What to do if the plastic pipe production equipment fails

Plastic pipe production equipment is an important part of chemical building materials. It has been widely recognized by users for its excellent performance, sanitation, environmental protection, and low energy consumption. Among them are UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes and polyethylene. Water supply pipe. The pipe assembly line is composed of control system, extruder, die head, forming cooling system, tractor, planetary cutter, turning frame, etc. Each pipe production line has two extruders, one mainly uses powerful conveying sleeves and high-efficiency screws, and the other is a small extruder for the extrusion line. A failure on the plastic pipe production line directly causes the pipe surface to be rough, there is a vibration ring inside, and there is no vacuum. Therefore, it is necessary to troubleshoot in time on the plastic pipe production line to improve product quality.

The failure of the plastic pipe production equipment directly causes the surface of the plastic pipe to be rough, there is a vibration ring inside, and there is no vacuum. Therefore, it is necessary to troubleshoot in time on the plastic pipe production line to improve product quality.

Failure of plastic pipe production equipment: The outer surface of the plastic pipe is uneven.

Adjust the process temperature; reduce the cooling water temperature, the better cooling water temperature of the PE pipe is 20~25℃; check whether the water channel is blocked or the water pressure is insufficient; check whether the heating ring such as the drum and the machine head are damaged; adjust the inlet flow rate of the sleeve; Please consult the raw material supplier for batch raw material parameters; check the core temperature of the chip. When the temperature of the die head part is exceeded, lower the die core temperature and clean the die head;

Failure of plastic pipe production equipment: There are groove marks on the outer surface of the plastic pipe.

Adjust the outlet pressure of the shaped sleeve to balance the water volume at the outlet of the shaped sleeve; adjust the nozzle angle of the vacuum shaped sleeve to make the tube cool evenly; check the mold, the sizing sleeve, the cutting machine and other hardware debris and burrs.

Failure of plastic pipe production equipment: There are dents on the inner wall.

Check whether the inner cylinder is full of water, if so, clamp the tube blank just out of the mold tightly to seal the inner cylinder; reduce the temperature of the inner cylinder; clean and polish the mold;

Failure of plastic pipe production equipment: the inner ring of the pipe jitters.

Adjust the water output of the shaped sleeve to make the water output uniform; adjust the vacuum degree of the two chambers so that the vacuum degree of the rear chamber is slightly higher than that of the front chamber; check whether the vacuum pad is too tight; check whether the tractor shakes; check the discharge of the main engine Whether it is uniform

Failure of plastic pipe production equipment: no vacuum state.

Make sure that the water inlet of the vacuum pump is blocked. If it is blocked, use a needle to clear it. Check whether the vacuum pump is working properly; check whether the vacuum pipeline is leaking; check whether the small hole in the middle of the pressure core needle is blocked, if it is blocked, use a thin iron wire to clear it;

Failure of plastic pipe production equipment: outer diameter is out of tolerance;

The size of the outer circle can be changed by adjusting the vacuum degree. Adjust the traction force to change the size of the outer circle; adjust the size of the inner hole of the sizing sleeve;

Failure of plastic pipe production equipment: the pipe circle is too large;

Adjust the angle of the nozzle in the vacuum setting machine and the spray box to make the pipe cool evenly; check the water level in the vacuum setting machine and the spray box and the pressure of the water pressure gauge to increase the spray volume and force; check the vacuum setting machine and The water temperature in the spray box. When the temperature exceeds 35°C, a cooling system should be installed or a spray cooling box should be added. Check the water course and clean the filter. Adjustment flow chart; check and correct the radius of the inner hole of the sizing sleeve; adjust the catheter clamping device to correct the ellipticity of the catheter;

Failure of plastic pipe production equipment: uneven pipe wall thickness;

Adjust the wall thickness of the mold; adjust the angle of the nozzle in the vacuum setting machine and the spray cylinder to make the pipe cool evenly; adjust the water output of the setting sleeve to make the water even; remove the mold wall, check whether the mold wall screws are loose, and then tighten it again.
