The centrifugal desander pump belong to the vane machine, it widely used in the oil field, mainly used conveying the crude, infused water into the stratum, it is very important in the drilling fluid solid control system, is mainly used to extract the drilling fluid with viscosity and have solid particles.
The centrifugal pump is the power source of the desander, desilter, hydrocyclone device in the drilling fluid solid phase control system, because the drilling fluid is the medium of the deander pump, while the drilling fluid is the suspension fluid with a lot of solid phase particles and all kinds of Chemical additive, so the impellers and the material of volute must have the wear resistance and corrosion resistance.
Usually the centrifugal pump is divided into desander pump, desilter pump according to its functions.
The centrifugal desander pump is a special type of the centrifugal pump, it is called desander pump in oil field, it is very important in the drilling fluid solid control system, it is used to extract the drilling fluid which has a certain viscosity and solid phase particles, Because the medium of the desander id drilling fluid, but the drilling fluid have a lot of solid phase particles and all kinds of suspension of the chemical additive, so the material of the desander impellers and volutes must have abrasive resistance and corrosive resistance. In order to prevent the solid phase particles rub the pump, we can put rubber in the pump.
