Modular production of spiral wound pipe machines can adapt to the special requirements of different users, shorten the development cycle of new products, and strive for a larger market share. The professionally produced spiral wound pipe machine can be extruded, and the equipped spiral wound pipe machine system modules are produced on a fixed point or even globally, which is very helpful to ensure the quality of the spiral wound HDPE pipe machine throughout the period, reduce costs, and speed up capital turnover. Next, let's take a look at the introduction of the spiral wound pipe machine. Here are some answers.
Here is the content list:
l What is the transmission part of the spiral wound pipe machine?
l Polymer materials control the wear and tear of spiral wound pipe machines.
l What is the working process of a spiral wound pipe machine?
The transmission part of a spiral wound pipe machine is usually composed of a motor, a reduction box, and a bearing. During the extrusion process, the screw speed must be stable and cannot change with the change of the screw load, to maintain the uniform quality of the products obtained. However, on different occasions, the screw must be variable to achieve the requirement that a spiral wound plastic pipe machine can extrude different plastics or different products. Therefore, this part generally uses AC commutator motors, DC motors, and other devices to achieve infinitely variable speed. Generally, the screw speed is 10 to 100 revolutions per minute.
Polymer material treatment HDPE spiral tank wear problem mainly refers to the inconsistent processing size of the spiral wound pipe machine feeding section bushing. When the spiral wound pipe machine bushing material is 38CrMoAlA, due to machining reasons (the positioning keyway and the mating part are not on the same axis), there will be a matching gap at the matching place with the side plate (material 40Cr or 45). When starting up and running, the rubber leaks due to the recoil of the rubber, and the temperature does not exceed 100°C. The company has used other products to repair it before, and it can only be used for 1 to 2 days. The use of polymer materials can solve the problem well.
The plastic material enters the spiral wound pipe machine from the hopper and is transported forward by the rotation of the screw. During the forward movement of the material, the material is heated by the barrel, and the shear and compression caused by the screw make the material melting, thus realizing the change between the three states of glass state, high elastic state, and viscous flow state. In the case of pressurization, the material in the viscous fluid state is passed through a die with a certain shape, and then becomes a continuum with a similar cross-section and the die according to the die, and then cooled and shaped to form a glass state. Parts to be processed.
