Structure, Characteristic and Some Notice in Use Process of Shear Pump in Drilling Fluids Solids Control

Nov 05, 2013

Shear pump is a special purpose equipment of quickly preparing and treating the drilled fluids. Drilling mud shear pump can allocate and deal with the mud rapidly, can match the requirement of allocating the high-performance mud. It can largely quicken the dispersion of clay particles, enlarge the surface area of clay particles and meet customers’ requirements of preparing and treating the high property mud, making the mud obtain the good rheological properties and cutting the drilling cost.

Structure

Drilling mud shear pump is one kind of centrifugal pump. The shear pump is composed of impeller, volute, support, packing case, transmission shaft, pulley, combination belt and electrical machine. The impeller of the shear pump is different with the water pump, the structure is more complex. It is the core part of the shear pump, with high efficiency. The impeller is made up by 5 parts: axial compressor turbine, stock solution tank, pump impeller, pressure cabin and shear plate. The axial compressor turbine, pump impeller and stock solution tank were casted critically as an ensemble by stainless steel, the structure is very compact.
 

Shear Pump
 

Characteristics

The shear pump can mix and hydrate fully the materials which were added into the mud, save the usage of mud materials, shorten the mix time and 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.

Some Notice In Use Process

1.  After using shear pump, we should use clear water flush pipeline and shear pump, to avoid leftover block runner and nozzle of impeller.

2.  Bearing bore is filled in grease about 10~20 ml every other week, combination seal cavity is filled in grease about 10~20 ml every day.

3.  In winter, if the pump is not used for a long time, drilling fluids in pump shell should be discharged, to avoid drilling fluids freeze.
