How to maintain the granulator?

　Twin screw plastic granulator means that there are two screws meshing in the barrel of the granulator to jointly complete the pushing conveying and plasticizing work before the forced calling of plastic. It is mainly used for filling, blending, modifying, adding, chlorinating, polypropylene and super absorbent resin processing of rubber plastic and engineering resin.

How to maintain the twin screw plastic granulator? In order to better extend its service life and work efficiency.

Daily maintenance

As the electrical control system has high requirements for environmental temperature and dust prevention, the electrical system should be separated from the production site, and ventilation or ventilator should be installed. It is suggested that the electric control cabinet should be placed in a simple room to keep the room clean and ventilated, so that the indoor temperature is not higher than 40 ℃.

The extruder is not allowed to run empty for a long time to avoid roughening of screw and barrel. When the main engine starts idling, it is not allowed to exceed 100r / min; when starting the main engine, slow down first, check whether there is abnormal sound after starting the main engine, and then slowly increase the speed of the main engine to the allowable range of the process. When the new machine is running in, the current load should be 60-70%, and the current in normal use should not exceed 90%. Note: in case of abnormal sound during the operation of extruder, stop the machine immediately and open the barrel for inspection or repair

The oil pump shall be turned on before starting the machine and turned off after shutting down; the water pump shall be kept in working condition during the whole production process, and the operation of the water pump shall not be stopped, so as to avoid the decomposition and carbonization of materials in the barrel due to the rise of barrel temperature; the asbestos hood of the main motor fan shall be cleaned frequently, so as to avoid too much dust sticking to block the hood, resulting in insufficient heat dissipation of the motor and tripping due to overheating.

Clean the dirt, tools and sundries on the surface of the unit in time.

Strictly prevent metal or other sundries from falling into the hopper, so as not to damage the screw and barrel. In order to prevent iron impurities from entering the barrel, magnetic absorbing parts or magnetic frame can be installed at the feeding port of the barrel to prevent impurities from falling into the barrel. The materials should be screened in advance.

Pay attention to the clean production environment, do not make the waste 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 height. If the oil level is too low, the lubrication is not enough, and the service life of the parts will be reduced. If the oil level is too high, the heating is too high, the energy consumption is too high, and the oil is easy to deteriorate, the lubrication will also fail, causing damage to the parts. The sealing gasket (ring) should be replaced in time at the oil leakage part of the reducer to ensure the amount of lubricating oil.
