II.Product Introduction：

The drilling fluid desander produced by HONDIN is a secondary solid control device for drilling fluid solid phase control systems. The main working principle of the cyclone is centrifugal sedimentation. When the two-phase (or three-phase) mixed liquid to be separated enters the cyclone at a certain pressure from the feed port of the cyclone, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the different density of particles, the centrifugal force, centripetal buoyancy, fluid drag force and other sizes are different. Under the effect of centrifugal sedimentation, most of the coarse particles (or heavy phase) are discharged through the bottom flow of the cyclone, while most of the fine particles (or light phase) are discharged by the overflow pipe, so as to achieve the purpose of separation and classification. For efficient, high-volume processing of drilling fluids, multiple sets of cyclones can be installed to form a single, in-line desander. The 10 'or 12' inch cyclone is connected together through the common inlet and outlet pipeline, and the number of sand cyclone is 1-4. The drilling fluid desander separates particles in the 40-74 micron range from the mud.

The cyclone body is the main component of a 10 'or 12' cyclone, with the tip of the cone spiraling to the base of the vertebral body. The drip nozzle position is installed in the cone hole inside the compression cap. Press cap screw to cone tip. Turning the clamping cap clockwise compresses the drip nozzle, thereby reducing the opening of the drip nozzle. Turn the clamping cap counterclockwise to increase the opening, reduce the pressure on the drip nozzle, and the drip nozzle can be restored to the original size. The injection mode can be adjusted by the opening size of the drip nozzle during operation.

III.How it works:

A cyclone requires a steady feed pressure (head) and a steady feed speed (GPM). The feed pressure may be determined by the gravity feed system or the centrifugal pump installed in the drilling fluid recovery system. When the head (feed pressure), feed speed (GPM) and drip nozzle opening are matched, the cyclone can achieve the best use effect. An imbalance in any of these three variables will have a bad effect on the work of the cyclone. The pressure gauge installed on the drilling fluid desander is used to monitor the feed pressure. The mud enters the lower end line of the cyclone and then uniformly enters the inlet of the cyclone. The liquid discharged from the cyclone flows directly into the upper line of the desander, and the separated solid flows directly into the funnel installed at the lower end of the cyclone. The material removed from the funnel usually falls to the bottom flow screen of the drilling fluid desander.
