Desilter cones vary from desander cones only in Proportions and work on exactly the same principles. Frequent desilter cone sizes are in between 2 and 5 inches. A centrifugal pump need to be committed to supply fluid on the desilter manifold only.
Desander: Very best suited to the Original phase of solids Management where by greater particulates should be taken out.
The Derrick spherical and inline desilters are built to remove silt-sized (twenty to seventy four microns) solids from drilling fluids. Derrick’s spherical desilters are easy to function and simple to maintain. Optional shutoff valves on Each and every round desilter cone inlet permit person cone removal and inspection without the need of interrupting Procedure of your desilter.

The dispersed particles shift downward inside a spiral route into as underflow while the cleaner and lighter density liquid mud travels up through a vortex in the center with the hydrocyclone, exiting as a result of piping at the top from the hydrocyclone. Desilter cones are 4-6 inche diameter to get rid of wonderful sands and silt particles right down to twenty micron. Hydrocyclones are created of polyurethane as a consequence of its have on resistance and fewer bodyweight than metal.
Use of desanders is mostly not Expense-efficient with the oil-base drilling fluid because the larger cones discharge a major degree of the liquid stage.
Another reason for at least 3 % underflow is the fact, at reduce costs, the size of particles that should be eliminated is unfavorably influenced, as a lot of stable will continue to be inside the fluid.
During the drilling field, the use of desanders and desilters is important for preserving the quality and general performance of drilling fluids. While both serve the objective of getting rid of reliable particles with the fluid, they target diverse particle sizes and function with a few distinctions.
Given that the entire fluid stream must be processed the hydrocyclone capability for every treatment must be desilter in surplus of the most pump volume in the rig pumps. And since the measurement, and so capacity, of the hydrocyclone is in follow mounted by the dimensions of particle it really is intended to take away, the one way to obtain the needed processing capacity is to improve the quantity of models Doing work in parallel.
La tolva de lodo es impulsada por una bomba centrífuga que hace fluir el lodo a alta velocidad a través de una boquilla venturi (chorro) debajo de la tolva de forma cónica.
The centrifugal pump sucks out of the tank. The underflow from the prime of the desanders is discharged into the tank downstream. These two tanks must be related by an equalizing valve at The underside of the tanks.
Periodically inspect and manage your desander and desilter systems. Check for wear in hydrocyclones, blockages in discharge nozzles, or any erosion that may affect functionality.
Although both of those pieces of kit are critical, your price range will likely play a essential role. Desanders normally Charge more due to their larger sized dimension and better flow capability.
