TRM vertical slow roll oil leakage problem analysis and processing

TRM vertical slow roll oil leakage problem analysis and deal with 2018 - 12 - 22 Zhu He ( Xuzhou sinoma equipment heavy machinery co. , LTD. ) TRM vertical mill in use, some roller oil leakage problems, directly affects the normal operation of the vertical mill. Now in luzhou saide TRMS32 cement company. Three roller mill as an example, combined with field usage, roller structure and analyses the reason of roller oil, and put forward the corresponding improvement measures. 1 problem and analysis of the oil mainly has the following phenomena: 1) Roller set under the outer side, horn set underside, mill and keep-off lateral appear a large number of oil stains. 2) Empty filter and pressure above the rocker arm appeared a lot of the leakage oil stains. 3) Oil lubrication station a cyclical downturn, the oil pressure gauge pressure is zero. 8 mpa, oil pressure gauge pressure is zero. 006MPa。 According to the leak location, infer the oil seal and air filter two abnormal lubricating oil flow, with reference to the lubrication station technical requirements ( See table 1) And combined with the roller structure ( See figure 1) Analysis, the reason mainly has the following several aspects: 1) Oil lubrication station pressure does not conform to the requirements the vertical mill adopts the 'b,' the company lubrication station, require maximum working pressure of 0. 5 mpa, but actual production pressure drop to zero. 8MPa。 Analysis of the reason for not using the recommended N320 lube, but use, is the group's unified purchasing GR - BP company XP1000 lubricating oil. The lubricating oil viscosity is too high, by increasing the oil pressure in the process of production, ensure the oil, after the oil spill, oil level drops, especially by improving the inlet pressure to ensure that input. In addition, GR - XP1000 sports viscosity in 40 ℃ for 1000 CST, than prescribed N320 at 40 ℃ 320 CST viscosity is much larger, less oil return effect. The oil pressure is too large, easy to cause structural damage, skeleton oil seal main lip effect even the sealing effect. 2) Roller oil level is too high a handful of parts of the oil show the oil level in the roller serious too high, not only within the prescribed oil level line ( See figure 1) , but also a serious super oil seal location. Too much of the work roller in the lubricating oil temperature, pressure, high pressure and even cause lubricating oil from the air filter. 3) Vent plug, pressure imbalance had spilled oil, air filter proved empty filter have failed and ash reservoir are more likely to stick on air filter, due to poor ventilation, enter inside roller, oil pressure imbalance. 4) Poor oil spill the oil pressure roller is 0. 006 mpa, is far lower than the normal value ( 0. 02 ~ 0. 04MPa） , back to the oil volume is small, circulation. 2 treatment measures and effect 1) Replacement with specifications of high-quality skeleton oil seal components and air filter, pay special attention to the standardization of the oil seal installation, air filter to do daily protection and maintenance. 2) According to the technical manuals for replacement recommended N320 lubricating oil viscosity, oil filter to change regularly, ensure cleanness of lubricating oil. 3) Clean lubrication piping, especially the back line, ensure the oil circulation is smooth; Clean up the air outlet gas seal device, ensure the roller on air seal export wind is smooth, prevent into the dust, damage the oil seal. 4) E. , adjust the lubrication station inlet pressure to the lubrication station tracking back to the oil pressure and make records, ensure the oil return smoothly; Flow adjusting valve, to ensure the oil, oil return flow balance, closely tracking the lubrication station oil, lubricating oil abnormal situation in the mill. Through the above analysis, the roller oil after take targeted measures, not to appear leak phenomenon, obtain good effect.
