Repair And Troubleshooting of Concrete Mixing Plant

 Concrete mixing plant failure problems can be checked in accordance with the components step by step, can also be classified according to the nature of the fault, according to the nature of the failure we make analysis and propose solutions for reference.
 
1, the occurrence of high frequency fault
 
  Frequent high frequency, need to check the work of the regular inspection of such failures generally do not cause serious consequences can be adjusted at work at any time to solve. Such as conveyor belt deviation adjustment method should be analyzed and resolved from the principle, focusing on understanding the principle of three running three does not run (do not run before the run, do not run loose run, run high does not run low).
 
2, the occurrence of high frequency fault
 
  The occurrence frequency is lower than the previous species, but the maintenance of complex, usually caused by system failure or damage to parts, such as conveyor roller does not turn, the mixer spindle and the discharge port slurry leakage; such failures should be blender spindle seal Principle.
3, sudden failure
 
The frequency is very low, but improper handling or processing is not timely result in the consequences of National Chiao Tung University, can not be ignored, what will focus on description.
 
3.1 Aggregate silo doors can not be closed（www.zzxfjxwm.com）
 
Symptom: Aggregate said weighing value exceeds the value of a lot of formula, and the screen shows the silo has been cutting, even weighing the door open a long time there is still weighing value.
 
  Cause: (1) cylinder failure or damage; (2) control electromagnetic valve failure or damage; (3) a large aggregate or impurities will be stuck door; (4) control system failure.
 Solution: found the fault immediately shut down, manual operation will be stirring the concrete mixing after the release. Find the fault location and the cause, according to the cause of the fault or replace the damaged components, troubleshooting and then clean up the belt and overflow of aggregate.
 
3.2 aggregate measurement Doumen can not be closed
 
   Reason: (1) cylinder failure or damage (2) control solenoid valve failure or damage; (3) control system failure
 
Symptom: Aggregate scale began to measure after the screen shows a very low value, and in this value does not increase shaking, aggregate display in the next material.
 
Approach: with the aggregate warehouse door can not be closed the same.
 
3.3 Mixer failure
 
Causes and symptoms: (1) mixing blade fracture, spindle bearing damage and other parts of the spindle accidental damage, will be accompanied by the production of large abnormal sound, the host current will exceed the normal value.
(2) control component damage or control system failure, usually manifested as normal operation. (3) The discharge door can not be opened
 
Disposal: find the fault immediately shut down, manual operation mixer hydraulic door handle, the mixer all the materials drained, clean up the belt and the overflow of the aggregate, to find the fault location and the reasons for troubleshooting or replacement of damaged components.
