Pavement must be carried out in winter, so running track paver machine is inevitable in winter. However, in the case of low temperature, the equipment is easily affected by the low temperature environment, causing a certain degree of damage. To ensure the efficiency of the equipment in low temperature environments, we need to master certain cold protection measures to reduce equipment damage.
I. Maintenance of the engine
Choose an antifreeze suitable for the local air temperature and replace it every other year. Before the winter comes, replace the winter fuel for the running track paver machine in advance to avoid ordinary diesel from waxing in the filter element and pipeline due to low temperature, which will cause running track paver machine engine does not start normally. Turn on the anti-icing device of the compressed air system and check the ether level regularly. Many engines need to add some additional additives to the coolant, namely SCA (supplementary coolant additive). It usually acts on aluminum. In the process of contacting the manufacturing parts with the coolant, it can more effectively prevent metal corrosion, mineral precipitation, cavitation erosion and foaming of the cylinder liner.
Second, electrical system maintenance
Please start the running track paver machine engine every half month to charge the battery and run all hydraulic actuators, such as rotating hydraulic motors, telescopic cylinders, etc. Do not remove the battery from the machine to prevent long-term parking of the equipment Failure that causes the internal software program of the controller to be lost.
Three, hydraulic system maintenance
Start the running track paver machine on a regular basis and turn on all hydraulic functions on the machine to let the hydraulic drive components work regularly to prevent the related seals from being damaged due to long-term parking and the failure of metal components such as oil cylinder rods. It is possible to retract all the cylinder rods into the oil chamber of the hydraulic cylinder to better protect the surface of the cylinder rod.
四 、 Parts maintenance P
While parking the running track paver machine for a long time in winter, you should do a good job of lubrication and maintenance of the mechanical joints, bearings, check the integrity of the dust cover of each mechanical part, and replace the damaged seals in time. The metal contact surfaces exposed to the air should be rust-proofed. Start the engine regularly and run all reduction gearboxes to prevent shaft seals in the gearboxes. Rubber seals are damaged due to long-term parking and gear oil adhesion.
