How to deal with the heavy steering wheel of dynamic compaction machine? What are the reasons for heavy steering wheel of road roller? How to eliminate it? What are the main reasons for heavy steering wheel and its elimination methods? Dynamic compaction machine rental Xiaobian to tell you:
If the temperature of steering hydraulic oil is too low, it should wait until the hydraulic oil temperature of small roller rises
The steering pump is not supplying enough oil. Check whether the oil pump is worn or damaged. If it is serious, replace the oil pump assembly. Air enters into the steering oil circuit, causing the steering cylinder to move or not. Remove the air from the system and check the steering pump suction pipe for looseness and air leakage.
Lease of dynamic compaction machine
The pressure of the steering system of the dynamic compaction machine is low. The pressure of the overflow valve should be adjusted according to the regulations, or the overflow valve should be cleaned, and the spring or sealing ring should be replaced.
Bumblebee reminds you that since the steering pressure of the roller with full hydraulic steering gear is too low, it should be overhauled according to its different models.
For the full hydraulic steering gear, the bolts of the metering motor of the steering gear may be too tight, so the bolts should be loosened. It is also possible that the steel ball check valve in the steering gear fails, so the dirt should be cleaned out to make the steel ball contact with the valve body sealing belt well.
