Drilling fluid solids control system jet mixing device is the use of Venturi jet nozzle with a combination of original design of the new jet injection device, only simple in structure, and its highly feasible. SLH series of drilling solids control system jet mixing device is oil drilling solid control system supporting the use of a device, mainly used for configuration and increase the drilling fluid, changing the drilling fluid density, viscosity, water loss, etc., complete with shear pump using the effect is more prominent, by a sand pump and a jet mixing funnel connection with manifold valve mounted on a base consisting of safe and reliable performance, easy movement of, to meet the 1500 meters to 6,000 meters in solid control system The increased drilling and preparation.
