Acooring to 15 days production. DC Solid control finished an order of 25 sets JBQ15 Drilling Mud Agitator For Pakistan users. This morning, the mud agitators were delivering to port.

To keep both the mud uniformity and the suspension of solids, the mud agitator is used to agitate the mud consecutively and reliably.This agitator agitates the mud to make cuttings, silt and sand pass the solids control system without being precipitated onto the tank bottom.


Due to the simplex turbine decelerator, this product is featured by compact construction, light weight, balanced transmission, low noise, high efficiency of transmission and strong agitating power. Therefore, it is a reliable product in the solids control sys

JBQ series mud Agitator, Less than 5.5 kW drilling mud Agitator adopts the blender cycloid speed reducer, and it is applied to the drug liquids mixing tank. This mud agitator has the advantage of compact structure so it occupies small area.

More than 7.5 kW Mud Agitator uses the turbo and worm gear speed reducer, with the large torque transmission、 the revolution is steady、it works reliablely and has great merit. Common model of mud agitator is JBQ5.5kW 、JBQ7.5kW 、JBQ11kW and JBQ15kW.The drilling mud agitator is an important components for DC Solids Control drilling fluids processing system.

Mechanical agitators are used extensively for drilling fluid surface tanks. Regardless of manufacturer, mechanical agitators have similar components, namely, a drive motor, a geared reducer( aslo called a gear-box), a gear box output shaft, and impellers. The objective of a properly designed mechanical agitation system is uniform suspension of all solids, appropriate application of shear, homogeneous fluid properties through out the system and economical application of applied power.

Most mechanical agitators are driven by electric motors. These motors must be rated for explosion-proof duty( to ensure that motor, starters and wiring meet specifications for local codes and operating criteria) and may be mounted horizontally or vertically .

Motors may be coupled to or direct-face mounted to a gear reducer that in turn drives the impeller shaft. Impellers are mounted on the shaft at a specified distance off the tank bottom to achieve desired results.

The agitator main part is impeller. Impellers convert mechanical power into fluid movement, much like the impeller of a centrifugal pump. Considerable study has been devoted to proper impeller design and placement. Even impeller transmits power to the fluid in two ways:

1. Pumping ability
2. Shearing ability

Impeller design will promote one of these components by sacrificing effectiveness of the other. The amount of fluid that is moved by an impeller is its pumping capacity, or displacement capacity, and most manufactures have undergone extensive testing to determine flow characteristics and capacities for type and size of impeller.

The agitating shaft of mud agitator is the transmission structure can be rised. Agitator inadmissibility stopped in drilling process. It can’t get to the requirements in the practical work. After running of agitator, because sinking sand in the tank, maybe impellers buried in the sand, and it is difficult to start again. The impellers are often burned and appears motors burned. In order to solve the problem, usually oilfield adopts the agitator shaft which is can be rised, the impellers can be rised to a certain height. The impellers dive to the common location When re-start Agitator.


Agitator shaft of Mud agitator is divided into solid shaft and hollow shaft, the carbon steel shaft is the most commonly used. Solid shaft is directly on the reducer output shaft, usually adopts the rigid joint. There is a processed keyway on the bottom which can adjust the impellers installation height. It required inatall the stable end tube when the depth of container is exceed 1.83cm.

Hallow steel shaft apply to the deeper tank especially, they can connected with flange or bolt. Most hollow shaft all use bolt impellers which are joint to the scheduled location. Known from Mechanics of materials, in the same sectional area, hollow shaft more resistance to bend.

The rised agitating shaft is made of the hollow shaft of transmission torque and the screw shaft. The shaft installed agitating impellers connected the rised shaft through the coupling. The transmit torque can use the square hole, also can use the slide spline.
