Working principle of oil field drilling fluid horizontal decantercentrifuge

The oil field drilling fluid horizontal spiral centrifuge is a five stage solid particle control equipment in the drilling mud solid control system, which uses centrifugal settling separation

The principle is to separate the suspension in the drilling fluid. Drilling fluid centrifuge is mainly used for balancing the viscosity and specific gravity of drilling fluid, and recovering drilling fluid

The heavy metal powder in the well fluid saves drilling costs; Mainly separating solid particles of 2-5 μ m and 5-7 μ m in drilling fluid, it is petroleum

One of the important equipment in the field of drilling, coalbed methane drilling, and environmentally friendly waste mud treatment.

Working principle of oilfield drilling fluid centrifuge:

The drilling fluid centrifuge is driven by two motors. The main motor drives the drum and differential housing to rotate through a belt, while the auxiliary motor drives the screw after variable speed through the differential. This causes the drum to rotate in the same direction as the screw and has a certain differential speed. The principle of centrifugal settling is used to separate the drilling suspension. The suspension enters the drum through the discharge hole of the screw pusher from the feed pipe. Under the action of centrifugal force, solid particles are pushed towards the inner wall of the drum and discharged through the blades on the screw pusher to the slag discharge outlet at the small end of the drum. The liquid phase overflows through the overflow hole at the large end of the drum. Continuously cycling in this way to achieve the goal of continuous solid-liquid separation.
