Drilling mud agitators are popular equipment used in oil drilling fluid system. The are mounted on tank top. Per different tank and mud property, the agitators motor and related parts will be configured different.

Drilling mud agitators shaft

We know mud agitator also called mud mixer. Mud agitator combined with motor and reducer. The auxiliary part to achieve mixture is shaft and impeller.  How to decide shaft length? Usually, our mud tank is square or rectangular one.

Drilling mud agitators

After calculating impeller diameter under special formula, we get impeller 900mm is proper. Then the shaft bottom should be about 360mm away from tank floor. For example, the tank height is about 2100mm. Then shaft total length starts from gear box is 1740mm or 1800mm will be ok

Mud agitators impeller

Many clients would also like to know impeller calculation. How to calculate it? We need to consider tank volume, mud density. TOR, impeller displacement, safety or all related factors. But usually, we have common configuration on impeller based on special theory and practice

Oilfield mud agitator

For example, if the tank sized 10x10x10' and agitate 16ppg mud we'll request an impeller sized 38". Motor is 10HP. However, to make sure the safe and reliable operation we suggest 40" as safety solution. Furthermore, tanks if deeper than 6feet, we suggest canted impeller blade for better performance than flat ones

All different mud agitators

Drilling mud agitators widely used in various application. Reserve mud tank, solids removal use, addition use, suction tank, pill tank, and so on

Related agitators will be configured per actual demand. From power, impeller type, size, agitator installation way, and so on. Then the reducer type, reduction ratio and so on

Drilling mud tank agitator is the necessary equipment to mix drilling fluid during oil drilling at oilfield. Mud gun can be used together with agitators as well.

Drilling mud tank agitator dimension

The mud agitator impeller size and power demand can be calculated against tank size confirmation. If we don't know the maximum density of drilling fluid we'd better set 2.4g/cm³ as standard. Then we can get sufficient safe data the complete agitation on any fluids will be achieved without any worries on motor over loading. Most oilfield mud agitators speed is 50-90rpm

The agitator impeller dimension will be calculated via each parts TOR. The TOR unit is "s" that means move all fluid in tank will take how long time. So, the tank volume and impeller discharge we'll get the impeller size

Detail calculation on impeller and power

For example, one drilling fluid is 30ft long, 10ft wide, and 10ft height. The maximum drilling fluid density is about 16lb/gal. If the drilling mud density is not assured we can treat it as 20lb/gal. There are totally 3 even compartment in this tank and all solids have been removed

Drilling mud tank agitator

Any fluid in any tank, the liquid level should be 1 ft lower than tank top. Based on above information we get one compartment volume is about 6732 gallons. Then as per sheet the TOR will be calculated as 64s. Compared with suggested value, the TOR is proper as the solid have been removed. If we need lower value for sooner liquid velocity we can select bigger impeller, if we need slower the smaller one will be ok. But we need re-calculation until get the precise value

According to above reference we know the 38" impeller for 16lb/gal liquid is Ok. But there is no value for 38" impeller then we toward to close one-40". Thus even higher density fluid to be agitated the safe data will work still. Then we select the agitator can be driven by 10hp motor. So, 38" impeller and 10hp are ok for agitator on this tank.

Drilling mud guns

Compared with mud agitator, the mud gun will mix or agitate drilling fluid via the nozzle. Drilling fluid after nozzle will flow at high speed. The pressure and velocity will be usually transferred by centrifugal pump. The mud gun will be almost used on compartment or compartment lower fluids.

So we usually operate mud guns together with mud agitators. They will agitate all drilling fluid more completely and throughly.
