1 after the commissioning of the mixer, the load test run. When the load is running, each device needs to run continuously with no less than 20 pieces of material.
2: mixer load test run, the speed should be carried out from low to high speed, and try the soft material after the test hard material.
3: mixer load test run, the amount of glue from the working volume of 50%, 75% gradually increased to full load.
4: the mixer should have the lubrication oil pump can be started before the start of the main motor of the chain device, at the same time the air to the rear of the 10- 15min can load the load test run.
5: the last car after the end of the rubber, air to 15-20min and then stop. Air transfer, the end face seal lubrication system to continue to seal the sealing surface of the seal, the role of lubrication.
6: the end of the mixer rotor seal without leakage, no leakage of powder, to allow a rubber, oil and powder mixture paste leakage.
7: discharge door should be well sealed, no leakage.
8: mixer electrical, hydraulic control system should be flexible, safe and reliable.
9: the temperature control system can meet the requirements of the mixing process, the temperature should be within the allowable range of process conditions.
After passing through the load test operation confirmed that there is no abnormal phenomenon, after the consent of the parties concerned, can be transferred to production.
