WJQ5′6J-10 shear pump is a uniquely designed pump special for shearing polymers and clays。Both site use and theory demonstrate the pump is an effective machine。Its shearing function is mainly accomplished by the specially-structured impeller and shear wheel. To full play the effects of drilling fluid and improve the drilling fluid properties，the polymers or clays should be highly sheared before adding them to the drilling fluid system。If the polymers or clays are not highly sheared，in the first cycle，the polymers may jam the strainer and will result in losing amount of polymer and increasing drilling costs，and the large-size solids in the drilling fluid will harden and difficult to clear away as well. Besides，these not highly sheared polymers will produce many pearl eyes in completion fluid, and these peal eyes will damage strata and reduce the permeability of strata。Facts have proven that the WJQ5′6J-10 shear pump is of excellent performance，and can apply the high shear necessary to rapid hydrating polymers and clays，which solves the outstanding problem caused by bad hydration of polymers or clays in drilling fluid or completion fluid。Moreover，using the WJQ5′6J-10 shear pump reduces the bentonite consumption over 30% and polymers consumption over 15%。It also reduces loss of fluid and mud cake，improves gel strength，and slows the shear rate viscosity of drilling fluid。All those advantages mentioned above as well as the more reliable shaft seal structure and more convenience in operation and maintenance make our WJQ5′6J-10 shear pump come up to a world advanced level in the same products。
