The test run of the machine must be operated by a person who is familiar with the process, so that measures can be taken when an accident occurs during the test run to prevent the accident. Check whether the No. 46 gear oil in the reduction gearbox and distribution gearbox reaches the oil mark. If not, the oil should be added to the oil mark. Start the main motor and check to see if its steering is correct. Please note that if the steering does not correspond, the car will be shut down immediately. The screw must rotate outward.
Also note that the machine should avoid running under no load as much as possible to prevent the screw and barrel from being scratched or the screw biting. For example, if the vehicle is run empty, lubricating oil should be added to the barrel. Check the rotation direction of the exhaust motor, vacuum pump and all fans.
Turn on the cooling device, let in the cooling water, check whether the pipeline is smooth, and there is no leakage. After all the above tests are normal, you can turn on the heating switch to check whether the heating and cooling are normal.
Observe the temperature. When the temperature in each heating zone reaches the required value, start the host after 30 minutes of heat preservation and start feeding. Slowly until the die mouth is discharged, then gradually accelerate to the speed required by the process, and then adjust Feed the screw speed, and start the vacuum pump to exhaust, at this time, check whether the quality of the extruded product (including plasticization quality, appearance quality, and internal quality) meets the standard.
