Sand pump solid control equipment, oil drilling drilling solids control equipment / solids control equipment 

 The current domestic oil drilling solids control equipment sand pump, water parameters are generally chosen design, the drilling fluid pump performance will be the solid phase particle size, concentration and density. At the same time, the wear resistance of solid, has accelerated the flow of abrasive and seal failure, the pump performance degradation, shortened life expectancy. SB Series sand pump is based on solid-liquid two-phase movement of the pump field and pressure field distortion rule, according to experimental parameters of the pump level to determine the best non-mining factor therefore, the hydraulic design to conform to the body in two-phase flow the movement of the pump. SB Series sand pump impeller in the form of semi-open, fewer leaves, smaller leaves of radial, blade width of the larger, the larger the blade inlet angle, outlet angle smaller blade profile for the logarithmic spiral, to confirm 
 The inhalation, wear resistance, and more efficient than the arc lines of 6% -10% leaf. SB Series sand pump room with quasi-spiral vortex, vortex chamber with rectangular cross section. To confirm that good water resistance and resistance to tempering. SB Series sand pump vortex chamber and impeller area ratio designed to control the throat velocity, making it flow in a certain range, high efficiency, wear resistance. 
 SB Series sand pump shaft seal and pump seal has its unique structure, characterized by solid particles falling into the shaft control room, changing two-phase flow for single phase flow, and change the sand pump seal for the conventional pump seal. Sealed slot and leaves the fixed combination of cyclone structure. To confirm the sealing structure is superior to other sealing structure, reflecting the long life, reliable operation and simple maintenance features. 
 SB series of short stretch of sand the shaft, rigid, curved bay, visibility is good, with beauty.
