The shaftless trommel screen is composed of a motor, reducer, roller device, frame, sealing cover, and inlet and outlet.
The main steps of debugging work are:
1. Preparation before commissioning:
(1) After the parts are installed and passed the inspection, a trial run is required. Before the trial operation, check in detail whether the installation of parts meets the requirements of the drawings, whether the fasteners are firm, and whether there are obstacles around the screen body that hinder the operation;
(2) Put the rectangular inspection door in the open position, and rotate the screening drum by manual turning to observe whether the comb-type cleaning mechanism has jamming or friction. If there is, it can be adjusted by adjusting the bolt;
(3) Check that each bearing seat and gearbox should be well lubricated, and the gearbox oil level should be appropriate;
(4) The power connector should be firm and reliable, with good insulation and correct grounding.
2. No-load test run
(1) Jog the motor control button and check that the rotation of the motor should be consistent with the rotation shown on the cage shaftless trommel screen;
(2) Start the equipment to operate for 4-6 hours, observe the operation, if abnormal noise or other phenomena are found, stop the machine for inspection in time, find out the cause, and eliminate the fault. The following items should be checked after 4-6 hours of trial operation: the tightening of the fastening bolts everywhere, and if they are loose, they should be tightened in time.
3. Feeding
(1) When the sieving machine is in a stable state, start the feeding and discharging equipment, and carry out the feeding test; (2) Close the sealed isolation cover after normal discharge (in normal operation, the sealed isolation cover should always be in the closed position);
(3) Check the particle size of the discharged material and whether there is material leakage and dust;
(4) After running for half an hour, carefully check the parts and deal with the problems properly.
(5) The operation of the shaftless trommel screen should be checked frequently during the working process. If an abnormal operation or abnormal noise is found, the machine should be shut down for inspection in time to find out the cause and eliminate the fault.
