Differences between Centrifugal Pump and Shear Pump in Drilling

Posted by:    Time:2014-01-01     click:

Centrifugal pump is a sub-class of vibrant axisymmetric work-absorbing turbo machinery. Centrifugal pump in accordance with the working principle of shear pump are applied to transport fluids by the conversion of rotational kinetic power to the hydrodynamic power of the fluid flow. The rotational power normally arrives from a motor or electric powered engine. The fluid enters the pump impeller along rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from in which it exits.

Typical utilizations consist of water, sewage, petroleum and petrochemical pumping. The reverse purpose of the centrifugal pump is a water turbine converting prospective power of water stress into mechanized rotational power.

Chengdu west petroleum equipment co., ltd sequence centrifugal pump is applied for transferring drilling mud. It can be applied as feeding pump for desander, desilter or applied as blending pump for jet mud blender. Also it can be applied as trip pump, and supercharging pump for rig mud pump.

Shear pump

Shear pump like the mission pump is applied to successfully blend and hydrate materials what are added into drilling fluid. With big capability, higher lift, and extended service life, the shear pump can pace up dilution and hydration of polymers to have property mud.

Shear pump is on the frame of present centrifugal pump concept, via the development to create a new, effective centrifugal pump, is created for fast preparation and dispose drilling fluids in the solids handle equipment technique. The principal request is shear polymer clay, it can blend materials successfully, completely hydrate materials, help save materials making use of, shorten drilling fluid preparation time, provide beneficial drilling fluid overall performance to drilling procedure.

Functions and advantages of Chengdu west petroleum equipment co., ltd shear pump

1. enhance the hydration degree of particles

2. save betonies above 30%

3. dilute, shear and hydrate the polymer

4. the shearing pump has a big flow percentage and lifts. It can encounter the necessities for generating up and disposing mud.

Chengdu west petroleum equipment co., ltd is capable of delivering purchasers with this kind of three series as oil & fuel drilling solids handle equipment, centrifuges and drilling waste materials administration equipment. All above includes 25 groups of productions, which are extensively applied in essential oil & fuel drilling, shale fuel drilling, water well, geothermal well drilling, trenchless horizontal directional crossing assignments, mine gravel staged therapy, tailings therapy, rive dredging works, environmentally friendly sewage therapy, waste materials oil recovery and purification therapy, and so on.
