Road Sweeper Maintenance

1. In order to avoid operation errors, the control valve of the road sweeper is mainly divided into the main valve and the auxiliary valve. So where is the main difference between these two valves, the power of the main valve comes from the chassis of the road sweeper, and the power of the auxiliary valve comes from the auxiliary engine of the special function part. Common auxiliary engines of road sweepers include Chaochai, Jiangling and Cummins. The main valve manages the tilting of the housing car behind the chassis and the hydraulic switch of the rear door of the car, and the auxiliary valve manages the work of the four floor brushes of the road sweeper (one side or all of them can be controlled individually) and the suction cup.

2. The auxiliary engine of the road sweeper has different power due to different engine brands, but the general speed is about 1500 rpm - 1800 rpm

3. According to the needs of the work, you can generally choose whether to have the function of spraying water and dust. The conventional configuration generally comes with a back spray. At the same time, you should pay attention to whether the water volume of the clean water tank is enough. Generally, the volume of the clean water tank is different, and the working time may be different.

4. The pressure adjustment of the electromagnetic multi-way valve of the road sweeper is generally on the overflow valve, and the user can adjust the pressure appropriately to change the speed of the sweeping brush.

5. In addition, the sweeper can choose whether the left and right ground brushes of the vehicle work at the same time according to the road conditions.

6. There may be fine dust deposits in the garbage bin of the road sweeper, and manual handling is required when cleaning the garbage bin.

7. The distance between the suction cup of the road sweeper and the ground should be adjusted frequently according to the conditions of the road section.

8. Dust and mud may often adhere to the vacuum pipe of the road sweeper, and it needs to be cleaned frequently to achieve better results.

9. When the electrical parts in the control box need to be replaced for more stable use, it is best to remove one piece and replace one piece.

10. Sanitation workers should regularly check whether each functional part is normal

11. In order to prevent foreign matter in the hydraulic oil from affecting the normal operation of the electromagnetic control valve, sanitation workers should regularly check whether the hydraulic oil is normal.

12. Always check whether the limit device of the clutch electric push rod of the auxiliary engine of the vehicle is normal.

13. When the sweeper control button is switched, the time interval should be 5 seconds

14. When a certain hydraulic part of the road sweeper does not work properly, check the oil circuit first and then the circuit according to the steps.

(1) The possible reasons for the abnormality of the circuit part are: disconnection of the fuse, loose connection of the line, and breakage of the line

(2) The possible reasons for the abnormality of the oil circuit are: the failure of the oil pump, the rupture of the oil pipe or the oil leakage at the connection of the oil circuit, and the failure of the solenoid valve.
