How to deal with the bearing temperature is too high
(1) The alarm bells will ring.
(2) machine next disc water wheels mechanical failure light plate light, the instructions bearing temperature meter temperature increases, the signal relay action.
(3). The thermometer disc (intumescent thermometer) black pin with yellow needle coincidence or exceed the yellow needle.
(4) issued by the bearing temperature rise of the fault signal.
2. Bearing phenomenon causes:
(1) of the cooling water may be bearing interrupt, causing the phenomenon.
(2) may be bearing oil deterioration, the oil itself to unclean or run Zhongyou deterioration. Such as the increase in moisture in the oil will cause the acidity of the oil is increased, will reduce the lubricating effect of the oil, so that the pad of corrosion, thereby causing the phenomenon of the bearing temperature.
Bearing phenomenon approach.
When the bearing temperature, the first first determines whether there is a malfunction, if the temperature at elevated should be done immediately following processing:
(1) Check the cooling water pressure, water flow, and piping systems are normal. Ruoshui depression may filter clogging, and can not be, can stop processing when the confirmation to work, and then put into use.
(2). Governor oil pressure should be checked and, if the low oil pressure may cause the cooling water hydraulic valve closed.
(3) check bearing different tone, and detection of abnormal bearing runout.
(4) take oil samples observed oil color change and conduct tests to see whether the deterioration. If confirmed deterioration, should be down to be replaced with new oil.
(5) Check the oil standard oil level is normal, if not normal, check sump oil drain valve is closed. If closed, fill oil, seal oil leakage, should stop treatment.
The assembling foreign body to prevent: the iron filings into the bearing internal bearings can easily be mounted on the rotor to be balanced dynamic balance therefore preferably mounted bearings do balancing. Some manufacturers in order to facilitate assembly, the bearing indoor assembly coated with oil or grease for lubrication effect, but often operating staff is difficult to control the amount of, oil or grease in the bearings indoor accumulates more in the rotation of the bearing. easy to enter the interior of the bearing along the shaft. Bearing chamber is preferably not coated with oil or grease, such as non-coated not have to control may not bearing indoor accumulates.
Serious raw lacquer rust prevention: paint rust characterized is multiple in the sealed type motor, the motor assembly sound good, but put in the warehouse for some time, the motor abnormal sound change, remove the bearing rust phenomenon. Many manufacturers will be considered bearing our continuous publicity Motor Factory have realized mainly insulating paint. The problem is mainly due to the insulating paint out of the volatile acidic substance in the formation of corrosive substances, a certain temperature, humidity, corrosion bearing channel leading to bearing damage. The problem can only be a good selection of insulating paint, assembly and after the ventilation period of time after drying.
The bearing assembly: because the bearings are high precision products, such as improper assembly bearing channel easily damage, leading to bearing damage. The bearing assembly should have a dedicated mold can not beat, only a small circle force pressed into the shaft, the pressure of the big circle can only large circle force. Assembly requires the use of pneumatic or hydraulic press-fit upper and lower die outside the state level, tilt, if any, the bearing channel will result in damage due to power, the bearings produce a guide ring.
