This design allows for the efficient extraction of drilling mud gasses and control of the sample collection chamber. This is an improvement over other extractors that act much as a centrifugal pump and spit drilling mud from the side. The long vertical tubing also acts as a condensation tower that helps eliminate much of the water vapor in the extracted sample.

Introduction HMA series agitators are heavy-duty mechanical mixers for viscous fluids specially designed for seal type tanks. Several models are available to meet a variety of mixing needs. The naming convention for these models is: HMA-X where X = the horsepower of the unit. For example, HMA-20 is the 20 hp mud agitator for seal type tanks. Each HMA series agitator uses a pipe-spool shaft and impeller(s) to maintain a homogeneous mixture of liquids and solids within a tank. Impellers have contour blades (axial flow), and may be installed in multiple configurations to provide the desired results. The impeller shaft is suspended from and attached to the output shaft of the low-profile, skid-mounted gearbox. The gearbox uses a worm-worm gear drive system to reduce the rotational speed of the explosion-proof motor to drive the impeller(s). HMA series agitators are available in models ranging from 25 to 40 horsepower, and can be seal base unit or shaft seal units. Impellers range from 54 inches (1372 mm) diameter to 84 inches (2134 mm) diameter.

Motor The motors used on Brandt mud agitators are explosion proof, T-frame, three-phase electric motors directly coupled to the gearbox using a flexible coupling with a solid steel guard. Motors are available for most voltage/frequency requirements. Other electrical code styles and temperature ratings are also available.

Gearbox The gearbox is a triple reduction worm-worm gear drive, reducing the motor speed (900 rpm @ 60 Hz) to the agitator speed (30 rpm) in a single 30:1 reduction. The gearbox contains an output shaft, two seals, and four to six bearings in addition to the worm-worm gear. The bearings are spaced to minimize shaft vibration and deflection, and seals are readily obtainable standard sizes. Unlike many competing agitators, Brandt’s gearbox requires no manual lubrication of the bottom output bearing.

Contour-blade impellers On contour blade impellers (Figure 2-1), the blades are designed with a variable pitch reducing the horsepower requirements and inducing less shear to the mud. Contour blades move liquid downward to the bottom of the tank, along the tank bottom toward the tank walls, and then up the tank wall. All fluid in the tank is mixed continuously, and the same consistency is maintained in all parts of the tank. Field experience has confirmed that this design provides the most homogeneous mixture in the widest range of installations. Fluid agitation minimizes fluid control problems caused by inconsistent mixtures.

Impeller shaft HMA standard impeller shafts are manufactured of eight-inch pipe spools. The impeller shaft is coupled to the gearbox with a rigid coupling. Shaft length is determined by tank depth. When ordering impeller shafts, always specify the actual tank depth. Tank depth is defined as the distance from the bottom of the tank to where the agitator is mounted.

Bottom shaft stabilizer A bottom shaft stabilizer is required to reduce side loading on the gearbox bearings. The stabilizer also protects the agitator shaft and impeller when auxiliary equipment is carried inside the mud tank during rig moves.

2. Impeller rotation: The impeller should rotate clockwise when viewed from top. 3. Oil fill/breather plug: plug must be clear of any obstruction to prevent pressure build-up and possible seal damage. 4. Agitator should operate with no vibration. 5. Check rubber insert on input shaft coupling for wear and cracks. 6. For optimal performance, change the oil after the first five days of operation.

1. Inspect for oil leaks. 2. Keep motors clean and ventilation opening clear of mud build-up or other debris. 3. Check impeller shaft coupling for proper make-up.

HJBL series vertical mud agitator is mainly used for deep mixing and mixing in the mixing tank. The mixing shaft is longer than 1 meter and equipped with a stainless steel base to ensure that the mixer runs stably and does not shake during the mixing process.

Vertical mud agitator can be widely used in chemical industry (fine chemicals, pharmaceutical chemicals and daily chemicals), environmental protection (sewage treatment), pharmaceuticals, cosmetics, metallurgy, food, heat treatment cooling, leather processing and other industries.
