The black and yellow jacket sheathed tube vacuum sizing method production line is a new type of anticorrosive and heat preservation pipe production line supporting equipment developed by our company based on the domestic market requirements and digestion and absorption of German technology. It has high automation, fast cooling speed, high output, and performance. Stability, long service life and other characteristics, especially compared with the pipe produced by the positive pressure (inner inflation) method, whether in terms of ring steel or bearing pressure, the performance indicators are far more than 1/3, which is currently the international The most advanced and popular large-scale anti-corrosion insulation pipe production line. This product solves the disadvantages of the original inner aeration equipment, such as high danger, uneven wall thickness, and difficult air sealing. It doubles the output and becomes one of the most advanced insulation pipe equipment in China. The entire vacuum system is stable and adjustable, which greatly improves the output and quality of the product.

1. The production line is composed of an extruder, a mold, a sizing sleeve, a vacuum sizing box, a tractor, a planetary cutting machine, a managed sports car and an electrical control system.

2. Features of the unit:

2.1 Adopting frequency conversion or DC speed-regulating motor (for users to choose), energy saving, power saving, low control power, low noise, high speed, greatly increase the degree of mechanization and production efficiency.

2.2 The ZLYJ series hard tooth surface reducer is adopted, which has the characteristics of small size, large torque, high load carrying capacity, stable transmission, low noise, high efficiency and long service life.

2.3 The main machine adopts BM separation type high-speed extrusion screw, which is made of high-quality alloy steel 38CrMoAlA, with surface nitriding treatment, which is resistant to wear, corrosion, high strength and good plasticizing effect.

2.4 It is equipped with PLC intelligent control. The industrial-level human-machine interface replaces the functions of the traditional control panel. Using the human-machine interface can save PLC I / 0 templates, button switches, digital settings, indicators, etc., and can display a variety of important information at any time, which is beneficial to operators Correctly grasp the operation of the machine to avoid errors and facilitate maintenance. When operating, just press the control element on the touch screen to operate the machine. The screen of the touch screen can be designed and planned according to the actual needs of the site, which is easy to operate without causing misoperation. The program can be changed at any time, even after production, the program can be changed according to the problems found, and the hardware does not need to be changed.
