Mud mixer is a common equipment used in drilling operation control system, which is usually placed on the top of the slurry tank (circulating mud tank, supply tank, medicine tank). In order to prevent the drilling fluid solid particles from depositing in the tank circulation system, the circulation drilling fluid has stable performance, and the mixture is evenly mixed. Generally divided into horizontal mud mixer and vertical mud mixer. The domestic rig is mostly adopts horizontal agitator.
The horizontal mud mixer is the drilling fluid mixer, which is usually composed of a motor, a speed reducer, a mixer base, a stirring rod and a stirring impeller. The speed reducer and the impeller shaft are connected by rigid couplings. The impeller is composed of 4 blades welded. Its model is generally determined according to the size of the motor, the general can be divided into: 5.5Kw, 7.5Kw, 11Kw, 15Kw and 22Kw.
The mixing principle of slurry agitator: the impeller can cause the drilling fluid to generate vortex motion, thus enhancing the mixing effect. Clip in the leaves in the middle of the tray can also prevent downtime mud solid particles deposited around the underside of the leaves, used in this way, the utility model can reduce starting precipitates on leaf resistance moment, thus avoiding the starting overload and burn out the motor.
Worm gear and worm reducer are commonly used in the horizontal mud mixer, and the vertical mud agitator is used in the.The gear reducer is a new transmission device which uses the principle of planetary transmission. All the transmission device of the gear reducer of the gear reducer can be divided into three parts: the input part, the deceleration part and the output part.
Worm gear reducer is a power transmission mechanism, the use of gear speed converter, the motor (motor) the number of rotation to slow down to the number of rotation, and get a larger torque mechanism.
