1. Connect the power switch, the power indicator does not light up
Open the back cover of the chassis and check whether the main system fuse is blown.
2. The foaming is crisp and the color is dark
1)Check the white material side filter screen, the white material hole of the gun nozzle, whether the oblique hole is blocked, whether the filter screen at the bottom of the white material pump is blocked, and clean it if there is.
2)PAppropriately increase the temperature or pressure of the white material. (It can be simply summarized as: too much black material)
3)The ejection state is not ideal:
Reasons for temperature: If the temperature is too high, the foaming agent in the polyol will vaporize, which will cause the raw materials to have a fluffy effect, causing the raw materials to fly too much; if the temperature is too low, it will produce wispy effects. The two kinds of raw materials are not uniformly mixed, resulting in waste, resulting in low foaming ratio and poor insulation effect of the product.
Causes of pressure: Too high pressure of the polyurethane foaming machine will cause serious splashing and rebound of sprayed raw materials or excessive scattering; too low pressure will cause uneven mixing of raw materials.
4. The A or B pump jumps quickly, and the nozzle discharge is reduced or
1)Immediately stop the machine and check whether the black or white material barrels are empty. If so, replace the materials and drain the air in the feeding pipe to be energized. Otherwise, the empty material pipe will easily burn the heating line!
2)Check whether the pump head and the air nail joint are loose.
5. The foaming of the polyurethane foaming machine is white and soft and debonding
1)Check the black material side filter screen, gun nozzle material hole, oblique hole is blocked, if there is, clean it up.
2)Properly increase the temperature and pressure of the black material. When the air pressure is close to the starting pressure of the air compressor, it is slow, and the foam shrinkage should appropriately reduce the white material pressure. (It can be simply summarized as: too much white material)
