Someone asked such a question: F&Z bearing temperature of 110 degrees can be?
We believe that, in fact, the number of temperature, it is not what can not, after all, this is not a human can control.
When the F&Z is in a worse time part of course bearing, will cause the phenomenon of high temperature. This is not to discuss what the temperature is good, but must pay attention, to avoid heating problems of F&Z bearing. F&Z bearing, in order to avoid failure due to thermally induced, or even result in bearing damage can not be used.
Here, we discuss the F&Z bearing high temperature phenomenon.
1.F&Z bearing high temperature causes the phenomenon:
(1) may be interrupted F&Z bearing cooling water, produced at high temperatures.
(2) may be F&Z bearing oil, waste oil deterioration or run their own CPC degradation. If the oil in the water will cause the oil, to increase the acidity increase, reduce the oil lubrication, bearing corrosion, temperature, resulting in F&Z bearing phenomenon.
2 when what phenomenon will F&Z bearing temperature too high?
(1) the alarm will ring.
(2) machine disc turbine machinery fault light plate light, instrument bearing temperature indicating increasing temperature signal relay.
(3) thermometer tray (expansion type thermometer) black and yellow needle overlap or over yellow needle.
(4) send a temperature bearing fault signal.
When the F&Z bearing temperature rise, the first action must first determine whether there is a mistake, if temperature is high, should be treated immediately, do the following:
(1) check the cooling water pressure, flow and pipeline system is normal. Down stream of the filter may be blocked, can not handle, it can confirm the work to stop the treatment, and then put into use.
(2) should check the governor oil pressure, oil pressure may result if the cooling water, hydraulic valve closed.
(3) examine whether there were differences in the bearings and bearing sound swing test whether there is abnormal.
(4) take oil samples to observe the color change of oil, and tested to see whether the deterioration. If confirmed deterioration, should be replaced with new oil shutdown.
(5) check the oil level gauge oil level is normal, if not normal, check the water drainage valve seal. If closed, oil should be added, if the sealing gasket permeability, treatment should be stopped.
