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.

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 Separation by Solidification and Stabilization

Drilling waste separation  from the mud at the shale shakers may be coated with so much mud that they are unsuitable for the drilling mud recycle or disposal step or are difficult to handle or transport. Constituents of the drilling cuttings or the mud coating them, like oil or metals, may leach from the drilling waste, making them unsuitable for land application or burial requirements. Kinds of materials can be added to drilling cuttings to solidify and stabilize them. Solidification is a technology that encapsulate the drilling waste in a monolithic solid of high structural integrity. The encapsulation may be of fine drilling waste particles or of a large block or container of drilling cuttings. Solidification does not necessarily involve a chemical interaction between the drilling waste separation and the solidifying reagents but may mechanically bind the drilling waste into the monolith. Contaminant migration is restrict...
