Applicability and StructureDrilling fluid jet mixer, an commonly used equipment in mixing fluid,is an important part of drilling fluid solid control system.When well blowout occurs,it can be used to mix large amount of weighted materials even in drilling fluid within little time.Structural sketch:1. Feeding hopper 2. Strainer 3. Butterfly valve 4. Jet pump assy. 5. BaseII. Working MechanismThe drilling fluid flow into the jet pump with certain pressure,in the jet pump fluid spouts out from jet nozzle first, then flows into shear pipe through mixing chamber. Materials will be added from hopper to mixing hopper, and move into shear pipe with the flow. During this process, they are dispersed and mixed. The mixture will enter into drilling fluid tank when flows out of the shear pipe.The shear pipe is hollow and it can expand gradually based on certain curved surface. It is mainly used to enlarge shearing force inside the pipe to disperse the material further and increase the mixture pressure head, this will make it easy to enter into circulating tank.Bernoulli effect is adopted in shear pipe which is flow rate is rapid with low pressure, and slow with high pressure. Pressure is low in the chamber when fluid spouts out in high speed from the jet nozzle; when fluid enters into the shear pipe, its section is enlarged and flow rate decreased so the pressure rises.III Main ParametersFluid mixing capacity: 200 m3/h Inlet pressure: 0.250.6MPaOutlet pressure: 0.10.3MPa Inlet and outlet size: 66Weight: 205kgSize: 1373mm750mm970mmIV Installation and Commissioning1. Connect the inlet opening of drilling fluid mixing jet mixer with the outlet pipe of sand pump, and the jopper outlet leads to drilling mud tank.2. 6flanges should be used at inlet and outlet.3. Base plate of the hopper should be fixed tightly.4. The hopper should not be equipped too high, since the more high, the less of mixing capacity.5. The sand pump used here should match with the mixing jet mixer.The following is the installation dwg.V MaintenanceThe necessary maintenance can improve the working reliability of the mixer,and can prolong its service life.1. daily maintenanceThe work is cleaning the feeding hopper and mixing chamber,keeping the equipment neat.2. Periodic maintenance（1）checking the fastenersChecking the fasteners once a month,be sure they are tightening.（2）unit anticorrosionPainting the paint breakage timely.郑州金时机械有限公司ZHENGZHOU JINSHI MACHINERY CO.,LTD诚信为本 技术为先Good faith-based Technology as first公司联系方式Company C
