detail:
Plastic pipe production line failure: Pipe size tolerance:
Adjust the size of the vacuum can change the size of the park outside; adjust the traction speed can change the size of the park; correction sizing sleeve hole size;
Plastic pipe production line failure: pipe roundness tolerance
Adjust the vacuum setting machine, nozzle angle within the spray box, so that the pipe cooling uniformity; check the vacuum setting machine, the spray tank height of the water table, pressure gauge pressure, so that the spray volume is large and powerful; check the vacuum setting machine, spray box Water temperature conditions, if> 35 ℃, the need to configure the chilled water system or increase the cooling spray box; check the waterway, cleaning the filter; adjust the process; check and correct sizing bore hole garden; Ovality of pipe
Plastic pipe production line failure: pipe wall thickness is not uniform
Adjusting the wall thickness on the mold; adjusting the angle of the nozzle in the vacuum setting machine and the spray box so as to make the pipe cool uniformly; adjusting the outlet diameter of the calibrating sleeve so as to make the water evenly; disassembling the mold and checking whether the screws in the mold are loose and retightening;
Plastic pipe production line failure: plasticizing temperature is too high
Adjust the process; adjust the heating temperature of the mold core, and the interior of the mold ventilation cooling; screw shear heat is too high, replace the screw
