Bearing temperature rise comparison manifest has the following two situations:
1, there is alarm bell ringing
2, issue of bearing temperature rise fault signal.
3, hydro-mechanical fault light plate light next to the machine, indicates that the bearing temperature meter temperature, signal relay.
4, thermometer (expanded-thermometer) black and yellow needles coincide or exceed yellow needles.
When the bearing temperature rises, first determine if the malfunction occurs, high if it should be done in a timely manner are as follows:
1, first of all check the cooling water pressure, flow and pipeline systems are normal. If the water temperature is probably filter blocks up and cannot be processed in a timely manner, can shut down, when the confirmation work, again put into use.
2, should check the speed Governor oil pressure, if oil pressure may lead to cooling water of hydraulic valve to close.
3, check there is no abnormal sound of bearings, and inspect bearing set, there are no exception.
Observation 4, take oil sample oil color changes, and for testing to see if bad. When you confirm the deterioration should be shut down replace new oil.
5, check the oil level, if it is not correct, check that the tank Vent valve is shut. If you have secured oil supplement, if there is a rubber gasket of sealing oil leakage should stop processing.
In order to prolong its life, we need to note in the daily operation and maintenance of many minute details, to better care and maintenance of bearings. When the bearing when spinning, we should pay attention to what matters. Bearings in high speed rotation, especially speed when close to or exceed the dimension table records of the speed limit, we should mainly focus on the following issues:
1. precision bearings in the bearing should be used;
2. bearing internal clearance to be analyzed and taken into account when the temperature rises the bearing internal clearance is reduced when.
3. analysis of bearing cage material type (for high speed rotation, suitable for cutting copper alloy or phenolic resin cages. Also applies to synthetic resin moulding of high speed rotating cage);
4. analysis of bearing lubrication, is it suitable for lubrication of high speed rotating, spray lubrication and oil mist lubrication and oil-air lubrication lubrication method.
