What is the function of mud agitator? During the oilfield drilling construction process, qualified drilling fluid is the prerequisite guarantee for the progress of the drilling construction project. Drilling fluid agitator equipment prevents drilling fluid precipitation. If the drilling fluid precipitates, its viscosity will be too high, and the cutting speed will also increase. This causes the corresponding drilling pump pressure to rise, the pump to become difficult to start, the drilling speed to decrease, and the drill bit to easily become mud-packed, which creates difficulties in suction blowout. People often refer to drilling fluid as “drilling blood,” which shows its importance in the drilling process.
A drilling fluid agitator prevents fluid precipitation. This stirring device forces liquid and gas media to mix evenly through convection. The agitator’s type, size, speed, and power significantly impact mixing efficiency and uniformity.
Drilling fluid agitators primarily come in two types: those with a gear transmission structure and those with a worm gear transmission structure. Each offers distinct advantages and disadvantages.
Gear Transmission Agitators
These agitators use a gear transmission system.
Disadvantages: They generally have lower working reliability and are more complex to install. They can also be easily damaged during movement.
Advantages: Their reducer employs a single-stage worm. This design results in a compact structure, light weight, stable transmission, and low noise. They also provide high transmission power.
Worm Gear Transmission Agitators
In contrast, worm gear agitators feature a direct worm gear drive and often utilize a belt drive structure.
Key Characteristic: While typically larger in size, their notable advantage lies in their soft transmission. This “softness” provides significant protection for the motor against overload, which can be crucial in demanding drilling environments.
At present, the most commonly used mud agitators on the market are worm gear transmission structures. The worm gear transmission structure is simple, the speed ratio is large, and the working reliability is high. The application effect in the drilling fluid agitator is obviously better than the drilling fluid agitator with a gear transmission structure.
