Concrete mixer truck drivers have encountered unexpected situations in their daily work, which makes people worried. They can't watch the concrete solidify in the tank. Here Lily mixer gives you some emergency treatment methods:
1、 First understand the working principle of mixer tank: engine power take-off - hydraulic pump - hydraulic motor - reducer - tank
2、 Fault analysis
Check whether the engine works normally
Check if there is any problem in the hydraulic system of the upper part.
3、 Looking for faults: stop the engine in time in case of faults, listen to whether there is abnormal noise in all parts of the engine reducer, check whether the oil level in the radiator and reducer is normal, and pull the control lever to see whether the forward and reverse rotation do not turn.
4、 Emergency treatment
When there is no problem with the motor and reducer, connect the emergency oil pipe to the rescue vehicle to release the concrete.
In case of reducer or motor failure, the emergency hole on the tank should be opened to ensure that the emergency hole is super low and a large amount of water washes the inside of the tank to prevent solidification.
In daily use, the concrete mixer should pay attention to maintenance, and often check whether the gear oil is enough. If abnormal noise is found in the reducer, the treatment method is as follows:
If abnormal response of reducer is found during use, the following inspection shall be conducted:
Check whether the gear oil in the reducer is enough, release a small amount of gear oil to see whether it is blackened and deteriorated, and check whether the reducer is impacted by external force
If it is found that there are many iron chips in the oil, it is certain that the internal gear of the reducer has been damaged and worn out. In this case, the reducer should be replaced immediately.
Abnormal noise in case of heavy vehicle disaster: check whether the flange screw on the reducer is loose, and tighten the screw in time.
Buzzing noise of reducer: check whether the oil in the reducer is deteriorated or impurity. If there is no abnormal condition of gear oil, it can be sure that the reducer is in normal use. It is necessary to adhere to the working condition of hydraulic pump and motor.
