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 timesoften 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.

Mono Screw Pump Working Principle and Apllication

M ono screw pump , also called  sewage pump  or  progressive cavity pump ,  belongs to the rotor type positive displacement pump .   M ono screw pump  is depend ing  on the screw meshing with liner on the discharge and suction cavity to conveying liquid volume change.   It is a kind of method of pressurized screw pump, a main working parts by bushing has a double helix cavity (stator) and the stator cavity and its meshing singlehead screw screw (rotor).   When the input shaft through the universal joint drive making planets revolving around the center of the stator, rotor stator, rotor, vice is continuous mesh form sealed cavity, the seal chamber volume invariably uniform axial movement, the medium from the suction end of deputy to the stator, rotor pressure side, the suction medium sealed cavity through the stator without stirring and destruction. M ono screw pump  is an ideal pump used to feed drilling fluids to ...

Drilling Waste Management Solutions

With the increasing attention to environmental protection, drilling waste randomly disposal has been seriously forbid by many countries. Considering the global need of such kind of equipment need, KOSUN  focused on drilling waste management solutions for many years. Contamination of drilling fluids  with drilled cuttings is an unavoidable consequence of successful drilling operations. If the  drilling fluid  does not carry cuttings and caving  to the surface, the rig is not either “making hole” or soon will be stuck in the hole it is making. The drill cuttings that are separated from the drilling fluid on the surface by the so lid s control equipment and some quantity of unrecoverable or economically unwanted drilling fluid are a major source of drilling waste. Drilled and formation solids that are sized smaller than can be removed by the solids control equipment are often reported as drill solids. Some quantity of drill s...

Drilling Waste Management Approach and Method

Drilling waste management is a hot topic these years with global attention to environmental protection, especially in O il & gas industry. Drilling waste management  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 ing   waste   is  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 ing waste  is commonly examined to make a record (a  well log ) of the subsurface materials penetrated at various depths. In the oil and gas industry, this is often called a  mud log .   One drilling method that does not produce drill ing   waste  is  core drilling , which instead produces s...
