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.
