How to maintain the paver?
April 9, 2022
Paver is a kind of engineering machinery for the construction and maintenance of highways and urban roads. When the paver is operating, especially when paving a wide road surface, the reverse blade installed at the front end of the hanger can prevent the segregation of the mixture; If the blade is overstressed and broken, it becomes one of the vulnerable parts of the paver, requiring extremely high wear resistance and toughness.

The fact that the paver can pave a flat road is caused by the floating principle of the paver screed. During the operation of the paver, the screed is in a floating state. Various forces on the screed, such as the weight of the screed itself, the buoyancy of the material, the traction force of the paver host and the resistance of the material are all in a state of balance, so that the height of the rear edge of the paver screed remains unchanged, thereby paving the Flat surface. If the external interference, such as the main body of the paver floating up and down caused by the original unevenness of the roadbed, will bring about changes in the elevation angle of the screed, thereby affecting the flatness of the layer. The function of the self-leveling device is to cause the elevation angle of the screed When the changing factors of , automatically pass the movement of the leveling cylinder, keep the position of the drag point A unchanged, eliminate the interference and pave the smooth road.

If the paver will be parked for 3 months, technical maintenance is required:
(1) Perform technical maintenance for long-term parking according to the requirements in the instruction manual, and perform anti-rust treatment.
(2) Clean the inner and outer surfaces of the machine, the hopper, the screed, the screw distributor and the scraper conveying device. It should be parked in the warehouse as far as possible; if it is placed in the open air, it should be placed in a ventilated place and covered with canvas.
(3) Pad the screed with wooden blocks.
(4) The hopper should be fully retracted and greased.
(5) When parked for a long time, only the basic part of the ironing device and the material distribution device can be installed on the main machine.
(6) The random accessories of the paver should be treated with anti-rust after cleaning, and placed in a clean and ventilated room.
(7) Add new lubricating oil or grease to each lubricating point of the paver.
