SKF bearing high temperature of reason analysis and processing method

SKF bearings temperature rise
(1). There are alarm bells ringing.
(2). machine next to hydro-mechanical fault alarm window light that indicates the bearing temperature meter temperature rise, the signal relay.
(3). the thermometer (intumescent thermometer) black and yellow pin coincide or exceed yellow needles.
(4). the issue of bearing temperature rise fault signal.
SKF bearing temperature rise cause
(1). bearing cooling water disruption.
(2). the deterioration of the oil, oil itself is not clean or running oil deterioration, such as increased moisture in oil causes acidity of oil increases, reduces oil lubrication, bearings subjected to corrosion, cause the temperature to rise.
SKF bearing temperature rise
When the bearing temperature rise, first determine whether the malfunction, as did rise, should be dealt with as follows:
(1). check the cooling water pressure, flow and pipe systems are normal. If low water pressure may be filter clogged, not processed in a timely manner, can shut down, when the confirmation work, again put into use.
(2). Governor oil pressure should be checked, if oil pressure may lead to cooling water hydraulic valve is closed.
(3). inspect the bearing for abnormal noise, and test the swing bearing is abnormal.
(4). take oil samples observation of oil color is changing, and tests to see if spoilage. If confirmed when the deterioration, downtime should be replaced with new oil.
(5). check oil oil level is normal, if normal, check whether the tank Vent valve close. If you have already rolled, oil to be filled, if it is a sealant gasket oil leakage, should stop processing.
When we use the SKF bearings, if its very hot cases are found, then hastened to stop device operation, and then find out the reason and processing in accordance with the solution provided above, but may be due to heating in the bearings for different reasons, there are also different ways to resolve the problems, so they should be treated case, completed with the assistance of technical staff.
