Impeller of drilling mud agitator

2012-12-03

Stir action of drilling mud agitator is produced by moving blade, so the blade shape, size, quantity and rotate speed will affect agitator function.

 

Common agitator impeller can be roughly divided into four types: paddle-type, open-type, disc turbine and push type. After a long experience in the production of the accumulation and test research, various types of impeller size of the relative relations have a general range, if designed impeller more than the range, no matter appearance or performance will not ideal.

 

At present in home and abroad petroleum solids control equipment, the most common used agitator impeller only two types, one is open-type turbine, another is disc turbine. Rarely choose paddle-type and push type. In open-type turbine the used most is flat blade. In disc turbine can use flat blade, rider and backward curved vane.

 

Because of open-type turbine even without baffle also has strong fluctuation convection, so widely used in advanced drilling mud agitator.
