What are the production equipment for PE pipes? The production equipment for PE pipes has the following:
1. Extruder
The diameter of the screw is 55 to 200mm, and the ratio of length to diameter is 20:1, 25:1, 30:1, 32:1, 33:1, 34:1, the compression ratio is 3~4, and the screw is a separate screw.
2. The vacuum setting box and the cooling water tank
The vacuum setting box consists of a box, a sprinkler, a pump, a vacuum pump, a fixed diameter sleeve and so on. The principle of vacuum setting is the use of the vacuum pump to draw the air inside the box, the box body forms negative pressure, the effect of atmospheric pressure into the blank tube and core in the inner wall of the round, the billet to sleeve cooling rapidly through the frozen water, so as to achieve the set size effect.
3. Traction machine
The principle of traction machine is composed of cylinder rubber crawler pressed on the pipe surface, the friction force is increased, the transmission system will pass pipes from the vacuum box pull speed. The tractor has 2 grasping and 3 grasping. The larger the pipe production is, the more you need to catch, the greater the cylinder force is.
4. Cutting machine
The cutting machine is the planet cutting machine, the cutting way is the non chip cutting. The way to carry the knife can be divided into hydraulic feed type.
No cutting machine: the end face is cut and smooth, but the large pipe and thick wall pipe can not be cut.
Hydraulic feed type: the feed is elastic, but the material is polluted when the oil is leaking.
5, auxiliary machine (feeding machine)
The feeding machine is a vacuum feeder. The structure of the vacuum feeder is complex and the failure rate is high. The principle is: the small hopper circulating pump air, negative pressure is formed, so that the big pressure suction tube around the particle through a suction pipe is pressed into the small hopper, the hopper is small when the fill material, circulating pump stops working, the small hopper material by gravity free fall into the hopper in the the beginning of the second, suction.
