What are the structural design considerations of the Mud Agitator and what are the characteristics

In the oil drilling fluid solids control system, turbo-worm agitators are currently widely used, and some well teams also use helical gear agitators. The turbo-worm agitator consists of an explosion-proof motor, a turbo-worm reducer, a base and a stirring rod. It has the characteristics of simple structure, large torque, stable performance, convenient maintenance, etc., and has been widely used in major oil fields.

1. Using worm/worm gear reducer; compact structure, good meshing performance, reliable work

The mud agitator has a sturdy structure, a solid and reliable skin, and a compact size. The aspect ratio of the mud agitator is approximately 1:1, so the center of gravity is low and the stability is good. When the impeller encounters an instantaneous impact load, it is safer.

Because the mud agitator is equipped with a simple and high-strength unipolar worm gear reducer, it runs smoothly and evenly. The ability of the worm gear to withstand shock and vibration is more than 50% higher than that of the helical gear two-stage reduction gear of the corresponding specification. When the speed ratio reaches 60:1 and 80:1, the efficiency of the turbine transmission is lower. However, the reduction ratio of the new worm gear transmission is 20:1. Practice has proved that it has extremely high efficiency and shows the advantages that other types of gear transmissions do not have.

2. Combination of explosion-proof motors, suitable for working in harsh outdoor conditions

All use explosion-proof T-type frame, 3-phase 230～460V, 1150 rpm, frequency 60 Hz; or 3-phase 190～380V, 958 rpm, frequency 50 Hz. The motor uses elastic coupling and reducer directly Connected. A strong steel passport is mounted above the connecting shaft.

3. The explosion-proof motor and the input shaft of the reducer are directly connected through an elastic coupling, and the rotation speed of the stirring pulsator is constant

The solid mild steel shaft is connected to the reducer with a rigid coupling. In order to adjust the height of the impeller, a keyway is opened in the lower part of the shaft. The diameter of the shaft ranges from 38.1 mm to 88.9 mm, depending on the model. The actual length of the shaft is determined by the user

4. Double-layer impeller design, more sufficient mixing. The explosion-proof motor is placed horizontally, which is very convenient for installation, adjustment or replacement.

The reasonable stirring amount calculated by each agitator is related to the given power and impeller diameter. The relationship between the mixing range that the impeller can reach and the specific gravity of the mud and the required power can be determined by calculation.

To correctly choose the size of the mud agitator, the first step is to find out the width of the tank on the right side of the graph. Then there is a corresponding impeller diameter recommended value along the horizontal line on the left side of the figure. The size of the impeller is related to the specific gravity of the mud and the required horsepower. It can be simply drawn from the diameter of the impeller to the predetermined curve of the specific gravity of the mud according to the horizontal line. At this time, find the closest thick curve to the right of this point and write down the power value required for the upper part of the thick curve.
