Polyurethane foaming machine

Pu high pressure foaming machine with hydraulic pressure control, high pressure impinging mixture, a rate high, the gun head sel

Unit of measurement: measuring for components, including a cushion bracket, click, coupling, and a metering pump safety valve, electronic pressure switch

Polyether polyol and polyisocyanate component working pressure control in 6 ~ 22Mpa;

The limit pressure setting for 25Mpa. And the mechanical power protection;

The equipment measurement unit metering pump and motor with magnetic coupling, thus to prevent pump shaft leakage and prolonging the service life of the pump, and enhance the system's safety, reliability safety factor design; the service life is long;

Component filter:

Line gap type filter for installation in foam metering pump entrance filter device for filtering material, polyurethane composition.

Line gap filter cleaning cycle depends on the fractions of the impurity content, it is recommended that each before the start, for the filter cleaning, sewage.

High precision filter

High precision filter installed in the pressure pipeline, the main role is used to stabilize the system pressure.

There are two main types of flow control

Backflow test unit

Backflow test, hydraulic drive, electromagnetic valve control. With the handwheel adjustment of metering pump, 2 sets of testing unit for testing respectively; two component flow rate and mixing ratio.

2 you flow automatic control unit

You polyether polyol and polyisocyanate component flow using flow control. According to the pump output flow and component mixing ratio technology requirements, in the pouring process were set two component parameters associated with the metering pump; the adjusting hand wheel and the automatic test valve respectively for the two component flowmeter parameters calibration, component flow by frequency conversion governor or servo controller component flow automatic regulation and control.

The high-pressure mixing head is Pu high pressure foaming machine core component. For polyol and polyisocyanate components are fully mixed, has obtained the best foaming effect.

High pressure impingement mixing principle;

Hydraulic sequence control, self cleaning design;

Straight line type mixing head for non continuous sheet, pipe insulation foam

L type mixing head, adapt to a variety of hard foam, soft foam, semi-Yingpao, self-skinning foam system

Double mixing chamber L type mixing head adapted for Automotive dual hardness cushion foam

For the storage and control of polyether polyol, isocyanate and additional components.
