Good polyurethane foaming machine
quality can bring high efficiency to consumers, but the operation method is also very important. If operating errors often bring serious results, then what points should be paid attention to when operating polyurethane foaming machine?
1. Before consumption of polyurethane foaming machine, check the wiring condition of all components. After the host is powered, turn off the power of the air compressor and chiller at the same time.
2. The metering pump before operation must go to the tank, feed, seal, open the pressure valve, and fill the tank with pressure.
3. Open the discharge valve at the bottom of the sewage tank, and after filling the metering pump, open the metering pump exhaust valve to evacuate the air to the discharge valve.
4. When the material pipeline is assembled and disassembled, the main power supply should be turned off, and the drain valve on the cylinder should be opened. The drain valve at the bottom of the material cylinder should be closed, and the disassembly should be stopped after confirming the error.
5. When the temperature of the polyurethane foaming machine mold is too low, the foaming system has poor activity, long curing time, incomplete response and cavitation, and the temperature of the foaming mold and the ambient temperature of the foaming furnace must be strictly controlled.
6. Especially in winter, it must be foamed in a polyurethane foaming machine and preheated in a preheating furnace for more than 30 minutes. After foaming for a period of time in the summer, the foam system should be cooled and cooled.
