TSB Series Centrifugal Sand Pump with Open Impeller Combination Seal and Antiwear Nodular Iron for Oilfield Drilling
1.Usage and Application Range
TSB series centrifugal sand pump mainly supplies to solids control circulating
system of oilfield drill rig,and be used to provide drilling liquid with a certain
discharge capacity and pressure to desander, desilter and mud mixer,to assure these
equipments work efficiently.
The TSB10×8×14 centrifugal sand pump applies to over 3000-meter-long drilling
rigs , with big viscosity and specific gravity drilling fluid.The TSB8×6×14
centrifugal sand pmp applies to over 3000-meter-long drilling rigs.The TSB8×6×11
centrifugal sand pump applies to under 3000-meter-long drilling rigs,also can be can
be used to supply mud to triplex mud pump as a filling pump.The
TSB6×5×14/6×5×11 centrifugal sand pump applies to truck-mounted drilling rigs or
pocket drilling rigs.The TSB4×3 centrifugal sand pump is usually used as
measuring pump or replenishment pump.The TSB3×2 centrifugal sand pump is
usually used as clean water pump.
2. Main Structure ,Feature and Working Principle
Its main parts are pump shell, impellers, bearing block, pump axle, bearing, shaft
coupling,wearing plate, seal apparatus, oil seal, motor and base.
The Series Centrifugal Sand Pump has these features: (1)open impeller,apply to
transport high viscosity drilling liquid. (2)combination seal for a long service life.
(3)use universal bearing houses and bearings,convenient to maintain and cut the
costs.(4)the major parts are made from antiwear nodular iron,and long service life.
The prinple is that under the motor, the impellers of the pump rotate at high speed,
the dring fluid is sucked into the suction pipe. After the drilling fluid flows through
the suction pipe and gets enough energy and velocity under the centrifugal force, the
drilling fluid is expelled continuously out of the pump.
