Mono Screw Pump Working Principle and Apllication



Mono screw pump, also called sewage pump or progressive cavity pump, belongs to the rotor type positive displacement pump. 
Mono screw pump is depending 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.
Mono screw pump is an ideal pump used to feed drilling fluids to decanter centrifuge. Since mud is evenly pushed to proceed along the axial direction, the inner flow speed is kept low, volume unchanged and pressure stable so that vortex and agitation are prevented. Mono screw pump can also be used for wet mud drilling waste management and cuttings transportation.
KOSUN Mono screw pump features
The Mono screw pump shaft is made of stainless steel and even the whole pump can be made of stainless steel.
The stator is made of elastomeric material, so it gives the pump a more competitive advantage than other pumps to transfer fluids of high viscosity and fluids with hard suspended particles.
The advantages of mono screw pump are compact structure, small size and easy maintenance. Rotor and stator as wearing parts of this pump are simple to be replaced.

Water Based Mud Drilling Cuttings Management

In  geotechnical engineering ,   drilling fluid is used to aid the drilling of  boreholes   into the earth , o ften used while drilling  oil  and  natural gas  wells and on exploration drilling rigs , and  also for much simpler boreholes  like   water wells . Liquid drilling fluid is often called drilling mud. The three main categories of drilling fluids are water-based mud (which can be dispersed and non-dispersed), non-aqueous mud, usually called oil-based mud, and gaseous drilling fluid, in which a wide range of  gases  can be used. The main functions of drilling fluids include :  providing  hydrostatic pressure  to prevent  formation fluids  from entering into the well bore, keeping the  drill bit  cool and clean during drilling, carrying out drill cuttings, and suspending the drill cuttings while drilling is paused and when the drilling assembly is brought in and out of the hole. The drilling fluid used for a particular job is selected to avoid formation damage  and to limi

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 solid cylinders of rock or soil.   In cable-tool drilling, the drilling waste  i
