The induced draft fan impeller side due to heat expansion, bearing box increases;
Temperature bearing box expansion in the operation of hydraulic coupling, bearing, so look for timing motor is higher, the reserved amount according to the size of the temperature parameters of the equipment features and operation.
Installed generators tail junction box and connected with the slip ring room, when bearing radial clearance increases, has the function of angular contact bearings can withstand a large axial load.
Grease metamorphism caused frequent motor bearing fault, repeated down let companies struggling to keep up!
Reliable lubrication is, of course, all open, the single block or the sealed bearing motor's dream.
Common causes of roll passage for lack of grease, grease filling uneven, the poor quality of aging, lubricants selection error, etc. , to solve the problem, only need to use the appropriate lubricant, filling in time, change in time will be able to solve.
；
Basic clearance group, on average, if the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, then must stop running and take necessary precautions.
Repair process analysis of the traditional repair: repair welding is used by domestic as for axial wear, shaft sleeve, pitting, etc. , if the short downtime and spare parts, and will use a new shaft.
New version of the front face two form grille area still have some increase, the redesigned form of blackened head lights on both sides sharp combination model is also very strong, the inside parts using the LED light source, the overall identification recognition degree is very high;
Gears to cover lines above and harsh toward the middle, full of the feeling of power.
Sauvy axial wear online fast repair technology analysis: sauvy carbon technology is a kind of material application technology of polymer materials, is the use of the comprehensive performance of materials and targeted repair process repair worn parts, parts to restore the original size tolerance and meet the equipment operation condition, equipment in order to achieve the purpose of application for a long time.
Lead bronze, strong adhesion, suitable for high speed and heavy-duty bearing, high strength and hardness of the aluminum bronze, poor ability to resist adhesive, suitable for low speed, heavy-duty bearing.
In the realization of the design, the safety factor of the screw and barrel of big, second order is barrel and reducer coupling bolt, the nose and the barrel of the coupling bolt, and the safety factor of safety pin or security key is small.
Welding material: A or A size & amp;
#;
, usually, small shaft choose ball bearing;
Big shaft choose cylindrical roller bearing, spherical roller bearing, tapered roller bearings,
Sometimes also can choose the ball bearing)
。
C < P or less, the influence of working temperature bearing work, due to the friction heat and other reasons, the temperature of the bearing ring is often higher than the temperature of the matching parts.
