The concrete mixer batching system is linked with the heavy load test procedure. The interlocking test of all batching systems can be combined with the concrete mixer heavy load test. When all the ingredients are linked, the batching and discharging cycle of each tray should be 3540 seconds.
The rapping motor cannot be started. Productive test: According to the microcomputer operation manual, after each tank of material is sent, it is shaken for 10 seconds with a rapping motor. When the wind is sent. Enter the recipe and the task list for a productive heavy load test. Check that the system compressed air pressure is normal. Open each gate and valve. Start the mixer and belt conveyor. The microcomputer cuts into the production state for the ingredients. Manual operation can be performed first, and then automatic production is carried out in units of a mixer truck. Record actual ingredient time and check productivity. Check each print record, the ingredient pass rate should be above 90%, in the mixer car. The manual butterfly valve of the cement can adjust the opening according to the batching time. In the continuous batching and weighing test, the selected weighing advance amount should be adjusted and recorded to ensure the batching accuracy is achieved in a short time.
First start the thick oil pump to fill the mixer bearing, the mixer idle test: confirm that there is no foreign matter in the twin-shaft mixer.
Restart the mixer motor for 30 minutes, confirm that the operation is normal, the gap between the blade and the mixing drum wall is adjusted to <3mm. See the mixer instruction manual. Check that there is no foreign matter in the screw conveyor, start the screw conveyor one by one, and run for 15 minutes without abnormality.
Start the concrete mixming plant belt conveyor. When the feeder starts running, the tape should not be deflected. If there is a deviation, the tail tension bolt and the centering roller can be adjusted. There was no abnormality after 15 minutes of operation.
No-load linkage test: The microcomputer manually and automatically performs the no-load linkage test of the mixing station system to verify whether the equipment startup sequence is correct and whether the equipment and mechanism are operating normally. After the adjustment is completed, all machines should be subjected to an 8-hour no-load linkage running test.
