mud agitator parts made in china

Derrick mud agitators include an explosion-proof, “C” faced motor, reduction gearbox (helical-bevel gears for horizontal agitators or all helical gears for vertical units), impeller, and shaft with assembly bushings. Motors range from 5 to 30 HP and may be supplied in several power configurations.

Attaching the motor directly to the gearbox protects correct alignment that can increase bearing life and provides 95 percent efficiency in power transfer to the impeller. Using this superior design surpasses standard worm drive gear assemblies by 30 percent, allowing Derrick agitators to do the same work at far less horsepower. By unitizing the motor and gearbox, weight and space requirements are reduced. Horsepower, mechanical configuration, impeller diameter, and shaft length are customized to tank dimensions and maximum mud weights. Available horsepower ratings* are: 5, 7.5, 10, 15, 20, 25, and 30.

Mud Tank Suction Valves & Dump Valves is the mud control equipment installed in the inside of mud tanks or water tanks. It is used to import mud or liquid phase and prevent different nature of mud or liquid in both side of mud tank to mix with each other.

KOSUN mud agitator is part of the drilling fluids solids control equipment, which is mainly used to agitate and mix the drilling mud to prevent solids particles from depositing in the circulating tank and to stabilize the performance of drilling fluids. The motor and speed reducer, speed reducer and impeller shaft are connected by steel coupling.

The mud agitator is generally installed on the surface of the mixing tank, and the mixing medium is mainly solid and liquid, including mud, muddy water, oil and water and other media. The mud agitator is mainly composed of motor, reducer, base, stirring rod, impeller and other spare parts. Among them, the motor and the reducer, and the reducer and the pulsator shaft are all connected by a rigid coupling, and the pulsator is assembled by welding four blades.

In the actual use of mud agitator, often due to the quality of the motor, reducer, base, stirring rod, impeller and other spare parts will fail or be damaged, so the quality of the spare parts of the mud agitator directly determines the effect and life of the agitator. When we choose a mud agitator, we need to know the daily maintenance and troubleshooting methods of the mixer’s spare parts.

The failures caused by the mud agitator spare parts include drive failure, transmission failure and mechanical failure. The failure of the explosion-proof motor parts of the mud agitator will cause the drive failure of the motor unable to rotate. The failure of the reducer spare parts will cause the motor torque to be unable to be transmitted to the stirring rod through the reducer, and transmission failure occurs. If the maintenance is improper, for example, the reducer is not often lubricated, it is indeed easy to malfunction; the impeller of the agitator, The material of the extension bar spare parts or improper installation may cause other mechanical failures. Therefore, the two important parts of the motor and reducer need to be specially maintained during the use of the agitator.

Brightway mud agitator adopts circular arc cylindrical worm reducer, the shaft section is circular, and the tooth profile of the worm gear is a circle conjugated to the worm. The meshing performance is reliable and durable. The various gearbox and blade combinations of the reducer can meet most requirements; the explosion-proof motor is of reliable quality and is suitable for use under harsh working conditions in the field. The whole agitator has the characteristics of high mixing intensity, reduced starting resistance torque, wide spreading range, long service life, and good mixing effect.

LJB Vertical mud agitator have almost same principle and superiority with JBQ mud agitator. But for LJB, the motor and gear box connection way is vertical. This type agitator request less space, it’s more convenient to process drilling mud.

The transmission structure of drilling mud agitator is mainly composed of driven motor, reducer gearbox, connecting device and mixing shaft assembly. There are not many forms of drilling fluid agitators commonly used in drilling fluids solid control systems. Among them, there are worm gear direct transmission and worm gear coupling transmission.

Mud agitator is used at trip tank, pill tank, desilter tank, mud suction tank, mud reserve tank, mud mixing tank. It is also used under the decanter centrifuge to avoid the mud settle down.

Mud agitators are normally used together with mud guns. Normally a mud agitator with a mud gun. The mud gun is used to support the 4 corners of mud tanks. GN Solids Control mud guns have 3 nozzles. Each nozzle]of GN mud gun can cover 120 degree, the 3 nozzles can cover totally 360 degree of the mud gun. The mud agitator is driven by electric motor. While the mud gun is driven by centrifugal pumps which are used for mixing or mud discharge.

Some manufacturers have also used worm gear and worm coupling drive. Worm gear drive is widely used indrilling fluid agitator due to its simple structure, large speed ratio and high reliability. Early drilling fluid agitators were almost all directly driven by worm gear. Although the worm gear coupling drive and belt drive are large in size, they have the characteristics of soft motion, which is good for protecting the overload of the motor. Therefore, some manufacturers will choose them.

