Influence of poor oil quality of Rexroth a4vso250 hydraulic pump

  Effects of poor oil quality of Rexroth a4vso250 hydraulic pump: 1
The characteristics of oil viscosity and temperature used in the hydraulic pump are poor, and the viscosity changes greatly during use
2 the hydraulic oil used contains a large amount of water, resulting in poor lubrication of the hydraulic oil and abnormal heating of the hydraulic pump
3 the oil in the hydraulic pump has not been replaced for a long time, or the hydraulic oil used has been seriously polluted, resulting in the heating of the hydraulic pump

Rexroth a4vso250 hydraulic pump pipeline failure caused the hydraulic pump to heat up: 1
The oil drain pipe connected to the hydraulic pump was flattened or blocked, resulting in failure to drain oil and causing the oil pump to heat up
2
The diameter of the oil discharge pipe of the hydraulic pump is too small to enable the hydraulic pump to discharge oil smoothly and meet the oil discharge requirements
3
The small oil suction pipe diameter of the hydraulic pump makes the oil suction resistance of the hydraulic pump large, so it cannot absorb oil normally, resulting in the heating of the oil pump
