Recently, customers have reported that there is TIMKEN bearing temperature is too high, our technicians say the temperature is too high, TIMKEN bearings a more common phenomenon, the key is we need to know the reason TIMKEN bearing heat, generated by the phenomenon, and then find solution and with a solution. Here briefly about TIMKEN bearing temperature causes and solutions.
TIMKEN bearing temperature phenomenon
(1) an alarm electric bell.
(2) mechanical failure of the machine next to the water wheel disk light plate light, instrument bearing temperature indicates the temperature increases, the signal relay.
(3) thermometer disk (expansion-type thermometer) black and yellow needles needle overlap or exceed the yellow needles.
(4) issued bearing temperature fault signal.
TIMKEN bearing temperature rise causes
(1) bearing cooling water break.
(2) oil degradation, oil, or run their own dirty Petroleum degradation, such as oil in water will cause the oil to increase the acidity increases, will reduce the oil lubrication, erosion of the bearing, causing the bearing temperature .
TIMKEN bearing temperature processing
When the bearing temperature rises, first determine whether the malfunction, if they really rise, should be handled as follows:
(1) Check the cooling water pressure, flow and piping systems are normal.Flow down the filter may be blocked and can not handle, it can stop processing when confirmed to work, and then put into use.
(2) should check the governor oil pressure, oil pressure may result if the cooling water, hydraulic valves closed.
(3) Are there differences in sound check bearings and bearing runout test whether there is an exception.
(4) to take oil samples have observed changes in oil colors, and conduct tests to see whether the deterioration. If confirmed deterioration should be replaced with new oil shutdown.
(5) Check the oil standard oil level is normal, if not normal, check the tank drain valve is tightly closed. If closed, the oil should be added, if it is sealed pad permeability, should stop treatment.
When we use TIMKEN bearings, and if we find that the temperature is high in the case, then quickly stop the equipment operation, and then find out the cause and provide solutions in accordance with the above processing, but may be due to bearing heat for different reasons, So, to solve in different ways, so we should treat specific conditions, with the help of the technical staff to complete.
