Maintenance points of asphalt spreading trucks in different working hours
Maintenance points of asphalt spreading trucks in different working hours
per month (or every 200 hours worked);
Per year (or every 500 hours worked);
Every two years (or every 1,000 hours worked);
per month (or every 200 hours worked)
1. Check whether the asphalt pump fasteners are loose, and if so, tighten them in time;
2. Check the lubrication condition of the servo pump electromagnetic clutch. If there is lack of oil, add 32-40# engine oil;
3. Check the burner pump filter, oil inlet filter and nozzle filter, clean or replace them in time
Per year (or every 500 hours worked)
1. Replace the servo pump filter:
2. Replace the hydraulic oil. The hydraulic oil in the pipeline must reach 40 – 50°C to reduce the oil viscosity and fluidity before it can be replaced (start the car at room temperature of 20°C and let the hydraulic pump rotate for a period of time to meet the temperature requirements);
3. Re-tighten the fixed connection of the asphalt tank;
4. Disassemble the nozzle cylinder and check the piston gasket and needle valve;
5. Clean the thermal oil filter element.
Every two years (or every 1,000 hours worked)
1. Replace PLC battery:
2. Replace thermal oil:
3. (Check or replace the burner DC motor carbon brush).
Regular maintenance
1. The liquid level of the oil mist device should be checked before each construction. When there is a lack of oil, ISOVG32 or 1# turbine oil must be added to the upper limit of the liquid level.
2. The lifting arm of the spreading rod should be lubricated with oil in time to prevent rust and other problems from long-term use.
3. Regularly check the heating fire channel of the thermal oil furnace and clean the fire channel and chimney residues.
