Where does the concrete pump truck need maintenance? ——Maintenance of rotary reducer

Where does the concrete pump truck need maintenance? The following is an introduction to the maintenance of the rotary reducer. Fault phenomenon in the construction of concrete pump truck: The rotary reducer of the small pump truck is easily damaged during use.

Failure analysis of the pump truck in the construction of the concrete pump truck: 1. The rotary reducer of the concrete pump truck is all erected on the lower turntable. 2. The rotary reducer is equipped with a dust-proof enclosure. 3. From the perspective of the reducer structure, only one skeleton oil seal is installed on the output shaft on the facade of the rotary reducer. 4. There must be a gap due to the relative movement of the up and down rotation. 5. The construction environment of the concrete pump truck is poor, and sometimes the concrete pipe will burst during work, which is easy to make the mortar fall into the rotating coaming. 6. Few users take the initiative to disassemble the hoarding for hygiene and maintenance. 7. The mortar is also corroded. After the skeleton oil seal is hardened, water and mortar enter the reducer, resulting in damage to the bearing and gland, rotation failure, and safety accidents may occur in a single reducer.

Troubleshooting of the small pump truck during the construction of the concrete pump truck: as long as the skeleton oil seal is protected from damage, the reducer will not be damaged. If you want to prevent the mortar from entering the reducer, such as changing the material of the dust-proof enclosure, and using hard plastic or soft rubber to make a professional protective abrasive tool, it is obviously unrealistic to seal against dust. Suggestion for improvement of concrete pump truck: Just change the butter for the pump truck half a year. Before the pump truck leaves the factory, the rotary reducer of the new car is greased in the commissioning department.
