Hey there! As a supplier of PPR Pipe Making Machines, I often get asked about the technical parameters of these machines. Well, let's dive right in and break down what you need to know.
Extruder Parameters
The extruder is the heart of a PPR pipe making machine. First off, we've got the screw diameter. This is a crucial parameter as it determines the output capacity of the machine. A larger screw diameter generally means higher production rates. For instance, machines with a screw diameter of 65mm can produce around 100 - 150 kg per hour, while those with a 90mm screw diameter can churn out 200 - 300 kg per hour.
The screw speed is another important factor. It affects the melting and mixing of the PPR raw material. A variable screw speed allows for better control over the extrusion process. Most modern PPR pipe making machines have a screw speed range of 10 - 100 rpm. This flexibility enables operators to adjust the speed according to the specific requirements of the PPR material and the desired pipe specifications.
The power of the extruder motor is also significant. It needs to be sufficient to drive the screw and handle the pressure generated during the extrusion process. Motors typically range from 15kW to 75kW, depending on the size and output capacity of the machine.
Die Head Parameters
The die head is responsible for shaping the molten PPR material into the desired pipe shape. The die head diameter is designed to match the outer diameter of the PPR pipe being produced. Common die head diameters can range from 20mm to 200mm, covering a wide range of pipe sizes used in different applications, such as plumbing and irrigation.
The die head temperature is carefully controlled to ensure uniform melting and flow of the PPR material. Temperature controllers are used to maintain the die head temperature within a specific range, usually between 180°C and 220°C. This precise temperature control is essential for producing high - quality pipes with consistent wall thickness and smooth surfaces.
Cooling System Parameters
After the pipe is extruded from the die head, it needs to be cooled rapidly to solidify the shape. The cooling tank length is an important parameter. Longer cooling tanks provide more time for the pipe to cool down, resulting in better dimensional stability. Cooling tank lengths can vary from 3m to 12m, depending on the pipe diameter and production speed.
The water temperature in the cooling tank is also crucial. It is usually maintained between 15°C and 25°C. A proper water temperature ensures efficient cooling without causing excessive stress on the pipe, which could lead to cracking or deformation.
Vacuum Calibration Parameters
Vacuum calibration is used to ensure the accurate outer diameter and roundness of the PPR pipe. The vacuum degree in the calibration unit is typically set between - 0.06MPa and - 0.09MPa. This vacuum helps to hold the pipe against the calibration sleeve, resulting in a precise and uniform outer diameter.
The length of the vacuum calibration sleeve is designed to match the pipe diameter and production speed. It provides a stable environment for the pipe to cool and solidify while maintaining its shape.
Hauling Machine Parameters
The hauling machine is responsible for pulling the extruded and cooled PPR pipe forward at a constant speed. The hauling speed is adjustable and needs to be synchronized with the extrusion speed. A typical hauling speed range is 0.5 - 10 m/min. This allows for the production of pipes with different lengths and wall thicknesses.
The clamping force of the hauling machine is also important. It needs to be sufficient to grip the pipe firmly without causing damage. Most hauling machines use rubber belts or chains with adjustable clamping pressure to ensure a secure grip on the pipe.
Cutting Machine Parameters
The cutting machine is used to cut the continuous PPR pipe into the desired lengths. The cutting accuracy is a key parameter. Modern cutting machines can achieve a cutting accuracy of ± 1mm. This high level of accuracy ensures that the pipes meet the required length specifications.
The cutting speed is also significant. It should be fast enough to keep up with the production rate of the pipe making machine. Cutting speeds typically range from 1 - 10 cuts per minute, depending on the pipe diameter and the type of cutting mechanism used.
