Asphalt spreader is an indispensable construction machinery in road construction. But we still need to pay attention to the following problems in the selection of asphalt spreader.
In the technical specifications of highway construction, the quota of asphalt spreader is stipulated. The flow rate of asphalt pump and its speed also have an impact. For the asphalt spreader with professional engine driven asphalt pump, its speed and speed can be adjusted by the engine. Therefore, the close cooperation of the two, make reasonable adjustment, in order to achieve good spraying effect. Therefore, when we select the asphalt spreader, we should not only look at its external quality, but also according to its various performance, such as the flow of the asphalt pump, and whether the speed is consistent.
What should be paid attention to in daily operation of asphalt spreader? That's the key!
1. When the spreader with full load is running, it should run at medium speed. In case of curve or downhill, it should slow down in advance to avoid emergency braking as far as possible; This is because the asphalt in the asphalt tank is liquid fluid, the vehicle is unstable and easy to deviate during driving, which is more serious in the above cases.
2. Check whether the machinery, spraying device, protection and fire prevention equipment are complete. When the fixed spray lamp is used to heat the fire pipe of the asphalt box, the chimney opening on the asphalt box should be opened first, and the spray lamp can be ignited only after the liquid asphalt submerges the fire pipe. When the flame of the heating blowtorch is too large or spread, the blowtorch should be turned off immediately, and then it can be used after the excess fuel is burned out. Before using the blowtorch, the oil suction pipe and the feeding port should be closed first, and the portable blowtorch should not be close to the inflammables after being ignited; Do not use heating system when driving.
3. The driver of asphalt spreader should cooperate closely with the operator on the machine, and the operator should pay attention to his own safety. No one is allowed to stay within 10m in the direction of spraying asphalt to avoid accidents.
