2. Details
    Mix head
    Mixing type
 
1) 2 components mixed by agitator
 
    Rotary valve with motor 1.5kw
    Ball valve, controlled pneumatically
 
2) Cleaning system
 
    Cleaning type: Clean by MC, residue are blown out by compressed air
    MC tank: 15L stainless steel tank
    Air cleaning, solvent cleaning are controlled by solenoid valve
    Visible leveler, safety valve, supercharging device
    Air exhausting is controlled manually.
    Cleaning pressure:0.15MPa
 
3) Metering unit
    Metering accuracy ±5‰
    Main parts
 
Variable frequency motor, coupling, positive displacement gear pump, safety valve, pressure sensor, speed sensor

 
4) Pressure control system
 
    Working pressure 0 - 4Mpa
    The alarm will be activated when pressure is over preset pressure threshold.
 
5) Flow rate testing
 
    The flow rate is controlled through VFD by changing flow rate of pump.
    The flow rate can be tested and calibrated manually.
 
6) Filtration
 
    Filter: screen filter
    Discharging: by discharging valve
