Principle of Operation and Characteristic of KOSUN Oil Drilling Mud Shear Pump

Oct 24, 2013

Drilling fluids shear pump is a special purpose equipment in solids control system which can meet all customers’ requirements of preparing drilling fluid for the well drilling. KOSUN Drilling Mud Shear Pump is used to treat the high property mud, make the mud to obtain good theological properties and cut the drilling cost as much as possible.

Shear Pump is the new-type equipment of petroleum and gas for solids control in drilling. Considering the terrible working environment of the shear pump, KOSUN had special requirements for both manufacturing and purchasing pivotal accessories to prolong the service life. Impeller and packing box are both manufactured by high-quality stainless steel; mechanical seal and importing oil seal, as well as erosion-resisting dope and so on can ensure that the shear pump has long service life, high pump efficiency, leak-free oil seal, reliable working and easy maintenance, of which can meet clients’ requirement of configuration and disposing high-performance drilling fluids.
 

Shear Pump
 

Principle of Operation

The shear pump adopts a set of mechanical seal for no leakage at stuffing box. Inside pump is a series of stainless steel turbine containing nozzles, four scoops and shear plate. Fifty percent of the fluid is sheared twice each time through the pump. This turbine shear pump is mounted on a special base with belts and sheaves to drive pump, belt guard and a explosion-proof U/L approved electric motor. Included is a special hopper with nozzle sized for this application and one mud kit as a package in order to build a complete shear and hydration system. The pump is designed to give longer service life through the improved shaft seal.

Characteristic

The shear pump can mix and hydrate fully the materials which were added into the mud, to save the usage of mud materials, shorten the mix time and to supply good-performance mud for the drilling. The shear pump can increase the hydration degree of the particles, quicken the attenuation and hydration of the polymer and offer a high output volume and lift to match the requirement of preparation and mud.

The shear pump always works with jet mud mixer in a solids control system, the combination of them is so efficient in drilling fluids configuration. They are usually installed on the drilling mud tank. KOSUN is a professional in solids control equipment and system, including shale shaker, mud cleaner, mud gun, mud agitator, desander, desilter, etc.
