Category Archives: Mud Agitator

The mud agitator is widely used in the ground tank of the drilling fluid. The mechanical mud agitator is made of the drive motor, gear reducer, transmission box output shaft and impeller ect.The appropriate mud agitator can keep all the solid phase particles uniform, if  the shearing action is proper, the performance of the drilling fluid system is all the same and can save power.

  

The principle of operation

The impeller can stengthen the stirring effect by making vortex of the drilling fluid. The tray installed between the leaf blades can prevent the deposition of the solid particles when the machine stopped, thereby, to reduce the moment of resistance inflicted by the sediment to the impellers when restart the equipment, therefore, to avoid burnout of the machine.

The structure of the mud agitator

The transmission mechanism

The transmission mechanism are mainly made of motor, reducer device, coupling and the mixer shaft, there are a few drilling fluid mud agitators in the solid control equipment. The rotating mechanism of the turbine and the worm is simple, the strong reliability, it is the most popular in the drilling fluid, now the foreign all use the worm and gear to rotate directly.

Impellers

The impeller is the part of rotation, the structure of the impeller determines the function of the impeller, the sharps of the different liquid storage tanks are different, we select the different impellers according to the experiences and customs. The reasonable method is according to the mixing purpose and the formation of flow state to select .

The mixer shaft

The mixer shaft is the structure of lifting, in the process of the drilling fluid, the agitator can’t stop. There are some causes in the practical work, so usually it can’t reach the
Requirement. After the agitator stoped, because the tank has desilting, the serous tables are buried in the desilting, it is very difficult to start. The blades are often breaked and the motor is often burning loss.

DC Solids Control as a professional manufacturer for soilds control equipments, we have designed lots of high-quality products, and JBQ series Agitator is one of them. 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 system.

 

Drilling fluid gun belongs to the water conservancy agitator equipment, its function is rely on high speed fluid which is produced from the gun nozzle, impacting the solid phase which in drilling fluid bottom storage tank and keep it suspension. After the agitator stop a period of time, the depositional solid phase bury the impellers, it is needed to restart, drilling fluid gun can eliminate a part of resistance distance when the agitator start, it can provide the reasonable guarantee for regular work of agiatator.

The mud agitator is composed by explosion-proof electric machine, reducer,engine base and impeller components. The electric machine ,reducer and impeller shaft are connected with each other by solid couplings. 4 leaf blades were welded on each impeller.

Operarting Principles: The impeller can stengthen the stirring effect by making vortex of the drilling fluid. The tray installed between the leaf blades can prevent the deposition of the solid particles when the machine stopped, thereby, to reduce the moment of resistance inflicted by the sediment to the impellers when restart the equipment, therefore, to avoid burnout of the machine.

   

The structure of drilling fluid gun

According the structure of drilling fluid gun, it is divided into stationary type and rotation type.

1 The stationary type drilling fluid gun is similar with water conservancy agitator which the tank has nozzles, but the drilling fluid gun is installed on the two diagonal which is from 200meter to the bottom tank, the nozzle direction is parallel the longitudinal tank wall of circulation tank.

2 The rotation type drilling fluid gun is divided into hand regulation and autorotation. The hand regulation agitator has two hinges, it is made of access tubes, shell, spray gun and the replaceable nozzle

The differences

1 The cost of drilling fluid gun is lower than mechanical agitator.

2 In the premise of meet the requirements of pump power can use the drilling pumps.

3 The flow can concentrate in a location to decrease or eliminate the dead zone.

4 The weight is lighter than mechanical agitator.

5 It can improve the rate of shearing.

Shortcomings

1 If use along the drilling fluid system stir, it need a lot of drilling fluid guns, the cost of pumps and pipes is big.

3 The nozzle is abraded and let to high speed flow, it needs greater power, if the nozzle is not replaced in time, it may led to motor overload.

4 If solid phase have already precipitate, drilling fluid gun directly shot to the sediment, the sediment is maybe blocking the pump, conical shield or centrifugal.

The spray gun with the nozzles, rely on the two hinges, it can spurt any direction in the two perpendicular planes inside. The automatic rotary drilling fluid gun is made of input pipes, body gun, cross fitting, the two bends with nipples, replacement nozzle and two coat nots.

 The use of drilling fluid gun has a certain limitation, drilling fluid gun is auxiliary tool of mechanical mixing plant device, the mud gun can dispose the solid phase suspension which is didn’t disposed by mechanical agitator. According the research date, the depth of useful effect is only 1.5-2.7m, it is related with the drilling fluid density, viscosity and the speed nozzle.
