Use heat detector to monitor bearing temperatures at any time, and temperature alarm or stop automatically when they exceed a specified value prevents burning shaft accident.
High temperature often indicates that the bearing is in unusual circumstances. High temperature but is also harmful to the bearing lubricant. Sometimes overheated bearings can retain the lubricant in the bearing. If the bearing temperature exceeds 125 ℃ long-term continuous transfers reduce the service life of the bearing. Causes of high temperature bearings including: inadequate or excessive lubrication lubrication, lubricant. Contains impurities, excessive load, ring of bearing damage, inadequate clearance, and oil have high friction and so on.
The importance of bearing to the effect that, when damaged, and will cause the device to shut down, these bearings should preferably be retro-fitting of the temperature probes.
1. detect if the bearing has a different tone, and inspect bearing swing is abnormal.
2. take the oil see oil color changes, and for tests to see if bad. If confirmed when the deterioration, should be shut down replace oil.
3. test speed Governor of hydraulic, hydraulic oil pressure may causing cooling water valve is closed.
4. test equipment cooling water of hydraulic devices, look at the water and piping systems are normal. If the water pressure is very likely filter blocked, cannot be processed in a timely manner, should immediately stop processing, determine work put to use is no problem.
5. detection of oil oil level is normal, if not normal, test the tank Vent valve is closed. If it is closed, oil to be filled, if seal gasket oil leakage should stop processing.
