The working principle as well as design of the drilling desander has a history of over one hundred years. In modern society, the drilling desander plays a crucial role in chemistry, environment protection, food as well as drugs. As for the field of dealing with water, the drilling desander is able to remove grit, descend turbid and separate solid and liquid. And the most remarkable function of the drilling desander in oil drilling is to remove the unnecessary stuffs to get oil without any impurity. In addition, it also can be used in dealing with underground water and other water resources to clear away the solid particles in them through the technology of solid and liquid separation.

Generally, in order to make sure the high efficiency of the desander, it is necessary to run it under high voltage and rated current. And the ordinary working principle of the drilling desander is based on centrifugal setting and density differences. When the liquid is under some certain pressure, it is able to enter into the drilling desander from the inlet of the drilling desander. And then the strong swirling movement starts. Due to the different density of the grit and liquid, under the function of the centrifugal force, centripetal forces as well as fluid drag force, the liquid with lower density rises and discharges from the oil outlet while the grit with larger density discharges from the sand outlet on the bottom. And some fine grain particles that float and rise with the oil current will be filtered by the second filter unit to realize the purpose of degritting.

With the promotion of the modern science and technology, the newly created desander has the filter unit compared with earlier version. And the filter fineness can be adjusted according to the requirements of the users. This kind of drilling desander with filter unit has the features of high degritting rate, economical installation space, and low leakage rate to some tiny particles as well as stable working condition. Under some certain pressure limit and conditions, the larger the intake pressure of the drilling desander is, the higher the degritting rate is. And in some oil drilling engineers, it is better to uses several drilling desanders in parallel to meet the requirements of large scale drilling. And the most advanced drilling desander totally satisfies this working condition.

In conclusion, the drilling desander avoids the secondary pollution compared with other degritting methods. And its secondary gritting makes sure the high quality of the oil. In addition, the outstanding feature of the drilling desander is simple structure, low cost as well as convenient operation. What’s more, the most advanced drilling desander has large volume as well as large processing capacity, which saves the installation space and enlarges the application ranges and fields. Another important feature of this drilling desander is its small noise and long service life, which is beneficial to promoting the working efficiency of the oil drilling fields.
