How does the bitumen distributor spread the bitumen evenly?
Generally, the bitumen spreader is equipped with an bitumen flow meter, a throttle valve, and a speedometer for the spreader. bitumen flow meter is used to record the output of bitumen, throttle valve can adjust the bitumen flow, and the speedometer reflects the travel speed of the spreader.
The volume and viscosity of bitumen change with temperature, so when the temperature of bitumen in the tank of the spreader changes, it will also affect the uniformity of the bitumen spreading.
During the construction process, the spreader is not continuously working or encounters sudden changes in climate. Due to heat loss, the bitumen temperature in the tank decreases, the bitumen viscosity increases, and the volume decreases. The bitumen flow meter cannot accurately measure the output of bitumen. If the temperature is very low, no fan spray can be formed at the nozzle.
In construction, it is generally required that the spray pipe of the bitumen spray machine can adjust the ground clearance, because the bitumen is sprayed through the nozzle to form a fan-shaped spray surface, and the spray surfaces formed by the two adjacent nozzles are interlaced with each other. The degree varies with the height of the spray pipe from the ground, which in turn affects the uniformity of the bitumen spray.
Because the fan-shaped spray surfaces formed by the nozzles interfere with each other and collide to prevent affecting the uniformity of spraying, the installation angle of all nozzles should be the same. The above factors are factors that affect the uniformity of the spreading machine.
