Since the electrical control system has high requirements for ambient temperature and dust prevention, the electrical system should be isolated from the production site, and ventilation or ventilation fans should be installed. It is recommended to place the electric control cabinet in a simple room to keep the room clean and ventilated. Make the indoor temperature not higher than 40 °C.
The extruder does not allow empty cars to run, so as to avoid screwing and machine rolling. When the host starts idling, it is not allowed to exceed 100r/min; when starting the host, the speed is low first. After starting the host, check whether there is abnormal noise and then slowly increase the host speed to within the allowable range of the process (it can be adjusted to the best state). When the new machine is running in, the current load should be 60-70%, and the current during normal use should preferably not exceed 90%. Note: If an abnormal sound occurs while the extruder is running, stop it immediately for inspection or repair.
Turn on the oil pump first, turn off the oil pump after shutting down; the water pump keeps working state during the whole production process, can not stop the operation of the water pump, so as to avoid the carbonization of the material in the barrel caused by the temperature rise of the barrel; the asbestos hood of the main motor fan needs to be cleaned frequently To avoid excessive dust adhesion, block the hood, and the motor does not heat enough to trip due to overheating.
Clean the dirt, tools and debris on the surface of the unit in time.
Prevent metal or other debris from falling into the hopper to avoid damage to the screw and barrel. In order to prevent iron debris from entering the barrel, a magnetically absorbing part or a magnetic frame may be placed at the feeding port of the material to prevent the impurities from falling into the material.
Pay attention to the clean production environment, do not let the garbage impurities mixed into the material to block the filter plate, affect the product output, quality and increase the resistance of the machine head.
The gearbox should use the lubricating oil specified in the machine manual, and add the oil according to the specified oil level. The oil is too small, the lubrication is not enough, and the service life of the parts is reduced. The oil is too much, the heat is large, the energy consumption is high, and the oil is easy to deteriorate. Also, the lubrication is invalidated, resulting in damage to the parts. The oil leakage part of the gearbox should be replaced in time to ensure the amount of lubricant.
