How to operate an EPS pre-expander machine?
Even though a fine EPS pre-expander is automatic and reliable, there are still precautions that are needed to keep in mind. Firstly,in the case of a sudden power failure, the EPS pre-expander will automatically close the steam valve, open the material door and compressed the air valve to cool it, so that it can prevent the foam material in the barrel from condensing into agglomerates. If you want to discharge the raw materials in the barrel, you can use a blower or compressed air to blow out the foam material in the barrel, and then separate them according to the actual situation of the foam material. Secondly, when the machine needs to enter the barrel for maintenance, it is necessary to cut off the main power supply and set up a dedicated person to monitor it.After the maintenance is completed, please strictly check the remaining tools and parts in the barrel. Otherwise, the ventilation plate and rotating bracket at the bottom of the barrel will be damaged. Thirdly, in the production process of the machine, please strictly prevent the foreign matter mixed in the EPS material from entering the foaming barrel to avoid damaging the bottom ventilation plate. Fourthly, in the production process, the machine operator must pay attention to the sensitivity and reliability of the electric contact pressure gauge. If a problem is found, the electric contact pressure gauge must be repaired or replaced in time to ensure the normal and stable production of the machine. Last but not least, when inspecting and maintaining the machine, remember to turn off the power to avoid personal accidents.
