Stainless Steel Chemical Mixing Tank Selection Guide: Power Calculation Methods

Selecting the right stainless steel chemical mixing tank requires careful consideration of power requirements. There is no single universal formula for coating emulsification kettle power calculation due to system variations, but industry professionals commonly use empirical formulas with correction coefficients.
Basic Power Calculation Formula
Based on the dimensionless criterion method (Reynolds number Re, Power number Ne) combined with coating industry experience, the simplified formula is:
$$P = K \times V \times \mu^{0.5} \times \rho^{0.5} \times n^{1.8} \times F$$
Where: - K: Component coefficient (optimized through actual testing) - Standard dispersion disc: K = 0.0025-0.0035 - High-efficiency turbine dispersion disc: K = 0.0035-0.0055 - High-speed emulsifying head: K = 0.009-0.013 - V: Actual loading volume (L) = Nominal volume × Loading coefficient (0.7-0.8) - μ: Material operating viscosity (cP) - calculate using maximum viscosity during emulsification - ρ: Material density (g/cm³) - typically 1.1-1.5 for coatings, default 1.2 - n: Stirring/shearing component speed (rpm) - F: Intelligent compensation coefficient (default 1.1 for 10% safety margin)
Calculation Example
For a 1000L nominal capacity high solid content (55%) anti-corrosion paint: - Actual loading: 800L - Maximum viscosity: 8000 cP - Density: 1.3 g/cm³ - High-speed emulsifying head at 2800 rpm
Step-by-step calculation: - 8000^0.5 ≈ 89.4 - 1.3^0.5 ≈ 1.14 - 2800^1.8 ≈ 2,380,000
$$P ≈ 0.011 \times 800 \times 89.4 \times 1.14 \times 2.38 \times 1.1 ≈ 230kW$$
Quick Selection Table
For standard coating scenarios, you can directly match power based on "Volume + System Type":
| Volume | Low Viscosity | Medium Viscosity | High Viscosity | |--------|---------------|------------------|----------------| | 100L | 5.5-7.5 kW | 11-15 kW | 22-30 kW | | 500L | 15-22 kW | 37-45 kW | 75-90 kW | | 1000L | 30-45 kW | 75-90 kW | 150-200 kW |
