The excavator mini earth digger power of the excavator engine is seriously reduced.
The reasons for the loader 918 decline of excavator engine power are as follows:
1) The new 5t mini excavator engine electronic signal transmission system (mainly for models 3.5 ton excavator with high degree of electronic control) has sensor failures, such as temperature sensor, speed sensor, accelerator motor position sensor, EGR (secondary cycle sensor) sensor, etc. It depends on how the engine power and hydraulic power are matched, That is to say, the electronic optimization system asks for those engine signals to make the household mini excavator dynamic power of the engine constantly changing match the dynamic power required by the hydraulic system.
2) The ers12tv everun low-pressure fuel system is blocked (mainly including the filter element inside the fuel tank and the filter element outside the fuel tank are blocked) or the pipeline is not tightly sealed and enters the air.When excavator rippa 18pro using the correct method of draining and changing oil, the oil temperature should reach 40-50 ℃, and the oil flow should be discharged while stirring, and dirty oil should be completely drained as much as possible; When refueling, a fuel dispenser with a filtering device should be used to add oil. www.haiqinmachinery.com
