Preparatory work before commissioning: After the components of the trommel screen are installed and passed the inspection, the trial operation can be carried out. Before trial operation, Drum Screen check in detail that the components are installed correctly as shown in the drawings, the fasteners are firm, Drum Screen and whether there are obstacles around the screen body that hinder the operation of the drum screen; the rectangular inspection door is in the open position, Drum Screen and the screen is rotated by a manual crank Separate the cylinder and observe whether the comb-type cleaning mechanism has jamming or friction. If there is, it can be adjusted by adjusting the bolt; check that each bearing seat and gearbox should be well lubricated, Drum Screen and the gearbox oil level should be appropriate; the power connector should be firm and reliable, Drum Screen Good insulation and correct grounding.
No-load test run: jog the motor control button, Drum Screen check that the steering of the motor should be the same as that shown on the cage drum screen; Drum Screen start the equipment to run for 4-6 hours and observe the operation of the drum screen. If abnormal noise or other phenomena are found, stop it in time Check, Drum Screen find out the cause, and troubleshoot.
The following items should be checked during 4-6 hours of trial operation: The temperature of the main shaft bearing should not exceed 75℃ and the temperature rise should not exceed 45℃. The tightening of the tightening bolts everywhere, Drum Screen if found loose, should be tightened in time.
When the sieving machine is running smoothly, Drum Screen start the feeding and discharging equipment to conduct a feeding trial; close the sealed isolation cover after normal discharge (in normal operation, Drum Screen the sealed isolation cover should always be in the closed position); check the discharge particle size And whether there is material leakage and dust; Drum Screen run for half an hour, carefully check all parts, and deal with problems in time. During the working process, Drum Screen the operation should be checked frequently. If abnormal operation or abnormal sound is found, Drum Screen the machine should be shut down for inspection in time to find out the reason and eliminate the fault.
