Road marking machine in the construction of the time will encounter a variety of problems, may be caused by improper operation or maintenance is not timely, the next briefly.
1, feel the pump does not suck material or suck material difficult.
Possible reasons: because of the cold weather in winter, the temperature is lower, the viscosity of the paint is a little larger than usual, the fluidity decreases, which may lead to suction difficulties.
Solution: use a mixer to fully stir the paint before use, or add the appropriate amount of thinner to reduce the viscosity of the paint, fully stirred.
2, no material and nozzle clogging and other phenomena.
Possible causes: after construction, did not clean up the road marking machine in a timely manner, so that a large amount of paint residue in the pipeline, in the parking process of paint solvent volatilization, residual paint curing in the pump, pipeline.
Solution: clean the equipment in time after construction. In accordance with the cleaning steps in order to clean the pipeline and spray gun nozzle.
3, Uneven coating from road marking machine.
The main reasons are:
Unstable spraying pressure, too much or too little spraying pressure may lead to uneven coating.
Solution: Adjust the spraying pressure to a suitable range to ensure uniform coating.
Unsuitable viscosity of coating material: too high or too low viscosity of coating material may lead to uneven coating.
Solution: Adjust the viscosity of the coating according to the construction conditions to ensure that it is within the optimum spraying range.
Measures such as cleaning the machine in advance, using the correct paint and paying attention to road preparation can be taken to solve these problems.
In short, standardize the use of road marking machine, construction and timely cleaning, usually long placed attention to lubricants, sealing oil, etc., is conducive to prolonging the service life of the equipment.
