Centrifugal pump definition and general information
Machine for moving fluid by spinning it using a rotating impeller in a casing with a central inlet and a tangential outlet
Such type pump commonly used in the handling and mixing of oilfield fluids. The rotary motion of a profiled impeller in combination with a shaped pump housing or volute applies centrifugal force to discharge fluids from the pump. Oilfield centrifugal pumps generally operate most efficiently in high-volume, low-output-pressure conditions. Unlike a positive-displacement pump, the flow from centrifugal pumps can be controlled easily, even allowing flow to be completely closed off using valves on the pump discharge manifold while the pump is running. This pump is also known as a "C pump."
Tips of oilfield centrifugal pump operation:
The path of the fluid is an increasing spiral from the inlet at the centre to the outlet, tangent to the impeller annulus.
Oilfield centrifugal pump
In the annular space between the impeller vane tips and the casing wall, the fluid velocity is roughly the same as that of the impeller vane tips. Power from the motor is used to accelerate the fluid entering the inlet up to the speed of the fluid in the annulus. Some of the motor power is expended as friction of the fluid in the casing and impeller.
These centrifugal pumps are developed and fabricated as supporting pumps based on requirement of transferring oil & gas drilling fluid. Centrifugal pump adopt the axial sucking structure and all the hydraulic components are wear proof cast iron, which is suitable for delivering the corrosive liquids with suspended particles in well drilling.
SB centrifugal pumps are characteristic of abrasion resistance, smooth and stable running, reliable sealing, long service life and convenient maintenance. Those pumps have been used for land and offshore drilling platforms in more than 20 countries over the world.
Clockwise pumps and anti-clockwise pumps are available.
Centrifugal pumps can be designed as clockwise or anti-clockwise. But they can't be fabricated both clockwise and anti-clockwise.
Mechanical seal and compound seal are available. The compound seal adopts auxiliary impeller, special oil seal and packing seal. Main seal of mechanical seal is mechanical seal with a long service life, auxiliary seal of machine seal is packing seal to prevent occurrence of accidents.
Shaft seals are lubricated with grease and bearings are lubricated with machine oil and grease since bearing covers at two ends of bearings are equipped with grease injectors. Both inlet flanges and outlet flanges for centrifugal pump are with two series standard dimensions.
Centrifugal pump are widely used in oilfield drilling equipment and drilling mud equipment like shale shakers, desanders desilters etc. Welcome to consult us for oilfield centrifugal pump.
