mud agitator type schottel free sample

Derrick mud agitators include an explosion-proof, “C” faced motor, reduction gearbox (helical-bevel gears for horizontal agitators or all helical gears for vertical units), impeller, and shaft with assembly bushings. Motors range from 5 to 30 HP and may be supplied in several power configurations.

Attaching the motor directly to the gearbox protects correct alignment that can increase bearing life and provides 95 percent efficiency in power transfer to the impeller. Using this superior design surpasses standard worm drive gear assemblies by 30 percent, allowing Derrick agitators to do the same work at far less horsepower. By unitizing the motor and gearbox, weight and space requirements are reduced. Horsepower, mechanical configuration, impeller diameter, and shaft length are customized to tank dimensions and maximum mud weights. Available horsepower ratings* are: 5, 7.5, 10, 15, 20, 25, and 30.

Mud agitators are fluid mixing equipment that keeps solids in drilling fluid suspending, no deposit in the mud tank bottom. It uses its impeller to agitate and mix the drilling mud to prevent solid particles from depositing in the tank or mud pit.

There were many types of mud agitator, depending on purpose demand, gearbox type, and working conditions. But the basic structure of the mud agitator is all the same: Motor, gearbox [Speed reducer], shaft, and impeller.

Yes. Some clients prefer the hydraulic drive for some specific use. Some clients need a vertical agitator. And some clients prefer the stainless steel shaft and impeller. Different applications and industries will request equipment much different If you have questions or demand on mud mixers, please let us know and we’ll help you to get the ideal solution.

For oil and gas drilling, there are different configurations on tanks number, tanks size, so it’s not easy to confirm. But we can take a system as an example. One mud system laying with 6 tanks, and tanks size are 9 m X 2.2 m X 2.3 m. The normal proposal is 3 sets of agitator per tank. But there is a shaker tank, then we deduct 1 set. So, probably we need 17 sets of the agitator. And the agitators are APM 7.5 driven by 7.5 kw motor.

The most important factor was the power of the mud agitator, 5.5 Kw agitator is cost far lower than 22 KW. There is apparently a different price between the explosion-proof type and Non-proof type. Higher explosion-proof grade means higher cost.

Worm gearbox type mud agitator is a common type, durable, and easy maintenance. But its efficiency lower than the bevel gearbox. so bevel gearboxes are generally more expensive than worm gearboxes for the same HP and gear ratios. Helical-worm and helical-bevel are advanced generation type of worm and bevel gearbox. They produce less vibration and noise. The planetary gearbox is mainly used in vertical agitator.

Fluid Systems mud agitators are designed to mix and suspend the solids using axial flow, promoting low particle size degradation and effective polymer shear. Unlike mud guns, the FSI mud agitator is relatively a low energy device, easy to operate and inexpensive to maintain. Our standard horizontal and vertical mud agitators range in 5 to 30 horsepower with an explosion proof motor and gear reducer. We size mud agitators according to the configuration and maximum mud weight.

For the PSV´s carrying drilling mud to the oil platforms it is important to keep the mud homogeneous, otherwise there will be severe sedimentation. The drilling mud is expensive itself and a delay in time, waiting for the drilling mud to be mixed is even more expensive.

Hassle free operation and ease of maintenance of the agitator is an important factor in the operators ability to supply the platforms without costly delays.
