When it comes to the manufacturing of jacket pipes, a Jacket Pipe Extrusion Machine plays a pivotal role. As a leading supplier of these machines, we understand the significance of technical parameters in ensuring optimal performance and high - quality product output. In this blog, we will delve into the key technical parameters of a Jacket Pipe Extrusion Machine.
Screw Diameter and L/D Ratio
The screw is one of the most crucial components in a Jacket Pipe Extrusion Machine. The screw diameter is an important parameter that directly affects the production capacity of the machine. A larger screw diameter generally allows for a higher throughput of the raw material. For example, our machines offer a range of screw diameters, from 65mm to 150mm, allowing customers to choose according to their specific production requirements.
The L/D ratio (length - to - diameter ratio) of the screw is equally important. It reflects the length of the screw relative to its diameter. A higher L/D ratio means that the raw material has more time and space to be plasticized and homogenized in the screw barrel. This results in better mixing of the polymer and additives, and a more uniform melt. In our Jacket Pipe Extrusion Machines, the L/D ratio typically ranges from 28:1 to 36:1, which ensures excellent plasticizing effect and high - quality pipe production.
Extrusion Capacity
Extrusion capacity refers to the amount of material that the extrusion machine can process per unit of time. It is usually measured in kilograms per hour (kg/h). The extrusion capacity is influenced by factors such as screw diameter, rotation speed, and the type of raw material. Our machines are designed to have adjustable extrusion capacities. For smaller - scale production, we can offer machines with an extrusion capacity of around 100 - 200 kg/h. For large - scale industrial production, we have machines capable of reaching an extrusion capacity of up to 1000 kg/h or more. This flexibility allows our customers in different industries to find a suitable machine for their production needs.
Motor Power
The motor power of a Jacket Pipe Extrusion Machine is directly related to its extrusion capacity and the resistance it needs to overcome during the extrusion process. A higher - power motor can provide more torque, enabling the screw to rotate smoothly and extrude the material efficiently. We carefully select the motor power for each of our machines based on the screw diameter and the expected extrusion capacity. For small - sized screw diameters, a motor with a power of around 18.5 - 37 kW may be sufficient. However, for larger screw diameters and higher extrusion capacities, we use motors with powers up to 132 kW or more. This ensures the stable operation of the machine and consistent product quality.
Die Head Structure and Size
The die head is responsible for shaping the molten plastic into the desired jacket pipe shape. The structure of the die head can vary depending on the type of pipe being produced. Our die heads are specifically designed for jacket pipe production, with features such as uniform melt flow distribution and precise temperature control.
The size of the die head determines the outer diameter of the jacket pipe. We can customize the die head size according to the customer's requirements. For example, if a customer needs to produce jacket pipes with an outer diameter ranging from 20mm to 1200mm, we can provide a corresponding die head. This customization ability allows us to meet the diverse needs of our customers in different applications, such as PE Heat Insulation Pipe Extrusion Line.
Cooling System
A proper cooling system is essential for a Jacket Pipe Extrusion Machine. After the molten plastic is extruded through the die head, it needs to be cooled rapidly to solidify and maintain its shape. Our cooling systems are designed to provide efficient and uniform cooling.
We usually use a combination of water cooling and air cooling. The water cooling system can quickly remove a large amount of heat, while the air cooling system helps to further cool the surface of the pipe and prevent surface defects. The cooling rate can be adjusted according to the pipe diameter, wall thickness, and the type of raw material. This ensures that the jacket pipes have good mechanical properties and dimensional stability.
Control System
The control system of a Jacket Pipe Extrusion Machine is the brain of the whole operation. It allows operators to monitor and adjust various parameters, such as screw rotation speed, temperature, and extrusion pressure. Our machines are equipped with advanced control systems that use programmable logic controllers (PLCs) and touch - screen interfaces.
The PLC can precisely control the operation of all components of the machine, ensuring stable and accurate production. The touch - screen interface provides a user - friendly way for operators to set parameters, view production data, and diagnose faults. With remote monitoring capabilities, we can also provide timely technical support to our customers, even if they are far away.
Traction and Cutting System
The traction system is used to pull the extruded jacket pipe at a constant speed. It ensures that the pipe has a uniform wall thickness and length. Our traction systems are designed with adjustable traction force and speed, which can be adapted to different pipe diameters and materials.
The cutting system is responsible for cutting the continuous extruded pipe into the desired lengths. We use high - precision cutting devices that can make clean and accurate cuts. The cutting length can be easily set on the control panel. This ensures that the final product meets the customer's dimensional requirements, whether it is for Jacket Pipes Production Line or Pre-insulated HDPE Jacket Pipes Production Line.
