Agitator Gear Box

Mud agitator is mainly composed of electric motor, gear box and impeller shaft assy, for shaft- connection type mud agitator, it also have coupler. Elastic coupling connect electric motor input shaft and agitator gear box input shaft. Impeller shaft and agitator gear box output shaft are connected by rigid coupling.

agitator gear box

GN agitator gear box is worm gear reducer, which is combined with explosion-proof motor, enable stable performance in wild severe environment.

Rotation of the drive motor is transferred to the impeller shaft through the directly coupled gear drive. The drive is a reduction agitator gear box and is factory assembled to the drive motor. The drive is sized to apply the maximum torque required to produce the design impeller rotation speed of 60 rpm under 50hz, and 72 rpm under 60hz.

The mud agitator stirs a mud slurry to maintain suspension of solids. The agitator is mounted on top of the mud tank and has one or two impeller(s) immersed in the mud slurry. The impeller shaft is directly coupled to an electric drive motor that is available in several horsepower ratings from 7.5 to 25.

There are 4 models mud agitator available, GNJBQ5.5, GNJBQ7.5,GNJBQ11, GNJBQ15. GN horizontal agitators utilize worm gear reducer. Welding type or casting type impeller for option. The updated GN mud agitator with the best brand gear box and use FAG bearing to last the gear box life.

The impeller is fixed to the shaft with bolts to avoid rotating or sway. Its vertical location on the shaft is determined as a height from the tank bottom corresponding to the impeller diameter times 0.75. If dual impellers are desired, straight blades are mounted on the bottom and the canted blade impeller is installed at a point about two-thirds above the tank bottom.

The keyed motor and driven impeller shafts are rigidly connected by a multi-piece coupling, which uses tapered locking bushings to secure the shafts together. Shaft lengths are customized to suit customer specifications. For shafts longer than 8’, a stabilizer is mounted on the tank bottom to support the lower end of the shaft.

Mud agitator maintenance

Mud agitator maintenance consists of checking gearbox oil level and oil condition and greasing gearbox bearings at required intervals.

1 Before operation, lubricate gearbox with L-CKE/P 220~320# worn gear oil or with L-CKE/P 320~460# worn gear oil.Verify that lubricant level in the gearbox reaches the bottom of the oil level plug.
