Polyurethane foaming machine is a special equipment for polyurethane foam foaming. Polyurethane raw material performance indicators meet the requirements of the formulation of computer controller control, computer controller using today's advanced MCU unit embedded technology, with accurate measurement, simple operation, convenient maintenance, automatic alarm, prompt the last injection is finished, ready for the next injection and other functions.
1 to the polyurethane foaming machine cartridge for feeding, feeding do not add wrong, see clearly AB material;
2. Start the industrial chiller, set the required temperature, and control the material temperature to the appropriate position;
3. Close the feed valve, start the pressure valve of the nitrogen cylinder to charge and pressurize, and open the compressed air valve to reach a specific pressure.
4. Start the special main brake of polyurethane foaming machine and the POWER knob on the left side of the instrument panel, and the POWER SUPPLY indicator will turn green, then start the oil pressure system. When it is stable, press the low pressure cycle button to start the low pressure cycle.
5. Start the high pressure circulation, so that the black and white material circulation in the feed tank and the circulating water heat exchange in the industrial chiller, so that the material temperature of the black and white material reaches the set temperature requirements.
6. Set the feeding time on the dashboard and perform the feeding according to the corresponding requirements on the gun head.
7. After the production of polyurethane foaming machine is finished, close the nitrogen cylinder air valve and compressed air inlet valve, then stop the internal circulation of foaming machine, reset the power button on the left side and pull down the main brake to shut down the power supply.
