How to improve sand pump work efficiency?

Sand pump is also called centrifugal pump, since its working principle is according to centrifugal force. sand pump is power source for desander, desilter , swirl mixer in drilling mud solids control system. Therefore, work efficiency of sand pump will directly influence the whole drilling mud processing system work efficiency.

Some factors that will affect sand pump

  1. The larger capacity, the larger power

Increase hydrocyclone quantity or start more mud agitators will be request to enhance power.

  1. The higher speed for impeller, the larger power

Speed increase will lead to head rise, and then capacity increased.

  1. The bigger diameter of impeller, the larger power

Increasing impeller(can replace sand pump impeller) diameter will lead to flow and head increased, therefore, higher power requested

Sand pump worn means lower performance, so capacity, head, and power will be reduced.

  1. Motor power increased in closed pipeline

After start motor, if the load is small, it may cause an overload. At this time, when start we should close the discharge valve and then slowly open the discharge valve after starting.

  1. The higher density of drilling mud, the larger power

Usually according to solids control equipment treating Max.density of drilling mud to choose pump power, or choosing a little larger motor ensure that are not overloaded in maximum aggravating drilling fluid case.

Aipu machinery through fully considering if matched equipment can work in best condition to design and pump parameter, most of the parts can be interchangeable, easy to operate and maintain, less leakage for oil seal, reliable work, long service life etc.

Pump structure

Sand pump structure in solids control is usually horizontal and pump driven by electrical motor directly. Some clients have special requirement on capacity and limit on many issues. Such as limited space but higher head or capacity requested, they will request much higher power motor or higher speed.

How to achieve the performance? Use 2 pole motor and then use the belt-driven connection, or the gear box, or the VFD panel to realize it

Other pump in the drilling fluids system

Besides sand pump, there are pumps called mixing pump, shearing pump. They are all centrifugal pumps, the difference including installation position, usage. Mixing pump is combination of centrifugal pump and mixing hopper. The shearing pump is centrifugal pump fit with special impeller to get drilling fluids sheared completely. Furthermore, there are screw pump or submersible slurry pump.

Based on usage, there is trip pump, super charge pump, water pump, centrifuge feeding pump, etc.

Aipu delivers over 200 sets sand pump every year. And solves much solutions on mud process. Come to us get proposal for you specially.
