Failure analysis and solution of spiral wound pipe machine

A spiral wound pipe machine is a kind of common plastic machinery equipment. In the daily operation of the extruder, the spiral wound pipe machine will have various failures, which will affect the normal production of plastic machinery. Next, let's take a look at the common faults and solutions of spiral wound plastic pipe machines. Here are some answers.

The spiral wound pipe machine has methods to deal with abnormal noise.

If it happens in the reducer of the spiral wound pipe machine, it may be caused by bearing damage or poor lubrication, or it may be caused by gear wear, improper installation, and adjustment, or poor meshing. It is solved by commutation bearings, rising lubrication, commutation gears, or adjusting gear meshing conditions. If the noise is a sharp scraping sound, the position of the barrel of the spiral wound pipe machine should be deviated, causing the possibility of scraping the shaft head and the drive shaft sleeve. It can be solved by adjusting the barrel. If the barrel makes noise, it should be as a result of the screw being bent to brush the bore or the set temperature is simply too low, inflicting excessive friction of solid particles. It is processed by straightening the screw or increasing the set temperature.

The main reasons and solutions for spiral wound pipe machine wear and tear.

The main cause of spiral wound pipe machine wear.

The normal wear of the screw and barrel of the spiral wound pipe machine mainly occurs in the feeding area and the metering area. The main cause of wear is caused by the dry friction between the slice particles and the metal surface. When the slice heats up and softens, the wear decreases. Abnormal wear of the screw and barrel will occur when the screw is locked by ring knots and foreign objects. A ring knot means that the screw is locked by the condensed material. If the HDPE spiral tank lacks a good protection device, the powerful driving force may be twisted. If the screw is stuck, it will produce unusually huge resistance, causing serious damage to the surface of the screw and severe scratches on the barrel. The scratches on the barrel are difficult to repair. The barrel is meant to make sure that the service life is longer than that of the screw. For the normal wear and tear of the barrel, it is generally not repaired, and the method of repairing the screw thread is often used.

The solution to spiral-wound pipe machine screw wear.

The local damage of spiral wound pipe machine screw thread is repaired by surfacing welding of special anti-wear and corrosion-resistant alloy. Generally, chemical element protected fastening and plasma argon arc fastening square measure used. First, grind the outer surface of the worn screw to a depth of about 1.5 mm, then overlay the alloy layer to a sufficient size to ensure sufficient machining allowance, and finally grind the outer circle of the screw and the side of the thread to the outer dimension of the screw to the original size.
