Concrete Mixing Plant Batching Machine Common Faults

The concrete batching machine serves as the second largest part of the mixing station, which plays an important role in the normal operation of the mixing station. Concrete batching machine in the operation if there is a problem, not timely solution, will directly affect the work of the entire concrete mixing plant.
Fault 1: automatic operation, the batching machine aggregate storage silo does not discharge material, the aggregate weighing indicator are zero.
Analysis of reasons: 1, aggregate weighing bucket unloading gate is not closed or not in place
Solution: If the solenoid valve is not changed, need to replace the solenoid valve. If the cylinder leaks, you need to consider repair or replace the cylinder.
2, the aggregate weighing bucket unloading door has been closed, but the cylinder magnetic switch has been bad can not be closed; magnetic switch is not in the correct position; magnetic switch to PLC line circuit or poor wiring.
Solution: Check the location of the magnetic switch and its wiring is correct.
Fault 2: Weighing machine weighing is not accurate
Analysis of the reasons: measurement scales are not allowed to check whether the stall is stuck, or other causes of scales can not move freely, if necessary, re-leveling.
Solution: After the ingredients show the weighing readings and set the material value of a great difference, should focus on checking some parameters such as the delay delay time is correct, the parameters inappropriate reference to the appearance value of the modified. It should also check whether the set material value is too small, in addition to check whether the storage storage capacity is stable, whether or not for a long time; check the material storage material is uniform, stone particle size can not be too much difference, sand thickness and dry Wet can not differ too much; after the replacement of the formula, whether the drop measurement, if not should be re-operation.
