DC Decanter Centrifugal Operation Principle

Separation of solids and fluid is completed within the drum. Its principle is high-speed rotating drum drive inner mud rotate speedily then the mud is thrown onto drum’s surface to make a fluid circle. Under the centrifugal force, solid sedimentary force in the separated liquid will be several hundred even thousands of times heavier than its own gravity so as to separate the solids from the suspension quickly. The ratio of centrifugal force which the solids have gained and the solid’s gravity is called as separating factor. The larger the centrifugal force, the finer the separated solids, so three types of centrifuge can get according to separating factor.

Hydraulic Coupler Operation Principle
Hydraulic coupler mounted on main motor, it is a hydrodynamic transmission device, have the function of buffering starting shock, reduce starting current and overload protection . 
It consists of shell, turbine, pump wheel, input shaft, output pulley; shell is joined with turbine, output pulley connect with shell; input shaft connect with pump wheel, working oil is filled into the shell, pressure emerges in service oil caused by centrifugal force when motor axle drive turbine to rotate, in this way, power is transmitted.
Motor’s no-load starting can achieve when motor start-up in lower speed because less liquid pressure and smaller drag exist at this time when reaching its rated rotational speed, oil pressure increase and drive load to rotate, this is coupler’s buffering starting shock principle; When load is too heavy, speed differential between pump wheel and turbine increase , oil heated in real time, soften in a position enter the coupling are going to be liquid once oil temperature exceed 120°c, oil sprays resolute create input cut loose output, so main motor is protected and make certain no burn happens, oilis that the media of transmission, therefore its performance can influence coupler’s operating condition. Replace the oil pro re nata.

Gear Box Operation Principle
Differential gear in reality may be a secondary planet delay gear, there's ring gear within the shell internalprocess. the shell is revolved with the roller, the left belt pulley-block drives the primary gear wheel on the input gear rotate, the primary gear wheel engaged with the ring gear of the shell through the primary cogwheel, by doing this, the shell rotating speed and also the input bearing rotating speed combined into a primary tumbler’s rotating speed,and the secondary gear wheel output the combined speed to the second half, the transmission principle of the second half is that the same with the primary one, and at last drives the propellor rotate through the output bearing.

Drilling Cuttings & Drilling Waste Separation Development

Drilling waste separation from the mud at the sedimentary rock shakers is also coated with such a lot mud that   square measure|they're unsuitable for the  drilling fluid recycle or disposal step or are tough to handle or transport. Constituents of the drilling cuttings or the mud coating them, like oil or metals, could leach from the drilling waste, creating them unsuitable for land application or burial needs. forms of materials will be other to drilling cuttings to solidify and stabilize them.  Solidification could be a technology that encapsulate the drilling waste  in an exceedingly monolithic solid of high structural integrity. The encapsulation is also of fine drilling waste particles or of an outsized block orinstrumentality  of drilling cuttings .  Solidification doesn't essentially invol...

Drill Cuttings Disposal Management

Drill cuttings disposal is a hot topic these years with global attention to environmental protection, especially in O il & gas industry. D rill cuttings  disposal into environment without any treatment is strictly forbidden. So before disposal, a series methods must be introduced to treat the cuttings and make it reach to disposal standard. Drill cuttings are produced as the rock is broken by the drill bit advancing through the rock or soil; the cuttings are usually carried to the surface by  drilling fluid  circulating up from the drill bit   by  rotary ,  percussion , or auger methods. The drill cuttings are commonly examined to make a record (a  well log ) of the subsurface materials penetrated at various depths. In the oil industry, this is often called a  mud log .   One drilling method that does not produce drill cuttings is  core drilling , which instead produces solid cylinders of rock or soil.   In cable-tool ...

Screens Types Selection and Usage in Shale Shakers

S olids control equipment s hale shakers typically co mposed  of wire mesh  shaker screens  in  kinds of  mesh sizes that vibrate the drill waste  across and off the shaker screens as the drilling fluid or drilling mud flows through shaker screen s   in the solids control system and back into mud system.  Usually there are  three types of shaker screens for different shale shakers, including  PWP screen, PMD screen, and hook strip screen. PMD scree is Derrick ’ s patented products for Derrick 2000 series and Derrick 500 series shale shakers. While hook strip screens  and PWP screens are w idespread a pplication to  world famous shale shakers like brand Derrick, Brandt , M-I SWACO, and KOSUN. The steel frame shaker screen  is the most commonly shaker screens composed of steel frame and two or three  layers SS304  cloth.   Frame shaker screen  is commonly used ...
