SD static mixer

詳細(xì)介紹

Product Features SD type static mixer can be used to disperse droplets to 10μm during the emulsification process. It is used for general mixing process unevenness coefficient: a√x≤1~5% SD type calculation formula △P=(f*ρc/2)*W2*L/D Re=dh*ρc*w/μ W=(Q/πD2*900) 1Kg(f)/cm2=98100N/m2 △P resistance drop (N/m2) f friction coefficient (no dimension) ρc fluid density (Kg/m3) W fluid line speed (m/s) L mixer length (mm) dh hydraulic diameter (mm) ε void ratio (without dimension) μ fluid viscosity (CP) A total area of mixing unit (mm2) δ unit material thickness (mm) D pipe inner diameter (mm) Re Reynolds number (without dimension) Table of relationship between SD Reynolds number Re and friction coefficient f Pressure drop calculation example Assumption: Fluid flow rate Q=140m3/h Fluid density ρc=800Kg/m3 Viscosity μ=28CP Pipe inner diameter D=200mm Length L=2000mm Hydraulic diameter dh=100m W=Q/900πD2=140/900*3.14*0.22=1.24m/s Re=dh*ρc*w/μ=100*800*1.24/28=3538 Check the table to get Re>150, f=1 △P=(f*ρc/2)*L/D=(2.53*800*1.242/2)*2000/200=15560.5N/m2=0.16Kg(f)/cm2 SD type product use Suitable for mixing, reaction, absorption, injection molding, color matching, heat transfer and other processes in the chemical, petroleum, pharmaceutical, food, fine chemical, plastic, environmental, synthetic fiber, metallurgical and other sectors, for large, medium and small flow with impurities or viscosity Highly viscous media of ≤ 106 centipoise is especially suitable. SD type product specification model table Description: 1. The nominal pressure is determined according to the user's process conditions. 2, material: stainless steel, carbon steel, titanium, PTFE, polypropylene, etc. 3, flange standard: match the user connection piece, can provide matching flange 4, the mixing unit can be designed to be made of pumpable or fixed 5, hourly flow is based on water
