subject: Plastic Pipe Production Line Fault And The Treatment Method [print this page] The plastic pipe extrusion machine malfunction, which will result in the plastic pipe material surface coarse, internal appear jitter ring, no vacuum wait for a phenomenon, so to promptly eliminate plastic pipe production line fault, can improve the quality of products.
The plastic pipe material surface roughness: adjusting processing temperature; Reduce water cooling, PE pipe optimum cooling water temperature of 20 ~ 25 ; Check the waterway, and whether there are insufficient blocked or water pressure; Check the barrel, head, there is no damage to the heating circle; Adjustment of sizing water flow; Consulting raw material suppliers, this batch raw material parameters; Check the mould core temperature, if higher than the mouth mode section temperature, the lower the core temperature; Clean up the mould.
Plastic pipe material outside surface appear ditch mark: adjusting the sizing set of water pressure, water yield requirements equilibrium; Adjust the vacuum calibrating the nozzle Angle, make the pipe cooling uniform; Check the mouth mold, bearing sets, cutting machine and other hardware whether there is sundry, burr, etc.
Plastic pipe material inside surface appear ditch mark: check whether tube water, such as feed water will just export die of tube embryos knead firm, make them closed cavity; Reduce the internal temperature of the mould; The cleaning and polishing mold.
Plastic pipe material pipe internal appear jitter ring: adjusting the sizing set out of the water, the water uniform; Adjust the vacuum, vacuum after slightly higher than the vacuum before; Check vacuum gasket is too tight; Check the drawer ever exist jitter phenomenon; Check whether the material host uniform.
Plastic tubing no vacuum, vacuum pump inlet check whether jams, such as congestion, dredge with needle thing; Check vacuum pump is functioning properly; Check the vacuum tube road ever leak; Check the core moulding screw holes in the middle of the tight for blockage, such as congestion, with fine wire dredge.
Plastic pipe outer size outoftolerance: adjusting the vacuum degree can change the size of the size; Adjust the traction speed can be changed the garden size; Fixed bearing set inside hole size.
