The rolling bearing temperature analysis
1. The reason:
(1). The rolling bearing cooling water break.
(2). The degradation of oil, the oil itself not clean or operation of zhongyou degradation, such as the water will increase oil caused by the oil acid increases, will reduce the oil lubrication, that bush was corrosion, cause the rolling bearing temperature.
2. Phenomenon:
(1). Alarm bells ringing.
(2). The machine mechanical failure light hydraulic plate zhong bright, rolling bearing temperature meter instructions temperature, signal relay action.
(3). The thermometer plate (intumescent thermometer) black needle and yellow needle coincidence or more than yellow needle.
(4). A rolling bearing temperature fault signal.
3. Treatment
When rolling bearing temperature, the first judge whether misoperation, such as do rise, should do the following treatment:
(1). Check the cooling water pressure, water flow and pipeline system is normal or not. If water down may be filter jams, cannot be handled in time, can stop processing, when confirmed that can work, and put into use.
(2). Should check the governor hydraulic, if hydraulic low may lead to cooling water hydraulic valve closed.
(3). Check whether the rolling bearing has the different sound, and testing the rolling bearing a degree are normal.
(4). Take fuel samples observation oil whether change color, and laboratory test to see if metamorphism. If confirmed degradation, should stop replace new oil.
(5). Check the oil standard oil case is normal or not, if abnormal, so check valve is vital to oil. If already matter, should fill oil, if is sealed plastic mat oil leakage, should stop processing.