The most commonly used agitator transmission mode is the gearbox reducer. The advantages of gear reducer agitator are high transmission efficiency and less maintenance. The disadvantage is large volume. Gear driven agitators are also divided into direct drive and coupling drive. The direct drive mud agitator is the most commonly used agitator drive form at present because of its simple structure and convenient maintenance.

Generally the mud agitator is a mechanical equipment used to agitate different materials widely used in engineering field. In the offshore plants, it is used to mix both drilling mud and bulk. Drilling muds are of high viscosity fluids that composed with oil or water and bulk. Therefore, it is necessary to predict and understand the stabilized mixing performance of agitator because the accurate material property maintained by agitation is essential to stabilize drilling system.

Drilling mud, which is the mixture of oil (or water) and bulk (Barite, Bentonite, Polymers etc.), is used to lubricate the drilling bit, to remove the cutting and to keep the pressure steady inside the drilling hole. Although there are many different types of facilities from which drilling operations take place, the core system of these facilities is drilling system, which is mainly composed of bulk-handling and mud-handling systems. The efficiencies of transportation, mixing in an mud agitator and separation of gas in a separator are important for the performance of these systems.

There are few of research papers for analyzing the flow field of mud agitator. Numerical simulations in regard to change torque and position of impellor with 45° pitched blades was performed by Chang and Hur. The flow patterns in agitator relating to its geometric shape and power of agitation was investigated by Kumaresan and Joshi which were made through experiments using LDV(Laser Doppler Velocimeter) and numerical method. And the performance of agitation with various size of impellor was studied by Nienow.

In this study, numerical simulation of swirling flow on a mechanical agitator is carried out to investigate the mixing performance of agitator using two commercial softwares, STAR CCM+ ver.8.04 [4] based on Eulerian approach and Particleworks ver.4.5 based on Lagrangian approach. First, for the validation, the water mixing problems by a mechanical agitator is simulated and the results of simulation are compared to those of experiments performed by Nagata et al. . Furthermore, the premixed drilling mud with a constant viscosity is considered as a mixing material, and the comparison of mixing performance with the case of water mixing is discussed.

To validate the present simulation with the experiments performed by Nagata et al. [6], the geometric shape of agitator is identical to the impellor which is one of the models used in the experiments as show in Fig. 1. The details of dimension are summarized in figure of dimention mud tanks. The impellor has 16 blades of flat plate. Impellor of agitator is rotating with 72rpm, and a linear acceleration time is adopted until 2sec.

Two commercial softwares, STAR-CCM+ and Particleworks, are used to simulate the rotatory flow around the mud agitator inside a cylindrical tank. The free-surface elevation and magnitude of velocity at specific location are validated with experimental results [6]. The location of probes for measuring magnitude of velocity is given in TABLE 3.

The magnitude of velocity probed at three locations in vertical is illustrated in Fig. 4. The peak values of velocity appear near the end of blades in the experiments, but slightly shifted inside in the simulations. The overall trends and agreements between the experiments and simulations are almost reasonable within 10% error band except for the case at prob3 for z=10cm. It means that the mixture by mud agitator cannot be well made upward in the simulations. The deviation from the experiments seems not to be related directly to the grid convergency, as shown in Fig. 5. The cases for the grid convergence test are classified in TABLE 4. Fig. 6 shows the time evolution of swirling motion due to the rotating of an mud agitator inner tank, in which the contours indicate the magnitude of velocity. As the time increases, the maximum distribution of velocity is generated in horizontal near the end of blades and developed in all directions. When the time becomes over 15sec, the quasi-steady swirling motion respect to the vertical centerline can be observed.

Next, the premixed mud which has the constant viscosity of 23CP and specific gravity of 1.3 is assumed to be fulfilled inside the tank instead of the water used in the previous study. Figs. 7~8 show the comparison of the wave height and the magnitude of velocity along the centerline with the case of the water mixing, respectively. Because the viscosity and density of mud are higher than those of water, the motion of freesurface is less dynamic in case of the mud mixing so that the change of free-surface and magnitude of velocity are relatively smaller. It causes that more time should be needed to reach the

In this study, numerical simulation of swirling flow on a mechanical mud agitator was carried out to investigate the mixing performance of agitator using both of Eulerian and Lagrangian approaches. First, the water mixing problems by a mechanical mud agitator was simulated and the results of simulation were validated with those of experiments by Nagata et al. [6]. The overall agreement was reasonable with the deviation within 10% error band. Furthermore, the premixed drilling mud with a constant viscosity was considered as a mixing material, and the comparison of mixing performance with the case of water mixing was discussed. It seems that the higher viscosity and heavier density of mud contribute to the resistance of mud mixing, compared to water mixing.
