L-HM hydraulic oil detection indicators

Hydraulic technology is widely used in industries such as machine tools, metallurgical machinery, engineering machinery, mining machinery, agricultural machinery, automobiles and aircraft, and ships. At present, hydraulic oil testing is generally based on the mandatory national standard GB 11118.1-2011. GB 11118.1-2011 divides hydraulic oil into five types based on its usage: L-HL, L-HM, L-HV, L-HS, and L-HG, namely, anti oxidation and anti rust hydraulic oil, anti-wear hydraulic oil (high-pressure, ordinary), low-temperature hydraulic oil, ultra-low temperature hydraulic oil, and hydraulic guide rail oil.
