What is the composition of oil drilling fluid desander?

HCS desander is mainly composed of vibrating screen, bracket, electric control box, pressure gauge, manifold, cyclone, etc.

Working process: The pump transports the sand-water mixture to the cyclone. The fine sand concentrated by centrifugal classification is supplied to the vibrating screen through the grit nozzle. After the vibrating screen is dehydrated, the fine sand and water are effectively separated, and a small amount of fine sand, mud, etc., is returned to the vibrating screen.

The tank returns to the cleaning tank, and when the liquid level of the cleaning tank is too high, it is discharged through the discharge port. The weight concentration of recovered materials by the linear vibrating screen is 70%-85%. 

Adjusting the fineness modulus can be achieved by changing the pump speed, changing the mortar attempt, adjusting the overflow water volume, and replacing the sand nozzle. So as to complete the three functions of cleaning, dehydration and classification.

The cyclone of the desander is divided into two materials: one is high wear-resistant polyurethane material, and the other is high chromium cast iron material. The high chromium cast iron material is made of stainless steel inlet, outlet, and cone-shaped ceramic cyclone. , Conical stainless steel tank, automatic or manual sand discharge valve, recoil valve, etc. 

Its advantages are economical and practical, high temperature resistance, disadvantages are non-wearing, short service life, generally need to be replaced once in 2000 hours; polyurethane material It is composed of three parts: volute, cone and vertebral body. 

Its advantage is wear resistance, the service life can be as long as 4200 hours, the swirl effect is relatively good, but it is not resistant to high temperature.
