Twin piston pouring machine

DVOJITY_stroj.jpgThe machine is intended for pouring PU compounds using two separately operated heads.

SA standard delivery consists of piston pumps with the dose extent 5 – 35 ml and with a fixed mixing ratio 100:25 (possibility of delivery with different parameters)

RThe machine frame is provided with traversing wheels and with adjusting screws. Component bins, dosing piston pumps, an electric switchboard and a revolving arm are located thereon. From the revolving arm, the material is fed through heated up hoses having the length of 5 m into the heads. The carrier of hoses and heads is not component part of the machine.

MANUAL OPERATION - The function of the heads is controlled from the switchboard panel
AUTOMATIC OPERATION - The function is controlled by means of external in and outlets.

Low-pressure mixing head

  • lightweight construction of duralumin
  • the mixing operation is ensured by a lamella agitator driven by a pneumatically operated motor
  • agitator revolutions metering by means of an induction scanner
  • inlet for liquid rinsing and for dry compressed air blowing through
  • two separately operated heads

Component dosing pumps

  • twin plunger pumps with pneumatic drive
  • one pump for each head
  • electronic metering of the stroke length
  • before entering the pump, the components are filtered
  • firmly set ratio (according to the pumps delivered)
  • checking of the pumps function through the components off-take on the pump outlet.

 

Control panel

  • control of the electric motor of the polyol bin agitator
  • switching on/off of the pneumatic motors of the mixing heads
  • control of spray-off, pouring, rinsing and blowing through for each head
  • switching over of automatic and manual machine operation
  • regulation and display of the hose temperature
  • display of the component levels height
  • LCD touch-sensitive display screen for setting, control and monitoring of the machine state

Touch-sensitive LCD colour display screen

DVOJITY_stitek

  • setting of the required pouring dose for each head (ml)
  • counters of operating hours
  • setting of speeds and times of the agitator runing cycling in the polyol bin
  • reporting „WASHING NEEDED“,when material remains for a longer time in the head than set
  • possibility of avoiding changes of important technological parameters using a password
  • operating reports (drop and minimum of levels, drop of compressed air...)
  • fault reports (fault of circuit breaker, converter...)
