2.7   Metering unit: Measurement accuracy≤0.5%

All the parts such as Shift motor、Gear metering pump、Bracket、Coupling is using to metering the components’ flowout.

2.8 Working pressure limit and control system

Both polyol and isocyanate side working pressure are allowed in a range of 6~22Mpa. Whenever the working pressure exceeds the range, the pouring operation will be stopped automatically and an alarm message of < working pressure abnormality > will be displaying on control panel at the same time.

The limit pressure of the metering pump is pre-settled as 25Mpa and with mechanical & electrical safety protection:

--- Mechanical protection: the relief valve function open whenever pressure reach 25Mpa,

--- Electrical protection: the metering unit emergency stop, audio alarm, and a message of <pump over pressure> display on panel screen.

The POLY. metering pump inlet pressure protection is pre-settled as 0.25Mpa, and the ISO. metering pump inlet pressure protection is pre-settled as 0.15Mpa. Whenever the inlet pressure lower than the preset value, the metering unit emergency stop, audio alarm, and a message of <pump pre-pressure too low> display on panel screen.
