low requirement mixer shaft, also can use Q235-A or number 35 steel.

 

Gland packing material

In the actual use, the most common dynamic seal have two kinds: packing seal and mechanical seal. Drilling mud agitator shaft belongs to low speed, low pressure, applicable is packing seal, the packing seal has the advantage of simple structure, easy to maintain and high reliability.

For adapt to requirement of agitator in different cases, the category of gland packing material are many. Which kind of material to choose mainly according to the mixer shaft spindle speed, operating temperature, operating pressure and chemical property of material.

In general, the material used to manufacture gland packing must meet the following requirements:

1 Should be resistant to the soaking and corrosion of medium and lubricant, and does not contain the material which can be swelled and weakened by medium and lubricant.

2 Should have enough flexibility, to absorb the design which can’t avoid shaft moving.

3 Under the situation of gland pressure is too tight, it still has running freely, will not produce destructive friction and heat performance.

4 Should have enough plasticity, under the packing gland compression can be adapt to the shape of shaft and seasoning function and for deformation.

5 Won’t bite or corrosion shaft.

6 Wear slow, rarely need to adjust and change.

Usually the materials used to make gland packing have fiber, metal and lubricant, etc. User can according to the specific work to choose.

 

 

Drilling mud agitator shaft seal

Drilling mud agitator reliable seal is an important thing. The oil leak caused by mud agitator seal, not only waste oil largely, but also pollute drilling fluid. Because of mixer shaft is the rotary motion, so its seal belong to dynamic seal.

The basic requirements to dynamic seal:

1 Seal should be reliable;

2 The structure of seal should be simple, easy to loading and unloading;

3 Seal service life should be long.

In the actual use, the most common dynamic seal have two kinds: packing seal and mechanical seal. Drilling mud agitator shaft belongs to low speed, low pressure, applicable is packing seal, the packing seal has the advantage of simple structure, easy to maintain and high reliability.

The following picture is the drilling mud agitator packing seal structure, it is composed of 1-bushing, 2-packing box, 3-O ring, 4-water leg, 5-packing ring, 6-gland, 7-holding down bolt, etc.

The principle of packing seal

About packing seal principle can do such description: the padding filled into  annular gap between mixer shaft and stuffing box, under the effect of gland force, produce radial compression force to the mixer shaft surface. Because of the packing contains lubricant, so there will produce a layer of thin liquid film when produce radial compression force to the mixer shaft surface. The layer of liquid film on the one hand make mixing shaft get lubrication, on the other hand avoid to leak liquid or exterior liquid permeate. This is the principle of the packing seal.

Although added some lubricant when manufacture padding, but the quantity is limited, because the lubricant still be consumed constantly, so only rely on the padding itself lubricant is not enough, so we should also add a lubricant device on the gland box, to meet the need of continuous lubrication.

Drilling mud agitator drive structure

Drilling mud agitator drive structure is mainly composed of motor, reducer, coupling and mixing shaft. The most common types of drilling mud agitator in solids control equipment is not much. Mainly for the following types.

Gear drive structure mud agitator: the advantage is higher transmission efficiency; shortcoming is larger volume, not easy to maintain. Gear drive can be divided into direct drive and belt drive.

Bevel gear drive structure mud agitator: has the advantage of simple structure, but also has many shortcomings. For example: due to drive ratio restriction, if you want to get slow-speed of revolution drilling mud agitator, must be through the pulley to do a larger reduction, the results not only low efficiency, but also large volume. This kind of structure is rare in drilling mud agitator.

At present most used mud agitator is still worm and gear drive. Worm and gear direct drive has the advantage of simple structure, large gear ratio, high reliability, widely used in mud cleaning system.
