The reducer is an important accessory on the mixer truck. You can understand the function of the reducer when you know the working principle of the concrete mixer truck. The working principle of the mixer truck is to take out the power of the chassis of the special truck through the power take-off device, and drive the variable pump of the hydraulic system to convert the mechanical energy into hydraulic pressure energy and transmit it to the quantitative motor. The motor drives the reducer, and the reducer drives the mixing device to mix the concrete. The reducer will also break down. Many people don't know what to do when the reducer breaks down? Here are two faults and solutions.
Fault 1: oil leakage.
Shaft seal oil leakage is mainly caused by improper use of the reducer or the output shaft of the reducer and foreign matters. At this time, it is necessary to replace the shaft seal or oil seal. During the use of the reducer, the foreign matters at the oil seal should be cleaned in time.
The connection between the end cover and the housing leaks oil. This kind of oil leakage is mostly caused by the loose connecting bolts of the reducer. At this time, it is necessary to retighten the connecting bolts of the end cover and the housing or replace the reducer, or replace the O-ring between the end cover and the housing of the reducer. In order to avoid the recurrence of this kind of situation, the bolt torque should be checked regularly at ordinary times.
The connection between the motor and the reducer leaks oil, which is mainly because the O-ring seal of the motor and the reducer is not up to standard during installation. At this time, it is necessary to replace the O-ring at the connection of the motor and reducer, and check whether the mounting surface of the motor and reducer is scratched. During the normal use of the mixer, pay attention to check whether the bolts installed on the motor and reducer are loose.
Fault 2: Abnormal noise
If the reducer makes abnormal noise during the use of the mixer, check it: check whether there is gear oil in the reducer; Check whether the oil level is normal at the oil level observation window; Drain a small amount of oil to see if there is blackening and deterioration, and check the maintenance time; Check whether the reducer has been impacted by external force. If a large amount of iron chips are found during oil drainage, it means that the internal part of the reducer has been damaged. The reducer must be replaced, and the reducer should be regularly maintained.
The above two points are common faults of the reducer. The fault performance and solutions are for your reference. If you have any doubts or needs, please come to our website Ask about it!
