Three key points to choose mud agitator

Mud agitator is a special mixer, under normal circumstances can not be simply will be used in chemical industry, oil refining, food and other industrial mixer to move over. According to the experience of long-term use of the site, in the selection of mud mixer should pay special attention to a few points:

Three key points to choose mud agitator

1. Rotation speed: Because it does not want the cuttings in the mixing process is further splintered, so the stirrer speed should not be too high, the energizer should choose between 50~60rpm. For more than 60rpm of mud mixer, recommended the user to take a cautious attitude.

2. Sealing: According to the experience of the use, as working conditions are very bad, the drilling fluid mixer shaft is not suitable for the use of end face seal, the general packing seal is also difficult to adapt. At present, the more successful is the use of multiple sets of V type packing. It has self sealing performance and self compensation ability, and long-term maintenance adjustments will not produce lubricating oil leakage problem.

3. The impller: There is a variety of mud mixer impeller, but it must be noted that: a small diameter of the blade, high speed of mud mixer, must be a small amount of circulation, shear force, and therefore does not apply to the use of drilling fluid solid suspension. Therefore, the diameter of the impeller should be larger.Second, pay attention to the turbine type impeller has been widely used in the drilling fluid mixer, which is the best open type turbine, because there is no central disc, not to hinder the mixing of the upper and lower liquid phase of the impeller.
