Asphalt sprinklers are now the most important road construction machinery for construction of asphalt pavement and road construction machinery. It is mainly applied to the construction of urban roads, highways, ports, docks and airports. Asphalt sprinklers can be used for the construction of pavements, pavements of asphalt, upper and lower seals, and asphalt-infiltrated roads. The vehicles can also be used for transportation of liquid asphalt or other heavy oils. If you want to operate the asphalt sprinkler safely and correctly, you should observe the following points:
1. Before starting the asphalt sprayer, it should be a good observation of whether the valves of the vehicles can be used normally, whether oil leakage or oil leakage occurs.
2. The burner of the vehicle is heated, and the power take-off, inverter, and monitor power are turned on when the air pressure is normal. Careful observation of the start of the good thermal oil valve is not correct, and the pressure is not within the normal range. . Then in the ignition, after the ignition need to see if there is no abnormal combustion burner.
3. When asphalting in an asphalt spreader , the first step is to check if the valve is closed. Careful to avoid the occurrence of oil leakage, when carrying out oil filling, it is also very good to observe whether there is oil leakage at the joint. If there is any abnormality, you should immediately stop loading oil.
4. Before spreading the asphalt, the asphalt sprayer should warm the asphalt pump first. After the temperature is reached, open the asphalt valve and allow the asphalt to cycle for a short period of time. When the sprayer has temperature, it is opened and fixed work is done.
5, asphalt spray truck before spraying, but also need to carefully observe the various processes are not in normal operation, mainly to observe the pump speed, speed and other aspects of the settings. Then open a few or a nozzle to see if there is oil. When spraying, if there is no oil, it should be stopped immediately. When spraying, you should pay more attention to the spraying conditions on the surrounding road surface, see if there are no nozzles that do not spray, and if there is any need for additional spraying. After the spraying work is finished, the sprayer should be closed immediately, and then the pitch and nozzles in the pipeline should be quickly purged.
6. After the purging work is completed, it is necessary to fix the spraying frame of the asphalt sprayer, close the oil outlet valve and the oil inlet valve, and then close the power take off device, monitor power supply, shut off the air, and place the cover of the tobacco pipe. Cover it.
