There is an array of main parts in the drilling equipment in spite of the fact that some uncertainties still remain in the prediction of the oil drilling operation data. Thus, to increase the pressure rise over the main parts in the drilling equipment, more impellers need to be connected in series so that the return channel of the drilling equipment is capable of leading the fluids from one impeller to the next.
In other words, the impeller and the main parts in the drilling equipment return channel are built in different chambers along with some multistage pumps in the drilling equipment stack. Apart from leading the fluid from the main parts in the drilling equipment impeller to the next, the return channel has the same basic function in terms of converting main parts in the drilling equipment dynamic pressure to static pressure since the return channel will not reduce unwanted rotation in the fluid. What is more, because such a main parts in the drilling equipment rotation will eventually affect the performance of the subsequent impeller, the rotation is controlled by guide vanes, which is especially true in the multistage inline main parts. This is because the fluids come from the top of the main parts in the drilling equipment chamber stack to the outlet in the channel formed by the outer part of the stack and the outer main parts in the drilling equipment sleeve.
In addition, it has to be noted that when engineers are designing a drilling equipment return channel, the same design considerations of impeller and volute casing should be taken in the first place so that the channel will not create radial forces on the impeller. At the same time, it is well known that main parts in the drilling equipment play an important role in removing the contaminants in slow sand filters that might occur in different oil drilling layers, which is especially true in the case of active layer that is marked by main parts in the drilling equipment ripening period of more than six weeks.
This is because it takes a while for the layer to be formed during which time main parts in the drilling equipment can have their filter performance. As a matter of fact, at present, a series of devices have been used to visualize the ripening process of the drilling equipment sand filter over a period of eight weeks. To achieve this, main parts in the drilling equipment need to deal with sand particles that are removed at weekly intervals so that the removal of slow sand filtration can be fully understood with the help of the process visualization.
