What kind of hydraulic oil is used in XCMG XR220 rotary drilling rig?
Rotarydiggingmachine fever is a normal phenomenon, but if serious account of hydraulic oil filter through the difference, the best choice for Shell Tellus s2m46 oil
The hydraulic oil is always fever, that is in the process of using hydraulic oil, because the parts wear or absorb moisture and particles from the air, so that the oil accumulation of fever and aging with wear particles, parts of these impurities will damage the piston rings, bearings, valves and machine oil, and the oil accelerated deterioration, reduce oil service life. In order to make the hydraulic system clean without heating, extended Huanyouzhouqi, reduce maintenance costs, so that the machine is durable, the best solution for loop filter in hydraulic system operation at the same time, in order to fundamentally improve the cleanliness of hydraulic oil, hydraulic oil is not easy to heat.
Summer fever is normal, at about 50-60 degrees on the line, the use of hydraulic oil is no problem, check the system has no leakage, and if there is leakage, and then a good hydraulic oil will also be hot.
