There are some tips for desilter operator including the one concerning the oil drilling liquid's chemical characteristics. To be more specific, with the help of desilter and 518 centrifuge and according to the similarity and the affinity laws for desilter and 518 centrifuge, one can derive the size of the model from the specific conditions of the entire oil drilling system as well as the pumping system. In general, the installation of desilter and 518 centrifuge in a model at a scale in the real suction chamber so that the liquid level in the desilter and 518 centrifuge suction chamber can be modified in a gradual manner or a successive manner.

At the same time, the flow within the desilter and 518 centrifuge is measured with a flow meter and the rotating speed of the pump is measured with a tachometer, which is also true in the case of the oil drilling liquid on different drive speed of the centrifugal pump. Factors like desilter and 518 centrifuge life time and the number of the vortex also have some influences on the overall performance and the different patterns of vortex that are presented according to the water level and rotating speed of the desilter and 518 centrifuge pumps.

What is more, in the flow in front of the desilter and 518 centrifuge suctions, to obtain relevant conclusions a laser sheet may need to be used in order to offer a better light of the desilter and 518 centrifuge section and oil drilling operators can easily observe the fact that a lighter area in the section is corresponding to the air entrance into the desilter and 518 centrifuge. In other words, if the desilter and 518 centrifuge is analyzed in terms of air flow, other parameters can be calculated using a digital method and one can observe that at the inlet section there are two main patterns including desilter and 518 centrifuge central vortex entrance for high level and reduced flow rates in the part of lateral vortex.

As a result, the conclusion obtained by the analyzing of experimental data on desilter and 518 centrifuge with the help of hydrodynamic complex method is expected to allow the deduction of several correlations between the desilter and 518 centrifuge vortex frequency and the pumping debit in the suction chamber, which is especially true when the full areas represent the frequency of desilter and 518 centrifuge appearance according to the rotating speed and height in the chamber. Therefore, we may say that once the desilter and 518 centrifuge flow increase, the vortex probability increases as well and in the same time, the desilter and 518 centrifuge life time tends to increase.
