The working efficiency of asphalt paver is measured according to its productivity, so how to calculate the productivity of paver? Let's study it together. The productivity of asphalt concrete paver is calculated according to the weight (tonnage) of paving material required per hour. The formula is as follows: Q = 60H.B.V.P(t/h) Q: productivity (t/h) H: paving thickness (m) B: paving width (m) ) V: Paving speed (m/min) P: Mixture density, generally take 1.8t/m3 RP601L, RP700L paver's maximum production capacity of 400 t/h, paving width, speed, thickness should be selected within the rated productivity range.

Below is a brief introduction and knowledge sharing of our company on Paver accessories series.

1. How to adjust and select the width of the ironing plate?

Answer: The ironing plate of each type of paver has a basic width, that is, the minimum width. The method of widening the ironing plate is that the single-layer ironing plate adopts splicing method and the double-layer ironing plate adopts hydraulic method. At this time, the combination principle is that the pavement longitudinal joints under the combination width are the least, and the remaining last pavement is slightly larger than the basic width of the ironing plate. In this way, it can not only ensure the quality of the road surface, but also save man-hour, and avoid the shortcoming of having to use manual paving because the last one is too narrow.

2. How to maintain the hydraulic system in the use of paver?

Answer: In the use of paver, good maintenance of hydraulic system can greatly reduce the failure. In general, attention should be paid to the use of clean containers before adding hydraulic oil to the tank, and the hydraulic oil must be filtered through the filter and then added to the hydraulic oil tank; the replacement cycle of hydraulic oil depends on the quality of the oil used (generally 1000 hours to replace once); the replacement of hydraulic oil should be carried out at working temperature.

3. How to do the daily technical maintenance of paver?

Answer: (1) Clean paver: remove the accumulated mud, clay and asphalt on the surface of paver; remove dust and grease on the surface of engine, hydraulic components and other components. Be careful not to get dirt into the filling ports and air filters. (2) Check the nozzles, connecting pipes, gas tanks and switches of the heating system. (3) Check the connection and tightening of all parts of the paver, especially whether the connecting bolts of the left and right track beams and frame, ironing plate, dividing device and scraper conveyor are loose or broken, and tighten or replace them when necessary.
