The fault shows that the correct value can be displayed after the calibration of weights, but the number does not return to zero after unloading, and the number of weights changes greatly after clearing, but the resistance value of sensors in concrete mixing station is in the normal range, and the instrument of concrete mixing station is no problem.
The reasons may be as follows: the angle iron of the fixed weighing frame for transportation has not been removed; the clip is issued at the pressure head and the pressure plate; the weighing body and the outside interferes with each other; the three sensor models do not match; and the partial load when weighing the material.
The methods to deal with the faults of concrete mixing station are as follows: if the angle iron of fixed scale frame is not removed for transportation, it should be removed in time; if the pressure head or the pressure plate is issued, it should be dealt with in time to make it smooth and without resistance; if the scale body interferes with the outside world, it should be isolated in time; if the three sensor types do not match, the sensor of the same type should be replaced; if the material is unbalanced, it should be adjusted.
When the contactor is sucked and the motor rotates clockwise, the outlet and outlet of the screw conveyor will not be discharged, and the air switch will trip after a little longer time; when the air switch is closed, the motor will still trip, and the phenomenon of no solidification of powder will be observed.
The reasons for the analysis may be: the mother machine is reversed; the air switch is damaged; the parent motor wiring may have a poor contact.
The method for handling the concrete mixing station is: if the mother machine is reversed, the motor of the mother machine can be adjusted by any two wires; if the air switch is damaged, it should be replaced; if the motor of the concrete mixing station has a bad contact, it should be checked.
