The use of road rollers is very common, but there are various problems in the use of road rollers, which affect the operation, delay the construction period and increase unnecessary maintenance costs. Therefore, our operators should not only be able to use the roller, but also learn to judge some basic faults and carry out maintenance. The following Jinan road machinery equipment manufacturer will explain to you several problems that often occur and the solutions. I hope it will help you.
Fault: the road roller emits black smoke
Solution: check whether the injector injects too much fuel, which leads to insufficient combustion. At this time, we should carry out the cylinder breaking test of the starting roller. Or check whether the clearance of the intake valve is within a reasonable range and whether the air filter element is blocked. And check whether the quality of diesel is bad.
Fault: insufficient pressure
Solution: whether the oil filter of the road roller is blocked, the set pressure of the pressure limiting valve is too low, and the pressure of the pressure limiting valve is limited when necessary.
Fault: unstable idling and flameout
Solution: the hydraulic oil circuit is blocked. Please check the system pressure at idle speed and whether the oil return filter element is blocked. The output power of the roller is too low. Analyze the output of the starting roller in combination with DX data.
Fault: the roller is difficult to start or cannot start
① The engine temperature is too low, and the diesel is not easy to evaporate and burn.
② Poor atomization of fuel injector
③ The oil supply time is too late.
④ The fuel supply is too small and the mixture is too lean.
⑤ There is too much air leakage in the cylinder, and the ignition temperature cannot be reached after compression.
It is very important for our operators to learn to master and judge mechanical faults. It is a waste of time to find someone to repair or return to the factory for repair, which will delay the construction period and increase unnecessary costs.
