Paver technical maintenance

1, daily technical maintenance

(1) clean the paver: remove the surface of the paver accumulation of mud, sticky sand and asphalt; remove the engine, hydraulic components and other components on the surface of the dust, grease. Be careful not to get dirt into the fuel filler and air filter.
(2) Check the heating system of the nozzle, connecting pipe, gas tank and the switch.
(3) Check the connection and tightening of the various parts of the paver, especially whether the connecting bolts of the left and right crawler beams and racks, screeds, dispensers and scraper conveyors are loose or broken and fastened if necessary Or replacement.
(4) check and remove the leakage of various parts.
(5) Check the engine oil, fuel, coolant and the amount of hydraulic oil, and according to the provisions of adding new oil to the oil standard indicator.
(6) Check the amount of grease in the centralized lubrication device.
(7) Check the blade of the screw feeder for cracks, if any.
(8) Check whether the electrical plug is loose.
2, cyclical technical maintenance
(1) running after 50h technical maintenance content
Before putting into use, the paver should be tested for 50h, otherwise it shall not be put into use. For 50h run-in operation, should be used in the engine instructions in the relevant provisions. After the run-in test, the following shall be carried out in accordance with the following:
① replace the diesel engine oil: heat machine put the old oil, and then into the new oil; after short-term operation, immediately check the oil level is in the specified height.
② replace the transfer case and all reducer (including walking, feeding, feeding reducer) lubricants; heat machine put the old lubricants, and then into the new lubricants.
③ replace the oil filter filter.
④ replace the diesel fine filter cartridge.
⑤ Check whether the hydraulic oil reaches the specified amount.
⑥ check the engine coolant level, if insufficient should be added to the prescribed amount.
⑦ Check the heating system of the nozzle, connecting pipe, gas tank and the switch.
⑧ Check whether the rubber track shoe has cracks, such as crack length greater than 50mm, must be replaced.
⑨ check whether the hydraulic system leakage phenomenon, if necessary to be excluded.
⑩ Diesel engine every 50h, must clean up the air filter filter.
Check the blade of the screw feeder for cracks, if any.
Check if the auto leveling device is working properly.
Check the cylinder for leaks, if any should be excluded.
(2) technical maintenance content for every 100 hours of work
① all the daily maintenance of the project.
② According to the use of diesel engine 100h technical maintenance items for maintenance.
(3) technical maintenance for every 200 hours of work
① repeat 100h technical maintenance content.
② According to the diesel engine operating instructions 200h technical maintenance items for maintenance.
(4) 500 hours of technical maintenance of each work
① repeat the 200h technical maintenance of all projects.
② According to the diesel engine operating instructions 200h technical maintenance items for maintenance.
③ check the rack, fuel tank and other important parts of the welding at the crack, track beam with or without deformation. If resolved.
④ check the operation of the switch, control the electrical circuit of the monitoring device is normal, such as damage should be immediately repaired.
⑤ Check the wear of the dispenser.
⑥ check the basic situation of the battery, such as the oxidation of the two poles and so on.
(5) technical maintenance content for every 1000 hours of work
① repeat the technical maintenance of 200h content.
② According to the diesel engine operating instructions 200h technical maintenance items for maintenance.
③ replace the hydraulic oil filter cartridge.
④ replace the diesel engine oil.
In addition to the cyclical technical maintenance described above, a full inspection and maintenance of the paver should be made during the winter of each year. If necessary, replace the lubricating oil of the reducer and the transfer case.
3, long-term parking technical maintenance
If the paver will be parked for 3 months, the following requirements should be maintained:
(1) according to the requirements in the instructions for long-term technical maintenance, and for rust treatment.
(2) Clean the inside and outside surfaces of the machine, hoppers, screeds, screw feeder and scraper conveyor. Should be kept in the warehouse; if placed in the open air, should be placed in the ventilation, and covered with canvas.
(3) the screed with wood blocks up.
(4) hopper, leveling tank to be fully recovered, and coated with grease.
(5) long-term parking, the host can only be equipped with ironing device, the basic part of the sub-device.
(6) random accessories of the paver after cleaning in a good anti-rust treatment, and placed in a clean and ventilated room.
(7) add new lubricating oil or grease to each lubrication point of the paver.
