The role of twin-screw extruder in the field of production and manufacturing is becoming stronger and stronger, and it has gradually become an indispensable mechanical equipment for many manufacturers. We all know that the protection of machinery starts from installation, which is a continuous process. So how should the extruder be installed and debugged correctly so that there will be no mistakes, and how to maintain it later? TENGDA Plastic Extruder Machine Manufacturers organizes the following information, let's take a look.

1. How to debug the extruder correctly

1. First of all, let's talk about installation. Generally, the manufacturer will provide guidance, and it is enough to connect the wires in the correct way. The so-called debugging in this industry refers to whether the first startup meets the customer's needs (that is, the degree of debugging). A qualified extruder can be used normally after being connected to the power supply after leaving the factory, and no debugging is required.

2. The so-called debugging is nothing more than some problems that need to be solved in the follow-up, such as failure to meet customer requirements due to process problems during production (such as insufficient or too strong shear due to screw combination), and output failure to meet customer requirements.

3. Install the equipment in place: level, wiring, auxiliary equipment, etc.; check whether the wiring is correct; solve the corresponding problems after starting up (as above, the screw combination leads to unqualified materials, etc.).

2. How to maintain the screw extruder

1. Routine maintenance is a regular routine work, which does not take up the man-hours of equipment operation, and is usually completed during driving. The focus is to clean the machine, lubricate the moving parts, fasten the loose threaded parts, check and adjust the motor, control instruments, working parts and pipelines in time.

2. Periodic maintenance is generally performed after the extruder has been running continuously for 2500-5000 hours. The machine needs to be disassembled to check, measure, and identify the wear of the main parts, replace the parts that have reached the specified wear limit, and repair the damaged parts.

3. Empty operation is not allowed to prevent the screw and barrel from fluffing.

4. If abnormal sound occurs when the extruder is running, it should be stopped immediately for inspection or repair.

5. Prevent metal or other debris from falling into the hopper, so as not to damage the screw and barrel. In order to prevent iron debris from entering the barrel, a magnetic component or a magnetic frame can be installed at the feeding port of the barrel when the material enters the barrel. To prevent debris from falling into the barrel, the material must be screened in advance.

The above is what I have compiled for you about the installation and commissioning of the extruder and the post-stage maintenance. I hope it will be helpful to you.
