Evaluation of tractor biodegradable hydraulic fluids on the basis of hydraulic pump wear
test bench cleanliness level flow efficiency agricultural tractor fluid temperature
2014/2/24
Two types of biodegradable hydraulic fluids (HEES and HEPR) with the mineral oil-based hydraulic fluid (HV) were
compared. The tests were performed using a test bench. During the tests with a tracto...
