The rubber paving machine is mainly used in the construction of highways. It is a product of many materials on the road. Its main functions can be divided into two categories, one is paving gravel stones, and the other is paving asphalt and concrete. Such as pavement materials, this is an indispensable machine in the construction proposal of roads.
When choosing a road paver machine, the main consideration is the walking ability of the paver and the hydraulic system. For road rolling equipment, the uniform and slow speed is more conducive to the paving of the road, so the driving speed and stability need to be considered when selecting the walking capacity of the paver machine; the hydraulic equipment provides energy for walking, so the hydraulic system of the paver is stable Sex is also the choice of road paver machine needs to be compared with each other. In addition to the comparison at the time of purchase, the maintenance work of the rubber paving machine is also essential.
In addition to the comparison at the time of purchase, the maintenance work of the runway rubber paving machine is also essential. Let's listen to our company's professional rubber paving machine experts to introduce several problems often encountered in paver machine maintenance work
The engine oil with the correct label should be added to the engine. If the label is too low, it will increase the wear of the engine and the cooling effect will be poor; if the label is too high, it will also increase the wear and shorten the service life of the piston ring. When the oil in the engine oil pan is insufficient, the crankshaft, connecting rod journals and main bearings will be poorly lubricated due to the small amount of oil, resulting in tile burning. However, adding too much oil will increase the rotational resistance of the crankshaft, increase the amount of oil splashed on the cylinder wall, and increase the carbon deposition in the combustion chamber. As a result, the output power of the engine decreases, the wear of parts increases, and the exhaust emission exceeds the standard. Therefore, the amount of engine oil should be controlled between the upper and lower scale lines of the oil dipstick.
2. Cooling fan belt is too tight
In summer, the temperature is too high, and some people mistakenly believe that increasing the tension of the cooling fan belt will improve the cooling effect of the engine. However, if the belt is too tight, it will not only elongate or break, thereby shortening the service life of the belt, but also cause the generator and water pump bearings to be overloaded due to excessive tension, aggravate the wear, and increase the power consumption of the engine. Therefore, the tightness of the cooling fan belt should be adjusted according to the technical requirements.
3. When replacing hydraulic oil, only drain the oil in the oil tank
The hydraulic components on the paver are numerous and require sufficient hydraulic oil. When the hydraulic oil needs to be replaced due to long-term deterioration, some people mistakenly believe that it is only necessary to drain the oil in the hydraulic oil and fill up with new hydraulic oil. However, there are still a lot of old hydraulic oil left in the cooler, hydraulic oil pipe and hydraulic control valve at this time. When the equipment is used, the mixed use of old and new oil will accelerate the rate of deterioration of new oil. The correct oil change procedure should first drain the hydraulic oil in the hydraulic oil tank and the cooler, clean the oil tank and add new hydraulic oil; then remove the circuit header, start the engine and run it at a low speed, make the oil pump work, operate each mechanism separately, rely on The hydraulic oil discharges the old oil in the circuit one by one until new oil flows out from the oil return main pipe; then connect the oil return main pipe to the oil tank, and add new hydraulic oil to the oil tank to the specified position.
4. Gear oil is not replaced for a long time or inferior gear oil is added
Due to the slow travel speed of the road paver machine, and the original gear oil will not change color after long-term use, some people mistakenly think that the wear of the reducer is also slow, and it is difficult to buy the original gear oil in the market, and the speed of adjusting the goods from the manufacturer is slow. At the same time, the construction period is very tight, and many drivers choose not to replace the gear oil or add inferior oil. These practices are inappropriate. To judge whether the gear oil has deteriorated, it is not only by the color, but also the viscosity and the content of iron filings. Gear oil plays a very important role in prolonging the service life of the traveling motor and maintaining its normal operation. It should be fully paid attention to in the usual road paver machine maintenance work.
