Products Description
Description
Centrifugal pump, also called sand pump, is widely used in the solids control system and drilling mud system. It can be taken as the feeding pump for the mud cleaner, desander and desilter, and mixing pump for the jet mud mixer, as well as supercharging pump for the mud pump or trip tank. Therefore, the centrifugal pump is named as desander pump, desilter pump, mixing pump, weighting pump or trip pump for different functions.
Structure
The structure of the horizontal centrifugal pump is simple too, including the base, motor, coupling and pump head assembly. Usually, in the solids control system for a drilling rig, the sand pump motor shall be explosion proof.
Working Principle
The motor drives the shaft of the sand pump to rotate through the coupling, then the power is transmitted from the shaft to drive the blade rotating. The drilling fluid is sucked in from the blade center and pass through the channel, then obtains energy and speeds up with the action of centrifugal force, and as last reach to the separation equipment. Sand pump transfers drilling fluid with a certain pressure and displacement to ensure these equipment work normally and efficiently.
Function
Horizontal centrifugal pump is to convey drilling mud and transfer energy.
Centrifugal Pump Characteristics
Ø Adopting combination seal of mechanical seal and packing as auxiliary to prolong service life greatly.
Ø Streamline design on the impeller and pump shell.
Ø Flow parts is made of high wear-resistant cast iron.
Ø The sand pump shell is made of wear-resistant alloy ductile iron, with higher wear resistance function.
Ø The impeller is made of wear-resistant alloy ductile iron, which has a longer service life.
Ø International famous brand bearings to ensure stable operation and long service life.
Ø Famous brand explosion-proof motor made in China to improve equipment quality and safety.
Ø Low noise, no pollution, stable operation.
