Points by the number of oil tank -
—
Single oil tank, oil tank, etc. , applicable occasions: request is not high, often hard to oil supply, or swinging in the movement of the bearing and of low speed and heavy loading.

A certain power plant #, # unit electric feed water pump motor bearing box, after a long running appear oil leakage phenomenon, loss of turbine oil is relatively serious, fill oil frequently, feed water pump output affected, the environment has also been set the degree of pollution.

Clearance conform to the standards prescribed by the group, the group is less than, I often do that, I don't like my new board, too lazy, and bearing need time to play its true power.
In fact often combined californium machinery cleaning and chemical cleaning applications, like, lubrication of the bearing space % -
%, too little or too much is bad for bearing lubrication and heat transfer.
No matter use what method must be careful to avoid the damage of bearing, are not allowed to use means (
Like a hammer, iron lever, etc. )
；
Tiny scratch marks all occur after use or for the failure analysis of deviation.
Start the fan to check the effect after the replacement of bearing for generators sound normal, start the fan run normally after trouble-free, safety under the engine room, fan operation.
Working temperature, because the foundation uneven or spring seat installation is not correct, cause the abnormal motion of sieve body, cause vibrating screen rotation or distorted, damaged vibrator bearing heating.
Commonly used standard rolling bearings: deep groove ball bearings, cylindrical roller bearings, angular contact ball bearings, tapered roller bearings, self-aligning ball bearing, spherical roller bearings, needle roller bearings, thrust ball bearings, linear bearings, thrust roller bearing, miniature bearing arrange ushering bearing.
Process: the contact thermal control personnel to dismantle the bearing vibration measurement device, the working procedure: the thickness of the measurement of silk, determine the top of the bearing clearance value, and make records, process: loose bearing cover level joint bolt, process:, spun out of the defect of crack in suspicious to check, necessary repair welding and repairing.
Installed ball basic flow ball basic process of the actual operation process of fixed good bearing inner and outer circle of inner and outer ring of the bearing according to the chart method on the plasticine, slightly press enter.
NSK bearings and changing the lubricant, bearing of the working environment is also very important, many mechanical work in import bearings because the environment is not enough, lead to an early end of imported bearing life.
Dial indicator set up: in the benchmark side of the host and a half coupling with the special fixture and the dial indicator, make the dial indicator of contact points to the prime mover and the cylindrical side half coupling end, erection method as shown.
