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.

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.

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 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.

Advantages

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.
