The process of pumping operation exist many ways spill, which appear to belong to the most active and the driven shaft seal head oil spills, especially where the drive shaft seal leakage is not uncommon. Actual operation found in section reducer Inner tent brakes, the brake wheel drive shaft mounted on one side and the oil spill than serious.
Obtained from the relevant survey, the factors leading to pumping gear oil spills occur in addition, there are the following several factors described above: First, there is the location of oil spills along the gear box combined surface; secondly, along depending on the upper lid hole reducer oil spills position exists; in addition, there are oil spills along the bottom position of the drain hole reducer.
In some relevant information in the case did not fit the oil spill at the surface position of the reducer as a spill way, but clearly points out the need to attach great importance to the real problem, that some combination gear box assembly process, co-box surface will cause some residual iron surface is not fit me tight situations which can result in oil spills.
The author believes that the factors leading to surface oil spills occur close box in addition to the above the outside, more critical is the gear in use for some time, there are different degrees casing deformation, resulting in uneven surface boxes together, the lack of fit rigor, causing oil spills. The main factors leading position as the hole at the hole cover and put the oil spill is not tighten the bolts or gasket is not installed.
