About routine maintenance of the extruder
The working mechanism of the screw extruder relies on the pressure and shear force generated by the rotation of the screw, so that the material can be fully plasticized and uniformly mixed, and formed by die molding. This type of equipment needs regular maintenance during use, mainly including the following aspects:
No debris is allowed in the material. Hard materials such as metal and sand are strictly prohibited from entering the hopper and extruder.
When opening the cartridge cover or the exhaust cap, prevent foreign objects from falling into the main unit.
To have enough warm-up time, the manual drive should be brisk before driving. Generally, it should be kept at a constant temperature for 2 hours after reaching the process set temperature.
The screw is only allowed to start at low speeds and the idle time is no more than 3 minutes.
After the machine has been in use for a period of time, do a thorough inspection to check the tightness of all the screws.
In the event of production interruption, the main drive and heating are stopped. When the power supply is restored, the barrels must be reheated to the specified temperature and held for a period of time before the extruder can be started.
After 500 hours of use in the screw extruder, there will be iron scraps or other impurities from the gears in the gearbox. Therefore, the gears should be cleaned and the gearbox oil should be replaced. If the steering fullness of the meter and the pointer is found, check whether the contact of the edge such as the thermocouple is good.
Reasonable use, coupled with improved maintenance in the later period, can ensure the normal operation of the equipment and the extension of the service life.Single Screw Machine manufacturers
